Connecting device for foundation pit supporting inner support and self-adjusting axial force control mechanisms
The invention discloses a connecting device for a foundation pit supporting inner support and self-adjusting axial force control mechanisms, and belongs to the technical field of foundation pit supporting. The connecting device comprises M limiting grooves formed in the foundation pit supporting and the self-adjusting axial force control mechanisms with the same number as the M limiting grooves, and each self-adjusting axial force control mechanism comprises a first air chamber embedded in the corresponding limiting groove, a second air chamber connected with the inner support, a partition block correspondingly connected with the first air chamber and the second air chamber, a first elastic assembly and a second elastic assembly; the partition blocks are slidably arranged in the limiting grooves; the first elastic assemblies are correspondingly connected with the foundation pit supporting and the separation blocks, and the first elastic assemblies are located in the first air chambers; and the second elastic assemblies are connected with the inner support and the partition blocks and located in the second air chambers. The technical effects that any form of deformation of the foundation pit supporting is converted into uniform axial deformation of the inner support, the inner support is only subjected to uniformly distributed axial force, and the safety of foundation pit excavation and support construction is improved are achieved.
本发明公开了用于基坑支护内支撑的连接装置及自调节轴力控制机构，属于基坑支护技术领域，包括形成于基坑支护上的M个限位槽、与M个限位槽数量相同的自调节轴力控制机构，每一个自调节轴力控制机构包括：第一气室嵌入限位槽内；第二气室和内支撑连接；分隔块分别与第一气室和第二气室连接，分隔块滑动的设置于限位槽内；第一弹性组件分别与所述基坑支护和所述分隔块连接，所述第一弹性组件位于所述第一气室内；第二弹性组件分别与所述内支撑和所述分隔块连接，所述第二弹性组件位于所述第二气室内。本发明达到将基坑支护任意形式的变形转化为内支撑的均匀轴向变形，使内支撑只受均匀分布的轴向力，提高基坑开挖与支护施工的安全性的技术效果。
