[0003] However, there are some problems with the current blind boxes on the tunnel drainage blind ditch during drainage: since there are earth slopes near the outside of the tunnel, when it rains heavily, the rain will wash away the soil on the earth slopes, and the soil will flow into the drainage blind ditch with the water. When it rains continuously, the amount of soil entering the drainage blind ditch may increase. At this time, when the water flows through the blind box, the soil may block the filter holes, causing the blind box to be unable to purify the water and discharge it through the filter holes. In this regard, a tunnel three-way blind box self-purification drainage device and method are proposed. Summary of the invention

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1-3The present embodiment provides a tunnel three-way blind box self-purification drainage device, including a three-way blind box 2, filter holes and an anti-blocking mechanism 3 respectively arranged on the three-way blind box 2, the anti-blocking mechanism 3 is used to prevent sludge from blocking the filter holes on the three-way blind box 2, and the water in the tunnel drainage blind ditch 1 is automatically discharged after being filtered through the filter holes. The anti-blocking mechanism 3 includes a water wheel rotating part 31, a crank part 32, a connecting part 33 and a sliding part 34, the two ends of the crank part 32 are respectively connected to the water wheel rotating part 31 and one end of the connecting part 33, one end of the sliding part 34 is sleeved on the other end of the connecting part 33, and the other end of the sliding part 34 slides through the filter hole, and the tunnel drainage The water in the blind ditch 1 drives the water wheel rotating part 31 to rotate, and the water wheel rotating part 31 drives the crank part 32 to rotate. The crank part 32 drives the sliding part 34 to move back and forth along the filter hole through the connecting part 33, so that the mud in the filter hole is separated. The sliding part 34 here will not touch the water wheel rotating part 31 when sliding back and forth. This anti-blocking mechanism 3 does not require an external drive component. The faster the water flow speed, the easier the filter hole is to be blocked. The faster the water flow, the faster the water wheel rotating part 31 rotates, which makes the sliding part 34 move faster. Therefore, the anti-blocking mechanism 3 here can be coordinated with the three-way blind box 2 according to the water flow situation in the tunnel drainage blind ditch 1.

[0032] At present, in order to eliminate water seepage in the tunnel during tunnel construction, it is necessary to set up drainage blind ditches on both sides of the tunnel to drain the seepage water in the tunnel to the outside of the tunnel. When laying templates (blind boxes) for the reserved drainage blind ditches, multiple templates are usually spliced ​​and fixed together by bolts or snap connections, and filter holes are provided on the templates, so that the water in the drainage blind ditch can be automatically purified and discharged when passing through the templates (blind boxes). However, there are some problems with the blind boxes on the current tunnel drainage blind ditches during drainage. Since there are earth slopes near the outside of the tunnel, when it rains heavily, the rainwater will wash away the soil on the earth slope, and the soil will enter the drainage blind ditch with the water flow. When it rains continuously, the soil entering the drainage blind ditch may also increase. At this time, when the water flows through the blind box, the soil may block the filter holes, resulting in the blind box being unable to purify the water and discharge it through the filter holes.

[0033] In order to solve the above problems, in the present embodiment, a support rod 4 is arranged below the filter hole of the three-way blind box 2, a water wheel rotating part 31 is arranged in the internal cavity of the three-way blind box 2, and a crank part 32 is arranged on the support rod 4. The crank part 32 rotatably passes through the support rod 4 and the three-way blind box 2, and the crank part 32 is connected to the water wheel rotating part 31. A sliding part 34 is also arranged on the support rod 4, so that the sliding part 34 slides through the support rod 4 and the filter hole, and the sliding part 34 is connected to the crank part 32 through a connecting part 33. The water in the tunnel drainage blind ditch 1 drives the water wheel rotating part 31 to rotate, and the water wheel rotating part 31 drives the crank part 32 to rotate. The crank part 32 drives the sliding part 34 to move back and forth along the filter hole through the connecting part 33, so that the mud in the filter hole is separated, thereby solving the problem that the mud may block the filter hole when the water flows through the blind box, resulting in the blind box being unable to discharge the purified water through the filter hole.

[0034] Since the water wheel rotating part 31 is moved by the impact of water flow, but the water in the tunnel drainage blind ditch 1 is generally turbid, accompanied by mud or weeds and other debris, the water wheel rotating part 31 may be stuck by debris during movement and cannot rotate. In order to solve this problem, in one embodiment, the water wheel rotating part 31 includes a rotating wheel 311 and a water diversion groove 312 arranged on the outer side of the rotating wheel 311. The center of the rotating wheel 311 is connected to the crank part 32 through a bearing. The water diversion groove 312 is composed of two tangent hemispheres, and the outer side of the water diversion groove 312 is a pointed structure. For this rotating wheel 311, the rotation of the rotating wheel 311 is caused by the impact of water flow. In order to reduce the resistance of the rotating wheel 311 when rotating, the center of the rotating wheel 311 is connected to the crank part 32 through a bearing, and the rotation resistance is reduced by the bearing. In addition, since the rotating wheel 311 and the bearing are both located in the tunnel drainage blind ditch 1, in order to avoid water flow entering between the rotating wheel 311 and the bearing, causing the bearing to rust and affect its rotation, the rotating wheel 311 and the bearing here are connected. The rotating wheel 311 is provided with a plurality of oil holes, and a micro box for containing lubricating oil is also installed on the rotating wheel 311. When the rotating wheel 311 rotates, the lubricating oil in the micro box for containing lubricating oil will flow out from the oil hole and flow into the gap between the rotating wheel 311 and the bearing, so as to ensure that the rotating wheel 311 and the bearing will not rust in the tunnel drainage blind ditch 1, and can always keep rotating well, and can better purify the drainage. At the same time, the water groove 312 outside the rotating wheel 311 is opposite to the water flow direction, which can ensure that the water flow When passing through, it first enters the water channel 312, and the water channel 312 is composed of two tangent hemispheres, and the outer side of the water channel 312 is a pointed structure. The purpose of this design is to facilitate the flow of water through the two tangent hemispheres to better drive the rotating wheel 311 to rotate. The outer side of the water channel 312 is a pointed structure, and the dirt, weeds and other debris in the water flow can be cut through this pointed structure, and then the debris is allowed to flow away with the water to avoid clogging the filter hole or causing the rotating wheel 311 to be stuck and unable to rotate.

[0035] As water flows in the tunnel drainage blind ditch 1, it is filtered and discharged through the filter holes on the three-way blind box 2. In order to better enable the three-way blind box 2 to purify the water in the tunnel drainage blind ditch 1, in one embodiment, the thickness of the rotating wheel 311 is greater than half of the thickness of the tunnel drainage blind ditch 1. There are two purposes for making the thickness of the rotating wheel 311 greater than half of the thickness of the tunnel drainage blind ditch 1. One is to cut and process impurities in the water in the tunnel drainage blind ditch 1 through the rotating wheel 311, and the other is to increase the contact area between the rotating wheel 311 and the water flow, so that the impact energy of the water can be used more to drive the rotating wheel 311 to rotate faster.

[0036] In addition, when the tunnel drainage blind ditch 1 is draining, when the water flow is too fast, the rotating wheel 311 also rotates very fast, and the sliding part 34 also moves very fast at this time. Since the filter hole is small, the sliding part 34 can easily touch the outer edge of the filter hole when moving. Once it touches the outer edge, it is easy to cause the three-way blind box 2 to loosen. In order to solve this problem, in one embodiment, the sliding part 34 is a sliding rod, and the diameter of the sliding rod is half of the diameter of the filter hole. Here, the diameter of the sliding rod is designed to be half of the diameter of the filter hole, so as to leave a certain gap between the sliding rod and the filter hole, avoiding the sliding part 34 from easily touching the outer edge of the filter hole when moving. Once it touches the outer edge, it is easy to cause the three-way blind box 2 to loosen. At the same time, when the filter hole is blocked by soil, it only needs to be poked in the middle part of the filter hole, and the filter hole can be unblocked under the impact of the water flow. Therefore, this design is still designed according to the actual situation of drainage of the tunnel drainage blind ditch 1.

[0037] Further, the crank portion 32 here needs to satisfy the requirement that as the rotating wheel 311 rotates, it can also drive the sliding portion 34 to slide back and forth. In this regard, in one embodiment, the crank portion 32 includes a first connecting rod 321 and a second connecting rod 322, one end of the first connecting rod 321 is connected to one end of the second connecting rod 322, and the angle between the first connecting rod 321 and the second connecting rod 322 is an obtuse angle, one end of the connecting portion 33 is sleeved on the other end of the first connecting rod 321, and the other end of the second connecting rod 322 is connected to the rotating wheel 311, the sliding portion 34 and the other end of the second connecting rod 322 are connected through the same connecting plate 5, and the connecting portion 33 and the sliding portion 34 are vertically arranged, and the connecting plate 5 is arranged on the three-way blind box 2, when the rotating wheel 311 rotates, it drives the second connecting rod 322 to rotate, and the second connecting rod 32 2 drives the first connecting rod 321 to rotate, and the first connecting rod 321 drives the sliding part 34 to move back and forth along the filter hole through the connecting part 33, thereby preventing the filter hole from being blocked by mud. At the same time, one end of the connecting part 33 slides back and forth on the first connecting rod 321, and the one end of the sliding part 34 sleeved on the connecting part 33 slides back and forth relative to the connecting part 33, but in fact the sliding part 34 only moves in the direction perpendicular to the filter hole. In addition, in order to prevent the connecting part 33 from interfering with the sliding part 34 and the first connecting rod 321, the connecting part 33 is vertically arranged with the sliding part 34, and the connecting plate 5 is arranged on the three-way blind box 2. At the same time, it is also necessary to meet the requirement that the sliding part 34 and the other end of the second connecting rod 322 are connected by the same connecting plate 5, and this connecting plate 5 is connected to the three-way blind box 2 through the support rod 4 mentioned above.

[0038] The tunnel three-way blind box self-purification drainage method comprises the following steps:

[0039] S1: First, the tunnel drainage blind ditch 1 is constructed according to the direction of the water flow. The construction here requires that the bottom of the tunnel drainage blind ditch 1 be designed into a slope shape according to the direction of the water flow, so as to not only facilitate the flow of water, but also better allow the water flow to impact the rotating wheel 311;

[0040] S2: Determine the number of three-way blind boxes 2 required according to the length of the tunnel drainage blind ditch 1, then first install the rotating wheel 311 on the three-way blind box 2, and at the same time, face the water channel 312 outside the rotating wheel 311 to the water flow direction, and finally install the tunnel three-way blind box 2 on the tunnel drainage blind ditch 1;

[0041] S3: connecting adjacent three-way blind boxes 2 to each other so that all three-way blind boxes 2 and the tunnel drainage blind ditch 1 form a whole;

[0042] S4: A filter hole is provided in the upper half of the three-way blind box 2, and sliding parts 34 are installed at the filter holes on the surface of the three-way blind box 2 perpendicular to the ground, and all the sliding parts 34 on the same three-way blind box 2 are connected as a whole. In addition, the design of the crank part 32 and the connecting part 33 does not affect the cooperation between the multiple sliding parts 34 and the filter holes. For the convenience of observation, only one sliding part 34 is drawn in the figure. In fact, each filter hole on the surface perpendicular to the ground has a sliding part 34, and the top surface of the three-way blind box 2 does not need to be designed with a sliding part 34, because the hole above is not easy to be blocked. Even if it is blocked, it is easy to automatically dredge under the action of soil gravity and water flow impact;

[0043] S5: Install a support member on the three-way blind box 2 without a filter hole, install a crank part 32 and a sliding part 34 on the support member, connect the sliding part 34 and the crank part 32 through the connecting part 33, and connect the crank part 32 to the axis of the rotating wheel 311, so as to automatically purify the water flow in the tunnel drainage blind ditch 1 through the three-way blind box 2.

[0044] Furthermore, in order to ensure that the self-purification drainage device of the tunnel three-way blind box 2 has a good drainage effect, it is necessary to regularly clean the impurities in the tunnel three-way blind box 2. However, in the prior art, adjacent three-way blind boxes 2 are mostly fixed by bolts. However, due to the presence of water, the bolts are prone to rust and loosen after long-term use, or are inconvenient to remove. In this regard, in one embodiment, the adjacent three-way blind boxes 2 in step S2 are connected by plug-in, and a protrusion is provided at one end of the three-way blind box 2 and a slot is provided at the other end, so that the protrusions of two adjacent three-way blind boxes 2 are plug-in connected with the slots. In addition, in step S2, the three-way blind box 2 and the tunnel drainage blind ditch 1 are interferingly fit, so that the three-way blind box 2 is stuck on the tunnel drainage blind ditch 1. The interference fit is not only convenient for installation and disassembly, but also under the impact of water flow in the tunnel drainage blind ditch 1, the three-way blind box 2 and the tunnel drainage blind ditch 1 will be fixed more firmly.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
