【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、鋼管矢板と直線矢板とを交互に組合せること
により堤内外の海水を交換できる鋼管矢板と直線矢板を
用いた防波堤に関するものである。TECHNICAL FIELD The present invention relates to a breakwater using a steel pipe sheet pile and a straight sheet pile capable of exchanging seawater inside and outside the bank by alternately combining steel pipe sheet piles and straight sheet piles. is there.
従来、鋼管矢板を連続して設置することにより、防波堤
を構築することが行なわれている。Conventionally, a breakwater has been constructed by continuously installing steel pipe sheet piles.
また、近年、堤内と堤外の海水を交換できる構造の防波
堤が求められているが、鋼管矢板を用いた防波堤で、堤
内と堤外の海水の交換を行なうとすれば、鋼管矢板を間
隔をあけて設置することになるが、このままでは海底地
盤が海水の流れによって洗掘され、根入れ長が短かくな
り、強度が不足するという問題が予想される。In recent years, a breakwater with a structure that can exchange seawater inside and outside the breakwater has been required. Although it will be installed, it is expected that there will be problems that the seabed will be scoured by the flow of seawater, the rooting length will be short, and the strength will be insufficient.
本発明は、前記従来の問題点を解決するためになされた
ものであり、鋼管矢板と直線矢板を交互に用いて、海水
交換ができ、かつ海底地盤の洗掘を防止できる防波堤を
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 conventional problems, and provides a breakwater capable of exchanging seawater and preventing scour of the seabed by alternately using steel pipe sheet piles and straight sheet piles. Is the problem to be solved.
上記の課題を解決するための手段として、本発明の防波
堤は、それぞれ所定の間隔をあけて海底地盤内から水面
上まで設置した複数の鋼管矢板の間に、その鋼管矢板の
下端部から海底地盤面と同じか、またはやや上方まで直

おり、鋼管矢板の海底地盤への根入れ部が直線矢板で遮
水されて洗掘が防止されると共に、堤内外の海水は直線
矢板の上部から自由に交換されることになる。As a means for solving the above-mentioned problems, the breakwater of the present invention has a plurality of steel pipe sheet piles installed from the inside of the seabed ground to above the water surface at predetermined intervals, respectively, from the lower end of the steel pipe sheet pile to the seabed ground. It is composed of a straight sheet pile, which is the same as the surface or a little higher than the surface, with a joint, etc., and the straight sheet pile blocks the root of the steel pipe sheet pile to the seabed ground to prevent scouring. At the same time, seawater inside and outside the bank will be freely exchanged from the top of the straight sheet pile.
以下図面を参照して本発明の実施例を説明するが、第１

２図は第１図の平面図である。An embodiment of the present invention will be described below with reference to the drawings.
1 is a front view of the installation of a breakwater in one embodiment of the present invention, and FIG. 2 is a plan view of FIG.
まず、この防波堤を設置するに当っては、第１図に示す

はやや上方になるように打込みなどにより介設する。First, in installing this breakwater, as shown in FIG. 1, a plurality of steel pipe sheet piles 1 are driven into the seabed B at predetermined intervals so that the head of the breakwater W. After being installed so as to project from L, the lower ends of the straight sheet piles 2 between the respective steel pipe sheet piles 1 substantially match the lower end portions of the steel pipe sheet piles 1, and the upper end portions thereof are the same as the surface of the seabed ground B. Or, insert it so that it is slightly above.
ここで、これらの鋼管矢板１と直線矢板２との継合部の
継手３としては、従来使用されている鋼管矢板用継手、
例えば第２図に示すごとくＬ形及びＴ形の継手３等を用
いるものとする。Here, as the joint 3 at the joint between the steel pipe sheet pile 1 and the straight line sheet pile 2, a conventionally used steel pipe sheet pile joint,
For example, as shown in FIG. 2, L-shaped and T-shaped joints 3 and the like are used.
本発明は、それぞれ所定の間隔をあけて、海底地盤内か

矢板の下端部から海底地盤面と同じか、またはやや上方
まで直線矢板を介設したから、 (1)．直線矢板を鋼管矢板の根入れ部に設置するので、
海底地盤における根入れ部が遮水され、根入れ部の洗掘
が防止され、強固な防波堤が得られる。The present invention, at a predetermined interval, respectively, between a plurality of steel pipe sheet piles installed from the inside of the seabed to the surface of the water, a straight sheet pile from the lower end of the steel pipe sheet pile to the seabed ground surface or slightly above. Since it was installed, (1). Since a straight sheet pile is installed at the root of the steel pipe sheet pile,
The root-entry part in the seabed is shielded from water, scour of the root-entry part is prevented, and a strong breakwater is obtained.
(2)．鋼管矢板の海底地盤から上の部分は隙間があるの
で、堤内の海水と堤外の海水を自由に交換できる。(2). Since there is a gap above the seabed ground of the steel pipe sheet pile, the seawater inside the bank and the seawater outside the bank can be freely exchanged.
という効果を奏することができる。It is possible to achieve the effect.
