The geotechnical membrane technology of urban construction?
- The welding construction must be synchronized with the geomembrane one after another. The slope geomembrane is laied from up to down in a whole and cannot be splited joint. The upper left shoulder slope and anchorage capacity, and the lower end to the bottom of the pit left head slope root distance of not less than 1.8m, membrane end alignment with hot wedge welder connection. The slope shoulder is welded with extrusion welding. The seam should try to avoid the corner groove in the corner, and try to minimize the irregular shape. If it can not avoid the corner ditch, you must use a squeeze welding machine welding seam. In the crossed welded seams, it must be used to weld the welding machine welding. The length of welding shall not less than 20cm. Before welding, the welding seam should be trimmed to the exposed welding seam, and then the welding machine can be used to fill up the welding machine with the hand wheel.s
how thickness of the geomembrane is paving in loach pond. .
- first, I will not say that when paving geomembrane the ground should be compaction, even if the ground is very soft, under the hydraulic pressure, there is no gap between the membrane and land, what's more, how much is the geomembrane national standard tensile strength? How much is the bursting strength? how much is the Elongation? If a small loach can drill the it broken, then we can know that how poor the geomembrane quality is, of course, if you are specializing in geomembrane cultivation, black 0.35 national standard geomembrane is generally recommended, the quality is out of question in three to five years.s

HDPE construction process of HDPE geomembrane
- Clear substances that have hidden danger of puncture on bare base surface, completion and acceptance, etc. Acceptance of construction quality. ③Repair methods of damaged parts; welding form is double bead. 5. Recommendation 1, the maximum design water level. Ther is nooil pollution at joint. Planned duration is 3 days. Substances that can cause harm to anti-seepage film and constructors related to water proof materials. First, cut HDPE geomembrane into trumpet-shaped pipe sleeve according to the diameter of leachate in dam. 50×4m, do not wipe in hands. Bond is made up of asphalt latex paint, otherwise, set aside telescopic deformation caused by changes of temperature. ②Operating temperature of sweat soldering is 280 -300℃. ②Water resistance of bridge foundation. Weld after treatment. 4, Need latitudinal splicing so as not to damage the membrane surface. Dew: 5% to 8%.s
The concept of HDPE geomembrane
- PE has excellent resistance to most living goods and industrial chemicals, relatively large use temperature range (-60---+60) and long service life (50 years). It is aging-resistant and can be used in artificial lake seepage proof.s
