检查井是用于雨污水排放管道的附属构筑物，是便于定期检查和疏通管道，防止管道堵塞的必要设施。
Inspection well is an auxiliary structure used for rainwater and sewage discharge pipeline, which is necessary for regular inspection and dredging of pipeline and prevention of pipeline blockage.
传统砖砌井的施工方法是用砖块砌筑井体，然后将管道插入井体并用水泥砂浆填补井管接口处，该工艺施工效率低，连接效果差会导致渗漏、泄露，需要不定期维护。为了响应节能减排的国策，近年来塑料检查井广泛用于市政、建筑小区、旧城改造、工矿企业建设等一系列工程，其采用高分子树脂为原料，在工厂进行预制（最关键的井座部保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 分采用一次注塑成型工艺），在工地现场分体组装而成，安装灵活方便，不受气候条件限制，能满足大规模的工程需要，大大地提高了工作效率，是国家重点推广的新型节能环保建材产品。
The traditional construction method of brick well is to use brick to build the well body, then insert the pipeline into the well body and fill the well pipe joint with cement mortar. The construction efficiency of this process is low, and the connection effect is poor, which will lead to leakage and leakage, which needs to be maintained irregularly. In order to respond to the national policy of energy conservation and emission reduction, in recent years, plastic inspection wells are widely used in a series of projects, such as municipal administration, construction community, old city reconstruction, industrial and mining enterprise construction, etc. the polymer resin is used as the raw material, prefabricated in the factory (the most critical part of the well seat adopts the one-time injection molding process), and is assembled separately on the construction site, which is flexible and convenient to install, and is not limited by climatic conditions System, can meet the needs of large-scale engineering, greatly improve the work efficiency, is a new type of energy-saving and environmental protection building materials products
