[0002] Tunnel lining seepage is a common disease that often occurs in tunnels but is not easy to deal with thoroughly. In order to treat this disease, grooves are usually dug in the seepage-prone areas inside the tunnel and drainage pipes are buried. The drainage pipes will guide the seepage water into the tunnel's drainage system.
[0003] However, in the routine maintenance of tunnels in winter, especially when water seepage occurs in the tunnel, the seepage water is easy to freeze and block in the drainage pipe, and even freeze and swell to damage the drainage pipe, causing the tunnel lining to be damaged. Although the prior art discloses that electric heating tape can be applied to the drainage structure of the tunnel to ensure the normal operation of the drainage pipe, how to achieve uniform heating of the drainage pipe and how to quickly assemble the electric heating tape are still problems to be solved in this field.

[0041] like Figure 1 and Figure 5 As shown, this embodiment provides a heating tape drainage structure for preventing water seepage and frost heave of tunnel lining, comprising a drainage pipe 1 buried in the inner wall of the tunnel, two electric heating tapes 2 and a plurality of binding assemblies 3; the two electric heating tapes 2 are symmetrically applied to the drainage pipe 1, and the length direction of the electric heating tapes 2 is consistent with the length direction of the drainage pipe 1; the plurality of binding assemblies 3 are arranged at intervals on the drainage pipe 1, and the binding assemblies 3 are used to symmetrically attach the two electric heating tapes 2 to the drainage pipe 1.
[0042] The binding assembly 3 includes a bearing plate 301 and an elastic band 302, one end of the elastic band 302 is connected to one end of the bearing plate 301, and the other end of the elastic band 302 is connected to the other end of the bearing plate 301. Both ends of the inner side of the bearing plate 301 are provided with first limiting strips 303 arranged in parallel, and the bearing plate 301 and the two first limiting strips 303 form a first limiting groove 304. Two second limiting strips 305 arranged in parallel are provided on the inner side of the elastic band 302, and the elastic band 302 and the two second limiting strips 305 form a second limiting groove 306; when the bearing plate 301 and the elastic band 302 are connected in a ring shape, the first limiting groove 304 and the second limiting groove 306 are arranged oppositely. In one embodiment, the bearing plate 301 is made of an elastically deformable plastic material, and after the bearing plate 301 is sleeved on the drain pipe 1, it can be conformed according to the shape of the drain pipe 1 and the electric heating belt 2.
[0043] When the binding assembly 3 is sleeved on the drainage pipe 1 , the bearing plate 301 abuts against one of the electric heating tapes 2 , which is located in the first limiting groove 304 , and the other electric heating tape is located in the second limiting groove 306 .
[0044] This technical solution arranges two electric heating cables 2 symmetrically on the drain pipe 1. When the electric heating cables 2 are powered on, the drain pipe 1 can be evenly heated. Even when the temperature drops in winter, the phenomenon of ice blockage caused by water seepage in the drain pipe 1 can be quickly eliminated, avoiding the phenomenon of tunnel lining damage caused by frost heave damage to the drain pipe. At the same time, the design of the bearing plate 301, the elastic band 302, the first limiting groove 304 and the second limiting groove 306 facilitates the rapid arrangement of the two electric heating cables 2 symmetrically on the drain pipe 1, thereby realizing the rapid assembly of the electric heating cables. In addition, the design of the elastic band 302 allows the binding assembly 3 to be applied to drain pipes of various specifications, thereby improving practicality.
[0045] Specifically, the length direction of the first limiting strip 303 is perpendicular to the length direction of the elastic band 302, so that the two first limiting strips 303 can limit one of the electric heating tapes 2; the length direction of the second limiting strip 306 is perpendicular to the length direction of the elastic band 302, so that the two second limiting strips 306 can limit the other electric heating tape 2.
[0046] Secondly, the heating tape drainage structure for preventing the tunnel lining from water seepage and frost heaving also includes a water pipe 4 and a drainage ditch 5 provided on both sides of the tunnel bottom; one end of the drainage pipe 1 is connected to the water pipe 4 on the corresponding side through a connecting pipe, and the water pipe 4 is connected to the drainage ditch 5 on the corresponding side through a connecting pipe. The other end of the drainage pipe 1 is connected to the water pipe on the other side through a connecting pipe, and the water pipe on the other side is connected to the drainage ditch on the other side through a connecting pipe. The seepage water in the drainage pipe 1 enters the drainage ditch 5 through the water pipe 4 and is discharged.
[0047] Furthermore, in order to improve the heat preservation effect of the drain pipe 1, a heat preservation layer is provided on the outside of the drain pipe 1, the two electric heating cables 2 and the plurality of binding components 3. The heat preservation layer is made of rubber-plastic heat preservation material, which is convenient for construction workers to wrap around the drain pipe 1.
[0048] In addition, hooks 307 are provided on both sides of the other end of the supporting plate 301, and a connecting rod 308 is provided on the other end of the elastic band 302, and the connecting rod 308 is hooked on the two hooks 307 of the supporting plate 301. The hooks 307 of the supporting plate 301 cooperate with the connecting rod 308 of the elastic band 302, so as to facilitate the quick connection of the binding assembly 3 on the drain pipe 1. Moreover, the open end of the hook 307 is arranged to face inward. After the binding assembly 3 is connected to the drain pipe 1, the open end of the hook 307 is close to the outer contour of the drain pipe 1, and the outer contour of the drain pipe 1 has an obstructive effect on the connection rod 308 from detaching from the hook 307. Secondly, the open end of the hook 307 is designed to be closed, which can also effectively prevent the connection rod 308 from detaching from the hook 307. In addition, when the binding assembly 3 needs to be stored, in order to prevent the connecting rod of one binding assembly from being hooked on the hook of another binding assembly, the elastic band can be wrapped around the supporting plate to make the connecting rod 308 hooked on the hook 307. Figure 5 shown.
[0049] In order to facilitate the control of the electric heating tape 2 to heat the drainage pipe 1, the heating tape drainage structure for preventing the tunnel lining from water seepage and frost heaving also includes a controller and a temperature sensor; the temperature sensor is placed in the drainage pipe 1, and the temperature sensor is used to monitor the temperature in the drainage pipe 1. The temperature sensor and the two electric heating tapes 2 are electrically connected to the controller, and the controller receives the temperature data uploaded by the temperature sensor and compares the temperature data received by the controller with the built-in temperature threshold; when the temperature data received by the controller is greater than the built-in temperature threshold, the controller energizes the two electric heating tapes.
