| description | According to the construction method for removing the virtual pile head without girdling breaking, a high-pressure jet grouting machine is used for spraying a concrete retarder to the position of the pile head needing to be cleaned, the retarder reacts with the pile head concrete, the setting time of the pile head concrete is delayed, pile foundation concrete below the pile head concrete is not affected, and the pile head concrete is prevented from being damaged. After the lower pile foundation concrete is finally set, the pile head concrete is not finally set, so that the pile head concrete is convenient and efficient to clean and chiseled away, manual circular cutting of the pile head and stripping of pile foundation main reinforcements are not needed, the pile head concrete chiseling construction is small in manual demand, simple in procedure and high in working strength, meanwhile, dust and noise cannot be generated in the breaking process, and the construction cost is reduced. And the environment and noi |
