INTERMEDIATE CONNECTION PART OF SPACE-PLACED PLASTIC FLUID TRANSPORT PIPE

摘要

PROBLEM TO BE SOLVED: To provide an intermediate connection part of space-placed plastic fluid transport pipes, free of buckling deformation due to the thermal expansion of the plastic fluid transport pipes with a temperature change. SOLUTION: The intermediate connection part 1 of the space-placed plastic fluid transport pipes is constructed by connecting the plastic fluid transport pipes 2 to each other placed in a space such as an underground embedded pipeline or a common duct. In the construction of the intermediate connection part 1, the plastic fluid transport pipes 2 are connected to each other via a flexible/elastic pipe 13 having bending rigidity smaller than the plastic fluid transport pipes 2, flexibility and elasticity in a sagged manner.
