Metro Shield Tunneling Construction Solution

Solution Background

With the rapid development of urban rail transit, shield tunneling has become one of the most widely used construction methods for metro and underground tunnel projects. Complex geological conditions, high groundwater pressure, and long-distance excavation require reliable chemical materials with outstanding performance. Wuhan Huadingcheng New Material Co., Ltd. provides comprehensive solutions including Tail Seal Grease, TBM Foam Agent, Main Bearing Seal Grease and Shield Lubricating Grease to ensure safe, efficient and continuous tunneling operations.

Project Challenges

01 High Groundwater Pressure

High groundwater pressure may lead to tail seal leakage, causing grout loss, water ingress and reduced construction safety.

 

02 Complex Geological Conditions

Different geological formations such as soft soil, sand, gravel and hard rock require customized conditioning agents and lubrication solutions.

 

03 Long-distance Continuous Excavation

Long-distance tunneling places higher demands on sealing systems and bearing lubrication to ensure uninterrupted operation.

 

04 Equipment Wear & Maintenance Cost

Heavy-duty operation accelerates wear of key components, increasing maintenance costs and downtime.

 

05 Environmental Requirements

Modern tunneling projects require environmentally friendly materials with high efficiency and stable performance.
