During this time, many friends have consulted the grouting process: what are the related topics of curtain grouting reinforcement, and I took this opportunity today to sort out the relevant introductions today, hoping to help you.
The grouting process is a commonly used method of foundation reinforcement to improve the physical properties of the soil or rock layer by injecting grout, thereby increasing its bearing capacity and stability. As a common form of grouting process, curtain grouting has the following functions.
1. Reinforcement of soil or rock formation: Curtain grouting can increase the overall strength and stiffness of soil or rock formation by injecting grout to form a continuous solid wall. In the soft soil layer, curtain grouting can effectively improve the shear strength and settlement resistance of the soil, and prevent the settlement and deformation of the foundation.
2.Prevent the dissolution and erosion of soil or rock layers: The slurry used in curtain grouting usually contains certain cementitious materials, which can improve the erosion resistance of the soil or rock layer, prevent water flow through the soil or rock layer, and reduce the permeability of the foundation. At the same time, the cementitious material in the slurry can fill the capillary pores in the soil or rock formation, hindering the penetration and diffusion of the dissolved solution.
3.Polymerization of loose soil or rock formations: The slurry added to curtain grout has a certain cohesiveness and cohesiveness, which can solidify loose soil or rock layers into a solid volume. This reduces the compressibility and settling of the soil, improving the stability and liquefaction resistance of the soil.
In addition to the above main functions, curtain grouting can also be used for foundation reinforcement in the following aspects.
1. Prevent the stability of the slope of the soil slope and the slope: for the slope or soil slope, the curtain grouting can form a uniform and strong soil structure to increase the stability and anti-skid performance of the slope.
2.Solve geological problems in underground engineering such as underground tunnels and caves: In underground engineering, curtain grouting can be used to strengthen the ground and surrounding rock to improve the stability and safety of underground engineering.
3.Reinforcement of pile foundation and wall: Curtain grouting can be used in combination with pile foundation or wall to improve the bearing capacity and stability of pile foundation or wall, and prevent settlement and damage of pile foundation or wall.
As a form of grouting process, curtain grouting improves the physical properties of the soil or rock layer by injecting grout to achieve the reinforcement and stability of the foundation. It has a wide range of applications in geoengineering, underground engineering and surrounding rock engineering.
