Specific embodiment
In order to be more clear the purpose of this utility model, technical solution and advantageous effects, below in conjunction with attached drawing and
Specific embodiment, the present invention will be further described in detail.It should be understood that described in this specification specific
Embodiment is intended merely to explain the utility model, is not intended to limit the utility model.
It please refers to shown in Fig. 1 to Fig. 5, the anti-aircraft impact structure of the utility model nuclear power plant comprising surrounded by exterior wall 10
Workshop and arcuate structure wall 20 that workshop top is set and the arcuated roof that 20 top of arcuate structure wall is set
30, it is provided with floor in workshop, arcuate structure wall 20 starts setting up from floor and to extending at the top of workshop, arcuate structure wall
Body 20 and exterior wall 10 and the arcuated roof 30 on top are all made of the connection type of consolidation.
Fly data and the anti-aircraft impact design warp of existing nuclear power engineering of landing according to existing large commercial aircraft impact
It tests, for usual aircraft in low-latitude flying, the maximum angle of airframe axis and horizontal plane is 10o.By using arcuate structure
Design after arcuate structure wall 20 or arcuated roof 30 are hit in plane nose part, is decomposed due to the deflection of globoidal structure and is made
With hitting arcuate structure by initial tilting down and be changed into inclination upwards and fly away from arc knot so that airframe structure rotates
Structure；Airframe structure lateral impact arcuate structure simultaneously causes the fuselage cross-section for hitting part to become ellipse from approximate circle；It is main
Wing and engine are affected by the influence of arch cambered surface, will not cause vertical direction toward impact to structure；Aircraft impact arcuate structure
Process " ricochet " phenomenon that may occur when being similar to Oblique penetration, aircraft can be effectively reduced to the impact energy of structure
Amount.
It please refers to shown in Fig. 2 and Fig. 3, exterior wall 10 is plane wall, external walls or periphery usually not landform or builds
It builds object to block, the shock of aircraft cannot be resisted, therefore need to protect roofing or the naked wall being exposed on the external, prevent aircraft from hitting
It hits.
The top of exterior wall 10 is arranged in arcuate structure wall 20, curved wall V2, V3 including the setting of exterior wall 10 along workshop
And V4, in the shown embodiment, because of wall V1 and the public wall of Adjacent Buildings, wall V1 is planar walls.Arcuate structure wall
Reinforcing bar (not shown go out) is provided in body 20, and Bar Anchorage, in the floor in workshop, floor should be according to the arrangement feelings of power plant
Condition is configured, and the support wall connecting of floor and its periphery, in addition slab thickness should meet the thickness of curved wall Bar Anchorage
Degree requires.
Further, the radius of arcuate structure wall 20 is 20~30m, with a thickness of 1~1.5m.In the provisioning process, arc
Shape structure wall 20 can be configured according to the actuality of aircraft impact, while consider the convenience and mechanical characteristic of construction, and one
As since at floor, guarantee the reliable delivery of structure stress, in addition can give full play in the drag and knockout process of structure
Deflecting effect, arcuate structure wall 20 setting height can also according to need to protect workshop height and its periphery workshop height come
It determines.
The application region of arcuate structure wall 20 can determine according to the General Arrangement Scheme of nuclear power plant, usually can be in safety
It is arranged in shell and its periphery workshop.
It please refers to shown in Fig. 3 to Fig. 5, arcuated roof 30 is unsymmetric structure, the tangent line of arcuated roof 30 and horizontal plane
Angle α is not more than 30o, the thickness h of arcuated roof 30 is 0.8~1.2m, and span is 20~30m.Aircraft can be effectively realized to hit
