Construction process of composite geomembrane

Before the laying of the composite film, the earthwork of the channel is filled and the slope surface is finished. The flatness and compaction of the slope surface meet the design requirements and the laying of the composite film can only be carried out after the acceptance of the supervision engineer. 1. Construction preparation 1) Quality inspection of composite membrane materials. The composite high quality fiberglass geogrid used in the project is a two-cloth one-membrane composite geomembrane. Before use, the quality inspection center station is entrusted to inspect various technical indicators of the product. All indicators meet the standards and design requirements. 2) Clearing and leveling the dike slope, removing all sharp-angled debris, backfilling the rammed under-slope, sloping the rich slope and passing the supervision and acceptance, and providing a working surface for the laying of composite geomembrane 3) Splicing in the geomembrane field In order to facilitate the construction and ensure the splicing quality, the composite wholesale fiberglass geogrid should be as wide as possible to reduce the amount of on-site splicing. Before construction, the composite geomembrane width and site length needs to be cut in the unit and spliced. To meet the required size of the block, roll it on the steel pipe, and manually transport it to the working surface to lay it, and it is necessary to avoid damage to the material.
