Company Name: Yancheng Jinyang Road Equipment Co., Ltd. ?? Company Address: Jiangsu Jianhu private industrial park on the 4th Road No. 69 ?? Company Profile:?? The company's products are mainly raw materials used in unsaturated polyester resins, has excellent impact strength and resistance to corrosion, aging, than similar products (such as cast iron, cement manhole cover) have better technical performance and practicality. Widely used in urban road manhole cover, water grate, communications, water, gas, electricity, chemical industry base and other pipeline manhole covers. Products are designed, light weight, coloring, etc., to the installation, maintenance, identification has brought great convenience, but because the product no recycling value, a fundamental solution to the theft to pedestrians because of the danger caused by the vehicle. Composite covers preparatory work before installation. Yancheng Jinyang Road Equipment Co., Ltd. in order to meet market demand, the gradual development of a multi-standard, multi-species products, such as polymer water meter covers, polymer composite circular inspection covers, municipal wells, water wells, sewage covers, inspection covers, manhole cover, valve covers, power telecommunications manhole covers, water wells; and high quality performance, high-quality service has won the trust of customers, becoming municipal, factories, schools, community, power, telecommunications, real estate, squares, water, economy Preferred Applications Product Development and other departments, and has broad prospects for development, products sold throughout the country. ?????? Composite covers before installation to make adequate preparations to avoid unexpected situations arise during construction. To improve the efficiency of construction of major construction unit, the following detailed overview of the preparatory work before the composite covers installation: 1, before composite covers installation, first according to requirements, bearing grade, logos, etc., confirm that you want to install Jingquan, covers, so loaded wrong, resulting in unnecessary losses. 2, ultra-high molecular composite manhole cover, is the use of polymer composite materials, through advanced parallel twin-screw plastics mixed with direct injection molding after training, Manhole designed taking into account its use of features and material costs, and covers Manhole coupling parts Manhole thickness of only 20mm, so when installation Manhole, urged: covers the mouth and the wellhead must be the same size, the well mouth and wellhead circle must be aligned, non Manhole shift, causing its local vacant, covers bearing the weight when so Manhole support side pressure off, covers sinking, you can not use, or cause traffic accidents, so special emphasis on the installation Manhole, if found Manhole and wellhead offset phenomenon, should promptly corrected; after Manhole aligned with the wellhead, covered wells, 1 cm thick sand on the tile covers, Manhole around the use of layering pressed, after a fixed level, then pour concrete, the concrete and Manhole surface, and the road flat Qi. After concreting over, open wells, clean up the surface and covers the side seam of sand fall into the covers, and then covered with covers, covers placed around the stop sign, until the concrete curing, square to allow construction of concrete or asphalt pavement. Polymer composite circular inspection covers heavy Φ800 Features 1, high strength: Magnesite inspection with high compressive, flexural, impact strength, toughness. The product will be crushed and damaged covers the phenomenon of long-term use, can completely eliminate the occurrence of "urban black hole" of the accident. 2, beautiful appearance: Magnesite inspection covers surface pattern design beautiful, bright colors adjustable, beautify the urban environment. 3, easy to use, light weight: only about one-third the weight of cast iron, easy to transport, installation, repair, greatly reducing the labor intensity. 4, security: Magnesite inspection covers no recycling value, natural anti-theft; according to customer needs and has a locking structure, to achieve the well property theft. 5, weather resistance: Magnesite inspection covers by scientific formula, advanced technology, improve technology and equipment so that the product can be used normally at -50 ℃ ~ + 300 ℃ environment. 6, acid, corrosion resistance, abrasion resistance, rolling vehicles, long service life.
