The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] The first embodiment of this application is:

[0020] Please refer to Figures 1 - 3 , where Figure 1 is the overall structural schematic diagram of the first embodiment of the present utility model; Figure 2 is the structural schematic diagram at the seamless steel pipe of the first embodiment of the present utility model; Figure 3 is the structural schematic diagram at the connection component of the first embodiment of the present utility model.

[0021] The present utility model provides a drainage structure for preventing water gushing in tunnel 101: including a drainage mechanism. The drainage mechanism includes tunnel 101, reserved tee 105, connection component 115, longitudinal drain pipe 103, seamless steel pipe 104, stabilizing component 116 and auxiliary drainage component 117. The connection component 115 includes drainage pipe 109 and intelligent pressure valve 110. The stabilizing component 116 includes fine aggregate protection layer 111 and waterproof board 112. The auxiliary drainage component 117 includes flexible spring water permeable pipe 113 and longitudinal double-wall corrugated drain pipe 114. Through the above-mentioned solution, the problem that the existing drainage structure directly and singly drains and guides the spring eye, resulting in excessive pipeline pressure, which will cause structural damage and cannot be used continuously, is solved.

[0022] For this specific embodiment, the tunnel 101 is provided with a spring 102 and an invert 106. Drainage side ditches 107 are provided on both sides of the invert 106. The reserved tee 105 is arranged below the tunnel 101. The connecting component 115 is arranged between the spring 102 and the reserved tee 105. The longitudinal drain pipe 103 is fixedly connected and communicated with the reserved tee 105 and is located below the reserved tee 105. The seamless steel pipe 104 is fixedly connected between the reserved tee 105 and one of the drainage side ditches 107. The stabilizing component 116 is arranged below in the tunnel 101. The auxiliary drainage component 117 is arranged above in the tunnel 101. The outer diameter of the seamless steel pipe 104 is φ40, which is slightly larger than the spring 102. When draining the tunnel 101, water gushes out from the spring 102, floods into the reserved tee 105 through the connecting component 115, is shunted through the longitudinal drain pipe 103 and the seamless steel pipe 104, the water pressure is reduced, and it flows along the longitudinal drain pipe 103, the seamless steel pipe 104 and the drainage side ditch 107 to the designated position for drainage. At the same time, the stabilizing component 116 reinforces the area around the spring 102 to prevent the emergence of new water gushing points. The auxiliary drainage component 117 serves as a backup drainage component to improve the reliability of the structure, and the swelling water-stop rubber 108 can prevent water leakage.

[0023] Among them, the drainage pipe 109 is fixedly connected between the spring 102 and the reserved tee 105. The intelligent pressure valve 110 is fixedly connected inside the drainage pipe 109. When water gushes from the spring 102, it is drained into the reserved tee 105 through the drainage pipe 109 for shunting to reduce the pressure. At the same time, the intelligent pressure valve 110 can control the size of the water flow, making it more convenient for shunting.

[0024] Secondly, the fine aggregate protective layer 111 is fixedly connected inside the tunnel 101 and is located above the reserved tee 105. The waterproof board 112 is fixedly connected to the fine aggregate protective layer 111 and covers the fine aggregate protective layer 111. When diverting the spring 102, the fine aggregate protective layer 111, the waterproof board 112 and concrete are used to reinforce the area around the spring 102, which can improve the structural firmness and effectively prevent the tunnel 101 from gushing water again.

[0025] Meanwhile, the flexible spring drain pipe 113 is fixedly connected inside the tunnel 101, and the longitudinal double-wall corrugated drain pipe 114 is fixedly connected inside the tunnel 101 and communicates with the flexible spring drain pipe 113. The outer diameter of the flexible spring drain pipe 113 is φ50. When draining water from the tunnel 101, the water seeping into the tunnel 101 seeps into the flexible spring drain pipe 113 and then flows into the longitudinal double-wall corrugated drain pipe 114, thereby enhancing the drainage capacity of the structure and improving the redundancy and reliability of the structure.

[0026] When draining the tunnel 101, water gushes out from the spring eye 102 and is diverted into the reserved tee 105 through the diversion pipe 109 to reduce the pressure by means of diversion. Meanwhile, the intelligent pressure valve 110 can control the size of the water flow, making it more convenient for diversion. Subsequently, at the reserved tee 105, the water is diverted through the longitudinal drain pipe 103 and the seamless steel pipe 104. The pressure of the water decreases and it flows along the longitudinal drain pipe 103, seamless steel pipe 104, and the drainage side ditch 107 to be discharged to a designated position. At the same time, the spring eye 102 is reinforced by using the fine aggregate protective layer 111, the waterproof board 112, and concrete, which can improve the structural firmness and effectively prevent the tunnel 101 from gushing water again. When draining water from the tunnel 101, the water seeping into the tunnel 101 seeps into the flexible spring drain pipe 113 and then flows into the longitudinal double-wall corrugated drain pipe 114, thereby enhancing the drainage capacity of the structure and improving the redundancy and reliability of the structure; the interface positions of the reserved tee 105 with the longitudinal drain pipe 103, the diversion pipe 109, and the seamless steel pipe 104 are all sealed with the expansion water-stop rubber 108. The expansion water-stop rubber 108 can prevent water leakage and avoid the problem that the existing drainage structure directly and simply diverts the spring eye 102, resulting in excessive pipeline pressure, which may cause structural damage and make it impossible to continue using. The effect of diverting the spring eye 102, reducing the structural pressure, and thus extending the service life of the structure is obtained.

[0027] The second embodiment of the present application is as follows:

[0028] Please refer to Figures 4 - 5 , where Figure 4 is the overall structural schematic diagram of the second embodiment of the present utility model; Figure 5 is that of the second embodiment of the present utility model.

[0029] On the basis of the first embodiment, the drainage structure for preventing water gushing in the tunnel 101 in this embodiment further includes a protection mechanism, and the protection mechanism includes a plurality of trench covers 201 and filter meshes 202.

[0030] Among them, a plurality of the trench covers 201 are fixedly connected above the drainage side ditch 107. The filter screen 202 is fixedly connected to the seamless steel pipe 104 and is located at one end far from the reserved tee 105. When in the inverted arch 106, the plurality of trench covers 201 block the drainage side ditch 107, which can prevent foreign objects from entering the drainage side ditch 107 and causing blockage. The filter screen 202 can prevent a large amount of dust from entering the seamless steel pipe 104 during normal times and causing blockage, achieving the effect of ensuring the normal use of the structure.

[0031] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
