    Standard Practice for Construction of Geogrid for Subgrade Engineering

    Construction process: Construction preparation (material transportation, setting out) → substrate treatment (cleaning) → geogrid laying (laying method, overlap width) → filler (method, particle size) → rolling geogrid → lower geogrid paving.

    Talking about the construction technology of geogrid on asphalt concrete pavement

    Asphalt pavement is a general term for pavements that use asphalt as a binder to supplement the surface layer. It is suitable for roads with various traffic volumes. Because the road surface built with asphalt is black, it is also called black pavement. As the asphalt pavement uses a strong asphalt material, the bonding force between the mineral materials is greatly strengthened, thereby improving the strength and stability of the mixture, and improving the quality and durability of the pavement. In the process of asphalt pavement construction, quality control and inspection of geogrids are the most important part of ensuring quality. It has a great impact on the construction quality. The specific requirements for quality control during the construction process should be implemented in accordance with the relevant construction technical specifications. This is very important to ensure the construction quality of the geogrid on the asphalt pavement. , Geogrid is used for joint treatment of asphalt pavement, please look down.

    Geotextile laying process instruction manual (the most comprehensive and strictest)

    1. Storage, transportation and handling of geotextile Geotextile rolls should be protected from damage before installation and deployment. Geotextile rolls should be stacked in a place where there is no water accumulation, the height of the pile should not exceed four rolls, and the identification sheet of the roll can be seen. Geotextile rolls must be covered with opaque materials to prevent UV aging. During the storage process, the integrity of the label and the data must be maintained. During the transportation process (including the transportation from the material storage site to the work site), the geotextile roll must be protected from damage. Geotextile rolls that have been physically damaged must be repaired. Geotextiles that are severely worn cannot be used. Any geotextile exposed to leaking chemical reagents is not allowed to be used in this project.

    HDPE smooth geomembrane construction scheme process detailed explanation

    HDPE geomembrane is a kind of waterproof barrier material produced with high-density polyethylene resin as raw material. This kind of material has a high degree of resistance to high temperature, aging, and adaptability to the environment. General tests show that the service life of hdpe geomembrane can be long. It has been widely used in the fields of environmental protection and aquaculture for more than 50 years. Here is how to construct it:

    Construction scheme and coordination measures of HDPE Geomembrane laying in slag yard(2)

    6, Geomembrane anchoring requirements ① The anchorage shall not disturb the soil at the bottom of the ditch during the excavation process. The bottom of the ditch is flat and free of loose soil. The depth and slope of the ditch wall meet the design requirements; ②Before backfilling the anchored trench, the bottom of the trench should not be soaked with water, and the accumulated water should be discharged in time; ③ The backfilling of the anchoring trench should be timely, and the soil quality of the backfilling soil should meet the design requirements. The backfilling soil should be layered and compacted by a small compaction machine with a compaction degree of not less than 93%; ④During the laying process, prevent any damage to geosynthetics materials due to loading and unloading activities, high temperature, chemical substance leakage or other factors; ⑤ The laying tools shall not damage the normal use function of the geosynthetics materials, and the mechanical equipment used for construction shall not cause obvious scratches on the geosynthetics materials and damage to the surface of the laying substrate; ⑥ When adjusting the overlap width of the material during laying, the connected parts must not be damaged, and the installed geomembrane must not damage the installed geomembrane when adjusting the position; ⑦If construction is carried out on rainy days, construction must be carried out after feasible measures have been obtained and confirmed by the supervisor and the owner’s representative; ⑧ There must be enough temporary ballast (sand bags) during construction to prevent the laid geomembrane from being blown up by strong wind. In the case of strong wind, the geomembrane must be temporarily anchored and installation work suspended.
