Abstract

The invention discloses a non-diffusion pile foundation construction method, which comprises the following steps: opening a reinforcement hole in the soil body near the barrel of the shield machine and the cutter head; covering a canvas bag with the reinforcement cage of the pile foundation, and the canvas bag includes the reinforcement reinforcement of the pile foundation The bottom of the cage and the outer circular surface of the pile foundation reinforcement cage; after the canvas bag at the bottom of the pile foundation reinforcement cage is opened through the pressure hole, put the bottom of the pile foundation reinforcement cage into the reinforcement hole; put the pile foundation reinforcement cage down After reaching the bottom of the reinforcement hole, seal the pressure hole and pour concrete for the pile foundation until the pouring is completed. By covering the reinforcement cage of the pile foundation with a canvas bag, it can effectively prevent the concrete of the pile foundation from spreading to the cutter head and the barrel of the shield machine. The structure is wrapped up, which increases the social and economic benefits, and can effectively guarantee the progress and safety of the project. The invention is suitable for pile foundation construction in which concrete diffusion is avoided.

Description

technical field [0001] The invention relates to a non-diffusion pile foundation construction method, which is suitable for some situations in which the pile foundation concrete is prevented from being mixed with the surrounding soil, and is particularly related to the need to control the pile body concrete diffusion and other structural isolation. Background technique [0002] In the shield tunneling construction, the construction of the shield machine opening and changing the tool is a construction process with high requirements for shield construction. Usually, the soil reinforcement operation will be carried out before opening the position and changing the tool. [0003] Reinforce the soil around the barrel of the shield machine and the cutter head. When pouring concrete for the pile foundation, the concrete is likely to spread to the area of ​​the cutter head and the barrel of the shield machine, causing the shield machine to be wrapped and affecting the subsequent shield...
