150MM WIDE WIRE SEAL BRUSH

产品详情

MAIN FEATURES：

The steel wires form multiple flexible sealing barriers. With the aid of injected tail seal grease, they prevent groundwater, sediment and simultaneous grouting slurry from intruding into

 the shield machine through the tail clearance.

CORE FUNCTIONS：

Good flexibility and superior sealing performance: The elasticity of steel wires enables better adaptation to clearance variations caused by shield machine attitude adjustment and 

segment installation. Excellent grease adhesion: The mesh structure facilitates the retention of tail seal grease to form a reliable oil seal.


APPLICABLE WORKING CONDITIONS：

Suitable for soft soil strata with high water and earth pressure and abundant groundwater, such as clay layers, silty sand layers and riverbed bottoms. It is the preferred sealing 

solution for tunneling of most urban subways and river-crossing tunnels.
