Pile bottom post-grouting construction device and method
The invention relates to the technical field of grouting, in particular to a pile bottom post-grouting construction device and a method thereof.The pile bottom post-grouting construction device comprises a grouting pipe which is connected with a reinforcement cage and used for pier pile hole grouting, a plurality of grout outlet holes are formed in the lower end of the grouting pipe, and a bottom cover is welded to the lower end of the grouting pipe; a pressurizing mechanism for applying pressure to the cement paste is arranged in the mud jacking pipe in a sliding manner; in the process that the pressure applying mechanism injects water to apply pressure to cement grout in the grouting pipe to discharge the grout, the driving mechanism is driven to work and is linked with the foam breaking mechanism, a hard iron needle of the foam breaking mechanism is driven to do reciprocating up-and-down motion and axial rotation at the same time, and foam breaking work is carried out on the cement grout entering a gap of a round gravel layer. And when the grouting pipe is blocked and pressurized, the pressure is relieved through the pressure relief mechanism, the pressurization mechanism can be stopped in time, the driving mechanism and the foam breaking mechanism are made to stop working, and grouting is stopped in time.
本发明涉及压浆技术领域，具体的说是一种桩底后压浆施工装置及其方法，包括与钢筋笼连接且用于桥墩桩孔压浆的压浆管，所述压浆管下端设有若干个出浆孔，所述压浆管下端焊接有底盖，所述压浆管内部滑动设置有用于对水泥浆施压的加压机构；在施压机构注水对压浆管内的水泥浆液进行施压出浆过程中，带动驱动机构工作，与破泡机构联动，带动破泡机构的硬铁针同时做往复的上下运动以及轴向转动，对要进入圆砾层的空隙里的水泥浆液进行破泡工作，避免影响水泥浆液凝固后的强度，并且当压浆管堵塞增压时，通过泄压机构进行泄压，可以及时停止加压机构工作，使驱动机构以及破泡机构停止工作，及时停止压浆。
