<p>PURPOSE:For preventing a bent pipe for example from transferring due to thrust load, to fasten said bent pipe on the base plate of the L-sectional support member fastened on the piles driven under said bent pipe. CONSTITUTION:A proper quantity of piles 2 are driven in the bottom section of a groove previously made for laying a duct, the L-sectional support member 4 made of a base plate 4B for receiveing from downward the side plate 4A applied on the outer side face of the bent pipe 3A of a duct 3 and said bent pipe 3A is fastened on said piles 2, and said bent pipe 3A is placed on said base plate 4B of said support member 4 so as to be applied on said side plate 4A. Thereby, said side plate 4A fastened on said piles 2 and said base plate 4B cooperate with each other to receive effectively the thrust load having occurred at the bent or branch portiona of said duct 3. Thus, said bent portion for example can be prevented from transferring due to thrust load.</p> |
