Description
Technical field
Factory building water-filling multi-layer box structure is shielded the present invention relates to a kind of three generations's nuclear power station.
Background technology
With greatly developing for China's nuclear power, the security and economy of nuclear power station become more and more important.Nuclear power station
Huge early stage construction cost is to restrict the key factor that nuclear power further develops.Nuclear power station early stage construction cost is essentially from two
Aspect, be on the one hand for improve security safety stock, on the other hand come from the longer construction period.Therefore, low cost
Honest and clean safety devices deposit and modular construction technology can significantly reduce the design and construction cost of nuclear power station, improve nuclear power
Competitiveness.The many casing shielding mill constructions of water-filling of the present invention not only increase the safety stock of nuclear power station, while realize again
Nuclear power station shields the modular construction of factory building, greatly shortens the construction period of shielding factory building, by low the building of nuclear power station
It is set as this.The structure type has significant meaning for improving nuclear power competitiveness.
The content of the invention
The invention aims to provide a kind of three generations's nuclear power station shielding factory building water-filling multi-layer box structure.
The object of the present invention is achieved like this：The basic outer surface of nuclear island factory building is provided with the casing knot of multilayer, annular
Filled with water under high pressure in structure, the cavity per layer box body inside configuration, and cavity is also associated with water tank aqueduct, above and below every layer box body
Two ends, which are additionally provided with the formed steel construction between formed steel construction, two layer box bodies, is injected with injection microdilatancy high-strength concrete, multilayer,
The outer surface of the body structure of annular is provided with external prestressing steel beam.
Present invention additionally comprises some such architectural features：
1. the total height of multi-layer annular body structure is highly consistent with nuclear island factory building basis.
2. described in water under high pressure be add radioactivity absorber water under high pressure.
Compared with prior art, the beneficial effects of the invention are as follows：It is special that the present invention is applied to large-scale three generations's nuclear power station structure
It is required that and need, realize nuclear power station and shield the modular construction of factory building, and nuclear power station is greatly improved resists outside thing
Security derived from part and internal waste heat.Certainly, while being also applied for large-scale storage tank, anti-collision structure, needing a large amount of water sources to go out
The structure of fire.
The present invention is to provide using three generations's Power Station With The Pressurized Water Reactors such as AP1000 nuclear power stations, " No. Hua Longyi " nuclear power station as
Object, for such design feature and functional requirement, proposes shielding factory building water-filling multi-layer box structure.This new structure is given up
Current nuclear power station shielding mill construction building prestressed reinforced concrete material；And use the empty van of steel reinforced concrete and steel construction
Structure, and will be injected added with the water under high pressure of radioactivity absorber in empty van cavity.Using solid circle shell knot shielding factory building now more
Structure, the circle shell structure stress is complicated, and the local failure of usual structure triggers structure integrally to destroy；The present invention uses water-filling cavity knot
Use and be welded to connect between configuration formula, casing.And multi-layer box structure is used, realizing the destruction of local casing does not influence it
His part-structure.The structure type of hull is introduced and be subject to this, developed on nuclear power station shielding mill construction.Together
When, using external prestressing technique, further improve the shock resistance and sealing of this structure.Water is applied to core by the present invention
In Power station structure, with important function and application, effect has three.Effect one：It is strong that cavity internal pressure water improves empty van structure
Degree and stability, reduce cost and improve the security and shielding of shielding factory building；Effect two, it is empty when external impact
Chamber water provide due to shock because hair fire fire extinguishing water source, i.e. impact damage triggers the destruction of casing, and water under high pressure is natural
Outflow, also by the probe and control system for setting fire-fighting bubble, the fire for nuclear island inside and outside provides safety guarantee.Effect
Three, be also nuclear power station it is peculiar the need for, i.e., nuclear power plant accident when residual heat of nuclear core system need it is a large amount of about 1500 tons~12000 tons
Water, this new structure can provide part water source.Construction method of the present invention is new, and the present invention is not required to cast-in-place mixed with tradition shielding factory building
Solidifying soil application work, and use batch production to make each piecemeal casing, this new structure is realized by the assembling or welding of casing.This
Cheap water and modular construction technology are applied in invention, have saved cost and duration, it is clear that with good economy.
