Post-grouting device and post-grouting method for PHC tubular pile
The invention relates to the technical field of post-grouting devices, discloses a post-grouting device and a post-grouting method for a PHC (prestressed high-strength concrete) tubular pile, and solves the problem that the bearing capacity of the PHC tubular pile cannot be guaranteed due to the fact that grout flows back into a grouting device after grouting is stopped at present. A bottom plate is fixedly installed at the bottom of the grouting cylinder, stiffening ribs are fixedly connected to the outer side of the grouting cylinder at equal angles, and all the stiffening ribs are located between the bottom plate and the top plate. According to the grouting device, through cooperation of a plugging plate and a connecting shaft, when grout flows into a grouting hole, the plugging plate is extruded, then the plugging plate can rotate, the grout flows out from the position between the plugging plate and the inner cylinder, a sliding block can slide along a sliding rod through a driving rod, and a first spring is in a compressed state; and the spring I resets to drive the plugging plate to rotate reversely, so that the interior of the inner cylinder is plugged, and the grout is prevented from flowing back into the grouting cylinder.
本发明涉及后注浆装置技术领域，且公开了一种后注浆装置及PHC管桩后注浆方法，解决了目前在停止注浆后浆液会倒流回注浆器内而无法保证PHC管桩的承载力的问题，其包括注浆筒，所述注浆筒的顶部固定安装有顶板，注浆筒的底部固定安装有底板，注浆筒的外侧等角度固定连接有加劲肋，各个加劲肋均位于底板与顶板之间；本发明，通过封堵板和连接轴的配合，当浆液流入注浆孔内时对封堵板进行挤压，继而能够使得封堵板旋转，使得浆液从封堵板与内筒之间流出，并通过驱动杆能够使得滑块沿着滑杆滑动，使得弹簧一处于压缩状态，而当停止注浆时，弹簧一复位带动封堵板反向旋转，继而将内筒的内部进行封堵，从而避免浆液回流至注浆筒内。
