Title:
STEEL MATERIAL FOR UNDERGROUND CONTINUOUS WALL, METHOD FOR PRODUCING STEEL MATERIAL FOR UNDERGROUND CONTINUOUS WALL, UNDERGROUND CONTINUOUS WALL, AND METHOD FOR CONSTRUCTING UNDERGROUND CONTINUOUS WALL
Document Type and Number:
WIPO Patent Application WO/2008/029835
Kind Code:
A1
Abstract:
A steel material (1) for a underground continuous wall in one embodiment is equipped
with a hat type steel sheet pile (2) and an H-steel section (6), wherein the dimension
(L2) of the H-steel section in the length direction is shorter than the dimension
(L1) of the hat type steel sheet pile in the length direction, overall length of
the H-steel section is arranged within the dimension of the hat type steel sheet
pile, and the rear end (20) of the H-steel section is located closer to the forward
end side than the rear end (18) of the hat type steel sheet pile. In a steel material
for an underground continuous wall in another embodiment, position of the rear
end of the hat type steel sheet pile coincides with the position of the rear end
of the H-steel section in the length direction, forward end (21) of the H-steel
section is located closer to the rear end side than the forward end (19) of the hat
type steel sheet pile, and the separation length (B) between the forward end of
the hat type steel sheet pile and the forward end of the H-steel section is within
35% of the overall length of the steel material for the underground continuous
wall in the length direction. In the method for producing the steel material
for an underground continuous wall, the hat type steel sheet pile and the H-steel
section are secured to each other by welding. The underground continuous wall
is constructed using a plurality of steel materials for an underground continuous
wall. The method for constructing the underground continuous wall uses a plurality
of steel materials for an underground continuous wall.
