Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular, to a positioning device for building piling. Background Art

[0002] Pile driving refers to driving piles into the ground to make the foundation of the building solid. How deep the piles should be driven depends on the distribution of the underground strata (professionally called geological structure layers). If it can withstand the pressure of the building, the piles can be driven here. If not, they have to be deepened. In the process of construction, since the building is built on the ground, the ground needs to withstand greater pressure, so the compressive strength of the ground needs to be increased. In the process of increasing the compressive strength of the ground, piles need to be driven into the ground to increase the compressive strength of the ground. In the prior art, in the process of building piling, the pile rod is prone to offset when the pile hammer strikes the top of the pile. If the pile rod enters the ground in an offset state, it will not only fail to play a solid role, but also easily cause damage to the pile hammer. Therefore, the inventor proposes a positioning device for building piling. Utility Model Content
