The poured concrete is then cured to increase the supporting strength of the lining. Therefore, it is necessary to pull additional maintenance trolleys or maintenance tools into the tunnel to cure the concrete. Once the scheduling time is long, it is easy to affect the construction progress. Therefore, the present application provides a new technical solution. Utility Model Content
