Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and particularly relates to a diversion and drainage structure in a tunnel of a water conservancy project. Background Technique

[0002] A water conservancy project refers to various projects built to control, regulate and utilize surface water and groundwater in nature in order to achieve the purpose of eliminating disasters and bringing benefits. Water conservancy projects often require the excavation of tunnels, and workers need to work inside the tunnels. Therefore, the drainage structure inside the tunnels must be well designed to facilitate the construction of workers and subsequent use. However, in the existing drainage structure inside the tunnels, generally only a filter plate or a filter screen is set, which can only filter some larger debris and sundries, while the sediment contained in the flowing water cannot be filtered. It cannot filter sundries in multiple categories. Once the flowing water is small and the flow rate is slow, the sediment in the water will precipitate in the drainage trough, and it is easy to cause blockage of the drainage trough after a long time. At the same time, the filter plate or filter screen in the existing drainage structure and the drainage structure are integrated, and it is relatively inconvenient to disassemble and install. For this reason, a diversion and drainage structure in a tunnel of a water conservancy project is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a diversion and drainage structure in a tunnel of a water conservancy project, which has the functions of filtering different impurities and filtering sediment when the flowing water is small, preventing sediment deposition from causing blockage of the drainage trough, and at the same time, the structure inside the drainage trough is also convenient for installation and disassembly, facilitating the cleaning of the filtered sundries, and solving the problems raised in the above background technique.

[0004] The technical solution adopted by the utility model is a diversion and drainage structure in a tunnel of a water conservancy project, which includes a drainage trough, a filtering leaky frame and a cover plate. The filtering leaky frame is detachably installed in the drainage trough. The cover plate is laid on the top surface of the filtering leaky frame and is detachably connected to the drainage trough. A filtering leaky cover is hinged on the cover plate. A sedimentation bin is opened at the bottom of the filtering leaky frame. A filtering cotton layer is installed in the sedimentation bin. A plurality of drainage holes are opened on the bottom surface of the sedimentation bin.

[0005] Further, upper installation grooves are opened on both sides of the top surface of the drainage trough. Both ends of the cover plate can be embedded in the upper installation grooves and are connected to the upper installation grooves through bolts. Reinforcing plates are symmetrically installed at the bottom inside the drainage trough, and the reinforcing plates can interfere with the bottom of the filtering leaky frame.

[0006] Further, a handle is installed on the upper surface of the filtering cotton layer.

[0007] Further, sliding grooves are symmetrically opened on both inner side walls of the drainage trough. Sliders are symmetrically arranged on both sides of the filtering leaky frame, and the sliders can be slidably installed in the sliding grooves.

[0008] Further, a plurality of water-permeable square holes are formed in the four walls of the filtering leakage frame.

[0009] Further, a positioning block is arranged at the bottom of one end of the drainage trough, a positioning groove is formed at the bottom of the other end of the drainage trough, and the positioning blocks and positioning grooves on adjacent drainage troughs can be mutually engaged.

[0010] Further, insertion slots are formed on both sides of one end of the drainage trough, insertion plates are arranged on both sides of the other end of the drainage trough, and the insertion plates and insertion slots on adjacent drainage troughs can be mutually engaged.

[0011] Further, a fixing bin is formed in the insertion plate, a spring is fixedly installed in the fixing bin, limiting beads fixedly connected to the spring are slidably installed at both ends of the fixing bin, and limiting holes adapted to the limiting beads are symmetrically formed on the side wall of the insertion slot.

[0012] Further, a counterweight block is fixedly installed in the drainage trough.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer and more understandable, the technical solution of the utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1-4 As shown, the utility model provides a diversion and drainage structure in a water conservancy project tunnel, comprising a drainage trough 1, a filter drain frame 6 and a cover plate 3, wherein the filter drain frame 6 is detachably installed in the drainage trough 1, the cover plate 3 is laid on the top surface of the filter drain frame 6 and is detachably connected to the drainage trough 1, a filter drain cover 13 is hinged on the cover plate 3, a sedimentation bin 8 is provided at the bottom of the filter drain frame 6, a filter cotton layer 9 is installed in the sedimentation bin 8, and a plurality of drainage holes 10 are provided on the bottom surface of the sedimentation bin 8.

[0025] External water such as rainwater can enter the drain trough 1 through the filter cover 13 on the cover plate 3. At the same time, the filter cover 13 can prevent large and heavy debris from entering. In some examples, a filter net can be set on the bottom surface of the filter cover 13 to filter impurities such as small gravel and leaves.

[0026] The water flow entering the drainage trough 1 will flow into the filter frame 6, and then into the sedimentation bin 8 at the bottom of the filter frame 6. When passing through the filter cotton layer 9, some fine sediment contained in the flowing water can be filtered, and then the flowing water is discharged through the drainage hole 10 at the bottom of the sedimentation bin 8.

[0027] A plurality of water-permeable square holes 12 are provided on the four walls of the filter frame 6. When the water flow is too large, the water that cannot be discharged through the drainage holes 10 at the bottom of the sedimentation bin 8 in time can be discharged through the water-permeable square holes 12 to avoid poor water discharge. When the water flow is large, the silt will also flow away quickly and will not settle in the drainage trough 1.

[0028] On both sides of the top surface of the drainage trough 1, upper installation grooves 2 are provided. Both ends of the cover plate 3 can be embedded in the upper installation grooves 2 and connected to the upper installation grooves 2 by bolts. The upper installation grooves 2 can limit the cover plate 3. At the same time, the bolt connection method also facilitates the installation and disassembly of the cover plate 3; Reinforcing plates 7 are symmetrically installed at the bottom inside the drainage trough 1. The reinforcing plates 7 can interfere with the bottom of the filter leakage frame 6, thereby preventing the filter leakage frame 6 from shifting in the drainage trough 1.

[0029] A handle 11 is installed on the upper surface of the filter cotton layer 9. The handle 11 can facilitate the staff to lift the filter cotton layer 9 and take it out; Sliding grooves 4 are symmetrically provided on both inner side walls of the drainage trough 1. Sliders 5 are symmetrically arranged on both sides of the filter leakage frame 6. The sliders 5 can be slidably installed in the sliding grooves 4. The cooperation between the sliders 5 and the sliding grooves 4 plays a positioning role, facilitating the disassembly and assembly of the filter leakage frame 6.

[0030] In some examples, one end of the filter leakage cover 13 is hinged to the cover plate 3, and a handle is provided at the other end, which is convenient for opening the filter leakage cover 13.

[0031] When it is necessary to clean the filter inside the drainage trough 1, the filter leakage cover 13 can be opened upward, and then the filter screen on the bottom surface of the filter leakage cover 1 can be cleaned. Subsequently, the cover plate 3 is removed, the filter leakage frame 6 is pulled, and the slider 5 slides along the sliding groove 4 to completely remove the filter leakage frame 6. Then, the filter cotton layer 9 is taken out through the handle 11. After that, the impurities filtered in the drainage trough 1 can be cleaned to prevent the drainage trough 1 from being blocked.

[0032] Embodiment 2

[0033] As Figures 1-5 shown, a positioning block 20 is provided at the bottom of one end of the drainage trough 1, and a positioning groove 21 is provided at the bottom of the other end of the drainage trough 1. The positioning block 20 and the positioning groove 21 on adjacent drainage troughs 1 can be mutually engaged. Insertion slots 18 are provided on both sides of one end of the drainage trough 1, and insertion plates 14 are provided on both sides of the other end of the drainage trough 1. The insertion plates 14 and the insertion slots 18 on adjacent drainage troughs 1 can be mutually engaged. As Figure 5 shown, a fixed bin 15 is provided on the insertion plate 14. A spring 16 is fixedly installed in the fixed bin 15. Limit beads 17 fixedly connected to the spring 16 are slidably installed at both ends of the fixed bin 15. Limiting holes 19 adapted to the limit beads 17 are symmetrically provided on the side wall of the insertion slot 18. A counterweight block 22 is fixedly installed inside the drainage trough 1. The counterweight block 22 can increase the stability of the drainage trough 1 and prevent it from shifting.

[0034] When laying the drainage trough 1, an appropriate number of drainage troughs 1 can be selected and assembled according to the length of the pre-excavated trench. The connection method between adjacent drainage troughs 1 is as follows: the positioning block 20 on the drainage trough 1 is made to correspond to the positioning groove 21 on the adjacent drainage trough 1, and the insertion plate 14 is made to correspond to the insertion slot 18 on the adjacent drainage trough 1. Then, the drainage trough 1 is pressed down, so that the positioning block 20 is inserted into the positioning groove 21 and the insertion plate 14 is inserted into the insertion slot 18. During the process of the insertion plate 14 gradually being embedded in the insertion slot 18, the limiting bead 17 is squeezed by the insertion slot 18 and contracts into the fixed bin 15. At this time, the spring 16 is compressed. Until the limiting bead 17 moves to a position corresponding to the limiting hole 19, the spring 16 resumes its deformation and pushes the limiting bead 17 into the limiting hole 19. At this time, the adjacent drainage troughs 1 can be tightly connected. In this way, the drainage troughs 1 can be combined one by one.

[0035] Correspondingly, when it is necessary to disassemble the combined drainage troughs 1, only need to pull up the drainage trough 1, and the limiting bead 17 retracts back into the fixed bin 15 under the extrusion of the limiting hole 19, thereby disassembling the drainage trough 1.

[0036] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
