Hole cleaning device for building rotary excavating drilled pile
The invention relates to the technical field of pile hole cleaning, in particular to a building rotary excavating drilled pile hole cleaning device which comprises a frame, a rotating column is installed below the frame through a downward rotating mechanism, a lower disc is fixedly connected to the lower end of the rotating column, an upper disc is rotatably connected to the outer wall of the rotating column, and the lower end of the upper disc is attached to the upper end of the lower disc. A limiting mechanism is arranged between the upper disc and the lower disc, when the slurry pump pumps slurry in a pile hole, sludge adhering to the inner walls of the multiple sections of pile casings can be cleaned away by the multiple scraping plates which rotate and move downwards, and the device is suitable for the pile casings with different calibers. Sludge scraped from the inner wall of the pile casing, sediment at the bottom in slurry and suspended sludge in the slurry can be continuously pumped away, and therefore the performance of a follow-up cast-in-place pile is improved. And the scraper is not easy to damage. And the surface of the filter screen of the slurry pump can be cleaned and vibrated, so that the filter screen is not easily blocked by sludge, and the slurry pumping efficiency of the slurry pump is ensured.
本发明涉及桩孔清理技术领域，具体为一种建筑旋挖钻孔桩清孔装置，包括框架，所述框架的下方通过下旋机构安装有转柱，所述转柱的下端固定连接有下盘，所述转柱的外壁转动连接有上盘，所述上盘的下端与下盘的上端相贴合，所述上盘与下盘之间设有限位机构，泥浆泵在对桩孔内的泥浆进行抽取的同时，多节护筒内壁上粘附的泥渣会被多块旋转下移的刮板给清理掉，且适用于不同口径的护筒，可将护筒内壁刮下来的泥渣、泥浆中底部的沉渣以及泥浆中悬浮的泥渣给不断抽走，从而提高后续灌注桩的性能。刮板不易损坏。泥浆泵的滤网表面会得到清扫与受到振动，使得滤网不易被泥渣堵塞，保证泥浆泵对泥浆的抽取效率。
