Through the exchanges with many netizens in the past few days, many friends have asked about the topic of foundation grouting reinforcement and reinforcement technical regulations, and this article will introduce the places that everyone is more concerned about.
The technical specification for foundation grouting reinforcement refers to a set of normative documents for the reinforcement of buildings, bridges, dams, tunnels and other projects after the investigation and analysis of buildings, bridges, dams, tunnels and other projects. The regulations include survey, design, and reinforcement methods.
1. Survey stage:
Before the foundation grouting reinforcement can be carried out, survey work is first required. The contents of the investigation include the current situation of the infrastructure, the stress situation, the existing problems and possible hazards. At the same time, it is also necessary to investigate the geological environment, groundwater conditions, carrying capacity, etc. Through the survey, the necessary basis for design and reinforcement work can be provided.
2.Design Phase:
The design stage is a key part of the grouting reinforcement of the foundation. The design should determine the reinforcement scheme according to the survey results, including the reinforcement material, the grouting scheme, the location and depth of the grouting hole, etc. The design should be carried out in accordance with the relevant standards and specifications to ensure that the reinforcement effect meets the requirements. At the same time, the design should consider the overall stability and durability of the reinforced structure.
3.Reinforcement Method:
The main method of foundation grouting reinforcement is to increase the bearing capacity and crack resistance of the foundation by injecting specific materials into it. Commonly used grouting materials include cement slurry, polymer slurry, etc. When grouting to ensure that the material is fully soaked in the foundation, filled with cracks and voids, and forms an integrated structure. After reinforcement, it is also necessary to detect and monitor the reinforcement effect to ensure the quality of reinforcement.
The technical specification for foundation grouting and reinforcement is an important document for the standardized management of the foundation grouting and reinforcement engineering process, covering many aspects such as survey, design and reinforcement methods. Complying with the regulations ensures that the reinforcement effect meets the requirements and improves the safety and durability of the structure.
