The invention provides gas lift reverse circulation hole cleaning equipment and a hole cleaning method for diaphragm wall construction, and belongs to the field of buildings. The gas lift reverse circulation hole cleaning equipment comprises a slurry feeding guide pipe, a tank cleaning guide pipe, an air feeding assembly and a sediment separator, the slurry feeding guide pipe is connected into anexcavation groove and used for providing slurry for the excavation groove; the groove cleaning guide pipe is vertically arranged, is provided with an opening in the bottom and is mounted at an openingof the excavation groove, the bottom end is close to the bottom of the excavation groove, and the top end is connected to the sediment separator; and the bottom of the air feeding assembly communicates with the interior of the lower portion of the groove cleaning guide pipe, forms an included angle with the groove cleaning guide pipe and is used for conveying compressed air into the interior of the lower portion of the groove cleaning guide pipe. The gas lift reverse circulation hole cleaning equipment is simple in construction, high in hole cleaning speed and thorough in groove cleaning anddeslagging, and slurry can be recycled.
Description
technical field [0001] The present application relates to the construction field, in particular to a gas-lift reverse circulation hole cleaning device and a hole cleaning method for ground connection wall construction. Background technique [0002] The key point of the construction of the ground connection wall is the trench construction, so the development of the trench formation technology determines the development of the construction technology of the underground diaphragm wall. Now the ground connection wall construction technology is mature, and there are many construction equipment for the ground connection wall, such as impact drilling rigs, slotting machines, rotary drilling rigs, and double-wheel slotting machines. At present, the ground-to-wall equipment used at home and abroad mainly includes hydraulic grabs, and high-end double-wheel milling machines. The equipment has a wide range of use and high work efficiency, which fully represents the most cutting-edge co...
