Slope retaining wall for hydraulic and hydroelectric engineering

Technical Field

The application relates to the field of retaining walls, in particular to a slope retaining wall for hydraulic and hydroelectric engineering.

Background

The hydraulic and hydroelectric engineering is a key national construction project which is beneficial to people and economical, the slope problem is one of outstanding questions in the hydraulic and hydroelectric engineering construction process, and the slope is various, so that the processing factors and the required technology are more, and certain complexity is realized. The safety of the slope of the hydraulic and hydroelectric engineering needs to be paid sufficient attention, because the slope is closely related to the quality and safety of the hydraulic and hydroelectric engineering and the life and property safety of an engineering area and downstream people, if the problem of the slope is not properly treated, the slope is likely to damage the surrounding environment, so that a greater disaster is caused, and therefore the slope design and the safety are intuitively important.

The retaining wall is a structure for supporting roadbed filling or hillside soil and preventing the filling or soil from deforming and destabilizing. According to different rigidity and displacement modes, the retaining wall can be divided into three types, namely a rigid retaining wall, a flexible retaining wall and a temporary support. In the cross section of the retaining wall, the part which is directly contacted with the supported soil body is called a wall back; the part facing the wall back and being empty is called the wall surface; the part directly contacting with the foundation is called a substrate; the top surface of the wall opposite the base is called the wall top. In the process of water conservancy and hydropower construction, retaining wall construction is one of the most important steps.

With respect to the related art in the above, the inventors consider that there are the following drawbacks: in the existing slope construction process, in the existing retaining wall construction process, more groups of stones are built on the retaining wall by means of concrete, and the stones of all groups are built along the slope surface of the slope from bottom to top; after the retaining wall construction is completed, due to reasons such as rainfall, the water flow on the ground continuously erodes the ground, so the drift sand phenomenon easily appears on the ground of one side of the retaining wall departing from the side slope, and then the foundation part of the retaining wall is unstable, and the retaining wall has the potential threat of slumping at the moment, so the improved space exists.
