Supporting device for building deep foundation pit construction

LIU SAIFENG / JU WENBING / XU YONGXIANG

The invention discloses a supporting device for building deep foundation pit construction, the structure of the supporting device comprises a base plate, a supporting plate, a recycling head and an attaching piece, the attaching piece is used for attaching the inner wall of a foundation pit, the base plate and the supporting plate are unfolded, then the supporting effect is achieved, during recycling, the base plate and the supporting plate can be folded, and the recycling head is used for recycling. The whole device is flattened by folding the recycling head again, at the moment, rotating recycling can be achieved by twisting the rotating block, in the rotating process of the rotating block, the center column of the rotating column is driven to rotate due to rotation of the base block, the rolling head of the rotating column is made to rotate along the rotating ring, and after the rotating block rotates to a certain degree, the rotating ring rotates. The roller head can be pushed outwards through elastic force generated by the outer elastic piece, the roller head drives the rotating ring, the rotating ring protrudes outwards, at the moment, if falling soil adheres to a cement mixture at the rotating position, the rotating ring protrudes outwards to damage the rotating position and remove the rotating position, rotation is smooth, and the phenomenon that the rotating position is stuck and cannot be recycled is avoided.

本发明公开了一种建筑深基坑施工用支撑装置，其结构包括底盘、支撑盘、回收头、贴合片，本发明通过贴合片来贴合基坑内壁，并张开底盘和支撑盘，进而来获得支撑效果，回收时，可以将底盘和支撑盘折叠，并通过回收头再次折叠来使整个装置扁平化，此时即可通过扭动旋转块来转动回收，在旋转块转动的过程中，转动柱的中心柱会由于基块转动而被带着转动，并使其滚头沿着转动环转动，当转动到一定程度后，即可通过外弹片产生的弹力来将滚头向外推出，使其驱动转动环，使转动环向外突出，此时若转动位置有掉落的泥土与水泥混合物粘附，则可以通过转动环向外突出来对其进行破坏并将其清除，使转动柔顺，避免产生卡死而无法回收的现象。
