〈産業上の利用分野〉
この考案は鋼矢板、特に打ち込みを円滑にする
鋼矢板の構造に関する。[Detailed Description of the Invention] <Industrial Application Field> This invention relates to steel sheet piles, particularly the structure of steel sheet piles that facilitates driving.

手を圧入して連結していく。<Conventional technology> Normally, steel sheet piles are made of steel sheet piles, as shown in Figures 2 and 3.
It is known that the earth retaining web 1 and the flange supporting it are formed into a substantially U-shape, and each flange edge has a curved joint. Then, the U-shapes are arranged alternately, and the joints of the adjacent steel sheet piles are press-fitted into the joints of the steel sheet piles using a machine such as a piler to connect them.

う問題を生じた。<Problem to be solved by the invention> However, in order to perform the above connection, not only earth and sand but also crushed stones are packed into the curved part of the joint that has already been driven, which makes it difficult to press-fit the next steel sheet pile to be driven. Otherwise, the steel sheet piles were damaged.

となる。<Means for solving the problem> This invention was made based on the above-mentioned purpose, and its gist is that in a steel sheet pile consisting of a web and subsequent left and right flanges having joints on both edges, The joints are each filled with a compressible plugging material and are made of steel sheet piles with blinds provided at the driving tips. Here, the compressible plugging material filled in the joint part prevents earth and sand from entering from around the joint part when driving the steel sheet piles, and after driving, it facilitates press-fitting of the joint part of adjacent steel sheet piles. After construction, the watertightness of the joints is maintained. In addition, if the blind spot is sharpened at the driving part at the tip of the joint, it will be easier to press-fit the steel sheet pile.

Compressible plugging material prevents dirt from entering the joint from the surrounding area. The next steel sheet pile is inserted into the joint of the first steel sheet pile that does not contain earth and sand while compressing the compressible plugging material, and after fitting, the compressible plugging material is used to maintain watertightness between each steel sheet pile. make it good

and 3 are left and right flanges that are continuous with the web and have a generally U-shaped cross section as a whole. Further, reference numeral 4 denotes a joint portion in which each end edge of the flanges 2 and 3 is wound outward, and these joint portions are connected alternately as shown in Fig. 3. In addition, 5 is a rope hanging hole for hanging the steel sheet pile with a crane or the like.

盲が溶接している。 Therefore, in this invention, the convex portion of the joint portion 4 is filled with a compressible plugging material 6 such as urethane foam resin or styrene foam resin over the entire longitudinal direction. Here, if the ratio of the maximum area of the adjacent steel sheet pile before driving to the minimum area after driving is more than 200:1, the compressible plugging material 6 will not be watertight, and if it is less than 50:1, it will be difficult to press fit. However, this does not necessarily mean that the invention cannot be completed, and therefore this invention is not limited to the above numbers. A sharp piece-shaped blind is welded to the lowermost joint portion of the compressible plug 6.

Steel sheet piles can be press-fitted smoothly without dirt, stones, etc. entering the joint. In addition, when driving the next steel sheet pile, stones etc. do not enter the joint of the first steel sheet pile, so press-fitting is easy.
Even after press-fitting, the watertightness of the joint can be improved by compressing the compressible plugging material.
