塑料检查井是指构成检查井的主要井座部分采用高分子树脂材料一次性注塑成型。根据接管数和角度不同有起始井座、直通井座、45度弯头井座、三通井座、四通井座等。为了适应各种排水状况，塑料检查井同时配套有变径接头、汇流接头、井筒多接头等与之配套的塑料一体注塑成型配件。以保障整个排水系统的流畅和密封性。
Plastic inspection well refers to that the main well seat part of inspection well is made of polymer resin material by one-time injection molding. According to the number and angle of connecting pipes, there are initial well seat, through well seat, 45 degree elbow well seat, three-way well seat, four-way well seat, etc. In order to adapt to various drainage conditions, the plastic inspection well is equipped with variable diameter joint, confluence joint, shaft multi joint and other plastic integrated injection molding accessories. To ensure the smoothness and tightness of the whole drainage system.
塑料检查井以高分子树脂为原料，采用组合结构，一般是由检查井井座、井筒、井盖等组成，分为污（废）水检查井和雨水检查井。污水井一般设有流槽，便于污物排放顺畅，雨水井（一般设有供泥砂沉淀的沉泥室）以方便后期的清理和维护。
The plastic inspection well is made of high polymer resin and combined structure, which is generally composed of inspection well seat, well bore and well cover, and is divided into sewage (waste) water inspection well and rainwater inspection well. Generally, the sewage well is equipped with a flow channel to facilitate the smooth discharge of pollutants, and the rainwater well (generally equipped with a settling chamber for settling mud and sand) is convenient for later cleaning and maintenance.
