AI Technical Summary

Technical Problem

The length of the existing foundation pit protection device for construction is fixed, which is inconvenient to adjust, and the protective net needs to be replaced as a whole when it is damaged, resulting in a large loss.

Method used

A foundation pit protection component for municipal construction is designed, and a protective net structure with adjustable length is controlled. The expansion and storage of the protective net is controlled through the worm gear and worm transmission. Combined with a slidable bracket and limiting rod, the local replacement and shape adjustment of the protective net are realized.

Benefits of technology

It realizes flexible adjustment of the length of the protective net, and the mesh cover can be replaced separately when partially damaged, reducing the loss of overall replacement and improving the stability and fit of the protective net.

Abstract

The invention discloses a foundation pit protection assembly for municipal building construction, and relates to the technical field of building construction, the foundation pit protection assembly comprises two bases and limiting rods, the tops of the two bases are both provided with positioning sleeves, the interiors of the two positioning sleeves are slidably connected with a first support and a second support respectively, and a groove is formed in the first support. The foundation pit protection assembly for municipal building construction has the beneficial effects that the protection net is wound through the winding shaft in the support, the worm gear and the worm are matched, the protection net is controlled to be folded and unfolded by the corresponding length, the length of the protection net is conveniently adjusted according to the range of a foundation pit, meanwhile, the protection net is composed of the multiple net covers and fixed through the fixing ropes, and the protection net is convenient to use. When local damage occurs, a single protective net can be replaced, loss can be reduced, pressing plates in the limiting frames clamp the protective nets under the action of springs, the direction and shape of the protective nets can be conveniently changed, and the protective nets are more attached to a foundation pit and are more stable.
