Abstract

A spiral drilling machine for forming concrete pile has a drilling tool, which is composed of a hollow drilling rod with spiral blades, a drill bit with discharge outlet and arranged at lower end of said hollow drilling rod, and an external pipe coaxially connected to the upper part of said hollow drilling rod in sealed mode. Said spiral blades are fixed to the external surface of said external pipe.

Description

technical field [0001] The present invention relates to an auger for forming concrete piles. Background technique [0002] With the rapid development of the construction industry, construction projects have higher and higher requirements for foundation design and construction, so concrete piles are more and more widely used in high-rise buildings, bridges, ports and offshore constructions. In order to make the concrete pile meet the architectural design requirements such as deformation resistance and earthquake resistance, it is necessary to improve the shape and structure of the concrete pile so that it has a specific shape, while meeting the design requirements and saving the amount of concrete. In my Chinese patent, the patent No. is ZL02203243.6, and the title is called "Auger Drilling Machine for Forming Concrete Pile", which discloses a kind of auger drilling machine, which is provided with an inner grouting pipe in the hollow drill rod, and is connected with the drill...
