Abstract

The invention provides a grouting reinforcement and rectification method suitable for a high-rise building structure. The method comprises the steps from S10 to S30, wherein in the step S10, grouting filling reinforcement is conducted on an original cushion layer under an original concrete valve plate, and the original cushion layer and grout are solidified to form a cushion layer reinforcement and strengthening layer; in the step S20, after the cushion layer reinforcement and strengthening layer is formed, grouting filling reinforcement is carried out on an original foundation under the original cushion layer, and the original foundation and grout are solidified to form a foundation reinforcement platform; in the step S30, after the foundation reinforcement platform is formed, a plurality of pile foundation grouting holes are vertically formed in the lower surface of the foundation reinforcement platform at intervals, grout is injected into the pile foundation grouting holes to form an under-column pile foundation. The cushion layer reinforcement layer, the foundation reinforcement platform and the under column pile foundation form a three-dimensional supporting system in the mode that the layers are reinforced layer by layer from top to bottom; the purpose of building foundation reinforcement and lifting rectification integration is achieved, and the problems that a building is not uniform in settlement and a rectification foundation is lifted are successfully solved.

Description

technical field [0001] The invention relates to the technical field of building foundation reinforcement and deviation correction, in particular to a grouting reinforcement deviation correction method suitable for high-rise building structures. Background technique [0002] In order to prevent accidents such as settlement, inclination or even collapse after the building is completed, the underground of the building structure must be rammed and reinforced to form a supporting foundation before the construction of the upper housing structure. For example, the basic composition of the supporting foundation for the current high-rise frame building is as follows: the original foundation is first formed by the dynamic compaction method, then a sandstone cushion is laid on the upper surface of the original foundation, and finally a concrete valve plate is laid on the top of the sandstone cushion. However, in some cases, although the soil layer has been subjected to dynamic compacti...
