Description

Technical Field

[0001] This utility model relates to a diversion device for ditch construction. Background Technology

[0002] In fields such as farmland irrigation and municipal engineering, it is common for masonry ditches to experience localized damage, leakage, or collapse due to long-term use, natural aging, or external forces. Repairing such damaged areas usually requires creating a dry, waterless working environment (especially in the construction of ditches that need to be cast in concrete).

[0003] Currently, there are two main traditional construction methods:

[0004] Complete flow interruption and drainage method: This method involves completely cutting off the upstream water flow and emptying the entire canal section. It requires a large construction area and a long construction period, necessitating the interruption of the entire canal's water transport function. This severely impacts agricultural irrigation, ecological water replenishment, and domestic water use in downstream areas, resulting in significant water waste.

[0005] Simple cofferdam method: A temporary cofferdam is built before and after the breach using sandbags or earth and rocks. The water inside the cofferdam is then pumped out before construction can proceed. Although this method reduces the area of ​​flow interruption, it has significant drawbacks: First, the cofferdam has poor sealing, resulting in severe seepage and making the construction area muddy, affecting construction quality and efficiency; second, the installation and dismantling of the cofferdam is time-consuming and labor-intensive, and it disturbs and damages the channel bottom and slopes; finally, this method only intercepts the water and does not solve the problem of water transport. Water from upstream cannot be discharged smoothly, which may still cause problems such as high water levels and overflow.

[0006] Therefore, there is an urgent need in this field for a device that can quickly create a dry and stable waterless work area during local maintenance and construction of ditches, while ensuring that the water flow in the ditch is not interrupted and can be transported normally. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a diversion device for ditch construction that can quickly form a dry and stable waterless working area during local maintenance and construction of ditches, while ensuring that the water flow in the ditch is not interrupted and can be transported normally.

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A diversion device for ditch construction includes:

[0010] Two sealing devices are installed at intervals in the ditch to form a waterless construction area;

[0011] A connecting pipe, which connects the two sealing devices, is used to guide water away from the waterless construction area;

[0012] A drain valve is installed at the connecting pipe to discharge water transported through the connecting pipe into the farmland.

[0013] Preferably, the sealing device includes a frame, an intercepting plate, a drain pipe, a bend pipe, and an anchor bolt. The frame is installed in the ditch and blocks the ditch. A side support rod is fixedly installed on the outside of the frame. The anchor bolt passes downward through the side support rod and is inserted into the soil. A through hole is provided on the side of the frame, through which a filter pipe is inserted. The surface of the filter pipe is evenly distributed with filter holes. A concave hole coaxial with the through hole is provided on the inner wall of the frame. One end of the filter pipe is inserted into the concave hole and fixed, while the other end is located outside the frame. The drain pipe is fixed to the filter pipe, and the other end of the drain pipe passes through the soil and extends into the farmland. The bend pipe is fixed to the end of the drain pipe away from the filter pipe. The connecting pipe connects to the bend pipe. A slot is provided at the top of the frame. The intercepting plate is inserted through the slot and blocks the frame. A sealing plate is fixed to the end of the frame away from the intercepting plate. The filter pipe is located between the intercepting plate and the sealing plate. A filter screen is fixed at the intercepting plate. The filter screen has a filter hole size larger than the filter hole size on the surface of the filter pipe.

[0014] Preferably, a groove is machined on the outside of the frame, and a seal is fixed in the groove, the seal forming a seal between the frame and the trench.

[0015] Preferably, the sealing element includes a hollow air column and an air nozzle. The hollow air column is fixed in the groove, and the air nozzle is connected to the hollow air column. Air is injected into the hollow air column through the air nozzle, so that the hollow air column expands and seals between the frame and the trench.

[0016] Preferably, it also includes a cleaning device for cleaning the surface of the filter tube.

[0017] Preferably, the cleaning device includes a ring, a connecting rod, and a lever, the connecting rod being fixed to the outside of the ring, and the lever being fixed to the top of the connecting rod; a groove is machined on the top of the frame, the connecting rod fitting into the groove, the lever being positioned at the top of the frame, and the filter tube passing through the axis of the ring; bristles are embedded in the inner wall of the ring, and the bristles act on the surface of the filter tube.

[0018] The beneficial effects of this utility model are:

[0019] 1. Achieves true "local uninterrupted flow construction": This invention uses two sealing units to separate a waterless construction area before and after the damage point, while simultaneously diverting upstream water safely downstream through connecting pipes, completely avoiding any impact on the overall water conveyance function of the ditch during construction. Downstream users can resume normal water use without waiting for construction to complete, greatly reducing the socio-economic losses caused by construction.

[0020] 2. Creates a high-quality waterless working environment: The sealing unit, which combines a rigid frame with inflatable seals (such as hollow air columns), has a sealing effect far superior to traditional sandbag cofferdams. It can effectively prevent water seepage, ensure that the construction area is dry and solid, and provide an ideal working surface for maintenance processes such as concrete pouring and bricklaying, significantly improving construction efficiency and repair quality.

[0021] 3. Effective utilization of water resources: This device does not simply drain the water from upstream, but through a controllable water discharge valve, it can guide the water flow in an orderly manner to the farmland that needs irrigation, thus achieving precise delivery of water resources during construction.

[0022] 4. Equipped with cleaning function and high stability: The innovative filter tube design combined with the operable cleaning device can effectively prevent impurities from clogging the flow channel, ensuring the long-term, stable and efficient operation of the flow system, and is especially suitable for ditch environments with a lot of silt.

[0023] 5. Quick installation and reusable: The device adopts a modular design with a clear structure. It is fixed with anchor bolts, making installation and disassembly simple and quick. Attached Figure Description

[0037] See Figure 1 The illustrated diversion device for ditch construction includes:

[0038] Two sealing devices 1 are installed at intervals in the ditch 5 to form a waterless construction area 6;

[0039] Connecting pipe 2, which is connected between the two sealing devices 1, is used to guide water away from the waterless construction area 6; in this embodiment, connecting pipe 2 is a flexible hose.

[0040] A drain valve 3 is installed at the connecting pipe 2, and drains water transported through the connecting pipe 2 into the farmland through the drain valve 3. The opening degree of the drain valve 3 is adjustable, so as to adjust the water flow rate of the drain valve 3 according to the irrigation needs of the farmland.

[0041] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing device 1 includes a frame 11, an intercepting plate 12, a drain pipe 13, a bend pipe 14, and an anchor rod 15. The frame 11 is installed in the ditch and blocks the ditch. A side support rod 16 is fixedly installed on the outside of the frame 11. The side support rod 16 is fixed to the frame 11 by welding. The anchor rod 15 passes downward through the side support rod 16 and is inserted into the soil layer. A through hole 17 is provided on the side of the frame 11. A filter pipe 18 is inserted through the through hole 17. The filter pipe 18 and the through hole 17 are transitionally fitted. The surface of the filter pipe 18 is evenly distributed with filter holes. The size of the filter holes is 2mm~4mm. The inner wall of the frame 11 is provided with a recessed hole 19 coaxial with the through hole 17. In this embodiment, the recessed hole 19 is a threaded hole. One end of the filter tube 18 is inserted into the recessed hole 19 and then threadedly connected and fixed. The other end is located outside the frame 11. The outlet tube 13 is fixed to the filter tube 18 by a threaded connection. The other end of the outlet tube 13 passes through the soil layer and extends into the farmland. The bent tube 14 is fixed to the end of the outlet tube 13 away from the filter tube 18. The bent tube 14 and the outlet tube 13 are fixed by insertion, and the insertion position is sealed with glue. The connecting tube 2 connects to the bent tube 14. The connecting tube 2 is a flexible tube, and it is fixed to the bent tube 14 by a clamp. A slot 110 is provided at the top of the frame 11. The interceptor plate 12 is inserted through the slot 110 and blocks the frame 11. A sealing plate 111 is fixed at the end of the frame 11 away from the interceptor plate 12. The filter tube 18 is located between the interceptor plate 12 and the sealing plate 111. A filter screen 113 is fixed at the interceptor plate 12. The filter pore size of the filter screen 113 is 6mm~10mm. The filter pore size of the filter screen 113 is larger than the filter pore size on the surface of the filter tube 18.

[0042] See Figure 2 and Figure 4 As shown, a groove 114 is machined on the outside of the frame 11, and a sealing element is fixed in the groove 114, which forms a seal between the frame 11 and the groove.

[0043] See Figure 6As shown, the sealing element includes a hollow air column 115 and an air nozzle 116. The hollow air column 115 is fixed in the groove 114, and the air nozzle 116 is connected to the hollow air column 115. Air is injected into the hollow air column 115 through the air nozzle 116, so that the hollow air column 115 expands and seals between the frame 11 and the trench.

[0044] In the above technical solution, the use of air column 115 expansion can further improve the sealing between frame 11 and ditch, ensuring that there is no obvious water seepage in the construction area.

[0045] See Figure 3 and Figure 7 As shown, it also includes a cleaning device 4, which cleans the surface of the filter tube 18.

[0046] See Figure 3 , Figure 4 and Figure 7 As shown, the cleaning device 4 includes a ring 41, a connecting rod 42, and a lever 43. The connecting rod 42 is fixed to the outside of the ring 41, and the lever 43 is fixed to the top of the connecting rod 42. A groove 121 is machined on the top of the frame 11, and the connecting rod 42 is fitted into the groove 121. The lever 43 is limited to the top of the frame 11. The filter tube 18 passes through the axis of the ring 41. Brush bristles 44 are implanted in the inner wall of the ring 41. The brush bristles 44 are nylon bristles and are fixed to the ring 41 by gluing. Correspondingly, an implantation hole for implanting the brush bristles needs to be provided in the inner wall of the ring 41. The brush bristles 44 act on the surface of the filter tube 18.

[0047] Considering that the filter tube has a smaller pore size, the chance of it being clogged will increase. Therefore, we designed the cleaning device 4 mentioned above. The surface of the filter tube can be swept and cleaned by the sliding of the cleaning device 4.

[0048] Correspondingly, a cleaning hole 123 is also provided at the top of the frame 11 for cleaning the blockages removed by the brush.

[0049] The working process of this device is as follows:

[0050] During construction, a sealing unit 1 is first installed upstream and downstream of the ditch, according to the length of the construction section. During installation, a trench for pre-embedded outlet pipes 13 needs to be dug between the original ditch and the farmland. After the frame 11 is inserted, the outlet pipes 13 are simultaneously buried in the trench, and then the trench is covered by backfilling and compaction. The frame 11 is then fixed with anchor bolts 15, and a sealant (such as an inflated hollow air column 115) ensures a seal between the frame 11 and the inner wall of the ditch. The intercepting plate 12 is inserted into the slot 110, and then a water pump is used to drain or pump out the water between the two sealing units 1, creating a waterless construction area.

[0051] After the upstream water flow is intercepted, the water level rises. Under pressure, the water undergoes preliminary filtration through the filter screen 113 on the interceptor plate 12, and then enters the interior of the filter pipe 18 through the filter holes on its surface. The water flowing into the filter pipe 18 flows to the downstream sealing unit through the outlet pipe 13, the bend pipe 14, and the connecting pipe 2. It is then discharged into the downstream ditch through the outlet pipe 13 and the filter pipe 18 of the downstream sealing unit, or it can be directly led out to the farmland for irrigation through the drain valve 3 installed on the connecting pipe 2. When the outer surface of the filter pipe 18 is blocked by the accumulation of impurities, the construction personnel can manually move the lever 43 back and forth to move the ring 41 along the outer surface of the filter pipe 18, and use the brush bristles 44 to scrape away the blockage outside the filter holes to achieve cleaning.
