Method for cleaning drill hole
The invention discloses a method for cleaning a drill hole. The method comprises the following steps: S1, communicating a slurry inlet connector of a cyclone desander with a water outlet water head of a pile hole, and communicating a slurry outlet connector of the cyclone desander with a slurry pool; S2, feeding the slurry into the cyclone desander through the water outlet water head of the pile hole, wherein the slurry with certain pressure rotates in a mud-sand separation barrel; S3, separating out sand grains with large specific gravity through rotation and discharging the sand grains from a sand discharging opening, and feeding slurry with small specific gravity into the slurry pool from a slurry outlet; S4, pumping the slurry in the slurry pool after being fully mixed into the pile hole through a sewage pump and then feeding the slurry into the cyclone desander through the water outlet water head of the pile hole, and repeating the process; and S5, after the perfusion catheter is installed, repeating the steps S1 to S4 for secondary hole cleaning. The invention provides a method capable of efficiently and simply cleaning the drill hole.
本发明公开一种清理钻孔的方法,包括以下步骤:S1、将旋流除砂器的进浆接口与桩孔的出水口水头相连通,旋流除砂器的出浆接口与泥浆池相连通;S2、泥浆经桩孔的出水口水头进入旋流除砂器内,带有一定压力的泥浆在泥砂分离筒内形成旋转运动;S3、经旋转分离出比重大的砂粒从排砂口排出,比重小的泥浆从出浆口进入泥浆池内;S4、泥浆池内泥浆充分混合后经污水泵抽入桩孔内,再由桩孔的出水口水头进入旋流除砂器,如此反复循环;S5、安装灌注导管后重复步骤S1‑S4,进行二次清孔;本发明提供了一种能够高效、简单地清理钻孔的方法。
