Dewatering
Dewatering involves controlling groundwater by pumping, to locally lower groundwater levels in the vicinity of the excavation. The simplest form of dewatering is sump pumping, where groundwater is allowed to enter the excavation where it is then collected in a sump and pumped away by robust solids handling pumps.
Dewatering methods for excavations at construction sites
The document discusses four main methods for dewatering excavations at construction sites:
1. The wellpoint method uses a series of wells and pumps to lower the water table up to 5-6 meters below the wells.
2. The eductor wells method is similar but uses high pressure water and venturi tubes instead of vacuum pumps to draw water from the wells.
3. Open sump pumping relies on gravity, using sumps or ditches to collect water for removal by pumps.
4. The deep well method uses deeper wells 150-200mm in diameter surrounded by casings and screens to draw water down by up to 30 meters.
Earth Compaction Equipment
This document summarizes the main types of earth compaction equipment, including smooth-drum vibratory rollers, tamping rollers, sheep foot rollers, pad-drum vibratory rollers, and pneumatic-tyred rollers. It provides details on the characteristics of each type, such as their weight, speed, effectiveness on different soil types, and how they compact the earth through vibratory action, kneading action of pads or feet, or varying tire pressure. The document aims to inform readers about the different compaction equipment used for tasks like compacting embankments, canals, and trenches.
Heavy earth moving machinary
The document discusses Heavy Earth Moving Machinery (HEMM) and Bucket Wheel Excavators (BWE). It provides information on:
1) HEMM are large machines used for excavation and material handling in mining, construction, and other industries. They include excavators, dozers, loaders, and dump trucks.
2) BWE are continuous excavation machines with multiple buckets on a rotating wheel that dig, lift, and convey material onto belts for transport.
3) BWE are well-suited for large-scale, open-pit excavation where conditions allow for continuous operation.

The document describes different types of excavation machines, including power shovels, draglines, hoes, clam shells, and trenching machines. Power shovels can excavate all soil types except hard rock and vary in size from 0.5 to 5 cubic meters. Draglines can excavate below their track level and handle softer materials over larger distances than power shovels. Hoes are used to excavate below the machine's surface. Clam shells have two hinged shells used to lift materials vertically. Trenching machines can excavate trenches for utilities and services in soils except rock. Machine type selection depends on the job requirements and site conditions.
De watering-ppt
The document discusses different methods for dewatering construction sites. Dewatering involves removing water from a construction site by lowering the water table. This provides a dry working area, which is often required by codes. It also prevents problems from subsurface water, like flooding or excess humidity. Common dewatering methods include ditches and sumps, well point systems, shallow and deep well systems, and the vacuum method. Temporary methods lower the water table during construction, while permanent exclusion uses impermeable barriers to block future water flow. Specific temporary methods discussed are simple sump pumping, jetted sumps, and well point systems.

Openpitmining
Open-pit mines are used when commercially useful minerals or rock deposits are near the surface and overburden is thin, as they are more economical than tunnel mining. Ore is extracted from successive vertical benches in the open pit until resources are depleted or overburden costs rise. Exhausted open pits are sometimes converted to landfills but may require water control to prevent flooding and formation of lakes.
In pit crusher conveyour system
This document discusses an in-pit crusher conveyor system used at an open pit coal mine. It describes the system as using a semi-mobile crushing plant that can be periodically relocated as mining progresses. The crushed material is then transported out of the pit using belt conveyors. Maintaining and relocating the semi-mobile crushing plant every 1-2 years helps minimize truck haulage distances and costs within the open pit mine.
Types Of Roller Used For Construction
The document discusses three main types of earth compaction equipment: smooth wheel rollers, sheep foot rollers, and pneumatic-tyred rollers. Smooth wheel rollers are used for ordinary compaction and weigh 5-15 tonnes. Sheep foot rollers are best for deep compaction of clay soils, can weigh over 15 tonnes, and have feet that knead the soil layers. Pneumatic-tyred rollers are most suitable for fine-grained soils and control ground contact pressure through wheel weight and width adjustments.
Dewatering
This document discusses three types of dewatering systems:
1. Open dewatering systems utilize sumps along excavation slopes and centrifugal pumps to directly remove groundwater. They are easy to install and operate.
2. Well point dewatering systems lower groundwater levels for large construction sites using well points installed along trenches, connected to headers and pumped by gravity or vacuum.
3. Deep well dewatering systems lower groundwater to considerable depths using submersible pumps in wells over 150mm in diameter, with discharge pipes connected to a common line.
Raod side ditches

Dredging
1. Dredging involves digging and removing material from water bodies like harbors, channels, and lakes to deepen them or maintain their depth. It is done for purposes like navigation, construction, environmental remediation, and more.
2. There are two main types of dredging: mechanical dredging which uses buckets and grabs, and hydraulic dredging which uses pumps to remove material in liquid form. Each has their own advantages and limitations.
3. Dredged material must be properly managed through beneficial reuse, confined disposal, treatment if contaminated, or open water disposal if suitable. Large dredging projects can impact the environment so careful planning and assessment is important.

Armoured Ford - Low Water Stream Crossing
Armoured Ford / Armoured Ford / Low Water Stream Crossing
An alternative to constructing a bridge. Historically used since the beginning of mankind to cross a waterway. Bridges allow passage at all heights of water flows, but the cost and environmental impact of bridges with their abutments and approach causeways can be detrimental, liable to damage, loss of usage for a long period, expensive to build, expensive to maintain, expensive to replace as they come to the end of their service life and do not able to be upgraded to handle wider or heavier traffic.
Benefits: a) short construction time b) much lower cost than a bridge
Description: During normal stream low flows the water crossing is passable to vehicles and pedestrians. At periodic high flows vehicle passage is halted until water level drops(ie after a storm event).
Endurance: The lack of stream restriction (such as bridge abutments and built up approaches) allows the high flows to pass without costly damage to the crossing structure such as bridge failure. High-water flows that carry debris such as trees that get hung up on bridges due to lack of height clearance are not impeded with the use of an armoured ford.
Higher water volume streams: A modified armoured ford can handle larger normal water flows by the installation of one or a number of pipes underneath the armoured ford.
Durability: The usage of geotextile underlayment and articulated concrete block allow for differential movements that cause premature destruction and failure of poured concrete or cemented ford structures.
Modifiable: In the event that road usage changes such as wider vehicles or heavier loads or upgrading from one lane to two lanes is desired, the present armoured ford is able to be cheaply and quickly added to or re-built to accommodate.
Longetivety: Armoured fords built by the Romans 2,000 yrs ago are still in user today.
Environmental: A very low environmental impact compared to excavation and construction of abutments and building up of bridge approach causeways.

Gas agency management system project report.pdf
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.

Advanced control scheme of doubly fed induction generator for wind turbine us...
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.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

- 16. 16 Large woody debris Kaiser X5 M Sloping back of the headscarp
- 17. 17 Caution Need good understanding of soils, water and slope processes
- 18. 18 Part 3 - Multiflow Drainpipe
- 19. 19 Multiflow pipe Available in 15,30 & 46 cm widths Made up of multiple miniature “Big O” pipes laid flat, joined together and covered in a filter fabric A viable alternative for Drain rock
- 20. 20 Part 4 - Contour Drainage
- 21. 21 This site is located in the Cariboo Mountains where a “hanging glacial” valley slopes into a typical “U shaped glacial valley”. Glacial fluvial out-wash deposits are buried below glacial till, resulting in seepage related slope instability problems.
- 22. 22 Road cut-slope. Tension crack showing evidence of slope ilure, along with visible evidence of retrogression of the headscarp. This site has been a an ongoing maintenance problem, with some restriction of road use. Tension crack – indicator of slope failure
- 23. 23 The Spider Excavator digs a trench above the crest of the headscarp and behind the tension crack. The trench is 3m in depth with the objective to interrupt the sub-surface water flows. he base of the trench should lope at least 2% towards an utlet end of the drainage.
- 24. 24 he multiflow drainage composite was put to the bottom of the trench, against the uphill ope, and a 6 mil polyethylene sheet placed ainst the down slope side for an impervious arrier. l placement was done from the surface. Workers re not permitted to enter the trench. e Multiflow pipe was attached to the poly and wered into the trench from the surface.
- 25. 25 The multiflow drainage composite was put into the bottom of the trench, against the uphill slope, and a 6 mil polyethylene sheet against the down slope side. Excavator starts backfilling the trench. Woody debris is then scattered over top Alternatively a composite “Blanket Drain” material such as Nudrain DM50 could be employed
- 26. 26 Excavator starts backfilling the trench. Woody debris is then scattered over top
- 27. 27 Steady seepage from subsurface drainage collector (Multiflow) 5 liters/min X 60 min/hr X 24 hrs day = 7200 liters/day That’s over 7000 kg less weight within the slope on a day to day basis! What difference does a month or two make?
- 28. 28 inished swale above head scarp with debris scattered over top. wale directs surface water away from problem area. (Picture has been stretched to emphasize the swale)
