Detailed construction guidelines for Hubei steel-plastic geogrids
Release date:
2020-12-27
Hubei Xiangyang Steel-Plastic Geogrid It is made by combining steel-plastic strips through an innovative process. Thanks to the product's surface, which is rolled into a regular, coarse pattern, it can effectively withstand tremendous tensile stress when laid within the compacted soil layer—and also provides significant friction against the surrounding fill material.
Hubei Xiangyang Steel-Plastic Geogrid The main steps for laying it are as follows:
1. Laying fiberglass Hubei Xiangyang Steel-Plastic Geogrid At that time, ensure smooth and even placement, keeping the material taut. The recommended transverse overlap length is 50–100 mm, while the longitudinal overlap should be 150–200 mm. Additionally, depending on the direction of paving, press the trailing end under the preceding one.
2. Roll using a pneumatic tire roller.
3. Requirements include being flat with no warping at the corners; edges should ideally be chamfered, using 2-inch steel nails (high-quality cement nails).
4. When installing the fiberglass Xiangyang, Hubei steel-plastic geogrid using the nail-fixing method, first secure one end to the lower layer structure that has already been sprayed with a tack coat of asphalt, using fixing metal plates and nails. The nails can be driven in by hammering or shot using a specialized gun. Then, as the grid is pulled tightly along its length, the fiberglass strands remain straight and fully tensioned across the width.
5. When fixing with nails, the overlap distances for the grating are as follows: the longitudinal joint overlap must be at least 15 cm, and the transverse overlap should be no less than 5 cm. Longitudinal overlaps should place the previous sheet over the subsequent one, following the direction of asphalt paving.
6. When securing, do not nail into the fiberglass, nor strike the fiberglass directly with a hammer. If, after installation, you notice any broken nails or loose metal sheets, re-secure them immediately.
7. To prevent construction vehicles' tires from sticking the fiberglass grid and tack coat together, as well as to avoid slippage of asphalt concrete paver wheels, stone chippings should be spread evenly on the surface of the tack coat. The recommended amount of stone chippings is 3–5 m³ per 1,000 m². i. Construction must not be carried out when the ambient temperature is below 10°C or when the road surface is wet.
8. The construction method for the asphalt surface layer is consistent with that of a standard asphalt pavement, but care must be taken to ensure that construction vehicles do not make sharp turns or sudden brakes on the surface of the fiberglass grid.
Hubei Xiangyang Steel-Plastic Geogrid The key construction points can be divided into five aspects:
1. The fill material should be selected according to the project specifications. Practice has shown that materials such as frost-susceptible soil, swamp soil, domestic waste, chalk, and diatomaceous earth can all be used as fillers—though gravelly and sandy soils exhibit more stable mechanical properties and are less affected by moisture content, making them preferable choices. The particle size of the fill material must not exceed 15 cm, and care should be taken to control the gradation of the filler to ensure optimal compaction density.
2. In geotechnical engineering, it is essential to properly manage drainage both on the surface and within the walls; ensure adequate toe protection to prevent erosion, and incorporate filtration and drainage systems inside the soil mass. When necessary, install geotextiles or permeable pipes (or drainage trenches). Adopt a guided drainage approach—never allow blockages, as this could lead to hazardous situations.
3. Request that the construction site and work area be compacted and leveled, ensuring a perfectly horizontal surface and removing any sharp protrusions or obstacles.
4. When Hubei Xiangyang Steel-Plastic Geogrid After positioning the geogrids, backfilling should be carried out promptly to cover them—exposure should not exceed 48 hours. Alternatively, a continuous workflow method can be adopted, where backfilling is done simultaneously as the geogrids are laid. Begin by spreading and placing fill material at both ends, securing the geogrids in place, then gradually advance toward the center. When compacting, follow the sequence of first compacting the sides before moving to the center. Importantly, during compaction, the roller must never come into direct contact with the geogrid material. Additionally, vehicles should generally be prohibited from driving over areas that haven’t yet been fully compacted, to prevent displacement of the geogrids. Each layer should be compacted to a thickness of 20–30 cm. Crucially, the degree of compaction must meet the design specifications—this is often the key determinant of success or failure in geotechnical projects.
5. Installation and laying of the barrier on a flat, compacted surface Hubei Xiangyang Steel-Plastic Geogrid Its primary load direction (longitudinal) should be perpendicular to the embankment axis, with a smooth, wrinkle-free installation achieved by stretching it taut as much as possible. Secure the material using stakes and backfilling with soil and rock, ensuring the laid material is firmly anchored in place. Hubei Xiangyang Steel-Plastic Geogrid The primary load direction runs continuously without splices, while connections between individual sections can be manually tied and lapped, with a lap length of at least 10 cm. If installed, Hubei Xiangyang Steel-Plastic Geogrid On levels above the second floor, the layers should be staggered. After laying out large areas, the overall flatness must be adjusted. Once a layer of soil has been filled and spread but before compaction, the geogrid should be re-tensioned—either manually or with machinery—ensuring even pressure across the surface to achieve optimal alignment. Hubei Xiangyang Steel-Plastic Geogrid In the soil, it is in a straightened, stress-bearing state.
