Device for precision positioning of pedal steel chisel pore-forming pile point, manufacturing method and using method

Abstract

The invention provides a device for precision positioning of a pedal steel chisel pore-forming pile point, a manufacturing method and a using method. The device comprises a steel chisel, an ash filling barrel and a hopper, the steel chisel comprises a chisel body, a chisel head, a pedal and a level gauge, the chisel head is located at the lower end of the chisel body and in a cone shape, the pedal is located below the chisel body, and the level gauge is located at the top of the chisel body; the ash filling barrel comprises a hollow barrel body and an ash filling barrel handle located on the upper part of the barrel body, the barrel body sleeves the chisel body, the inner wall of the barrel body is attached to the outer wall of the chisel body, and the length of the barrel body is smaller than the distance from the chisel head to the pedal; the outer diameter of the lower end of the hopper is smaller than the inner diameter of the barrel body, lime can be grouted into soil in 20 cm-50 cm, instead of only scattering on the surface of the soil, when operation is conducted around and the positioning point close to a mark is covered, the covering soil can be wiped out, the marking point position can be exposed by wiping a little more soil, the hole is small, ash filling is less, positioning is accurate, deviation is not prone to occurring, the original positioning point is easy to find, time and labor are saved, and convenience and fastness are achieved.

Description

technical field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a device for precise positioning of pile points formed by stepping on steel and drilling holes. Background technique

[0002] Pile foundation engineering in building construction is now widely used in the field of construction technology. Pile point positioning is the first step in the construction of pile foundation engineering. Whether the position of the pile center deviates will directly affect the construction quality of pile foundation engineering. The traditional pile point positioning method is to use a total station or other instruments, steel rulers, etc. to find out the pile core position, and then directly sprinkle white ash on this position, or insert steel bars, wooden piles, iron nails and red cloth, etc. Objects to mark the position of the pile center. In this method, the position of the pile core is easy to deviate, or the mud or soil c...
