Introduction to cutting retaining wall?

What is a cutting retaining wall? What is the basic situation of cutting retaining wall? The basic contents of cutting retaining wall compiled by Bian Xiaozhongda Consulting Company are as follows:

Based on the knowledge of architectural knowledge column of this website, Zhong Da consulted and sorted out the basic situation of cutting retaining wall as follows:

Retaining wall refers to the structure that supports subgrade fill or hillside soil to prevent deformation and instability of fill or soil.

Retaining walls are divided into filling embankment retaining walls (shoulder walls or embankment walls) and cutting retaining walls.

At present, the common forms of cutting retaining wall are: gravity retaining wall.

Gravity retaining wall relies on its own gravity to maintain the stability of retaining wall under the action of earth pressure. It is a common retaining wall in China at present. Gravity retaining wall can be made of stone or concrete, and it is generally made into a simple trapezoid.

Gravity retaining wall refers to the retaining wall that relies on the self-weight of the wall to resist the lateral pressure of the soil. Gravitational retaining wall can be made of rubble, flaky and precast concrete blocks, or flaky concrete and concrete can be poured as a whole. Semi-gravity retaining wall can be poured with concrete or less reinforced concrete. Gravity retaining wall can be made of stone or concrete, and it is generally made into a simple trapezoid. Its advantages are local materials, convenient construction and good economic effect. Therefore, gravity retaining wall is widely used in railway, highway, water conservancy, port, mine and other projects in China.

Scope of application of cutting retaining wall:

(1) The cutting excavation is deep and the hillside is steep, which is used to reduce the height of the slope, reduce the excavation of the hillside and avoid destroying the mountain balance.

(2) Using unfavorable geological conditions to support the slope soil or broken rock stratum that may collapse.

(3) In order to avoid disturbing other buildings (such as houses, railways, canals, etc.). ) or prevent occupation of farmland.

(4) Prevent the dikes along the river from being washed and washed by water.

(5) Prevent the steep slope embankment from sliding.

(6) For embankments with high embankment filling height or steep slope, in order to reduce earthwork, demolition and land occupation, the toe of the slope must be restrained.

When considering the design scheme of retaining wall, technical and economic comparison should be made with other schemes. For example, when embankment or shoulder retaining wall is used, it is often compared with trestle or fill. When cutting or hillside retaining wall is used, it is often compared with tunnel, open hole or brush slope to make the engineering technology economical and reasonable.
