In geotechnical engineering, a tieback is a structural element installed in soil or rock to transfer applied tensile load into the ground. Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles , sheet piles, secant and tangent walls) to provide ...
The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...
A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
A revetment in stream restoration, river engineering or coastal engineering is a facing of impact-resistant material (such as stone, concrete, sandbags, or wooden piles) applied to a bank or wall in order to absorb the energy of incoming water and protect it from erosion. River or coastal revetments are usually built to preserve the existing ...
A slurry wall is a civil engineering technique used to build reinforced concrete walls in areas of soft earth close to open water, or with a high groundwater table. [1] This technique is typically used to build diaphragm (water-blocking) walls surrounding tunnels and open cuts, and to lay foundations .
Return wing walls: used where banks are high and hard or firm. Their top width is 1.5 m and face is vertical and back battered 1 in 4. [ 2 ] Scour can be a problem for wing walls and abutments both, as the water in the stream erodes the supporting soil.
The practice of retainage dates back to the construction of the United Kingdom railway system in the 1840s. [2] [3]: 32 The size of the railway project increased demand for contractors, which led to the entrance of new contractors into the labor market. [2]
