Abstract

The invention discloses a supporting method for a foundation pit excavation project. The supporting method comprises the following steps: constructing supporting piles around a to-be-excavated foundation pit; constructing a capping beam on each supporting pile; performing slope excavation on a soil body to form a center island area of the foundation pit and a side slope area between the center island area and the supporting piles; constructing a center concrete bottom plate in the center island area; constructing a concrete soil supporting pier on the center concrete bottom plate; erecting an inclined brace along the slope surface of the side slope area, and anchoring the two ends of the inclined brace on the concrete supporting pier and the capping beam respectively; excavating earthworks in the side slope area to be flush with the center island area, manufacturing an L-shaped support replacement plate on the bottom surface of the side slope area after excavation, supporting a horizontal section of the L-shaped support replacement plate on the center concrete bottom plate, and supporting a vertical section of the L-shaped support replacement plate on the supporting piles; and when the L-shaped support replacement plate reaches designed strength, removing the inclined brace to finish the construction. According to the supporting method disclosed by the invention, multiple times of concrete constructions are avoided, the L-shaped support replacement plate and the supporting piles form a fence for water and soil pressure of the foundation pit in a later period, and the construction period is saved.

Description

technical field [0001] The invention relates to the field of foundation pit excavation construction, in particular to a support method for foundation pit excavation engineering. Background technique [0002] Foundation pit engineering has the characteristics of large engineering volume, high technical difficulty, and many unforeseen factors. The safety and reliability of foundation pit support not only affects the foundation pit project itself, but also often affects the surrounding environment of the foundation pit. Because of this, the foundation pit support scheme must be selected in consideration of the surrounding environment; on the other hand, although the foundation pit support is a temporary structure, its cost is very high, and its impact on the total project cost cannot be ignored. Therefore, how to choose the foundation pit support form that can not only protect the environment but also be economical and reasonable has very important practical significance. [0...
