Digging foundation enlarged bottom section support structure
The invention relates to a digging foundation enlarged bottom section support structure, and belongs to the field of railway station construction. The digging foundation enlarged bottom section support structure comprises a plurality of support assemblies used for supporting on the top wall of a cavity. Each support assembly comprises a plurality of main beams arranged at intervals, abutting pieces used for abutting on the top wall of the cavity are arranged on the multiple main beams of each support assembly, and each support assembly further comprises support pieces used for driving the abutting pieces to abut on the top wall of the cavity. The supporting assemblies are arranged after an operator excavates a certain width when excavating the cavity, and the supporting pieces can abut theabutting pieces on the top wall of the cavity, so that the abutting pieces have a supporting effect on the top wall of the cavity. At that time, the next section is excavated, and the supporting assemblies are arranged, collapse of the top wall of the cavity is prevented, and therefore serous safety accidents are prevented.
本申请涉及一种掏挖基础扩底段支护结构，属于铁路车站施工领域，包括多个用于支撑至腔体顶壁上的支撑组件，每个所述支撑组件均包括间隔设置的多个主梁，每个支撑组件的多个主梁上均设置有用于抵接至腔体顶壁上的抵接件，每个所述支撑组件还包括用于带动抵接件抵紧至腔体顶壁上的支撑件，操作人员在掏挖腔体时挖出一定宽度后设置支撑组件，支撑件可将抵接件抵接至腔体顶壁上，使得抵接件对腔体顶壁起到支撑的效果，此时再掏挖下一段设置支撑组件，防止腔体顶壁出现坍塌，从而防止出现严重的安全事故。
