An assembling structure for connecting spiral-wave type pipe is provided to securely and completely prevent leak of water for a long term by reinforcing ductility of rubber sheet which is not vulcanized and thus blocking to be pushed out. An assembling structure for connecting spiral-wave type pipe comprises a spirally formed projection(1a) and recess(1b) on its surface and both recesses of a connection part connecting spiral wavy pipes(1) of plastic resin each other. At least two rows compressive projection(5a) mating to recess of a spiral wavy pipe is connected to face a pair of semicircular type connection part(5) and seals against water with compression of rubber sheet which is not vulcanized and a packing for blocking water. The ductility of the rubber sheet is reinforced by adhering a mesh(4) consisting of a seal(4a) to one surface of the rubber sheet which is not vulcanized.
