Support changing component capable of applying prestress and supporting method thereof
The invention discloses a support changing component capable of applying prestress and a supporting method thereof, and aims to provide the support changing component capable of applying prestress and the supporting method thereof, which can apply prestress to a foundation pit enclosure wall in the process of removing a foundation pit support so as to reduce foundation pit deformation caused by removing the foundation pit support. A support changing component capable of applying prestress comprises a counter-force component, a supporting component, a supporting component and a supporting component, the counter-force component is fixed to a foundation pit bottom plate, and the counter-force component is close to a foundation pit enclosure wall; and the axial force applying component is located between the foundation pit enclosure wall and the counter-force component, and the axial force applying component is used for applying prestress to the foundation pit enclosure wall in the process of dismantling the horizontal support of the foundation pit.
本发明公开了一种可施加预应力的换撑构件及其支撑方法，旨在提供一种能够在基坑支撑拆除的过程中，对基坑围护墙施加预应力，以减小因基坑支撑拆除而发生的基坑形变的可施加预应力的换撑构件及其支撑方法。一种可施加预应力的换撑构件，包括：反力构件,反力构件固定在基坑底板上，且反力构件靠近基坑围护墙；轴力施加构件，轴力施加构件位于基坑围护墙与反力构件之间，轴力施加构件在基坑的水平支撑拆除的过程中，用于对基坑围护墙施加预应力。
