Limiting side plates 16 are respectively provided on the side walls of the prefabricated middle tube 2. After the prefabricated well is assembled, the limiting side plates 16 are placed on the side walls of the prefabricated well chamber, and then the limiting side plates 16 are pressed against the side walls of the prefabricated well through the two locking rings 17. The side walls of the prefabricated well chamber can be supported by the limiting side plates 16, which is beneficial to improve the strength of the prefabricated well chamber.
