Movable foundation pit support and underground structure construction method

HUANG XIACHEN / ZHANG JIE / QIU CHANGQING

The invention relates to a movable foundation pit support and an underground structure construction method.The movable foundation pit support comprises a track, movable seats and a steel structure support, the track is arranged on fender posts of a foundation pit, the movable seats are arranged at the two ends of the steel structure support and movably arranged on the track, brake pieces are arranged on the movable seats, and the brake pieces are arranged on the steel structure support. And the brake piece is used for limiting the position of the movable seat on the track. According to the movable foundation pit support and the underground structure construction method, the steel structure support can be moved to any position needing to be supported along the track through cooperation of the movable base and the track, and compared with the prior art, embedded parts do not need to be arranged, so that the support construction time and the foundation pit rescue time are greatly shortened, and convenience is brought to foundation pit construction.

本发明涉及一种可移动基坑支撑及地下结构施工方法，包括：轨道、移动座和钢结构支撑，所述轨道设置于基坑的围护桩上，所述钢结构支撑的两端设有所述移动座，所述移动座可移动地设置于所述轨道上，且所述移动座上设有刹车件，所述刹车件用于限制所述移动座在所述轨道上的位置。本发明提供的可移动基坑支撑及地下结构施工方法，通过移动座及轨道的配合，可将钢结构支撑沿轨道移动到任意需要支撑的位置，相比于现有技术，无需设置预埋件，从而大大减少了支撑施工时间及基坑抢险时间，对基坑施工带来了便利。
