Title: Water-tight joint section structure of submerged case
Inventor: KIKUCHI AIKO
IPC: E02D29/063
Filed: 1995-02-09
Abstract: PURPOSE: To reduce the deformation amount of a water-tight rubber and improve maintainability of a water-tight joint section by providing a plurality of coil springs along a front end face and a rear end face of a double shell and preventing external force other than force for maintaining water-tightness from acting on the water-tight rubber. CONSTITUTION: When a case is submerged and excessive compression force 7 acts on a double shell 01a due to earthquake, a coil spring 6 supports it. Accordingly, a water-tight rubber 3 which is sandwiched between an overhanging plate 1 for mounting and an overhanging plate 5 for compression to stop water receives water pressure based on water depth at the installation place and is merely deformed slightly. Moreover, since a pleated steel plate 07 supports shearing force of the double shell 01a in the vertical direction and the forward and backward directions, large compression force does not act on the water-tight rubber 3. By the way, if water depth of the water-tight rubber 3 is 25 meters, water pressure which acts on it is about 2.5kgf/cm<2> .  Furthermore, when excessive tensile force 8 acts due to earthquake at the time of the construction of the submerged case, the coil spring 6 supports it. Accordingly, the water-tight rubber 3 receives water pressure based on water depth at the installation place and is merely deformed slightly. As for the other circumstances, it is the same as the above.

Abstract: PURPOSE:To make it easy to separate steam and water and supply steam which is highly dry by providing a plate member with gaps along the circumferential face at the lower section on the inside of a separation cylinder which is provided with a steam outlet pipe at the upper end section, steam introduction pipe on the side wall section, and a down comer at the lower end. CONSTITUTION:A steam introduction pipe 2 is connected to the side wall section of a separation cylinder in the direction tangential to the side wall section. The separation cylinder 1 is rotated to separate liquid drops and dry steam is supplied from the steam outlet pipe 3 at the upper section of the cylinder. A pipe 4 for the descending water is connected to the lower end section of the separation cylinder 1 and in the upper section a gap 5 for introducing the separated water is formed and a plate member 6 is provided which has a rotation prevention vane member 14. Since the separated water is discharged through the gap 5 from the circumferential wall section which has a higher pressure than the central section, the water discharge is smooth and an excellent air and water separation is achieved. It is, therefore, possible to supply stably highly dry steam.
