Pump lift reverse circulation device for hole cleaning of cast-in-place concrete pile
The invention discloses a pump lift reverse circulation device for hole cleaning of a cast-in-place concrete pile, which comprises a slurry pump, the slurry pump is placed in a guide pipe, a sealing piece is arranged between the slurry pump and the guide pipe, an outlet of the slurry pump is provided with a guide plate for guiding slurry upwards, and a connecting chain with adjustable length is connected above the slurry pump. The upper end of the connecting chain is connected with a slurry output pipe, and the slurry output pipe is detachably connected with the top of the guide pipe in a matched mode. The device can achieve the rapid hole cleaning effect in the prior art, and is low in operation cost and easy and convenient to use.
本发明公开一种混凝土灌注桩清孔用泵举反循环装置，包括泥浆泵，所述泥浆泵放置于导管内，泥浆泵与导管之间设置有密封件，所述泥浆泵的出口设置有用于将泥浆向上引导的导流板，所述泥浆泵上方连接有长度可调的连接链，所述连接链的上端连接有泥浆输出管，所述泥浆输出管与导管的顶部可拆卸式配合连接。该装置可以实现现有技术中快速清孔的效果，且运营成本低，使用简单方便。
