During this time, many friends have consulted about the topic of what the foundation compacting grouting reinforcement is for, and I took this opportunity today to sort out the relevant introduction, hoping to help you.
Ground compacting grouting reinforcement is a commonly used technique in civil engineering to strengthen the bearing capacity and stability of foundations. It is used by injecting a specific curing material (usually cement slurry, polymer slurry or chemical) into the foundation to fill the pores, increase the compactness and strength of the foundation, thereby improving the bearing capacity and settlement resistance of the foundation.
Conceptually, foundation compacting grouting reinforcement is a method to improve foundation conditions using grouting technology. It is suitable for a variety of civil engineering structures, including large buildings, bridges, reservoirs, subway tunnels, etc. By reinforcing the foundation, the problems of foundation settlement, differential settlement, and foundation instability can be solved to ensure the safety and stability of the structure.
Preliminary investigation is required before the implementation of foundation compacting and grouting reinforcement. The investigation work includes geological survey, foundation investigation and soil test. The main purpose of geological survey is to determine the underground geological structure, stratum properties and foundation conditions, as well as to judge the risk of geological disasters such as foundation consolidation settlement and **. The purpose of foundation investigation is to understand the conditions of the foundation, the bearing capacity of the foundation, the settlement of the foundation and other parameters. The soil test obtains data on the physical and mechanical properties and engineering properties of the soil by means of sampling and experiments, which provides a basis for the design of the grouting reinforcement scheme.
In the construction stage, the foundation compacting grouting reinforcement is usually carried out by drilling and grouting method. The specific operation includes drilling, hole cleaning, grouting and other steps. According to the design requirements, the hole is drilled at the appropriate position of the foundation, and then the hole cleaning operation is carried out to remove the soil layer and debris in the borehole to provide a channel for grouting. Grouting is carried out by injecting solidified material, filling pores, and reinforcing the foundation.
Ground compaction grouting reinforcement is a technology that improves foundation conditions by injecting solidified materials. Geological surveys and soil tests are required prior to implementation to understand the condition of the foundation and determine the grouting plan. The construction phase is carried out by means of borehole grouting and casting. This technology is suitable for various civil engineering structures, which can improve the bearing capacity and stability of the foundation and ensure the safety and stability of the structure.
