High-tech construction Shaoyang 15005383108 Pu waterproof blanket of claim 1, should be checked before GCL construction grass, grass-roots level should be compacted, potholes no water, no stones roots and other sharp objects. 2, waterproof blanket in handling and construction process to try to avoid vibration and shock, avoid blanket body have a greater degree of curvature, the best time to place. 3, in the GCL installation, inspection after backfilling to work as soon as possible, if the process is in line with the work of HDPE geomembrane geomembrane pavement should be welded to prevent the rain or torn. Waterproof blanket product protection 1, after the waterproof blanket laying should be promptly laid geomembrane to avoid withstand wind and rain erosion; 2, if not promptly after the laying of geomembrane waterproof blanket laying is completed, you should use the color of the cloth or mulch to avoid withstand wind and rain erosion; 3, waterproof blanket laying is completed to avoid damage to the vehicle rolling and other foreign matter; 4, after the completion of construction of the bentonite mat may not have mud, dirt, and other debris can damage the impermeable layer The foreign matter. Storage, transportation, a, GCL (GCL) volumes before installing Expand to avoid damage. GCL (GCL) volumes should not water stacked in place by smooth, high stack height does not exceed four volumes, and can see the identification plate volume. 5, from improper storage and handling caused by GCL (GCL) of damage, are not allowed on this project. 6, in the transport process (including on-site storage location from the material to the work of transport), GCL (GCL) volumes should be avoided damage. 7, physical damage of waterproof blanket (GCL) volumes must be repaired, damaged seriously GCL (GCL) can not be used, we moved from the field and replace. 8, any exposure to chemical solvents leak bentonite (GCL) materials, according to the judgment of the Engineer, are not allowed on this project. 9, if the bentonite blanket during installation in damage (tearing, puncture, etc.), can be cut from a roll of new carpet bentonite "patch" to cover the damaged areas repaired. Where the length of the four sides from the damaged patch can not be less than 300mm, laying "patch" before should sprinkle some granular bentonite or bentonite slurry around the damage. If necessary, use some adhesive to prevent "patch" the shift, or in damaged areas underneath a small piece of bentonite blanket. Sodium bentonite waterproof blanket Scope This standard specifies the sodium bentonite waterproof blanket product classification, specification and code, technical requirements and test methods, inspection rules, marking, packaging, storage and transportation. This standard applies to the field of subways, tunnels, artificial lakes, landfills, airports, water conservancy, road and bridge, construction of water, seepage to sodium bentonite used as the main raw material, the use of acupuncture, acupuncture film law or glued production of sodium bentonite waterproof blanket (the GCL).
