AI Technical Summary

Technical Problem

The existing modular flood control retaining wall cannot adjust its sealing strips according to deformation under water pressure load, resulting in sealing failure, water leakage, and in severe cases, the retaining wall may collapse.

Method used

The system employs a pressure-bearing mechanism and an airbag. When the rubber layer deforms, the air inside the pressure chamber pushes the airbag to expand into the sealing groove, achieving self-adaptive sealing and compensating for gap changes caused by insufficient rigidity. The locking mechanism ensures stable connection of the retaining wall through wedge blocks and wedge grooves.

Benefits of technology

It improves the sealing effect, prevents water leakage, enhances the stability of the retaining wall, reduces disassembly difficulties and the risk of sealing strip aging, and adapts to problems such as structural assembly deviations and insufficient production precision.

Abstract

The application belongs to the technical field of flood prevention, and discloses a modular assembled flood prevention retaining wall device, which comprises a retaining wall in the shape of "L" and hollow.The application is characterized in that a pressure bearing mechanism and an air bag are arranged in cooperation, water flow impact on the pressure bearing cabin makes the rubber layer deform, the air inside the pressure bearing cabin pushes the air bag to expand outward into the sealing groove, sealing is realized, and the response speed of the air bag is improved, that is, the greater the water pressure, the greater the force with which the air inside the pressure bearing cabin pushes the air bag to expand outward, and the better the sealing effect, since the air bag is soft as a whole, it can fill the sealing groove more completely, the poor sealing effect of the round corner part of the retaining wall is avoided, the problem of structural assembly deviation or insufficient production precision is adaptively compensated, irregular gaps generated after the deformation of the retaining wall due to water pressure can be filled, the defect that the traditional sealing rubber strip cannot adjust with the change of the gap due to insufficient rigidity is compensated, and the continuous adhesion of the sealing interface is maintained.
