Jet grout pump for for building foundation
Jet grout pump has important application value in building foundation engineering, especially in situations where underground drilling operations are required to reinforce or repair foundation piles (such as pile foundations).
The following is a detailed introduction about Jet groove pump in the reinforcement or repair of building foundation piles and underground drilling work:
1、 The role and advantages of Jet grout pump
High pressure grouting: Jet grout pump can generate high pressure, injecting cement slurry or other grouting materials into the foundation soil at high speed to form a strong grouting pressure, ensuring that the grouting material can fully fill and penetrate around the pile body or into the formation cracks.
Significant reinforcement effect: By grouting, the bearing capacity and stability of the pile body can be significantly improved, the mechanical properties of the foundation soil can be improved, thereby reinforcing or repairing the foundation pile and extending its service life.
Strong adaptability: Jet grout pump is suitable for various geological conditions and engineering requirements, and can flexibly adjust grouting parameters to meet different engineering requirements.
2、 Application in the reinforcement or repair of foundation piles
Pile foundation reinforcement: For pile foundations with insufficient bearing capacity or existing defects, Jet grout pump can be used for grouting reinforcement. Grouting materials can penetrate into the surrounding soil of the pile, forming a composite foundation and improving the overall bearing capacity and stability of the pile foundation.
Reinforcement of soil around piles: During pile foundation construction, if there are weak layers or voids in the soil around the piles, Jet grout pump can be used for grouting treatment. Grouting materials can fill and consolidate these weak layers or voids, improving the strength and stability of the soil around the pile.
Underground drilling work: When conducting underground drilling operations, if encountering complex geological formations, difficult to drill holes, or the need to reinforce hole walls, Jet grout pumps can also play a role. By grouting treatment, drilling conditions can be improved, hole quality can be enhanced, and hole walls can be reinforced to prevent collapse.
3、 Precautions
Grouting parameter control: During the grouting process, it is necessary to strictly control parameters such as grouting pressure, grouting speed, and grouting volume to ensure the grouting effect and quality.
Selection of grouting materials: The selection of grouting materials should be determined according to engineering requirements and geological conditions, ensuring that the grouting materials have good fluidity and permeability, and can fully fill and penetrate into the target formation.
Equipment maintenance and upkeep: Regularly inspect and maintain the Jet grout pump and its supporting equipment to ensure that they are in good working condition, avoiding malfunctions or affecting the grouting effect during the grouting process.
