Abstract

The invention discloses a gas lift reverse circulation hole cleaning test simulation device. The gas lift reverse circulation hole cleaning test simulation device comprises: a mud mixing box; a slurry replenishing pipe, one end of the slurry replenishing pipe is connected to the mud mixing box; Waste slag collection box and conduit, one end of the conduit extends into the mud mixing box, and the other end communicates with the waste slag collection box; wherein, the conduit includes: a lift pipe and a slurry discharge pipe, and the lift pipe is arranged at In the mud mixing box, one end of the slurry discharge pipe is connected to the lifting pipe, and the other end is connected to the bottom of the waste residue collection box. The gas lift reverse circulation hole cleaning test simulation device can simulate the slag cleaning process of an actual project.

Description

technical field [0001] The invention relates to the field of underground diaphragm wall construction, in particular to a gas-lift reverse circulation hole cleaning test simulation device. Background technique [0002] During the construction of the underground diaphragm wall, as the width of the wall increases and the depth deepens, the exposure time of the groove wall increases, and the thickness of the sediment increases, which will easily cause seepage and water leakage in the foundation pit. Usually, the second cleaning is to clean the sediment through the positive circulation of mud, but when the underground diaphragm wall structure passes through the sandy silt and silty strata with high sand content, the positive circulation of the mud to clean the sediment will easily cause mud segregation. The slag cleaning time will easily cause the tank wall to collapse and affect the construction quality of the underground diaphragm wall. [0003] Air-lift reverse circulation is...
