Problems solved by technology

In order to be conveniently buried in the ground, the existing ground piles generally have a conical lower part with continuous spiral pieces on the top. However, due to the large number of spiral pieces, the casting or welding labor is increased, and the manufacturing cost is increased. Therefore, it is necessary to A new type of simple ground pile that can meet the requirements of simple construction and effectively save labor

Embodiment 1

[0017] Such as figure 1 A spiral ground pile shown includes a tubular pile body 3. The bottom of the tubular pile body 3 is formed into a pointed cone 6 by upsetting or spinning. The upper part of the tubular pile body 3 is provided with four through holes, wherein There are 3 through holes distributed, the nuts 1 are welded on the outside of these three through holes, the remaining one through hole 2 is exhausted, and the middle and lower parts of the tubular pile body 3 are respectively welded with a section of helical blade 4,5. The helical blade 5 at the bottom of the tubular pile body 3 is connected to the pointed cone 6 . Such as Figure 4 As shown, the pointed cone portion 6 is a quadrangular pyramid with four cutting ridges from top to bottom. Such as figure 2 , image 3 As shown, the helical blades 4 and 5 in the middle and lower parts of the tubular pile body 3 are both in the shape of open coils. A through hole 7 is opened on the tapered portion 6 of the tubul...

Abstract

The invention discloses a spiral ground pile which comprises a tubular-shaped pile body, wherein the bottom of the tubular-shaped pile body is provided with a sharp cone part, the sharp cone part is provided with two to eight cutting ridges from top to bottom, the upper part of the tubular-shaped pile body is provided with multiple through holes, the outside of at least one through hole is welded with a nut, and a spiral blade is arranged on the tubular-shaped pile body. The technical scheme disclosed by the invention can not only facilitate the construction and meet the strength requirement of anchoring, but also effectively reduce the cost and save the labor capacity.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a spiral ground pile. Background technique [0002] The application of ground piles in engineering construction is very large, and it is widely used in many fields such as house construction, railway engineering, wind power generation and solar power generation. Ground piles are the key to the load-bearing and stability of buildings. In order to be conveniently buried in the ground, the existing ground piles generally have a conical lower part with continuous spiral pieces on the top. However, due to the large number of spiral pieces, the casting or welding labor is increased, and the manufacturing cost is increased. Therefore, it is necessary to A simple ground pile is a new type of ground pile which can not only meet the requirement of simple construction but also can effectively save labor. Contents of the invention [0003] In order to solve the above-mentioned technical probl...
