Conservation structure and application manner null of the apecials embedding in the stratum which it is easy to convert liquefied

摘要

PURPOSE: To perform efficient protection of a profile pipe being an embedded line which is apt to be damaged owing to liquefaction occurring when an earthquake occurs. ;CONSTITUTION: When a profile pipe 1 is embedded in a stratum apt to be liquefied, support piles 3 are driven in the periphery of the embedding part and a net-form surrounding material 2 which is locked to the support piles 3 to surround an embedding area is laid. Gravels 7 are disposed inside the net-form surrounding material 2 to form a gravel layer and the profile pipe 1 is embedded in the gravel layer together with embedding earth.;COPYRIGHT: (C)1993,JPO&Japio
