る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating mud dredged from the bottom of a sea, lake, or river.
【０００２】[0002]
【従来の技術】海や湖沼あるいは河川の水質汚染が進行
している場合には、かかる水質汚染の進行を阻止して良
好な環境を取り戻すことが生態系維持の観点できわめて
重要である。2. Description of the Related Art When water pollution of the sea, lakes, or rivers is progressing, it is extremely important from the viewpoint of maintaining an ecosystem to prevent the progress of water pollution and restore a favorable environment.
【０００３】水質汚染が進行する原因としては、外部か

を浚渫して除去してやるのが効果的である。[0003] The cause of the progress of water pollution is the inflow of organic matter from the outside and the elution of nutrients from the bottom mud. Therefore, in order to improve the water quality of lakes and marshes, the bottom mud is removed by dredging. Is effective.
【０００４】ところが、浚渫された泥土は含水比が高く
て強度が小さいため、そのままで処分することも再利用
することも難しい。そのため、かかる浚渫泥土に固化材
を添加して強度増大を図ることが必要不可欠となる。However, since the dredged mud has a high water content and a low strength, it is difficult to dispose or reuse it as it is. Therefore, it is indispensable to increase the strength by adding a solidifying material to the dredged mud.
【０００５】一方、浚渫される泥土は、一般的にはかな
りの容量となり、その処分場所を確保するのは容易では
ない。したがって、浚渫泥土の減容化を図ることがもう
一つの課題となる。On the other hand, the mud to be dredged generally has a considerable capacity, and it is not easy to secure a disposal place. Therefore, another challenge is to reduce the volume of dredged mud.
【０００６】[0006]
【発明が解決しようとする課題】しかしながら、含水比

量がさらに増加し、それを処理するために広大な用地を
確保しなければならないという問題を生じていた。However, in order to improve the strength of dredged mud having a high water content, a large amount of solidified material is required, so that the cost of the solidified material is high and the large amount of solidified material is added. This has further increased the capacity of the dredged mud, creating the problem of having to secure a vast area to treat it.
【０００７】本発明は、上述した事情を考慮してなされ

放置する。In the method for treating mud according to the present invention,
First, a slow-hardening material is added to the mud and stirred to form a mixed mud. Next, the mixed mud is filled in a water-permeable bag and left for a predetermined period.

わゆる超遅延剤と呼ばれる添加剤を使用すればよい。As the slow-hardening material, for example, a slow-hardening cement can be used. In particular, if it is blended so as to exhibit strength after several days, a sufficient dehydrating action can be expected during that time. . Specifically, for example, an additive called a so-called super retarder may be used which is used for integrating new and old concrete without causing a cold joint in a concrete joint.
【００１６】なお、脱水によって泥土の含水量が低下す

なくて済む。Since the water content of the mud is reduced by dehydration, the amount of the slow-hardening material added can be smaller than in the conventional case.
【００１７】透水性袋体は、泥土の重量に耐えられるも

含水量をより効率よく低下させることができる。During the standing, the arrangement of the water-permeable bag is optional. Even if the water-permeable bag is simply placed, a certain amount of dewatering can be performed by the weight of the mixed mud. If a predetermined load is applied, the above-mentioned dehydration action is promoted, and the water content of the mixed mud filled in the water-permeable bag can be reduced more efficiently.

水性袋体に十分な荷重を載荷することが可能となる。How to apply a load to the water-permeable bag filled with the mixed mud is optional. For example, a method of laying the soil on the water-permeable bag arranged so as not to overlap may be used. Although it is conceivable, if the water-permeable bags are stacked in several stages, a sufficient load can be applied to the water-permeable bags even in a relatively narrow space.

で、環境保護に大いに寄与する。The manner of disposing of the permeable bag that has been left to stand is arbitrary. The permeable bag may be transported to a predetermined waste disposal site and disposed of as it is. However, since predetermined dehydration is performed, There is little risk of chemical substances being eluted from the inside, and it has a certain strength, so if this is reused as embankment material, embankment material or landfill material, there is no need to secure a waste disposal site and It also contributes to environmental protection because it also reuses resources.

It is preferable to use a woven or non-woven fabric having a tensile strength of about 2 . Here, the water permeability is, for example, 10 −2 cm.
Those having water permeability on the order of / s are preferred.

る。When the water-permeable bags 11 filled with the mixed mud 8 are stacked and left to stand, water contained in the dredged mud 4 from the inside of the water-permeable bags to the outside. By the time the leaching and dredging mud 4 is solidified by the slow setting cement 7, the water content of the dredging mud drops to a certain level.

Is added and stirred to form a mixed mud 8, which is permeable bag 11
And the dredged mud 4 is leached from the water-permeable bag 11 before the dredged mud 4 is solidified by the slow-hardening cement 7. That is, the dredged mud 4 having a high water content is dehydrated to a certain level before the hydration reaction by the slow-hardening cement 7 starts, and thus the dredged mud is made in a state where the volume is reduced. 4 can be improved. In addition, since the water content of the dredged mud 4 is reduced by dehydration, the required amount of the slow-hardening cement 7 is smaller than in the conventional case.

と言える。If a method of adding a solidification material after mechanical dehydration such as a filter press is adopted, it is possible to reduce the volume of dredged mud and to save the solidification material as in the present embodiment. Considering that the equipment for performing the mechanical dewatering is large-scale, which requires additional installation and maintenance costs, the method for treating dredged mud according to this embodiment is extremely inexpensive and reduces the volume of dredged mud. It can be said that this is a useful method that can simultaneously achieve the saving of the solidified material.

となる。Further, according to the present embodiment, the permeable bags 11 filled with the mixed mud 8 are stacked during standing, so that the dewatering action is promoted and the water content of the dredged mud 4 is increased. In addition to being able to reduce the efficiency efficiently, even in a relatively narrow space, a sufficient load can be applied to the water-permeable bag body 11 to efficiently perform dehydration. This is a significant area reduction compared to the area required for solar drying.

You may make it dispose at a disposal site. In such a configuration, since the volume of the dredged mud is reduced to a predetermined level, the required capacity at the waste disposal site can be reduced. In addition, if the water-permeable bag 11 is left without being carried out and is filled with embankment or the like and greening is performed, it is possible to construct a park with moderate undulations.
