The water seepage can be caused after the pavement is cracked, the pavement water damage can be caused, the service life of the road is influenced, the driving safety is influenced, the maintenance workload and the maintenance cost are increased, and the normal passing, the attractiveness and the driving comfort are influenced. Therefore, it is necessary to develop a composite grid geotextile with high tensile strength and good anti-seepage effect.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a grid geotextile, which has high tensile strength, can form a reinforced impervious layer after being bonded by asphalt, has good frost resistance, long service life, convenient and quick construction, simple process and no need of independent fixation.
The technical scheme provided by the utility model for solving the technical problem is as follows:
the geogrid geotextile consists of a grid and geotextile, wherein the grid consists of transverse grid bars and longitudinal grid bars, the transverse grid bars are arranged on the longitudinal grid bars, the geotextile is fixed below the longitudinal grid bars, the grid is in a two-dimensional grid shape formed by thermoplastic molding or die pressing or in a three-dimensional grid shape with a given height, the cross section of each grid bar is rectangular or square, the geogrid geotextile is laid on the top surface of a base layer, and the geotextile surface is bonded with the top surface of the base layer.
The geotextile and the grid are bonded by bonding materials or sewn together by a sewing process.
The grating is a two-dimensional grid or a three-dimensional grid with a given height, which is formed by thermoplastic or die pressing of high polymer polymers such as polypropylene, polyvinyl chloride and the like.
The grid is a rectangular grid, and the size of the grid can be 15cm in the transverse direction by 30cm in the longitudinal direction or 10cm in the transverse direction by 20cm in the longitudinal direction.
The geotextile is a filament non-woven geotextile which is made of polypropylene serving as a main material by adopting a needling process through spinning, drafting and lapping.
The width of the grid geotextile is 3-6.5 meters, and the length is about 150-200 meters.
The grid geotextile is transversely and longitudinally widened and lengthened in a splicing mode, the longitudinal direction is in butt joint with staggered joints, and the length of the staggered joints is 3-5 m.
The utility model has the advantages that: 1. the tensile strength is high, the grating and the geotextile are jointly stressed in a composite mode, and the longitudinal grating of the grating is dense, so that the longitudinal tensile strength can be improved, and the occurrence of transverse cracks of the pavement is reduced; 2. the grid geotextile can form a reinforced impervious layer after being bonded by asphalt, so that the damage to the pavement caused by water infiltration can be reduced; 3. the grating is well combined with the asphalt pavement surface layer, and the grating can play a role in reinforcing the pavement; 4. the antifreezing property is good, the acid and alkali resistance is good, and the service life is long; 5. the construction is convenient and fast, the process is simple, and independent fixation is not needed.

Detailed Description
The geogrid geotextile consists of a grid and geotextile, wherein the grid consists of transverse grid bars and longitudinal grid bars, the transverse grid bars are arranged on the longitudinal grid bars, the geotextile is fixed below the longitudinal grid bars, the grid is in a two-dimensional grid shape formed by thermoplastic molding or die pressing or in a three-dimensional grid shape with a given height, the cross section of each grid bar is rectangular or square, the geogrid geotextile is laid on the top surface of a base layer, and the geotextile surface is bonded with the top surface of the base layer.
The grid is a rectangular grid, and the size of the grid can be 15cm in the transverse direction by 30cm in the longitudinal direction or 10cm in the transverse direction by 20cm in the longitudinal direction.
The geotextile is a filament non-woven geotextile which is made of polypropylene serving as a main material by adopting a needling process through spinning, drafting and lapping.
The width of the grid geotextile is 3-6.5 meters, and the length is about 150-200 meters.
The grid geotextile is transversely and longitudinally widened and lengthened in a splicing mode, the longitudinal direction is in butt joint with staggered joints, and the length of the staggered joints is 3-5 m.
Installation location and procedure: the grid geotextile is mainly laid on the top surface of the base layer of the pavement. And removing the floating soil and sundries on the top surface of the base layer. Firstly, after the asphalt or emulsified asphalt is uniformly sprayed, the spraying amount of the asphalt is controlled to be 1.1kg/m2The spreading amount, the spreading uniformity and the asphalt quality are strictly controlled; and then, mechanically paving the grid geotextile on the top surface of the base layer to bond the geotextile surface and the top surface of the base layer, and longitudinally butting, tensioning and paving the geotextile surface and the top surface of the base layer.
