Description

Technical Field

[0001] This utility model belongs to the field of roadbed technology, specifically relating to a geogrid composite hydraulic roadbed. Background Technology

[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetic materials, it has unique properties and functions. It is commonly used as reinforcement material in reinforced soil structures or composite materials. Geogrids are divided into four main categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids, and polyester warp-knitted geogrids. When laying water conservancy roadbeds, the use of geogrids can improve the strength of the roadbed, thereby increasing its service life.

[0003] When laying geogrids, adjacent geogrids need to be laid overlapping and connected with straps. However, the straps need to be tied one by one, and the bottom geogrid needs to be lifted to allow the straps to pass through it. This connection method increases the workload of geogrid laying and affects the laying efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a geogrid composite hydraulic roadbed, which facilitates the connection of two adjacent geogrid meshes and improves the connection efficiency, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a geogrid composite hydraulic roadbed, comprising a roadbed layer and a geogrid layer, wherein the roadbed layer contains several geogrid layers arranged sequentially from top to bottom, each geogrid layer includes several geogrid meshes arranged sequentially from left to right, one end of each geogrid mesh is provided with two connecting components, one of which is connected to an adjacent geogrid mesh via the two connecting components, and drainage channels are symmetrically provided at the top of the roadbed layer.

[0006] Furthermore, the connecting component includes equidistantly distributed connectors, and the connectors of two connecting components are staggered.

[0007] Furthermore, the connector includes an mounting plate, which is fixedly connected to the corresponding grid of the geogrid, and a connecting plate is fixedly connected to the top of the mounting plate.

[0008] Furthermore, a mating groove is provided on one side of the top of the connecting piece.

[0009] Furthermore, a slot is provided on one side of the bottom end of the connecting piece, and an inclined groove is provided at the bottom of one end of the connecting piece.

[0010] Furthermore, a limiting protrusion is fixedly connected to one side of the bottom end of the docking groove.

[0011] Furthermore, the grids of the adjacent geogrid layers are staggered.

[0012] Compared with the prior art, the beneficial effect of this utility model is that when laying the geogrid layer, after one geogrid is laid, the connection component of the other geogrid is engaged with the connection component of one end of the first geogrid, thereby completing the connection between the two adjacent geogrids and improving the connection efficiency.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 and 2As shown, a geogrid composite hydraulic roadbed includes a roadbed 1 and a geogrid layer 2. The roadbed 1 has a geogrid layer 2 inside, and the geogrid layer 2 has several layers, which are distributed from top to bottom. The geogrid layer 2 includes geogrid mesh 21, which has several geogrid meshes, which are arranged from left to right. One end of the geogrid mesh 21 is provided with two connecting components 22. One geogrid mesh 21 is connected to the adjacent geogrid mesh 21 through the two connecting components 22. Drainage channels 3 are symmetrically arranged at the top of the roadbed 1.

[0021] According to the above structure, when laying the roadbed, a road base layer 1 of a certain thickness is first laid, then compacted, and then a geogrid layer 2 is laid. Then, the road base layer 1 is laid on the geogrid layer 2 and compacted again. This process is repeated until the roadbed is completed. When laying the geogrid layer 2, after one geogrid mesh 21 is laid, one end of the other geogrid mesh 21 is connected to the connecting component 22 at one end of the first geogrid mesh 21 to complete the connection between the two adjacent geogrid meshes 21. When laying the geogrid mesh 21, U-shaped nails are used to fix the geogrid mesh 21 to the road base layer 1.

[0022] like Figure 3 and 4 As shown, the connecting component 22 includes equidistantly distributed connectors 23, and the connectors 23 of the two connecting components 22 are staggered. The connector 23 includes an mounting plate 231, which is fixedly connected to the corresponding grid of the geogrid 21. A connecting plate 232 is fixedly connected to the top of the mounting plate 231, and a mating groove 233 is provided on one side of the top of the connecting plate 232.

[0023] According to the above structure, when connecting two adjacent geogrids 21, one of the geogrids 21 is laid on the roadbed 1 using U-shaped nails, and then the connecting piece 232 is passed through the corresponding mesh at one end of the other geogrid 21, thereby completing the connection of the two geogrids 21.

[0024] like Figure 4 As shown, a slot 235 is provided on one side of the bottom end of the connecting piece 232, and a sloping groove 234 is provided at the bottom of one end of the connecting piece 232. A limiting protrusion 236 is fixedly connected to one side of the bottom end of the mating groove 233.

[0025] According to the above structure, after the top of the connecting piece 232 passes through the corresponding mesh, one side of the mesh is pressed down to one side of the inclined groove 234, and then the geogrid 21 is pulled back so that one edge of the mesh is inserted into the groove 235. Then the other side of the mesh is pressed down so that the other edge of the mesh is inserted into the bottom end of the limiting protrusion 236, thereby realizing that the mesh of one geogrid 21 is engaged with the connecting piece 23 of the adjacent geogrid 21, and thus realizing the connection of the two geogrids 21.

[0026] like Figure 1 and 2 As shown, in order to improve the overall strength of this roadbed, the grids of the adjacent geogrid layers 2 are staggered.

[0027] The working principle of this utility model is as follows: When laying the roadbed, a road base layer 1 of a certain thickness is first laid, then compacted. Next, a geogrid layer 2 is laid, followed by the road base layer 1 laid on top of the geogrid layer 2 and compacted again. This process is repeated until the roadbed is complete. When laying the geogrid layer 2, after one geogrid mesh 21 is laid, one end of the other geogrid mesh 21 is engaged with the connecting component 22 at one end of the first geogrid mesh 21, thus connecting the two adjacent geogrid meshes 21. U-shaped nails are used to fix the geogrid mesh 21 to the road base layer 1 during laying. When connecting the two geogrid meshes 21, [the following steps are taken]. One geogrid 21 is laid on the roadbed 1 using U-shaped nails. Then, the connecting piece 232 is passed through the corresponding mesh at one end of the other geogrid 21 to complete the connection of the two geogrids 21. After the top of the connecting piece 232 passes through the corresponding mesh, one side of the mesh is pressed down to one side of the inclined groove 234. Then, the geogrid 21 is pulled back so that one edge of the mesh is inserted into the groove 235. Then, the other side of the mesh is pressed down so that the other edge of the mesh is inserted into the bottom end of the limiting protrusion 236. Thus, the mesh of one geogrid 21 is engaged with the connecting piece 23 of the adjacent geogrid 21, thereby achieving the connection of the two geogrids 21.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
