对于管道和检查井的连接方式，我们能够用柔性接口和刚性接口。而检查井的组合件由以下组成：井室、底座、底板、收缩口、支管接入段和井盖。其中，底板主要是用来进行固定、承托检查井的功能；底座则是连接排水主管，也是选用检查井型号的主要根据，是预制检查井的根本；支管接入段接收支线管段接入；井室用来调节支管接入高度，用其来满足部分需接受支管检查井的需要；收缩口和井盖则可以调节检查井与安装地段路面高差，做好安装地路面与检查井的平衡；检查井各部分经现场安装调试，能够迅速拼成适用简单的功能体。
For the connection of pipeline and inspection well, we can use flexible interface and rigid interface. The assembly of the inspection well consists of the following components: well chamber, base, bottom plate, shrinkage opening, branch access section and well cover. Among them, the floor is mainly used to fix and support the function of inspection wells; the base is used to connect the drainage supervisor, and is also the main basis for selecting the type of inspection wells, which is the basis of prefabricated inspection wells; the branch access section receives branch pipe access; the well chamber is used to adjust the height of branch pipe access to meet part of the need to accept branch pipe. The need of inspection wells; shrinkage wells and covers can adjust the height difference between the inspection wells and the pavement in the installation section, and make a good balance between the installation of the pavement and the inspection wells; each part of the inspection wells can be quickly assembled into a simple functional body after on-site installation and debugging.
