The invention discloses a continuous synchronous grouting hydraulic control system which comprises a grouting main oil cylinder set arranged in parallel, a first pumping oil cylinder set arranged in parallel and a second pumping oil cylinder set arranged in parallel. Mode reversing valves and reversing valve groups respectively connected with two high-pressure oil sources are arranged on oil paths between the grouting main oil cylinder group and the first pumping oil cylinder group and between the grouting main oil cylinder group and the second pumping oil cylinder group; the reversing valve set comprises a first reversing valve located between the mode reversing valve and the grouting main oil cylinder set, a second reversing valve and a third reversing valve, wherein the second reversing valve and the third reversing valve are located between the mode reversing valve and the first pumping oil cylinder set, and the grouting main oil cylinder set is provided with a proximity switch in a matched mode, wherein
