Abstract

The invention relates to the technical field of buildings, and discloses a foundation pit supporting structure and a construction method thereof.The foundation pit supporting structure comprises a first supporting assembly used for supporting the side wall of a foundation pit, and the first supporting assembly is provided with a first grouting cavity; the second supporting assembly is arranged on the side, away from the side wall, of the first supporting assembly, and the second supporting assembly is provided with a second grouting cavity; the grouting assembly is arranged between the first supporting assembly and the second supporting assembly, the grouting assembly is provided with a grouting pipeline and a grout inlet, the first grouting cavity communicates with the second grouting cavity, and the grouting pipeline, the first grouting cavity and the second grouting cavity can be filled with grouting materials by pouring the grouting materials into the grout inlet; and the first supporting assembly, the second supporting assembly and the grouting assembly are connected through the solidified grouting material. According to the foundation pit supporting structure and the construction method thereof, the probability of deformation of the foundation pit supporting structure can be reduced.

本申请涉及建筑技术领域，公开了一种基坑支护结构及其施工方法，基坑支护结构包括：第一支撑组件，用于对基坑的侧壁进行支护，第一支撑组件设置有第一注浆腔体；第二支撑组件，设于第一支撑组件背离侧壁的一侧，第二支撑组件设置有第二注浆腔体；注浆组件，设于第一支撑组件与第二支撑组件之间，注浆组件设有注浆管路和进浆口，第一注浆腔体与第二注浆腔体相连通，通过往进浆口内灌注灌浆料，可使得灌浆料填充注浆管路、第一注浆腔体和第二注浆腔体，并使得第一支撑组件、第二支撑组件和注浆组件通过凝固后的灌浆料相连接。本申请提供的基坑支护结构及其施工方法，能够降低基坑支护结构发生变形的几率。
