CONSTRUCTION METHOD OF SUBMARINE VERTICAL WATERWAY FOR SUPPLYING AND DISCHARGING COOLING WATER FOR INDUSTRIAL FACILITIES UTILIZING JACK UP BARGE AND GUIDE FRAME AND INNER CASING AND CASING CLAMP

摘要

The present invention relates to a method for constructing a marine vertical sphere for deep intake and drainage of cooling water for industrial facilities using a jack-up barge and a guide frame, and more particularly, to a bottom dredging step, a jack-up barge installation step, and the jack-up barge. Guide frame installation step, installation of steel pipe on the guide frame and fixing the steel pipe and dredging surface, installing the casing clamp on the upper portion of the steel pipe, mounting the excavator to the casing clamp and excavating the dredging surface, the inner of the dredging hole Offshore in the seabed consisting of rock or sandstone layers through the first step of inserting the casing, mortar injection to the outside of the inner casing, cutting the lower end of the steel pipe, excavation of drainage tunnels, mounting of the heavy structure and sandstone reclamation and covering stone laying step Provides methods and equipment for constructing vertical spheres.
