The grid plate is a rectangular grid plate with firm welding points and plate shape surface by pressing twisted square steel with certain spacing into the side force flat steel. The flat steel bears the load, and the cross bar (twisting direction) plays the role of connection. The direction of the flat steel represents the length direction of the grid plate, and the direction of the cross bar represents the width direction of the grid plate; The grid plate has the advantages of light weight, high strength, large bearing capacity, economical materials, ventilation and light transmission, modern style, beautiful appearance, anti-skid safety, easy cleaning, simple installation and durability.
Burial integration adopts internationally advanced biological treatment process to remove BOD5 Combined with COD and NH3-N, the buried integrated sewage treatment equipment has the advantages of stable and reliable technical performance, good treatment effect, less investment, less land occupation, convenient maintenance, etc. It is mainly applicable to domestic sewage and similar industrial waste water in residential areas, hotels, docks, airports, shopping malls, sanatoriums, schools, factories and mines and other industries.
Water stop rubber strip is the general name of putty type water stop strip and product type water stop strip with water expansion performance. Water swelling rubber is a unique new rubber product. It not only has the performance of ordinary rubber products, but also can expand itself when encountering water. It is a new type of waterproof material, with water stop and waterproof effect more reliable than ordinary rubber. Water swelling rubber has more outstanding characteristics and advantages than Puzhaotong rubber. This kind of rubber will produce 2-3 times of expansion deformation after encountering water, and fill all irregular surfaces, cavities and gaps of the joints. At the same time, it will generate huge contact pressure to completely prevent leakage. When the joint or construction joint is displaced, causing the gap to exceed the elastic range of the material, the ordinary rubber water stop material will lose its water stop function. The material can also stop water by absorbing water and expanding. The use of water swellable rubber as leak stopping and sealing material can not only save the amount of water, but also eliminate the characteristics of elastic fatigue caused by excessive compression of general elastic materials, making the waterproof effect more reliable.
Geotextiles have the functions of * * filtration, drainage, isolation, reinforcement and protection, and are characterized by light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. Geotextiles are widely used in water conservancy, electric power, mine, highway, railway and other geotechnical projects
Filter press is a commonly used solid-liquid separation equipment. It was used in chemical production at the beginning of the 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramics and environmental protection industries. The filter press is a kind of mechanical equipment that uses a special filter medium to exert a certain pressure on the object to make the liquid seep out.
