This long-term resistance to stress not only be able to withstand the weight of its load of concrete floor, can withstand the inevitable during the construction period and the impact of external pressures, such as vehicles, trampling workers and pouring of concrete momentum and so on (30 cm of soil must cover Layer circumstances). Long-term bottom is not deformed, thus maintaining the original displacement. PVC drainage board in terms of drainage, the economic benefits than the traditional stone, ceramic filter layer drainage and other superior and reliable. Drainage Board effective solution to the traditional landscape mode (such as the use pebbles, shells, ceramic, etc. as a filtration material) does not prevent the plant root system damaging the surface, not insulation, load and other shortcomings; along with water, drainage, ventilation , thermal insulation and anti-thorn five prominent features; a large area up to water, electricity, sound and other effects, effectively slow "thermal effect" of the city. PVC drainage board has the following points: 1, environmental protection: the use of environmentally friendly PVC material, do not pollute the environment. 2. Drainage: boss clearance space, drainage capacity far better than traditional gravel, ceramic. 3, compression: a special process, the top boss thicken, making compression performance stronger. 4. Space: Product thickness is very thin, significant savings in the building space. 5, blocking root: The hot-melt welding, so plant roots can not penetrate the drainage board, a protective waterproof layer. 6, anti-corrosion: the natural environment and general industrial environment of acid, alkali, salt not reacted with PVC material products, so as to achieve the preservative effect. 7, durable: the stable performance of PVC production, product performance and lasting stability, service life more than a century. Tensile strength: 100KG / M Elongation: 5 (%) Tear strength: 200KG / M impermeability: 100% PVC drainage board is made of high density PVC material extrusion molding, it leverages the large PVC material density material properties large, amorphous structure strength made of cross drainage board. It is the use of cross support column and top post intermediate additional patented design, the use of large flat top and middle column are arranged in the form of support columns, to ensure complete soil cover does not sag after geotextiles, leaving enough space for smooth drainage. At the same time the size of eight cross support pillar reinforcement, which greatly increases its compressive strength. The product is a fixed width, length can be customized according to the needs, to facilitate the construction and auxiliary set, after the formation of auxiliary set to complete a new waterproof layer and every root layer. PVC drainage board application landscape / Green Engineering: garage roof greening, roof garden, soccer fields, golf courses, and other green engineering and construction projects: building the basis of the upper or ground floor, basement and outside walls, roof and insulation and other impermeable PVC drain membrane advantages 1, auxiliary Waterproof drainage membrane unpaved access thanks to an adhesive-type hot form, thereby forming a new waterproof layer, that have secondary drainage waterproof 2, every root function in general waterproofing membrane does not have a root partition function, and PVC membrane due to the high density, with a strong root partition can be adjusted according to the requirements of every root, film thickness, to every root effect. 3, both hot bonding can take due PVC material is non-crystalline structure, the use of special glue can effectively destroy the surface structure of the material so that the two-layered film can be effectively fused together, a watertight compartment root function. It may take the form of mechanical hot. 4, high strength PVC material web compressive strength, its compressive strength is equal to 1.5 times the thickness of the membrane PS, 2.5 times the HDPE material. 5, anti collapse design all have adopted anti-collapse of the drainage coil design, which thanks to the top of the column intermediate support structure, geotextile not sag after casing to ensure adequate drainage space. PVC drain 1 basement side wall construction technology, construction wall to solid smooth, clean sand and sharp protrusions can not play, hollowing, potholes and other phenomena. 2, the construction walls are finished Adhesive drainage board. 3, with the riveting bolt fixed drain. 4, in a uniform coating surface drainage board interface emulsion. 5, the drainage board whitewash mortar and embedded network gingham. 6, the second track cement powder will mesh covered with mortar smooth. PVC drain underground garage floor waterproof construction technology 1. floor should be cleaned up before construction garage floor cleaning is completed, construction of the base surface should be smooth, firm, can not have from the sand, sharp projections, hollowing, potholes and other phenomena. 2. Coil auxiliary set 1, will roll on the floor built by a certain order of laying around, lap, 2, left and right around the web and has a size which overlap the column, the column should be set into the big small lap ride next column. 3, in order to prevent leakage or construction may be coated with glue or web slide a certain distance in the overlapping edge with cement pouring cement point is fixed. 3. pouring 1, with C20 fine aggregate concrete pouring on the web, with a straight bar disappearing, 1-2cm above the subsequent construction in order to be cured. 2, after the concrete has set steel bar, pouring concrete surface, set into the floor drains, sumps. 4. Note 1, laying sheet must complete the lap and fixed in leakproof slurry. 2, should be laid to wear soft-soled or no spikes to prevent puncture membrane. 3, laying avoid using heavy vehicles traveling on the web directly to prevent the material being crushed or crushed. 4, pay attention to material fire. PVC material properties of PVC plastic features, if not long-term exposure to ultraviolet light, the next five years in the soil does not age. It does not change by temperature, bacteria effect, water vapor, and PVC material compared to other plastic materials have a greater advantage, PS material has a certain strength, but the drawback is brittle, easily torn, especially in the construction case damaged in serious condition. HDPE material toughness, but the strength is not enough to reach a certain intensity must increase the film thickness, the high cost. To reduce costs, the existing HDPE drainage material extensive use of recycled materials in production, quality instability affect life expectancy. The PVC material is characterized by a modified way through the material, increasing strength, resistance strong, tenacious, not easy to tear out circumstances under construction cracked, damaged, the same intensity, the thickness of the film is much thinner than HDPE, new material Production is relatively inexpensive. PVC drain construction and technical acceptance grassroots planning bomb line socket laying drainage board geotextile Laying flowchart mechanical casing PVC drain PVC drain Advantages 1, PVC drainage board is based on the principles of mechanics using the support columns plus intermediate head column structure, By combining the high and low post, the latter does not sag geotextile casing to ensure adequate drainage space. Strong resistance root, 2, PVC drain due to the large density, with a strong root partition can be adjusted according to the requirements of every root thickness of the film to achieve the effect of every root, and tear. 3, compressive strength, PVC drain compressive strength, its compressive strength is equal to 1.5 times the thickness of the membrane PS, 2.5 times the HDPE material. H20 Drainage Board 0.7mmPVC material thickness compressive strength 300kpa above, and the same thickness compressive strength of PS and HDPE material only 150kpa about. Because of its unique design Strengthening rib structure generally flattened cars in any of the above is not straight support column. This is the other PS and HDPE materials can not be achieved. 4, both hot bonding can take, because the PVC material is non-crystalline structure, the use of special glue can effectively destroy the surface structure of the material so that the two-layered film can effectively fused together, so that the construction after the completion of a watertight compartment root function . Also available mechanical hot pick. 5, the second waterproof, drainage membrane unpaved access thanks to an adhesive or hot form, thereby forming a new waterproof layer, that have secondary drainage waterproof.
