Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, in particular to a tunnel drainage structure for preventing blockage. Background Technique

[0002] The tunnel drainage system is an important facility to ensure the dryness inside the tunnel and prevent water disasters. In the current common design, drainage ditches are opened on both sides of the tunnel, and drainage can be efficiently carried out through the drainage ditches. However, when the existing drainage ditches drain water, a large amount of sediment enters the drainage outlet through the water inlet of the cover plate. After a long time, it is very easy to cause blockage of the drainage outlet. Therefore, there is a particular need to design a tunnel drainage structure for preventing blockage.

[0003] After the applicant's retrieval, the publication number CN219220504U discloses a tunnel drainage structure for preventing blockage. In this solution, a filter screen is installed on the cover plate through an elastic buckle structure, and the sediment passing through the cover plate can be filtered, which has a certain anti-blocking function.

[0004] However, there are certain deficiencies in the above solution. When the above solution is used, since the filter frame has no support structure, it must be installed at the bottom of the cover plate through a buckle structure. Since the tunnel is long and there are many cover plates, even if the disassembly through the buckle is not too troublesome, it will be very time-consuming when the quantity is large, resulting in very time-consuming and inefficient cleaning when the filter frame is removed. At the same time, the horizontal filter screen design is easy to be blocked, resulting in frequent replacement and great inconvenience.

[0005] Therefore, in view of the above problems, it is necessary for the applicant to design a tunnel drainage structure for preventing blockage to solve the problems. Content of the Utility Model

[0006] The utility model provides a tunnel drainage structure for preventing blockage, which solves the problems raised in the above background.

[0007] To solve the above technical problems, a tunnel drainage structure for preventing blockage provided by the utility model includes a tunnel main body. Two drainage channels are arranged on both sides of the road surface inside the tunnel main body. A plurality of alloy plate frames are supported on the supporting surface 1 on both sides inside the drainage channels. The alloy plate frames are spliced with each other. A placement frame is fixed at the bottom of the alloy plate frame. A cover plate and a filter screen plate are placed on the supporting surface 2 inside the alloy plate frame and the placement frame. The middle of the filter screen plate inclines from top to bottom towards both ends, and the two filter screen surfaces of the filter screen plate are designed on the inclined surface. The horizontal parts at both ends of the filter screen plate are placed on the supporting surface 2 of the placement frame.

[0008] Preferably, on the top surfaces of the horizontal portions at both ends of the filter screen plate that are in contact with the inner supporting surface two of the placement frame, there are fixed heightening plates one. On the top surface of the filter screen plate, at the two ends of the inclined surface, there are fixed heightening plates two. The side walls of the heightening plates one and two are adhesively bonded to each other, and the top surfaces of the heightening plates one and two are aligned. Moreover, the outer walls of the heightening plates one and two and the filter screen plate are all in contact with the inner wall of the placement frame.

[0009] Preferably, on the inner walls of the two heightening plates one, there are fixed handles, and the handles are used to take out the filter screen plate from inside the placement frame.

[0010] Preferably, at both ends of the bottom of the cover plate, there are symmetrically fixed water guide plates. The two ends of the water guide plates are of heightened design, and the bottom end of the inclined surface of the water guide plate is close to the middle position of the cover plate.

[0011] Preferably, on both sides of the bottom of the cover plate, there are also symmetrically fixed pressing plates. On the bottom surface of the pressing plates, there are adhesively bonded anti-corrosion rubber blocks, and the anti-corrosion rubber blocks are in contact with and press against the top surface of the heightening plate one.

[0012] Preferably, at both ends of the alloy plate frame, there are respectively fixed insertion blocks and sockets. Adjacent alloy plate frames are fixedly connected by inserting the insertion blocks into the sockets and then adding screws.

[0013] Preferably, at the bottom of the placement frame, there is nailed a preparatory net plate, and the aperture of the mesh surface of the preparatory net plate is the same as that of the filter screen plate.

[0014] Compared with the related art, a kind of anti-blocking tunnel drainage structure provided by the present utility model has the following beneficial effects:

[0015] 1. The present utility model provides a kind of anti-blocking tunnel drainage structure. When installing, the alloy plate frames are sequentially spliced and laid in the drainage channel according to requirements. Then, the filter screen plate is placed into the placement frame and placed on the inner supporting surface two thereof. Finally, the cover plate is placed on the supporting surface two of the alloy plate frame. Then, when draining water, the filtered sediment can accumulate at the bottom end positions of the inclined surfaces on both sides of the filter screen plate. When taking it out for maintenance, directly take out the cover plate, and then take out the filter screen plate for cleaning and replacement. Such a design is very ingenious and easy to operate, and well solves the problems of time-consuming disassembly and assembly and easy blockage in the comparative document.

[0016] 2. The present utility model provides a kind of anti-blocking tunnel drainage structure. In the further optimization of the cover plate, after the cover plate is installed, the pressing plate presses the heightening plate one through the anti-corrosion rubber block to limit the position of the filter screen plate, making the position of the filter screen plate very stable. And when draining water, for the two water guide plates, the bottom ends of the inclined surfaces of the two water guide plates are located on both sides of the highest position in the middle of the filter screen plate. Therefore, the water can be concentrated and drained to the upper end of the inclined surface of the filter screen plate, thereby further improving the filtering efficiency.

[0017] 3. The utility model provides a tunnel drainage structure that prevents blockage. Regarding the further optimization of the filter screen plate, before installing the filter screen plate, bond the heightening plate one and the heightening plate two, and then fix the four plates at the edge of the filter screen plate. Subsequently, after the filter screen plate is taken out during collection, the sediment remains on the filter screen plate due to the limitation of the heightening plate one and the heightening plate two, which facilitates the centralized cleaning by the staff. When installing or taking out, simply hold the handle, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] Depend on Figures 1 - 8 The utility model provides an anti-clogging tunnel drainage structure, including a tunnel body 1, two drainage channels 11 are arranged on both sides of the internal road surface of the tunnel body 1, a plurality of alloy plate frames 2 are supported on the supporting surfaces 12 on both sides inside the drainage channel 11, the alloy plate frames 2 are spliced ​​with each other, a placement frame 25 is fixed to the bottom of the alloy plate frame 2, a cover plate 3 and a filter screen plate 4 are placed on the supporting surface 21 inside the alloy plate frame 2 and the placement frame 25, the middle of the filter screen plate 4 is inclined from top to bottom to both ends, and the two filter screen surfaces of the filter screen plate 4 are designed on the inclined surface, and the horizontal parts at both ends of the filter screen plate 4 are placed on the supporting surface 21 of the placement frame 25.

[0029] Through the above structural design, the specific operation is as follows, by designing the alloy plate frame 2, the placement frame 25 and the filter screen plate 4, the alloy plate frame 2 is spliced ​​in sequence according to the needs during installation, and it is laid on the support surface 12 inside the drain 11, and then it is directly laid on the drain 11 instead of the cover plate 3, and then the filter screen plate 4 is passed through the alloy plate frame 2 and enters the placement frame 25, and then it is placed on the support surface 21 inside it, and finally, the cover plate 3 is placed on the support surface 21 of the alloy plate frame 2. Then, when draining, water enters the placement frame 25 through the holes of the cover plate 3 and passes through the filter screen plate 4 to filter the sediment, and then is discharged from the drain 11. At the same time, the filter screen plate 4 is tilted from the middle to the two ends, so the mesh surface is also tilted, and the filtered sediment can be accumulated at the bottom end of the inclined surface on both sides of the filter screen plate 4 to avoid the horizontal design from being easily blocked. When taking it out for maintenance, the cover plate 3 is directly taken out, and then the filter screen plate 4 is taken out for cleaning and replacement.

[0030] A heightening plate 41 is fixed to the top surface of the horizontal part of the filter screen plate 4 that contacts the inner support surface 21 of the placement frame 25 at both ends, and a heightening plate 2 42 is fixed to the top surface of the filter screen plate 4 at both ends of the inclined surface. The side walls of the heightening plate 41 and the heightening plate 2 42 are bonded to each other, and the top surfaces of the heightening plate 1 41 and the heightening plate 2 42 are aligned, and the heightening plate 1 41 and the heightening plate 2 42 and the outer wall of the filter screen plate 4 are all in contact with the inner wall of the placement frame 25, and the inner walls of the two heightening plates 41 are fixed with handles 43, and the handles 43 are used to take the filter screen plate 4 out of the placement frame 25.

[0031] Through the above structural design, the filter screen plate 4 is further optimized. Before installing the filter screen plate 4, the heightened plate 1 41 and the heightened plate 2 42 are bonded, and then the four plates are fixed at the edge of the filter screen plate 4. Then, after the filter screen plate 4 is collected and taken out, the mud and sand are retained on the filter screen plate 4 due to the limit of the heightened plate 1 41 and the heightened plate 2 42, which makes it convenient for the staff to clean them in a centralized manner. When installing or taking out, just hold the handle 43, which is very convenient.

[0032] Symmetrically fixed at both ends of the bottom of the cover plate 3 are water guide plates 31. Both ends of the water guide plates 31 are designed with increased height, and the bottom end of the inclined surface of the water guide plate 31 is close to the middle position of the cover plate 3. Symmetrically fixed on both sides of the bottom of the cover plate 3 are also pressure plates 32. An anticorrosive rubber block 33 is bonded to the bottom surface of the pressure plate 32, and the anticorrosive rubber block 33 is in contact with and presses against the top surface of the first heightening plate 41.

[0033] Through the above structural design, in the further optimization of the cover plate 3, after the cover plate 3 is installed, the pressure plate 32 presses the first heightening plate 41 through the anticorrosive rubber block 33 to limit the filter screen plate 4. Most of the existing designs of the cover plate 3 are made of metal and have a certain weight. Therefore, the position of the filter screen plate 4 is very stable. When the two water guide plates 31 are draining water, the bottom ends of the inclined surfaces of the two water guide plates 31 are located on both sides of the highest point in the middle of the filter screen plate 4. Therefore, the water can be concentrated and drained to the upper end of the inclined surface of the filter screen plate 4, thereby further improving the filtration efficiency. At the same time, the two ends are designed with increased height to prevent water from flowing out from both sides of the water guide plates 31. It should be noted that in the design, the water falling from the water inlet of the cover plate 3 will fall onto the surface of the water guide plates 31.

[0034] Plug blocks 22 and sockets 23 are respectively fixed at both ends of the alloy plate frame 2. Adjacent alloy plate frames 2 are fixedly connected by inserting the plug block 22 into the socket 23 and then adding screws.

[0035] Through the above structural design, in the splicing optimization, screw holes are provided on the surface of the alloy plate frame 2 at the position of the socket 23, and screw holes are provided on the top surface of the plug block 22. Then, when splicing, the plug block 22 is inserted into the socket 23, and fixation can be achieved by cooperating with screws. In this way, splicing of the required length can be carried out according to the drainage channels 11 of different lengths, improving the applicability. It should be noted that for the outermost alloy plate frame 2, there can be only a plug block 22 or only a socket 23 to prevent water from entering the screw holes.

[0036] A preparatory mesh plate 24 is nailed to the bottom of the placement frame 25. The aperture of the mesh surface of the preparatory mesh plate 24 is the same as that of the filter mesh plate 4.

[0037] Through the above structural design, when in use, a preparatory mesh plate 24 can be additionally installed at the bottom of the placement frame 25. When the filter mesh plate 4 on a certain placement frame 25 is damaged and needs to be replaced, it may take a certain amount of procurement time, such as waiting for one or two days. At this time, the preparatory mesh plate 24 can play a temporary protection role to prevent rain during this period. Since the preparatory mesh plate 24 is not the main filtering mechanism and does not need to be frequently cleaned, it can be connected by screws.

[0038] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
