本発明は主として本ならし用の捨石投入に使用されうる
捨石投入方法及び装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method and apparatus for introducing rubble which can be mainly used for adding rubble for book leveling.
従来、海上にケーソン式の防波堤等の構築物を設置する
場合には、海底に捨石マウンドを設け、その上にケーソ

形成する。Traditionally, when constructing a structure such as a caisson-type breakwater on the sea, a rubble mound is placed on the seabed and a caisson is installed on top of it. A rubble mound is formed by leveling the mound by adding thinner rubble on top of the mound.
そこで従来、その捨石マウンドを形成する際には、クレ

後所定の捨石投入位置にケーシングを移動して捨石投入
を行っている。Conventionally, when forming the rubble mound, the rubble is introduced by opening the rubble input port at the bottom of the casing suspended at a predetermined position underwater using a crane ship, etc., and then the casing is placed at the predetermined rubble input position. They are moving and putting in rubble.
しかしながら、凹凸のはげしい海底に一定高さの捨石マ

し作業をする必要があった。However, in order to form a rubble mound of a certain height on an extremely uneven seabed, it is necessary to open and close the rubble input port of the casing arbitrarily. It was difficult to close the input port, and as a result, it was very difficult to maintain the height of the rubble mound at a constant top position, and it was necessary to level the mound again after the rubble was removed.
そこで、本発明は前記従来の問題点を解消し、ケーシン

を目的としたものである。SUMMARY OF THE INVENTION Therefore, the present invention solves the above-mentioned conventional problems and allows the rubble inlet at the lower end of the casing to be opened and closed arbitrarily and easily using the arch action of the rubble. The object of the present invention is to provide a method and device for introducing rubble that can form a rubble mound that does not require leveling work.

成される。That is, the method of introducing rubble according to the present invention involves adjusting the opening of the rubble input port at the lower end of the casing for inputting rubble to be close to the limit at which the arch action occurs, and then inserting the rubble.
When the required rubble is completed, the above-mentioned opening degree is reduced to the opening degree at which an arch action occurs, and the casing is moved to the next rubble-dropping position, and then the rubble-stone is loaded by repeating the above operation. The rubble feeding device has a rubble feeding opening at the lower end of a rubble feeding casing that can be moved to a required position, and the opening of the rubble feeding opening is set to a point just before the limit at which arch action occurs. A semi-fixed partition plate that can be adjusted is provided, and a movable partition plate is provided below the semi-fixed partition plate that can reduce the opening of the rubble input port to an opening that causes arch action. .

図である。Embodiments of the rubble feeding method and the rubble feeding device of the present invention will be described below with reference to the drawings. FIG. 1 is an overall side view of the rubble feeding device in one embodiment of the present invention, and FIG. FIG. 2 is an enlarged side sectional view of a main part of the rubble input port of the casing shown in FIG. 1;
まず、第1図に示すごとく、クレーン船1で捨石投入用

て捨石用の砕石8を投入するが、このケーシング2内に
砕石8が充満されたところでクレーン船1で吊り、海中
の所定の位置にセットするようになっている。First, as shown in Fig. 1, a casing 2 for throwing in rubble is lifted up by a crane ship 1, its upper end is exposed above the sea surface, and crushed stones 8 for rubble are thrown into the casing 2 using a grab boat (not shown). However, once the casing 2 is filled with crushed stones 8, it is lifted by a crane ship 1 and set at a predetermined position in the sea.
次に、第2図に示すごとく、このケーシング2の下編部

よって操作される可動仕切板6を設けている。Next, as shown in FIG. 2, the opening of the rubble stone inlet 9 in the lower part of the casing 2 can be adjusted to just before the limit at which the arch action of the crushed stones 8 occurs. Semi-fixed partition plate 4 operated by cylinder 5
are provided tilting from side to side, and at the bottom of this semi-fixed partition plate 4 is a cylinder 7 that can be operated by a cylinder 7 that can reduce the opening of the rubble input port 9 to the opening that causes the arch action of the crushed stones 8. A movable partition plate 6 is provided.
そこで、上記半固定仕切板4は砕石8の大きさによって
、そのアーチアクションの現象が発生する限度の直前付
近にシリンダー5を動かしてあらかじめセットしておき

然落下させる。Therefore, depending on the size of the crushed stone 8, the semi-fixed partition plate 4 is set in advance by moving the cylinder 5 to a position just before the limit at which the arch action phenomenon occurs, and in this state, the uneven seabed ground G Crushed stone 8 is allowed to fall naturally on top.
落下した砕石8が山積状になり、捨石投入口9まで盛上

かに閉じる方向に操作することにより、捨石投入口9で
砕石8にアーチアクションを発生させる。The fallen crushed stones 8 form a pile, swell up to the rubble input port 9, connect with the crushed stones 8 in the casing 2, and when the crushed stones 8 stop falling naturally, the cylinder 7 of the movable partition plate 6 is operated in the direction of slightly closing it. By doing so, an arch action is generated in the crushed stone 8 at the rubble input port 9.
その結果、その状態でケーシング2をクレーン船1で吊
り上げても砕石8が捨石投入口9がら自然落下すること
がない。As a result, even if the casing 2 is lifted by the crane ship 1 in this state, the crushed stones 8 will not naturally fall from the rubble input port 9.
以上のごとく所定の捨石終了時に、ケーシング2を次の
捨石投入位置に移動させ、ケーシング2の下端に設けで
ある定規板3を出来上がった砕石山の天端Tに当てがい
、セントし、そこで可動仕切板6を開くことにより再び
砕石8の投入を行い、以下上記の操作を繰返すことによ

ドが形成される。As mentioned above, when the prescribed rubble is finished, the casing 2 is moved to the next rubble input position, and the ruler plate 3 provided at the lower end of the casing 2 is applied to the top T of the completed crushed stone pile, and it is moved there. By opening the partition plate 6, the crushed stones 8 are loaded again, and by repeating the above operations, the rubble loading operation is continued and a continuous rubble mound is formed.
その結果、海底不整地盤Gの不整に関係な(、天端Tの

必要としない。As a result, it is possible to place the crushed stones 8 while keeping the height of the top T constant (related to the irregularity of the uneven seabed ground G), but during this time, the natural fall of the crushed stones 8 is controlled by the phenomenon of arch action. By using this, the opening degree of the rubble input port 9 can be adjusted by simply opening and closing the cylinder 7 of the movable partition plate 6, and the semi-fixed partition plate 4 is first adjusted to the opening degree suitable for the crushed stone 8. Just make the adjustment and no further operation is required.
従って、本発明の捨石投入方法を採用した装置ではケー

ので、捨石投入作業の能率を向上することができる。Therefore, in a device adopting the rubble stone feeding method of the present invention, by slightly closing the movable partition plate of the rubble stone feeding port of the casing, the arch action of the crushed stone is used to prevent the falling of the rubble and the casing is moved to the desired position. The efficiency of the rubble loading work can be improved.

済的である。Further, since the operation of closing the rubble input port of the casing is easily performed, a rubble mound of uniform height can be created, and there is no need for leveling work of the rubble after inputting the rubble, which is very economical.
