Description

  The present invention relates to a suspended curtain wall water shielding plate assembly, and more specifically, to a suspended curtain wall water shielding plate 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. Can reduce the effects of airborne 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 water intake of the conventional gravity type structure was comprised by the rigid structure which receives and supports the wave force which acts on a water-impervious board with a pile.

  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 version), 5 is a steel pipe pile, and 6 is bottom slab 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 shielding board 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.

  Accordingly, it has been proposed that the structure of the intake port be a flexible curtain wall water shielding plate that allows the water transmission plate to oscillate together with the wave that reaches and allows the propagation 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 this application document, it is used for the pre-fabricated water shielding plate of the specification water intake.

  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.

  Here, the “water intake for cooling water” disclosed in the aforementioned Japanese Patent Application Laid-Open No. 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 port, 7 is a water shielding plate (PC version), 8 is a pivotal support, 9 is an anchor (box culvert), 10 is an opening for deep water intake, 11 is a pivotal support, and 12 is a floating body. , 13.

  Embodiments of a suspended curtain wall water shielding plate assembly according to the present invention will be described below in detail with reference to the accompanying drawings.

  First, a general outline is provided so that an image of the suspended curtain wall water shielding plate assembly 20 can be easily grasped.

  5 is a plan view of the suspended curtain wall water shielding plate assembly 20 as viewed from above, FIG. 6 is a front view, FIG. 7 is a cross-sectional view as viewed from the II direction of FIG. 5, and FIG. It is an expansion perspective view for demonstrating. The suspended curtain wall water shielding plate 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 sea, and the lower side is the land direction. The direction of the arrow is the direction in which the waves are pushing. Two rows of revetments 21, 22 are made generally parallel to the direction of waves, and a suspended curtain wall water shielding plate assembly 20 is installed between these revetments 21, 22.

  The suspended curtain wall water shielding plate assembly 20 forms a water intake for selectively taking deep water by positioning the water shielding plate at a desired height from the seabed. Therefore, it is necessary to position the water shielding plate at a desired height by an appropriate support member.

  As shown in FIG. 8, the support member 27 that suspends the water shielding plate 25 includes, for example, a plurality of leg portions 28 and 29, two leg portion connecting members 30 and 31 that connect the leg portions to each other, It consists of a water shielding plate holding member 32 that suspends (that is, suspends) the water shielding plate 25 between the part connecting members. At the same time, it is easy to understand with reference to FIG. 5. As shown in FIG. 5, the plurality of leg portions 28 and 29 are fixed to the seabed in almost two rows in the sea direction and the land direction. In order to approach the leg portion 28, the land-side leg portion 28 is fixed obliquely so as to approach the sea-side leg portion 29. Similarly, the plurality of leg portions 28 in the land direction are connected to each other by the leg connecting members 30. Similarly, the tip portions of the plurality of leg portions 29 in the sea direction are connected to each other by the leg connecting members 31.

  A water shielding plate holding member 32 is provided to suspend the water shielding plate 25 between the two leg connecting members. A plurality of water shielding plates 25 are suspended from the water shielding plate holding member 32 by appropriate engaging members 34.

  By determining the distance between the lower end of the water shielding plate and the sea bottom in advance and calculating the dimensions of the support member 27, the water shielding plate, etc., the distance from the sea direction between the lower end of the water shielding plate 25 and the sea bottom is determined. It is possible to form a water intake that blocks shallow water at relatively high temperatures and selectively draws only relatively deep water at a relatively low temperature.

  As shown in FIG. 7, the water shielding plate 25 receives a wave and swings around the engaging member 34.

  A detailed description will be given 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 the shore (shore edge). A suspended curtain wall water shielding plate assembly 20 is installed between these revetments 21 and 22 in a generally vertical direction with respect to a direction in which waves are pushed. In addition, since the water shielding board assembly 20 is very long, for example, several hundred meters, a part thereof is omitted in the drawing.

  The plurality of leg portions 28 in the land direction are connected to each other by leg connecting members 30 at the respective leading ends. Similarly, a plurality of leg portions 29 fixed in a line in the sea direction are also connected by a leg connecting member 31 at each tip. Opposing leg tip portions are typically covered and fixed with a head cover 33 formed of concrete.

  See FIG. In the figure, reference numeral 35 denotes the current sea level, H.W.L. (High Water Level) is a high tide level, and L.W.L. (Low Water Level) is a low tide level. As shown in FIG. 6, the water shielding plate assembly including the plurality of water shielding plates 25 is suspended from the support member 27 so that the upper end portion of the water shielding plate assembly always appears slightly from the sea surface.

  The essential function of the suspended curtain wall water shield plate assembly 20 is to secure the water intake depth, that is, to position the water shield plate 25 at a desired height h from the sea floor 24 and to adjust the height of the water intake 26 (block from the sea floor 24). By determining the length to the lower end of the water plate, the seawater in the shallower layer is dammed and only the desired relatively low-temperature deep water is taken. Therefore, the water shielding plate 25 is positioned at a desired height h by an appropriate support member 27.

  By appropriately positioning the water shielding plate 25, a water shielding port (opening) 26 is formed between the lower end portion of the water shielding plate 25 and the sea floor 24, and the relatively low-temperature seawater in the deep layer can be selectively taken in. . In the water shielding plate assembly composed of a plurality of water shielding plates 25, a plurality of water shielding plates are arranged in a row so as to block the inflow of relatively hot seawater in a shallow layer.

  As shown in FIG. 7, each water shielding plate 25 suspended from the water shielding plate holding member 32 of the support member 27 using the engaging member 34 swings around the engaging member 34 with respect to the waves. be able to. The conventional rigid structure water shielding plate described with reference to FIGS. 1 and 2 maintains the immobile state against the wave energy to prevent the propagation of the reached wave. However, the flexible water shielding plate 25 according to the present embodiment does not prevent the propagation of the wave that has reached, but allows the wave energy to pass through and propagates the relatively shallow seawater in a relatively shallow layer. It shuts off and selectively allows inflow of relatively deep seawater at relatively low temperatures.

  The inventors of the present invention have an important design condition of the suspended curtain wall water shielding plate assembly 20 as a horizontal acting force of the engaging portion (also referred to as “joining portion” or “joining portion”, for example, a hinge portion). It is determined that f and the deflection angle α of the water shielding plate 25 are present. The horizontal acting force f of the hinge part 34 determines the strength of the leg parts 28 and 29, that is, determines the diameter of each leg part, the interval between adjacent leg parts, the driving depth of the leg parts 28 and 29 with respect to the seabed 24, and the like. This is essential data.

  As a result of conducting a two-dimensional water hydraulic experiment under the wave condition at this model point, using one of the candidates for constructing the suspended curtain wall water shielding plate assembly as a model point, the horizontal acting force f of the hinge part 34 is It has been found that the wave reflectivity and wave period are greatly affected by the revetment (reference numeral 42 in FIG. 9) that collides with the wave direction when the wave reaches the coast. In addition, the vertical length H of the water shielding plate alone is determined by the depth of the ocean and the height h of the intake port, but it has been found that the thickness of the water shielding plate is relatively less affected by wave power. Furthermore, it was found that the influence of wave force is less when the weight of the water shielding plate is relatively heavy.

  In any case, the suspended curtain wall water shielding plate assembly according to the present embodiment can be significantly reduced to 1/9 to 1/4 of the wave force compared to the conventional rigid water shielding plate. confirmed. That is, it was confirmed that when the water shielding plate 25 swings so as to transmit wave energy, the influence of wave force on the water shielding plate 25 is reduced by 3/4 to 8/9. As a result, the supporting member 27 can be a simple member as compared with the conventional rigid structure water shielding plate, and the large-scale and robust pile driving required for the construction of the conventional rigid structure water shielding plate. Construction work and robust water shielding plates are not required, and it is possible to reduce the number of days and costs required for the construction.

  Further, the deflection angle α of the water shielding plate 25 is essential data for determining the installation angle of the leg portions 28 and 29. As a result of the experiment, it was confirmed that the maximum deflection angle of the water shielding plate 25 is greatly influenced by the revetment reflectivity and the wave period. However, in any case, it has been found that the maximum deflection angle of the water shielding plate 25 does not exceed about 25 degrees. The maximum deflection angle of the water shielding plate 25 was determined, the installation angles of the leg portions 28 and 29 were determined correspondingly, and the strength of the leg portions 28 and 29 was confirmed.

  8 and 5, the support member 27 includes a plurality of leg portions 28 and 29, leg portion connecting members 30 and 31, and a water shielding plate holding member 32. Specifically, the leg portions 28 and 29 are made of, for example, steel pipe piles, each steel pipe pile 29 in the sea direction is inclined to the land direction, and each steel pipe pile 28 in the land direction is a slant pile inclined to the sea direction. Yes. The leg connecting members 30 and 31 and the water shielding plate holding member 32 are made of, for example, a steel pipe. These support members 27 are preferably subjected to heavy anticorrosion treatment so as not to corrode against the salt content of seawater.

  The leg portions 28 and 29 made of steel pipe piles are preferably fixed to the seabed 24 by a pile foundation (not shown) wound with concrete.

The water shielding plate 25 is preferably suspended (i.e., suspended) by an engaging member 34 having a hinge structure with respect to the water shielding plate holding member 32. As the engaging member 34, any engaging member 34 can be used as long as the water shielding plate 25 is suspended and the water shielding plate 25 can swing following the wave. It is preferable that the engaging member 34 is removable and the damaged water shielding plate 25 can be replaced at any time.

  In general, adjacent water shielding plates 25 are suspended independently of each other.

  However, if the temperature of the taken-in seawater rises from the design value due to water leakage from the gap between adjacent water shielding plates 25, the adjacent water shielding plates 25 are connected to each other by a connecting member (not shown). It can also be linked. The connecting member may be a member that suppresses the relative movement of the adjacent water shielding plate 25 such as a wire, a chain, or the like, or the adjacent water shielding plate 25 such as a fan-shaped waterproof film. It may be a member that allows relative movement (flexible water-impervious connecting member). Any member can be employed as long as it can substantially function to seal water leakage from between the water shielding plates 25.

  Furthermore, it is preferable that the water shielding board 25 is removable from such a connection member. Since the hinge structure 34 and the connecting member are removable, the damaged water shielding plate 25 can be replaced alone. Since the water shielding plate itself can be replaced, the water intake h can be changed by preparing water shielding plates of various lengths H in advance.

  Please refer to FIG. The water shielding plate 25 is typically formed of reinforced concrete. Further, the influence of the wave force on the engaging member 34 can be reduced by using the water shielding plate 25 as a floating body.

  However, according to the strength required for the water shielding plate 25, the water shielding plate 25 can be formed, for example, by forming the outer wall from ordinary concrete and incorporating an H-shaped rope as a partition wall.

Further, the water shielding plate 25 has a buffer material 36 in the peripheral portion, and can also prevent contact destruction between the water shielding plates. In this case, as a structure of the buffer material 36, for example, a structure in which polyurethane is coated on the surface of the main material concrete can be used.
Further, the water shielding plate 25 can also be adjusted in weight by filling the internal space with polystyrene foam or the like. The reason for adjusting the weight is to prevent an increase in weight due to water leakage. Further, depending on the weight of the water shielding plate 25, a resonance phenomenon occurs due to the wave period, and the suspended curtain wall water shielding plate assembly 20 is damaged, so that the resonance phenomenon does not occur. Since the water shielding plate itself can be replaced, it is possible to change to a water shielding plate having a weight that does not cause a resonance phenomenon with respect to the wave period by preparing a water shielding plate of various weights in advance.

  FIG. 9A is a view of the entire coast where the suspended curtain wall water shielding plate assembly 20 is viewed from above, and FIG. 9B is a cross-sectional view taken along line II of FIG. 9A. It is line sectional drawing. 9A, the upper half from the coastline 37 is the sea surface 38, and the lower half is the land 39. The arrow indicates the direction in which the waves come. Three revetments 21, 22, and 23 are made in a direction substantially perpendicular to the coastline 37, and a suspended curtain wall water shielding plate assembly 20 is installed so as to connect the respective tip portions of these revetments. Relatively low-temperature deep water from the offshore direction of the ocean passes through the intake of the suspended curtain wall water shielding plate assembly 20 and enters a water storage pool (also referred to as “condensate water storage tank” or “cooling water storage tank”) 40. Stored in In the direction of the land of the water storage pool 40, a revetment 42 for the construction of the water storage pool is constructed.

  A cooling water inlet 41 is provided in a part of these revetments 42, and the deep water stored in the water storage pool 40 is used as cooling water and led to a condenser (not shown) of a thermal power plant or a nuclear power plant. ing. Deep water used as cooling water is discharged into the sea area as warm wastewater through a different discharge route from the intake water.

The construction and maintenance of the suspended curtain wall water shielding plate assembly will be described. During construction,
The steel pipe piles 28 and 29 are driven into the seabed 24 by using a Pibro hammer in combination with the water jet. After placing the steel pipe pile, the heads are connected by steel pipes 30 and 31. The steel pipe, the engaging member 34, and the water shielding board 25 which are the water shielding board holding members 32 are assembled beforehand, and this is installed in a pile head with a hoist ship. Thereafter, the pile head is fixed with concrete 33. In addition, the adjacent water shielding board 25 is connected with a connection member (not shown) as needed.

  At the time of maintenance after construction, the engaging member (hinge structure) 34 and the water shielding plate 25 can be exchanged, respectively. Therefore, the damaged engaging member 34 and the water shielding plate 25 after a predetermined period of time are individually replaced. Is done.

In addition to the advantages described above, the suspended curtain wall water shielding plate assembly according to this embodiment has the following advantages over the conventional water shielding plates.
(1) Since the wave force on the water shielding plate is greatly reduced, the number of piles used as legs can be reduced, and the initial investment in construction of the water shielding plate assembly can be suppressed.
(2) Since the water shielding plate swings following the wave, the reflection of the wave by the water shielding plate is small and the influence on the surrounding sea area can be reduced.
(3) Since the number of piles used as legs can be reduced, the effective width of the water intake 26 below the water shielding plate increases. For this reason, when a desired intake area is secured, the required water depth becomes shallow, and the dredging amount at that point can be reduced. Thereby, the influence on the environment of the said sea area can be reduced.

  As mentioned above, although embodiment of the suspension type curtain wall water shielding board assembly which concerns on this invention was described, this invention is not limited to embodiment mentioned above. The application of the present invention is not limited to obtaining cooling water for power plants. It 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. Those skilled in the art can easily make various modifications and improvements, all of which are included in the present invention. The technical scope of the present invention is defined based on the description of the scope of claims.
