Description

Technical Field

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

[0002] Pile foundation is a foundation form with high bearing capacity, wide application range and long history. Since the sediment at the bottom of the pile foundation hole is loose and has no bearing capacity, if it is too thick, it will cause the pile to settle too much and the settlement cannot meet the design or use requirements. Therefore, during the construction of bored piles, it is necessary to clean the sediment at the bottom of the hole to avoid excessive thickness of the sediment and create good conditions for pouring underwater concrete. In the previous pile foundation construction, the existing pile foundation sediment cleaning usually adopts the mud circulation method. The mud reverse circulation method has a relatively high hole cleaning efficiency. However, when encountering loose geology such as siltstone, the mud is sucked out from the catheter and then replenished from the hole mouth. The density of the newly replenished mud is relatively small, which causes negative pressure in the hole, causing the mud wall in the pile hole to fall off, resulting in pile foundation collapse and shrinkage problems; the mud positive circulation method has low hole cleaning efficiency because the sediment is repeatedly precipitated in the mud, and some sediments are difficult to be cleared out of the hole, affecting the construction period and the safety and quality of the project.

[0003] The disclosure (announcement) number is CN220101227U, which discloses a pile foundation sediment cleaning device, comprising a moving mechanism, a lifting mechanism arranged on the moving mechanism, and a slag scooping mechanism arranged on the lifting mechanism for scooping sediment in the pile foundation hole and filtering out slag slurry, wherein the lifting mechanism drives the slag scooping mechanism to rise or fall; the pile foundation sediment cleaning device, by realizing deep cleaning of the sediment at the bottom of the hole, is convenient and fast, and solves the existing pile foundation sediment cleaning mud circulation method. The mud reverse circulation method has a relatively high hole cleaning efficiency, but when encountering loose geological conditions such as siltstone, since the mud is sucked out from the catheter and then replenished from the hole mouth, the density of the newly replenished mud is relatively small, so that negative pressure is generated in the hole, causing the mud wall protection in the pile hole to fall off, resulting in the pile foundation collapse and shrinkage problems, and the hole cleaning efficiency is low in the mud positive circulation method because the sediment is repeatedly precipitated in the mud, and some sediments are difficult to be cleared out of the hole, affecting the construction period and the safety and quality of the project.

[0004] Although the above scheme can effectively separate and remove the sediment mixed in the mud in the pile foundation hole, the slag collecting bucket controls the discharge and stacking of materials by manipulating the placement angle of the hinge at the bottom. The closing part of the equipment on the discharge container is prone to jamming, affecting the discharge and discharge effect. The overall braking of the equipment requires operating multiple rollers one by one, which is cumbersome. For this reason, we propose a cleaning device for pile foundation holes.
