Description
<p> We have devised the on-site reforming method with a ground improvement ship to improve a seabed clay ground by mixing steelmaking slag at the original position. In order to improve the mixability of the clay with water content close to the liquid limit, we have improved mixing equipment in the bucket attached to the ship. As a result of experiments on a 1/5 scale model to evaluate effectiveness of improved mixing equipment, the improved equipment was found to be able to disperse slag evenly in the clay in a shorter mixing time than the conventional equipment. Moreover, for clay with a water content of 1.1 times or more the liquid limit, the variation in strength of improved clays was reduced to the same level as clay with a high water content. However, in the case of clay ground where the natural water content is below the liquid limit, it is necessary to extend the mixing time or to add water to the clay in the bucket.</p>
