1、Xuchang Drainage Board ManufacturerWelding Technology
①Weld overlap width: 80~100mm; natural wrinkles on flat and vertical surfaces are:5%~8%; reserved expansion amount:3%~5%; residual amount of scrap:2%~5%.KKolps33378
②Hot melt welding working temperature280~300℃; travel speed2~3m/min; welding form is double welding seam.
③Repair method for damaged areas: Cut materials of the same specification, hot melt adhesive bonding, polyethylene glue sealing.
④No imitation fabric connection at the weld seam, adopt mechanical sewing.
⑤Sealing and waterproofing of underwater pipe openings use GB rubber water stop strips for sealing, metal wrapping and anti-corrosion treatment.
2、Laying Technology156-2152-1000 Manager Shao
①The laying and unfolding direction of composite geomembranes is from E to W or from W to E, completing the height of the water-blocking walls on both sides in each laying length.
②Laying sequence, advancing from the channel axis line to the S and N sides.
③Construction procedure: First, make a mortar protective layer ( 20-30mm) on the lake bottom composite geomembrane, followed by sticking to the vertical water-blocking wall.156-2152-1000 Manager Shao
④The bonding process of the composite geomembrane and the water-blocking wall: Apply adhesive on the bonding surface of the composite geomembrane and the wall, dry and rest for about 5 minutes, then proceed with bonding, pressing, and leveling. The adhesive is made of asphalt latex paint, cement, and water mixed together. After bonding, nail and secure above the water line, and perform waterproofing and anti-corrosion treatment.

1. Before laying HDPE geomembrane, ensure corresponding qualified acceptance documents from civil engineering.
2. Before cutting the HDPE geomembrane, its relevant dimensions should be accurately measured, then

cut according to actual measurements. It is generally not advisable to cut according to illustrated dimensions, and each piece should be numbered and recorded in a dedicated form.
3. When laying HDPE geomembrane, strive to minimize welds, saving raw materials as much as possible without compromising quality. This also makes it easier to ensure qualityXuchang Drainage Board Manufacturer.KKolps33378
4. The overlap width between the seams of the membranes should generally not be less than10cm, and the welding seam arrangement direction should usually be parallel to the steep slope, i.e., arranged along the slope direction.156-2152-1000 Manager Shao
5. Typically, at corners and irregular sections, the length of the seams should be minimized. Unless specified otherwise, on slopes greater than1:6, within 1.5 meters from the top of the slope or stress concentration areas,Xuchang Drainage Board Manufacturer should avoid setting welds as much as possible.
6. During the laying of HDPE geomembrane, avoid generating artificial wrinkles. In lower temperatures, it should be pulled tight and laid flat.
7. After laying the HDPE geomembrane, minimize walking on the membrane surface, moving tools, etc. Any objects that may harm the impermeable membrane should not be placed on or carried on the membrane to avoid accidental damage.
