When paving the expansion reinforcing plates, the special expansion reinforcing connecting strip A is firstly placed in the special expansion reinforcing connecting strip assembling groove structure of each of the plates. When continue paving, the special expansion reinforcing connecting strip B is pre-inserted into the special expansion reinforcing connecting strip assembling groove structure of one plate, and the adjacent another plate is effectively spliced with the previous one through its special expansion reinforcing connecting strip assembling groove structure and special expansion reinforcing connecting strip. Finally, both the expansion reinforcing connecting strips A of the adjacent plates contact with the expansion reinforcing connecting strip B to expand and fix with each other, so that the two adjacent plates are effectively connected. The operation time for expansion and fixation after the contact between the expansion reinforcing connecting strip A and the expansion reinforcing connecting strip B is 2 minutes for basic curing, which reaches the final use strength after 12 hours. The tensile strength is 1.6 kN/m.
