[0017] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0018] In the prior art, prefabricated ditches need to use other connecting components for end-to-end connection, which makes assembly inconvenient.
