Connecting structure of large-section waist beam and secant pile and construction method
The invention discloses a connecting structure of a large-section waist beam and a secant pile and a construction method, the waist beam is fixed on the secant pile through the connecting structure, and the connecting structure comprises anti-falling steel bars, welding steel bars and embedded steel bars; one end of the anti-falling steel bar is welded to the pile body position, above the waist beam, of the secant pile, and the other end of the anti-falling steel bar is anchored downwards to the bottom of the waist beam from the upper end of the position, away from the secant pile, of the waist beam. The embedded steel bars are L-shaped, one ends of the embedded steel bars are anchored into the waist beams, and the other ends of the embedded steel bars are embedded into pile bodies, corresponding to the mounting positions of the secant piles and the waist beams, of the secant piles; one end of the welding steel bar is welded to a main bar of the secant pile, and the other end of the welding steel bar is anchored into the waist beam. According to the connecting structure, the problems that the waist beam is large in self weight and difficult to connect with the secant piles can be solved, a connecting system formed through the construction method can meet the stress requirement, and the safety of deep foundation pit supporting and the stability of a foundation pit are guaranteed.
本发明公开了一种大截面腰梁与咬合桩的连接结构及施工方法，腰梁通过连接结构固定在咬合桩上，连接结构包括防坠钢筋、焊接钢筋和植筋钢筋；防坠钢筋的一端焊接在咬合桩位于腰梁以上的桩体位置，防坠钢筋的另一端从腰梁远离咬合桩的位置上端向下锚至腰梁底部；植筋钢筋为L形，植筋钢筋的一端锚入腰梁，植筋钢筋的另一端植入咬合桩与腰梁安装位置对应的桩体内；焊接钢筋为匚形，焊接钢筋的一端与咬合桩的主筋焊接，焊接钢筋的另一端锚入腰梁。本发明的连接结构能够解决腰梁自身重量大、与咬合桩连接困难的问题，通过采用本发明的施工方法形成的连接体系能够满足受力要求，保证了深基坑支护的安全性与基坑稳定性。
