某公路隧道防排水设计与施工质量控制

隧道防排水设计以"防、排、堵、截相结合"为原则,达到排水通畅、防水可靠、经济合理、不留后患的目的;在保证隧道防排水效果的前提下,加强防水、堵水措施,尽量减小隧址区地下水的流失、避免对水文地质环境造成重大影响。依据某隧道实际水文地质情况,计算该隧道的理论涌水量后,进行了防排水设计,在施工过程中采取有效的防排水措施,加强防排水施工过程控制,有效地保证了防排水的施工质量。

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.
