[0037] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.
[0038] Example, refer toFigure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , which is an embodiment of the present utility model, provides an anti-icing structure for a corrugated steel plate sleeve lining in a tunnel, including a corrugated steel plate sleeve lining 14, a drainage conduit 1, a waterproof electric heating tape 2, and a drain pipe 3. The drainage conduit 1 is arranged outside the corrugated steel plate sleeve lining 14. The number of the drainage conduits 1 is multiple, and all the drainage conduits 1 are arranged along the axial direction of the corrugated steel plate sleeve lining 14. The side wall of the drainage conduit 1 is provided with a water inlet groove 4; the waterproof electric heating tape 2 is arranged inside the drainage conduit 1, and a through hole 5 is provided at a position corresponding to the water inlet groove 4 on the waterproof electric heating tape 2; there are drain pipes 3 on both sides in the tunnel, and the drainage conduit 1 is communicated with the drain pipe 3.
[0039] In this embodiment, multiple corrugated steel plate sleeve linings 14 are arranged along the width direction of the tunnel and spliced together to form an arch culvert. A plurality of drainage conduits 1 are arranged along the axial direction of each arch culvert. The left and right ends of the drainage conduit 1 are respectively communicated with the drain pipes 3 at the corresponding ends. The outer wall of the waterproof electric heating tape 2 is attached to the inner wall of the drainage conduit 1. Both the drainage conduit 1 and the corrugated steel plate sleeve lining 14 are made of metal and have good heat conduction effect. One end of the waterproof electric heating tape 2 is left with a power cord, and the power cord located outside the drainage conduit 1 is used to connect to an external power source. By energizing the waterproof electric heating tape 2 for heating, the metal drainage conduit 1 and the metal corrugated steel plate sleeve lining 14 can be heated. Utilizing the good heat conduction of the corrugated steel plate sleeve lining 14 and the drainage conduit 1, the leakage point part and the surrounding area of the tunnel can be heated, and the space temperature between the corrugated steel plate sleeve lining 14 and the tunnel inner wall can be changed, which can effectively prevent the leakage point in the tunnel from freezing and swelling due to water leakage. Moreover, when there is water accumulation in the tunnel, the water accumulation will flow through the water inlet groove 4 on the drainage conduit 1 and the through hole 5 on the waterproof electric heating tape 2 to the drain pipe 3 and be discharged out of the tunnel through the drainage ditch, which can effectively prevent the leakage water from accumulating and even freezing in the tunnel. The same ends of all the drainage conduits 1 are communicated with the same drain pipe 3, which can simplify the maintenance work of the drainage system.
[0040] The water inlet groove 4 can have various forms. The present utility model gives the following two forms:
[0041] First, as shown in Figure 5 , the water inlet groove 4 is a long strip-shaped notch penetrating the length direction of the drainage conduit 1, and the through hole 5 is also a long strip-shaped notch penetrating the length direction of the waterproof electric heating tape 2, so that the water in the tunnel can quickly pass through the through hole 5 and the water inlet groove 4.
[0042] Second, as shown in Figure 6As shown, the water inlet tank 4 has a mesh water seepage hole. The mesh water seepage hole can provide a large surface area, allowing more water to flow through, thereby improving the water inlet efficiency. The mesh design enables the water flow to be evenly distributed in different areas of the drainage conduit 1, avoiding local overload. The mesh water seepage hole can effectively block larger impurities and prevent them from entering the interior of the drainage conduit 1 and causing blockage.
[0043] Furthermore, as Figure 2 shown, the drainage conduit 1 is arranged in the trough of the steel corrugated plate lining 14. The water droplets dripping from the tunnel will naturally flow into the trough with a concave shape outside the steel corrugated plate lining 14. Installing the drainage conduit 1 and the waterproof electric tracing tape 2 in the trough of the steel corrugated plate lining 14 can not only reduce the laying area of the waterproof electric tracing tape 2, facilitate the replacement of the waterproof electric tracing tape 2, but also protect the drainage conduit 1 and the waterproof electric tracing tape 2, reducing the probability of damage to the waterproof electric tracing tape 2.
[0044] Furthermore, as Figure 1 、 Figure 3 、 Figure 9 and Figure 10 shown, it further includes a concrete foundation 6. The concrete foundation 6 is used to be arranged in the tunnel. The end of the steel corrugated plate lining 14 is arranged on the concrete foundation 6. The drain pipe 3 is arranged inside the concrete foundation 6.

The outlet end of the drain pipe 3 passes through the concrete foundation 6 and extends to the outside of the concrete foundation 6. The concrete foundation 6 is used to support the steel corrugated plate lining 14, which can ensure the stability and safety of the steel corrugated plate lining 14. The concrete foundation 6 can also protect the drain pipe 3 located inside it.
[0045] Furthermore, as Figure 1 、 Figure 3 and Figure 9 shown, it further includes a steel mesh 7. The steel mesh 7 is arranged inside the concrete foundation 6 and is located on one side of the drain pipe 3. The steel mesh 7 can be used to enhance the structural strength of the hollow-structured concrete foundation 6.
[0046] Furthermore, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, it further includes a connecting flange 8. The connecting flange 8 is arranged at the end of the steel corrugated plate lining 14. A through hole 9 for passing through the drainage conduit 1 is provided on the connecting flange 8. The connecting flanges 8 at the ends of adjacent two steel corrugated plate linings 14 are abutted and locked. The connecting flange 8 close to the concrete foundation 6 is placed on the concrete foundation 6 and locked with the concrete foundation 6. A number of bolt holes are provided on the connecting flange 8. During installation, only need to abut the connecting flanges 8 on adjacent two steel corrugated plate linings 14 arranged along the tunnel width direction together, and then thread the bolts with the bolt holes on the two connecting flanges 8. The structure is simple, the connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort. When the water inlet tank 4 is a long strip-shaped notch running through the length direction of the drainage conduit 1, a water seepage tank 15 is provided at the position on the connecting flange 8 corresponding to the water inlet tank 4 and the through hole 5, which can prevent water from accumulating on the connecting flange 8.
[0047] Further, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 shown, it further includes anchor bolts 10. The connecting flange 8 close to the concrete foundation 6 is locked with the concrete foundation 6 by means of the anchor bolts 10. The number of the anchor bolts 10 is multiple, and all the anchor bolts 10 located on the same concrete foundation 6 are arranged along the length direction of the concrete foundation 6. Fixing the connecting flange 8 on the concrete foundation 6 by using the anchor bolts 10 can ensure the overall stability and safety of the structure.
[0048] Further, as Figure 11 shown, it further includes reinforcing ribs 11. The reinforcing ribs 11 are arranged between the connecting flange 8 and the steel corrugated plate lining 14. The number of the reinforcing ribs 11 is multiple, and they are located on both sides of the through hole 9. By designing the reinforcing ribs 11, the strength of the connecting flange 8 provided with the through hole 9 can be improved.
[0049] Further, as Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10As shown, it further includes a circumferential flange 12 and a side support plate 13. The circumferential flange 12 is provided on both sides of the steel corrugated plate lining 14. The circumferential flanges 12 at the ends of two adjacent steel corrugated plate linings 14 arranged axially along the steel corrugated plate lining 14 are abutted and locked together. The side support plate 13 is arranged on the outer wall of the steel corrugated plate lining 14 and is located inside the circumferential flange 12. A buffer layer filling cavity is formed between the circumferential flange 12 and the side support plate 13. The side support plate 13 is an arc-shaped plate piece. Concrete or polyurethane foaming agent can be poured into the buffer layer filling cavity between the circumferential flange 12 and the side support plate 13 to reduce the impact of the wind pressure generated when the train passes on the arch culvert of the steel corrugated plate lining 14. A number of bolt holes are provided on the circumferential flange 12. During installation, only the circumferential flanges 12 on two adjacent steel corrugated plate linings 14 arranged axially along the steel corrugated plate lining 14 need to be abutted together, and then the bolts are threadedly connected to the bolt holes on the two circumferential flanges 12. The structure is simple, the connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort.
