Abstract

The present invention proposes a foundation reinforcement method, comprising the following steps: S1, performing water source isolation treatment on the pre-reinforcement area; S2, drilling a plurality of vertically extending landfill holes in the pre-reinforcement area; Filling with asphalt; S4, performing dynamic compaction on the pre-reinforcement area; S5, leveling the pre-reinforcement area. The invention prevents the external water source from infiltrating into the foundation and causing the foundation to be soft by isolating the water source of the foundation; opening a landfill hole in the foundation and pouring asphalt, and the asphalt has plasticity after cooling, which can make the foundation soil have certain ductility.

Description

technical field [0001] The invention relates to the technical field of roadbed engineering, in particular to a foundation reinforcement method. Background technique [0002] During building construction, it is necessary to ensure that the foundation has sufficient bearing capacity, especially when constructing in coastal areas, because the foundation in coastal areas is generally soft ground, with high water content, poor permeability, and low bearing capacity, in order to ensure construction quality and avoid foundation collapse Subsidence, cracks and other problems caused by the need for reinforcement of the foundation. [0003] The current foundation reinforcement method mainly uses a dynamic tamping machine to tamp the foundation. However, when the existing dynamic tamping machine tamps the foundation with high water content, the efficiency is low, and the waste of working hours is serious, which affects the entire construction period. Contents of the invention [000...
