Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically to a drainage structure for tunnel lining heat tracing that is easy to inspect and replace. Background Technology

[0002] Water seepage in tunnel lining is a common tunnel problem. In existing technologies, drainage pipes are usually buried in grooves in areas prone to water seepage inside the tunnel, and the drainage pipes guide the seepage water into the tunnel drainage system.

[0003] In practice, it has been found that as winter temperatures drop, seepage water in drainage pipes easily freezes and clogs, or even bursts, leading to damage to the tunnel lining. Therefore, installing electric heating tape on the side of the drainage pipe to heat it has become a common solution.

[0004] However, the electric heating cable is buried in the groove of the tunnel wall along with the drainage pipe. After installation, the groove is sealed with concrete. In subsequent maintenance and replacement of the electric heating cable, it is necessary to break the concrete, which is quite inconvenient. Utility Model Content

[0022] The second installation component includes:

[0023] A connecting block, the two first docking blocks and the two arc-shaped plates can surround the drain pipe in the middle, and the connecting block has a horizontal through-groove installation groove.

[0024] The second docking block is provided in two parts. The two second docking blocks are respectively connected to the two ends of the connecting block on the side facing the first docking block. The end of the second docking block away from the connecting block is provided with a docking groove that is adapted to the first docking block and the wedge block.

[0058] See Figures 1 to 8 This embodiment provides a tunnel lining heat tracing cable drainage structure that is easy to inspect and replace. Multiple such drainage cable tracing cables are provided along the length of the drainage pipe 20.

[0059] The tunnel lining heating cable drainage structure includes a first installation component 10, a second installation component 30, two electric heating cables 40, and a baffle 50.

[0060] A groove is made in the inner wall of the tunnel where water is prone to seepage. An arched drainage pipe 20 is installed in the groove. Multiple guide pipes (not shown) are connected to the outside of the drainage pipe 20. Water seeping from the tunnel wall flows into the drainage pipe 20 through the guide pipes. The drainage pipe 20 guides the water into the tunnel drainage system below.

[0061] The first mounting component 10 can be fitted to the outer periphery of the drain pipe 20 (near the bottom of the groove) within the tunnel wall groove, and the second mounting component 30 can be fitted to the inner periphery of the drain pipe 20 (near the opening of the groove) within the tunnel wall groove. Two electric heating cables 40 can be fitted to both sides of the drain pipe 20 (near the two opposite sidewalls of the groove), and the baffle 50 is used to install at the opening of the tunnel wall groove. The second mounting component 30 can be selectively connected to the first mounting component 10 or the baffle 50; the second mounting component 30 can be connected to both the first mounting component 10 and the baffle 50 simultaneously; the second mounting component 30 and the first mounting component 10 can cooperate to fix the two electric heating cables 40 to the drain pipe 20.

[0062] In this embodiment, when inspecting the electric heating cable 40, the baffle 50 is separated from the second mounting component 30, exposing the first mounting component 10, the second mounting component 30, and the electric heating cable 40 in the groove for easy inspection; when replacing the electric heating cable 40, the baffle 50 is connected to the second mounting component 30, and the second mounting component 30 is separated from the first mounting component 10. When the baffle 50 and the second mounting component 30 are removed, the fixation of the second mounting component 30 and the first mounting component 10 on the electric heating cable 40 is released, and the electric heating cable 40 can be directly replaced, which is more convenient.

[0063] In the second embodiment: the first mounting component 10 includes an arc-shaped plate 11 and a first docking block 12.

[0064] Two symmetrically arranged arc-shaped plates 11 extend along the length of the drain pipe 20. The two arc-shaped plates 11 are detachably connected and fit against the outer periphery of the drain pipe 20. Rubber strips or similar materials can be installed on the inner side of the arc-shaped plates 11 to increase friction between them and the drain pipe 20, preventing relative displacement. At least two pairs of first connecting blocks 12 are provided. Each pair of first connecting blocks 12 connects to one opposite end of each of the two arc-shaped plates 11. Each pair of first connecting blocks 12 is located on both sides of the drain pipe 20, forming an installation seam 18 between the first connecting blocks 12 and the drain pipe 20 to accommodate the electric heating tape 40. The first connecting blocks 12 can be detachably connected to the second mounting assembly 30. Flexible insulation material can also be adhered to the inner side of the first connecting blocks 12 to reduce heat loss from the electric heating tape 40.

[0065] In this embodiment, the detachable design of the two arc-shaped plates 11 allows them to be accessed to the outer periphery (bottom of the groove) of the drain pipe 20 in stages. The reduced volume of a single arc-shaped plate 11 makes it easier to insert it from the groove into the outer periphery of the drain pipe 20 during installation. The installation gap 18 formed between the inner side of the first mating block 12 and the outer wall of the drain pipe 20 is slightly smaller than the thickness of the electric heating tape 40. This allows the electric heating tape 40 to be temporarily held by the first mating block 12 and the drain pipe 20 when it is pushed into the installation gap 18, thus facilitating the subsequent docking of the second installation component 30 with the first mating block 12.

[0066] In the third embodiment:

[0067] The end of the arc plate 11 is provided with a first hole 13 along its length direction; the end of the arc plate 11 is also provided with a connecting notch 14 along its length direction. The connecting notches 14 on the two arc plates 11 are opposite to each other, and the connecting notches 14 are connected to the first hole 13. The width of the connecting notch 14 is smaller than the diameter of the first hole 13.

[0068] The first mounting assembly 10 also includes an arc-shaped rod 15 and a connecting plate 16.

[0069] Two arc-shaped rods 15 are provided. One end of each arc-shaped rod 15 can be slidably inserted into the corresponding first hole 13, and the other end of each arc-shaped rod 15 protrudes out of the first hole 13. Both ends of the connecting plate 16 are connected to the two arc-shaped rods 15, and the ends of the connecting plate 16 connected to the arc-shaped rods 15 are located in the corresponding connecting notches 14.

[0070] In this embodiment, the arc-shaped rod 15 and the connecting block 31 can connect the two arc-shaped plates 11 together, and the arc-shaped rod 15 protruding out of the first hole 13 can abut against the arc-shaped block of another tunnel lining heat tracing drainage structure. When the arc-shaped rod 15 of each tunnel lining heat tracing drainage structure abuts against the arc-shaped block of another tunnel lining heat tracing drainage structure, and the two tunnel lining heat tracing drainage structures at both ends are fixed to the tunnel wall or abut against the ground, each tunnel lining heat tracing drainage structure will not have relative displacement with the drainage pipe 20.

[0071] In the fourth embodiment:

[0072] The first mounting component 10 also includes a limiting block 17; multiple pairs of limiting blocks 17 are provided; each pair of limiting blocks 17 is connected to the opposite ends of two arc-shaped plates 11; the limiting blocks 17 can form an mounting seam 18 with the drain pipe 20.

[0073] In this embodiment, the limiting block 17 has one of the functions of the first docking block 12, namely, to restrict the electric heating tape 40 so that the electric heating tape 40 can be kept in contact with the outer wall of the drain pipe 20.

[0074] In the fifth embodiment:

[0075] A wedge block 19 is connected to the outer side of the first docking block 12 away from the corresponding arc plate 11; the side of the wedge block 19 facing away from the first docking block 12 is a guide slope 191. Multiple sets of second mounting components 30 are provided, and each set of second mounting components 30 corresponds to a pair of first docking blocks 12.

[0076] The second mounting component 30 includes a connecting block 31, a second mating block 32, a slider 33, a spring 34, an extension block 35, and a locking block 36.

[0077] The connecting block 31, two first docking blocks 12 and two arc plates 11 can surround the drain pipe 20 in the middle. The connecting block 31 has an installation groove 311 that runs horizontally through it.

[0078] There are two second docking blocks 32. The two second docking blocks 32 are respectively connected to the two ends of the connecting block 31 on the side facing the first docking block 12. The end of the second docking block 32 away from the connecting block 31 is provided with a docking groove 321 that is adapted to the first docking block 12 and the wedge block 19. The width of the docking groove 321 is slightly larger than the sum of the width of the wedge block 19 and the width of the first docking block 12.

[0079] Two sliders 33 are provided, and both sliders 33 are slidably disposed in the mounting groove 311 along the through direction of the mounting groove 311. Specifically, grooves are formed on two opposite side walls of the mounting groove 311, and strip-shaped protrusions are connected to the corresponding grooves on both sides of the sliders 33, and the strip-shaped protrusions slide in cooperation with the grooves.

[0080] Spring 34 is located in mounting groove 311, and its two ends are connected to two sliders 33 respectively. Specifically, holes are opened at the opposite ends of the two sliders 33, and the two ends of spring 34 are connected to the bottom of the holes on the two sliders 33 respectively, so that the two sliders 33 can abut against each other under the action of spring 34.

[0081] Two extension blocks 35 are provided, and the two extension blocks 35 are respectively connected to the ends of the two sliders 33 away from the spring 34. The two extension blocks 35 are located outside the two second docking blocks 32. Two locking blocks 36 are provided symmetrically. The locking blocks 36 are connected to the ends of the corresponding extension blocks 35 away from the sliders 33. The locking blocks 36 are located on the side of the second docking block 32 opposite to the connecting block 31.

[0082] When the first mating block 12 and the wedge block 19 are inserted into the mating groove 321, the locking block 36 passes through the guide slope 191 of the wedge block 19, causing the two sliders 33 to move away from each other. After the locking block 36 passes through the guide slope 191, the plane of the locking block 36 abuts against the plane of the wedge block 19. Specifically, the side of the locking block 36 opposite to the second mating block 32 is a plane, and the side of the locking block 36 opposite to the first mating block 12 is also a plane, and the two planes are perpendicular to each other. The side of the wedge block 19 away from the first mating block 12 is an inclined plane, and the side of the wedge block 19 away from the connecting block 31 is a plane.

[0083] In this embodiment, the two arc-shaped plates 11 are connected and located on the outer periphery of the drain pipe 20. The electric heating tape 40 is laid along the length of the drain pipe 20 and inserted into the installation seam 18 between the connecting block and the drain pipe 20. At this time, the connecting block 31 is brought close to the arc-shaped plate 11. The connecting grooves 321 on the second connecting blocks 32 at both ends of the connecting block 31 align with the first connecting block 12 and the wedge block 19. At this time, the locking block 36 gradually passes through the guide slope 191 on the wedge block 19, and then the plane of the locking block 36 abuts against the plane of the wedge block 19 to achieve locking. Thus, the two arc-shaped plates 11 and the connecting block 31 enclose the drain pipe 20 in the middle. When the first corresponding block is inserted into the connecting groove 321, the second connecting block 32 closes the installation seam 18. At this time, the second connecting block 32, the arc-shaped plate 11, and the drain plate enclose the electric heating tape 40 in the middle, thus fixing the electric heating tape 40. When unlocking is required, the two sliders 33 are pushed away from each other.

[0084] In the sixth embodiment:

[0085] The baffle 50 has a through second hole 51. The second mounting assembly 30 also includes two symmetrically arranged bow-shaped posts 37 and a locking sleeve 38.

[0086] The cross-section of the bow-shaped post 37 is bow-shaped. Two bow-shaped posts 37 are connected to the adjacent ends of two sliders 33, respectively. The two bow-shaped posts 37 can pass through the second hole 51. The cross-section of the bow-shaped post 37 resembles a crescent moon. The arc segments of the cross-sections of the two bow-shaped posts 37 are two segments of a circle. The inner wall of the locking sleeve 38 can be threaded to the outer wall of the two bow-shaped posts 37; the locking sleeve 38 can abut against the side of the baffle 50 opposite to the connecting block 31.

[0087] In this embodiment, after the two arc-shaped posts 37 pass through the second hole 51 of the baffle 50, they are rotated by the locking sleeve 38 and abut against the baffle 50, thus fixing the baffle 50 to the connecting block 31. Multiple protrusions can be provided on the end of the locking sleeve 38 facing the baffle 50, and these protrusions can abut against the baffle 50.

[0088] In the seventh embodiment:

[0089] Each of the two arched pillars 37 has a limiting plate 39 connected to its opposite side. The shape of the second hole 51 is the same as the cross-section of the arched pillars 37 and the limiting plate 39, and the limiting plate 39 can pass through the second hole 51. A handle is connected to the baffle 50. When the arched pillars 37 are far apart, the limiting plate 39 on the two arched pillars 37 can abut against the baffle 50.

[0090] In this embodiment, when the electric heating cable 40 needs to be inspected, the locking sleeve 38 can be unscrewed and the baffle 50 removed. At this time, the connecting block 31 and the locking plate lock the electric heating cable 40 onto the drain pipe 20. The electric heating cable 40 can be checked for malfunction by observing or touching it after powering on to see if it gets hot. When the electric heating cable 40 needs to be replaced, after unscrewing the locking sleeve 38, hold the handle with one hand and use a tool similar to a flathead screwdriver to insert between the two bow-shaped posts 37, thereby causing the two internal sliders 33 to move away from each other and the two limiting plates 39 to move away from each other. At this time, pulling the baffle 50 can remove the connecting block 31, the second docking block 32, etc., and then the electric heating cable 40 can be replaced directly.

In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
