Received some netizens of the news, there are many people for the backfill grouting reinforcement construction technical guidance does not know, the following is a related introduction to it, if you are interested, you can read it.
Backfill grouting reinforcement is a common civil engineering construction technology, which improves the mechanical properties and stability of the soil by injecting grouting materials into the soil. The following is an in-depth analysis of the production process, advantages and application of backfill grouting reinforcement.
1. Production process:
The production process of backfill grouting reinforcement mainly includes the following steps:
1) Soil preparation: clean and treat the soil to be strengthened to ensure that the surface of the soil is free of debris, clean and tidy.
2) Drilling: According to the design requirements, the soil is drilled, and arranged according to the hole diameter and hole spacing.
3) Concrete pulping: Mix cement, sand, water and other raw materials according to a certain proportion for pulping. During the pulping process, attention needs to be paid to controlling the fluidity, viscosity and stability of the slurry.
4) Grouting construction: the pulping material is injected into the borehole through the pumping equipment. During grouting, the grouting speed and pressure need to be controlled to ensure that the grouting material can fully fill the voids of the borehole and the surrounding soil. After the grouting is completed, it needs to be cured, and it generally needs to wait for a certain time for the slurry to solidify into a solid with high strength.
2.Advantages:
Backfill grouting reinforcement has the following advantages:
1) Improve the mechanical properties of the soil: the grouting material fully fills the borehole and the soil void, and forms an integral part with the surrounding soil, which can effectively improve the strength, stability and impermeability of the soil.
2) Wide applicability: Backfill grouting reinforcement is suitable for various soil layers and geological conditions, including sand, clay, rock, etc.
3) Short construction period: Compared with other reinforcement methods, the construction period of backfill grouting reinforcement is shorter, and the project can be completed quickly.
4) Relatively low cost: The backfill grouting reinforcement process is relatively simple, and the cost of raw materials is relatively low, which is relatively economical.
3.Applications:
Backfill grouting reinforcement has a wide range of applications in civil engineering, mainly including the following aspects:
1) Foundation reinforcement: Backfill grouting can be used to solve the settlement and instability problems of soil foundation, and improve the bearing capacity and stability of the foundation.
2) Slope reinforcement: The soil after grouting can increase the ability to resist landslides and effectively prevent the collapse and sliding of the soil.
3) Water conservancy engineering: backfill grouting can be used in water conservancy projects such as old embankment reinforcement, river channel improvement, and embankment reinforcement.
4) Underground engineering: grouting can improve the tightness and stability of groundwater engineering, and prevent groundwater intrusion and soil immersion.
Backfill grouting reinforcement is a common and effective civil engineering construction technology, which has the characteristics of simple production process, obvious advantages and wide application. In the actual project, it is necessary to carry out the construction scheme design and technical operation according to the specific situation to achieve the reinforcement effect and engineering requirements.
