<p>In order to set a unit structure on a soft sea bed, it is necessary to reform the soft sea bed by injecting a cement-containing hardening agent thereinto and kneading the mixture of the hardening agent and the earth in the sea bed, for the purpose of preventing a building to be constructed on the unit structure from being displaced or deformed due to the load on the unit structure and the horizontal load. A unit structure is set on such a reformed sea bed, and used for the drilling of an experimental oil well and the production of oil at sea.</p> |
