Road Reinforcement Black High Strength HDPE Plastic Mesh

Earthwork Asphalt Pavement Road Reinforcement High Strength HDPE Uniaxial Plastic Geogrid

Uniaxial Plastic Geogrid Introduction

Plastic uniaxial geogrid is manufactured from plastic materials which may be high-density polypropylene or high-density polyethylene (HDPE) resins by the hot extruding process to make the resins into thin plates, the plates are punched into the regular holes for the formation of desired grids, and then the punching patterns are stretched longitudinally into the desired meshes to develop designed tensile strength.

Uniaxial Plastic Geogrid Specification

Compared with biaxial geogrid and uniaxial geogrid

Compared with biaxial geogrid production process, the uniaxial geogrid performs one-way stretching direction during production. In this process, the one-way stretched resins become directional linear state and forms an elliptical mesh integrity structure that is evenly distributed and has extraordinary tensile strength (＞150Mpa) and tensile modulus, it provides the soil with an ideal chain force system to bear and diffuse. Hengquan brand plastic uniaxial geogrid has the characteristics of high tensile strength, excellent bearing load capacity, high land optimization and soil erosion protection performance, easy construction, etc. The plastic uniaxial geogrid is the ideal geosynthetic product widely used for soil stabilization and reinforcement in road construction, retaining wall applications.

Uniaxial Plastic Geogrid Application

1. Uniaxial plastic geogrid for sale used to reinforce weak foundations.

2. Uniaxial plastic geogrid is used for reinforcing asphalt or cement pavement.

3. Uniaxial plastic geogrid is used to reinforce embankment slope and retaining wall.

4. Uniaxial plastic geogrid is used to reinforce river and sea embankments.

5. Uniaxial plastic geogrid for sale is used to treat landfills.

Key points of construction

Construction site: it is required to compact and level, and remove the sharp protuberances.

Grid laying: on the flat and compacted site, the main stress direction (longitudinal) of the grid installed and laid shall be vertical to the axis of the embankment, and the laying shall be flat without wrinkles, and shall be tensioned as far as possible. The main stress direction of the laid grid is the full length without joint. The connection between the width and width can be bound and overlapped manually, and the lap width is not less than 10 cm. If the grid is more than two layers, the joints between layers shall be staggered. After large area laying, the flatness shall be adjusted as a whole. After filling a layer of soil and before rolling, the grid should be tensioned again by manual or machine tools, and the force should be uniform to make the grid in the soil in a straight stress state.

Selection of filler: the filler shall be selected according to the design requirements. It has been proved by practice that except frozen soil, swamp soil, domestic garbage, chalk soil and diatomite, they can be used as fillers. However, gravel soil and sand soil have stable mechanical properties and little affected by water content, so they should be preferred. The particle size of filler shall not be greater than 15cm, and the grading of filler shall be controlled to ensure the compaction weight.

Paving and compaction of filling materials: when the grid is laid and positioned, it shall be filled and covered in time, and the exposed time shall not exceed 48 hours. The flow operation method of laying and backfilling can also be adopted. First pave the filler at both ends, fix the grid, and then push forward to the middle. The rolling sequence is from two sides to the middle. During rolling, the roller can not directly contact with the reinforcement material, and the vehicle is not allowed to drive on it for fear of dislocation of reinforcement material. The compaction degree of each layer is 20-30cm. The compactness must meet the design requirements, which is also the key to the success or failure of reinforced soil engineering.

Waterproof and drainage measures: in reinforced soil engineering, the drainage treatment inside and outside the wall must be done well; the foot protection should be done to prevent erosion; the filtration and drainage measures should be set in the soil, and if necessary, the geotextile and permeable pipe (or blind ditch) should be set. Drainage shall be conducted in the way of dredging, which shall not be blocked, otherwise hidden dangers will occur.
