[0002] As an important spatial object in mining, the rationality of the design of the tunnel is the guarantee for safe mining and smooth operation of the mine. During the construction of the tunnel, in order to ensure the normal water use and drainage of the mining area, it is necessary to build a drainage ditch in it. However, when constructing mining tunnels in some high-altitude and cold areas, the drainage ditch is prone to freezing of water under the influence of extremely cold weather, which in turn causes various diseases such as frost heave of surrounding rocks, lining cracking, ice cones at the bottom of the tunnel, ice blockage of ditches, and freezing of lines, which affect safe operation and normal use of buildings.

[0003] To address the above issues, existing mine tunnel drainage ditches mostly use insulation ditches, that is, insulation materials are added to the upper part of the ditch to reduce the heat exchange between the ditch and the outside world to ensure that the ditch does not freeze. However, the problem is that if the water volume in the ditch is small and the flow rate is low, this type of insulation ditch will also freeze in extremely cold conditions; at the same time, in actual use, it is difficult to quickly perform manual auxiliary dredging operations in the ditch.

[0004] Therefore, the utility model proposes a mine tunnel drainage ditch antifreeze system. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The utility model provides a technical solution for the antifreeze system of the drainage ditch in the mine tunnel: it includes a drainage ditch 1, the top of the drainage ditch 1 is fixedly connected with an upper pouring layer 2, the inner side of the upper pouring layer 2 is provided with a disassembly and assembly area 3, the upper pouring layer 2 is laid with a first insulation layer 4, a second insulation layer 5 and a third insulation layer 6, the inner side of the disassembly and assembly area 3 is embedded with a cover plate assembly 7, the cover plate assembly 7 includes a first cover plate 9 and a second cover plate 10 fixedly connected, the bottom end of the first cover plate 9 is fixedly connected with a frame plate 11, the surface of the frame plate 11 is fixedly connected with a supporting leg 12, and the inner side of the disassembly and assembly area 3 is provided with a mounting groove 8.

[0026] like Figure 1-3As shown, the drainage ditch 1 is opened in a trapezoidal shape as a whole, and its bottom opening is larger than the upper opening. The upper casting layer 2 is cast in a rectangular frame layer of cement, and is covered along the top of the drainage ditch 1 as a whole. The inner bottom surface of the upper casting layer 2 is open corresponding to the position of the disassembly and assembly area 3. The disassembly and assembly area 3 is located in the center of the inner side of the upper casting layer 2 and is rectangular and concave. The installation groove 8 is opened horizontally along the inner surface of the disassembly and assembly area 3. Through the trapezoidal drainage ditch 1, the external water flow is guaranteed while having a certain insulation effect. The upper casting layer 2 is used to facilitate the laying of the first insulation layer 4, the second insulation layer 5 and the third insulation layer 6, and at the same time, the basic insulation effect is achieved from the open position above the drainage ditch 1. The disassembly and assembly area 3 is coordinated with the installation groove 8 to facilitate the installation and positioning of the cover assembly 7 on the inner side of the upper casting layer 2.

[0027] The external water source is discharged and processed along the drainage ditch 1. The user installs the cover assembly 7 along the disassembly and assembly area 3 on the inner side of the upper casting layer 2, and then lays the three groups of insulation layers on the inner side of the upper casting layer 2 in sequence, and cooperates with the upper casting layer 2 to ensure the insulation effect of the drainage ditch 1. When manual operation is required on the inside of the drainage ditch 1, the cover assembly 7 can be taken out from the disassembly and assembly area 3 using external tools.

[0028] like Figure 2 As shown, the first insulation layer 4, the second insulation layer 5 and the third insulation layer 6 are laid in sequence from bottom to top on the inner side of the upper casting layer 2. The three are respectively arranged as a hard polyurethane layer, a cinder layer and an asphalt layer, and a geotextile layer is laid between the three. Through the first insulation layer 4, the second insulation layer 5 and the third insulation layer 6, the effect of insulating the drainage ditch 1 from the open position above is achieved.

[0029] like Figure 3-5 As shown, the first cover plate 9 and the second cover plate 10 are both configured as concrete steel cover plates, which are stacked in an upper and lower position, and the end angle positions between the two are connected by a buffer spring, and the frame plate 11 is configured as a metal frame plate, which is vertically arranged in a "Z" shape and fixedly connected to the two sides of the bottom end of the first cover plate 9. Rectangular inner hook grooves are provided on both sides of the second cover plate 10, and the supporting legs 12 are arranged in an "L" shape, which are configured as metal legs. Multiple groups are arranged outward along the inner inclined surface of the frame plate 11. The first cover plate 9 and the second cover plate 10 are used to cover and insulate the open position of the upper casting layer 2 corresponding to the disassembly and assembly area 3. The frame plate 11 and the supporting legs 12 are used to arrange and fix the external electric heating tape. At the same time, the frame plate 11 configured as a metal frame plate facilitates the rapid disassembly and assembly of the entire cover plate assembly 7.

[0030] The user first arranges the external electric heating tape along the frame 11 and fixes it on the inner surface of the frame 11. After fixing, the entire cover assembly 7 is placed along the disassembly and assembly area 3 into the inner side of the upper casting layer 2. At this time, the frame 11 fits the inner wall of the drainage ditch 1, and the entire cover assembly 7 has good stability. During actual use, it can effectively ensure the internal temperature of the drainage ditch 1 and play a heat preservation effect. When manual auxiliary operation is required on the drainage ditch 1, the user uses the external hook rod to hook up the entire cover assembly 7, and then manual operation can be performed on the inside of the drainage ditch 1 from the open position on the inner side of the upper casting layer 2.

[0031] The user can set up a temperature detection mechanism at the position of the support leg 12 to detect the temperature in the drainage ditch 1.

[0032] The working principle of the present invention is as follows: by arranging an upper pouring layer 2 above the drain ditch 1 and laying an insulation layer, the basic insulation operation of the drain ditch 1 is achieved. The external electric heating tape is arranged and fixed by the cover plate assembly 7, thereby ensuring a constant temperature inside the drain ditch 1 and facilitating rapid manual operation inside the drain ditch 1, effectively preventing the water volume and flow rate in the ditch from being small and freezing even in extremely cold conditions.

[0033] When laying the insulation layer, avoid covering the cover plate assembly 7. The user can use a foam insulation layer to cover and insulate the cover plate assembly 7.

[0034] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
