The invention relates to a bridge construction technology, and relates to the technical field of bridge construction, the bridge construction technology comprises the steps of bridge abutment construction, bridge pier concrete pouring construction, precast beam pavement, precast beam connection and pavement laying, and a precast beam production technology comprises the steps of A, precast formwork installation to form a pouring cavity, B, concrete pouring into the pouring cavity after reinforcing steel bars are bound, C, retarder smearing, D, concrete pouring and E, concrete pouring. And D, flushing the retarder, and flushing the retarder through a flushing machine to form a galling surface. According to the method, the retarder is smeared in the production process of the precast beam, so that the concrete shows different solidification degrees, then the retarder and the concrete are flushed and dropped through water with certain pressure, and therefore the plane of the precast beam is in an uneven state, gal
