Analysis of technical examination questions of underground continuous wall construction over the years

Construction technology of diaphragm wall is an important link in civil engineering, and joint management is the key. In order to help you better master the construction technology of underground continuous wall, the following is the analysis of real questions over the years.

The construction speed is fast and the technical requirements are high.

The main characteristics of cast-in-place reinforced concrete diaphragm wall are fast construction speed and relatively high technical requirements.

Optional wall materials

According to different use requirements and construction conditions, clay, concrete and reinforced concrete can be used as wall materials of underground continuous wall.

Multifunctional use

Cast-in-place diaphragm wall has many functions, such as bearing, seepage prevention, retaining soil, deep foundation pit support and so on.

The joint quality is difficult to control.

The disadvantages of underground continuous wall include that the joint quality between continuous walls is difficult to control, the pulping treatment system occupies a large area and is easy to cause pollution, and the construction technology requirements are high.
