Abstract

PURPOSE:To prevent the overflowing and flooding of river water when the river water is increased by a method in which a steel plate is bent into an L-shape form which enables plural steel plates to be connected, and horizontal walls and vertical walls are connected with detachable supporters. CONSTITUTION:A movable retaining wall is made up of an L-shaped steel plate 1, a horizontal wall 2, a vertical wall 3, a supporter 4, bolts 5', a water-sealing rubber plate 6, a sponge mat 7, and piles 8. A tiered portion of a depth corresponding to thickness is provided on one end of the steel plate 1, and the tiered portion is connected with the other end of the steel plate, the water-sealing rubber plate 6 is attached to the steel plate 1 from the river water side and connected with the bolts 5'. In setting them on the top of the levee, the sponge mat 7 as a water-sealing material is interposed between the horizontal wall 2 and the top to prevent the leakage of water because the top is not necessarily flat. When the horizontal wall 2 is equal in length to the vertical wall, sufficient resistance against water pressure can be obtained by placing them simply on the top, however, they are fixed through the vertical wall 2 by the piles 8 in order to prevent unexpected falling down of the retaining wall.

【発明の詳細な説明】この発明は河川等の増水時に対処するだめの移動擁壁に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movable retaining wall that can be used to cope with rising water levels in rivers and the like.

在しない方が好ましいことは明らかである。Typhoons, heavy rainfall, melting snow, etc. often cause rivers to swell and overflow, and in the past, it was common practice to stack sandbags (dohyo) at the top of embankments to deal with this. Ta. And even though it was unnecessary in normal times, once it was piled up, it was left alone without being removed, which was typical of A-Shi. However, it is clear that it would be better not to exist on the embankment, Ten 91, as it used to be a walking path for the general public and a play area for children, when the water is not rising.

擁壁を提供することをＩＩ的とするものである。Therefore, the present invention has a structure in which a plurality of steel plates bent into an L-shape can be connected, and the horizontal and vertical walls of the steel plates are connected by a removable supporter, which can be installed only when necessary, and can be installed only when necessary. The second object is to provide a movable retaining wall that can be removed if necessary.

L is a steel plate bent into an L-shape so as to have a horizontal wall 2 and a vertical wall 3; The free ends may be bent downwards on the horizontal wall 2 and outwards on the vertical wall 3, respectively, as shown.

を何枚でも連結することが可能となる。A supporter 4 connects the horizontal wall 2 and the vertical wall 3, and the supporter 4 is detachably connected to the horizontal wall 2 and the vertical wall 3 by bolts 5. In addition, a plurality of steel plates 1 whose width is not very wide are connected in series, but in this case, as shown in Fig. 1 of the steel plate 1, one end of the steel plate 1 has a width approximately equal to the thickness of the steel plate 1. A deep stepped portion is provided, the other end is engaged with this stepped portion, and a water stop rubber plate 6 is applied from the river side, and these are connected with bolts 5' so as to be opened. Therefore, steel plate 1
It is possible to connect any number of sheets.

８を打ち込んで固定すればよいのである。A retaining wall is constructed according to the following two steps, and as mentioned above, this retaining wall is usually built at the top of a river embankment.
Although it is possible to simply place this at the top, this top is not necessarily smooth like the steel plate 1, so there is a gap between the bottom surface of the horizontal wall 2 and the top. Water may leak from small gaps. Therefore, in order to prevent this, a closed-cell sponge cloak 7 is interposed between the horizontal wall 2 and the top end as a stopper. Furthermore, according to the results of experiments conducted by Nagisa Fuben, when the lengths of horizontal wall 2 and vertical wall 3 are equal, they can be installed by the above method, that is, they can be simply placed without any special fixing means. It was able to withstand the water pressure. This can be proven through calculations, but when water pressure is applied to the vertical wall 3, it is applied more strongly to the horizontal wall 2, and as a result, it is stable. However, in order to prevent it from falling over accidentally, a stake 8 can be driven into the top of the horizontal wall 2 and fixed.

る。As mentioned above, the movable retaining wall according to the present invention can be moved freely, so it only needs to be installed in so-called emergencies, and during normal times, it can be removed and left in the normal top position. When storing these, the steel plates are bent into an L-shape and the supports are detachable, so they can be stacked one on top of the other as shown in Figure 5, and therefore the space is small. It has the following advantages.
