Description

Technical Field

[0001] This application relates to a field, and in particular to a modular temporary road. Background Technology

[0002] Currently, temporary roads at construction sites need to meet the requirements of civilized construction. The site requires the use of reinforced concrete or extensive steel plate laying for temporary road surfaces. Thin concrete pavements are prone to damage due to heavy vehicle traffic or ground contact; therefore, pavements with sufficient thickness and reinforced with steel mesh are necessary to ensure normal operation of the temporary pavement for approximately three years. However, if the site is small, temporary road rerouting is extremely inconvenient, and after completion and handover, there will be significant issues with concrete pavement removal and waste disposal.

[0003] Chinese invention patent CN104631274A discloses a temporary road paving process, comprising the following steps: Step 1, laying a subbase layer, selecting crushed stone with a particle size of less than 150mm according to the required amount, and laying the crushed stone on the selected compacted road surface to form a crushed stone layer, and using a roller to compact the crushed stone layer until the crushed stone in the crushed stone layer is no longer loose; Step 2, laying a surface layer, selecting fine crushed stone with a particle size of 5-10mm according to the required amount, mixing the fine crushed stone with dry soil, sprinkling water while mixing, until the dry soil becomes clay and binds with the fine crushed stone to form a mud-bound crushed stone layer, laying the mud-bound crushed stone layer on the base layer, leveling it, and using a roller to compact it until there are no obvious wheel tracks on the surface of the mud-bound crushed stone layer; Step 3, laying a wear-resistant layer.

[0004] The aforementioned technologies have the following drawbacks: using crushed stone and clay to pave temporary roads makes recycling difficult after construction, makes them unusable for reuse, and results in high costs. Utility Model Content

[0005] To facilitate the recycling and reuse of temporary roads, this application provides an assembled temporary road.

[0006] This application provides a modular temporary road using the following technical solution:

[0007] A modular temporary road includes slabs, adjacent slabs abutting together, and drainage and ventilation holes provided on the slabs, with a plurality of drainage and ventilation holes arranged in an alternating pattern.

[0008] A first fixing component, disposed at the edge of the plate, is used to fix two adjacent plates together; and...

[0009] The second fixing component is located at the corner of the plate and is used to fix four adjacent plates together.

[0010] By adopting the above technical solution, the slab, as an independent basic module, constitutes the basic unit of the temporary road. After adjacent slabs come together, the first fixing component at the edge plays a role, mechanically fixing the two slabs tightly to form a lateral connection. At the corner where the four slabs meet, the second fixing component penetrates through the four adjacent slabs to achieve a stable connection at the node and form a longitudinal constraint. The two fixing components work together to make the dispersed slabs form an integrated road structure. The staggered drainage and ventilation holes on the slabs can quickly drain the water on the road surface, prevent the connection between the slab and the foundation from loosening due to rainwater soaking, and avoid additional stress on the fixing components due to air pressure difference. At the same time, the good drainage and ventilation performance can reduce the corrosion and aging of the slab and fixing components caused by the humid environment, ensuring their reusability after disassembly.

[0011] Preferably, the drainage and venting holes are strip-shaped.

[0012] By adopting the above technical solution, the strip-shaped hole has a large length-to-diameter ratio, which can provide a larger water passage compared with the circular or square hole. Under the same opening ratio, the strip-shaped hole has a higher drainage efficiency.

[0013] Preferably, the first fixing component includes an upper support rod, a lower support rod, and a first bolt. A first connecting hole is provided at the edge of the plate. The lower support rod abuts against the bottom of the plate, and the upper support rod abuts against the top of the plate. A first through hole is provided at both ends of the upper support rod, and a first screw hole is provided at both ends of the lower support rod. The first bolt passes through the first through hole and is threaded into the first screw hole. The first bolt passes through the first connecting hole.

[0014] By adopting the above technical solution, the upper support rod and the lower support rod abut from the top and bottom of the plate respectively, forming a bidirectional clamping force. When the first bolt is tightened, the upper support rod and the lower support rod tightly press and fix the two adjacent plates together through the axial tension of the first bolt. The upper support rod and the lower support rod increase the contact area with the plate. Under the action of vehicle load, the pressure can be evenly distributed to more areas of the plate, avoiding local stress concentration that could lead to plate damage.

[0015] Preferably, the upper support rod has a first countersunk groove at both ends, and the nut of the first bolt is located in the first countersunk groove.

[0016] By adopting the above technical solution, in traditional bolted connections, the nut protruding from the road surface can easily cause bumps when vehicles run over it, or even scratch the tires. The countersunk groove design allows the nut to be fully embedded in the upper support rod, flush with the top surface of the plate, improving the overall flatness of the road surface, significantly improving the comfort of passage, and at the same time preventing the nut from being deformed or falling off by being run over.

[0017] Preferably, the second fixing component includes an upper bracket, a lower bracket, and a second bolt. A second connecting hole is provided at the corner of the plate. The lower bracket abuts against the bottom of the plate, and the upper bracket abuts against the top of the plate. A second through hole is provided at the corner of the upper bracket, and a second screw hole is provided at the corner of the lower bracket. The second bolt passes through the second through hole and is threaded into the second screw hole. The second bolt passes through the second connecting hole.

[0018] By adopting the above technical solution, the upper and lower supports clamp the corners of the four intersecting plates from the top and bottom of the plate, respectively. The second bolt passes through the second through hole of the upper support, the second connecting hole of the plate, and the second screw hole of the lower support and is tightened to form a three-dimensional fastening structure. This effectively prevents the road from separating and warping under the lateral forces generated by vehicles turning and braking. The upper and lower supports increase the contact area with the corners of the plate, and evenly distribute the concentrated stress generated by vehicle loads to the four plates, avoiding local cracking due to excessive stress and extending the overall service life of the road.

[0019] Preferably, a second countersunk groove is provided at the corner of the upper bracket, and the nut of the second bolt is located in the second countersunk groove.

[0020] By adopting the above technical solution, the second countersunk groove makes the second bolt nut flush with the top surface of the upper bracket, avoiding the nut from protruding and forming a road obstacle. When heavy vehicles run over it, they will not cause bumps or tire jumps due to collision with the nut. Pedestrians can also pass more smoothly, reducing the risk of tripping and ensuring traffic safety.

[0021] Preferably, the bottom of the plate is provided with reinforcing ribs.

[0022] By adopting the above technical solution, the reinforcing ribs are distributed in a grid or strip shape at the bottom of the plate, which disperses the pressure generated by vehicle loads to a larger area. Under the action of lateral force or impact force generated by vehicle braking, turning, etc., the reinforcing ribs can limit the twisting and deformation of the plate.

[0023] Preferably, the reinforcing rib is provided with drainage holes.

[0024] By adopting the above technical solution, the drainage holes on the bottom reinforcing ribs of the slab are connected to the drainage and ventilation holes on the surface of the slab, forming a three-dimensional drainage channel. Rainwater can not only quickly infiltrate through the holes on the surface of the slab, but also be quickly discharged through the drainage holes of the reinforcing ribs, effectively preventing the roadbed from being soaked and softened for a long time.

[0025] In summary, this application includes the following beneficial technical effects: the prefabricated temporary road, through detachable fixing components, can be quickly disassembled into independent panels and fixing components after construction. The recycled panels and components can be reused for the construction of new temporary roads after simple cleaning and maintenance, which greatly improves the material utilization rate.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This utility model provides an assembled temporary road, the structure of which is as follows: Figure 1 - Figure 4 As shown, it includes a plate body 1, a first fixing component 2, and a second fixing component 3.

[0034] The adjacent plates 1 abut together, and the plates 1 are provided with drainage and ventilation holes 11, and the plurality of drainage and ventilation holes 11 are arranged in an alternating manner.

[0035] The first fixing component 2 is located at the edge of the plate 1, and the first fixing component 2 is used to fix two adjacent plates 1 together.

[0036] The second fixing component 3 is located at the corner of the plate 1, and the second fixing component 3 is used to fix four adjacent plates 1 together.

[0037] In use, the slab 1 serves as an independent basic module, forming the basic unit of the temporary road. After adjacent slabs 1 come together, the first fixing component 2 at the edge plays its role, mechanically fixing the two slabs 1 tightly to form a lateral connection. At the corner where the four slabs 1 intersect, the second fixing component 3 penetrates through the four adjacent slabs 1, achieving a stable connection at the node and forming a longitudinal constraint. The two fixing components work together to make the dispersed slabs 1 form an integrated road structure. The staggered drainage and ventilation holes 11 on the slab 1 can quickly drain the water on the road surface, preventing the connection between the slab 1 and the foundation from loosening due to rainwater soaking, and avoiding additional stress on the fixing components due to air pressure difference. At the same time, the good drainage and ventilation performance can reduce the corrosion and aging of the slab 1 and the fixing components caused by the humid environment, ensuring their reusability after disassembly.

[0038] In this invention, the assembled temporary road uses detachable fixing components. After construction, it can be quickly disassembled into independent panels 1 and fixing components. After simple cleaning and maintenance, the recycled panels 1 and components can be reused to build new temporary roads, greatly improving material utilization.

[0039] To improve the drainage efficiency of plate 1, please refer to... Figure 1 In a preferred embodiment, the drainage and venting hole 11 is strip-shaped.

[0040] When in use, the strip-shaped hole has a large length-to-diameter ratio, which provides a larger water passage compared to round or square holes. Under the same opening ratio, the strip-shaped hole has a higher drainage efficiency.

[0041] To connect the edges of plate 1 together, please refer to... Figure 3 In a preferred embodiment, the first fixing component 2 includes an upper support rod 21, a lower support rod 22, and a first bolt 23. A first connecting hole 24 is provided at the edge of the plate 1. The lower support rod 22 abuts against the bottom of the plate 1, and the upper support rod 21 abuts against the top of the plate 1. The upper support rod 21 has first through holes 25 at both ends, and the lower support rod 22 has first screw holes 26 at both ends. The first bolt 23 passes through the first through hole 25, is threaded into the first screw hole 26, and passes through the first connecting hole 24.

[0042] During use, the upper support rod 21 and the lower support rod 22 abut against the top and bottom of the plate 1 respectively, forming a bidirectional clamping force. When the first bolt 23 is tightened, the upper support rod 21 and the lower support rod 22 tightly press and fix the two adjacent plates 1 together through the axial tension of the first bolt 23. The upper support rod 21 and the lower support rod 22 increase the contact area with the plate 1, and under the action of vehicle load, the pressure can be evenly distributed to more areas of the plate 1, avoiding local stress concentration that could lead to damage to the plate 1.

[0043] To improve road surface smoothness, please refer to... Figure 2 In a preferred embodiment, the upper support rod 21 has first countersunk grooves 27 at both ends, and the nut of the first bolt 23 is located in the first countersunk grooves 27.

[0044] In traditional bolted connections, the nuts protrude from the road surface, which can cause bumps when vehicles run over them and even scratch the tires. The countersunk groove design allows the nuts to be fully embedded in the upper support rod 21 and flush with the top surface of the plate 1, improving the overall flatness of the road surface and significantly improving the comfort of driving. At the same time, it prevents the nuts from being deformed or falling off by being run over.

[0045] To connect the corner points of adjacent plates 1, please refer to... Figure 4 In a preferred embodiment, the second fixing component 3 includes an upper bracket 31, a lower bracket 32, and a second bolt 33. A second connecting hole 34 is provided at the corner of the plate 1. The lower bracket 32 ​​abuts against the bottom of the plate 1, and the upper bracket 31 abuts against the top of the plate 1. A second through hole 35 is provided at the corner of the upper bracket 31, and a second screw hole 36 is provided at the corner of the lower bracket 32. The second bolt 33 passes through the second through hole 35 and is threaded into the second screw hole 36. The second bolt 33 passes through the second connecting hole 34.

[0046] In use, the upper bracket 31 and the lower bracket 32 ​​clamp the corners of the four intersecting plates 1 from the top and bottom of the plate 1, respectively. The second bolt 33 passes through the second through hole 35 of the upper bracket 31, the second connecting hole 34 of the plate 1, and the second screw hole 36 of the lower bracket 32 ​​and is tightened to form a three-dimensional fastening structure. This effectively prevents the road from separating and warping under the lateral forces generated by vehicles turning or braking. The upper bracket 31 and the lower bracket 32 ​​increase the contact area with the corners of the plate 1, and evenly distribute the concentrated stress generated by vehicle loads to the four plates 1, avoiding local cracking of the plate 1 due to excessive stress and extending the overall service life of the road.

[0047] To further improve the smoothness of the road surface, please refer to... Figure 1 In a preferred embodiment, a second countersunk groove 37 is provided at the corner of the upper bracket 31, and the nut of the second bolt 33 is located in the second countersunk groove 37.

[0048] When in use, the second countersunk groove 37 makes the second bolt 33 nut flush with the top surface of the upper bracket 31, preventing the nut from protruding and forming a road obstacle. When heavy vehicles run over it, they will not cause bumps or tire jumps due to collision with the nut. Pedestrians can also pass more smoothly, reducing the risk of tripping and ensuring traffic safety.

[0049] To improve the strength of plate 1, please refer to... Figure 2In a preferred embodiment, the bottom of the plate 1 is provided with reinforcing ribs 12.

[0050] When in use, the reinforcing ribs 12 are distributed in a grid or strip shape at the bottom of the plate 1, dispersing the pressure generated by vehicle loads to a larger area. Under the action of lateral forces or impact forces generated by sudden braking or turning of the vehicle, the reinforcing ribs 12 can limit the twisting and deformation of the plate 1.

[0051] To improve the drainage efficiency of plate 1, please refer to... Figure 2 In a preferred embodiment, the reinforcing rib 12 is provided with a drainage hole 13.

[0052] During use, the drainage holes 13 on the bottom reinforcing ribs 12 of the slab 1 are connected vertically with the drainage and ventilation holes 11 on the surface of the slab 1, forming a three-dimensional drainage channel. Rainwater can not only seep down quickly through the holes on the surface of the slab 1, but also be quickly discharged through the drainage holes 13 of the reinforcing ribs 12, effectively preventing the roadbed from being soaked and softened for a long time.

[0053] The implementation principle of a modular temporary road according to an embodiment of this application is as follows: the slab 1 serves as an independent basic module, constituting the basic unit of the temporary road. After adjacent slabs 1 come into contact, the first fixing component 2 at the edge plays a role, mechanically fixing the two slabs 1 tightly to form a lateral connection. At the corner where the four slabs 1 intersect, the second fixing component 3 penetrates through the four adjacent slabs 1, realizing a stable connection at the node and forming a longitudinal constraint. The two fixing components work together to make the dispersed slabs 1 form an integral road structure. The drainage and ventilation holes 11 arranged in a staggered manner on the slabs 1 can quickly drain the water on the road surface, prevent the connection between the slabs 1 and the foundation from loosening due to rainwater soaking, and avoid additional stress on the fixing components due to air pressure difference. At the same time, the good drainage and ventilation performance can reduce the corrosion and aging of the slabs 1 and fixing components caused by the humid environment, ensuring their reusability after disassembly.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
