Cast-in-situ bored pile hole cleaning device and method
The invention discloses a cast-in-situ bored pile hole cleaning device and method. The device comprises an air compressor and a slurry pump, and further comprises an air conveying pipe, a hole cleaning pipe, an air conveying ring and air spraying heads; the air compressor is connected with the air conveying pipe, and the slurry pump is connected with the hole cleaning pipe; the air conveying ring is fixedly installed at the bottom end of the hole cleaning pipe and connected with the bottom end of the air conveying pipe; and the air conveying ring is of a hollow annular structure, the multiple air spraying heads are evenly distributed and fixedly installed on the inner wall of the air conveying ring, and the air spraying heads face the inclined lower portion. According to the cast-in-situ bored pile hole cleaning device and method, air is conveyed to the air conveying ring through the air conveying pipe, and then the air is sprayed out from the air spraying heads after being distributed by the air conveying ring; due to the fact that the air spraying heads face the inclined lower portion, the air is sprayed out towards the interior of the hole cleaning pipe and the lower portion of the hole cleaning pipe, and then the air and slurry are mixed; and meanwhile, the downwards-sprayed air disturbs sediment at the bottom of a pile hole body, the sediment is promoted to enter the hole cleaning pipe, and therefore the situation that the sediment at the bottom of the pile hole is deposited, and the hole cleaning effect is influenced can be avoided.
本发明公开了一种钻孔灌注桩清孔装置及方法，所述装置包括空气压缩机和泥浆泵，还包括输气管、清孔管、输气环和喷气头，空气压缩机与输气管连接，泥浆泵与清孔管连接；所述输气环固定安装在清孔管底端，并与输气管底端连接；所述输气环为中空环状结构，多个所述喷气头均匀分布固定安装在输气环内壁上，所述喷气头朝向为斜下方。本发明通过输气管对输气环进行输气，进而气体经由输气环分配后从喷气头喷出，由于喷气头斜向下方，进而气体向清孔管内和清孔管下方喷出，进而气体与浆液混合，同时，向下喷出的气体对桩孔本体底部的沉渣进行扰动，促使沉渣进入到清孔管内，从而能够避免桩孔底部沉渣发生沉积，影响清孔效果。
