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...

AI Technical Summary

Problems solved by technology

In this method, the position of the pile core is easy to deviate, or the mud or soil cover is close to the marked point during the drilling operation, which brings a lot of inconvenience to the construction:

[0003] The scope of sprinkling lime is large, and the deviation of the marking position is large, which may easily cause the deviation of the pile position to exceed the specification range

[0004] When objects such as steel bars are inserted, when the surrounding soil is squeezed, it is easy to cause the steel bars to shift, and it will cause inconvenience for people and machines to walk, and it is easy to trip pedestrians and cause injuries to people.

When the machine is positioned and ready to drill, it is necessary to pull out the steel bar, which will easily cause a large deviation of the pile position

[0005] Using wooden piles for positioning Due to the low strength of wooden piles, the construction site is easily damaged by vehicles, etc., and the use of wooden piles cannot start obvious signs on the site

The method of attaching red cloth with iron nails, although the red cloth can play an obvious role as a sign, but the iron nails are not firm, easy to shift, and the buried depth is low, easy to damage

[0006] When the distance between two piles is relatively close, the piles that are drilled first will easily cover the marked pile points after the soil or mud flows out, resulting in repeated positioning, which consumes manpower and material resources.
