おいては、遮水性を要求されることが多く、隣り合って
設置されたケーソン間の目地の埋立側に、目地材を固定
の上、裏込め石を設けていた。Conventionally, in revetment when industrial waste is used as landfill material, as shown in FIG. 2, after the caisson 2 is sunk on the foundation stone 1 installed on the seabed and the filling sand 3 is filled, By providing backfill stones 4 on the landfill side, it is possible to withstand the earth pressure of the landfill sand 5, and especially in the waste revetment, water impermeability is often required and they are installed side by side. On the landfill side of the joint between the caisson, the joint material was fixed and the backfill stone was installed.
しかしながら、近年大量に出る廃棄物の処分地が不足し
て、土砂等の廃棄物の受入容量を少しでも増加させる必
要性が生じ、上記のごとき裏込め石を設けずに直に廃棄
物をケーソン護岸背面に投入することが検討されてい
る。However, due to the shortage of waste disposal sites in recent years, it becomes necessary to increase the capacity for receiving waste such as earth and sand. It is being considered to put it on the back of the seawall.
ところが、ケーソン間の目地に、従来のように目地材な
どの止水板を設けただけでは、投入する土砂等の廃棄物

なるという問題がある。However, just by providing a water stop plate such as a joint material in the joint between the caisson as in the conventional case, the water stop plate will come off due to the earth pressure of the waste such as earth and sand to be put in, and the water cannot be blocked. There is a problem.
本考案は、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、裏込め石を設けない場合でも、埋立される
廃棄物などの土圧に耐え、かつ隣合うケーソン同志の位
置の変動があっても遮水性を保持できるケーソン目地の
遮水構造を提供することを解決課題としたものである。The present invention was made in order to solve the above-mentioned conventional problems. Even if a backfill stone is not provided, the present invention can withstand the earth pressure of wastes to be landfilled and the position of adjacent caissons can be changed. The problem to be solved is to provide a water-impervious structure with caisson joints that can maintain the water-impermeable property.

より対応している。As a means for solving the above problems, the water-impervious structure for caisson joints of the present invention fixes the joint material on the landfill side of the joint between the caisson installed adjacent to each other, and covers the outside of the joint material. , And the other end of a steel plate having a convex cross section whose one end is fixed to one caisson, and the other end of a steel plate having one end that variably wraps with each other to the other caisson. While the pressure is applied to the steel plate having the convex cross section, the positional fluctuations between the adjacent caissons correspond to each other by the movement of the lap portion between the end portion of the above steel sheet and the end portion of the other steel sheet.
以下図面を参照して本考案の実施例を説明するが、第１
図は本考案の一実施例におけるケーソン目地の遮水構造
を示す斜視図である。An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a water blocking structure of a caisson joint according to an embodiment of the present invention.
まず、第１図に示すごとく、隣り合って設置された護岸

より矢印Ｓで示す海側に、波圧抵抗用目地材13を配置し
ている。First, as shown in FIG. 1, a joint material 11 is fixed to the caisson 10 with tacks 12 or the like on the landfill side indicated by an arrow G in the figure of the joint 10A between the seawall caissons 10 which are installed adjacent to each other. And, if necessary, joint material 11 of joint 10A between each caisson 10
The joint material 13 for wave pressure resistance is arranged on the sea side indicated by the arrow S.
