Background

Pile foundation engineering has now been widely applied to construction technical field in the construction, and pile point location beats in the first step of pile foundation engineering construction, and pile core position deviation whether will directly influence the construction quality of pile foundation engineering. In the traditional method for positioning the pile point, after a total station or other instruments, steel rulers and the like are matched to find the position of the pile core, lime is directly scattered on the position, or objects such as reinforcing steel bars, wooden piles, iron nails with red cloth and the like are inserted into the position, so that the position of the pile core is marked. The method has the defects that the position of a pile core is easy to deviate, or slurry or soil coverage is close to a marked point position during drilling operation, so that a lot of inconvenience is brought to construction:

the lime spreading range is large, the marking position deviation is large, and the pile position deviation is easy to exceed the standard range.

Objects such as reinforcing steel bars are inserted, the reinforcing steel bars are easy to deflect when surrounding soil is extruded, and people and machinery are inconvenient to walk and easy to trip pedestrians, so that the people are injured. When the machine is positioned to prepare for drilling, the steel bar needs to be pulled out, and the pile position deviation is easy to cause.

The timber pile is adopted for positioning, because the strength of the timber pile is low, a construction site is easily damaged by vehicles and the like, and an obvious mark cannot be started on the site by adopting the timber pile. The method of attaching red cloth to the iron nails is adopted, and although the red cloth can play an obvious marking role, the iron nails are not firm and are easy to deviate, and the iron nails are low in buried depth and easy to damage.

When the adjacent distance of the two piles is close, the piles formed by holes are firstly formed, soil or slurry flows out and then easily covers the marked pile points around, so that repeated positioning is caused, and manpower and material resources are consumed.

Preferably, a handle is arranged at the upper part of the drill shank.

Preferably, the length of the barrel body is 20cm to 50 cm.

Through the technical scheme, lime can be poured into the soil by 20cm to 50cm instead of being only scattered on the surface of the soil, the covering soil can be removed in a covering mode of the positioning points close to the marks in the surrounding operation, and the marking points can be exposed by removing a little more soil. The hole is small, the ash is filled less, the positioning is accurate, and the deviation is not easy to occur. The original positioning points are easy to find, and the direct pile driver is time-saving, labor-saving, convenient and quick to drill in place or to check the point.
