Novel construction technology for removing pile heads of bored piles

Abstract

The invention provides a novel construction technology for removing pile heads of bored piles. Bamboo plywood is arranged on the inner side and the outer side of a reinforcement cage, and must be fixed with main reinforcements firmly, so that the bamboo plywood is prevented from falling or sliding down into concrete of lower parts of the pile heads. Bonding between the concrete of the pile heads and the main reinforcements is avoided, when the pile heads are chiseled off after a foundation pit is excavated, the concrete is not stripped from the reinforcements, so that the chiseling speed of the pile heads is increased greatly, and construction cost is reduced. The novel construction technology for removing the pile heads of the bored piles has convenience and rapidness, namely the new technology is convenient to operate, the number of corollary equipment is small, the new technology is easily accepted by constructors, and the constructors can skillfully operate the new technology rapidly.

Description

technical field [0001] The invention relates to a new construction technology, in particular to a new construction technology for removing the head of a bored pile. Background technique [0002] The removal of the pile head of the traditional bored pile is to manually peel off the concrete that needs to be removed bit by bit. Since part of the main reinforcement extends into the concrete of the pile head, it is necessary to use equipment to further peel off the concrete around the steel bar, and then use it after all the steel bars are exposed. The hoisting equipment breaks and lifts the pile core (without steel bars). This construction method wastes labor, increases construction costs, and even damages the main reinforcement of the pile foundation and pile head concrete, and the construction speed is relatively slow. With the pile foundation construction using the partition method, the concrete at the pile head and the main reinforcement will not be wrapped. After the found...
