Abstract

The invention discloses a construction method for a semi-circular pile of a covered and excavated station. The construction method for covering and digging the semicircular piles of the station comprises the following steps that pile position lofting is conducted on fender posts, and positioning holes are formed in the ground according to the structures of the fender posts; a reinforcement cage is prepared, and in the reinforcement cage, part of reinforcing steel bars protrude in the radial direction to form a semicircular reinforcement cage with an arc-shaped outline; bamboo plywood is arranged, and the bamboo plywood is connected to the semicircular rib cage; a reinforcement cage is put down to be inserted into the pile hole; concrete is poured into the reinforcement cage and solidified; arranging a top beam and a retaining wall, and excavating earth; and the bamboo plywood is dismantled to obtain the semicircular pile. In the whole construction process, only materials such as bamboo plywood and steel bars which are easy to purchase and low in price need to be input, so that the cost input is reduced, and the economical efficiency of the whole project is improved. Meanwhile, the bamboo plywood is easy to detach, noise is greatly reduced, the requirement for green construction is met, and the problems that semicircular pile construction is troublesome and engineering quality is difficult to guarantee are solved.

Description

technical field [0001] The invention discloses and belongs to the technical field of building construction, and in particular relates to a construction method for covering and excavating semi-circular piles in a station. Background technique [0002] The enclosure piles of the cover and excavation station include semi-circular piles and round piles, and the upper part of the enclosure piles is designed as a semi-circular pile. [0003] In the current construction process, the enclosing piles are poured into a circle as a whole, and then the upper part is formed into a semi-circular pile by manual breaking. Then, when the half-pile is demolished in the foundation pit, it is difficult to control the flatness of the base surface due to the cumbersome process and the difficulty in accurately controlling the demolition range. At the same time, the construction efficiency is low and the overall construction cost is high. In addition, the position of the half-width reinforcement c...
