Description

Technical Field

[0002] Water-based cast-in-place piles are an engineering technology used for infrastructure construction in aquatic environments. They are mainly used for the foundation construction of water structures such as bridges, docks, and breakwaters. During the construction process, a mud circulation device is required to clean the mud, sand and gravel in the pile holes.

[0003] The existing Chinese patent with the announcement number CN114875897B discloses a reverse circulation bored pile construction device with a wall protection structure, which includes a wall protection tube and a slurry guide pipe, wherein the wall protection tube is located at the hole mouth of the pile hole, the outer wall of the wall protection tube contacts the hole wall of the pile hole, one end of the slurry guide pipe is connected to the wall protection tube, and the other end is connected to the sedimentation tank. The present application guides the slurry in the sedimentation tank through the wall protection tube and the slurry guide pipe, so that the slurry almost does not contact or impact the soil layer structure at the hole mouth of the pile hole during the process of entering the pile hole, which has the effect of improving the stability of the soil layer structure here and reducing the risk of collapse of the hole wall of the pile hole.

[0004] With regard to the above-mentioned related technologies, it is found that during the existing bored pile mud circulation process, it is necessary to dig sedimentation tanks and mud tanks at the construction site, and it is also necessary to dig mud tanks according to the drilling positions during use. This will not only occupy a large amount of construction land, but also greatly limit the flexibility of construction operations. In addition, measurement and excavation operations are required in the early stage, and the road surface needs to be repaved and repaired after the construction is completed. This increases the construction cost and reduces the construction efficiency. At the same time, the method of using sedimentation tanks to precipitate mud, sand and gravel takes a long time to operate, which is not conducive to the rapid use of mud circulation.
