Secant pile structure with reinforcing function and construction method thereof
The invention provides a secant pile structure with a reinforcing function and a construction method thereof. The secant pile structure comprises first secant piles and second secant piles, wherein the plurality of first secant piles and the plurality of second secant piles are alternately engaged and connected to form a secant pile; a crown beam is arranged at the upper part of the secant pile, reinforcement cage stirrups are annularly arranged in the first secant piles, and reinforcement cage longitudinal reinforcements are longitudinally arranged perpendicular to the reinforcement cage stirrups; and grouting pipes are further longitudinally arranged in the first secant piles and used for grouting and repairing leakage into the secant pile. The secant pile structure has the beneficial effects that the secant pile structure is simple, the stress is scientific and reasonable, the construction is convenient, the construction cost is low, the construction period is not increased, and the construction quality is safe and reliable. Through a local uniform reinforcement distribution mode, the distance between longitudinal stress ribs of a reinforcement cage is adjusted, so that the reinforcement of the secant pile is more reasonable and more conforms to the stress characteristics, and the problem of foundation pit leakage caused by insufficient occlusion width of the secant pile due to the design reason, construction process or improper operation of the secant pile is solved.
本发明提供一种具有补强功能的咬合桩结构及其施工方法，包括：第一咬合桩和第二咬合桩，多个所述第一咬合桩和多个所述第二咬合桩交替咬合连接成咬合桩；所述咬合桩上部设置有冠梁，所述第一咬合桩内部环向设置有钢筋笼箍筋，垂直所述钢筋笼箍筋纵向设置有钢筋笼纵向钢筋；所述第一咬合桩内部还纵向设置有注浆管，用于向所述咬合桩内注浆补漏。本发明的有益效果是该咬合桩结构简单、受力科学合理，施工便捷，施工成本低，不增加施工周期，施工质量安全可靠。通过局部均匀布筋方式，调整钢筋笼纵向受力筋的间距，使咬合桩配筋更加合理，更加符合受力特点，解决因咬合桩设计原因、施工工艺或操作不当，导致的咬合桩咬合宽度不足造成基坑渗漏难题。
