METHOD OF LAYING A FOUNDATION FOR A STRUCTURAL ELEMENT UNDER WATER

摘要

Under a structural element and around a supply place a crater is made by laying a dike of foundation material in the space under the structural element and around the supply place and the space around said crater is subsequently filled up with foundation material by supplying suspension of foundation material with water into the crater and by causing it to flow over the edge of said crater. With this method the edge of the crater grows gradually so as to form a continuous layer of foundation material. The suspension of foundation material with water flowing over the edge of the crater is heavier than silt found around the crater resulting in the suspension driving the silt before it out of the space without being mixed with the silt.
