Basement foundation pit supporting structure and construction method thereof
The invention relates to a basement foundation pit supporting structure, and belongs to the technical field of foundation pit supporting. The device comprises three-axis stirring piles which are arranged on the side wall of a foundation pit and are in lap joint with one another, pit wall grid type cement stirring piles are in lap joint with the sides, away from the foundation pit, of the three-axis stirring piles, and high-pressure jet grouting piles are arranged at the bottom ends of the three-axis stirring piles. Steel pipe piles are inserted into the three-axis stirring piles and the row, away from the foundation pit, of the pit wall grid type cement stirring piles at intervals, and cast-in-place piles are arranged in the row, in lap joint with the outer sides of the three-axis stirring piles, of the grid type cement stirring piles at intervals. Anchoring parts used for reinforcing the supporting performance of the three-axis mixing piles are arranged between the three-axis mixing piles and the side wall of the foundation pit. Due to the arrangement of the cast-in-place piles and the anchoring parts, the rigidity of the supporting structure is further enhanced, and the problem that the load at the junction of the first-layer basement and the second-layer basement is large is effectively solved.
本申请涉及一种地下室基坑支护结构，属于基坑支护的技术领域。其包括设置在基坑侧壁且相互搭接的三轴搅拌桩，所述三轴搅拌桩远离基坑的一侧搭接有坑壁栅格式水泥搅拌桩，所述三轴搅拌桩的底端设置有高压旋喷桩，所述三轴搅拌桩内和坑壁栅格式水泥搅拌桩远离基坑的一排间隔插入有钢管桩，与所述三轴搅拌桩外侧搭接的一排栅格式水泥搅拌桩内间隔设置有灌注桩，所述三轴搅拌桩与基坑侧壁之间设置有用于加固三轴搅拌桩支护性能的锚固件。本申请灌注桩和锚固件的设置进一步增强了支护结构的刚性，有效改善了一、二层地下室交界处荷载较大的问题。
