AI Technical Summary

Technical Problem

Existing foundation pit support systems are unable to adapt to changes in the size and pressure of different foundation pits, resulting in tilting and deformation within the foundation pit, leading to a high risk of accidents, and the retaining plate does not fit well with the side wall of the foundation pit.

Method used

An adjustable pit sidewall support system is adopted, including retaining plates, transverse support rods, and detailed adjustment rods. The length of the support rods and the fit of the retaining plates are achieved through threaded connections and deformable layers. An elastic sponge layer is used to fill depressions and accommodate protrusions.

Benefits of technology

It improved the fit between the retaining plate and the sidewall of the foundation pit, reduced the tilting and deformation of the foundation pit, lowered the risk of accidents, and enhanced the adaptability and stability of the support system.

Abstract

The utility model discloses an adjustable foundation pit side wall supporting system which comprises soil retaining plates and a transverse supporting rod arranged between the soil retaining plates, a detail adjusting rod is arranged at the end of the transverse supporting rod, the adjustable supporting rod abuts against the soil retaining plates, and a deformable layer is arranged on the side, facing the side wall of a foundation pit, of each soil retaining plate. The distance between the breast boards is adjusted in a double-adjustment mode through the detail adjusting rods at the ends of the transverse supporting rods, and the fitting degree of the breast boards and the foundation pit is improved; the deformable layer is used for filling and containing the pits and the protrusions of the side wall of the foundation pit.
