Retaining wall is a structure that holds back the soil or stone from a building, structure or area. The retaining walls of movement or downslope, prevents erosion and provides support for vertical or almost vertical. Cofferdams and bulkheads, structures that hold water, are sometimes also thought of as retaining walls. Retaining walls are generally made of stone, stone, brick, concrete, vinyl, steel or wood. Once popular as an inexpensive retaining material, rails have fallen out of use due to environmental concerns.
Retaining wall construction is one type of civil construction that serves to withstand the lateral active force pressure of a soil or water. Therefore a retaining wall construction must be planned and designed to be safe against forces that could potentially lead to structural failure. In principle, the retaining wall receives forces in the form of bolsters, own gravity, passive-active / passive ground / water force, sliding / sliding force and uplift. Thus, the stability of a retaining wall construction must be designed so as to resist such forces.
Retaining walls in civil construction practice have many types depending on the application and cases to be used either to withstand soil pressure on slope, embankment, sub structure / basement construction, retention / pond retention basin, water-repellent construction, sediment transport levers on the river and so on. Basically the retaining wall has several functions, among others:
- Hold active lateral lung pressure (Active Lateral Force Soil) which can potentially cause lateral collapse of the soil eg landslide / landslide.
- Resisting water lateral pressure (Lateral Force Water) which can potentially lead to lateral collapse due to large water pressures.
- Prevent the occurrence of seepage water seepage laterally caused by high ground water level conditions. In this case also functions in the dewatering process by cutting the flow of water (Flow net) on the ground (Cut Off).
A wall, either stand-alone or sideways reinforcing, to counter the change of soil or surface and reject other forces of matter in contact with the side of the wall, thus preventing the mass from shifting to lower altitudes
A generic structure used to resist vertically or almost vertically the ground surface. The retaining walls must withstand lateral ground pressure, which tends to cause the structure to slide or reverse.
Retaining Wall Progress
Retaining Wall is a retaining wall located on the side edge. The work of making the retaining wall begins with the installation of the necessary reinforcement. The reinforcement used is a conventional reinforcement mounted in place one by one. After the installation of the reinforcement is completed, then followed by installation of bekistingshear wall and concrete casting. Foundry done gradually, not done from bases – 4 to the ground surface at once, but done per floor.
Casting for one part is done at once by using Pouring Bucket and Crane Tow. After the concrete is poured then held compacting by using concrete vibrator. Formwork then opened the fastest after 2 days.
