Water stopping method for steel pipe pile fore shaft
The invention discloses a water stopping method for a steel pipe pile fore shaft. The water stopping method comprises the following steps that a phosphoric acid solution and a water glass solution areinjected into the bottom of the fore shaft at the same time through a drill rod, and a grout stopping layer is formed; and cement paste and the water glass solution are injected into the area above the grout stopping layer of the fore shaft through the drill rod at the same time for plugging. According to the water stopping method for the steel pipe pile fore shaft, the diffusion speed and distance of grout in water can be effectively controlled, it is guaranteed that a water flowing channel is rapidly blocked under the condition that water flows, and therefore the water stopping effect is good, grouting can go deep into the bottom of the fore shaft through the drill rod, saturated grouting is conducted from bottom to top, and water stop effect is better.
本发明涉及一种用于钢管桩锁口的止水方法，其包括以下步骤：通过钻杆向锁口底部同时注入磷酸溶液和水玻璃溶液，形成止浆层；通过所述钻杆向所述锁口的止浆层以上区域同时注入水泥浆和水玻璃溶液进行封堵。本发明涉及的一种用于钢管桩锁口的止水方法，可有效地控制浆液在水中的扩散速度和距离，确保在有水流动的情况下，迅速堵住水的流动通道，因此，止水效果较好，并且，通过所述钻杆来注浆可以深入所述锁口底部，从下至上饱和注浆，止水效果更佳。
