Foundation pit engineering concrete support changing force transmission belt capable of pre-applying axial force
The invention discloses a foundation pit engineering concrete support changing force transmission belt capable of pre-applying axial force, and aims to provide the foundation pit engineering concrete support changing force transmission belt capable of pre-applying the axial force, which can provide temporary compensation support in a foundation pit support dismounting stage so as to effectively solve the problem of excessive deformation of a foundation pit enclosure wall caused by support dismounting and support changing. The device comprises a floor slab force transmission belt, the floor slab force transmission belt is arranged between a foundation pit enclosure wall and a corresponding basement floor plate, and the floor slab force transmission belt and the corresponding basement floor plate are connected into a whole; the floor slab axial force pre-applying device comprises a floor slab force transferring bracket fixed to the corresponding basement floor slab and a hydraulic jack located between the floor slab force transferring bracket and the foundation pit enclosure wall. And after the hydraulic jack applies axial force between the floor plate force transmission bracket and the foundation pit enclosure wall, a gap generated between the floor plate force transmission belt and the foundation pit enclosure wall is filled with a high-strength grouting material.
本发明公开了一种可预加轴力的基坑工程混凝土换撑传力带，旨在提供一种能够在基坑拆撑阶段提供临时性的补偿支撑，从而有效的减小因拆撑、换撑导致基坑围护墙产生过大变形的问题的可预加轴力的基坑工程混凝土换撑传力带。它包括楼板传力带，楼板传力带布置在基坑围护墙与对应的地下室楼层板之间，楼板传力带与对应的地下室楼层板连为一体；楼板预加轴力装置，楼板预加轴力装置包括固定在对应的地下室楼层板上的楼层板传力牛腿及位于楼层板传力牛腿与基坑围护墙之间的液压千斤顶。当液压千斤顶在楼层板传力牛腿与基坑围护墙之间施加轴力后，楼板传力带与基坑围护墙之间产生的间隙采用高强灌浆料填充。
