Abstract

PURPOSE: To increase resistance to soil pressure in spite of a lesser amount of a resin used in an underdrainage pipe by providing synthetic resin frame rings at intervals through bridging strings and bonding a synthetic resin string with the periphery of the rings by heating so as to form a water permeable film.
CONSTITUTION: Bridging strings 2 of a synthetic resin are continuously extruded as the warp through an extrusion die, and also large-size frame rings 1 are extruded as the woof intermittently. At the same time as both the bridging strings 2 and the frame rings 1 are molded by extrusion, the surface strings 3 of the pipe wall 5 are continuously extruded as the warp from the periphery of the same die and bonded to the periphery of the frame rings 1. And, they are taken out while being cooled for solidification.
