Description

Technical Field

[0001] This invention relates to the field of water conservancy and hydropower engineering technology, and in particular to a livestock-proof bridge and a site isolation method using the livestock-proof bridge. Background Technology

[0002] During the construction and operation of water conservancy and hydropower projects, in order to ensure construction and operation safety, the construction site and traffic roads need to be closed. If some locations are connected to rural roads, entrances and exits need to be set up to reduce the impact on rural traffic.

[0003] For construction sites or roads that are large in area or long in length, or that are permanently used, complete closure management would cause inconvenience to pedestrians and small vehicles due to the long usage period. In addition, closure management requires the establishment of guard posts with dedicated personnel to temporarily open the entrances and exits when there is traffic demand, which leads to higher manual management costs. On the other hand, if open entrances and exits are set up and operated in an unmanned manner, the effect of keeping out large livestock is poor, which can easily bring safety hazards to the construction site or road traffic. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention provides a livestock-proof bridge that can prevent large livestock from passing through.

[0005] The present invention adopts the following technical solution:

[0006] This invention provides a livestock-proof bridge, comprising a support platform, a bridge frame, and guardrails. Two support platforms are arranged parallel to each other on a horizontal ground. The bridge frame is provided with multiple sinkholes connecting the top and bottom surfaces. The opening of each sinkhole is large enough to allow the animal's hoof to sink in freely. The bridge frame is suspended in the gap between the two support platforms, and the outer edges of both ends of the bridge frame are simultaneously connected and fixed to the two support platforms. Two guardrails are arranged parallel to each other on both sides of the bridge frame, and the guardrails are perpendicular to the support platforms.

[0007] Preferably, the support platform is stepped, and the outer edges of both ends of the bridge plate frame are respectively overlapped and fixed in the grooves of the two support platforms, and the top surface of the bridge plate frame is flush with the top surface of the two support platforms.

[0008] Preferably, the support platform is a concrete structure.

[0009] Preferably, the bridge plate frame includes a rectangular frame, transverse support pipes, and longitudinal support plates. Multiple transverse support pipes are arranged parallel and at equal intervals within the rectangular frame, and the transverse support pipes are parallel to the support platform. Multiple longitudinal support plates are arranged perpendicular to the transverse support pipes at intervals within the rectangular frame. The transverse support pipes and longitudinal support plates intersect to form multiple recesses. Both ends of the transverse support pipes and both ends of the longitudinal support plates are supported on the rectangular frame.

[0010] Preferably, the spacing between two adjacent transverse support pipes is 8-12cm, and the spacing between two adjacent longitudinal support plates is 0.5m-1.0m.

[0011] Preferably, two longitudinal fixing rods are symmetrically arranged inside the rectangular frame. Both longitudinal fixing rods are perpendicular to the transverse support tubes. Both ends of the transverse support tubes have through holes along their length. The longitudinal fixing rods pass through all the through holes at one end of multiple transverse support tubes.

[0012] The present invention also provides a site isolation method, which uses the above-mentioned livestock-proof bridge and includes the following steps:

[0013] S1: Set up a fence around the construction site or the road, and reserve entrances and exits at the junction of the construction site and the rural road or the junction of the road and the rural road.

[0014] S2: Excavate a flat-bottomed pit at the junction of the rural road and the construction site or at the junction of the rural road and the traffic road, and set the livestock-proof bridge in the flat-bottomed pit so that the bottom of the two support platforms are in contact with the flat-bottomed pit. The two guardrails are connected to the fence structure on both sides of the entrance and exit, and the bridge deck is flush with the rural road.

[0015] Preferably, in step S1, the enclosure structure is a construction site or traffic road guardrail, wire mesh, wall or hedge.

[0016] Preferably, in step S2, the height difference between the bridge plate frame and the flat-bottomed pit is 18-22cm.

[0017] Preferably, in step S2, the width of the bridge deck is the same as the width of the rural road.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] When in use, the livestock-proof bridge of the present invention needs to be embedded in the rural road as a whole, and the guardrails on both sides of the bridge deck are respectively connected to the entrance and exit of the enclosed area. At this time, if you want to enter the enclosed area from the rural road, you must pass through the livestock-proof bridge. The bridge deck of the livestock-proof bridge is equipped with multiple traps that allow the hooves of livestock to sink freely, so that large livestock cannot pass through the livestock-proof bridge normally, while pedestrians and small vehicles can still pass normally.

[0020] Clearly, the livestock-proof bridge of the present invention can effectively block large livestock without affecting the passage of pedestrians and small vehicles.

[0021] The site isolation method of the present invention combines the conventional traffic scheme of setting open entrances and exits and operating in an unmanned manner with the above-mentioned livestock-proof bridge, which not only reduces the long-term management cost, but also has a good blocking effect on large livestock.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] See Figure 1 This embodiment provides a livestock bridge, including a support platform 1, a bridge frame 2, and guardrails 3. Two support platforms 1 are set parallel to each other on a horizontal ground. The bridge frame 2 is provided with multiple sinkholes connecting the top and bottom surfaces. The opening of each sinkhole is large enough to allow the hooves of livestock to sink in freely. The bridge frame 2 is suspended in the gap between the two support platforms 1, and the outer edges of both ends of the bridge frame 2 are simultaneously connected and fixed to the two support platforms 1. Two guardrails 3 are set parallel to each other on both sides of the bridge frame 2, and the guardrails 3 are perpendicular to the support platforms 1.

[0037] In this embodiment, the livestock-proof bridge needs to be embedded into the rural road as a whole, and the guardrails 3 on both sides of the bridge frame 2 are connected to the entrance and exit ends of the enclosed area respectively. If you want to enter the enclosed area from the rural road, you must pass through the livestock-proof bridge. The bridge frame 2 of the livestock-proof bridge is equipped with multiple traps that allow the hooves of livestock to sink in freely, so that large livestock cannot pass through the livestock-proof bridge normally, while pedestrians and small vehicles can still pass normally.

[0038] Clearly, the livestock-blocking bridge in this embodiment can effectively prevent large livestock from passing without affecting the passage of pedestrians and small vehicles.

[0039] Preferably, see Figure 1 The support platform 1 has a stepped shape. The outer edges of both ends of the bridge plate frame 2 are respectively overlapped and fixed in the grooves of the two support platforms 1, and the top surface of the bridge plate frame 2 is flush with the top surface of the two support platforms 1, so as to protect the connection between the bridge plate frame 2 and the support platform 1 and improve the installation reliability of the bridge plate frame 2.

[0040] Preferably, the support platform 1 is a concrete structure.

[0041] It should be noted that in this embodiment, both the bridge plate frame 2 and the guardrail 3 are steel structures.

[0042] Preferably, in this embodiment, two support platforms 1 can also be arranged parallel to each other directly below the two guardrails 3, and the bottom of both sides of the bridge frame 2 can be connected and fixed to the two support platforms 1 at the same time, so as to effectively increase the load-bearing capacity of the livestock bridge and reduce the amount of steel used when making the bridge frame 2.

[0043] Preferably, see Figure 2 The bridge deck frame 2 includes a rectangular frame 21, transverse support pipes 22, and longitudinal support plates 23. Multiple transverse support pipes 22 are arranged parallel and at equal intervals within the rectangular frame 21, and the transverse support pipes 22 are parallel to the support platform 1. Multiple longitudinal support plates 23 are arranged perpendicularly to the transverse support pipes 22 and at intervals within the rectangular frame 21. The transverse support pipes 22 and the longitudinal support plates 23 intersect to form multiple recesses. Both ends of the transverse support pipes 22 and both ends of the longitudinal support plates 23 are supported on the rectangular frame 21, so that the load borne by the transverse support pipes 22 and the longitudinal support plates 23 is effectively transferred to the rectangular frame 21.

[0044] Specifically, see Figure 2 In this embodiment, a plurality of U-shaped grooves 231 are spaced apart on the longitudinal support plate 23, and each transverse support pipe 22 overlaps in a U-shaped groove 231, and the lower semi-circular structure of the U-shaped groove 231 is in contact with the pipe wall of the transverse support pipe 22.

[0045] Preferably, in this embodiment, the transverse support tube 22 is a two-inch circular seamless steel tube.

[0046] Preferably, the distance between two adjacent transverse support pipes 22 is 8-12cm, and the distance between two adjacent longitudinal support plates 23 is 0.5m-1.0m, so as to ensure the normal passage of pedestrians and small vehicles, while the hooves of large livestock can slide into the pit without being injured by getting stuck, and can be pulled out smoothly.

[0047] Specifically, in this embodiment, the distance between two adjacent transverse support tubes 22 is 10cm.

[0048] Better yet, see Figure 2 In this embodiment, there are four longitudinal support plates 23, which are grouped in pairs. The two groups of longitudinal support plates 23 are symmetrically arranged within the rectangular frame 21, with a spacing of 1m between the two groups and a spacing of 0.5m between each group. When a regular small vehicle enters the livestock protection bridge, the driving path of the wheels on both sides is controlled to be between the two longitudinal support plates 23 in each group, which can effectively increase the bending resistance of the transverse support pipe 22 and extend the service life of the bridge deck frame 2.

[0049] Preferably, see Figure 2Two longitudinal fixing rods 24 are symmetrically arranged inside the rectangular frame 21. Both longitudinal fixing rods 24 are perpendicular to the transverse support tubes 22. Both ends of the transverse support tubes 22 have through holes along their length. The longitudinal fixing rods 24 pass through all the through holes at one end of multiple transverse support tubes 22. The longitudinal fixing rods 24 connect all the transverse support tubes 22 inside the rectangular frame 21 into one unit. If the longitudinal fixing rods 24 are not removed, it is impossible to remove a single transverse support tube 22, which effectively enhances the integrity and safety of the transverse support tubes 22.

[0050] Better yet, see Figure 2 In this embodiment, the rectangular frame 21 includes closed plates 211 and peripheral support plates 212. Four closed plates 211 are joined together to form an outer frame, and four peripheral support plates 212 are joined together to form an inner frame. The inner frame is nested within the outer frame to form the rectangular frame 21. Semi-circular grooves are provided on the peripheral support plates 212 on both sides of the inner frame, and the transverse support pipes 22 are installed in the semi-circular grooves. Square slots and locking slots are provided on the peripheral support plates 212 on both sides of the inner frame, and the longitudinal support plates 23 are installed in the square slots, with the longitudinal fixing rods 24 overlapping in the locking slots. Thus, the load can be transferred to the closed plates 211 through the peripheral support plates 212. The closed plates 211 are complete steel structures without slots or holes, and have a strong load-bearing capacity, which helps to ensure the safety of the rectangular frame 21.

[0051] This embodiment also provides a site isolation method, combined with Figures 1 to 2 The above-mentioned livestock-proof bridge is adopted, and the following steps are included:

[0052] S1: Set up a fence structure 4 around the construction site or the traffic road, and reserve an entrance 5 at the connection between the construction site and the rural road or the connection between the traffic road and the rural road.

[0053] S2: Excavate a flat-bottomed pit 6 at the junction of the rural road and the construction site or at the junction of the rural road and the traffic road, and set the livestock-proof bridge in the flat-bottomed pit 6 so that the bottom of the two support platforms 1 are in contact with the flat-bottomed pit 6. The two guardrails 3 are connected to the enclosure structure 4 on both sides of the entrance 5, and the bridge plate frame 2 is flush with the rural road.

[0054] The site isolation method in this embodiment combines the conventional traffic scheme of setting up open entrances and exits and operating in an unmanned manner with the above-mentioned livestock-proof bridge, which not only reduces the long-term management cost, but also has a good blocking effect on large livestock.

[0055] Preferably, in this embodiment, the specific steps for setting up the livestock-proof bridge in the flat-bottomed pit 6 in step S2 are as follows:

[0056] Step 1: Along the extension direction of the rural road, set up two support platforms 1 at parallel intervals at both ends of the flat-bottomed pit 6;

[0057] Step 2: Construct the rectangular frame 21, the horizontal support tube 22, the vertical support plate 23, and the vertical fixing rod 24;

[0058] Step 3: Install multiple parallel and spaced longitudinal support plates 23 and multiple parallel and spaced transverse support pipes 22 perpendicularly and staggeredly. After all the transverse support pipes 22 are neatly arranged on the longitudinal support plates 23, insert the longitudinal fixing rods 24. Then, move the transverse support pipes 22, longitudinal support plates 23 and longitudinal fixing rods 24 connected as a whole into the rectangular frame 21 and fix them to form the bridge plate frame 2, and make the bridge plate frame 2 flush with the rural road.

[0059] Step 4: Place two guardrails 3 parallel to each other on both sides of the bridge plate frame 2, and connect the two guardrails 3 to the enclosure structures 4 on both sides of the entrance 5 respectively.

[0060] Preferably, in step S1, the enclosure structure 4 is a construction site or traffic road guardrail, wire mesh, wall, or hedge. Since road guardrails, wire mesh, walls, or hedges can all achieve the purpose of enclosing the construction site, the specific selection of the enclosure structure 4 can be flexibly determined according to the actual site conditions.

[0061] Preferably, in step S2, the height difference between the bridge plate frame 2 and the flat-bottomed pit 6 is 18-22cm. At this height, even if the hooves of large livestock sink in, it will not cause injury, but will only hinder the movement of large livestock toward the construction site or traffic road.

[0062] Specifically, in this embodiment, in step S2, the height difference between the bridge plate frame 2 and the flat-bottomed pit 6 is 20cm.

[0063] Preferably, in step S2, the width of the bridge frame 2 is the same as the width of the rural road to ensure that the rural road will not experience traffic congestion due to the installation of the livestock-proof bridge.

[0064] In summary, this invention, in addition to employing conventional sealing measures, primarily utilizes livestock-proof bridges for barrier purposes. Due to its unique structural design, it effectively blocks large livestock without affecting the normal passage of pedestrians and small vehicles at the connection between the isolated area and rural roads. Furthermore, the livestock-proof bridge has a simple structure, is easy to install and disassemble, and can be used permanently or reused, effectively reducing long-term operating costs. Moreover, this invention is also applicable to other large-scale engineering and technical fields such as municipal engineering and transportation.

[0065] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
