Traffic and drainage method for overhauling water delivery main tunnel
The invention discloses a traffic and drainage method for overhauling a main water delivery tunnel, which comprises the following steps: during normal operation of the main water delivery tunnel, a blocking gate is in a closed state, and a construction branch tunnel is blocked; when the water delivery main hole is in the overhaul period, firstly, the opening and closing valve of the overhaul pipe is opened, the water delivery main hole and the drainage pool are communicated, accumulated water in the water delivery main hole is emptied, and then the blocking gate is opened, so that personnel and vehicles reach the water delivery main hole through the overhaul platform and the overhaul channel for overhaul operation. According to the traffic and drainage method for overhauling the main water delivery tunnel, investment is low, the effect is good, the two functions of traffic overhauling and overhauling drainage can be achieved through blocking of the construction branch tunnel, overhauling management and operation maintenance of the main water delivery tunnel are facilitated, and the traffic and drainage method is particularly suitable for reconstruction of the overhauling branch tunnel of a long-distance and large-burial-depth pressure water delivery tunnel.
本发明公开了一种用于输水主洞检修的交通和排水方法，包括：输水主洞正常运行期间，封堵闸门为关闭状态，实现对施工支洞的封堵；输水主洞处于检修期，首先打开放空管的启闭阀，连通输水主洞和排水池，放空输水主洞内的积水，之后，开启封堵闸门，使人员和车辆通过检修平台和检修通道到达输水主洞，进行检修作业。本发明提供的用于输水主洞检修的交通和排水方法，投资低、效果良好，能够通过施工支洞封堵实现检修交通和检修排水两种功能，方便了输水主洞检修管理、运行维护，尤其适用长距离、大埋深的有压输水隧洞的改建检修支洞。
