Detailed Embodiments

[0033] The following further describes the present application in detail in conjunction with the accompanying drawings and specific embodiments:

[0034] As Figures 1-3 shown, the prefabricated and assembled water channel of the present invention includes a plurality of spliced and assembled water channel bodies 1.

[0035] The water channel body 1 includes a water channel bottom plate, a water channel cover plate 30 and two water channel side plates; the water channel bottom plate and the two water channel side plates are cast in situ into an integral U-shaped structure 31; both ends of the water channel cover plate 30 are respectively placed on the tops of the two water channel side plates; an opening and closing type flow disturbing device is arranged on the inner side of the water channel cover plate 30.

[0036] The top of the water channel side plate is provided with a casting counterbore, and the part of the water channel cover plate 30 placed on the water channel side plate is provided with a casting through hole aligned with the casting counterbore; a steel bar 29 is anchored in the casting counterbore, and the steel bar 29 extends into the casting through hole; the water channel body further includes concrete filling the casting counterbore and the casting through hole.

[0037] A rubber water stop 2 is arranged inside the splicing joint 6 of two spliced water channel bodies 1; a high-pressure jet dredging pipe network 3 is arranged at the bottom of the spliced and assembled water channel bodies 1; an opening and closing type flow disturbing device is arranged inside the water channel body 1.

[0038] As Figure 2 、 Figure 4 shown, the opening and closing type flow disturbing device includes a baffle plate 4 and a hydraulic rod 5; one end of the baffle plate 4 is hinged to the water channel body 1, and the other end is hinged to one end of the hydraulic rod 5, and the other end of the hydraulic rod 5 is hinged to the water channel body 1 for driving the baffle plate 4 to open and close. The flow disturbing plate is arranged at the inner top of the water channel body 1, and the hydraulic rod 5 is arranged on the back water surface of the flow disturbing plate. When it is necessary to form a turbulent flow, the hydraulic rod 5 extends, so that the baffle plate 4 descends to the state as shown in Figure 4 shown, at least a part of the baffle plate 4 extends into the water flowing through the water channel body 1. When the water body encounters the blockage of the baffle plate 4, a turbulent flow is formed and flows around. Part of the water body impacts downward to the bottom of the water channel body 1, scouring the silt at the bottom and the side wall of the water channel body 1. The turbid water body at the bottom is quickly carried away by the water body, achieving the effect of dredging; in addition, it can also play the role of scouring the high-pressure jet dredging pipe network 3, avoiding the blockage or covering of the high-pressure jet dredging pipe network 3 by silt and ensuring the dredging effect.

[0039] In some embodiments, the baffle plate 4 can also be arranged on the side wall or the bottom of the water channel body 1, or arranged in a circle along the circumference of the water channel body 1, and the high-efficiency dredging of the water channel body 1 is realized by alternately opening and closing or synchronously opening and closing. Of course, the opening and closing type flow disturbing device further includes a hydraulic cylinder for driving the hydraulic rod 5 to extend and retract and the corresponding electrical control components. The hydraulic cylinder and the electrical control components can be arranged outside the water channel body 1, and through holes can be arranged at the top of the water channel body 1 to facilitate the laying or penetration of pipelines.

[0040] In some embodiments, a silt sensor is provided on the side wall or bottom of the water channel body 1. The silt sensor is electrically connected to a controller, and the controller is electrically connected to the opening and closing type flow disturbing device and the high-pressure jet dredging pipe network 3. When the silt sensor detects that the silt thickness reaches the target value, the controller starts the opening and closing type flow disturbing device and the high-pressure jet dredging pipe network 3 to realize automatic dredging.

[0041] As Figure 2 , Figure 3 shown, the high-pressure jet dredging pipe network 3 includes a pipe network unit provided at the bottom of each water channel body 1 and a connecting component connecting adjacent pipe network units; the pipe network unit includes a main pipe 7, one or more branch pipes 8 communicating with the main pipe 7, and high-pressure nozzles 9 provided on the branch pipes 8; at least one connecting component is also communicated with a high-pressure water pump 10; the high-pressure water pump 10 is also connected to a water supply pipe, and the end of the water supply pipe is connected with a floating ball. The floating ball is located in the water channel body 1. Under the action of the water body in the water channel body 1, the floating ball floats, so that the high-pressure water pump 10 can extract the water body in the water channel body 1 to the pipe network unit through the water supply pipe, realizing high-pressure jet dredging while not wasting water resources, being energy-saving and environment-friendly. A filter screen can also be provided at the end of the water supply pipe to filter the sediment in the water body and avoid clogging of the pipe network unit.

[0042] As Figure 4 , Figure 5 , Figure 7 shown, the rubber water stop 2 includes a curved flexible part 11 and fixing components provided on both sides of the flexible part 11; the flexible part 11 covers the splicing seam 6, and the fixing components on both sides of it are respectively fixedly connected to the water channel body 1 on both sides of the splicing seam 6.

[0043] The fixing components include a limiting strip 12, a pressing strip 13 and a fastener 14;

[0044] The limiting strip 12 is laid on the inner wall of the water channel body 1 and abuts against the side end of the flexible part 11; the length direction of the limiting strip 12 is the same as the length direction of the splicing seam 6 and also the same as the paving direction of the rubber water stop 2. When the rubber water stop 2 is paved, there is partial overlap between its head and tail sections to ensure the waterproof effect.

[0045] One end of the flexible part 11 facing away from the water channel body 1 is provided with a third groove 19; one end of the flexible part 11 facing away from the water channel body 1 is the water-facing surface of the flexible part 11.

[0046] One end of the pressing strip 13 is embedded in the third groove 19, and the other end is pressed against the upper end of the limiting strip 12; the pressing strip 13 is an n-shaped rubber strip.

[0047] The fastener 14 fastens the limiting strip 12 and the water channel body 1. The fastener 14 also fastens the pressing strip 13, the limiting strip 12 and the water channel body 1. The fastener 14 also fastens the pressing strip 13, the flexible part 11 and the water channel body 1. In this embodiment, the fastener 14 can be a fastening bolt.

[0048] The pressing strip 13 and the flexible part 11 are fixed by the fastener 14. The limiting strip 12 abuts against the flexible part 11, and then the limiting strip 12 and the water channel body 1 are fixed by the fastener 14 to limit the movement of the flexible part 11 along the water flow direction, that is, to limit the displacement of the flexible part 11 in the direction perpendicular to the splicing joint 6. The flexible part 11 adopts a curved surface structure, which has a plurality of wave crest parts and wave trough parts, and can effectively absorb the extrusion force or tensile force of the axial displacement of the spliced water channel body 1, and the axial direction is the water flow direction. The settlement or cracking of the foundation will affect the later splicing quality of the water channel body 1, and gaps or drops are likely to appear at the splicing joint 6. However, the flexible part 11 adopted in this embodiment can well adapt to the displacement of the splicing joint 6 and ensure the waterproof effect.

[0049] The end face of the water channel body 1 in contact with the limiting strip 12 is provided with a second groove 17, and the limiting strip 12 is provided with a second protrusion 18 embedded in the second groove 17. By arranging the second groove 17 cooperating with the limiting strip 12 on the water-facing surface of the water channel body 1, the displacement of the limiting strip 12 can be further restricted to ensure that the limiting strip 12 is closely attached to the flexible part 11. When the flexible part 11 is deformed by pressure or tension, the limiting strip 12 always keeps abutting against the flexible part 11. In addition, the limiting strip 12 is made of rubber material, which can further absorb the deformation energy of the flexible part 11 and prolong the service life of the rubber water stop 2.

[0050] The side end of the flexible part 11 abutting against the limiting strip 12 is provided with a first protrusion 16 extending towards the water channel body 1; the inner wall of the water channel body 1 is provided with a first groove 15 along the splicing joint 6; the first protrusion 16 is filled in the first groove 15. The depth of the first groove 15 is deeper than the depth of the second groove 17.

[0051] The inner wall of the water channel body 1 is provided with a notch groove 20 at the splicing joint 6; one end of the flexible part 11 facing the water channel body 1 is provided with a support limiting part 21; the support limiting part 21 extends into the notch groove 20 and abuts against the end face of the notch groove 20; the support limiting part 21 is located between the first protrusion 16 and the splicing joint 6.

[0052] On the back water surface of the flexible part 11, there are a first convex part 16 and a second convex part 18 that maintain a spacing. The convex height of the second convex part 18 is higher than that of the first convex part 16. The first convex part 16, the second convex part 18 and the flexible part 11 are of an integrally formed structure. Both the first convex part 16 and the second convex part 18 are continuously arranged along the length direction of the splicing seam 6. Rubber rib strips are also arranged on both sides of the first convex part 16. The rubber rib strips make the connection between the first convex part 16 and the first groove 15 tighter, limit the vertical displacement of the first convex part 16, and further limit the vertical displacement of the flexible part 11. Even if there is a drop in the water channel body 1 on both sides of the splicing seam 6, the rubber water stop 2 still has a good waterproof effect.

[0053] Under the multiple barriers of the first groove 15, the first convex part 16, the second groove 17 and the second convex part 18, the water body inside the water channel body 1 is difficult to penetrate through the splicing seam 6 to the outside, and has a good waterproof effect.

[0054] An inner support strip 22 is also arranged between the flexible part 11 and the splicing seam 6; the inner support strip 22 is supported between the support limiting parts 21 on both sides of the flexible part 11. The length direction of the inner support strip 22 is the same as the length direction of the splicing seam 6, and the inner support strip 22 is also made of rubber material. One side wall of the support limiting part 21 abuts against the side wall of the notch groove 20, and the other side wall is abutted by the inner support strip 22, so that the support limiting part 21 is fixed and is closely matched with the notch groove 20 to improve the waterproof property. Especially, the inner support strip 22 can be supported on the back water surface of the flexible part 11. When the water surface of the flexible part 11 is subjected to water pressure, the inner support strip 22 provides effective support to prevent the flexible part 11 from being excessively deformed and causing an increase in the gap between the contact surface with the water channel body 1 and affecting the waterproof effect.

[0055] As Figure 5 、 Figure 6 shown, the connecting component includes a sleeve 23 and two L-shaped pipes respectively threadedly connected to both ends of the sleeve 23; the sleeve 23 is located in the notch groove 20; the other ends of the two L-shaped pipes are respectively communicated with the main pipes 7 of two adjacent pipe network units. The L-shaped pipe includes a positioning pipe 24 and a connecting pipe 25; the upper end of the positioning pipe 24 is fixedly communicated with the main pipe 7; an L-shaped positioning hole 26 is arranged on the inner wall of the water channel body 1; the L-shaped positioning hole 26 includes a vertical hole and a horizontal hole; the lower end of the positioning pipe 24 is inserted into the vertical hole, and the connecting pipe 25 extends into the horizontal hole. One end of the connecting pipe 25 is threadedly connected to the positioning pipe 24, and the other end is threadedly connected to the sleeve 23. The connecting pipe 25 penetrates through the support limiting part 21; rubber pads 27 and compression nuts 28 that are clamped on both sides of the support limiting part 21 are arranged on the connecting pipe 25.

[0056] The L-shaped positioning hole 26 is preset on the water channel body 1 in advance, and the main pipeline 7 and the branch pipeline 8 can also be pre-assembled. The positioning pipe 24 can be welded to the bottom of the main pipeline 7 in advance; when assembling the high-pressure jet dredging pipe network 3, the positioning pipe 24 at the bottom of the main pipeline 7 of the pipe network unit of the water channel body 1 is vertically inserted into the vertical hole of the L-shaped positioning hole 26, and the positioning of the pipe network unit can be completed. Then, the connecting pipe 25 that is threadedly matched with the positioning pipe 24 is inserted into the horizontal hole of the L-shaped positioning hole 26, and the connecting pipe 25 and the positioning pipe 24 are tightened at the notch groove 20 to complete the assembly of the L-shaped pipeline. In this state, a part of the connecting pipe 25 extends into the notch groove 20. Of course, before the connecting pipe 25 penetrates into the horizontal hole, a compression nut 28 is pre-tightened on the threaded section of the connecting pipe 25, and then the rubber gasket 27 is placed between the support and limit part 21 and the side wall of the notch groove 20. The connecting pipe 25 passes through the support and limit part 21 and the rubber gasket 27 in sequence and then is inserted into the horizontal hole and is threadedly connected with the positioning pipe 24. Then, the compression nut 28 is tightened to make the compression nut 28 press the support and limit part 21. Finally, the sleeve 23 is used to connect the connecting pipes 25 of two L-shaped pipelines to realize the connection of two pipe network units. At the same time, the rubber water stop 2 is also effectively fixed, and the rubber water stop 2 seals the space formed by splicing the notch grooves 20 of adjacent two water channel bodies 1 to prevent water from seeping into this space, rusting the connection components, and also facilitating later inspection and maintenance.

[0057] Based on the same inventive concept, the present invention also provides a construction method for the above-mentioned assembled water channel, including the following steps:

[0058] Step 1, prefabricate the U-shaped structure 31 and the water channel cover plate 30 of the water channel body 1;

[0059] Step 2, pre-embed the pipe network unit of the high-pressure jet dredging pipe network 3 at the bottom of the water channel body 1, that is, inside the U-shaped structure 31; install the opening and closing flow disturbing device on the inside of the water channel cover plate 30.

[0060] Step 3, hoist multiple U-shaped structures 31 to the target position in sequence and splice adjacent U-shaped structures 31; hoist a water channel cover plate 30 on the upper end of each U-shaped structure 31, and pour concrete into the cast counterbore and the cast through hole to complete the connection between the water channel cover plate 30 and the U-shaped structure 31.

[0061] Step 4, use the connection components to connect adjacent pipe network units; according to the number of water channel bodies 1, determine the number of connection components, and use the connection components to connect all the pipe network units of the water channel bodies 1 into a whole.

[0062] Step 5: Lay the flexible part 11 of the rubber waterstop 2 inside the splicing joint 6 of the water channel body 1, and make the flexible part 11 cover the connecting component. Fix the flexible part 11 and the water channel body 1 by using the fixing component. The rubber waterstops 2 are lap jointed end to end. The inner wall of the water channel body 1 is coated with a nano-penetrating crystalline waterproof coating to enhance the impermeability of the concrete.

[0063] Step 6: Connect the high-pressure water pump 10 with the connecting component in the water channel body 1 at the end. When the number of spliced water channel bodies 1 is large, the number of high-pressure water pumps 10 can be appropriately increased as needed. For example, one high-pressure water pump 10 is configured for every ten water channel bodies 1. For the connecting component that needs to install the high-pressure water pump 10, a three-way joint is arranged on the corresponding connecting pipe 25 and then connected with the high-pressure water pump 10, and the construction is simple and flexible.

[0064] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
