Tests are carried out according to the main performance index requirement of shield tail sealing grease to analyze the performance of the product. This process usually requires establishing the scientific performance indicators of grease, such as: density, consistency (non-working cone penetration), pumpability, spreadability, adhesion, resistance to water flushing, and water sealing ability.

Upon analysis, we will provide feedback to improve product quality, and additional steps that that can reduce the possibility of major accidents during usage.

To analyze the performance of main-bearing sealing paste, we qualify the following attributes: density, consistency, pumpability, adhesion, water resistance and water pressure sealing using specialized equipment. In addition, a dynamic leakage test is conducted.

The ability of main-bearing sealant (HBW) in the operation of the TBM machine bearings to fill gaps formed due to rotation is crucial, especially when the TBM is excavating.

These tests allow for a more conclusive analysis of the resistance capabilities exhibited by the sealant during operation. The results of these tests and parameters are provided in a comprehensive evaluation report.

We will provide on-site debugging and guidance for tunnel consumables products throughout all stages of tunnel construction.

Especially in the initial stage of a tunnel project, the correct use of products and good parameter adjustment will often establish an important and valuable technical reference for the overall later excavation construction. This leads to consistency and improved safety in tunnel construction.

Selecting the correct ground improvement method for different layer can significantly improve construction efficiency. we provide relevant technical parameters and experimental programs for ground improvement solutions.

To significantly enhance construction efficiency, it is important to select the appropriate ground improvement method for different geological conditions. We engage in on-site discussions with clients to determine geological environment, provide relevant technical parameters, and offer experimental plans to facilitate this exchange.

Through data collected and tests conducted, it is possible to determine how to improve the flow plasticity of the excavated soil.

For detailed case studies, please contact us.

We provide on-site debugging, adjustment, application, and training services for our clients, which aim to facilitate seamless project implementation and effective management.

In addition, we provide consultations and conferences to address the concerns and questions raised by those involved in tunnel construction projects.
