Self-stabilizing assembly type supporting structure and construction method thereof
The embodiment of the invention discloses a self-stabilizing assembly type supporting structure and a construction method thereof. The self-stabilizing assembly type supporting structure comprises a supporting system of a cement soil wall and is characterized in that transverse profile steel is spliced at the bottom of vertical profile steel to form an inverted-T-shaped combined structure, and the inverted-T-shaped combined structure is welded and fixed through oblique steel. The cement soil wall is a foundation pit supporting wall, and the supporting system is of a cement soil wall inserted combined profile steel structure. The construction method of the structure comprises the construction steps of cement soil wall construction, profile steel combined structure splicing, wall bottom construction of high-pressure jet grouting piles, insertion of the profile steel combined structure, 90-degree rotation and the like. The structure has good self-stabilizing capacity, the phenomena that displacement of soil at the bottom of a foundation pit is too large, and a retaining wall is damaged due to kicking can be effectively prevented, and the overall safety of the foundation pit is guaranteed.
本发明实施例公开了一种自稳装配式支护结构及其施工方法，包括水泥土墙的支护体系，其特点是横向型钢拼接在竖向型钢底部，形成一种“⊥”型组合结构，并用斜向钢焊接固定。水泥土墙为基坑支护墙，支护体系为水泥土墙内插组合型钢结构。该结构施工包括水泥土墙施工、型钢组合结构拼装、墙底施工高压旋喷桩、插入型钢组合结构并旋转90°等施工步骤。本结构具有良好的自稳能力，能有效防止基坑底部土体位移过大，围护墙发生踢脚破坏的现象，保证了基坑整体安全。
