Anti-drainage of a Highway Tunnel Design and Construction Quality Control

Designed to prevent drainage tunnel defense,row,block,cut-off combination principle,to achieve smooth drainage,water,reliable,economical,leaving troubles purpose;in ensuring the effectiveness of waterproofing and drainage tunnel under the premise of strengthening the water,water shut-off measures to minimize the loss of underground water tunnel site area,to avoid a significant impact on the hydrogeological environment.The paper based on the actual hydro-geological conditions of a tunnel,the theoretical calculation of the tunnel water inflow was conducted after the waterproofing and drainage design,construction process to take effective measures to prevent drainage,waterproofing and drainage construction to enhance process control,effectively ensure the waterproofing and drainage construction quality.
