Product Introduction
The shield tail sealing brush is one of the key components of a tunnel boring machine (TBM). Its core function is to, during the TBM excavation process,
A continuous, flexible, and reliable sealing barrier is formed between the shield tail shell and the tunnel segment.
Prevent external water, soil, grouting slurry, and other materials from entering the tunnel interior, ensuring construction safety, efficiency, and the stability of the tunnel structure.
We fully understand the uniqueness of each project, which is why we offer comprehensive customized services tailored to your shield machine model, geological conditions, and specific requirements.
We offer the most suitable sealing brush solutions in terms of wear resistance, compressive strength, and sealing reliability.
Our products have been widely used in urban subways, railway and highway tunnels, cross-sea and cross-river tunnels, municipal utility tunnels, hydraulic engineering projects, and other fields. Our customers are located in major cities across China.
It is also exported to global markets including the Americas, Europe, Southeast Asia, and the Middle East, and has established strong partnerships with numerous large construction groups and tunnel-boring machine manufacturers.
