Description

  The present invention relates to a suspended curtain wall water barrier membrane assembly, and more specifically to a suspended curtain wall water barrier membrane assembly suitable for use in, for example, a cooling water intake used in a power plant. .

  In power plants such as thermal power plants and nuclear power plants, a turbine generator is driven by steam flow to generate electricity. Since the power generation turbine rotates by the difference between the steam pressure at the entrance and the steam pressure at the exit, it is essential to lower the steam pressure at the exit by returning the steam flow after driving the turbine generator to water. For this reason, before returning a steam flow to a boiler installation or a nuclear reactor, in many cases, this steam flow is cooled to water by a condenser using seawater as cooling water.

  Therefore, the cooling water is taken in the sea area close to the power plant, and the relatively low temperature sea water taken is stored in a storage pool or a condensate storage tank for use. At this time, it is preferable that seawater as cooling water is taken from relatively deep seawater at relatively low temperatures. By removing relatively shallow seawater, which is relatively shallow, and selectively using relatively low temperature seawater, turbine efficiency is improved. The impact will be reduced and it will be possible to eliminate the inflow of floating dust, pollutants, plankton, shellfish and other power plants contained in relatively shallow seawater.

  In the present application documents, the terms “deep water” and “deep water” are generally called deep water, and only a portion of seawater deeper than the depth of about 200 m, which has been used for beverages in recent years, is limitedly designated. I'm not. It should be noted that this is a broad concept including not only seawater generally called deep water but also seawater in general with relatively deep water and relatively low water temperature.

  Conventionally, when a cooling water is taken from the ocean, a gravity type water intake is known as a water intake for selectively taking relatively deep low-temperature seawater. The conventional gravity-type water intake has a rigid structure that receives and supports the wave force acting on the water-impervious plate by the piles.

  For example, in FIG. 4 and FIG. 5 of the following Patent Document 1, two types of gravity wall type curtain wall type water intake pile structures as shown in FIG. 1 and FIG. 2 of the accompanying drawings are introduced. Here, reference numeral 3 is a curtain wall, 4 is a water shielding plate (PC plate), 5 is a steel pipe pile, and 6 is bottom plate concrete.

  “Rigid structure” refers to a structure such as a breakwater that has a function of maintaining a stationary state against wave energy and preventing propagation of the reached wave. In order to realize this gravity-type water intake with a rigid structure, a large-scale and robust pile driving work and a robust water-impervious plate are required, and the time and cost required for the construction are also very high. It was a big one.

  However, the function required as a water intake is not a function of blocking the propagation of waves that have reached, but a function of selectively taking in relatively low-temperature seawater. Therefore, it is unnecessary to construct a rigid structure that blocks the propagation of waves that have reached the water intake, considering the original purpose.

  Therefore, it has been proposed that the structure of the intake port be a curtain wall impermeable plate having a flexible structure in which the impermeable plate swings along with the arriving waves to allow transmission of wave propagation.

  Here, the “soft structure” refers to a structure that is in a movable state following the wave energy and has a function of substantially transmitting the propagation of the reached wave.

Here, “curtain wall” is a term in the field of architecture, and is an outer wall made by assembling factory-produced parts on site, and supports the load with a wall like a reinforced concrete building wall. Refers to a wall that does not have In other words, the term “curtain wall” is a concept for a bearing wall, and the meaning of a prefabricated outer peripheral wall is established as the building becomes taller. In turn, in the present application document, the water-insulating member of the water intake port is used for a pre-fabricated water-insulating member having no role of supporting a load.
The inventors of the present application filed as Japanese Patent Application No. 2001-280197 on September 14, 2001, and the application was published on March 28, 2003 as Japanese Patent Application No. 2003-90029. We are aware of the name of the invention “water intake for cooling water”.

  As described above, the conventional rigid curtain wall type water intake requires a large-scale and robust pile driving work, and therefore, the number of days and cost required for the work are very large. By adopting a simple flexible curtain wall intake with the function of selectively taking relatively deep low-temperature seawater, the number of construction days and costs can be greatly reduced. It was hoped that.

  The “water intake for cooling water” disclosed in the above-mentioned JP-A-2003-90029 is a kind of curtain wall type water intake having a flexible structure. 1 and 2 of Japanese Patent Laid-Open No. 2003-90029 introduce a curtain wall type water intake having a flexible structure as shown in FIGS. 3 and 4 of the accompanying drawings. Here, reference numeral 2 is a waterway entrance (corresponding to the “reservoir pool” of the present application), 7 is a water shielding plate (PC version), 8 is a pivot, 9 is an anchor (box culvert), and 10 is for deep water intake. , 11 is a pivot part, 12 is a floating body, and 13 is a connecting member.

  However, subsequent studies by the present inventors have revealed that various structures can be realized in a flexible curtain wall intake.

  Also, when researching various flexible structure curtain wall intakes, the structure of the water shielding plate, the means for positioning the water shielding plate, the ease of construction, the ease of changing the height of the water intake, In terms of ease of maintenance management, it has been found that there are features, advantages, etc. that cannot be realized with other flexible curtain wall intakes.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a suspended curtain wall water shielding film assembly according to the present invention will be described below in detail with reference to the accompanying drawings.

  First, a general overview is provided so that the image of the suspended curtain wall water barrier membrane assembly can be easily grasped.

  FIG. 5 is a plan view of the suspended curtain wall impermeable film assembly 20 as seen from above, FIG. 6 is a front view, and FIG. 7 is a cross-sectional view as seen from the II direction of FIG. The suspended curtain wall water barrier membrane assembly 20 is installed near the land, typically at the bottom of the sea. In FIG. 5, the upper side of the drawing is the offshore direction of the ocean 38 and the lower side is the direction of the land 39. The direction of the arrow is the direction in which the waves push. Two rows of revetments 21 and 22 are constructed generally parallel to the direction in which the waves come, and a suspended curtain wall impermeable membrane assembly 20 is installed between these revetments.

  The suspended curtain wall impermeable membrane assembly 20 positions the impermeable member at a desired height from the seabed to prevent inflow of shallow water and form a water intake for selectively taking in deep water. Therefore, it is necessary to position the water-impervious member at a desired height h in the sea by appropriate positioning means.

  As shown in FIG. 6, in this embodiment, the water shielding member for blocking the inflow of the shallow water is the water shielding plate 25 (the unit is indicated by reference numeral 25-1) and the water shielding film 26 (the unit is indicated by reference numeral). 26-1)). A lower end portion 27 of the water shielding film 26 is positioned at a predetermined height h from the sea bottom 28, and a water intake 31 for selectively taking in only relatively deep water at a relatively low temperature is formed.

  As shown in FIG. 7, both the water shielding plate 25 and the water shielding film 26 constituting the water shielding member have a structure that can swing according to waves.

  After the entire image has been grasped, an embodiment of the suspended curtain wall water-proof membrane assembly 20 will be described in detail with reference to the drawings. As shown in the plan view of FIG. 5, two rows of revetments 21 and 22 are constructed in a direction generally perpendicular to a coastline (not shown). The revetment is not limited to two rows. As shown in FIG. 10 (A), three rows of revetments or more than one row of revetments may be used. Referring to FIG. 5 again, between these revetments 21 and 22, a suspended curtain wall impermeable film assembly 20 is installed in a direction generally perpendicular to the wave approaching direction indicated by an arrow. As shown in the drawing, the ocean 38 is above the suspended curtain wall impermeable film assembly 20, and the water storage pool 29 for storing deep water is formed together with the revetments 21 and 22 below. In addition, since the water shielding film assembly 20 is very long, for example, several hundred meters, a part thereof is omitted in the drawing.

  As shown in FIGS. 5 and 6, the essential function of the suspended curtain wall impermeable membrane assembly 20 is to prevent relatively shallow seawater from flowing from the ocean 38 to the reservoir pool 29, The purpose is to selectively flow relatively deep seawater at a relatively low temperature. In order to carry out this, a water-impervious member is provided, and the lower end portion thereof is positioned at a desired height h from the seabed to ensure a water intake depth (water intake height). It is necessary to prevent the inflow of shallow water so as to cover the sea surface. As shown in FIG. 7, the sea level 35 has a high water level H. W. L. (High water level) and low tide water level W. L. (Low water level) is changing cyclically, especially at low tide level L. W. L. At this time, it is important to design the intake 31 so as to ensure a predetermined height h.

  As shown in FIG. 6, in the present embodiment, the water shielding member includes a water shielding plate 25 and a water shielding film 26. The water shielding plate 25 functions as a floating means (floating body), and the water shielding film 26 is suspended from the water shielding plate 25. In order to secure the desired water intake 31, the lower end portion 27 of the water shielding film 25 is positioned at a desired height h from the seabed 28. The water shielding plate 25 is configured by connecting a plurality of water shielding plates alone (hereinafter also referred to as “floating bodies”) 25-1 in the horizontal direction. Similarly, the water shielding film 26 is configured by connecting a plurality of water shielding film single bodies 26-1 in the lateral direction.

  Although the structure of the water shielding plate unit 25-1 which is a floating body is not illustrated, for example, the outer wall and the partition wall are made of lightweight aggregate concrete, and the interior space is filled with foamed polystyrene. Mainly, the floating body is adjusted so as to have a predetermined weight by the amount of light aggregate concrete used and filled with expanded polystyrene to prevent the occurrence of buoyancy reduction due to the flooding of seawater into the floating body. Depending on the weight of the water shielding plate 25, a resonance phenomenon is caused by the wave period, and the suspension curtain wall water shielding film assembly 20 is damaged, so that the resonance phenomenon does not occur. Since the water shield plate 25-1 can be replaced, preparing the water shield plate 25-1 of various weights in advance makes it possible to shield the weight that does not cause resonance even with different wave periods. A water plate can be selected and used. It has been found that if the floating body is configured to have a minimum width and a minimum height so that the floating body does not become unstable, the wave force received is reduced.

  A plurality of such water shields 25-1 are prepared and arranged in a row in the horizontal direction so as to block the inflow of relatively hot seawater in the shallow layer. The water shields 25-1 adjacent to each other are connected to the revetments 21 and 22 (see FIG. 5) adjacent to the water shields 25a and 25b adjacent to each other. Each is connected to form a water shielding plate assembly 25 between both revetments. As a connection means between adjacent water shielding plates (floating bodies) 25-1, for example, a connection member 33 such as a chain or a wire is used. It is preferable that this connection means improve the corrosion resistance against seawater by taking anticorrosion measures such as cathodic protection and plastic coating as necessary.

  In order to prevent water leakage between adjacent water shielding plates connected by a chain or the like more reliably, a flexible water shielding connection member (not shown) that can follow the movement of both water shielding plates is provided between both water shielding plates. Further, it may be attached.

  It is desirable that the connecting means 33 of the water shielding plate 25-1 can be freely released. By releasing the connecting means 33, it is possible to replace the water shield plate unit 25-1 in units. Moreover, since each floating body 25-1 shakes independently according to a wave, adjacent water-shielding plates may collide and may be damaged and destroyed. In order to avoid such collision breakage, it is preferable to attach an impact-proofing material, an impact-absorbing material, etc. (not shown) to areas such as corners and surface parts of each water shielding plate.

  The water shielding film 26 basically has a waterproof function, and any material can be used as long as it has a strength capable of withstanding wave power. A water barrier membrane assembly 26 comprising a plurality of water barrier membranes 26-1 is arranged by connecting a plurality of water barrier membranes in a row so as to block the inflow of relatively hot seawater in a shallow layer. Is done. The connecting means may integrally form a water shielding film by sewing, or may be connected so as to be separable using a fastener or the like as shown in the figure. If the connecting means is separable, the damaged water shielding film 26 can be replaced with the water shielding film alone 26-1.

  As shown in FIG. 7, the water shielding film single unit 26-1 is suspended from the water shielding plate unit 25-1 by an appropriate suspension means 40 so as to be freely swayed. The suspension means 40 is preferably separable. If separable, only one of the water shielding film 26-1 or the water shielding board 25-1 can be replaced as desired. In order to reduce water leakage between the water shielding plate unit 25-1 and the upper end portion 30 of the water shielding film unit 26-1, a recess is provided on the bottom surface of the water shielding plate unit 25-1, and the suspension means 40 and the upper end portion are provided. 30 may enter the recess. In the case shown in FIG. 6, two single water shielding films 26-1 are suspended with respect to one single water shielding plate 25-1, but this ratio is arbitrary. Thus, the shallow seawater is prevented from flowing from the ocean 38 to the water storage pool 29 over the height of the water shielding plate 25 and the height of the water shielding film 26 (hb + hf). The distance between the lower end 27 of the water shielding film 26 and the sea bottom 28 is adjusted to a desired height h of the water intake 31.

  As shown in FIG. 6 to FIG. 8, at least one or more of the actual water shields 25-1 are actually connected to the sea floor 28 by mooring lines 32, and the suspended curtain wall water barrier membrane assembly 20 is formed. Moored between revetments 21 and 22. The mooring line 32 is typically formed from a chain. However, the weight of the chain is relatively large, so if the buoyancy of the floating body itself is small, the height of the freezer will be significantly reduced, so it is also possible to use a wire rope with a small weight, such as a locked coil rope. I can do it. Any mooring line 32 is preferably subjected to anticorrosion measures such as cathodic protection and plastic coating as necessary to improve the corrosion resistance against seawater.

  As shown in FIGS. 6 and 7, the mooring line 32 has one end connected to a floating body (water shielding plate alone) 25-1 and the other end connected to an anchor 9 fixed to the seabed 28. The anchor 9 only needs to be able to securely lock the water shielding plate 25-1 to the sea floor 28 via the mooring line 32, and is made of a concrete block, for example.

  If desired, an intermediate sinker 34 may be provided in the intermediate portion of the mooring line 32. The intermediate sinker 34 is a weight that surely sinks in the sea (or underwater). For example, an iron sinker can be used. By providing the intermediate sinker 34, the floating body 25-1 is allowed to flow in a certain range while applying more tension to the floating body 25-1 before the mooring line 32 reaches the maximum tension state. To come. Thus, by providing the intermediate sinker 34, the reaction force characteristic of the line when the mooring line 32 is pulled can be enhanced.

  The action of the floating body and the water shielding film will be described together. As shown in FIGS. 7 and 8, the water shielding plate 25 also functions as a floating body and swings following the waves. Further, since the adjacent water shielding plate units 25-1 are simply connected to each other by the connecting members 33 such as chains and wires, the degree of freedom of movement of each of the water shielding plate units 25-1 is ensured. It can follow and swing independently. For this reason, compared with the case where the whole water shielding board (floating body) assembly 25 is integrally formed, it seems that the wave energy is followed and swayed and wave energy is transmitted more efficiently. Further, as shown in FIG. 7, since the water shielding plate unit 25-1 and the water shielding film unit 26-1 are connected by a swingable suspension means 40, the water shielding plate, the water shielding film, Can be upset independently. Furthermore, since the water shielding film unit 26-1 itself suspended from the water shielding plate unit 25-1 is made of a film having a flexible and bendable structure, it can swing against waves. It has been confirmed that the wave force received by the water shielding film 26 is sufficiently smaller than that of the water shielding plate 25.

  The water shielding plate disclosed in the aforementioned Patent Document 1 constitutes a flexible water intake, but the water shielding plate itself is made of an integral rigid body. The conventional rigid structure water-shielding plate described with reference to FIGS. 1 and 2 maintains a stationary state against the wave energy to prevent the propagation of the reached wave. However, the flexible curtain wall water barrier membrane assembly according to the present embodiment does not prevent the propagation of the wave that has reached, but rather transmits the wave energy through a relatively shallow wave energy. The inflow of relatively high temperature seawater in the layer is blocked, and the inflow of relatively low temperature seawater in a relatively deep layer is selectively allowed through the intake 31 formed below the inflow.

  The inventors of the present invention can use a combination of a water shielding plate 25 and a water shielding film 26 as a water shielding member, not as a conventional integral water shielding plate having a rigid structure, as a water shielding member forming a water intake. I found it. Since the shape of the water-impervious film 26 is a structure that flexes flexibly following the wave force, when the wave force is received, it is bent and the wave force is dispersed and absorbed in an arch shape, resulting in the suspension means. The stress applied to the water shielding plate 25 connected via 40 is reduced. As a result, the required strength of the water shielding plate 25 itself and the required strength of the mooring means 32 for mooring the same can be greatly reduced. As a result, the mooring means 32 can be a simple member as compared with the conventional rigid structure water shielding plate or the rigid structure water shielding plate of the flexible structure intake port. Installation work and a robust water-blocking plate are not required, and it is possible to reduce the number of days and costs required for the construction.

  FIG. 9 is a diagram for explaining another embodiment. With reference to FIG. 7, it has been described that the water shielding member includes the water shielding plate 25 and the water shielding film 26. 9, the height hb of the water shielding plate 25 is further reduced and the height hf of the water shielding film 26 is further increased in the water shielding member of FIG. 9. It can also be reversed. The ratio of both responsible for the water shielding function, that is, the ratio of the height hb of the water shielding plate 25 and the height hf of the water shielding film 26 can be arbitrarily determined. In any case, shallow seawater from the ocean 38 is prevented from flowing into the water storage pool 29 over the height of the water shielding plate 25 and the height of the water shielding film 26 (hb + hf). The distance between the lower end 27 of the water shielding film 26 and the sea bottom 28 is adjusted to a desired height h of the water intake 31.

  As shown in FIG. 9, a weight adjusting weight 42 may be provided at the lower end portion of the water shielding film 26-1. In this case, the distance from the lower end of the weight 42 to the sea floor 28 is adjusted to a desired height h.

  A method for installing the above-described hanging curtain wall water-proof membrane assembly 20 will be briefly described. An anchor 9 made of a concrete block, which is attached to the mooring member 32, is installed on a predetermined seabed by a hoist ship. The floating body (water shielding plate alone) 25-1 to which the water shielding film 26-1 is previously attached is towed to a predetermined position, and the anchor 9, the intermediate sinker 34, and the floating body 25-1 are connected by the mooring member 32. To do. After installing the floating body, suspend the impermeable film from the floating body. The floating bodies 25-1 are connected to each other (if necessary, the water shielding film alone 26-1). Finally, it is confirmed whether a water intake port having a predetermined height h is formed.

  Next, the installation state of the suspended curtain wall water-proof membrane assembly 20 will be described. FIG. 10A is a view of the entire coast where the water intake facility using the suspended curtain wall impermeable film assembly 20 is installed as viewed from above, and FIG. It is the II sectional view taken on the line of). 10A, the upper half from the coastline 37 is the sea level 38, and the lower half is the land 39. The arrow indicates the direction in which the waves come. Three revetment works 21, 22, and 23 are performed in a direction substantially perpendicular to the coastline 37, and a suspended curtain wall impermeable film assembly 20 is installed so as to connect the respective tip portions of these revetments. Deep water at a relatively low temperature from the offshore direction of the sea passes through the water intake of the suspended curtain wall impermeable membrane assembly 20 and is stored in a water storage pool (also referred to as “water intake garden”) 29. In the direction of the land of the water storage pool 29, a revetment 24 for the formation of the water storage pool is constructed.

A cooling water inlet 41 is provided in a part of the revetment 24, and the deep water stored in the water storage pool 29 is led to a condenser (not shown) of a thermal power generation or nuclear power plant as cooling water. . Deep water used as cooling water is discharged into the sea area as thermal drainage through a discharge route that is separate from the intake route.
According to the suspended curtain wall water shielding film assembly 20 according to the present embodiment, in addition to the advantages described above, there are the following advantages compared to the conventional water shielding plate.
(1) Since the water shielding plate functions as a floating body, a support member becomes unnecessary.
(2) Since the structure of the water shielding plate alone, the water shielding plate alone and the water shielding film alone, and the water shielding film follow the waves, the reflection of the waves is small, and the influence on the surrounding sea area is reduced. Can be small.
(3) The wave power to the water shielding plate and the water shielding film is greatly reduced, so that the strength of the water shielding plate, the water shielding film, the mooring member, etc. can be reduced, and the initial investment in construction is suppressed. Can do.
(4) Since the steel pipe pile used conventionally can be eliminated to hold the water-impervious member and a simple mooring member can be obtained, the effective width of the intake port is increased. For this reason, when a desired intake area is secured, the required water depth or width is reduced, and the dredging amount at that point can be reduced. Thereby, the influence on the environment of the said sea area can be reduced.

  In addition, the use of this invention is not limited to the cooling water acquisition of a power plant. It should be noted that the present invention can also be used for other uses, for example, intakes for deep water acquisition for beverages, intakes for low-temperature seawater acquisition at seawater power plants using the temperature difference of seawater, and the like.

  As mentioned above, although embodiment of the suspension type curtain wall impermeable film assembly concerning this invention was described, this invention is not limited to embodiment mentioned above. Those skilled in the art can easily make various modifications and improvements within the technical scope of the present invention. The technical scope of the present invention is defined based on the description of the scope of claims.
