Abstract
The utility model relates to a water retaining structure for a coast nuclear power plant, particularly to a water retaining wall at an important factory water overflow well. The water retaining wall is positioned between an overflow passage of the important factory water overflow well (1) and a revetment (4) and is divided into a fixed part and a detachable part; the detachable part is positioned on the overflow passage of the overflow well (1). When the nuclear power plant is in a normal operating state, the detachable part is dismounted, and the traffic and the important factory water overflow passage are not affected. Under the condition that seawater may get over the revetment (4), the detachable part is quickly assembled to the fixed part of the water retaining wall, so that a second water detaining wall at the back of the revetment (4) is formed to stop seawater from entering the factory and ensure flood control safety of the factory. The retaining wall can be widely applicable to coast nuclear power plants.
Description
Technical field
The utility model relates to a kind of Coastal Nuclear Power Plant water-retaining structure, is specifically related to a kind of waterwall for essential service water overflow well place.
Background technology
Nuclear power plant's essential service water overflow well can guarantee, in nuclear power plant, extreme external event occurs, as when extreme earthquake occurs, the overflow well rear line wrecks and causes the essential service water draining can't be when after overflow well, important water drainage pipe enters sea, essential service water overflows ground by overflow well, by overflow ducts through ground discharged to sea, guarantee that the essential service water overflowed can not be back to plant area, avoids plant area to suffer water logging.
And Coastal Nuclear Power Plant all directly faces sea, when extreme flood event occurs in off-lying sea, the flood level of off-lying sea reaches design protection peak level, now consider the impact of typhoon, the wave of off-lying sea is typhoon, seawater can be under the effect of typhoon, and part is crossed plant area's shore protection and entered plant area, threatens plant area's safety.By increasing shore protection, can play the effect that stops that seawater that typhoon causes enters, but, because instantaneous typhoon can be very high, so just require shore protection to increase a lot, thereby affect the economy of whole nuclear power plant.In existing situation, realize that shore protection is more not unrestrained fully, stop that it is unpractical that seawater that typhoon causes enters plant area.
Summary of the invention
The purpose of this utility model is to provide a kind of waterwall for Coastal Nuclear Power Plant essential service water overflow well place that stops typhoon to enter plant area.
For realizing that the utility model purpose technical scheme is as follows: a kind of waterwall for Coastal Nuclear Power Plant essential service water overflow well place, between nuclear power plant's essential service water overflow well and shore protection, be divided into standing part and removable section, and removable section is positioned on the overflow ducts of overflow well.
The waterwall that the utility model provides is between overflow well and shore protection, and under nuclear power plant's normal operating condition, removable section is removed, and traffic and essential service water overflow ducts are all unaffected; When extreme flood and typhoon occur in sea, the active blocking waterwall can be realized interim rapid-assembling, with two sections standing parts of concrete waterwall, forms the associating waterwall, guarantees that the seawater of crossing shore protection is stopped by waterwall, make it not enter plant area, guarantee plant area's flood control safety.With respect to the transformation shore protection, its difficulty has significantly and to reduce, and the economy of design also improves greatly, can reduce to a certain extent and increase the impacts such as power plant's view of bringing and vision due to shore protection simultaneously.
Further, described standing part comprises two section concrete waterwalls, is positioned at the two ends of waterwall; Removable section is between two section concrete waterwalls, and the overflow ducts of width and overflow well adapts.This structure, when stoping seawater to enter plant area, has more effectively reduced the impact that the traffic of overflow well overflow ducts and overflow water are flowed out.
Further, in the inner of two section concrete waterwalls, be respectively equipped with fixed guide, described detachable part is divided into the dash plate that guide rail can be inserted in both sides.This structure can make the dismounting of waterwall and install more fast and convenient, and especially in the situation that obtain the information that seawater may be crossed shore protection, the establishment that completes this waterwall within the very first time is particularly important.
Further, be provided with at least one slot on the ground between two section concrete waterwalls; Described removable section also comprises corresponding with slot quantity and the movable guiding rail of a pair of opposing guide groove arranged, and described dash plate is also corresponding is provided with several.This structure can prevent that single dash plate is excessive and bring installation and removal inconvenience.
The accompanying drawing explanation
Fig. 1 is nuclear island master plant area, essential service water overflow well and sea position view.
The dismounting schematic diagram of the specific embodiment that Fig. 2 provides for the utility model.
In figure, 1-overflow well, 201,202-dash plate, 301,302-concrete waterwall, 4-shore protection, 501, the 502-fixed guide, 6-movable guiding rail.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to more specific detail.
As depicted in figs. 1 and 2, a kind of waterwall for Coastal Nuclear Power Plant essential service water overflow well place, between shore protection 4 and overflow well 1.Waterwall is divided into standing part and removable section, standing part is concrete fixed permanent structure, be divided into discontinuous two section concrete waterwalls 301,302, lay respectively at the both sides of overflow well overflow ducts, in two section concrete waterwall 301,302 relative ends, be respectively equipped with vertical fixed guide 501,502.Removable section comprises a movable guiding rail 6 with a pair of opposing guide groove, and movable guiding rail 6 height are identical with fixed guide 501,502, and movable guiding rail 6 assigns in ground slot.Removable section also comprises that dual-side inserts respectively the dash plate 201,202 in fixed guide and movable guiding rail guide groove, and dash plate 201,202 width are corresponding to the distance between fixed guide 501,502 with movable guiding rail 6.The width of whole removable section adapts with the width of overflow well 1 overflow ducts.
Above-mentioned embodiment and accompanying drawing 1 are depicted as the state of the utility model when seawater will be crossed shore protection, if there is seawater to cross shore protection, can play the effect that stops seawater to enter plant area.After flood control is removed, the dash plate of active blocking waterwall is removed piecewise, and movable guide rail is removed, and the essential service water overflow ducts is unimpeded, and it is unimpeded that traffic recovers.
Obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the claims in the present invention and equivalent technology thereof, the utility model also is intended to comprise these changes and modification interior.
