Deep foundation pit supporting structure and construction method thereof
The invention relates to the field of deep foundation pit supporting technologies, and provides a deep foundation pit supporting structure which comprises a supporting plate and an inserting pipe, the inserting pipe is connected to the supporting plate, and an avoiding hole is formed in the pipe wall of the inserting pipe in a penetrating mode; the inserting pipe is connected with a reinforcing assembly, the reinforcing assembly comprises a connecting sleeve, a telescopic sleeve and a soil breaking part, the connecting sleeve is connected to the inner wall of the inserting pipe, and an inner cavity of the connecting sleeve communicates with the receding hole; the telescopic sleeve is slidably connected to the connecting sleeve and located in an inner cavity of the connecting sleeve, and the soil breaking part is slidably connected to the telescopic sleeve and located in the telescopic sleeve; the telescopic sleeve is connected with a sealing bag made of flexible materials, the sealing bag extends in the length direction of the inserting pipe, the end of the sealing bag extends out of the inserting pipe, and the effect of improving the connecting strength between the supporting plate and the foundation pit wall at the soft foundation is achieved. The invention further provides a construction method of the deep foundation pit supporting structure. The construction method comprises the steps that the pipe inserting cavity is formed; inserting the insertion pipe into the insertion pipe cavity; and high-pressure gas is introduced into the sealing bag.
本申请涉及深基坑支护技术的领域，提供一种深基坑支护结构，其包括支护板和插接管，插接管连接于支护板，插接管的管壁贯穿开设有避让孔；插接管连接有加固组件，加固组件包括连接套筒、伸缩套筒和破土件，连接套筒连接于插接管的内壁，连接套筒的内腔与避让孔连通；伸缩套筒滑移连接于连接套筒且位于连接套筒的内腔中，破土件滑移连接于伸缩套筒且位于伸缩套筒内；伸缩套筒连接有采用柔性材料制成的密封袋，密封袋沿插接管的长度方向延伸设置且端部延伸出插接管，具有提高支护板与软基地质处的基坑壁之间的连接强度的效果。还提供一种深基坑支护结构的施工方法，包括开设插管腔；将插接管插入到插管腔中；向密封袋中通入高压气体等步骤。
