Fabricated portal rigid frame structure supporting system and construction method thereof
The invention discloses a fabricated portal rigid frame structure supporting system and a construction method thereof. The supporting system comprises two rows of piles and an H-shaped steel coupling beam connected between the two rows of piles. Each row of piles comprises a plurality of H-shaped steel piles vertically arranged at intervals and U-shaped steel sheet piles assembled between every two adjacent H-shaped steel piles. The straight line edge of the U-shaped steel sheet pile is connected with the flange side edge of the H-shaped steel pile; the H-shaped steel piles in the two rows of piles are oppositely arranged, flanges are opposite, and the upper portions of the H-shaped steel piles are connected through H-shaped steel connecting beams to form a rectangular door type rigid frame structure. The supporting system is safe, reliable, high in overall flexural rigidity, high in deformation control capacity and capable of effectively retaining soil and stopping water, all the components are pre-machined and formed and can be quickly assembled on site, and the cyclic utilization rate of all the components is high; the method is particularly suitable for deep foundation pit engineering which is large in foundation pit excavation area and does not need to be provided with a horizontal inner support.
本发明公开了一种装配式门式刚架结构支护体系及其施工方法。支护体系包括两排桩和连接在两排桩间的H型钢连梁；每排桩中，包括：竖向间隔设置的多根H型钢桩、和拼装在相邻两H型钢桩之间的U型钢板桩；所述U型钢板桩的直线边与H型钢桩的翼缘侧边连接；两排桩中的H型钢桩相对设置，且翼缘相对并且上部通过H型钢连梁连接，形成矩形门式刚架结构。本发明支护体系安全可靠，整体抗弯刚度大，变形控制能力强，可有效挡土和止水，各部件预加工成型，可现场快速拼装，各部件循环利用率高；本发明特别适用于基坑开挖面积大，且无须设置水平内支撑的深基坑工程。
