| 排水用检查井是城市地下排水排污管道系统中连接管道的井状构筑物，设置在管道交汇处、转弯处、管径或坡度改变处、跌水的地方或直线管段上每隔一定距离处，是管网系统检查和疏通、防止管道堵塞的必要设施，在管网系统不可或缺。 Drainage inspection wells are well-shaped structures connecting pipelines in urban underground drainage and sewage pipeline system. They are set at the intersection of pipelines, turning points, change of pipe diameter or gradient, drop places or straight line pipelines at a certain distance. They are necessary facilities for inspection and dredging of pipeline system and preventing pipeline blockage. They are indispensable in pipeline network system. 排水用塑料检查井指采用高分子材料制成，用于排水排污的检查井。它属于预制井，替代传统的砖砌检查井，通常由井盖、井筒、偏置收口、井座以及相关配件组合而成。井座是塑料检查井的核心部件。 Plastic inspection wells for drainage refer to inspection wells made of polymer materials for drainage and sewage discharge. It belongs to prefabricated wells and replaces the traditional brick inspection wells. It is usually composed of well cap, wellbore, offset receptacle, wellbore and related accessories. Wellbore is the core component of plastic inspection wells. |
