The invention relates to the technical field of urban rail transit concrete pouring engineering, in particular to an urban mass transit ballast bed concrete transfer-free direct pouring construction method. The urban mass transit ballast bed concrete transfer-free direct pouring construction method specifically includes the following steps of concrete loading, backward moving, concrete pouring andvehicle retreating, wherein in the concrete pouring process, when the concrete pouring operation face is arrived, pouring is carried out every two meters, three times of pouring is carried out continuously, and even concrete pouring is ensured. Compared with the prior art, an original construction operation method and process flow are changed, concrete is guided into a concrete pouring tank truckfrom a feeding opening and is directly transported to the concrete pouring operation face for pouring construction, cooperation of operation equipment such as a rail car, a flatbed truck and a tracklaying machine is not neede
