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.

Customized products for your project.

Safeguard every meter of excavation in critical projects with proven, reliable technology.

Main features

Comprehensive performance balance: Typically, a steel wire brush provides the primary seal, complemented by a steel plate structure that enhances support and wear resistance.
Addressing Complex Operating Conditions: The design goal is to better adapt to tunnel projects with frequently changing geological conditions.

Core features

Combining the advantages of wire brushes and steel plate brushes, and through material or structural integration, this design aims to achieve both excellent elastic sealing performance and superior mechanical wear resistance simultaneously.

Applicable operating conditions

Suitable for composite geological formations (where a tunnel section passes through multiple different rock and soil layers) or projects with complex operating conditions where single steel wire brushes or steel plate brushes alone cannot meet all requirements.

Composite shield brush

Specification Model: 200*120*240*27 Applicable Models: CCCC Tianhe, CRRC Equipment, China Railway Construction Heavy Industry Description: Used for the final stage.
