Underwater concrete pouring method for cast-in-place pile
The invention provides an underwater concrete pouring method for a cast-in-place pile. The method comprises the steps that primary slag removal is conducted on a cast-in-place pile hole; after primaryslag removal is completed, a guide pipe is installed in the cast-in-place pile hole; a hopper is installed at the tail end of the guide pipe; secondary slag removal is conducted on the cast-in-placepile hole; after secondary slag removal is completed, a water-resisting plug is installed at the joint of the guide pipe and the hopper; a tank truck full of concrete is arranged beside the hopper; the concrete in the tank truck is poured into the hopper; and the water-resisting plug is opened. The underwater concrete pouring method for the cast-in-place pile has the beneficial effects that 1) thequality accident of pile breaking or slag inclusion can be avoided; 2) manufacturing of a large hopper can be avoided, and materials and labor are saved; and 3) the requirements can be met by using aconventional hopper, and the conventional hopper can be repeatedly used in quantity.
一种灌注桩水下混凝土灌注方法，所述方法包括步骤：对灌注桩孔进行一次清渣；待一次清渣完毕后在所述灌注桩孔中安装导管；在所述导管末端安装料斗；对所述灌注桩孔进行二次清渣；待二次清渣完毕后在所述导管和所述料斗连接处安装隔水塞；在所述料斗旁配置满载混凝土的罐车；将所述罐车中的混凝土倾倒入所述料斗中；开启所述隔水塞。本申请提供的一种灌注桩水下混凝土灌注方法的有益效果为：1)可避免断桩或夹渣的质量事故；2)可避免制作大料斗，节省材料、人工；3)使用常规料斗即可满足要求，可大量重复使用常规料斗。
