I. Introduction overall rain check wells using injection molding, the well base and the wellbore composition material are polymer resin based materials, resin materials account for more than 80%. Wellbore injection molded using a single wellbore, but also by a plurality of injection monomer combination. With heightening heightening accessories can more easily to the ground. 2 Product Specifications Model:. YBSJC-100 Material: polymer resin three product applications are used in lawns and residential side street catchment, lower connection rainwater collection wells seat four characteristics of a product, good corrosion resistance, acid and alkali. , anti-aging, long service life. 2, using high-performance rubber seals flexible connection, flexible, good sealing performance, can effectively prevent water leakage, protect groundwater sources. 3, with the well pipe joint motion, uniform settlement, to solve the problem of uneven settlement of traditional brick and plastic pipe connections well produced. 4, smooth wall smooth, easy dirt retention, good drainage performance. 5, light weight, easy to transport, construction throughout the day regardless of the weather constraints, split and combination, safe and convenient construction, low construction cost.
