The invention discloses a construction process of a tunnel structure with an anti-seepage function, the construction process adopts a first freezing-guniting-steel bar laying-concrete pouring mode for construction, guniting slurry is composed of cement, water, an anti-freezing agent and an accelerator, the guniting slurry is reasonable in component proportion and has the characteristics of rapid hardening, early strength and the like, and the construction process is simple and convenient. Cracking, falling and other phenomena are effectively avoided, the guniting slurry and the pouring concrete are good in adaptability, and the water seepage prevention effect of a tunnel structure is improved. The pouring concrete is reasonable in component proportion, low in slurry viscosity, high in infiltration capacity and good in fluidity, the pouring effect can be improved, and the pouring concrete further has the advantages that the solidification time is short, the size does not shrink during solidification, and the c
