Abstract

The invention relates to a tool in the field of construction and particularly relates to a spiral ground pile applied to gobi topography with more roundstone, geology with hard soil quality and other geologies. The spiral ground pile comprises a pile body, wherein one end of the pile body is provided with an externally-connected end, and the other end of the pile body is a rotary bit end; the external peripheral surface of the pile body is provided with a helical blade; the rotary bit end comprises a bit body positioned at the center of the end part; and the outer side of the bit body is provided with multiple oblique pull sheets which deflex towards a same direction. The invention further provides a spiral ground pile which can be used for effectively loosening large particulate matters such as breccia and roundstone, has better propulsive force and loosening force, can be conveniently inserted into the gobi topography with more roundstone, and is small in energy consumption; and the spiral ground pile can be used for solving the technical problems that the ground pile in the prior art is only applicable to common soil quality, is high in energy consumption and poor in strength.

Description

technical field [0001] The invention relates to a tool in the field of construction, in particular to a spiral ground pile used in the Gobi Desert landform with many gravels, hard soil and other geology. Background technique [0002] Ground piles are widely used in engineering construction, and they are widely used in many fields such as house construction, railway engineering, and rural fence nets. Ground piles are the key to the load-bearing and stability of buildings. In order to be buried in the ground conveniently, the existing ground piles generally have a conical lower part and a continuous spiral piece is arranged on the top. In order to insert the screw pile into the ground, the screw pile is rotated and pressed down, which causes the screw blades to bite into and screw into the ground. Once the screw piles are inserted into the ground, the weight carried by the screw piles will be distributed from the helix blades into the ground below the helix blades. The spir...
