Air-lift reverse circulation equipment of sediment in pile hole
The invention relates to the technical field of pile holes, and discloses air-lift reverse circulation equipment of sediment in a pile hole. The air-lift reverse circulation equipment of the sediment in the pile hole comprises a slag removal barrel, wherein a containing cavity with an opening in the top is formed in the slag removal barrel, an airflow pipe is arranged in the containing cavity, an airflow channel is formed in the airflow pipe, the top of the slag removal barrel is connected with a horizontal rod, and the two ends of the horizontal rod are connected with the top of the slag removal barrel correspondingly; a lifting ring is convexly arranged in the middle of the horizontal rod and is connected with a lifting chain; the airflow pipe is connected with an air pipe which is connected with an air compressor; during hole cleaning, high-pressure air is fed into the bottom of the pile hole to be mixed with slurry at the bottom of the pile hole to form a gas-liquid mixture, and the gas-liquid mixture ascends and flows along the interval of the side wall; due to the fact that no closed space is formed above the slag removal barrel, the gas-liquid mixture loses further kinetic energy and descends to the inner part of the slag removal barrel and the bottom of the pile hole after the gas-liquid mixture ascends to a certain height; part of the sediment is accumulated in the slag removal barrel, so that air-lift reverse circulation hole cleaning of the sediment in the pile hole is formed, the operation is simple, and the sediment at the bottom of the pile hole is convenient to clean.
本发明涉及桩孔的技术领域，公开了桩孔沉渣气举反循环设备，包括清渣桶，清渣桶中具有顶部开口的容腔，容腔中设有气流管，气流管中具有气流道，清渣桶的顶部连接有水平杆，水平杆的两端分别与清渣桶的顶部连接，水平杆的中部凸设有吊环，吊环上连接有吊链；气流管连接有气管，气管与空压机连接；清孔时，将高压空气送入桩孔底部与桩孔底部的泥浆混合，形成气液混合体，气液混合体沿侧壁间距上升流动，由于清渣桶的上方未形成封闭空间，气液混合体在上返一定高度后，则失去进一步的动能，下降至清渣桶内和桩孔的底部，部分沉渣积盛在清渣桶内，这样就形成了桩孔内沉渣气举反循环清孔，操作简单，且便于清理桩孔底部的沉渣。
