Jet grouting is an advanced technique used in soil stabilization and the creation of special foundations in complex geotechnical contexts. It is a fast and effective method that improves the mechanical properties of the soil, such as strength and permeability, through the injection of a high-pressure cementitious mixture (250-650 bar). This technique forms columns of stabilized soil, called "Soilcrete," directly in situ, significantly enhancing the properties of the treated soil.
Jet grouting is used in various geotechnical fields, including underground and open excavations, as structural support, waterproofing of foundations and walls, and soil improvement for tunnels and existing structures. Precision in controlling the flow and pressure of the injection fluid is crucial to ensuring the effectiveness and efficiency of the treatment, making the use of specific and customized equipment essential.
The Objective: Precisely Regulate Pressure and Flow
A client in the jet grouting sector urgently needed a customized pump capable of precisely regulating the flow and pressure of their system. This requirement was fundamental to ensure the quality and consistency of soil treatment. The solution needed to be developed quickly and seamlessly integrated into their existing system.
The Solution: A Combination of Hydraulic Components to Create a Customized Pump
Interfluid was engaged to provide a tailored solution that met these specific needs. The approach was divided into three main phases:
1. Creating the Diagram
The first phase involved creating a detailed diagram that defined the technical specifications and required functionalities for the customized pump. This diagram was the starting point for the entire project, ensuring that all components were correctly integrated and that the final solution was perfectly aligned with the client's needs.
2. Designing the Customized Pump
The second phase involved the detailed design of the pump. Customization involved combining high-quality components provided by Interfluid's partners, ensuring that each element contributed to the optimal functioning of the system.
3. Manufacturing and Testing
Finally, the pump was manufactured and subjected to internal and then client testing to ensure it met their operational and performance requirements.
Components Used to Create the Pump for Jet Grouting Systems
The customized pump was created by combining components from some of our partners:
- Kawasaki K3VL Axial Piston Pump: This pump, equipped with Atos RZME proportional valves, ensured high efficiency and reliability, as well as precise flow and pressure control
- EliXir® MP Filtri Filter: Ensured proper filtration of the fluid necessary for the booster pump, guaranteeing the correct functioning of the proportional flow control over time;
- Atos E-BM-AS Electronic Regulator: Provided advanced electronic control, improving the overall effectiveness of the system. The use of programming software also guarantees the possibility of customizing settings and providing remote support if needed.
Results and Benefits Achieved
The provided solution enabled the client to achieve precise and reliable control of flow and pressure, improving the quality of soil treatment and operational efficiency. The customized pump proved to be a critical component for the success of jet grouting operations, allowing the client to perform soil consolidation interventions with greater precision and safety.
This specific case demonstrates how a customized approach and the integration of high-quality components can solve complex technical challenges in the jet grouting sector. Thanks to the collaboration with expert partners and a rigorous design and testing process, Interfluid provided an effective and innovative solution in record time, contributing to the success of the client's operations.
This experience highlights the importance of tailored solutions and collaboration with specialized suppliers to address technical challenges in the advanced fields of geotechnics and civil engineering.
