The national standard impermeable membrane GH2 protects the impermeable membrane GH2 during the construction of the leachate gravel guide layer. The leachate guide layer generally uses pebble or gravel materials, and the thickness should not be less than 30cm. Due to the large landfill area and the amount of gravel paving work is very large, how to solve the problem of preventing damage to the impermeable membrane GH2 during gravel transportation and paving on the impermeable membrane GH2 is very critical. Using the operation method of zoning construction, each laying of 4 films is used as an operation unit, a 5mm thick steel plate is laid on the impermeable membrane GH2 as a material transportation channel, gravel walkways with a thickness of 1.5 meters or more are laid at a certain distance, and then the gravel is paved from the inside to the outside using an excavator on the walkway. Through the anti-leakage test, this construction measure has a good protective effect on the HD impermeable membrane GH2, and very little damage to the impermeable membrane GH2. Instructions for the use of composite geomembrane: First, plan according to the actual terrain size → cut the film according to the actual planned size and transport it to the corresponding position on the construction site → lay and weld according to the construction operation procedure → apply for acceptance after self-inspection is qualified, and prepare for the next process. Special part laying: When laying the film at the foot of the slope of the slope and the intersection of the slope, the soil foundation is required to be smooth and smooth when turning, and no negative slope can occur. Relax as much as possible when applying the film, and do not let the film hang. Film laying procedure: The laying team first checks whether the number of each film in the laying area is consistent with the number of the floor plan. After confirming that it is correct, the position of the film is fixed according to the regulations, immediately use a sandbag for temporary anchoring, and then check whether the lap width of the diaphragm meets the requirements of about 100mm, and adjust it in time when it needs to be adjusted, and fully prepare for the road process. Composite geomembrane welding procedure: Before welding geomembrane construction, sample welding must be done first, and formal welding can only be started after the trial welding is qualified. When welding, check the lap width of the diaphragm again and ensure that the lap area is clean, free of foreign matter, or anything else that may also affect the quality of the weld. Adjust the various technical parameters of the welding machine and weld in a certain order. During operation, the operator needs to follow the operation of the welding machine at all times under the protection of the safety rope or rope ladder, and fine-tune the technical parameters of the welding machine in time, so that the whole process of the welding machine is in operation state and the weld quality is guaranteed. The quality of the two films and one cloth welds in the splicing is the splicing juncture. In construction, it is especially necessary to strengthen the joint inspection. The inspection methods are: 1. Visual inspection: After the two films and one cloth are welded in the river, check whether there are any leaks, whether the joints are burned, whether there are folds, whether the splicing is uniform, etc. 2. On-site leak detection. There are two types of on-site leakage detection: 1) Inflation method: The weld is double strip, There is a cavity of about 10mm between the two bars, the two ends of the section to be tested are sealed, inserted into the air needle, inflated to 0105mpa - 0120mpa, watch 015min, check the vacuum meter, if the air pressure does not drop, the confession does not leak, the weld passes, otherwise find the reason to repair it in time. 2) water filling method: the weld is double, leaving about between the two 10mm cavity, seal one end of the section to be tested, insert a water needle at the other end, and fill it with water to 0105mpa - 0120mpa. If no water leaks from the hole cavity, the confession weld passes, otherwise find the cause and repair it in time. The two film and one cloth water filling method has the following advantages over the inflatable method: it is good in appearance, and it is easy to detect problems in time. The project uses the water filling method to check the quality of the welds. After passing the self-inspection, it is submitted to the supervision unit, the quality inspection department and Party A for joint sampling inspection, and section-by-section certification visas are implemented. water filling detection, The next procedure can not be carried out until the acceptance has passed.
