CAISSON AND METHOD FOR MANUFACTURING OF CAISSON WITH FRICTION INCREASED STRUCTURE

摘要

PURPOSE: A manufacturing method for a caisson having improved frictional force and a caisson thereof are provided to improve the stability of a caisson structure by improving resistance to the horizontal load of waves. CONSTITUTION: A manufacturing method for a caisson having improved frictional force is as follows. Two riprap filled parts(102) are formed in the bottom end of a caisson(100) touching with a riprap mound. The riprap filled parts are divided through a partition wall(103) and are filled with a large amount of ripraps(104). A riprap prevention part(106) is formed on the bottom surface of the caisson and prevents ripraps from being separated from the riprap filled parts.
