Today I would like to recommend to you a related introduction to how to deal with the construction of foundation compacting grouting reinforcement, if you are interested in this, you can learn about it.
Foundation compacting grouting reinforcement construction is a commonly used foundation treatment method, which increases the bearing capacity of the foundation and improves the stability of the foundation by injecting high-strength cement slurry. The following is an in-depth analysis of the foundation compacting grouting reinforcement construction from the perspectives of construction process, scope of application, advantages and precautions.
1. Construction process:
1) Foundation preparation: clean up the debris on the surface of the foundation to ensure that the construction area is dry and flat.
2) Foundation drilling: According to the design requirements, drill and drill, the hole diameter and hole spacing are determined according to the design requirements.
3) Grouting construction: inject high-strength cement slurry into the borehole, and ensure that the grout evenly fills the hole during the grouting process to achieve the reinforcement effect.
4) Compacting treatment: After the grouting is completed, a special press is used to compact the grouting hole to increase the bearing capacity of the foundation.
5) Follow-up treatment: Repair the foundation surface and bring it back to flatness.
2.Scope of application:
The foundation compacting grouting reinforcement construction is suitable for all kinds of soil foundations, especially suitable for soft soil areas and unstable foundations at the bottom. This construction method is suitable for various foundation types, such as shallow foundations, deep foundations, and foundations that are subjected to different loads.
3.Related Features::
Improve the bearing capacity of the foundation: After grouting, the cement slurry solidifies in the hole of the foundation to form a high-strength filler, which can improve the bearing capacity of the foundation.
Long-lasting reinforcement: The compacted foundation can remain stable in long-term use and has good durability.
Simple construction: The whole construction process is relatively simple, does not require a large number of equipment and materials, and the construction period is short.
Environmentally friendly: Cement is a common environmentally friendly material, which will not produce pollution during the grouting process and has little impact on the surrounding environment.
4.Notes:
The ratio of grouting slurry should be reasonable to ensure the uniformity and fluidity of the slurry.
Ensure that the grouting point during construction is well sealed to prevent slurry loss.
Control the hole spacing and hole diameter of the grouting hole according to the design requirements to ensure the construction effect.
Strictly control the grouting pressure to avoid foundation damage caused by excessive pressure.
Before construction, necessary geological survey and design should be carried out to ensure the scientificity and feasibility of the construction plan.
The foundation compacting grouting reinforcement construction can improve the bearing capacity and stability of the foundation by injecting high-strength cement slurry. Its construction process is relatively simple, suitable for different types of foundations, and has a long-lasting reinforcement effect and good environmental friendliness. When implementing construction, it is necessary to pay attention to factors such as grout ratio, hole tightness and grouting pressure to ensure the construction effect.
