る。When constructing such a levee body, first, a sheet pile is driven on the seabed ground, then a rubble mound is provided, sand is thrown in, and a block is thrown in the front. There is a problem that the pile sheet piles are extremely unstable against waves during the period from the installation to the installation of a rubble mound and the addition of sand, which makes stable work impossible.
本発明は、前記従来の問題点を解消するためになされた
ものであり、矢板を打設して堤体を構築する際に、波浪

工方法を提供することを解決課題としたものである。The present invention has been made to solve the above-mentioned conventional problems, and when constructing a dam body by driving a sheet pile, it is possible to construct a dam body in a stable state against waves. The problem to be solved is to provide a construction method.

に、安定した状態で堤体の施工ができることになる。As a means for solving the above problems, the method of constructing a dam body of the present invention includes a steel pipe sheet pile whose top is located above the water surface, and a straight sheet pile whose top is located slightly above the bottom of the water. After continuously setting the space between the steel pipe sheet piles on the bottom of the water, place a straight sheet pile with an appropriate height on the straight sheet pile, and place it slightly below the top of the straight sheet piles. It is characterized in that the work of installing levee materials such as rubble mound, sand, and blocks before and after the height is repeated until the levee material is installed up to the top end of the steel pipe sheet pile. Since the waves during construction pass over the straight sheet piles between the steel pipe sheet piles, it is possible to construct the dam body in a stable state without applying large force such as waves to the steel pipe sheet piles.

る。According to the method of constructing a dam body using the steel pipe sheet pile and the straight sheet pile of the present invention described above, (1). When constructing the cut-off wall, by positively providing a space between the steel pipe sheet piles and the steel pipe sheet piles, the waves are not allowed to pass through the space and the steel pipe sheet piles are not collided with all of the waves. The resistance due to waves can be reduced as much as possible.

While reducing the resistance of waves to the steel pipe sheet piles, add straight sheet piles between the steel pipe sheet piles little by little, and at each addition, install the dam material before and after the top of the straight sheet piles to a height slightly below it. Therefore, the force of the waves does not act directly on the straight sheet pile, and the straight sheet pile can be stably installed. Moreover, since the material of the dam body is installed at each foot while adding the straight sheet piles little by little, the dam body can be constructed in a stable state and the efficiency of the construction work can be improved.
