Pile driving equipments_Advanced Construction Technology (Semester-6), Civil ...A Makwana
The ‘operation’ of inserting a pile into the ground is known as Pile driving.
Piles are driven into the ground by means of hammers.
The equipment used to lift the hammer and allow it to fall on the head of the pile is known as the ‘Pile Driver’.
Bridge bearings are used to transfer forces from the superstructure to the substructure while allowing movements. Traditional bearings included pin, roller, rocker, and sliding metal bearings. Pin bearings allow rotation but not translation. Roller bearings allow longitudinal movement and restrict lateral and rotational movement using gearing. Rocker and pin bearings are used in steel bridges as they accommodate both rotational and translational movements. Sliding bearings use low-friction materials like PTFE to allow translation. Modern bearings include pot, laminated elastomeric, lead-rubber, and plain elastomeric bearings. AASHTO guidelines provide criteria for selecting suitable bearings based on required movements and load resistances
This document provides information about pipe laying methods for underground pipes. It discusses both onshore and offshore pipe laying techniques. For onshore pipe laying, the key steps described are: 1) preparing detailed maps of the area, 2) marking the center line for the pipeline, 3) unloading and storing the pipes, 4) cutting pipes to length, 5) digging trenches, 6) lowering and connecting the pipes in the trenches, and 7) backfilling the trenches. Proper preparation, handling, installation, and backfilling of the pipes are important to avoid damage to the pipeline.

This document summarizes a seminar presentation on transmission line maintenance techniques in India. It provides an overview of extra high voltage alternating current (EHVAC) transmission line maintenance in India, including methods such as predictive maintenance using thermography and insulator testing, as well as preventive maintenance techniques including cold line maintenance (with the line de-energized) and live line maintenance (with the line energized). It describes some of the specific maintenance works that can be done using live line techniques, and discusses the advantages of live line maintenance.
Cross drainage works carry the flow of a natural stream crossing a canal. The main types are aqueducts, siphon aqueducts, super passages, and siphons. Aqueducts are used when the canal bed is above the drain flood level, allowing gravity flow. Siphon aqueducts are used when the drain flood level is above the canal bed, requiring siphonic action. Super passages are used when the drain bed is above the canal supply level, with the canal flowing under the drain. Siphons are used when the canal supply level is above the drain bed. The selection depends on the relative water levels and sizes of the canal and drain.

Track junctions transfer rail vehicles between tracks or allow them to cross tracks. There are several types of simple track layouts for junctions depending on traffic needs. Common layouts include turnouts that continue or change the direction of travel, symmetrical splits that divert tracks in two directions with equal radii, and three-throw switches that allow movement in three directions but are now obsolete due to safety concerns. More advanced layouts include double turnouts, diamond crossings, scissors crossovers, triangles, and double junctions.
Railway engineering involves the design, construction, and operation of railroads and mass transit systems. It is a branch of civil engineering that deals with track design, station layout, signaling systems, and train movement control. Typical tasks for railway engineers include determining horizontal and vertical alignment, estimating construction costs, and establishing signaling and control systems. Railway tracks consist of rails laid on sleepers embedded in ballast. Points and crossings allow trains to switch tracks. A variety of signals are used to safely direct train movement.

Rails, Types, Joints, Creep, Failure of Rails and Welding of Railssrinivas2036
The document discusses rails used in railway tracks. It defines different types of rails including double headed, bull headed, and flat footed rails. Flat footed rails, also called Vignoles rails, are now most commonly used. Standard rail sections used in Indian railways, such as 52kg and 60kg, are presented. Requirements of an ideal rail and factors affecting rail wear and failure are explained. Methods to reduce rail wear include use of special alloys, track maintenance, reducing expansion gaps, and lubricating rails.
The failure conditions can determine when and how to conduct an analysis. For example, if the gears are damaged but still able to function, the company may decide to continue their operation and monitor the rate at which damage progresses. In this case,
samples of the lubricant should be collected for analysis,
the reservoir drained and flushed and the lubricant replaced.
If gearbox reliability is crucial to the application, the gears should be examined by magnetic particle inspection to ensure that they have no cracks.
checking the gears for damage by visual inspection and by measuring sound and vibration. Analysis is carried out at different points in the engine.
Spillways are designed to safely pass excess water from a reservoir to prevent overtopping of a dam. They come in many forms depending on site conditions but commonly include an overflow structure like an ogee crest to control reservoir levels. Proper spillway capacity is essential for dam safety as inadequate capacity contributes to 40% of dam failures. Spillway design considers hydrologic factors, hydraulic performance including discharge coefficients, and structural aspects like cost-effectiveness. Gates may be added to overflows to allow flexible reservoir operation while preventing overtopping during floods.
Turnouts allow trains to change tracks and directions by using a combination of points and crossings. Points consist of movable tongue rails and stationary stock rails, while crossings connect intersecting tracks using wing rails and a V-shaped nose. There are two main types of turnouts - left-hand and right-hand - depending on the direction trains divert. Proper turnout design and components like check rails are important for train safety given they are weak points on the track. Different types of crossings exist depending on the angle of track intersection, including acute, obtuse, and square crossings.
Segmental bridge construction involves building bridges out of precast concrete segments. This allows for longer spans than traditional methods by reducing the need for intermediate piers. There are several techniques for segmental bridge construction including cast-in-place using form travelers, incremental launching where segments are cast and then pushed out over supports, and precast segment erection using launching girders. Segmental construction enables building bridges more quickly and over existing infrastructure with minimal traffic disruptions.

Bridge bearings are structural devices installed between bridge substructures and superstructures. They transfer loads while allowing for movement. There are two main types: expansion bearings, which allow translational and rotational movement, and fixed bearings, which allow limited translational and rotational movement. Common bearing types include sliding, rocker and pin, roller, elastomeric, curved, pot, and disk bearings. Each has distinct structures, materials, and abilities to accommodate different load types and movements. Regular inspection and maintenance are important due to risks of corrosion and damage over time.

Postmodernism (Foucault and Baudrillard)John Bradford
This document provides an overview of postmodernism and some of its key thinkers. It discusses:
- Postmodernism emerged as a critique of modernity and challenged ideas like universal truths, objective knowledge, and historical progress.
- Key postmodern thinkers included Derrida, Foucault, Lyotard, and Baudrillard. They analyzed how power shapes knowledge and questioned foundations of knowledge.
- Foucault argued that knowledge is a form of power and that what counts as truth is determined by prevailing power structures in society rather than objective facts. He analyzed how power operates in subtle ways through social institutions and practices.
