Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a mud circulation device for pile foundation construction. Background Art

[0002] The bored pile construction is carried out by circulating mud to protect the wall and remove the drilling cuttings. Traditional bored pile construction generally uses a mud pool for mud circulation. The mud with cuttings extracted from the pile hole is discharged into the mud pool and left to stand for the drilling cuttings to settle. A mud pump is used to pump the settled mud back into the pile hole for recycling.

[0003] After searching, the application with patent publication number CN219100056U discloses a mud filtering circulation device for pile foundation construction, including a filter frame and a filter assembly, wherein the filter assembly is fixedly mounted above the filter frame. The filter assembly is specifically composed of a transmission motor, a bearing, a turntable, a cross bar, a transmission rod, a grinding plate, a slide rail, a slider and a pulley. In this way, the grinding plate can be driven by the cross bar and the bearing to slide left and right in the filter frame for grinding, thereby preventing the filter residue from clogging the filter plate.

[0004] However, due to the setting of the filter frame and the grinding plate, the extracted mud is filtered through the filter frame, and the filtered residue remains in the filter frame after grinding, which requires stopping the circulation of the mud to remove the residue in the filter frame, affecting the construction efficiency. At the same time, during the construction of cast-in-place piles, the mud concentration is easily low after long-term filtration, affecting the formation of the pile hole, so that the concentration of the mud needs to be tested at regular intervals, and when the concentration is low, soil needs to be added to the mud.

[0005] Therefore, we proposed a mud circulation device for pile foundation construction. Utility Model Content
