Description

Technical Field

[0001] This application relates to the field of culvert water diversion device technology, and in particular to a modular portable water diversion device. Background Technology

[0002] In highway construction, culverts, as an important structural element, play a crucial role in ensuring that highways can smoothly cross waterways without disrupting traffic. They are typically designed and built beneath the roadbed, forming a water passage beneath the road surface. This ingenious structure allows water to flow freely beneath the highway, ensuring both the road's stability and effectively maintaining the natural flow of water systems. Culverts are widely used to cross naturally formed valleys and depressions to drain seasonal or sudden floods. They are also frequently used as grade-separated intersections across roads of various sizes, facilitating the passage of people, livestock, and vehicles.

[0003] However, in actual construction, especially when facing complex situations requiring extended culvert lengths or adjustments to water flow direction, efficiently and economically guiding water flow from culverts to other culverts or natural waterways becomes a technical challenge. Traditional solutions often involve temporary land acquisition to construct additional diversion channels, a process that is not only costly but can also lead to land use disputes and environmental damage. Another common approach is to use pumps for drainage. While this method can address water diversion to some extent, it is highly energy-intensive, complex to operate, and time-consuming. Furthermore, in large-scale or long-term construction projects, the demand for manpower and resources increases significantly, severely restricting construction efficiency and extending project cycles. Utility Model Content

[0004] This application provides a modular portable water diversion device to solve the problem that the difficulty of diverting water in extended culverts affects construction efficiency.

[0005] This application provides a modular portable water guiding device, including: a water blocking device and a flow guiding device;

[0006] The water-blocking device is installed at the inlet of the culvert, and the water-blocking device includes multiple first water-blocking sections and two second water-blocking sections;

[0007] Multiple first water-blocking sections and two second water-blocking sections are spliced ​​together to form a strip structure, and the multiple first water-blocking sections are located in the middle of the two second water-blocking sections;

[0008] Both the first and second water-blocking sections have L-shaped cross-sections; the first water-blocking section has a water guide on the side near the culvert inlet, and the water guide is threadedly connected to the flow guiding device.

[0009] The aforementioned portable water diversion device quickly connects the water-blocking device and the flow-diverting device at the inlet of the extended culvert, allowing the water flow to accumulate and be diverted by gravity to the outside of the construction area. This eliminates the need for temporary land acquisition or water pumping, while still meeting the diversion requirements and ensuring that the construction area of ​​the extended culvert is not affected by the water flow. This solves the problem of the difficulty in diverting water in extended culverts, which affects construction efficiency.

[0010] Optionally, the first water-blocking section includes a first water-blocking plate and a first water pressure plate; both the first water-blocking plate and the first water pressure plate are rectangular plates made of rigid plastic, and the lengths of the first water-blocking plate and the first water pressure plate are equal; the water inlet is opened at the center of the first water-blocking plate; the first water pressure plate is disposed on the bottom surface of the culvert, the first water-blocking plate and the first water pressure plate are perpendicular to each other, and the bottom of the first water-blocking plate is fixedly connected to the side of the first water pressure plate near the culvert inlet.

[0011] By combining the first water-blocking plate with the first water pressure plate, the water flow entering from the culvert inlet can be effectively blocked, preventing the water flow from directly impacting the interior of the culvert and enhancing its waterproof capability. The water guide is located in the center of the first water-blocking plate, which can guide a small amount of water entering the area of ​​the first water-blocking plate to a specific direction, further optimizing the drainage path and preventing water from accumulating at the culvert inlet, thereby improving the overall waterproof performance of the culvert.

[0012] Optionally, the second water-blocking section includes a second water-blocking plate and a second water pressure plate; both the second water-blocking plate and the second water pressure plate are rectangular plates made of rigid plastic, and the lengths of the second water-blocking plate and the second water pressure plate are equal; the second water pressure plate is disposed on the bottom surface of the culvert, the second water-blocking plate and the second water pressure plate are perpendicular to each other, and the bottom of the second water-blocking plate is fixedly connected to the side of the second water pressure plate near the culvert inlet.

[0013] By combining the second water baffle with the second water pressure plate, the water flow entering from the culvert inlet can be effectively blocked, preventing the water flow from directly impacting the inside of the culvert and enhancing the culvert's waterproof capability.

[0014] Optionally, a first concave latch is provided on one side of the first water-blocking section, and a first convex latch is provided on the side of the first water-blocking section away from the first concave latch; a second concave latch is provided on one side of the second water-blocking section, and a second convex latch is provided on the side of the second water-blocking section away from the second concave latch; adjacent first concave latches or second concave latches are engaged with the first convex latches or second convex latches.

[0015] The first concave clip, the second concave clip, the first convex clip, and the second convex clip allow the first water-blocking section and the second water-blocking section to be arbitrarily spliced ​​according to the width of the culvert. This not only allows for flexible handling of culverts of different sizes but also facilitates transportation. Installation can be completed through simple snap-fit ​​operations, shortening installation time, improving construction efficiency, and reducing the workload and construction difficulty on the construction site.

[0016] Optionally, the first water-blocking section is provided with two first reinforcing ribs; the second water-blocking section is provided with two second reinforcing ribs; both the first and second reinforcing ribs are L-shaped glass fiber reinforcing ribs, the first reinforcing ribs are parallel to the side of the first water-blocking section; the second reinforcing ribs are parallel to the side of the second water-blocking section.

[0017] Both the first and second reinforcing ribs are L-shaped structures, which increase the moment of inertia of the cross-section of the water-blocking device. This allows it to more effectively resist bending deformation when subjected to bending moments, ensuring that the water-blocking device maintains a stable structural shape even under complex stress conditions. The first and second reinforcing ribs are parallel to the side of the first water-blocking section, effectively dispersing and bearing the impact force from water flow and soil pressure, enabling it to better cope with various external forces and maintain structural integrity.

[0018] Optionally, the width of both the first and second water-blocking sections is 1 meter.

[0019] The aforementioned widths of the first and second water-retaining sections not only enable mass production, facilitate on-site installation, and simplify maintenance and replacement, but also provide a suitable cross-sectional area to distribute stress, improve the structural stability of the drainage system, extend its service life, and reduce safety risks. Furthermore, the 1-meter width ensures ideal mechanical properties of the first and second water-retaining sections under bending, tensile, and compressive stresses, improving bending stiffness, compressive and tensile strength, and maintaining structural integrity.

[0020] Optionally, the flow guiding device includes a flow guiding belt and a connecting port; the flow guiding belt is a cylindrical structure made of polyester fiber; the connecting port is a ring-shaped structure made of rigid plastic; one end of the flow guiding belt is fixed to one end of the connecting port, the other end of the connecting port has an external thread on its inner side, the water guide port has an internal thread on its outer side, and the external thread of the connecting port is connected to the internal thread of the water guide port.

[0021] The polyester fiber guide strip can adapt to the deformation and displacement of the culvert under different working conditions without affecting its guiding function, ensuring the reliability and adaptability of the guiding device in complex environments. The connection port is a ring-shaped structure made of rigid plastic, which facilitates a tight connection with the water inlet and also helps to disperse the force of the water flow on the connection port, further enhancing the structural stability of the entire guiding device.

[0022] Optionally, the water-blocking device and the flow-guiding device are provided with an anti-corrosion coating; the anti-corrosion coating is uniformly disposed on the inner and outer surfaces of the water-blocking device and the flow-guiding device.

[0023] The anti-corrosion coating improves corrosion resistance, enhances device stability, reduces maintenance costs, helps extend the service life of the entire water guiding device, and improves its reliability.

[0024] Optionally, a telescopic water-blocking section is provided on the side of the second water-blocking section away from the first water-blocking section; a slider is provided on the telescopic water-blocking section; a chute is provided on the side of the second water-blocking section near the culvert inlet, and the telescopic water-blocking section is connected to the second water-blocking section through the slider and the chute.

[0025] The sliding block and the groove allow the telescopic water-blocking section to extend and retract freely in a direction away from the first water-blocking section, thereby enabling the assembled water guiding device to adapt to culvert openings of different sizes.

[0026] As can be seen from the above technical solutions, this application provides a splicing portable water guiding device, including: a water blocking device and a flow guiding device; the water blocking device is set at the inlet of the culvert, and the water blocking device includes multiple first water blocking sections and two second water blocking sections; the multiple first water blocking sections and the two second water blocking sections are spliced ​​into a strip structure, and the multiple first water blocking sections are located in the middle of the two second water blocking sections; the cross-sections of the first water blocking sections and the second water blocking sections are both L-shaped structures; a water guiding port is provided on the side of the first water blocking section near the inlet of the culvert, and the water guiding port is threadedly connected to the flow guiding device, so as to solve the problem that the difficulty of water flow guiding in the extended culvert affects the construction efficiency.

Detailed Implementation

[0035] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0036] A culvert is a water passage built under the roadbed in highway construction to allow water to flow under the road surface without obstructing traffic. Culverts are used to drain floodwaters across natural valleys and depressions, or to cross roads of various sizes as overpasses for people, livestock, and vehicles.

[0037] In related embodiments, a common practice involves temporary land acquisition to construct additional diversion channels. This process is not only costly but may also lead to land use rights disputes and environmental damage. Another common practice is to use water pumps for drainage operations. While this method can solve the water diversion problem to some extent, it is extremely energy-intensive, complex to operate, and time-consuming. In large-scale or long-term construction projects, the demand for manpower and resources increases significantly, severely restricting construction efficiency and extending the project cycle.

[0038] To address the issue of the significant difficulty in diverting water flow during extended culvert construction, which impacts construction efficiency, see [reference needed]. Figures 1-5This application provides a portable water-guiding device, including: a water-blocking device and a flow-guiding device 3; the water-blocking device is disposed at the inlet of a culvert, and the water-blocking device includes a plurality of first water-blocking sections 1 and two second water-blocking sections 2; the plurality of first water-blocking sections 1 and two second water-blocking sections 2 are spliced ​​into a strip structure, and the plurality of first water-blocking sections 1 are located in the middle of the two second water-blocking sections 2; the cross-sections of the first water-blocking sections 1 and the second water-blocking sections 2 are both L-shaped structures; a water-guiding port 13 is provided on the side of the first water-blocking section 1 near the inlet of the culvert, and the water-guiding port 13 is threadedly connected to the flow-guiding device 3.

[0039] It should be understood that the diameter of the water inlet 13 can be selected according to the water flow rate. Construction workers can first splice the second water-blocking section 2, several first water-blocking sections 1, and second water-blocking sections 2 sequentially from one side of the extended culvert inlet to the other side, and then install the flow guiding device 3 on the first water-blocking section 1 so that the water flow passes sequentially through the old culvert, the construction area, and outside the construction area.

[0040] The portable water diversion device is quickly spliced ​​with the water-blocking device and the flow-diverting device 3 at the inlet of the extended culvert, allowing the water flow to accumulate and be diverted to the outside of the construction area by gravity through the flow-diverting device 3. This not only eliminates the need for temporary land acquisition or water pumping, but also meets the diversion requirements, ensuring that the construction area of ​​the extended culvert is not affected by the water flow, thus solving the problem of the difficulty in diverting water in extended culverts and affecting construction efficiency.

[0041] In some embodiments, the first water-blocking section 1 includes a first water-blocking plate 11 and a first water pressure plate 12; the first water-blocking plate 11 and the first water pressure plate 12 are both rectangular plates made of rigid plastic, and the lengths of the first water-blocking plate 11 and the first water pressure plate 12 are equal; the water inlet 13 is opened at the center of the first water-blocking plate 11; the first water pressure plate 12 is disposed on the bottom surface of the culvert, the first water-blocking plate 11 and the first water pressure plate 12 are perpendicular to each other, and the bottom of the first water-blocking plate 11 is fixedly connected to the side of the first water pressure plate 12 near the water inlet of the culvert.

[0042] It should be understood that the rigid plastic material can be high-density polyethylene, which has good durability and stability, can withstand certain water flow pressure and environmental erosion, and is not easily deformed or damaged. At the same time, its material properties also facilitate daily maintenance and inspection; if damage or aging is found, it can be replaced in a timely manner to ensure normal water flow in the culvert. Both the first water-blocking plate 11 and the first water pressure plate 12 are rectangular plates made of rigid plastic, with regular shapes and equal lengths. This design makes installation more convenient and quick, allowing for accurate and precise fixing of the first water-blocking plate 11 and the first water pressure plate 12 in their respective positions, reducing installation difficulty and time costs.

[0043] By cooperating with the first water baffle 11 and the first water pressure plate 12, the water flow entering from the culvert inlet can be effectively blocked, preventing the water flow from directly impacting the interior of the culvert and enhancing the culvert's waterproof capability. The water guide 13 is located in the center of the first water baffle 11, which can guide a small amount of water entering the area of ​​the first water baffle 11 to a specific direction, further optimizing the drainage path and preventing water from accumulating at the culvert inlet, thereby improving the overall waterproof performance of the culvert.

[0044] In some embodiments, the second water-blocking section 2 includes a second water-blocking plate 21 and a second water pressure plate 22; the second water-blocking plate 21 and the second water pressure plate 22 are both rectangular plates made of rigid plastic, and the lengths of the second water-blocking plate 21 and the second water pressure plate 22 are equal; the second water pressure plate 22 is disposed on the bottom surface of the culvert, the second water-blocking plate 21 and the second water pressure plate 22 are perpendicular to each other, and the bottom of the second water-blocking plate 21 is fixedly connected to the side of the second water pressure plate 22 near the culvert inlet.

[0045] It should be understood that the rigid plastic material can be high-density polyethylene, which has good durability and stability, can withstand certain water flow pressure and environmental erosion, and is not easily deformed or damaged. At the same time, its material properties also facilitate daily maintenance and inspection; if damage or aging is found, it can be replaced in a timely manner to ensure normal water flow in the culvert. Both the second water-blocking plate 21 and the second water pressure plate 22 are rectangular plates made of rigid plastic, with regular shapes and equal lengths. This design makes installation more convenient and quick, allowing for accurate and precise fixing of the second water-blocking plate 21 and the second water pressure plate 22 in their respective positions, reducing installation difficulty and time costs.

[0046] By combining the second water baffle 21 with the second water pressure plate 22, the water flow entering from the culvert inlet can be effectively blocked, preventing the water flow from directly impacting the inside of the culvert and enhancing the culvert's waterproof capability.

[0047] In some embodiments, a first concave latch 14 is provided on one side of the first water-blocking section 1, and a first convex latch 15 is provided on the side of the first water-blocking section 1 away from the first concave latch 14; a second concave latch 24 is provided on one side of the second water-blocking section 2, and a second convex latch 25 is provided on the side of the second water-blocking section 2 away from the second concave latch 24; adjacent first concave latch 14 or second concave latch 24 are engaged with first convex latch 15 or second convex latch 25.

[0048] Specifically, the first concave clip 14, the second concave clip 24, the first convex clip 15, and the second convex clip 25 are all L-shaped structures, and all are parallel to the side of the first water-blocking section 1 and the side of the second water-blocking section 2. The L-shaped structure allows the first water-blocking section 1 and the second water-blocking section 2 to be connected more tightly, making them less prone to loosening or displacement under water flow impact or external force, effectively enhancing the overall structural stability. In addition, since the above clips are all L-shaped structures and parallel to the side of the water-blocking section, it is convenient for subsequent alignment and installation, increasing the reliability of installation.

[0049] The first concave clip 14, the second concave clip 24, the first convex clip 15, and the second convex clip 25 allow the first water-blocking section 1 and the second water-blocking section 2 to be arbitrarily spliced ​​according to the width of the culvert. This not only allows for flexible handling of culverts of different sizes but also facilitates transportation. Installation can be completed through simple snap-fit ​​operations, shortening installation time, improving construction efficiency, and reducing the workload and construction difficulty on the construction site.

[0050] In some embodiments, the first water-blocking section 1 is provided with two first reinforcing ribs 16; the second water-blocking section 2 is provided with two second reinforcing ribs 23; the first reinforcing ribs 16 and the second reinforcing ribs 23 are both L-shaped glass fiber reinforcing ribs, the first reinforcing ribs 16 are parallel to the side of the first water-blocking section 1; the second reinforcing ribs 23 are parallel to the side of the second water-blocking section 2.

[0051] It should be understood that fiberglass reinforced bars are composed of fiberglass and resin, possessing excellent corrosion resistance and high energy absorption capacity. Furthermore, while their density is significantly lower than that of steel reinforcement, their strength is comparable to high-strength steel. This results in less material being required to bear the same load, thus reducing the structure's self-weight, facilitating construction and transportation, and lowering construction difficulty and costs.

[0052] Both the first reinforcing rib 16 and the second reinforcing rib 23 are L-shaped structures, which can increase the moment of inertia of the cross-section of the water-blocking device, enabling it to more effectively resist bending deformation when subjected to bending moment, and ensuring that the water-blocking device can maintain a stable structural shape under complex stress conditions. The first reinforcing rib 16 and the second reinforcing rib 23 are parallel to the side of the first water-blocking section 1, which can effectively disperse and withstand the impact force from water flow and soil pressure, enabling it to better cope with various external forces and maintain structural integrity.

[0053] In some embodiments, the width of both the first water-blocking section 1 and the second water-blocking section 2 is 1 meter.

[0054] The aforementioned widths of the first and second water-retaining sections 1 and 2 not only enable mass production, facilitate on-site installation, and simplify maintenance and replacement, but also provide suitable cross-sectional areas to distribute stress, improve the structural stability of the drainage system, extend its service life, and reduce safety risks. Furthermore, the 1-meter width ensures ideal mechanical properties of the first and second water-retaining sections 1 and 2 under bending, tensile, and compressive stresses, improving bending stiffness, compressive strength, and tensile strength while maintaining structural integrity.

[0055] In some embodiments, the flow guiding device 3 includes a flow guiding band 31 and a connecting port 32; the flow guiding band 31 is a cylindrical structure made of polyester fiber; the connecting port 32 is a ring-shaped structure made of rigid plastic; one end of the flow guiding band 31 is fixed to one end of the connecting port 32, the other end of the connecting port 32 is provided with an external thread on its inner side, the water guide port 13 is provided with an internal thread on its outer side, and the external thread of the connecting port 32 is connected to the internal thread of the water guide port 13.

[0056] It should be understood that polyester fiber, due to its good wear resistance, corrosion resistance, and certain flexibility, can adapt to different working environments. The cylindrical structure provides a smoother flow channel, reducing water resistance during flow and allowing water to pass through the flow guide device 3 more efficiently, thus improving drainage efficiency. The polyester fiber flow guide strip 31 can adapt to the deformation and displacement of the culvert under different working conditions. For example, under conditions of water flow impact, temperature changes, or foundation settlement, the flow guide strip 31 can bend or deform to a certain extent without affecting its flow guiding function, ensuring the reliability and adaptability of the flow guide device 3 in complex environments. The length of the flow guide strip 31 can be determined according to the length of the construction area. When renovating, expanding, or lengthening the culvert, the water flow can sequentially pass through the old culvert, the construction area, and finally be discharged outside the construction area.

[0057] Because rigid plastic has high strength and stability, it ensures that the connection port 32 is not easily deformed or damaged during connection and flow guidance. The connection port 32 is a ring-shaped structure made of rigid plastic, which facilitates a tight connection with the water inlet 13, and also helps to disperse the force of water flow on the connection port 32, further enhancing the structural stability of the entire flow guiding device 3.

[0058] In some embodiments, the water-blocking device and the flow-guiding device 3 are provided with an anti-corrosion coating; the anti-corrosion coating is uniformly disposed on the inner and outer surfaces of the water-blocking device and the flow-guiding device 3.

[0059] It should be understood that the anti-corrosion coating may be an epoxy resin coating or a polyurethane coating. The anti-corrosion coating can improve corrosion resistance, enhance device stability, reduce maintenance costs, help extend the service life of the entire water guiding device, and improve its reliability.

[0060] In some embodiments, the second water-blocking section 2 is provided with a telescopic water-blocking section on the side away from the first water-blocking section 1; the telescopic water-blocking section is provided with a slider; the second water-blocking section 2 is provided with a chute on the side near the culvert inlet, and the telescopic water-blocking section is connected to the second water-blocking section 2 through the slider and the chute.

[0061] It should be understood that the telescopic water-blocking section is also a rectangular plate made of rigid plastic with an L-shaped cross-section. The telescopic water-blocking section can freely extend and retract in a direction away from the first water-blocking section 1 via the slider and the groove, thereby allowing the assembled water guiding device to adapt to culvert openings of different sizes.

[0062] In some other embodiments, the second water-blocking section 2 can be cut according to the specific size of the culvert so that the spliced ​​water guiding device can adapt to the culvert opening of different sizes.

[0063] As can be seen from the above technical solutions, this application provides a splicing portable water guiding device, including: a water blocking device and a flow guiding device 3; the water blocking device is set at the inlet of the culvert, and the water blocking device includes multiple first water blocking sections 1 and two second water blocking sections 2; the multiple first water blocking sections 1 and the two second water blocking sections 2 are spliced ​​into a strip structure, and the multiple first water blocking sections 1 are located in the middle of the two second water blocking sections 2; the cross-sections of the first water blocking sections 1 and the second water blocking sections 2 are both L-shaped structures; a water guiding port 13 is provided on the side of the first water blocking section 1 near the inlet of the culvert, and the water guiding port 13 is threadedly connected to the flow guiding device 3, so as to solve the problem that the difficulty of water flow guidance in the extended culvert affects the construction efficiency.

The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
