Foundation pit prestress enclosure supporting structure and construction method of foundation pit
The invention provides a foundation pit prestress enclosure supporting structure and a construction method of a foundation pit. The foundation pit prestress enclosure supporting structure comprises enclosure piles and a connecting beam and further comprises a plurality of stress rows, the stress rows are distributed on the inner side of the connecting beam at intervals in the length direction of the connecting beam, and each stress row comprises a supporting beam and a plurality of supporting stress piles; and one end of each supporting beam is perpendicular to the connecting beam, the other end of each supporting beam is arranged towards the interior of the foundation pit in an overhanging mode, all the supporting stress piles of each stress row are used for supporting the corresponding supporting beam, and all the supporting stress piles apply acting force towards the interior of the foundation pit. By the adoption of the stress rows, under the condition that the deformation amount of the enclosure piles on the outer edge of the foundation pit is the same as that in the prior art, the number of the supporting stress piles and the number of the supporting beams are small, the length of the supporting beams is small, the material cost can be reduced, the construction task load can be reduced, and the construction difficulty is lower.
本发明提供一种基坑预应力围护支撑结构及基坑的施工方法。一种基坑预应力围护支撑结构，包括围护桩和连接梁，还包括若干受力排，所有所述受力排沿所述连接梁的长度方向间隔分布于所述连接梁的内侧，所述受力排包括支撑梁和若干支撑受力桩，所述支撑梁一端垂直于所述连接梁、另一端悬挑朝向基坑内部设置，每个所述受力排的所有所述支撑受力桩用于支撑所述支撑梁，所有所述支撑受力桩均施加有朝向所述基坑内部的作用力。采用所述受力排，能够使得基坑外缘的围护桩的变形量在与现有技术中相同的情况下，支撑受力桩、支撑梁的设置数量均较少，且支撑梁的长度较短，能够减少材料成本、施工任务量，施工难度更低。
