摘要
在铁建设[2004]47号文《铁路隧道工程预算定额》中,洞内排水定额仅适用于采取治水措施后涌水量≤20 m3/h的情况,当采取治水措施后涌水量仍超过20 m3/h时,定额没有提供洞内排水费用的计算方法。此文针对隧道施工过程中出现大量涌水后施工排水费用的计算问题提出了处理方法。
In the TJS[2004] No. 47 document Budget Rating of Railway Tunnel Projects, the in -tunnel drainage norm only applies to the amount of gushing water ≤20 m^3/h after water rectification measures are taken. When the amount of the gushing water still exceeds 420 m^3/h after measures taken, the norm does not provide the method of computing the drainage fees within the tunnel. This article presents a treatment method for the construction drainage after the happening of great amounts of gushing water in course of tunnel construction
