Description
Technical Field
The utility model relates to a road equipment field, particularly, the utility model relates to a compound geotechnological cloth of grid for road.
Background
The road needs to be constructed under various geological conditions due to the large span. In addition to tunnels in mountainous areas, it is also necessary to treat soft foundations. The adoption of the geogrid has obvious advantages compared with the traditional digging and filling mode. The geogrid matched gravel cushion layer is not limited by time, geographical position, geographical condition and land type, the defects and limitations of the conventional method are overcome, and the geogrid matched gravel cushion layer has the advantages of reinforcement, isolation, reinforcement and reinforcement. In addition, in all engineering fields of soft foundation treatment, reinforcement and the like, geogrids can be used for reinforcement treatment to enhance the overall acceptance characteristics of the foundation and prevent local settlement. The existing grid composite geotextile is designed more traditionally, only a grid-shaped grid is fixed on the geotextile, and the grid composite geotextile with the structure is usually of a single-layer structure, cannot lay a multi-layer structure in soil at the bottom of a road, and cannot three-dimensionally enhance the combination stability of a road foundation.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a compound geotechnological cloth of grid for road can lay multi-level structure in road bottom soil, can strengthen the combination steadiness of road bed three-dimensionally.
In order to achieve the above object, the present invention provides the following technical solutions:
this a compound geotechnological cloth of grid for road includes a plurality of non-woven geotechnological cloths, and the top surface and the bottom surface of non-woven geotechnological cloth correspond the position and all are equipped with the frame of rectangle frame form, and the inside of frame all is equipped with netted grid, and the netted intersection point of grid all is equipped with flat node piece, and node piece all is connected with non-woven geotechnological cloth stitching through the nylon wire, all is connected with even rope on a plurality of node pieces, is equipped with mutual screw-thread fit's screwed pipe and threaded rod on the even rope respectively.
As a further optimization of the technical scheme, the frame, the grating and the node pieces are all made of polypropylene plastics and are all of an integral structure.
As a further optimization of the technical scheme, the non-woven geotextile is a polyester non-woven geotextile with filament needling.
As a further optimization of the technical scheme, the connecting ropes are made of nylon materials and are connected with the node pieces, the threaded pipes and the threaded rods through the bonding agents.
As a further optimization of the technical scheme, the threaded pipe and the threaded rod are both made of hard PVC plastics.
The beneficial effect of adopting above technical scheme is: when the grid composite geotextile for the road is used, the non-woven geotextile can be laid on each soil layer of soil at the bottom of a road bed, the soil is filled after a layer of non-woven geotextile is laid, and then a layer of non-woven geotextile is laid. The screwed pipe and the threaded rod of the upper and lower layers of non-woven geotextile are screwed and connected, and the reinforcing effect of the frame and the grid is integrated, so that the combination stability of the road subgrade can be enhanced three-dimensionally. The grid composite geotextile for the road can lay a multi-layer structure in soil at the bottom of the road, and can be used for enhancing the combination stability of a road subgrade in a three-dimensional manner.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a front view of the grid composite geotextile for a road;
fig. 2 is a plan view of the grid composite geotextile for road.
The high-strength concrete comprises 1-non-woven geotextile, 2-frames, 3-grids, 4-node sheets, 5-connecting ropes, 6-threaded pipes and 7-threaded rods.
Detailed Description
Preferred embodiments of the grid composite geotextile for roads will be described below with reference to the accompanying drawings.
Fig. 1 and 2 show a specific embodiment of the grid composite geotextile for a road:
combine fig. 1 and fig. 2, this a compound geotechnological cloth of grid for road includes a plurality of non-woven geotechnological cloth 1, non-woven geotechnological cloth 1's top surface and bottom surface correspond the position and all are equipped with frame 2 of rectangle frame form, the inside of frame 2 all is equipped with netted grid 3, the netted intersection point of grid 3 all is equipped with flat node piece 4, node piece 4 all sews up with non-woven geotechnological cloth 1 through the nylon wire and is connected, all be connected with even rope 5 on a plurality of node pieces 4, be equipped with mutual screw-thread fit's screwed pipe 6 and threaded rod 7 on the even rope 5 respectively. The threaded tube 6 and the threaded rod 7 can be screwed together.
The frame 2, the grating 3 and the node pieces 4 are all made of polypropylene plastics, and are firm and durable, the manufacturing cost is relatively low, and the frame 2, the grating 3 and the node pieces 4 are all of an integral structure. The non-woven geotextile 1 is a polyester non-woven geotextile with a long yarn needle. The connecting rope 5 is made of nylon materials, is firm and durable, and is connected with the node pieces 4, the threaded pipes 6 and the threaded rods 7 through adhesives or the connecting rope 5 penetrates through yielding holes of the threaded pipes 6 and the threaded rods 7 to be connected tightly.
