Product Description

Tri-dimension composite genet for drainage is a new type of geosynthetics.

Its made of atri-dimension geonet coated with geotextile on both sides. Network core consists of a tri-dimension

thick vertical rib, and a rip on top and bottom .

It can drain underground water quickly, also there is a protection system,which can block the capillary water under high load. At the same time, it can also reinforce and isolate of foundation.

 

Product Uses

  

1,Landfill drainage;

2, Roadbed and road drainage; 

3,Railway drainage, tunnel drainage, underground structure drainage. 
4,The retaining back wall drainage, 

5,gardens and sports grounds drainage

 

 

 

Functions

Excellent drainage function, can bear long time hige press load

High tensile and shear strength

Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity

Tri-dimension composite geonet for drainage can bear more than kpa compression load

Its anti-compression capacity is much larger than common geonet for drainage.

Q:How to use geomembrane to plant lotus root?
When planting the lotus root, both geomembrane and composite geomembrane can be used to prevent seepage and resist root. The site on which the geomembrane or composite geo-membrane is laid should be properly treated. Before laying those materials, the site should be levelled and pressed firmly without sharp stones and branches on it. For example, if mountainous ground is uneven, loess should be laid to level it. When the geomembrane is laid, it is strictly prohibited to move machinery on it. Workers that lay the geomembrane should wear flat shoes to walk on it. After the geomembrane is laid, soil of certain thickness needs to be backfilled on the geomembrane to protect it.especially in the area above the water around the lotus pool to prevent the sun exposure and the aging of geomembrane.
Q:Construction technology of geomembrane:
Notes for geomembrane joints: (1) the joint treatment of the geomembrane is the key process of construction, which directly affects the service life of the project. Indicated by quality test, hot weiding is an ideal way. (special adhesive is also available). Heat welding method is heating the surface which is connected with the PE geomembrane, the surface melting, and then through the pressure to merge them into one, (2) Geomembrane shall be paved along a certain direction, on both sides of the geomembrane should be reserved for certain PE membrane and PET membrane bonding layer.While paving, we should adjust the tendency of geomembrane of each unit, in order to bring convenience to two units geomembrane welding. (3) Press geomembrane with sand bags to prevent wind after pavement, edge joints requires no dirt, moisture, dust, etc.. (4) before welding, adjust the joint at two sides of PE membrane, jointing them with broadband, and making them smooth, and no wrinkle. (5) When welding, it is better to have a technical personnel of certain experience, and use a special welding machine for welding. Adjust the temperature and speed, (can also use adhesive to bond). According to many years of practice, it is proved that the thickness of the geomembrane is not less than 0.25mm, because too thin is possible to produce porosity, and it is easy to be damaged in the construction to reduce the seepage control effect. During the construction of geomembrane, we should pay special attention that the pavement should not be too tight, shouldn't wrinkle, and the jointing should be firm. We should construct strictly according to the technical specifications, checking five quality clearance comprising preparation, paving, splicing joints, testing and backfill.
Q:What are the techniques of foam concrete?
With unique foam excitation technique, coal ash and other waste materials are mixed together in a scientific proportion, then they will become gold bricks—high-performance building blocks which can float on water with many advantages of lightweight, environmental protection, energy-saving and thermal insulation after going through many techniques of compulsory stirring, activation, foaming, output, casting molding. Special foaming agent is composed of several chemical raw materials in a certain proportion that are easy to buy. It will become light after foaming which is much more effective than that of most foaming agents sold in the market, but the price of it is 50% lower than that of most foaming agents sold in the market. High efficient curing agent is composed of several chemical raw materials in a certain proportion that are easy to buy, which greatly reduces cement quantity and cost. It has advantages of high strength and light weight, and enables non-autoclaved blocks (bricks) to reach and exceed the required strength of steam-cured blocks; MS innovative forming non-autoclaved blocks new molding technology, moulds can arbitrarily change the size of blocks in order to adapt to fit around the block sizes that walls need, which reduce the cost of moulds, and are convenient.
Q:Which one should be used for dam protection, geomembrane or wire box?
Wire box, of course. It has good protection effect and can prevent the dam from landslide, water loss and soil erosion.
Q:which is good for the eyes, Matte stick membrane or high permeability stick membrane
High permeable membrane, compared with the matte film, is good for the eyes , but it usually need to pay attention when using the cell phone, the eyes can not said that it won't be hurt with no film or pasting other kinds of film, pay attention to the time and the way of playing mobile phone, I think it is still very good.
Q:Is far infrared ray electrothermal film good?
Far infrared electric heating film is very good. You can try it.
Q:What types of work does geomembrane welding belong to?
Excavator
Q:Geomembrane snz/ pvc-12-400-0.35 model
(there is no manufacturer can produce 12m wide geomembrane at present) if it is SN/PVC-1, using 400g/ ㎡ polyester staple fiber geotextile and 0.35,another possibility is that your product model is wrong At the same time, according to national standard GB/T17642-2008. Combine 35mm thick PVC geomembrane together, using 400g/㎡ polyester staple fiber geotextile and 0. If this is geotechnical material used for seepage-proofing in the projects,
Q:What are the prospects of electrothermal film?
Electrothermal film has been in the market for at least ten years. Currently the biggest problem is the large power consumption, even if you can cover the electric charge,original home wire diameters restrict the use of high-power electrical appliances. Another problem is power attenuation, the other problem is breaker tripping caused by electric leakage.
Q:what's the focus of construction quality control for composite geomembrane?
detect all the welding lines with aerate methods, wrinkles or not, cracks, deterioration or degradation of other materials .5min, construction quality inspection mainly depends on sampling .20MPa.05MPa ~ 0, under construction, we should choose a test specimen out of every 1000m2, the focus of geomembrane construction quality control include the quality control of importing raw materials, holes, qualified welding line and gas needle. 3, defects and uneven thickness, leaving about 10cm cavity between the two cavities, avoid the sun, inflated to 0, to minimize the number of loading and unloading, the scene extracting a total of 461 specimens of weld group. 1. The construction process control is mainly to strengthen the geomembrane weld quality testing. 2. (1) visual method, it requires strength not less than 90% of the base material, whether iron loss seams, sealed at both ends of the test section. The whole project uses a total of geomembrane approximately 461100m2. (2) leak detection: After welding geomembrane, observe whether the bobble, even if stitching, etc., contemplation 0. raw material quality control approach geomembrane must have a certificate provided by the manufacturer. Geomembrane doesn't allow any needle eye, otherwise seams quality will be substandard, not leak, or to find out the reasons and timely repair, for the tensile strength test, tensile strength test, and the specimen fracture can not be broken at the seams, after testing pass rate is 100% , features and performance indicators and operating instructions, detection methods are visual inspection and leak detection, finished construction quality inspection. During transport, and after the arrival, it should be kept carefully, such as no pressure drop, construction process control; geotextile are not allowed to crack, weld double bar, weld quality standards
