Product Description

The ideal slope for a plastic lined dam is a 3:1 gradient, however if design constraints require steeper gradients, installation can still be achieved, although additional safety requirements would need to be considered. Shandong Tianhai can supply ladders welded to the liner surface, alternatively you can opt for one of the options below, and soil cover the top perimetre of the dam, allowing maximum safety and aesthetics. In preparation of the dam surface (sub grade) ready for the liner installation, some earth works must be completed.This should bring the sub grade to a level that is a dry, smooth, firm and unyielding foundation, without abrupt elevation changes, voids, cracks, or standing water, free from vegetation, sharp edged rocks, stones, sticks, construction debris and other foreign debris. It is recommended to have the sub grade flat drum rolled just prior to the liner installation.

How to Stop Tree Roots. Installing a root barrier around a tree is a landscape control that helps stop the roots from damaging sidewalks, or other landscape areas. Take the time to plan your landscape before planting so you can place a barrier into the soil early in the life of the tree. This will force the roots deeper, instead of having to cut through large, mature roots that may cause damage or death to the tree. Contact a tree professional before attempting to stop mature tree roots that are close to the soil surface.

HDPE geomembranes provide an impermeable barrier against solids and liquids. They exhibit excellent chemical and UV resistance. They used as the liner. (different thickness of distinction, different thickness and different price). production capacity: thickness:0.1 mm -3 mm, width: 1-8 meters. It is suitable for seepage control in special industries, and is widely used for aquaculture, seepage control, reservoirs or sewage treatment ponds.

Geomembrane is the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications. is made from polyethylene resins materials by blow molding process.According to the different raw materials, Geomembrane can be divided into HDPE Geomembrane,LDPE Geomembrane, EVA Geomembrane and PVC Geomembrane,etc.

HDPE Geomembrane is the low permeable synthetic membrane liner

HDPE has excellent physical property. Such as temperature adaptability, property of welding, bearing climate, anti-erosion,anti-crack and anti-puncture.As the leakage material,therefore Particularly suitable for the construction of underground,mining,landfill,sewage or dregs disposal.

Tinhy flat surface Hdpe Geomembrane is produced from high-grade white color hdpe geomembrane resin produced by foreign and domestic large petrochemical enterprises by three-layer pressing and plastic formation technology and double layer pressing and rolling technology. The company is the only enterprise that uses the two technologies to produce Geomembrane in the same industry. The company has plastic formation experience for more than twenty years, makes close cooperation with earthwork builder, makes continuous innovation, seeks perfection, and makes great efforts in providing the most reliable products to the customers.

The seam area shall be clean and dry, free of mud, moisture, dust, dirt, sand or debris and seam panels are overlapped properly for fusion welding. Seam surface area shall be abraded or grinded to rid of surface oxidation and tack weld for extrusion welding. Grinding is performed parallel to the seam and grinding marks shall not extend more than quarter inch outside the weld bead area. The Welding Technician shall ensure that wrinkles or fishmouths are minimized. During seaming, visual inspection and constant hand peel testing is practiced.

For all types of welding, the Installer Site Manager shall verify that the welding personnel are attentive and act professionally and all equipments are well maintained and functioning properly. Welding Technician must purge the Extruder machine of heat degraded extrudate for at least one minute prior to use. The surfaces to be welded are well abraded and clean.

Special detail fabricating areas such as sumps, pipe penetrations, concrete structures, fittings and accessories shall require Extrusion Weld process. Non-linear seams, roll ends, pipe penetrations, sumps, patches, corners or anywhere it is impractical to use a Fusion Welder are welded by Extrusion Weld method using an Extruder Resin or Extruder Rod Gun. This technique encompasses extruding molten resin between two geomembranes or at the edge of two overlapped geomembranes to effect a continuous bond. The extrudate rod or resin bead shall be made from similar type as the geomembrane.

Geomembrane liners are welded by Fusion Weld method using a self-propelled hot air or hot wedge welding machine. The welder creates a fusion weld by heating the overlapped liner surfaces, with a pair of pressure rollers pressing them together while in molten state to result in a permanent bond. Seam overlap shall be consistent with the requirements of the welding equipment being used. For fusion weld a 4 inch (100 mm) overlap is a common standard.

Generally, seams are oriented parallel to the direction of maximum slope. Seams are minimized in corners, odd-shaped geometric locations and outside corners. A seam is considered a separate entity if it is the principal attachment that joins two or more panels.

Sandbags that act as ballasts are sufficiently spaced and placed on geomembrane to prevent wind drift. Proper footwear that will not damage the geomembrane liners shall be worn by all parties allowed on the liner. Smoking is prohibited on the geomembrane. Heavy vehicles are not allowed directly on geomembrane. Protect and cover geomembrane in areas of heavy traffic, from moisture, from theft or over long storage periods.

Unroll geomembrane panels using methods that will not damage geomembrane and will protect underlying surface from damage by using a spreader beam and axle bar or a stationary unrolling stand or any other methods serving this purpose. The spreader beam is attached to the front end of the handling machinery. The spreader beam is constructed from steel I-beam or steel pipe and the axle bar is constructed of thick walled steel pipe. Spreader beam and axle bar shall be minimum one meter longer than the roll width.

Geomembrane liners are also used as floating covers or cappings onto wastes lagoons or sludge pits to reduce air pollution, foul smell and to control flies, rodents and pests. HDPE geomembrane floating covers may be utilized in tandem with a CDM biogas digester or methane gas collection facility to co-generate electricity or to flare.

The Application of HDPE geomembrane

1) Environmental protection sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .
2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).
3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).
4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).
5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).
6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.) .
