Recently, many friends have consulted the construction to share: do you know the relevant problems of grouting foundation reinforcement construction, in view of this, we have sorted out the relevant content, I hope it will be helpful to you.
Grouting reinforcement is a commonly used method of reinforcement of civil engineering structures, which is suitable for various engineering structures, such as bridges, buildings, foundations, etc. The construction process of grouting reinforcement includes preliminary investigation, design plan determination, material preparation, grouting equipment configuration, construction site layout and other links. The following is a detailed introduction from the concept, preliminary survey and construction.
Concept: Grouting reinforcement is a method of reinforcing soil or engineering structures by injecting high-strength grout or concrete. By pouring grout or concrete in the stressed area, the cavities in the soil can be filled, the compactness and bearing capacity of the soil can be improved, and the strength and stability of the soil can be enhanced.
Preliminary investigation: Before the grouting reinforcement construction, it is necessary to conduct preliminary investigation, which mainly includes the following links:
1. Positioning survey: determine the construction scope and reinforcement area, including soil properties, geological conditions, groundwater conditions, etc.
2.Permeability test: The diffusion and curing effect of the grouting material in the soil are determined by the permeability test.
3.Load test: According to the load requirements of the engineering structure, the load test is carried out to determine whether grouting reinforcement is required.
4.Environmental Assessment: Assess whether the construction environment is suitable for grouting reinforcement construction, including the environmental factors surrounding the construction site.
Construction:
The construction of grouting reinforcement includes the following key links:
1. Determination of the design scheme: according to the preliminary survey results and engineering requirements, the design scheme of grouting reinforcement is determined, including the selection of grouting materials, grouting depth and construction methods.
2.Material preparation: Prepare the slurry or concrete required for grouting to ensure that the quality of the material meets the standard.
3.Grouting equipment configuration: Configure grouting equipment, including grouting pipelines, pump trucks, mixers and other equipment.
4.Construction site layout: Layout at the construction site to determine the construction area, equipment placement, safety protection, etc.
5.Grouting construction: According to the design plan, the grout or concrete is injected into the soil through the grouting equipment to ensure uniform and dense grouting.
6.Construction acceptance: After the completion of construction, the acceptance is carried out to check whether the reinforcement effect meets the design requirements.
Grouting reinforcement is an effective method of reinforcement of civil engineering structures, which can effectively improve the stability and bearing capacity of engineering structures through the scientific planning and operation of the preliminary investigation and construction process.
