Problems solved by technology

In the case of filling mortar in this way, there is a disadvantage that after the steel pipe sheet pile is driven into the ground, it is necessary to discharge the soil and sand inside the joint with a water jet or the like and fill the joint with mortar. , therefore, on-site work takes effort and time
However, since the cross-sectional shape of the combined steel sheet pile has a wide range, it is necessary to find a way

Embodiment Construction

[0090] Below, while referring to the attached Figure 1 Embodiments of the present invention will be described.

[0091] Such as figure 1 and figure 2 As shown, the steel wall 3 of this embodiment is comprised by combining the hat-shaped steel sheet pile 1 which is a steel sheet pile, and the steel pipe 2. As shown in FIG. The steel pipe 2 is in contact with the hat-shaped steel sheet pile 1 so that the longitudinal direction of the steel pipe 2 follows the longitudinal direction of the hat-shaped steel sheet pile 1 . Here, the respective longitudinal directions of the hat-shaped steel sheet pile 1 and the steel pipe 2 are parallel to each other, and these longitudinal directions are vertical directions.

[0092] 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 each other, and extending from the top ends of the left and right flanges 1b parallel to the web 1a. A pair of arms 1...

Abstract

Disclosed is a steel wall provided with both excellent rigidity and excellent waterproofing properties. Also disclosed is a construction method for a steel wall, whereby a construction method that suppresses vibration and noise, which was difficult with conventional composite sheet steel pile, can be readily used. Said steel wall (3) is formed by a combination of hat-shaped sheet steel piles (1) as sheet steel pile and steel pipes (2). In this steel wall (3), a plurality of hat-shaped sheet steel piles (1) are connected by joints (1d) to provide a sheet steel pile wall, and steel pipes (2) touch all or part of the hat-shaped sheet steel piles (1) in this sheet steel pile wall, with the longitudinal direction of the pipes following the longitudinal direction of the hat-shaped sheet steel piles (1).

Description

technical field [0001] The present invention relates to a steel wall and a steel wall construction method used in retaining works, cofferdams, revetments, fillings, embankments, and the like. Background technique [0002] In the past, steel sheet piles and steel pipe sheet piles have been used in various projects such as earth retaining works, cofferdams, revetments, fillings, and embankments. Steel sheet piles and steel pipe sheet piles are used differently depending on the required rigidity. Generally, the steel sheet pile is used in the case where the rigidity can be low, and the steel pipe sheet pile is used in the case where the rigidity is required. [0003] Here, the steel pipe sheet pile has a larger joint margin than the steel sheet pile. Therefore, when water-tightness is required in the construction of cofferdams, bank revetments, etc., a method of filling the joint space with cement mortar in bags is generally used. When this method is used in waterside enviro...
