Problems solved by technology

[0004] However, the existing support structure for deep foundation pit anti-collapse has simple structure, single function, and manual construction is generally used for installation, which cannot meet the needs of modern and rapid construction. In view of this, we propose a deep foundation pit anti-collapse structure

Abstract

The invention discloses a deep foundation pit anti-collapse structure and belongs to the technical field of cross-sea passage construction. The deep foundation pit anti-collapse structure comprises asupporting panel. By forming a soil heaping groove with a wavy structure in the section of the front side of the supporting panel, the deep foundation pit anti-collapse structure is beneficial for increasing the friction force with a protection slope to prevent the protection slope from collapsing to cause landslide; according to the deep foundation pit anti-collapse structure, two mounting grooves are also symmetrically formed in the end parts of the two sides of the supporting panel, linking mechanisms are arranged in the mounting grooves, outrigger components are driven by hand wheel components in the linking mechanisms to extend to be inserted in the ground, and the outrigger components can also be closely inserted in the ground under buffering effects of buffering rods even though theground is uneven; and meanwhile, the outrigger components drive diagonal bracing components to be opened in the extending process so that the diagonal bracing components are conveniently connected and fixed to a ground pile. The deep foundation pit anti-collapse structure has the advantages that the structural design is reasonable, the mounting is simple and convenient, the labor intensity of workers is reduced and the mounting efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of sea-crossing channel construction, and more specifically relates to a deep foundation pit anti-collapse structure. Background technique [0002] While deep foundation pits provide a reliable foundation for the construction of cross-sea passages, they are very prone to landslides: landslides not only cause instability and structural deformation of surrounding buildings, but also cause casualties of construction personnel and damage accidents to mechanical equipment. Construction safety brings great hidden dangers. Once a landslide occurs, cleaning the landslide site will lead to a delay in the construction period and an increase in engineering costs, which will have a very adverse impact on the project. Therefore, how to effectively prevent landslides has become an urgent issue for construction units. [0003] At present, in order to avoid the collapse of deep foundation pits, the following points are ma...
