| 塑料检查井的组成 Composition of plastic inspection wells 检查井由井座、井筒和井盖及其配件组成。 The inspection wells are composed of wellbore, wellbore, covers and their accessories. 1、井座材料一般以聚氯乙烯（PVC）、聚乙烯（PE）、聚丙烯（PP）等高分子树脂为主； 1. Wellbore materials are mainly polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) and other macromolecule resins. 2、井筒一般宜采用成品埋地塑料管材，其管材需符合下列要求： 2. It is generally advisable to use finished buried plastic pipes in wellbore, which should meet the following requirements: （1）井筒管材的环刚度应大于等于4KN/m2; (1) Ring stiffness of wellbore pipe should be greater than or equal to 4KN/m2; （2）井筒材料应符合GB/T 10002.3、GB/T 18477.1、GB/T 19472.2和EN 1398.1(外径系列)标准的要求。 (2) Wellbore materials shall meet the requirements of GB/T 10002.3, GB/T 18477.1, GB/T 19472.2 and EN 1398.1 (outer diameter series). 3、井盖材料主要以PVC塑料树脂、热塑性树脂（PE、PP、ABS等）和碳酸钙、粉煤灰、矿渣为主要原料，再添加一定的助剂。 3. The main materials of well cover are PVC plastic resin, thermoplastic resin (PE, PP, ABS, etc.) and www.tongfengguan.com.cn www.haozhengkj.com www.gangmoju.cn www.machine-com.com www.shangjindesign.com www.bdkscm.com calcium carbonate, fly ash and slag, and some additives are added. |
