Abstract
This utility model discloses a precast reinforced concrete inspection well, belonging to the technical field of inspection wells. It includes an inspection well and a cover, with a limiting component installed between them. A circular groove four is formed on the top outer side of the inspection well, and two circular grooves, one and three, are formed on the top inner side of the inspection well. Circular groove one and three are connected, and circular groove one is connected to circular groove four. When the water flow is large, inserting a polygonal block into the polygonal groove and rotating it causes a circular rod to drive a gear two, which in turn drives a gear one. Simultaneously, gear one moves the cover upwards via a threaded rod, increasing the inlet area of the inspection well and improving drainage. The rectangular block and groove facilitate the installation and removal of a filter screen, which can filter out larger debris, preventing it from entering the inspection well.
