| Message: | Spring semicircle tube, also known as soft semicircle pipe, semicircle drainpipe, omega type soft semicircle drainpipe, it is specially used for tunnel application.
Spring semicircle pipe applies in tunnel non pressure drainage and ensures the tunnel inner structure permanent drainage unblocked, so as to make the tunnel lining structure of peripheral become no water pressure environment and ensure the tunnel no water leakage in using period. With acid and alkali resistance, penetration, soft and elastic, arbitrary bending, it is able to adapt to the surrounding gradually deformation characteristics. It can adapt to uneven surface of surrounding rock and fracture shape, avoid rock direct inflow of sediment caused by the blockage, withstand jet concrete impact without damage, no deformation. And it can eliminate the effect of tunnel external water pressure, improve lining structure stress condition. |
