DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a weight-compression type finishing method of an underwater rubble mound, which is a basic embankment body of an offshore structure such as a breakwater.

〔従来の技術〕[Conventional technology]

従来、重錘で押圧することによって水中捨石マウンド

Conventionally, in order to finish the crown of an underwater rubble mound by pressing it with a weight, to the height of the design plan, the height of the entire mound of the mound must temporarily exceed the design plan height. After that, the excess is pressed by a weight.

〔発明が解決しようとする課題〕[Problems to be solved by the invention]

ことが必要である。
Generally, the porosity of an underwater rubble mound prior to compaction is about 40%, depending on the particle size of the rubble, and it is about 10 to 15% compacted by pressing with a weight. . Thereafter, even if the pressing operation is repeated, only the pressed peripheral portion is raised, and the desired finished surface cannot be obtained. That is, since there is a limit to the pressing by the weight, it is necessary that the amount of the extra rubble exceeding the design plan height is an appropriate amount without excess or deficiency determined in relation to the above-mentioned density.

However, in practice, the rubble dumping may be performed more than 1m depending on the location due to the effect of avoiding shortage, avoiding shortage, and tending to look at the safer side, and waves, etc. If it is necessary to repeatedly press the ridges and the desired finished surface cannot be obtained, the excess part of the rubble can be removed using a claw grab or the like suspended on a gut crane. This has to be removed, which increases the number of finishing steps for the mound, lengthens the construction period, and increases construction costs.

本発明の目的は、かかる欠点を解決することにある。 An object of the present invention is to overcome such disadvantages.

In the present invention, a peak portion higher than the design plan height and a valley portion lower than the design plan height are formed on the main portion of the rubble mound, and a required arrangement is made such that the weight plate of the weight does not straddle a plurality of peaks. Each peak was pressed to roll to the design plan height. By making a peak higher than the design plan height and a valley lower than the design plan height, the rubble of the peak moves to the valley around it by the pressing of the weight, and the valley becomes lower, while the valley becomes Raised by the movement of rubble from the mountains,
As a result, the surface of the rubble can be inevitably located at the design plan height located at the height between the peak and the valley, so that the rubble mound can be efficiently and accurately finished. . In addition, since the weight plate of the weight is arranged so as not to straddle a plurality of ridges, when pressed in that state, one ridge can be pressed by the entire weight, and consolidation can be performed efficiently. By pressing one hill, the rubble of the hill can easily flow into the valley around the hill without any resistance, and the whole can be quickly flattened. Have.

In addition, since the compaction according to the present invention is performed from the center of the width to the outer edge, the rubble is moved toward the outer edge, that is, in the opening direction, so that the pressed area may be abnormally expanded. In addition to the absence, there is no outside edge, and the excess rubble moves to the outside of the width without any resistance, so that the compacting operation can be performed easily and efficiently.

In addition, every time pressing is performed in order to press toward the outer edge that is open from the width center part side, the excess rubble of the pressed part moves smoothly outward sequentially, minimizing the number of times of pressing. It also has the effect that it can be stopped.
