The invention discloses a construction method of a soft soil foundation bridge deck slab integral type steel-concrete pedestal, which is applied to pedestal soft foundation construction, soft soil such as sludge occurring in other temporary engineering construction is solidified, the bearing capacity of the solidified foundation is high, spoil is reduced, the sludge soil is turned into wealth from waste, and pollution to the environment is reduced. The overall rigidity of the constructed pedestal is high, deformation caused by possible differential settlement of a foundation is avoided, and the flatness requirement of the bottom of a bridge deck slab is met; only a small amount of profile steel is used as a positioning framework, the main structure installation work amount is small, a plurality of pedestals can be formed through one-time pouring after steel bars and formworks are installed, and the pedestal construction period is short; the bottom plate is convenient to model, only a small amount of profile s
