Geomembrane construction important surface poor base quality base quality directly affects the waterproof efficiency of plastic geomembrane plastic geomembrane as initial support (shotcrete, continuous wall) laying requires that the base surface should be very flat effortless and meet the ideal requirements according to engineering practice experience mention: Laying plastic geomembrane base should be flat without sharp objects base flatness should meet the D / L=1/6 ~ 1/10 requirements formula: D-- initial supporting base adjacent two convexes recess depth L-- distance between initial supporting base adjacent two convexes click ID to consult more questions

Zhoutou reservoir dam is core-wall dam: // h, taking the bedrock curtain grouting for vertical seepage-proofing. According to the safety argument and analysis this time of Zhoutou dam: // h, but because of the collapse .hiphotos. Specific location and project quantity see design drawing, originally added the anti-seepage sloping core.97m) .0m elevation (higher than maximum flood level of 0, up to contact surface grouting, in order to solve the leakage weakness plane and dam foundation leakage caused by repeated landslide of dam, in order to solve the upper anti-seepage problem. The top sloping core part use composite geomembrane bedding seepage-proofing.

First, the construction of the ground: 1, cleaning the ground and pavement 2-3 cm thick squeeze Schomburg plate 2, according to need to tailor the electrothermal film, side by side pavement electrothermal film 3, parallel connection electric heating film (according to the standard of construction connection drawings connected, single electrothermal membrane does not exceed 10 meters) 4, using special tool will be special pinch the child with the electrothermal film metal loading bar is firm in connection and connect the wire 5, with insulation mortar will connect parts of the overall package, fully waterproof insulation. 6. The air switch should be configurated according to the general power, and connect the thermostat, the sensor, the sensor probe into the ground is the most easy to heat area to avoid overheating of the heating film. 7. The sensor added the casing and the drive pipe would be cut in the head of the sensor. To paste it on the electric thermal film with the help of the insulating plaster. 8. Make a comprehensive review of the 9 with waterproof cloth will electrothermal film package (cement construction) or pavement non-woven (floor or the floor sheet construction) 10, start thermostat measured temperature rise 11, pavement geothermal plastics net, pour cement mortar, inlaid tiles (cement construction), shop floor (floor construction) 12, the construction is completed

Therefore, the service life period of composite geomembrane is sufficient to meet the service life period of the dam seepage-proof requirement., Ethylene / vinyl acetate copolymer (EVA), mainly including polyvinyl chloride (PVC) .hiphotos.2m added stabilizer polyethylene film, whose years of working is 30 to 40 years under sewage conditions, with small proportion, low temperature resistance, corrosion resistance, good extensibility. Composite geomembrane is a kind of soil engineering impermeable material taking plastic film as a substrate, and combined with non-woven fabrics. The service life period of geomembrane, good anti-frost?property.

Yes, geomembranes can be used in rainwater harvesting and storage systems. Geomembranes are impermeable liners that can prevent water from seeping into the ground, making them ideal for creating a barrier to collect and store rainwater. They can be used to line collection surfaces such as ponds, tanks, or reservoirs, ensuring the rainwater is effectively stored and protected from seepage.

Yes, geomembranes can indeed be used in road and bridge construction. They are often employed as a barrier or liner material to prevent the infiltration of water, gases, or contaminants into the underlying soil or structure. Geomembranes provide excellent protection against corrosion and can enhance the longevity of roads and bridges by preventing damage from moisture and chemical exposure. Additionally, they can also aid in slope stabilization and erosion control, making them a versatile and valuable component in infrastructure development.

It can only be tested with the help of schematic circuit of the membrane switch. It is usually the shift knob that goes wrong. If there is no schematic circuit, you can only find out the problem by yourself. Membrane switch is actually a trigger signal to the IC. It is mostly a line or an array. This problem is rather obvious and easy to find out, but generally when membrane switch goes wrong, there is no way to repair but switch to a new one.
