description The utility model discloses a shield tunneling machine propelling system hydraulic integrated valve group for tunneling synchronous assembly, which is externally connected with a shield tunneling machine propelling oil cylinder, and the shield tunneling machine propelling oil cylinder internally comprises an oil cylinder rodless cavity and an oil cylinder rod cavity; the hydraulic integrated valve group of the shield tunneling machine propelling system comprises an oil inlet unit, a middle unit and a tail unit. The plurality of middle couplings and the oil inlet couplings are connected in series and spliced in any sequence; the number of the tail couplings is two, and the tail couplings are connected with the two middle couplings located on the outermost side respectively. According to the shield tunneling machine propelling system hydraulic integrated valve group for tunneling synchronous assembly, the technical problems that tunneling synchronous assembly is achieved, valve blocks are too large and too many
