In the present utility model, through the arrangement of the horizontal hole 3, the construction period can be shortened and the working surface can be increased when constructing the tunnel, which facilitates the organization of rapid construction. When the tunnel enters the operation stage, it can be used as an entrance or ventilation shaft; through the water retaining cover 7 , the setting of the first clear water ditch 19, when the clear water in the mountain body seeps out from the top of the inner wall of the tunnel, the clear water will drip on the outer wall of the water retaining cover 7 and slide into the first clear water ditch 19, and the water on the inner wall of the tunnel will The clean water will flow directly into the first clear water ditch 19 and be collected and discharged through the first clear water ditch 19; at the same time, the water retaining cover 7 can also separate the clean water and sewage in the tunnel to avoid the mixing of clean water and sewage; through the second sewage ditch 11 When constructing the tunnel face, the sewage generated during the construction will flow into the second sewage ditch 11 and be collected and discharged through the second sewage ditch 11; through the setting of the first drainage mechanism, the reverse slope tunnel can be The clean water in the first clear water ditch 19 of 2 is discharged from the first clear water ditch 19 to the outside of the reverse slope tunnel 2; through the setting of the second drainage mechanism, the sewage in the second sewage ditch 11 of the reverse slope tunnel 2 can be discharged from the first The clear water ditch 19 is drained out of the reverse slope tunnel 2; through the setting of the opening and closing mechanism, the first drainage mechanism can be easily installed or dismantled in the reverse slope tunnel 2.

To further optimize the solution, the opening and closing mechanism includes a baffle 12. A number of first transverse holes are sequentially opened on both sides of the bottom of the water shield 7 along the length direction. The baffle 12 is hinged with the inner wall of the water shield 7 through hinges and is connected with the inner wall of the water shield 7. The first transverse holes are arranged correspondingly. The inner wall of the water retaining cover 7 is provided with first transverse grooves corresponding to the first transverse holes one by one along the length direction. The first transverse grooves are located below the first transverse holes. A telescopic rod 13 is fixedly connected to the inner wall of the first transverse groove away from the baffle 12. A pressing rod 15 is fixedly installed at the end of the telescopic rod 13. The end of the pressing rod 15 can be located outside the first transverse groove. The telescopic rod 13 is sleeved with There is a first spring 14. Both ends of the first spring 14 are fixedly connected to the first transverse groove and the pressing rod 15 respectively.

The pressing rod 15 is A plug-in slot is provided at the top. The plug-in slot is adapted to the plug-in rod 16 and is located on the side of the plug-in rod 16 away from the telescopic rod 13 .

Because the drainage direction of the normal slope tunnel 1 is the same as the direction of the longitudinal slope of the tunnel, and the drainage direction of the reverse slope tunnel 2 is opposite to the direction of the longitudinal slope of the tunnel, therefore during construction, the water in the normal slope tunnel 1 can follow the direction of the normal slope tunnel 1. The longitudinal slope flows out of the normal slope tunnel 1, while the water in the reverse slope tunnel 2 will not flow out of the reverse slope tunnel 2 along with the longitudinal slope of the tunnel 2. Therefore, it is necessary to install a first drainage mechanism in the reverse slope tunnel 2; Internal pressure moves the pressing rod 15 on the water shield 7 in the reverse slope tunnel 2. After pressing for a certain distance, the plug-in slot will be located directly below the plug-in rod 16. At this time, the plug-in rod 16 will fall under its own gravity. into the plug-in slot, and the falling plug-in rod 16 will break away from the first groove, thereby ending the locking of the baffle 12, and opening the baffle 12, you can enter the first transverse hole of the reverse slope tunnel 2 The first drainage mechanism is installed, so that the clean water in the first clear water ditch 19 of the reverse slope tunnel 2 can be discharged from the reverse slope tunnel 2 with the help of the first drainage mechanism, and pumped into the first clear water ditch of the horizontal tunnel 3 Within 19.

To further optimize the solution, one end of the plug-in rod 16 located in the first transverse groove is fixedly sleeved with a limit block 18.

The end of the spring 17 is fixedly connected to the top of the first transverse groove.

After pressing the pressing rod 15, although the plug-in rod 16 will fall into the plug-in slot under its own gravity, there will be a certain friction between the plug-in rod 16 and the water shield 7, and the tunnel The dust inside may also fly into the sliding friction between the plug-in rod 16 and the water-shielding cover 7, thereby increasing the friction between the plug-in rod 16 and the water-shielding cover 7. When the friction force is greater than the plug-in rod 16 When the gravity is strong, the plug-in rod 16 cannot fall smoothly, and the baffle 12 cannot be opened. However, through the setting of the second spring 17 and the limit block 18, the downward force can be continuously provided for the plug-in rod 16. It can ensure that the plug-in rod 16 is smoothly inserted into the plug-in slot, ensuring the normal operation of the construction work and improving the efficiency of the construction work.
