Description

Technical Field

[0001] This application relates to the technical field of road engineering, and particularly relates to a prefabricated assembled road structure. Background Art

[0002] For a prefabricated assembled road, road blocks are prefabricated in a factory and then transported to the construction site after the roadbed is leveled; then, through a hoisting device, the road blocks are evenly laid along the road extension direction, and the road blocks are fixed on the roadbed by their own gravity, which is convenient for laying and also convenient for maintenance and replacement when the road blocks are damaged.

[0003] When it rains, rainwater falls on the top of the road blocks and then flows along the surface of the road blocks. Since there are gaps between adjacent road blocks, most of the rainwater flows into the gaps; when the rainwater flows to the roadbed, the rainwater begins to penetrate into the underground soil, thereby realizing rainwater drainage. However, when the rain is heavy, the amount of rainwater flowing into the gaps between adjacent road blocks greatly increases. When the soil fails to penetrate and drain the rainwater in time, water accumulates on the roadbed surface, and as the amount of rainwater increases, the accumulated water gradually spreads around, easily washing out the soil under the road blocks, causing problems such as settlement and inclination of the road blocks, and affecting the use effect of the road. Summary of the Invention

[0004] In order to reduce the possibility of soil rainwater being washed away from the bottom of the road when it rains, this application provides a prefabricated assembled road structure.

[0005] This application provides a prefabricated assembled road structure, adopting the following technical solution:

[0006] A prefabricated assembled road structure,

[0007] comprising

[0008] road plates, which are evenly laid along the road extension direction, and adjacent road plates are in contact with each other. Catch basins are formed at the top of the road plates and are connected in a staggered manner;

[0009] The road plates include connecting strips, and the connecting strips include long connecting strips and short connecting strips. The long connecting strips and the short connecting strips are arranged at intervals at the edge position of the top of the road plates. The short connecting strips are located between adjacent long connecting strips, and the connecting strips extend along the edge trajectory of the road plates;

[0010] sealing strips, including long sealing strips and short sealing strips. The long sealing strips are formed with long grooves, and adjacent long connecting strips of adjacent road plates are inserted into the long grooves; the short sealing strips are formed with short grooves, and adjacent short connecting strips of adjacent road plates are inserted into the short grooves. The long sealing strips and the short sealing strips are in contact with each other, and the long sealing strips in the same length direction are in contact with each other;

[0011] A drain pipe is laid under the road slab. The road slab further includes a water inlet pipe, and the water inlet pipe penetrates through the road slab and is communicated with the water collecting tank.

[0012] By adopting the above technical solution, when it rains, rainwater falls on the surface of the road slab and the surface of the sealing strip, and then the rainwater flows along the surface of the road slab and the surface of the sealing strip until it flows into the water collecting tank. Then the rainwater flows into the water inlet pipe along the water collecting tank, then flows into the drain pipe through the water inlet pipe, and finally is discharged through the drain pipe; the rainwater is discharged through the drain pipe, reducing the amount of rainwater flowing to the bottom of the road slab. At the same time, the gap between adjacent road slabs is sealed by the sealing strip, reducing the possibility of rainwater flowing to the bottom of the road slab through the gap between adjacent road slabs, enabling the rainwater at the bottom of the road slab to be discharged in time through soil infiltration, and reducing the possibility of rainwater scouring and carrying away the soil when flowing around due to untimely discharge.

[0013] Optionally, a receiving groove communicated with the water collecting tank is formed at the top of the road slab, and the long sealing strip and the short sealing strip are located in the receiving groove.

[0014] By adopting the above technical solution, the sealing strip is located in the receiving groove, which is beneficial to conceal the sealing strip.

[0015] Optionally, the short sealing strip includes a fixing block abutting against the long sealing strip, and a fixing screw is inserted through the fixing block, and the fixing screw is threadedly connected to the long sealing strip;

[0016] The long sealing strip is formed with a connecting groove, and a fixing bolt located in the connecting groove is inserted through the long sealing strip, and the fixing bolt is threadedly connected with a fixing nut.

[0017] By adopting the above technical solution, the short sealing strip and the long sealing strip are fixedly connected to each other, and the long sealing strips on the same straight line are fixedly connected to each other, reducing the possibility of the long sealing strip and the short sealing strip detaching from the receiving groove.

[0018] Optionally, the top parts of the side walls on the opposite sides in the length direction of the connecting strip respectively include retaining strips, and the sealing strips are respectively slidably inserted with limiting strips, and the limiting strips correspond to the retaining strips one by one;

[0019] The long sealing strip and the short sealing strip are respectively provided with a control assembly, and the control assembly controls the limiting strip to move to directly below the retaining strip, or drives the limiting strip to be misaligned with the retaining strip.

[0020] By adopting the above technical solution, the retaining strip can limit the limiting strip, further reducing the possibility of the long sealing strip and the short sealing strip detaching from the receiving groove.

[0021] Optionally, the control assembly includes

[0022] Control columns, the control columns corresponding to and rotatably connected to the limiting strips one by one, a threaded section being provided on the outer peripheral side of the control columns and close to the limiting strips, and the threaded section being threadedly connected to the sealing strips;

[0023] A control spring, sleeved on the outer peripheral side of the control column, with one end abutted against the limiting strip and the other end abutted against the sealing strip.

[0024] By adopting the above technical solution, when the control spring pushes the limiting strip to move to directly below the blocking strip so that the sealing strip disengages from the receiving groove, the blocking strip can limit the limiting strip, thereby reducing the possibility of the sealing strip disengaging from the receiving groove.

[0025] Optionally, there is a gap between the limiting strip and the blocking strip.

[0026] By adopting the above technical solution, a certain buffer space is provided for the sealing strip, so that when the road plate settles, the force exerted on the sealing strip due to the settlement of the road plate is reduced.

[0027] Optionally, the road plate is inclined to form a guiding surface, the guiding surface is located at the bottom of the water collecting tank, and the guiding surface guides rainwater towards the water inlet pipe.

[0028] By adopting the above technical solution, it is used to guide rainwater to flow towards the water inlet pipe and improve the flow rate of rainwater in the water collecting tank.

[0029] Optionally, the road plate is provided with fixing columns, and the fixing columns are inserted into the ground.

[0030] By adopting the above technical solution, the movement of the road plate in the horizontal direction and its separation from the ground are further restricted.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. Rainwater can enter the water collecting tank and be discharged through the drain pipe, and the gap between adjacent road plates is blocked by the sealing strip, greatly reducing the amount of rainwater flowing to the bottom of the road plate and reducing the possibility that the rainwater at the bottom of the road plate is not discharged in time and causes the rainwater to flow around and wash away the soil;

[0033] 2. The blocking strip restricts the limiting strip, reducing the possibility of the sealing strip disengaging from the receiving groove. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Description of the Embodiments

[0043] The following further describes the present application in detail Figures 1-8 in conjunction with the accompanying

[0044] The embodiments of the present application disclose a prefabricated and assembled road structure.

[0045] Embodiment 1

[0046] Referring to Figure 1 , the prefabricated and assembled road structure includes a road slab 1, a sealing strip 3, and a drain pipe 4.

[0047] Among them, in this embodiment, the top end face of the road slab 1 is a rectangular structure. In other embodiments, the top end face of the road slab 1 can also be a square structure. The road slab 1 is formed by casting reinforced concrete, and the road slab 1 has a certain thickness, so that the weight of the formed road slab 1 is relatively heavy, and it can be fixed on the road surface by its own weight. When the road slab 1 is laid, it is hoisted to the road surface by a hoisting device, and the road slabs 1 are laid at equal intervals along the extension direction of the road, and adjacent road slabs 1 abut against each other. Drainage ditches can be opened on both sides of the road composed of the road slabs 1 along the extension direction of the road for drainage, and reduce the possibility that the rainwater falling around the road flows to the bottom of the road slab 1 when it rains.

[0048] See Figure 2 , in order to improve the installation stability of the road slab 1, the road slab 1 is provided with fixing columns 8. The fixing columns 8 are fixed to the bottom of the road slab 1, and the bottom parts of the fixing columns 8 are inserted into the soil, which can limit the road slab 1 from moving upward away from the ground and at the same time limit the road slab 1 from moving horizontally.

[0049] There are multiple drain pipes 4 and they are buried in the soil under the road surface. The drain pipes 4 extend along the extension direction of the road, and each row of road slabs 1 along the extension direction of the road corresponds to one drain pipe 4 respectively. The drain pipes 4 are connected to the municipal rain and sewage pipes.

[0050] The top of the drain pipe 4 is fixedly connected with a water inlet pipe 41, and each water inlet pipe 41 corresponds to a road slab 1 respectively. An installation hole 13 is opened at the middle position of the top of the road slab 1, and the water inlet pipe 41 is installed in the installation hole 13. The top end face of the water inlet pipe 41 is located below the top end face of the road slab 1.

[0051] A water collecting groove 11 is opened at the top of the road slab 1. The water collecting groove 11 is communicated with the installation hole 13. There are multiple water collecting grooves 11 and they are evenly spaced along the circumferential direction with the installation hole 13 as the center. The bottom wall of the water collecting groove 11 is located above the top end face of the water inlet pipe 41. When it rains, rainwater can enter the water collecting groove 11, then flow into the water inlet pipe 41 along the water collecting groove 11, and finally enter the drain pipe 4 through the water inlet pipe 41, and then be discharged into the municipal rain and sewage pipes. At this time, the amount of rainwater flowing to the top of the road slab 1 is greatly reduced, which is beneficial to reducing the pressure of soil drainage and reducing the possibility that the soil is carried away when the rainwater is not discharged in time and flows everywhere.

[0052] See Figure 2 And Figure 3, To further reduce the amount of rainwater on the top of the road slab 1, a guiding surface 111 is provided on the road slab 1. The guiding surface 111 is located on the bottom wall of the water collecting tank 11 and is inclined. After the rainwater flows into the water collecting tank 11, it flows along the guiding surface 111 towards the water inlet pipe 41, accelerating the flow rate of the rainwater and enhancing the discharge speed of the rainwater in the water inlet tank, enabling more rainwater to flow into the water inlet pipe 41 through the water collecting tank 11.

[0053] A receiving groove 12 is provided at the top of the road slab 1. The receiving groove 12 is located at the edge position of the road slab 1 and forms a "mouth" - shaped extension trajectory along the extension direction of the edge of the road slab 1. The receiving groove 12 is communicated with the water collecting tank 11, and the bottom wall of the receiving groove 12 is above the higher - side of the upper and lower height of the guiding surface 111. The rainwater in the receiving groove 12 can flow into the water collecting tank 11.

[0054] See Figure 4 And Figure 5 , A connecting strip 2 is fixedly connected to the road slab 1. The connecting strip 2 is located in the receiving groove 12. The connecting strip 2 includes two long connecting strips 21 and two short connecting strips 22. The long connecting strips 21 and the short connecting strips 22 are perpendicular to each other and arranged at intervals. The short connecting strips 22 are located between the two long connecting strips 21 and there is a spacing between the long connecting strips 21 and the short connecting strips 22. At the same time, the length direction of the long connecting strip 21 is parallel to the length direction of the road slab 1, and the length direction of the short connecting strip 22 is parallel to the width direction of the road slab 1.

[0055] See Figure 4 , After the road slabs 1 are laid, the adjacent short connecting strips 22 between adjacent road slabs 1 are in a parallel state, the adjacent long connecting strips 21 between adjacent road slabs 1 along the road extension direction are on the same straight line, and the adjacent long connecting strips 21 of adjacent road slabs 1 in the same row are parallel to each other.

[0056] See Figure 1 And Figure 2 , The sealing strip 3 includes a long sealing strip 31 and a short sealing strip 32. The long sealing strip 31 corresponds to the long connecting strip 21 one - to - one and has the same length. The short sealing strip 32 corresponds to the short connecting strip 22 one - to - one and has the same length. The long sealing strip 31 is provided with a long groove 311 along its length direction, and the short sealing strip 32 is provided with a short groove 321 along its length direction (the short groove 321 is marked in Figure 3 ).

[0057] See Figure 1 And Figure 3, during installation, the parallel and adjacent long connecting strips 21 are snapped into the same long groove 311, and the parallel and adjacent short connecting strips 22 are snapped into the same short groove 321. At this time, the long sealing strip 31 and the short sealing strip 32 are in contact with each other and are respectively located in the receiving groove 12. The bottoms of the long sealing strip 31 and the short sealing strip 32 respectively abut against the bottom wall of the receiving groove 12. The gap on one long side of the adjacent road plates 1 is sealed by the long sealing strip 31, and the gap on one short side of the adjacent road plates 1 is sealed by the short sealing strip 32. When it rains, rainwater falls on the top of the sealing strip 3, then flows into the receiving groove 12 along the surface of the sealing strip 3, and then flows from the receiving groove 12 into the water collecting groove 11, reducing the possibility of rainwater flowing to the bottom of the road plate 1 through the gap between the adjacent road plates 1.

[0058] See Figure 4 and Figure 5 , in order to improve the installation stability of the long sealing strip 31 and the short sealing strip 32, a fixing block 322 is fixedly connected to the side wall of the short sealing strip 32, and the fixing block 322 abuts against the adjacent long sealing strip 31. A fixing screw 323 is passed through the fixing block 322, and the fixing screw 323 is threadedly connected to the long sealing strip 31, so that the long sealing strip 31 and the short sealing strip 32 are fixedly connected. A connecting groove 312 is formed at the top of the long sealing strip 31. The connecting grooves 312 of the long sealing strips 31 on the same straight line are arranged adjacent to each other, and a fixing bolt 313 is passed through the long sealing strip 31. The bolt head of the fixing bolt 313 is located in one of the connecting grooves 312, and the screw rod extends into the other connecting groove 312. A fixing nut 314 is threadedly connected to the fixing bolt 313, and the fixing nut 314 is located in the other connecting groove 312, so that the fixing bolt 313 and the fixing nut 314 cooperate to fix two adjacent long sealing strips 31 on the same straight line. During installation, the connection and fixation of the long sealing strips 31 are realized through the cooperation of the fixing bolt 313 and the fixing nut 314, reducing the possibility of the long sealing strip 31 and the short sealing strip 32 disengaging upward from the receiving groove 12.

[0059] The implementation principle of a prefabricated assembled road structure in Embodiment 1 of the present application is as follows:

[0060] When it rains, rainwater falls on the top of the road plate 1 and the top of the sealing strip 3. Then the rainwater flows into the water collecting groove 11 along the surface of the road plate 1 and the surface of the sealing strip 3. Then the rainwater flows into the water inlet pipe 41 along the guiding surface 111, and finally is discharged into the municipal rain and sewage pipeline through the drain pipe 4, greatly reducing the possibility of rainwater flowing to the bottom of the road plate 1 through the gap between the adjacent road plates 1. After the amount of rainwater flowing to the bottom of the road plate 1 decreases, the ground soil can have sufficient time for rainwater drainage and infiltration, reducing the possibility of rainwater being discharged untimely and flushing the surrounding soil away from the bottom of the road plate 1.

[0061] Embodiment 2

[0062] SeeFigure 6 , the difference between the second embodiment and the first embodiment itself is that the connecting strip 2 is provided with a retaining strip 5, and the blocking strip 3 is provided with a limiting strip 6.

[0063] See Figure 7 , wherein the retaining strips 5 are arranged on two opposite sides in the length direction of the connecting strip 2, and the retaining strips 5 are located at the top position of the connecting strip 2, and the length direction of the retaining strips 5 is parallel to the length direction of the connecting strip 2.

[0064] See Figure 7 And Figure 8 , the limiting strips 6 correspond to the retaining strips 5 one by one. A limiting groove 14 is formed in the blocking strip 3, and the limiting strips 6 are located in the limiting groove 14. When the long connecting strip 21 is inserted into the long groove 311 and the short connecting strip 22 is inserted into the short groove 321, the limiting strip 6 is located below the retaining strip 5. The blocking strip 3 is provided with a control component 7 for controlling the position of the limiting strip 6. When the control component 7 controls the limiting strip 6 to move to directly below the retaining strip 5, the top of the limiting strip 6 can abut against the bottom of the retaining strip 5, restricting the blocking strip 3 from disengaging from the receiving groove 12.

[0065] The control component 7 includes a control column 71 and a control spring 72. The control columns 71 correspond to the limiting strips 6 one by one. One end of the control column 71 is rotatably connected to the middle position on the side of the limiting strip 6 facing away from the connecting strip 2. The blocking strip 3 is provided with a control hole 15 communicating with the limiting groove 14. A threaded section 711 is formed on the outer peripheral side of the control column 71, and the threaded section 711 is located near the limiting strip 6 and is threadedly connected to the hole wall of the control hole 15. The control spring 72 is sleeved on the outer peripheral side of the control column 71. One end of the control spring 72 abuts against the side of the limiting strip 6 facing away from the connecting strip 2, and the other end abuts against the groove wall on the side of the limiting groove 14 away from the groove opening.

[0066] See Figure 6 And Figure 8 , in the initial state, the threaded section 711 is threadedly connected to the hole wall of the control hole 15. At this time, the limiting strip 6 is located in the limiting groove 14, and the control spring 72 is in a compressed state. When the long connecting strip 21 is inserted into the long groove 311 and the short connecting strip 22 is inserted into the short groove 321, the control column 71 is rotated so that the threaded section 711 disengages from the control hole 15. At this time, the control spring 72 elastically releases and pushes the limiting strip 6 to abut against the side wall of the connecting strip 2. The limiting strip 6 is located directly below the retaining strip 5 and there is a gap between the limiting strip 6 and the retaining strip 5. When the ground subsides, the road plate 1 follows the ground to subside. At this time, there is a gap between the retaining strip 5 and the limiting strip 6, reducing the possibility that the blocking strip 3 deforms under the settlement force when the road plate 1 subsides.

[0067] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
