The first industry-standard waterproof blanket waterproof blanket Jiantong 13,639,450,809 brand bentonite waterproof blanket construction method: 1, waterproof blanket material larger self, should adopt the shovel transport aircraft handling, laying. 2. Connect waterproof blanket material using an overlapping manner. 3, should be waterproof blanket on slopes greater than 10% of the number of laying minimize overlap along the longitudinal direction of the slope, the slope of the GCL must toe the line more than 1500mm above. D, we will be in strict accordance with the submitted to the Engineer's waterproof blanket to lay laying design, except with the owner or supervision requirements. 4, any equipment used for laying waterproof blanket has been laid not traveling well above geosynthetics. When installing waterproof blanket, outdoor air temperature not lower than 0 ℃ or above 40 ℃. 5, all waterproof blanket exposed edges must be immediately pressed with sandbags or other heavy objects, in order to prevent the wind or waterproof blanket pulled around the anchoring groove. GCL can not commence under windy conditions to prevent windblown. 6, paving the way waterproof blanket waterproof blanket must ensure that the following direct contact with the ground, remove wrinkles. Any wrinkled, folded, or are likely to cause soil arching other geotextile material occurs the same situation, in order to avoid wrinkles, folds and arched, we will pass on the GCL re-laying or cut according to the requirements of technical notes and repair to eliminate these problems. 7, waterproof blanket of equipment must be approved by the supervising engineer to use, does not allow the use of unprotected razor or "quick knife." I, possible damage to the bentonite blanket construction equipment can not be directly applied to the bentonite blanket. Laying method is feasible bulldozing running back, the hanging front of the bentonite before bulldozers rolled blanket. If the soil machines on Indian soil leaving the car, laying work should continue before restitution. 8, to minimize drag on the ground bentonite blanket of bentonite carpet laying, in order to avoid damage to the bentonite blanket contact with the ground surface. If necessary, you can add a layer of temporary geotextile put on the ground, in order to reduce damage to the bentonite blanket laying process due to friction caused. 9, bentonite blanket laying and bonding should be inclined in a direction parallel with the slope, if the slope is greater than 4: 1, from the top of the hill or incline within 1m, bentonite blanket can not have a lateral overlap. 5, overlapping a, bentonite blanket is an overlap of two ends of bentonite blanket overlapping lap. To prevent loose soil or gravel into the lap area. Waterproof blanket construction requirements: 1, waterproof blanket should be checked before construction grassroots, grassroots should be smooth, no potholes water, no stones roots and other sharp objects. 2, waterproof blanket in handling and construction process to minimize vibration and shock, the best time to put in place. 3, in the GCL installation, inspection after the installation of HDPE geomembrane to be as soon as possible to prevent the rain or torn, dirty. Finished waterproof blanket of protection: 1, waterproof blanket laying should be promptly laid geomembrane to avoid withstand wind and rain erosion; 2, if not timely laying geomembrane should be used after the color of the cloth or film waterproof blanket laying is completed cover to avoid withstand wind and rain erosion; after c, waterproof blanket laying is completed to avoid damage to the vehicle rolling and other foreign matter; 3, bentonite mat after completion of construction shall have mud, dirt, and other debris can damage the seepage foreign matter layer is present. Storage, transportation, a, GCL (GCL) before installing the expanded volume to avoid damage. GCL (GCL) volume should not water stacked in place by the formation of high stack height does not exceed four volumes, and can see the identification plate volume. b, by improper storage and handling caused by GCL (GCL) of damage, are not allowed on this project. c, in the transport process (including on-site storage place to work from the material transport), GCL (GCL) volumes should be avoided damage. d, physical damage of GCL (GCL) volume must be repaired, damaged seriously GCL (GCL) can not be used, we move away from the site and replaced. e, any exposure to chemical solvents leak bentonite (GCL) materials, according to the judgment of the Engineer, are not allowed on this project 13,639,450,809
