A foundation pit enclosure device for road construction

Abstract

The invention discloses a foundation pit enclosure device for road construction, which comprises a cement column, a symmetrically arranged combined maintenance component, a supporting force application component and a number of expansion bolts, the combined maintenance component and the side wall of the foundation pit A foundation pit slope protection assembly is arranged between, and the foundation pit slope protection assembly includes a transition support maintenance plate, an elastic plate and a connecting structure assembly, and a limit assembly is arranged between the transition support maintenance plate and the side wall of the foundation pit; The support maintenance plate and the elastic plate are connected through the drive rod threaded with the transition support maintenance plate and the transition drive plate rotatably installed with the installation seat, that is, the drive installation seat and the elastic plate are extruded toward the side wall of the foundation pit, and the drive rod and the transition The inclination angle of the elastic plate can be adjusted under the action of the mutual hinge of the driving plates, and the elastic plate is driven to fit on the side wall of the foundation pit, so as to realize the purpose of slope protection on the side wall of the foundation pit and prevent the soil and stones on the side wall of the foundation pit from falling fall and improve the effect of foundation pit enclosure.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a foundation pit enclosure device for road construction. Background technique [0002] The pit body is a method for developing and utilizing underground space, building multi-storey basements, underground railways, underground commercial streets and other underground buildings. The pit body enclosure is to prevent the pit body from collapsing. It mainly includes gravity mixing pile retaining walls, Underground diaphragm wall, pile retaining wall, etc., the pit enclosure can not only ensure the stability of the pit body and the safety and convenience of the operation in the pit, but also control the displacement of the soil at the bottom of the pit and outside the pit within a certain range to ensure The normal use of adjacent buildings and municipal facilities is of great significance. [0003] The maintenance baffles in the existing foundation pit enclosures used for road const...

AI Technical Summary

Problems solved by technology

[0003] The maintenance baffles in the existing foundation pit enclosures used for road construction are all rigid and vertical, facing the uneven side walls of the foundation pit, there will be gaps between the maintenance baffles and the side walls of the foundation pit, and the side walls of the foundation pit Soil, stones, etc. may fall, resulting in the instability of the maintenance baffle, and poor foundation pit enclosure effect. Based on this, we propose a foundation pit enclosure device for road construction to solve the above problems
