Many people have recently paid more attention to the introduction of grouting reinforcement foundation reinforcement, due to the abundant time today, we have prepared a relevant introduction below, I hope to help you.
Grouting reinforcement Foundation reinforcement, referred to as grouting reinforcement, is a commonly used foundation reinforcement technology, which makes the foundation strong and stable by injecting solidified materials (such as cement slurry, polymer slurry, etc.) into the foundation.
Definition: Grouting reinforcement refers to the use of grouting equipment to send specific curing material pressure into the foundation, fill the pores, increase the density of the foundation, so as to improve the bearing capacity and stability of the foundation.
Material properties: The grouting material is usually a flowable solid mixture, and the common grouting materials are cement slurry, polymer slurry, bentonite slurry, etc. These materials have the following properties:
1. Fluidity: The grouting material has a certain fluidity and can be transported to the target position through the grouting equipment.
2.High strength: The grouting material can form a high-strength solid after curing, which can improve the bearing capacity of the foundation.
3.Impermeability: The grouting material has good impermeability and can prevent moisture from penetrating into the interior of the foundation.
4.Controllability: The grouting material can be proportioned and the curing time can be controlled according to specific needs to adapt to different foundation conditions.
Reinforcement scheme: The specific scheme of grouting to strengthen the foundation is determined according to the specific situation of the foundation and the purpose of reinforcement. Generally speaking, grouting to strengthen the foundation can be divided into the following steps:
1. Foundation investigation: through survey and test analysis, determine the bearing capacity and stability of the foundation to formulate a reinforcement plan.
2.Preparation: Clean the surface of the foundation from debris and dirt to ensure that the grouting material can be fully filled into the foundation.
3.Grouting construction: select appropriate grouting equipment and materials for grouting construction, inject grouting materials into the foundation, and fill the soil pores.
4.Curing time: According to the requirements of the grouting material and the construction conditions, wait for the grouting material to solidify into a solid foundation. The curing time generally ranges from a few hours to a few days.
5.Testing and acceptance: After curing, the reinforced foundation is tested and accepted to ensure that the reinforcement effect meets the design requirements.
Grouting reinforcement is a commonly used foundation reinforcement method, which improves the bearing capacity and stability of the foundation by injecting solidified materials to fill the pores of the foundation. Its material properties include flowability, high strength, impermeability, and controllability. The reinforcement plan includes steps such as foundation investigation, preparation, grouting construction, curing time and inspection and acceptance.
