Laiwu Jinda waterproof board manufacturers analyze common diseases tunnel waterproofing and drainage tunnel seepage water which is one of the common diseases of domestic and tunnels, according to statistics, which affect operations due to water leakage accounts for about 30% of the tunnel. Mainly for tunnel seepage water leaking arch, side wall Tangshui, construction joints and Deformation and concrete cracks leak water, surface water end of the tunnel and the tunnel bottom mud pumping like. Since the tunnel seepage water, increasing the humidity of the air in the tunnel, causing damage to communications, lighting and other facilities, resulting in road tunnels Frothing mud, also accelerated the speed of lining concrete carbonation, particularly corrosive groundwater, undermining the structural concrete, reducing the life of the tunnel, directly threatening the use of function of the tunnel. Therefore, make sure that the tunnel project quality, eliminate fundamentally tunnel disease and increasing the life of the target tunnel, choose a good waterproof material and correct tunnel waterproofing construction method is the key to success, we are familiar with the design drawings, to fully understand the intent and Drainage Design Designed according to the "row-based, cross-sectional, lead, blocking the combination of local conditions, comprehensive management" construction principles, in addition to design and layout of drainage facilities, also in ground water in many places additional drainage facilities, water board construction and Critical Control Point and inspection.
