Problems solved by technology

This type of method has two major disadvantages. First, the construction efficiency of the full house scaffolding system is low, and the transfer speed of the working face is slow. In the downtown area, or near the operation of the subway, the demolition of the temporary support structure must ensure

Abstract

The invention relates to a deep foundation pit support dismounting system. The deep foundation pit support dismounting system comprises a protective frame system, a sliding carrying support bracket system, an inner support steel tube stand column dismounting system and a frame column safety protective system, wherein the protective frame system comprises an integral type frame bottom plate, a scaffold support and tool type guard bars; the scaffold support is erected on the integral type frame bottom plate, and a section bar reinforcing top plate is arranged on the top of the scaffold support;split heads and lifting jacks are symmetrically distributed on the section bar reinforcing top plate; the tool type guard bars are mounted at the two sides of the section bar reinforcing top plate; the sliding carrying support bracket system comprises a horizontal moving slide plate, a traction system and a lifting system; a slide rail is arranged on the section bar reinforcing top plate; the horizontal moving slide plate with a slide wheel is mounted on the slide rail; and a dismounted supporting beam is arranged on the horizontal moving slide plate. The deep foundation pit support dismounting system has the beneficial effects that: foundation pit support dismounting adopts the integral lifting type protective frame system, the supporting beam slowly drops through the lifting jacks, the combined tool type guard bars replace the conventional supporting protective structure, and construction is safe and efficient.

Description

technical field [0001] The invention relates to a deep foundation pit support removal system and construction method, which belongs to the field of foundation and foundation engineering, and is suitable for foundation pit support removal construction, especially suitable for complex environmental conditions such as urban downtown areas and surrounding building-intensive areas. The horizontal temporary support system of the deep foundation pit was removed. Background technique [0002] With the acceleration of urbanization in my country, urban buildings present a trend of super-high and super-deep development, which puts forward higher requirements for the construction of deep foundation pits. The complexity of the surrounding environment of urban buildings makes foundation pit anchors The use of the protection system is limited, and the support system of "support pile or continuous wall + internal support" has been replaced by it, which has been widely used in recent years, e...
