Construction method of hydraulic solidifying material liquid replacement pile construction for sediment fall prevention device and the hydraulic solidifying material liquid replacement pile

摘要

PROBLEM TO BE SOLVED: To provide a soil fall prevention device for constructing a hydraulic-setting solidifying liquid substitution pile, which prevents soil and/or clods from collapsing into a substitution pile (hydraulic-setting solidifying liquid) immediately after completion of placing the hydraulic-setting solidifying liquid substitution pile and while the hydraulic-setting solidifying liquid has not hardened yet.;SOLUTION: A soil fall prevention device for constructing a hydraulic-setting solidifying liquid substitution pile has a funnel-like shape, of which the upside is an inverted pyramid-shaped part with a relatively blunt angle while the downside is an inverted pyramid-shaped-cylindrical part with a relatively sharp angle. The device is split at least into two sections in the axial direction. The split sections are connected with each other by hinges to be openable and closable, and the opening/closing end sides can be joined to each other to be fixed with fixtures.;COPYRIGHT: (C)2012,JPO&INPIT
