Title:
PIPE LINE STRUCTURE AND DEFORMED PIPE USED IN THE PIPE LINE STRUCTURE
Document Type and Number:
Japanese Patent JP2002013669
Kind Code:
A
Abstract:
To shorten length L of integrally formed line of a deformed pipe 2 against an nonuniform force P without having to place concrete.
A hard plate 30 is integrally annexed to the deformed pipe 2 and against an nonuniform force P by an earth pressure on the hard plate 30 by earth pressure exerted on the hard plate 30. When the earth pressure exerted on the hard plate 30 is higher than the nonuniform force exerted on the deformed pipe 20, the deformed pipe 20 is not moved by the nonuniform force P and thereby, a need to integrally form line containing the deformed pipe 20 is eliminated. Furthermore, even when it bypasses other buried object D, the length L of the integrally formed line can be shortened and a construction cost can be reduced.
