Recently, there are many people who pay attention to interpreting the pre-grouting reinforcement construction process for you, but there are not many people who may really understand.
Pre-grouting reinforcement construction technology is a commonly used engineering reinforcement method, and its characteristics, applications, construction technology and development trends are as follows:
1. Features.
The pre-grouting reinforcement technology has the following characteristics:
High efficiency: The pre-grouting reinforcement construction process uses pre-grouting materials, and the slurry is injected into the solid medium before construction, which can fully fill the void and improve the strength of the solid medium.
Flexibility: The pre-grouting reinforcement construction process can adjust the composition and injection method of the slurry according to the needs of different projects, and adapt to the reinforcement requirements of different projects.
Economy: The pre-grouting reinforcement construction technology adopts the mechanized construction method, which is easy to operate, can quickly complete the reinforcement operation, and improve work efficiency.
Good long-term effect: The pre-grouting reinforcement construction process can effectively improve the compressive, shear and punching resistance of the solid medium, and increase its overall stability and durability.
2.Apply.
The pre-grouting reinforcement construction technology is widely used in the following engineering fields:
Civil engineering: such as reinforcement and repair of bridges, tunnels, foundations, slopes, etc.
Mining engineering: such as safety reinforcement and support of roadways, tunnels and goafs.
Water conservancy engineering: such as the reinforcement and seepage prevention of dams, embankments, rivers, etc.
3.Construction technology.
The pre-grouting reinforcement construction process generally includes the following steps:
Engineering preparation: including survey and design, material preparation, construction plan formulation, etc.
Hole excavation: According to the design requirements, excavate a certain number, position and size of openings in the solid medium.
Slurry injection: The pre-prepared slurry is injected into the solid medium through the hole, and the slurry fills the void of the solid medium and solidifies.
Verification and acceptance: Verify and accept the reinforced project to ensure the quality and effect of construction.
4.Trends.
