Description

Technical Field

[0001] The present invention relates to the technical field of rotary pile drilling, and in particular to a pile position verification device for assisting rotary pile drilling. Background Art

[0002] Generally refers to a type of pile constructed using a rotary drilling rig. Its full name is rotary bored cast-in-place pile, or simply rotary bored pile in engineering. Because it uses machinery, it requires fewer workers, significantly saving labor costs. A rotary drilling rig first uses a barrel-shaped drill bit with a valve at the bottom to crush rock and soil, directly loading it into the drill bucket. The drill bucket is then lifted out of the hole using the rig's hoist and telescopic drill rod to unload soil. This cycle repeats, continuously removing and unloading soil until the designed depth is reached. For well-cohesive rock and soil, dry or water drilling techniques can be used, eliminating the need for slurry wall support. However, for loose, easily collapsing strata, or those with groundwater, where the borehole wall is unstable, static slurry wall drilling is required, injecting a retaining slurry or stabilizing fluid into the hole to protect the wall. Currently, during the construction of a rotary bored pile, surveying and setting out are performed on a roughly leveled site. Construction baselines and auxiliary baselines are used to determine the bored pile positions, which are then clearly marked with bamboo stakes or other similar markings. When verifying the pile position of rotary bored piles, two pieces of wood or steel pipes are generally placed on the steel casing, and the cross positioning method is adopted to roughly select the center of the pile for verification.

[0003] The existing auxiliary pile position verification equipment for rotary bored piles does not have the function of rapid positioning. Generally, when verifying the pile position of rotary bored piles, the device is placed inside the casing and then the telescopic rod is adjusted so that the support plate of the telescopic rod is supported by the inner wall of the casing. Adjustment needs to be made multiple times, which is very troublesome, increases the workload, reduces the efficiency of positioning, and is not convenient for adjusting the level. Generally, after installation, the level of the auxiliary verification device is difficult to grasp. If the installation is tilted, the measurement accuracy of the center point is affected. It is necessary to ensure the level of the device. Generally, after installation, a spirit level is placed on the surface of the device to measure the level of the device. If it is not level, the device needs to be disassembled, adjusted and then installed, and then measured and installed again until the adjustment is completed. The entire adjustment process is cumbersome, the workload is large, the efficiency is low, and it is inconvenient to use. Summary of the Invention
