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 noise cannot disturb residents. The problems that existing virtual pile head girdling breaking is tedious in construction and noise disturbs residents are solved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for eliminating virtual pile heads without ring cutting. Background technique [0002] In order to meet the requirements of ultra-high and large-span modern buildings, the building foundations are mostly in the form of pile foundations. In the process of pile foundation construction, as the direct connection with the main body, the treatment of virtual pile heads is particularly important. The traditional virtual pile head treatment plan is to overfill the pile foundation to a certain height during the construction of the pile foundation. After the pile foundation concrete is finally set, it will be cut along the foundation elevation line, and the concrete outside the reinforcement will be broken and stripped. Then, holes will be drilled around the pile foundation. Apply evenly, expand the pile head concrete to form a ring cut section, and then...
