Half-cover excavation cover plate supporting structure and stability early warning method
The invention relates to a half-cover excavation cover plate supporting structure which comprises a half-range cover plate, a foundation pit concrete support, a middle stand column, a linkage beam, a limiting block, a stand column jacking, a fixing bolt, a connecting rod, an external steel plate, a buffer spring, a vertical connecting rod, a cushion block and a telescopic steel wedge. The external steel plate is connected with the foundation pit concrete support, so that the supporting strength of the horizontal support is guaranteed; buffer spring supporting devices are installed on the lower sides of the limiting blocks and the stand column jacking supports, it is guaranteed that the whole structure can vertically move within a certain safety range, and the influence of vertical displacement of the middle stand column on the foundation pit concrete supporting structure is reduced. The telescopic steel wedges are arranged at the top ends of the external steel plates and the stand columns, so that the supporting effect of the middle stand columns on the cover plate structure is ensured when the middle stand columns settle and vertically displace too much; through the cushion blocks mounted at the joints of the limiting blocks and the external steel plates, the whole structure can smoothly generate vertical displacement; the construction efficiency is improved through a comprehensive three-dimensional evaluation method.
本发明涉及一种半盖挖盖板支撑结构，包括半幅盖板、基坑砼支撑、中立柱、联系梁、限位块、立柱顶托、固定螺栓、连接杆、外接钢板、缓冲弹簧、竖向连接杆、垫块和可伸缩钢楔，更涉及一种基坑稳定性评测方法；本发明通过外接钢板与基坑砼支撑相连，保证水平支撑的支撑力度；在限位块以及立柱顶托的下侧安装有缓冲弹簧支撑装置，保证整体结构能够在一定的安全范围内发生竖向位移，减小基坑砼支撑结构受到中立柱竖向位移的影响；在外接钢板和立柱顶端设置的可伸缩钢楔，保证当中立柱发生沉降竖向位移过大时，中立柱对盖板结构的支撑作用；通过限位块和外接钢板的连接处安装的垫块，整体结构能顺利发生竖向位移；通过全面立体评价方法提高施工效率。
