Abstract
Recently a demand for adopting a noiseless and vibrationless construction method in the field work is growing more and more in Japan.
PW-method (or the pile wall construction method) presented in this paper is an unique noiseless and vibrationless construction technique of continuous retaining wall in the field by using precast prestressed concrete piles having special cross-section.
Since 1967, when this method was first applied to shore protection works at the Neyagawa River by the Bureau of Construction of Osaka Prefecture, it becomes popular year by year.
This paper introduces the outline of “Draft of design code of self-supporting prestressed concrete sheet piles” prepared by the Research Group on “Pre-fabrication of bank-revetment works” in the Society of Materials Science, Japan.
Various advantages of PW-method over the retaining wall construction method with temporary horizontal sufforts as well as further improvements needed for PW-method are also discussed. In addition, a convenient method of determining the embedded length of piles is proposed on the basis of the theoretical and experimental results.
