Embodiment Construction

[0061] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0062] Such as Figure 1 to Figure 3 As shown, the steel wall 3 according to the first embodiment of the present invention is configured by combining the hat-shaped steel sheet pile 1 and the steel pipe (reinforcement material) 2 which are steel sheet piles. A plurality of steel pipes 2 are arranged in parallel at intervals along the longitudinal direction of a wall (sheet pile wall) 4 formed by connecting a plurality of hat-shaped steel sheet piles 1 .

[0063] The hat-shaped steel sheet pile 1 includes: a web 1a; a pair of flanges 1b extending obliquely from both side edges of the web 1a so as to expand from each other; a pair of arms 1c extending from the top ends of the left and right flanges 1b. Extending left and right parallel to the web 1a; and a joint 1d provided at the top end of the arm 1c.

[0064] In addition, the hat-shaped steel sheet pile 1 and the ste...

Abstract

Provided is a steel wall for which construction is simple and for which a wall body, made by coupling steel sheet piles capable of readily having high water resistance, is reinforced with steel pipes or steel H-beams. A wall body (4) is provided by coupling a plurality of hat-shaped steel sheet piles (1) by way of joints. Steel pipes (2) for reinforcing the wall body (4) are provided lined up along the lengthwise direction of the wall body (4). Gaps are provided between the wall body (4) and the steel pipes (2). The wall body (4) is formed as a steel sheet piling wall in a corrugated shape that repeats concavity and convexity in the lengthwise direction. The steel pipes (2) are disposed so as to fit partially into the concave portions of the wall body (4). The top of the wall body (4) and steel pipes (2) are coupled. The coupling of the wall body (4) and steel pipes (2) is by way of concrete. Load transfer occurs between the wall body (4) and steel pipes (2). Thus, a steel wall (3) can be structured to receive and distribute the acting earth load or water load to the wall body (4) and steel pipes (2).

Description

technical field [0001] The invention relates to a steel wall used for water and soil conservation, cofferdam, revetment, filling, embankment and the like. Background technique [0002] Conventionally, steel sheet piles and steel pipe sheet piles have been used for various constructions such as soil and water conservation, cofferdams, bank revetments, landfills, and embankments. Steel sheet piles and steel pipe sheet piles are used according to the required rigidity. Generally, steel sheet piles are used when low rigidity is acceptable, and steel pipe sheet piles are used when high rigidity is required. [0003] Here, the margin of the joint of the steel pipe sheet pile is larger than the margin of the joint of the steel sheet pile. Therefore, when water-tightness is required when constructing cofferdams, bank revetments, etc., a method of filling the joint space with bagged cement mortar is generally employed. When this method is used in waterside environments such as riv...
