Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a rotary digging pile construction device and a construction method. BACKGROUND

[0002] Rotary digging pile refers to a pile type constructed by a rotary drilling machine. Since the operation is performed by a machine, the number of workers required is not high, and a large amount of labor cost can be saved. The common rotary digging pile construction process is as follows: pile position line laying, drilling machine positioning, buried protection cylinder, drilling into a hole, drilling and soil removal (including slag soil transportation), hole cleaning and inspection, transportation and installation of reinforcement cage, pouring of concrete, and pulling out of the cylinder to form a pile.

[0003] When lowering the reinforcement cage, the experience of the construction personnel is relied on to adjust the reinforcement cage to avoid deviation. In the previous pile construction technology, when the rotary digging machine forms a hole, the workers directly operate the protection cylinder, reinforcement cage, lattice column, steel pipe column, etc. at the hole opening. Not only can the vertical state of the above-mentioned building equipment during the construction process be ensured, but the danger coefficient of the workers is also increased.

[0004] Therefore, the prior art usually arranges and installs a positioning device around the pile hole before the building equipment is lowered to limit the building structure, so as to avoid deviation of the structure. However, the above-mentioned limiting structure usually needs to make the surrounding land in a horizontal state before use.
