In the present invention, the high strength concrete making described bottom tank body can adopt prestressed light high strength concrete.
Above-mentioned marine nuclear power platform, the displacement of described bottom tank body equals the total weight of described marine nuclear power platform;
When using cement concrete of the present invention sea nuclear power platform, the suck sediment subsidence that breaks ground, the crowded methods such as sinking, diversion descending or negative pressure sinking of becoming silted up of overload can be adopted in place, namely can realize the function of certainly installing; By controlling the seawater injection rate of ballast tank in the tank body of described bottom, the ballast adjusting the marine nuclear power platform of described cement concrete sinks.
The tank body of bottom described in the present invention when towage for marine nuclear power platform provides buoyancy, when described marine nuclear power platform sinks, in described ballast tank, inject seawater, increase the weight of described nuclear power platform, make whole platform weight be greater than the displacement of described bottom tank body; When described marine nuclear power platform is floated, the seawater of draining in described ballast tank, reduce the weight of described nuclear power platform, the total weight of whole marine nuclear power platform is made to be approximately equal to or less than greatly the displacement of described bottom tank body, namely weight is suitable with buoyancy, center of gravity overlaps vertical with centre of buoyancy, returns to land carry out reloading and overhaul to guarantee that described marine nuclear power platform can regularly be shifted.
Compared with prior art, the present invention has the following advantages:
(1) marine nuclear power platform can float, and returns to base, land and reloads, improve safety after displacement.
(2) shape of bottom tank body arranges the ability made it have in ice formation operation.
(3) can realize, from installing, reducing executive cost.
(4) marine nuclear power platform adopts concrete tank body structure, and cost is lower, long service life.
(5) nuclear island (reactor) is placed in underwater, and arranges the valve with seawater UNICOM, during emergency situation, seawater will enter tank body, substantially increase the safety of emergent operating mode.
(6) space of tank body is controlled, can install multiple nuclear island, and the facility location of its inside is comparatively easy.
