Water stop structure for through-wall construction of horizontal steel pipe support in foundation pit and construction method of water stop structure
The invention provides a horizontal steel pipe support through-wall construction water stop structure in a foundation pit and a construction method of the horizontal steel pipe support through-wall construction water stop structure. The horizontal steel pipe support through-wall construction water stop structure in the foundation pit comprises a concrete ring beam, an end socket steel plate, a circular steel pipe, an annular water stop steel plate, micro-expansion concrete and a circular plugging steel plate. Through-wall construction is carried out by eliminating H-shaped steel as an adapter, construction is carried out by directly penetrating a basement outer wall through a circular steel pipe, and a water stop structure of the basement outer wall is formed by matching with an annular water stop steel plate, micro-expansion concrete and a circular plugging steel plate, so that the problem of water seepage when the circular steel pipe directly penetrates through the basement outer wall is solved; meanwhile, due to the fact that the round steel pipe is high in strength and good in stability, the requirement for the stability of the supporting pressing rod under the working conditions of large span and large axial force can be met, and the supporting pressing rod can be suitable for foundation pit engineering with large fat groove width and large supporting axial force of a steel support.
本发明提供了一种基坑内水平钢管支撑穿墙施工止水结构及其施工方法，基坑内水平钢管支撑穿墙施工止水结构包括：混凝土圈梁、封头钢板、圆钢管、环形止水钢板、微膨胀混凝土及圆形封堵钢板；通过取消H型钢作为转接头进行穿墙施工，采用圆钢管直接穿地下室外墙进行施工，配合环形止水钢板、微膨胀混凝土和圆形封堵钢板形成地下室外墙的止水结构，以解决圆钢管直接穿过地下室外墙时渗水问题；与此同时，由于圆钢管强度高，稳定性好，能满足在大跨度、大轴力工况下的支撑压杆稳定性要求，可适用于肥槽宽度较宽，钢支撑支撑轴力较大的基坑工程。
