For people in the industry, the common problems of foundation settlement grouting reinforcement know what is going on with this, but for people in other industries, they don't know much about it, so let's introduce it below.
Ground settlement grouting reinforcement is a common foundation reinforcement method, which changes the physical properties of foundation soil by injecting specific materials (such as cement slurry, polyurethane, epoxy resin, etc.), reduces the degree of foundation settlement, and improves the bearing capacity of the foundation. The following is an in-depth analysis of the production process, advantages and application of foundation settlement grouting reinforcement.
Production process: 1. Foundation investigation: Conduct detailed investigation of the foundation to be reinforced, including geological structure analysis, groundwater level determination, soil property testing, etc., to determine the reinforcement plan.
2.Design scheme: According to the survey results, determine the grouting reinforcement scheme, including the selection of grouting materials, the determination of grouting aperture and depth, etc.
3.Construction preparation: Prepare the equipment, materials and labor required for grouting construction, and take safety measures.
4.Drilling: According to the design requirements, drilling in the foundation soil, generally choose mechanical drilling or manual drilling.
5.Cleaning the hole: remove the debris and mud in the borehole to ensure the full penetration and solidification of the grouting material.
6.Grouting : Inject the selected grouting material into the borehole to control the grouting pressure and flow rate to ensure the uniform distribution of the material.
7.Curing: After the grouting material is fully cured, the subsequent foundation reinforcement work is carried out.
Advantages: 1. Efficient and fast: The grouting reinforcement method can quickly complete the foundation reinforcement work and save construction time.
2.Economical and practical: The cost of the grouting reinforcement method is relatively low, and it is suitable for a variety of foundation treatment needs, which can improve the overall bearing capacity of the foundation.
3.Environmentally friendly and sustainable: Choosing the right grouting material can meet the requirements of environmental protection and will not cause pollution to the surrounding environment.
4.Strong controllability: The grouting reinforcement method can control the strength and stability of the foundation reinforcement, and adjust the ratio of grouting materials and grouting parameters according to the specific situation.
Application: 1. Soil foundation reinforcement: For weak soil foundation, grouting reinforcement can increase the compactness and strength of the soil and improve the bearing capacity.
2.Building foundation reinforcement: For the foundation of old buildings, due to long-term settlement will lead to building tilting and cracks, grouting reinforcement can repair the foundation settlement problem and ensure the safety and stability of the building.
3.Soil and rock slope reinforcement: In the reinforcement of soil and rock slope, grouting can fill soil pits and cracks, increase the stability of the soil, and prevent the slope from landslide and collapse.
4.Tunnel and underground engineering reinforcement: Grouting reinforcement can improve the stability and safety of the project by filling holes and cracks, solidifying the underground space.
Ground settlement grouting reinforcement is an economical, practical, efficient, fast and controllable foundation reinforcement method, which has a wide range of application prospects in soil foundation and construction engineering.
