The construction mannered null upper part of the earth and sand falling prevention device and the hydraulic property solidification material liquid displacement post for hydraulic property solidification material liquid displacement

摘要

PROBLEM TO BE SOLVED: To provide a sediment fall preventing apparatus for constructing a hydraulic solidifying material liquid displacement pile, which eliminates the fall of soil lumps and sediment into a hydraulic solidifying material liquid (displacement pile) before the hydraulic solidifying material liquid is solidified after the construction end of the hydraulic solidifying material liquid displacement pile.;SOLUTION: The sediment fall preventing apparatus for constructing the hydraulic solidifying material liquid displacement pile is formed into a funnel shape with an inverted conical part 2 at the upper part and a cylindrical part 3 at the lower part, and bisected in an axial direction. The bisected parts are connected in an openable/closable manner to each other, and the mutual open ends are provided with fixtures 5 for fixing both ends so that the mutual open ends can be adjusted to each other and fixed.;COPYRIGHT: (C)2011,JPO&INPIT
