Method for manually lowering overweight reinforcement cage of hole digging pile
The invention discloses a method for manually lowering an overweight reinforcement cage of a hole digging pile. The method comprises the steps that a steel-tube square frame is manufactured; U-shaped necks are arranged, a first stiffening hoop is manufactured, and longitudinal main reinforcements of the reinforcement cage are welded to the first stiffening hoop; nylon ropes are fixed on the steel-tube square frame, and the first section of the reinforcement cage is horizontally placed on the nylon ropes; the first section of the reinforcement cage is gradually bound upwards; lowering is conducted on the reinforcement cage through the nylon ropes on the lower portion; the next section of the reinforcement cage is bound continuously till the bottom of the reinforcement cage reaches the designed depth. According to the method for manually lowering the overweight reinforcement cage of the hole digging pile, the problems that the lifting range of hoisting equipment is difficult to cover the pile foundation position, the hoisting equipment is difficult to be in place, the hole digging pile is blocked by inner support beams over the hole digging pile, and the reinforcement cage can not be lowered or is difficult to lower are solved, two workers are only needed to complete manufacture and lowering of the reinforcement cage, and the engineering cost is reduced.
