在水利工程之中,我们常常会为了更好的进行输水工作或泄洪工作而穿山开挖封闭的输水道,这就是我们常说的水工隧洞。对于水工隧洞来讲,其除了要担负输水和泄洪工作之外,还要肩负着灌溉、排沙以及放空水库等工作。由此可见,水工隧洞在水利工程中有着十分重要的作用。 In water conservancy projects, we often carry out tunneling and excavation of closed waterways for better water conveyance or flood discharge work. This is what we often call hydraulic tunnels. In terms of hydraulic tunnels, in addition to carrying out water and flood discharge work, they also have to undertake such tasks as irrigation, sediment discharge and emptying reservoirs. Thus, hydraulic tunnel in water conservancy project has a very important role.
