Description

Technical Field

[0001] The utility model relates to the field of assembled construction, in particular to a prefabricated shoulder and an assembled field road structure. Background Art

[0002] With the development of cities and towns, dirt roads next to cultivated land or cultivated fields are gradually replaced by hardened roads. At present, hardened roads in the fields are mainly made of multiple precast concrete slabs. For example, the Chinese patent with application number 2019105044278 discloses a prefabricated assembled concrete road, which includes a number of concrete road modules, each of which has a square tongue and groove at the four corners, and each corner forms a tongue and groove. There is a through hole between two adjacent tongues and grooves, and a concrete road module forms four through holes, including two transverse through holes and two longitudinal through holes. The concrete road module is used in conjunction with the transverse connecting shaft and the longitudinal connecting shaft. The above-mentioned assembled concrete road has no shoulders on both sides, and cannot form a barrier to the soil and groundwater on both sides of the road, so that the soil on both sides of the road can easily enter the hardened road.

[0003] To solve the above problems, Chinese patent application number 2021101277492 discloses a revolving assembled road system, which includes a temporary road plate, a first support and a second support supported below the left and right edges of the temporary road plate, a drainage ditch and an integrated pipe ditch. The top surfaces of the drainage ditch and the integrated pipe ditch are at the same height as the top surface of the temporary road plate. The lower end of the integrated pipe ditch is embedded in the foundation. The drainage ditch is composed of several sections of drainage ditch sections connected in sequence; the integrated pipe ditch includes several sections of integrated pipe ditch sections connected in sequence and pipeline supports arranged on the inner side of the integrated pipe ditch sections. Although the above-mentioned assembled road system can effectively solve the drainage problem, it is more troublesome to assemble, and the width after assembly is larger, which is not suitable for the setting of field paths. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a prefabricated shoulder and assembled field road structure to solve the problems of the existing assembled roads, which are complex in structure, inconvenient to assemble, and not suitable for field roads.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A prefabricated shoulder includes a plurality of hard support components with detachable side ends, the hard support components are composed of a first support block and a second support block connected to each other at the side ends, the first support block is in an inverted T-shape, and the two connecting sides of its lower end extend outward to form a first connection part; the second support block is in a T-shape, and the two connecting sides of its upper end extend outward to form a second connection part that matches the first connection part; a road panel assembly groove is provided on the inner side of the upper ends of the first support block and the second support block, and a plurality of drainage holes are provided at intervals at the lower ends of the first support block and the second support block along the width direction thereof. In this way, when assembling the shoulder, it is only necessary to assemble the plurality of first support blocks and the second support blocks together to form the shoulder, the first support blocks and the second support blocks have simple structures, and after assembly, they can form protection on the sides to prevent mud from entering the road surface plate. The upper ends and lower ends of the first and second support blocks are extended outward so that they can overlap each other and the overlapped parts are tightly matched; the road panel assembly grooves provided on the inner sides of the first and second support blocks can support the road panel and are connected with the side ends of the road panel, making the road panel assembly convenient. At the same time, the drainage holes provided on the first and second support blocks can drain the accumulated water in the soil layer.

[0007] Further, a plurality of biological passages are also provided at the upper ends of the first support block and the second support block. In this way, after the biological passages are provided, it is convenient for small animals in the field to pass through, and small animals in the field are prevented from being accidentally injured when crossing the road.

[0008] Furthermore, the first support block and the second support block are both precast concrete blocks with built-in steel mesh. In this way, the built-in steel mesh can effectively increase its structural strength, and the precast concrete block also has the advantages of high strength and low production cost.

[0009] Furthermore, a mounting groove is provided at the upper end of the two first connection parts of each first support block along the width direction of the first support block; and a protrusion matching the mounting groove is provided at the lower end of the two second connection parts of each second support block. In this way, after the mounting groove and the protrusion are provided, a mortise and tenon connection can be formed, so that the connection structure between the first support block and the second support block is tight and not easy to fall due to lateral pressure.

[0010] Furthermore, an assembly groove is provided along the width direction of the upper end of the first connection part on the left side of each first support block and the lower end of the second connection part on the left side of each second support block; a protrusion is provided at the upper end of the first connection part on the right side of each first support block and the lower end of the second connection part on the right side of each second support block, and the assembly groove on the first support block is provided correspondingly to the protrusion on the second support block, and the protrusion on the first support block is provided correspondingly to the assembly groove on the second support block. In this way, the assembly groove and the protrusion are respectively located on both sides of the connection end of the first support block and the second support block, so that the assembly groove on the first support block and the protrusion on the second support block are correspondingly buckled, and the protrusion on the first support block and the assembly groove on the second support block correspond to the fastener, and the first support block and the second support block can also be connected and fixed together through the mortise and tenon structure.

[0011] Furthermore, a water hole is provided at the lower end of the first support block and the second support block along the length direction thereof, and the water hole is connected to each drainage hole. In this way, after the water hole is provided, the water flowing along the connection seam can be introduced into the drainage hole through the water hole and then discharged, and the water can be discharged more thoroughly.

[0012] Furthermore, a plurality of grooves are provided at intervals on the lower end surfaces of each of the first support block and the second support block, so that the provided grooves can fit the ground to form a good grip, so that the first support block and the second support block can stand firmly on the ground.

[0013] A prefabricated field road structure comprises a compacted soil layer and at least one row of prefabricated road panels laid on the compacted soil layer, wherein the middle portion of the compacted soil layer bulges upward, and shoulder assembly positions are formed on both sides; the prefabricated road panels are laid on the bulge of the compacted soil layer, and the outer edges of the prefabricated road panels near the left and right sides of the bulge extend out of the bulge; a plurality of hard support components are laid on the two shoulder assembly positions, whose side ends are connected to each other and the inner sides of the upper ends are connected to the outer edges of the road panels; the hard support components are as described above, and the upper end faces of the hard support components are higher than the upper end faces of the prefabricated road panels or are flush with the upper end faces of the prefabricated road panels; a plurality of biological passage holes are also provided on each prefabricated road panel, and the two ends of the biological passage holes correspond to and are connected with the biological channels of the corresponding side hard support components. In this way, when installing the field road, it is only necessary to tamp the plain soil, and then lay the prefabricated road panel and the shoulders on both sides of the walking path formed by the road panel (i.e., the support formed by assembling and connecting a plurality of hard support components connected end to end). There are few assembly parts, and the assembly between the prefabricated road panel and the first support block and the second support block, as well as the assembly connection between each first support block and the second support block are relatively convenient, and the overall road structure is simple. After assembly, the prefabricated road panel forms a hardened road surface for walking after paving, and the first support block and the second support block installed on both sides form shoulders, which can block the soil on both sides of the hardened road surface. Of course, specifically, the bulge of the plain soil tamping layer can be directly raised on the field land, so that the hardened road surface is higher than the cultivated land, and a soil barrier can be formed. After the through holes set on the first support block, the second support block and the prefabricated road panel are connected, an animal passage connecting two adjacent fields can be formed, so that the passages of small creatures and people are separated, thereby avoiding the phenomenon of animals being trampled, and well ensuring the biological system between fields.

[0014] Furthermore, the prefabricated road panels are arranged in two rows, and a plurality of middle support blocks whose upper ends are connected to the two prefabricated road panels are embedded in the middle of the compacted soil layer at the junction of the two rows of prefabricated road panels; and a lap step surface matching the road panel assembly groove is arranged on the left and right sides of each prefabricated road panel. In this way, if some small machinery needs to pass through and the road surface is set to a wider width, two or more rows of prefabricated road panels can be laid. And the middle support blocks are arranged at the junction of the prefabricated road panels, which can form a good support for each prefabricated road panel, making the road surface structure more stable.

[0015] Furthermore, a buckle block extending downward is provided on the outer side of the overlapping step surface of each prefabricated road panel, and a slot matching with the buckle blocks of the two prefabricated road panels is provided in the middle of the upper end surface of the middle support block. In this way, the prefabricated road panel and the middle support block are connected together by the buckle block and the slot, the connection structure is stable, and the prefabricated road panel is not easy to warp or deviate after installation.

[0024] like Figure 1-Figure 6As shown, the assembled field road structure provided in this embodiment includes a compacted soil layer 1 and at least one row of prefabricated road panels 2 laid on the compacted soil layer 1, the middle part of the compacted soil layer 1 protrudes upward 36, and shoulder assembly positions are formed on both sides; the prefabricated road panels 2 are laid on the protrusions of the compacted soil layer 1, and the outer edges of the prefabricated road panels 2 near the left and right sides of the protrusions 36 extend out of the protrusions; prefabricated shoulders composed of a plurality of hard support components 3 connected to each other at the side ends and the inner sides of the upper ends connected to the outer edges of the road panels are laid on the two shoulder assembly positions; the hard support component 3 is composed of a first support block 31 and a second support block 32 connected to each other at the side ends, the first support block 31 is in an inverted T shape, and the two connected sides of its lower end extend outward to form a first connecting portion 33; the second support The block 32 is T-shaped, and the two adjacent sides of its upper end extend outward to form a second connection part 34 that cooperates with the first connection part 33; a road panel assembly groove 37 is provided on the inner side of the upper end of the first support block 31 and the second support block 32, and a plurality of drainage holes 39 are provided at intervals along the width direction of the first support block 31 and the second support block 32 at the lower end; the upper end surface of the hard support component 3 is higher than the upper end surface of the prefabricated road panel 2 or is flush with the upper end surface of the prefabricated road panel 2; a plurality of biological channels 38 are also provided along the width direction at the upper end of each first support block 31 and the second support block 32, and a plurality of biological passage through holes are provided on each prefabricated road panel 2, and the two ends of the biological passage through holes correspond to and are connected with the biological channels 38 of the corresponding side hard support component 3.

The specific steel bar configuration is set according to the required strength. Of course, the biological passage holes and biological channels 38 can be placed between the steel meshes or above the steel meshes.

[0026] If the first support block 31 and the second support block 32 are directly placed together without connecting the end faces, the strength of the shoulder formed will be weak and will not have good lateral pressure bearing performance. Therefore, in order to improve the lateral pressure resistance of the shoulder, a connection structure needs to be provided on the fitting surfaces of the first connecting portion 33 and the second connecting portion 34. Specifically, a vertical through hole can be provided and a cement column can be provided in the through hole to connect. The first support block 31 and the second support block 32 can also be connected by snap-fitting, and the specific structure of the snap-fitting is as follows: (1) An assembly groove 35 is provided at the upper end of the two first connecting portions 33 of each first support block 31 and along the width direction of the first support block 31; a protrusion 3636 matching the assembly groove 35 is provided at the lower end of the two second connecting portions 34 of each second support block 32.

[0030] Furthermore, the prefabricated road panels 2 are provided in two rows, and a plurality of middle support blocks whose upper ends are connected to the two prefabricated road panels 2 are embedded in the middle of the compacted soil layer 1 at the junction of the two rows of prefabricated road panels 2; and a lap step surface matching the road panel assembly groove 37 is provided on the left and right sides of each prefabricated road panel 2.
