(57) To provide a joint member for a precast concrete wall buried pipe which makes it possible to easily connect the buried pipes using a core even if adjacent precast concrete walls are connected by dropping.solution: A core 6 connecting connection opening ends 12, 22‘ for buried pipes 4, 4‘ of first and second precast concrete walls 2, 2‘ is press-fitted into a first buried pipe connecting part 10 into which a compression coil spring 7 is inserted; with a pull-out prevention member 30 engaged with insertion holes 14 and 15 to prevent the core 6 from coming off, a pair of precast concrete walls 2, 2‘ are lined up by dropping; the pull-out prevention member 30 is pulled out from the insertion holes 14 and 15 by pulling a tension member 31; the core 6 urged by the compression coil spring 7 connects the first connection opening end 12 and the second connection opening end 22; and thereby mortar fills between a joint between the first and second precast concrete walls 2, 2‘ and the outer peripheral surface of the core 6.
