Description
Technical Field
[0001] The utility model belongs to the technical field of secant piles, and particularly relates to a secant pile forming device. Background Art
[0002] A secant pile is a structure where adjacent concrete piles are partially embedded in a circular shape, and steel reinforcement cages are placed in the subsequent piles constructed alternately, forming an integral continuous waterproof and soil retaining structure with good anti-seepage effect.
[0003] For the existing secant piles, pile A needs to be constructed successively, with all pile As spaced apart from each other, and then pile B is constructed between every two pile As. The construction of pile B is completed after the initial setting and before the final setting of the concrete of pile A. Both pile A and pile B are constructed using a full casing drilling rig, which includes a rig body, a casing, and a cutting tool. The casing is slidably and rotatably connected to the rig body, and the cutting tool is fixedly arranged on the casing. When drilling, the rig body controls the casing to slide and rotate towards the ground direction, and the cutting ability of the cutting tool is utilized to drill during the movement. After drilling is completed, concrete is poured to complete the construction of pile A. Then, the cutting ability of the cutting tool is used to cut off the concrete at the intersecting part between adjacent pile As, and the steel reinforcement cage is placed and poured to achieve the secant.
[0004] During the pile forming process of the existing secant piles, since the sizes of pile A and pile B required for the pile foundation are different, different sizes of cutting tools need to be used to cut pile A during construction, so that pile B can be constructed between two adjacent pile As. This method requires selecting a cutting tool of an appropriate size according to the size of the pile foundation, resulting in a small applicability of the cutting tool, and a special pipe drilling rig is required for construction, which is rather inconvenient.
