Bored piles production method
Bored piles can vary significantly in diameter from 30 to 300 cm and are constructed using different methods depending on soil conditions and load requirements. Common construction techniques include fully cased, partially cased, uncased, and fluid stabilized excavation using tools like grabs, augers, buckets, and chisels to drill the borehole before installing reinforcing and concrete.
Behaviour of piles under the effect of lateral loading in sandy soil
This document summarizes an experiment on the behavior of piles in sandy soil under loading. The experimental setup involved a metal box filled with layers of sand that was compacted to a specific density. A deflectometer was used to measure the displacement of a model pile made of PVC pipe as loads were incrementally added. Load and deflection measurements were recorded over time. The LPILE software was used to model the experiment and generate graphs of deflection versus load, bending moment versus depth, and lateral deflection versus depth. The results provide insight into how piles transmit and resist loads in loose sandy soils.
Shaft boring methods
This document discusses modern shaft boring technology as an alternative to conventional shaft sinking methods using explosives. Shaft boring involves using tunnel boring machine principles vertically to excavate shafts. Key points covered include:
- Shaft boring machines use a cutter wheel and clamshell buckets to excavate material without explosives or drilling/blasting.
- Methods include full-face boring, shaft coring, combined methods, and raise boring/reaming using pilot holes.
- Equipment includes tricone bits, shaft boring machines, reamer bits, and hoisting systems.
- Shaft boring is more economical than conventional methods for shafts deeper than 800 meters and allows for thinner linings, better safety
High speed mechanised shaft sinking
Mechanized shaft sinking methods such as shaft drilling, shaft boring, raise boring, and box-hole drilling have advantages over conventional drill-and-blast methods including higher sinking rates, improved safety, and reduced costs. Shaft boring machines excavate the full shaft diameter simultaneously while shaft drilling reams the shaft from an initial pilot hole. Recent developments include the vertical shaft sinking machine for shallow depths and soft rocks, and the shaft boring machine paired with pilot hole drilling for deep shafts in hard rock. Mechanized methods allow for simultaneous excavation, mucking, and ground support.
Different Raising Techniques in mining
This document discusses various techniques for raising, which is the vertical or steeply inclined excavation that connects different levels in underground mines. The key raising techniques discussed include open raising using drilling and blasting in short lengths, compartment method which divides the raise into sections, Alimak raise climber which uses a rack and pinion mechanism, longhole raising using long parallel drill holes, drop raising which uses large diameter blast holes, Jora hoist with a caged platform, and raise borers which drill and ream a circular raise without explosives. The Alimak raise climber is noted as generally the best adopted technique, first used in India in 1972.
Rock bolts simon madiro
This document discusses different types of rock bolts used in underground mining excavations. It describes mechanically anchored, grouted anchor, and frictional anchor bolts. Mechanically anchored bolts use an expansion shell or resin to anchor into the rock. Grouted anchor bolts are inserted into a borehole and cemented in place with resin or cement. Frictional bolts like split sets are forced into an undersized hole to provide support. The document also outlines the unconfined compression test procedure used to evaluate rock strength in a laboratory.

The document summarizes details about a construction project to build an income tax complex in Rajbagh, Srinagar. It included 8 buildings on a 1375 sqm site with a total cost of 19 crores and completion date of 20/12/2017. The contractor was P.V. Techno Constt. Company and the architect was CP & DS Associates. It also provides information on pile foundations used, including different pile types, materials, uses, and details on pile construction methods for this specific project.
Rock bolt and anchoring
Rockbolts and dowels are used to support underground excavations. Rockbolts are tensioned steel rods anchored with mechanical anchors or resin, while dowels are untensioned steel bars grouted into rock. Different support methods are used depending on rock mass properties and stress levels, ranging from spot bolts to heavy bolting patterns with mesh and shotcrete. Mechanically anchored rockbolts work via expansion shells, while resin-anchored bolts provide stronger anchoring, especially in weak rock. Hollow core bolts and resin grouting provide more reliable permanent support by filling the annular space to prevent corrosion.

It provides details on the purpose and operation of loaders, backhoes, scrapers, excavators, graders, and various types of rollers used for soil compaction. Dump trucks are also mentioned as an alternative to scrapers for transporting excavated soil.
CLAM SHELL BUCKETS
This document discusses clam-shell buckets and tractors used in construction. It defines a clam-shell bucket as a two-piece articulating bucket used for digging and excavation. Clam-shell buckets can be hydraulic or mechanical and are designed for durability, strength, and productivity. They are commonly used for dredging, excavation, and material handling. Tractors are multipurpose machines used mainly for pulling equipment. They can be crawler type for loose soils or wheel type for higher speeds on roads. Crawler tractors are slower but more powerful while wheel tractors are faster but handle lighter loads.
Shaft sinking.
Shafts serve several important functions in mines including transporting workers, coal, supplies, and water as well as providing ventilation, power, and communication. Shafts must be carefully designed and constructed to safely and efficiently carry out these various jobs. A pair of shafts is necessary to allow for redundancy in case one shaft breaks down and to properly ventilate the mine with intake and return air flows. Complex winding and loading/unloading systems using cages, skips, and tubs are used to raise and lower materials through the shafts.
Working of dragline
The document provides information about dragline excavators used in opencast mining. It discusses how draglines work by excavating material and dumping it without conveyors or trucks. Key points include that draglines are flexible and cost-effective for removing waste material. They work by dragging a bucket along the ground, lifting it, swinging it, and then dumping the material. The document also provides details about different dragline operation methods and specifications for draglines used at particular mining sites.
Tutorial 2 (1)
This document compares end bearing piles and friction piles. End bearing piles transfer loads through their base onto a firm soil layer, acting like a column. Friction piles transfer loads through skin friction along their length as they have no firm layer. Precast piles are constructed by driving piles into the ground using pile drivers. Continuous flight auger piles have advantages like low vibrations, quick installation, and not requiring casing. Reinforced concrete piles are manufactured through a process including forming steel cages, placing concrete in molds, curing, and demolding. When placing concrete in piles through a tremie pipe, the pipe must be kept full of concrete and the top raised above cutoff level to prevent soil or water from entering the pile.
Pile foundation -sunil kumar mohapatra
The pile foundation uses piles to support structures where soil conditions are poor. Piles can be placed individually or in clusters. Piles are adopted when loose soil extends to great depths and are used to transmit structural loads deep into the ground. Common pile materials include timber, steel, and concrete. Piles can be load bearing, transmitting loads through end bearing or side friction, or non-load bearing, used for retaining walls or cofferdams. Proper pile spacing, load testing, and installation methods like driving or boring are important to develop sufficient foundation capacity.

CHAPTER 5 DEEP FOUNDATION (2)7788788.ppt
This document discusses deep foundations and pile foundations. Deep foundations are needed when adequate soil capacity is not available near the surface and loads must be transferred to deeper, firmer layers of soil. Common deep foundation systems include caissons and piles. Piles transmit structural loads deep into the ground. They can be classified as end-bearing or friction piles depending on how the loads are supported. Various types of piles include precast concrete, steel, composite, and bored piles which are formed by excavating soil and filling with concrete. Pile foundations are tested to confirm their design and load capacity before full construction.
Well Foundation
Well foundations are a type of deep foundation used when heavy loading is required. There are three main types - box caissons, open caissons (wells), and pneumatic caissons. Well foundations have been used in India for hundreds of years in structures like bridges and buildings. Open caisson foundations, also called wells, are boxes open at the top and bottom that are sunk into position. The document then describes the components and design considerations of well foundations, including shapes, loads, sinking procedures, and construction details.

This document discusses different types and uses of pile foundations. It begins by defining piles as long slender foundation elements that transfer structural loads into deeper, competent soils. Piles are classified based on their construction method (driven or cast-in-place), material (timber, steel, concrete), load transfer mechanism (friction or end bearing), shape, and size. Common pile installation methods include driving piles using hammers, boring piles mechanically, or vibrating them into place. Piles are used as deep foundations when shallow foundations are insufficient, to transfer loads below scour depths or compressible soils, and to control vibrations.
POWER POINT PRESENTATION ON pile_foundation_1.ppt
This document discusses different types and uses of pile foundations. It begins by defining piles as long slender foundation elements that transfer structural loads into deeper, competent soils. Piles are classified based on their construction method (driven or cast-in-place), material (timber, steel, concrete), load transfer mechanism (friction, end bearing, or combination), shape, size and function. Common pile installation methods include driving piles using hammers, boring piles mechanically, or vibrating them into place. The document also outlines different pile uses such as providing end bearing capacity, anchoring structures, absorbing vibrations, and protecting waterfronts from impacts.
Different types of pile
This document provides information on pile foundations, including when they are used, their functions, types, and construction methods. Pile foundations are used when the soil at shallow depths does not have adequate bearing capacity. The key points are:
- Pile foundations transmit loads from structures to deeper, stronger soil layers through end bearing, friction, or both.
- They are used when shallow soils cannot support heavy loads, have low bearing capacity, or experience issues like high water levels.
- Piles can be made of concrete, timber, steel, or composites, and are either pre-cast or poured in place. Common types include end bearing, friction, compaction, and anchor piles.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

- 1. Cast-in-situ Bored Pile by Dayanand Wandre B.E.Civil, PGDCM-Nicmar,MBA-Finance* Discover Engineering
- 2. Introduction • Pile foundations consist of piles that are dug into soil till a layer of stable soil is reached. • Pile foundations transfer building load to the bearing ground with the greater bearing capacity. • Pile foundations are useful in regions with unstable upper soil that may erode, or for large structures.
- 3. Displacement Pile (A/D) Advantage Disadvantages Pile material can be inspected for quality before driving May break during driving Construction operation affect by ground water Noise and vibration problems Can driven in very long lengths Cannot be driven in condition of low headroom Construction operation not affected by ground water Noise may prove unacceptable. Noise permit may be required Soil disposal is not necessary Vibration may prove unacceptable due to presence of sensitive structures, utility installation or machinery

- 5. Types of Pile • The pile installation procedure varies considerably, and has an important influence on the subsequent response • Three categories of piles are classified by method of installation as below: • Large displacement piles • They encompass all solid driven piles including precast concrete piles, steel or concrete tubes closed at the lower end • Small displacement piles • They include rolled steel sections such as H-pile and open-end tubular piles • Replacement piles • They are formed by machine boring, grabbing or hand-digging.
- 7. Precast pile
- 10. End Bearing Piles ROCK SOFT SOILPILES End bearing pile rests on a relative firm soil . The load of the structure is transmitted through the pile into this firm soil or rock because the base of the pile bears the load of the structure, this type of pile is called end bearing pile Most of the piles used in Hong Kong are end bearing piles. This is because the majority of new developments are on reclaimed land
- 11. SOFT SOILPILES Friction Piles If the firm soil is at a considerable depth, it may be very expensive to use end bearing piles. In such situations, the piles are driven through the penetrable soil for some distance. The piles transmit the load of structure to the penetrable soil by means of skin friction between the soil.
- 12. W Qu Qb Qs Qu = Qs + Qb - W Basic Concept The ultimate bearing capacity (Qu )of a pile may be assessed using soil mechanics principles. The capacity is assumed to be the sum of skin friction and end-bearing resistance, i.e Qu =Qb+Qs-W ……………………….(1) where Qu total pile resistance, Qb is the end bearing resistance and Qs is side friction resistance General behaviour Shaft resistance fully mobilized at small pile movement (<0.01D) Base resistance mobilized at large movement (0.1D)
- 13. Loading Settlement Behaviour of Frictional Pile Loading Settlement Behaviour of End Bearing Pile Qu QS QB Qu QB QS • Piles founded on strong stratum • Not much benefit in enhancing base resistance • Important to adopt good construction practice to enhance shaft friction • Shaft grouting useful in enhancing pile capacity Piles founded on dense soils Important to adopt good construction practice to enhance shaft friction and base resistance Shaft and base grouting useful in enhancing pile capacity
