Title:
STEEL WALL AND METHOD FOR CONSTRUCTING STEEL WALL
Document Type and Number:
WIPO Patent Application WO/2011/142047
Kind Code:
A1
Abstract:
Disclosed is a steel wall which combines high rigidity equivalent to that of a steel pipe sheet pile wall and high water cut-off properties equivalent to those of a steel sheet pile wall. Also disclosed is a method for constructing the steel wall, to which a technique for suppressing vibration or noise, which was difficult to do with a conventionally combined steel sheet pile can be easily applied.
Specifically disclosed is a steel wall (3), wherein a plurality of hat-shaped steel sheet piles (1) are connected by joints (1d) so as to have a steel sheet pile wall, and steel pipes (2) come into contact with all of the steel sheet pile wall, or some of the hat-shaped steel sheet piles (1) so as to make the longitudinal direction thereof follow the longitudinal direction of the hat-shaped steel sheet piles (1). The construction of the steel wall (3), wherein the steel pipes (2) and the hat-shaped steel sheet piles (1) with which the steel pipes (2) come into contact are joined in contact parts with one another over the entire length of the contact parts, or the combined steel sheet pile is provided by joining the steel pipes (2) and the hat-shaped steel sheet piles (1) in some of the contact parts. Then, auger screws of earth augers are inserted into the steel pipes (2), and the combined steel sheet pile is cast by press-in while excavating a wider range of ground than the diameter of the steel pipes (2) under the steel pipes (2).
