Description

Technical Field

[0001] The utility model relates to the technical field of tunnel drainage, and particularly relates to a treatment device for tunnel gushing water. Background Technique

[0002] Tunnel gushing water, also known as mud and water gushing or water gushing, is a sudden large amount of water gushing phenomenon that occurs during the construction of underground chambers and roadways, especially when passing through areas with developed karst caves, encountering underground river systems, thick layers of cement-containing sand and gravel, and large fracture zones connected to surface water. This phenomenon is extremely harmful to the construction of underground projects such as mines and tunnels. Therefore, it is necessary to reasonably discharge the gushing water through drain pipes.

[0003] After the applicant's retrieval, it is found that in order to save water sources and avoid water resource waste, in existing projects, water distribution pipes are designed on the drain pipes to collect this gushing water and make reasonable use of it. However, these underground waters contain harmful substances such as sediment and bacteria, and it is necessary to perform pretreatment before collection, such as some filtration and adsorption, disinfection and sterilization, etc. For example, a tunnel gushing water treatment device disclosed in Patent No. CN215026686U, the water distribution pipe can divert some of the gushing water into the water tank for collection, and is pretreated through a filtration structure provided in the water distribution pipe, such as permeable bricks, filter plates, and disinfection balls.

[0004] However, through research, it is found that the above-mentioned scheme has certain deficiencies. Since the filtering elements are directly designed in the distribution of the water distribution pipe, and in the traditional design, most of the water distribution pipes are integrally designed with the drain pipe, and in this scheme, the filter plate is still fixed with cement, which belongs to a non-detachable connection. And the sediment content in the underground water is very large, which is extremely easy to cause the clogging of the filtering elements. Therefore, it is necessary to frequently replace the filtering elements for cleaning, but the disassembly is inconvenient, and it is very easy to cause the filtering elements to be clogged and unable to discharge water. Therefore, in view of the above problems, it is necessary for the applicant to design a treatment device for tunnel gushing water to solve the problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a treatment device for tunnel gushing water to solve the problems mentioned in the above background technique.

[0010] Preferably, six hanging rings are connected to the outer wall of the rubber ring through elastic cloth, and the hanging rings are hung on the hooks fixed at the bottom of the annular support plate.

Specific embodiments

[0027] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0028] As Figures 1 - 8 shown, a treatment device for tunnel water inrush provided by the present utility model includes a drain pipe 1. A water distribution pipe 11 is installed at the bottom of the drain pipe 1. A water guide cylinder 12 is fixed at the bottom of the water distribution pipe 11. A filter cylinder 2 is threadedly connected to the bottom of the water guide cylinder 12. A water outlet pipe 21 is installed at the bottom of the filter cylinder 2. An annular support plate 3 is fixed to the inner wall of the filter cylinder 2. A rubber ring 4 is movably connected to the bottom of the annular support plate 3. A nylon mesh 41 for placing sterilizing balls is connected to the inner side of the rubber ring 4. A first ring plate 5 is placed on the top of the annular support plate 3. Two layers of high-efficiency filter screens 51 are fixed to the inner side of the first ring plate 5, and a second ring plate 6 is placed on the top. The top of the second ring plate 6 is in contact with the bottom surface of the water guide cylinder 12 and a coarse-effect filter screen 61 is installed.

[0029] The specific operation is as follows. When recycling and reusing the inrush water, the rubber ring 4 is movably connected to the bottom of the annular support plate 3 inside the filter cylinder 2. At this time, the sterilizing balls can be put into the nylon mesh 41. Then, the first ring plate 5 and the second ring plate 6 are placed on the top of the annular support plate 3 in sequence. After that, the filter cylinder 2 is rotationally connected to the bottom of the water guide cylinder 12 through threading, and the installation method is that the internal thread of the water guide cylinder 12 is docked with the external thread of the filter cylinder 2. After installation, the bottom of the water guide cylinder 12 just presses the second ring plate 6, and the second ring plate 6 presses the first ring plate 5 to complete the fixation. At this time, the nylon mesh 41, the coarse-effect filter screen 61 and the high-efficiency filter screen 51 form a filter element. Then, when guiding water, the water outlet pipe 21 is docked with a mobile water tank, the valve of the water distribution pipe 11 is opened, and water can enter the water guide cylinder 12 and the filter cylinder 2. Different sizes of particulate impurities are filtered through the coarse-effect filter screen 61 and the high-efficiency filter screen 51 on the inner sides of the second ring plate 6 and the first ring plate 5. Then, the water is disinfected by the sterilizing balls in the nylon mesh 41, and finally enters the water tank through the water outlet pipe 21 for collection by the water outlet pipe 21. After the collection is completed, the valve of the water distribution pipe 11 is closed. When it is necessary to clean and maintain the filter element, the filter cylinder 2 is removed, and then the second ring plate 6, the first ring plate 5 and the rubber ring 4 are removed to clean the filter element.

[0030] The coarse-effect filter screen 61 is designed in a conical shape in appearance, and quartz sand particles are filled between the two layers of high-efficiency filter screens 51 to form a sandwich.

[0031] With the above structural design, for further optimization of the filtration effect, since the coarse filter screen 61 needs to filter the largest amount and filter large particles such as stones, the conical design makes its area larger, and the large particle impurities can move down along the inclined plane and accumulate at the bottom, which can effectively avoid blockage and is convenient for collection. The two high-efficiency filter screens 51 can filter small particle impurities, and quartz sand particles are filled between them. The quartz sand particles can adsorb impurities such as suspended substances, colloids, and sediment in the water, which can further enhance the filtration effect on fine particles. It should be noted that in this case, the shape, appearance, and size of the quartz sand particles and the sterilizing balls are not limited, so no relevant description is made in the attached drawings.

[0032] A circular elastic rubber ring 62 is adhesively bonded to the top surface of the second ring plate 6. The elastic rubber ring 62 is in close fit with the water guide cylinder 12, and the outer wall of the elastic rubber ring 62 is aligned with the outer wall of the second ring plate 6. Six inserting rods 63 are uniformly fixed to the bottom of the second ring plate 6. The inserting rods 63 pass through the through holes of the first ring plate 5 and are inserted into the corresponding round holes at the top of the annular support plate 3. The inner and outer diameters of the second ring plate 6, the first ring plate 5, and the annular support plate 3 are the same.

[0033] With the above structural design, for optimization of the installation stability, the elastic rubber ring 62 enhances the sealing performance, avoids water leakage from the joint between the second ring plate 6 and the water guide cylinder 12, and avoids direct contact between the two. At the same time, when assembling, the six inserting rods 63 at the bottom of the second ring plate 6 pass through the first ring plate 5 and are inserted into the round holes at the top of the annular support plate 3, making the coarse filter screen 61 and the high-efficiency filter screen 51 more stable in the horizontal position and not rotating, effectively ensuring the stability during filtration.

[0034] Six hanging rings 42 are connected to the outer wall of the rubber ring 4 through elastic cloth. The hanging rings 42 are hung on the hooks 43 fixed to the bottom of the annular support plate 3.

[0035] By designing the hooks 43 and the hanging rings 42, when installing the rubber ring 4 and the nylon net 41, move the rubber ring 4 to the bottom of the annular support plate 3, and hang each hanging ring 42 on the hook 43 to complete the installation. Such installation is very firm, convenient, and easy to disassemble, which is very practical. It should be noted that the rubber ring 4 has a certain deformation ability and can pass through the ring opening of the annular support plate 3 through a slight bending deformation.

[0036] An inlet pipe 13 is installed at the top of the water guide cylinder 12. The top of the inlet pipe 13 is butted against the bottom of the sub-water pipe 11, and two flanges 7 that are in mutual fit are fixed to the outer walls of the inlet pipe 13 and the sub-water pipe 11. The two flanges 7 are fixedly connected by bolts.

[0037] By designing the flange 7, the water inlet pipe 13 of the water guide cylinder 12 is docked with the water distribution pipe 11 through the flange 7, thus making the water guide cylinder 12 very stable. At the same time, the water guide cylinder 12 needs to be disassembled and maintained after long-term use. Therefore, it can be disassembled by removing the bolts of the contact flange 7.

[0038] Four water pipe joints 22 are evenly installed on the outer wall of the water outlet pipe 21, and valves are provided on each of the water pipe joints 22.

[0039] By designing four water pipe joints 22, when the water outlet pipe 21 is docked with the water tank, the water pipe joints 22 can be docked with the water tank joints through hoses. When receiving water, the valves of the docked water pipe joints 22 are opened, and the water flow is adjusted through the valve on the drain pipe 1. Then, up to four water tanks can be filled with water simultaneously, effectively improving the water filling efficiency. It should be noted that the designs of the relevant valves of the water distribution pipe 11 and the drain pipe 1 are existing design means, and the comparison documents have been published. Therefore, their details and positions will not be elaborated here.

[0040] Enlightened by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
