Foundation pit side slope supporting structure

Abstract

The invention discloses a foundation pit side slope supporting structure and belongs to the technical field of foundation pit supporting structures. The foundation pit slope supporting structure is mainly technically characterized by comprising a cover plate arranged on the outer side slope of a foundation pit, wherein the end, far away from the foundation pit, of the cover plate is fixedly connected with an outer baffle inserted into a foundation pit slope soil layer, the other end of the cover plate is connected with an inner guard plate attached to the inner wall of the foundation pit, a fixing piece is fixedly connected between the inner guard plate and the inner wall of the foundation pit, the side, far away from the foundation pit, of the inner guard plate is provided with a water guide groove, the water guide groove is connected with an underground water channel, and a water pumping assembly which is connected with the foundation pit and the water guide groove is arranged in thefoundation pit. By adopting the scheme, the cover plate is pressed and attached to the surface of the foundation pit slope under the fixing action of the inner guard plate and the outer baffle with the two ends inserted into the soil layer, so that the slope soil layer is effectively prevented from slipping, meanwhile, the soil layer can be shielded in rainwater weather, and the soil layer is prevented from collapsing due to excessive wetting.

Description

technical field [0001] The invention relates to the technical field of foundation pit supporting structures, in particular to a foundation pit slope supporting structure. Background technique [0002] Urban construction usually involves a large number of foundation pit projects. Whether it is a high-rise building or a deep foundation pit project for the subway, most of them are located in the prosperous areas of the city. The surrounding facilities are relatively mature. The road construction is basically in place, and the construction cannot cause damage to the surrounding buildings; The reserved space in the area is small, the geological environment is complex, the construction of deep foundation pits is limited, and the construction quality control, safety assurance, and organization are difficult. Because the foundation pit support is generally a temporary measure, the safety reserve of the support structure is small. The risks are also high. The economic indicators of t...

Problems solved by technology

However, in the foundation pit engineering in soft soil areas, the slope is prone to slide and become unstable when it encounters water. The traditional support structure is difficult to prevent the slope from sliding, especially the top soil, which brings serious safety hazards to the foundation pit engineering.
