Foundation pit water filter screen supporting system

Abstract

The invention discloses a foundation pit water filter screen supporting system. The system comprises a support, the support is of a hollow rectangular structure with an opening in one end, a circle ofprotective edge is arranged on the outer wall of the opening of the support, and the protective edge and the support are integrally formed and cast. A pressing plate is arranged in the support, at least one limiting mechanism is arranged on the inner wall of the support and used for limiting the pressing plate to only achieve linear motion, and a telescopic mechanism is arranged between the pressing plate and the inner wall of the support and used for driving the pressing plate to conduct linear motion. An elastic reset piece is arranged between the pressing plate and the inner wall of the support and used for driving the pressing plate to be retracted into the support under the condition that no external force exists. By arranging the telescopic mechanism, the pressing plate is uniformlypushed to move through the movement of the two ejector rods in each group, and the ejector rods are uniformly distributed, so that the pressing plate is uniformly stressed and can be better used forsupporting a water filter screen.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a support system for foundation pit water filtering nets. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size. In the prior art, soil nail walls are generally used to support foundation pits. In the process of digging foundation pits, water gushing and sand gushing are often encountered. In this case, if you continue to use soil nail walls for support, you need to dig a certain depth. However, in the actual process of digging , It will cause the side wall of the foundation pit to collapse, and in severe cases, the side wall of the entire foundation pit will collapse, affecting the ground buildings and other situations. Therefore, there is a water filter device for blocking sand and water gushing on the market. [0003] The patent notification number is C...

AI Technical Summary

Problems solved by technology

There are four layers of supporting mesh, starting from the side close to the foundation pit wall, followed by geotextile, steel mesh, steel mesh and steel mesh, which can play a good role in filtering water, but the fixing of the supporting mesh is usually It is fixed by the anchor rods around it, but the middle part is not fixed. Under the weight of the steel mesh, it is easy to make the geotextile and steel mesh fall down, thus losing the supporting effect and causing the side wall to collapse
