摘要
当灌注竖管混凝土发生堵管断桩或拔漏管断桩时,应采用二次埋竖管办法,按程序重新灌桩或采用泥浆二次清底并用富砂浆重新埋管3m,这两种重新灌注方法可避免造成工程断桩,保证施工质量,减少补桩损失。
In case,fracture of the cast in-situ pile occurs due to the blockage of vetical pipe in casting or due to the pipe pulling out,the method of embedding another vertical pipe should be used.And then,the pile is casted in-situ again or the bottom is cleaned with mud and a new pipe is embedded by 3 meters with fat motor.The methods can prevent pile from fracturing and ensure the quality of construction to relieve the loss of supplementary pile.
