Abstract

1. A line pipe of synthetic material, especially sewer pipe of large size diameter, comprising a smooth inner pipe (11, 20) provided with a socket-like enlargement (21, 22) at one end for the reception of the smooth end of another inner pipe, and a separately manufactured outer pipe (2b, 23) provided with corrugations which is pushed into the inner pipe, with the wave crests (10, 24) lying in close contact against the outer surface of the inner pipe and in a given case fastened thereat at intervals, and with the one end of the outer pipe terminating at the rearward shoulder of the enlargement of the inner pipe, characterized in that the inner pipe (11, 20) has a bore of 20 to 50 cm and more and a wall gauge from 3 to 10 mm, the outer pipe (2b, 23) has a wall gauge from 1.5 to 5 mm, the wave crests of the outer pipe are provided with apertures (17) adapted to be closed for a weighting filling material (16) between outer and inner pipes, the outer pipe (2b, 23) terminates at the other end thereof at a distance from the other end of the inner pipe (11, 20), and in that a split sleeve (30) provided with at least two waves (31, 32) which is spaced from the socket-like enlargement (21, 22) through a radial distance is adapted to be brought into form-closed engagement with the terminal corrugation of two adjacent outer pipes (2b, 23).
