High-strength tubular pile foundation pit support structure for geotechnical engineering
The invention discloses a high-strength tubular pile foundation pit support structure for geotechnical engineering. The high-strength tubular pile foundation pit support structure comprises a pile body and a top cap. The high-strength tubular pile foundation pit support structure has the beneficial effects that an upper sliding plate, a lower sliding plate, a soil piercing rod and a steel column are adopted, the top surface of the top cap covers the top surface of a top steel ring in the foundation pit support process, the top surface of an avoidance groove is abutted with the top surface of the steel column at the moment, the top cap is pressed downwards by adopting a static pile press machine, the pile body is pushed into a soil layer by the top cap, after the pile body is driven to the set depth, the direction of the top cap is adjusted, the top surface of the avoidance groove is abutted with the top surface of the steel column, the top cap is continuously pressed downwards by adopting the static pile press machine, and the steel column is pushed to move downwards by the top cap, so that the upper sliding plate and the lower sliding plate are pushed to move downwards, then the soil piercing rod is pushed to obliquely move downwards to pierce into soil and extend into the soil like plant rooting, and the pulling resistance of the bottom of the pile body and the soil is increased, the mounting stability of the pile body is increased, the mounting strength is increased, and the device is stable and reliable.
本发明公开了一种岩土工程用高强度管桩基坑支护结构，包括桩体和顶帽。有益效果：本发明采用了上滑动板、下滑动板、刺土杆和钢柱，在进行基坑支护的过程中，将顶帽底面盖在顶钢圈顶面，此时让位槽顶面与钢柱顶面抵接，采用静压桩机向下压顶帽，顶帽推动桩体进入到土层中，打入到设定深度后，调转顶帽方向，使让位槽顶面与钢柱顶面抵接，继续使用静压桩机向下压顶帽，顶帽推动钢柱向下移动，从而推动上滑动板和下滑动板向下移动，进而推动刺土杆斜向下移动刺入到土壤中，像植物生根一样延伸至土壤中，增加了桩体底部与土壤的抗拉拔力，提高了桩体安装的稳定性，从而提高了安装强度，使本装置更加稳定可靠。
