When installed in the tunnel 3, the receiving substrate 4 needs to be fixed at an intermediate position in the bottom of the tunnel 3, this position being set with reference to the position of the analogous T-shaped substrate of the prior art. In order to realize the quick combination of the prefabricated wall body 2 and the bearing substrate 4 and save the installation time, a groove is arranged on the bearing substrate 4 and can be used for accommodating the prefabricated wall body 2; in actual installation, a short side of the prefabricated wall body 2 is inserted into the groove, so that the prefabricated wall body 2 stands on the bearing base.
According to the intermediate wall, the bearing substrate 4 with the groove and the prefabricated wall body 2 are combined to form the wall body, so that the number of times and time for pouring and fixing are greatly reduced, the construction period is shortened, and the cost input is reduced.
