を特徴とするものである。[Detailed description of the invention] (Purpose of the invention) The purpose of the invention is to provide a caisson that can easily remove earth and sand that adheres to the lower part of the caisson temporarily placed in shallow water. A removable tape is provided on the lower surface of the caisson, and by peeling off this tape, dirt and sand adhering to the lower part of the caisson can be removed together with the tape.

めて難作業で危険の伴うものであつた。(Prior Art) Conventionally, a caisson to be installed on the sea has been cast on land and then temporarily placed in shallow water in the sea as shown in FIG. However, when a temporarily placed caisson is lifted up as shown in Figure 4, a large amount of earth and sand (cohesive soil) of 30 to 40 cm is found attached to the bottom of the caisson, depending on the location and length of time of temporary placement. This soil must be removed when the caisson is installed at its destination, but removing the soil from the bottom of the caisson while it is being lifted by a crane is extremely difficult and dangerous.
本考案はこの土砂の除去を極めて簡単に行ない
得る構造のケーソンを工夫したもので、以下その
一実施例を図面に基き説明する。 The present invention is a devised caisson with a structure that allows the removal of this earth and sand to be carried out extremely easily.One embodiment of the invention will be described below with reference to the drawings.

のである。(Structure of the invention) In the invention, after the caisson is cast on land, a removable adhesive tape is attached to the lower surface of the caisson as shown in Fig. 1. This adhesive tape may be made of any material, and does not need to have particularly high adhesive strength. The point is that the earth and sand that adheres to the tape due to the weight of the caisson when the caisson is temporarily placed in shallow water should peel off together with the tape when the caisson is lifted up.

粘着テープを貼り合せたもので、これは仮置き

に付着した土砂を除去するようにしたものであ
る。 In the embodiment shown in Fig. 2, adhesive tape is attached not only to the lower surface of the caisson, but also to the lower ends of the inner and outer surfaces that extend to the lower surface. It is designed to remove soil and sand that has adhered to the area.
（作用）

中より吊り上げると、土砂に多量の水分を含んで
いるためこの土砂の重みで粘着テープがケーソン
下面から剥れて落下し、土砂はテープと共に除去
される。(Function) When the caisson of the present invention is temporarily placed in shallow water, sediment will adhere to its underside as in the past, but if there is a lot of sediment, lifting the caisson out of the water will absorb a large amount of water into the sediment. Because of the weight of this earth and sand, the adhesive tape peels off from the bottom of the caisson and falls, and the earth and sand are removed together with the tape.
また、土砂の重みで自然に落下しない場合には
テープの一部を引つ張ればテープは土砂と共に容
易に落下する。 Further, if the tape does not fall down naturally due to the weight of the earth and sand, the tape can easily fall down along with the earth and sand by pulling a part of the tape.
（考案の効果）
本考案は上記の如く、ケーソン下面に付着した
大量の土砂がクレーンにて吊り上げた際一気に落
下するので、ケーソンの下面は付着物のない状態
で目的場所へ安定的に本設置することができるも
のである。(Effects of the invention) As mentioned above, with this invention, a large amount of earth and sand attached to the bottom of the caisson falls all at once when it is lifted by a crane, so the bottom of the caisson can be stably installed at the target location without any deposits. It is something that can be done.
