The composite high quality HDPE geomembrane technology has the advantages of short construction period, simple and convenient construction, low construction cost, good anti-seepage effect, etc. It is very suitable for small reservoirs to eliminate danger and strengthen.

The laying direction of the dam slope composite HDPE geomembrane factory price should be perpendicular to the direction of the dam axis, and the whole roll of material should be used from the dam shoulder to the dam foot to avoid horizontal joint connection. The composite geomembrane paving is set aside for the length of settlement deformation according to the design requirements, and the offset distance of the T-shaped joint at the connection part of the geomembrane of the warehouse is greater than 5c0m. Weld seam appearance inspection and repair welding After each weld seam is welded, the weld seam and appearance inspection are required: the weld seam should be smooth and beautiful, straight and smooth, the weld seam outline is obvious, it is in a transparent glass state, and there is no scald, air bubble, virtual welding Leak. If a problem is found, make a mark with a marker and immediately use a hot-melt air gun to repair the weld. Welding quality inspection. Before inspecting the inflation of the composite membrane, the start and end of the welding area of ​​the composite membrane should be no less than 5cm, baked with a hot-melt air gun until softened, and pasted tightly, so that the cavity of the welding area becomes a closed inflatable area. Inflatable inspection. When the air pressure in the cavity of the geomembrane reaches olZMp, the recording time is started and maintained for 180s. If there is no obvious drop in pressure, it is qualified. When the inflation inspection fails, timely inspection and repair welding.

Before the laying of the wholesale HDPE geomembrane, the manufacturer shall provide pre-job technical training and assessment to the construction personnel to ensure that the technical personnel are skilled in the construction. Strictly inspect the raw materials of the composite geomembrane according to the technical specifications, return the unqualified geomembrane, and strictly prohibit the unqualified composite geomembrane from going to the dam. Carry out construction and quality inspection in strict accordance with the construction process and construction plan approved by the supervision engineer. The construction personnel should wear flat-bottomed shoes or soft rubber-soled shoes for laying, so as to follow the laying and pressure, and the laying of the composite geomembrane should be coordinated with the laying of the protective layer. The project engineering department is responsible for the inspection and supervision, and finds the problem in a timely manner, eliminates the hidden quality problems in the budding state, and it is strictly forbidden to transfer to the next process for the failure of the previous process.
