摘要

Problem to be solved: to provide a joint member of a precast concrete wall buried pipe capable of connecting the buried pipes easily using a core even if an adjacent precast concrete wall is connected by dropping.First and second precast concrete walls 24 'buried pipeThe open end 12 for connection 4 'The core 6 connecting 22 is press fitted into the first buried pipe connection portion 10 into which the compressed Coyle spring 7 is insertedInsertion preventing member 30 is inserted into hole 14In a state where the core 6 is prevented from being engaged by engaging withA pair of precast concrete walls2 'Remove member 30The tension member 31 is pulled and inserted into the hole 14.15 out ofThe first connection opening end 12 and the second connection opening 22 are connected by the core 6 biased by the compression spring 7.First and second precast concrete wallsA mortar is filled between the joint between 2 'and the outer surface of core 6.Diagram
