Description
Technical field
The utility model relates to the nuclear plant safety field, relates in particular to the anti-whipping structure of high energy pipeline in a kind of conventional island factory building.
Background technology
Anti-whipping structure is distinctive a kind of structure in nuclear power station conventional island, and it is in order to prevent that the impact force that produces after the pipeline breaking of conventional island high energy from causing the pipeline whipping so that affecting nuclear island factory building safety and the limiting structure of setting.At present, the general anti-whipping structure of high energy pipeline of usage comparison all adopts steel frame supporting structure, but the design of this class formation and construction are all comparatively complicated, and is only applicable to the situation of three pipe arrangement comparison rule; As depicted in figs. 1 and 2, when the layout of high energy pipeline 10 during irregular or load situation more complicated (R1 in figure, R2, R4, R5, R6, R1B, R2B, R4B, R5B, R6B are whipping point of load application position), existing steel frame supporting structure just can't be suitable for.
In view of this, necessary designing a kind ofly can be applicable to the layout of complicated high energy pipeline and the anti-whipping structure under the whipping load action.
The utility model content
The purpose of this utility model is: provide a kind of and can be applicable to the layout of complicated high energy pipeline and the anti-whipping structure under the whipping load action, to guarantee the safety of nuclear island factory building.
To achieve these goals, the utility model provides a kind of anti-whipping structure of nuclear power station high energy pipeline, and it adopts shear wall opposing whipping power, described shear wall at all whipping points of load application places all perpendicular to the axis direction of high energy pipeline.
As a kind of improvement of the anti-whipping structure of the utility model nuclear power station high energy pipeline, described shear wall is concrete shear force wall.
As a kind of improvement of the anti-whipping structure of the utility model nuclear power station high energy pipeline, the foundation of described concrete shear force wall is connected with conventional island factory building agent structure, and throw off with conventional island factory building agent structure on top.
As a kind of improvement of the anti-whipping structure of the utility model nuclear power station high energy pipeline, described shear wall comprises two parts at least independent of each other, and is spaced apart by the Vierendeel girder of conventional island factory building between each several part.
Compared with prior art, the utility model adopts and resists whipping power perpendicular to the shear wall of high energy conduit axis direction, has effectively simplified the design work of engineering pipe arrangement and civil engineering structure.
Description of drawings
Below in conjunction with the drawings and specific embodiments, anti-whipping structure and the useful technique effect thereof of the utility model nuclear power station high energy pipeline is elaborated, wherein:
Fig. 1 is the axonometric drawing of certain specific high energy pipe arrangement.
Fig. 2 is the plan view of high energy pipe arrangement in Fig. 1.
Fig. 3 is the floor map of the anti-whipping structure of the utility model nuclear power station high energy pipeline when being used for high energy pipeline shown in Figure 1.
Fig. 4 is the layout schematic diagram of the shear wall at two places in Fig. 3 when linking together.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and useful technique effect thereof more clear, below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.Should be understood that, the specific embodiment of describing in this manual is only in order to explain the utility model, is not in order to limit the utility model.
See also Fig. 3, the anti-whipping structure of the utility model nuclear power station high energy pipeline adopts concrete shear force wall 20,22 to replace steel frame to resist whipping power, concrete shear force wall 20,22 at all whipping point of load application R1, R2, R4, R5, R6, R1B, R2B, R4B, R5B, R6B place all perpendicular to the axis direction of high energy pipeline (because the conduit axis at whipping point of load application R2, R2B place is vertical direction, its corresponding concrete shear force wall 20,22 is horizontal direction, so fails to illustrate the concrete shear force wall of 2 correspondences therewith in the plan view of Fig. 3).Large due to anti-side rigidity in concrete shear force wall 20,22 face, Out-of Plane Stiffness is less, so at the body of wall of each point of load application location arrangements perpendicular to pipeline, can effectively utilize the effect of the characteristic opposing whipping load of shear wall, thereby realize the anti-rejection of all whipping points of load application.As seen, compare with traditional steel frame supporting structure, concrete shear force wall 20 of the present utility model, 22 structure constructions are simple, coordinate also simply with the technique specialty, need allow high energy pipeline 20 directly pass body of wall and get final product.
If above-mentioned concrete shear force wall 20,22 and conventional island factory building agent structure building be an integral body, conventional island factory building agent structure will become the frame shear wall structure system by frame structure system originally, but because concrete shear force wall 20,22 is arranged very irregular in whole conventional island factory building, only be arranged in end bay, concrete shear force wall 20,22 construction will certainly cause very large torsion to conventional island factory building agent structure, and the utmost point is unfavorable for antidetonation; Therefore, in order to reduce the antidetonation torsion effect, must also arrange shear wall structure in the other parts of conventional island factory building agent structure, this will increase the workload that coordinates with other technique specialty greatly, can greatly reduce simultaneously the permeability of factory building.For fear of above-mentioned deficiency, the utility model is set to concrete shear force wall 20,22 only, and foundation is connected with conventional island factory building agent structure, the form that throw off with conventional island factory building agent structure on top, thus layout and the design work of conventional island factory building agent structure greatly simplified.
In addition, as can be seen from Figure 3, the whipping point of load application all concentrates on two places: the first place is between C and D axle, and another place is between B and C axle; If according to Traditional Thinking, shear wall 20,22 with two places utilizes connection wall 24 to link together as shown in Figure 4, will there be so following two problems: first, in order to guarantee shear wall 20,22 structural independence, Vierendeel girder on the C axle just can not arrange, this will weaken the integral rigidity of conventional island factory building agent structure; The second, the effect that is connected in the 24 pairs of opposing whipping power of connection wall between two places is little, and its construction can cause unnecessary waste on the contrary.Therefore, the utility model is broken through conventional, and the shear wall 20,22 at two places is arranged independently of one another.
In sum, the utility model adopts and resists whipping power perpendicular to the concrete shear force wall 20,22 of high energy conduit axis direction, has effectively simplified the design work of engineering pipe arrangement and civil engineering structure; And the top of guarding against throw structure and conventional island factory building agent structure is thrown off, make and both can separately carry out modeling work, and need not consider the adverse effect of shear wall 20,22 pairs of conventional island factory building agent structure antidetonations.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this manual, these terms do not consist of any restriction to the utility model just for convenience of description.
