Advantages: 1, save resources and protect the land: the use of polymer resin as raw materials, instead of traditional brick, masonry cement well as raw materials, reduce the consumption of energy and farmland, saving valuable clay resources; 2, to protect the environment efficient drainage: each nozzle connections are made of a flexible connection, good sealing performance, the complete elimination of rain water seepage, leakage, prevent secondary pollution of groundwater. The smooth wall, low roughness coefficient, strong performance through the water, drain efficiency is about twice that of conventional manhole; 3, easy transportation and installation: injection-well, well base and wellbore isolation, site assembly, you can save shipping costs ; but also shorten the construction period, the construction period is 1/10 of the traditional inspection wells; 4, durable: anti-aging of polymer materials, resistant to degradation of characteristics determine the product's long life; my company's unique Manhole stiffener designed to increase the body well and soil friction, achieve the anti-settling and anti-floating uneven results; 5, anti-leakage: the overall well a molding, hot-melt and flexible support base between manholes and drainage pipe plug connection, uneven settlement of pipe base material and withstand thermal expansion and contraction of adaptability, which can effectively prevent leakage; 6, fit and strong: according to the height of the actual project needs, the well finished seat insert Pipe (Pipe, corrugated pipe, steel pipe, glass pipe may be). Shaft height can be adjusted and the cylinder drilling, adjust the direction, to meet all the needs of the project installation. 7, excellent economic performance: lower total cost, it can be recycled use, cost and lower than the reinforced concrete well 1/3. Zhengzhou-source plastic manholes, all one-time injection molding HDPE plastic inspection wells, wellbore socket 360-degree ring bearer platform, and each socket using ring ribs and wellbore using a mesh ribs, using a flexible bearing plug-in connection. Asia Source HDPE plastic manholes surface smooth and clean, novel and unique structure to overcome the instability assembly and sealing manholes poor performance shortcomings, but also to make the process simple and rough rotational manholes, wellbore intensity difference deficiencies. Zhengzhou City-source Plastic Co., Ltd. is the largest and most professional in Central disposable injection molded plastic manholes Supplier Website: www.yayuanjcj.com www.yysj88.com
