Description

Technical Field

[0001] The utility model relates to the technical field of assembled roads, in particular to an assembled composite water-permeable pavement structure. Background Art

[0002] It is well known that prefabricated road structures have fast construction speed, good quality and low environmental impact. They are suitable for rapid maintenance of heavy-load passages with heavy traffic, rapid repair of collapsed roads, and new or rebuilt roads that need to be completed and opened to traffic quickly.

[0003] The specific construction steps of the prefabricated road structure are to arrange the combined rigid prefabricated blocks in a honeycomb shape to form the appearance characteristics of the prefabricated structure and lay them on the road surface, and then use a flexible asphalt structure layer to fill the unreserved inclined gaps on the rigid prefabricated blocks to form a rigid-flexible composite force-bearing structure to complete the paving of the prefabricated road.

[0004] During the process of paving the prefabricated road, positioning steel plates are used to clamp the two sides of the prefabricated blocks arranged in a honeycomb shape, and then steel bars are passed through the prefabricated blocks located in the same horizontal direction and then fixed with threaded fasteners. This fixing method requires that multiple threaded fasteners be threadedly connected to the passed steel bars in turn, which is inconvenient to operate and reduces the efficiency of transportation and paving of the prefabricated road structure. Utility Model Content

[0007] Preferably, each of the positioning steel plates is a rectangular structure, which fits with the prefabricated blocks on both sides of the prefabricated block group.

[0008] Preferably, the locking plate is a rectangular structure, and when each of the retaining rings is engaged with each of the locking grooves, the locking plate is located within the limiting portion.

[0009] Preferably, each of the snap rings is of a rectangular structure as a whole, and when the locking plate is pressed down, each of the snap rings slides and snaps into each of the locking grooves.

[0010] Preferably, the prefabricated block group is composed of a plurality of prefabricated blocks arranged in an array.

[0011] Preferably, each of the prefabricated blocks consists of a prismatic portion and a honeycomb portion connected to the prismatic portion.

[0012] Preferably, each of the honeycomb parts is provided with a through hole which is matched with the positioning rod.

[0013] In the above technical scheme, the assembled composite permeable pavement structure provided by the utility model has the following beneficial effects: when laying the prefabricated block group, the two positioning steel plates are attached to the prefabricated blocks on both sides of the prefabricated block group and connected by the positioning rods. Figure 1 As shown in the state, the snap ring on the locking plate is then aligned with the locking groove on the positioning steel plate and pressed down, so that the snap ring is engaged with the locking groove, and at the same time, the locking plate is engaged with the limiting portion on the positioning rod, as shown in FIG. Figure 2 to Figure 1 As shown in the state, the paving of the assembled composite pavement is completed. The device fixes the prefabricated block group by clamping, which is easy to operate and improves work efficiency.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] See also Figure 1-3 The assembled composite permeable pavement structure is used to solve the problem that in the process of paving the assembled road, the two sides of the prefabricated blocks arranged in a honeycomb shape are clamped by positioning steel plates, and then the steel bars are passed through the prefabricated blocks located in the same horizontal direction and then fixed with threaded fasteners. This fixing method requires multiple threaded fasteners to be threadedly connected with the penetrating steel bars in turn, which is inconvenient to operate and reduces the transportation and paving efficiency of the assembled road structure.

[0022] As a further technical solution proposed by the present invention, the prefabricated block group 1 also includes: a positioning steel plate 2, which is relatively arranged on the prefabricated block group 1, and at least two locking grooves 2.1 are provided on the positioning steel plate 2; a positioning rod 3, which passes through the positioning steel plate 2 and the prefabricated block group 1, and a limited portion 3.1 is provided on the positioning rod 3; a locking plate 4, which is adapted to the limited portion 3.1, and a clamping ring 4.1 matching each locking groove 2.1 is provided on the locking plate 4. Specifically, when laying the prefabricated block group 1, the two positioning steel plates 2 are attached to the prefabricated blocks on both sides of the prefabricated block group 1 and connected by passing through the positioning rod 3, such as Figure 1 As shown in the state, the snap ring 4.1 on the locking plate 4 is then aligned with the locking groove 2.1 on the positioning steel plate 2 and pressed down, so that the snap ring 4.1 is engaged with the locking groove 2.1, and the locking plate 4 is engaged with the limiting portion 3.1 on the positioning rod 3, as shown in the state. Figure 2 to Figure 1 As shown in the state, the paving of the assembled composite pavement is completed. The device fixes the prefabricated block group 1 by means of a clamping method, which is easy to operate and improves work efficiency. It weakens or even avoids the threaded connection of multiple threaded fasteners with the penetrating steel bars in sequence, which is inconvenient to operate and reduces the transportation and paving efficiency of the assembled road structure.

[0023] The specific numbers of the snap rings 4.1 and the locking grooves 2.1 in this embodiment are set according to the requirements of those skilled in the art.

[0024] In another embodiment of the present invention, preferably, each positioning steel plate 2 is specifically a rectangular structure, which fits with the prefabricated blocks on both sides of the prefabricated block group 1, such as Figure 1 As shown in the state, during the transportation or laying process, the positioning steel plate 2 is used to fit with the two sides of the prefabricated block group 1 to limit and fix it.

[0025] In another embodiment of the present invention, preferably, the locking plate 4 is specifically a rectangular structure. When each clamp ring 4.1 is engaged with each locking groove 2.1, the locking plate 4 is located in the limiting portion 3.1. Further, when the locking plate 4 is engaged with the locking groove 2.1, each positioning rod 3 is limited and fixed. Figure 1As shown in the status, after installation, the three cooperate with each other to complete the paving of the assembled pavement structure. In the subsequent operation, the flexible asphalt structure layer will fill the inclined gap reserved on the upper part of the rigid prefabricated block group to form a rigid-flexible composite force-bearing structure. The high-strength honeycomb assembled blocks and the excellent anti-destruction property of the rigid-flexible composite increase the life of the road. When it rains, the seepage water is discharged through the grooves under the honeycomb blocks to avoid water stagnation in the road structure layer and water damage to the structure layer.

[0026] In another embodiment of the present invention, preferably, each snap ring 4.1 is in a rectangular structure as a whole. When the locking plate 4 is pressed down, each snap ring 4.1 slides into each locking groove 2.1. Figure 2 As shown in the state, when the clamping ring 4.1 corresponds to the locking groove 2.1, it is pressed down and clamped therein, so that the locking plate 4 cooperates with the positioning steel plate 2 and the positioning rod 3 to complete the installation.

[0027] In another embodiment of the utility model, Figure 1 As shown in the state, the prefabricated block group 1 is composed of a plurality of prefabricated blocks arranged in an arrangement, each prefabricated block specifically consists of a prism-shaped portion 1.3 and a honeycomb portion 1.2 connected to the prism-shaped portion 1.3. Furthermore, the prefabricated block is a building block with a honeycomb shape at the bottom and a hexagonal shape at the top. The overall structure of the plurality of building blocks is combined in a honeycomb shape and arranged, forming the appearance characteristics of the assembled structure.

[0028] In another embodiment of the utility model, each honeycomb portion is provided with a through hole 1.1, which is adapted to the positioning rod 3. This is the prior art. The through hole 1.1 on the honeycomb portion of each prefabricated block is used to connect with the positioning rod 3. Figure 1 As shown in the state, the positioning rod 3 passes through the positioning steel plate 2 and the prefabricated block to connect the two.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
