After surface modification and coating treatment, the surface performance of the steel-plastic is changed, the composite performance with asphalt is improved, and the wear resistance and shear resistance of the substrate are greatly improved. When it is applied to asphalt overlay, it can play an important role in the following aspects. Slow down reflection cracks. The tensile force of the longitudinal geogrid at the center of the line is related to time. Compare the tensile value of the longitudinal geogrid at the center of the line and the shoulder. The final tensile values are all between /^-/, which are all smaller than the tensile force of the transverse geogrid, and No change. The two-way geogrid is used to increase the bearing capacity of the road (foundation) and prolong the service life of the road (foundation). The two-way geogrid is used to prevent the road (ground) from collapsing or cracking, and to keep the ground beautiful and tidy.

  When laying the geogrid overlap: the longitudinal distance is not less than the horizontal distance is not less than; the asphalt strips should be added on the previous geogrid, and then the second geogrid should be spread.

Compared with the previous plastic geogrid, it not only has strong bearing capacity, strong corrosion resistance and strong aging resistance, but also has a series of advantages such as high strength geomembrane, large friction coefficient, uniform perforation, convenient construction and long service life. It can effectively restrain the lateral displacement of the ground, greatly enhance the bearing capacity and occlusion of the foundation, effectively improve the interlocking of the reinforced bearing surface, and enhance the stability and firmness of the foundation. Effectively avoid damage caused by mechanical crushing and destruction during construction.

After special treatment, basalt fiber and polyester fiber were tested with high-density poly () unidirectional geogrid and polyester () bidirectional geogrid, and the weathered marl soil of the Xinxiang section of the central line project. With poly or polypropylene and other additives as raw materials, it is made into a composite type by extrusion. Under certain temperature conditions, the time of high polymer is a fixed value. However, the creep test of geogrid only considers the attenuation of the grid strength under long-term load, and the construction, filler, environment, etc. will also affect the strength of the grid during actual use. Therefore, the construction damage and soil The effects of pH, soil microorganisms, and geogrid connectors must also be considered. At the same time, the low elongation of the glass fiber geogrid reduces the deflection of the road surface and ensures that the road surface does not undergo transitional deformation. The above is about the relevant content of the polyester geogrid, I hope it will be helpful to everyone. 

Because some construction units used steel wire mesh in the past, the cost was very high and they were afraid of weather, sunlight, and rain. The use of the two-way geogrid greatly reduces costs and has a longer service life. Workers do not need regular maintenance, thereby reducing costs in all aspects. For the laying of reinforcing materials, the main strength direction of the reinforcing materials should be perpendicular to the wall and fixed with pins. The wall shall be filled with earth mechanically, and the distance between the wheel and the reinforcement shall be kept at least ㎝. After compaction, a layer of soil is about -㎝ thick.  

Due to the friction, bite force and interlocking force at the interface of the two materials, the lateral deformation of the soil is restricted, which is equivalent to applying a unilateral pressure increase to the soil, thereby improving the strength and bearing capacity of the soil.

The definition of geogrid: a two-dimensional grid-like or three-dimensional grid screen with a certain height that is made of polypropylene, polyvinyl chloride and other polymer polymers through thermoplastic or molding. When used as a civil engineering, It is called geogrid. , Geogrid Geogrid is a main geosynthetic material. Compared with other geosynthetic materials, it has unique properties.

Geogrid is a major geosynthetic material. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height, which is made of polypropylene and other high molecular polymers through thermoplastic or molding. When used as a civil engineering, it is called a geogrid.

Supplement: Geogrid is a two-dimensional grid-like or three-dimensional grid screen with a certain height that is made of polypropylene, polyvinyl chloride and other high molecular polymers through thermoplastic or molding. When used in civil engineering, It is called geogrid. The interlocking force of soil and rock materials in the grid increases, and the friction coefficient between them also increases significantly. , Anti-temperature performance: Due to the stretching effect, its high-temperature resistance performance is also improved.

In actual engineering, after the packing is compacted, it is not corroded by ultraviolet light and oxygen, so it can meet the requirements of permanent engineering construction. Engineering application fields: soft soil foundation reinforcement of highways, railways, bridge abutments, approach roads, wharfs, dams, slag yards, etc., retaining walls and pavement crack resistance projects.

When the slope surface is uneven, the laying of geocells is prone to stress concentration, which will crack the solder joints of the cell and form a cell straddle. Therefore, it is necessary to level the slope to the planning requirements, and choose manual slope repair to remove pumice and dangerous rocks on the slope.

The structure of the eruption trough of the embankment slope, which can flow into the drainage, should be provided with a flat trickle channel, and the edge of the road and the opening should enter the transition part. Part of the road edge being washed away, drainage ditch, or interception is provided with water sticking to the opening of the trough water jet directed away from the movement of the embankment and the embankment high eruption trough should be connected with speaker openings. , The slope surface is flattened to remove some debris that is not conducive to cell paving, so that the slope surface is flat and strong. You can also sprinkle a layer of high-quality soil first to facilitate plant growth. , Cells should be laid from top to bottom in the main force direction, so that the cell sheet weight is perpendicular to the roadbed. It must not be laid horizontally. The side slope of the pavement cell should be set up with a main drainage ditch system, and the interval between two adjacent ditches should be maintained. The drainage ditch is connected with the side ditch of the road, so that the road area flows along the side ditch into the drainage channel and enters the side of the road. The road surface is watery to avoid scouring the cell slope protection.

The two-way tensile geogrid is mainly used for the reinforcement of soft soil projects such as highways and railways, as well as slope protection and large-scale garbage projects. It can greatly enhance the bearing capacity of the soft soil foundation, avoid cracks and collapses on the surface, facilitate construction, and reduce Repair fees.

Meanwhile, the geogrid s a kind of geotechnical composition material that is used more on highways nowadays. It is a plate with a square grid formed by stretching a polymer polymer.
