Novel construction process for solving difficulty of pile sinking by holding and pressing

Abstract

The invention discloses a novel construction process for solving the difficulty of pile sinking by holding and pressing, and belongs to the technical field of static pressure pile sinking. The novel construction process specifically comprises the following steps that S1, a pile position is determined, specifically, according to a pile position arrangement diagram and a corresponding axis, a tapeline is combined with a theodolite, a pile hole is measured and positioned, the position is marked, and meanwhile, permanent mark points are made at the four corners of a site; and S2, materials enter the site, specifically, a prefabricated pile is unloaded to a designated position by a crane for stacking, specifically, a soil cleaning device is hoisted above the pile through the crane and then fixed to the upper part of the pile through a clamping mechanism, the soil cleaning device comprises an electric hoist assembly, a material conveying mechanism and the clamping mechanism, the electric hoist assembly is installed on the upper part of the clamping mechanism, and the material conveying mechanism is installed at the hoisting end of the electric hoist assembly. According to the novel construction process, when a dense coating is encountered during pile sinking, the soil cleaning device is inserted from the top end of the pile, sand in the pipe pile is cleared, the end resistance is reduced, and the pile is pressed while the soil is cleaned until normal construction is carried out.

Description

technical field [0001] The invention belongs to the technical field of static pressure pile sinking, and in particular relates to a new construction technology for solving the difficulty of holding pressure pile sinking. Background technique [0002] With the development of economy and society, human beings have more and more demands on the construction of high-rise buildings and long-span bridges. The foundation reinforcement technology has been the focus and focus of my country's civil engineering, transportation engineering and other fields in the past ten years. The static pressure pile reinforcement foundation is a new underpinning technology for building foundation reinforcement. Because the static pressure pile method uses prefabricated piles, the quality and integrity of the pile body are guaranteed, the process is simple, easy to operate, and the construction speed is fast. Vibration, no noise, small construction stress, no pollution to the environment, using the co...
