Description

[0001] The present invention relates to a method of constructing a block and a construction method,

This embodiment relates to a method of constructing a block and an island.

Adororan refers to a hydraulic structure intended for ecosystem restoration, which is installed for the conservation of various ecosystems including ecosystems and ecosystem conservation, by securing the passage of fishes blocked by transverse structures. Ado is needed for restoration and maintenance of river ecosystem, conservation of ecotourism resources, and activation of fishery through expansion of economically viable fish species, and it is necessary to develop various kinds of fishery such as staircase type, wall type, vertical slot type, artificial underwater type, Varies.

The most common form of ado, the terraced fish, is made up of stairs, in which the water flows along the septum as it goes up the water as it goes down. However, there is a disadvantage in the stepped fish that the sulfur in the fish is uneven and the circulation occurs, and therefore, only the fish having good springiness or swimming ability can be used.

The next most commonly used wedge-shaped waterway is waterway, which is made up of zigzag walls that lead to the flow of water. However, it is difficult to secure a proper water depth because the flow velocity is fast and uneven, and when the water depth in the water is 20 cm or more, the water discharged from the hydraulic structure is large and the water loss is large.

The vertical slot type is designed to be similar to a wall-wing type, but it is designed to reduce the flow of water by bending a portion upstream to form a small bulkhead on the opposite side. However, the vertical slot type fish body is complicated in structure, requires a large construction cost, is difficult to use various fishes, is narrow in width and difficult to use many fishes at the same time, The movement of fish is limited.

Artificial Underwater Eo Doo Island is a natural eo island that allows fishes to swim and move by creating a small stream like a side stream outside the original river. However, there is a disadvantage in that the construction site of the artificial underpass is insufficient and the length is long and the construction cost is large.

The ice harbor type is a type that includes a water flow wall and a non-water flow wall. It has a space where the sulfur inside the island can be picked up, and the fish in which the impending fish can rest. It is a low wall that is immersed in water. It can catch fish through the wall. The wall of umbrella is a U-shaped wall.

However, in order to prevent the conventional ice-harbor type waterproofing block from being lost to the flood season, it is necessary to secure its own weight and to assemble and bind the blocks so that it is difficult to transport and construct the waterproof building. In addition, the distance between the walls of the block is derived from the consideration of the overflow water depth, the step between the overflow walls, and the surface flow rate. If the distance is short, bubbles and turbulence are generated. The length of the block is required to be formed. In addition, in the conventional ice harbor type waterproofing block, circulation flow is generated in the fishery, the fish is disturbed to move to the upstream, and it is difficult to construct the curved or folded ground. If the part of the block is broken and need to be repaired, It is complicated, and the construction cost is excessive. Also, in order to cope with the change in the flow rate of the river, if only the height of the flood wall is adjusted to correspond to the water level, the water of the lower flood block flows to the upper flood block, And there is a problem that the construction cost is excessively applied. In addition, it makes space for planting in the intertidal wall, planting the plant, and the stability of the block is lowered by the growth of stem or root of the plant. Furthermore, in the conventional art, there is no mention of dissolved oxygen in the effluent, and the material of the block and the barrier is also limited to concrete.

FIG. FIG. 8 is a perspective view illustrating a state in which an eudo block according to an exemplary embodiment of the present invention is connected to a reinforced concrete bottom plate 20, and FIG. 9 is a perspective view of an eudo block according to an exemplary embodiment of the present invention. 10 is a perspective view showing a state in which an artificial block according to an embodiment of the present invention is connected to a reinforced concrete bottom plate 20, Fig.

1, an eudo block according to an example of the present invention includes a base block 11, a non-flow block 13 provided at the center upper side of the base block 11, And an overflow block 15 provided in the overflow block 15. Unless otherwise specified, the term "forward" refers to the upstream side, and the term "downstream" refers to the downstream side.

A connecting member 113 to be connected to a reinforced concrete bottom plate 20 to be described later is buried in the foundation block 11 and one side of the plurality of connection members 113 is exposed to the front and rear sides of the foundation block 11. The connecting member 113 is exposed at one side of the groove 111 of the base block 11 and the other side of the connecting member 113 is embedded in the base block 11 and exposed to the front side groove 111. [ And the connecting member 113 exposed to the rear side groove 111 may be embedded in the base block 11 in a separated state but may be embedded in the base block 11 in a state connected to each other. The connecting member 113 may be a screw bar, a bolt, a connecting ring, or the like. The base block 11 is not limited to the shape shown in Fig. 1, the base block 11 is not limited to the same cross section as the cross section of the non-cross flow block 13 and the cross flow block 15, And the pneumatic actuators 155 may extend to the lower end of the base block 11. When the pore 155 extends to the lower end of the foundation block 11, a reinforced concrete bottom plate 20 to be described later is installed including a part of the pore 155. It is also possible to embed a plurality of embedding nuts 115 in place of the connecting members 113 exposed to the grooves 111 and the grooves 111 as shown in the enlarged view of Fig. Or a reinforcing bar formed with a screw may be fastened.

The overflow block 15 is provided at a lower height than the non-overflow block 13 and is formed in a gentle curved shape on the upper side so that the small-sized fish can be easily removed and the overflow block 15 is prevented from being damaged And minimizes the generation of turbulence and bubbles. In addition, a pneumatic hole 155 is provided on the lower side of the overflow block 15, and benthic organisms and the like can be moved through the pneumatic hole 155 and the soil can be discharged.

2) that is lower in height than the overflow block 15 or a gently curved flow guiding protrusion 151 (see FIG. 2) that is lower than the overflow block 15 or a shelf 15 protruding from the overflow block 15, Shaped flow guide portion 151 (see Figs. 3A to 3E).

1, in which the flow inducing protrusion 151 does not exist, when the flow of water flows from the upstream side (front side, right side) to the downstream side (rear side, left side) A considerable number of streams flow downward along the wall surface of the overflow block 15, from the lower side to the downstream side, from the lower side overflow block 15 to the upper side, and to the first overflow block 15 do. It is recommended that the circulatory flow in the fishway is a flow that prevents the fish from recognizing the water flow and moving upstream.

In this case, the water flowing over the upper side of the overflow block 15 is changed in flow direction in the flow inducing protrusion 151 in the horizontal direction, And flows over the overflow block 15 on the downstream side. That is, the flow inducing protrusion 151 can adjust the generation of the circulation flow in the island by changing the kinetic energy of the water flow, thereby allowing the fish to move easily to the upstream of the river. It is preferable that the flow guide portion 151 is located below the water flow, so that the water flows naturally in the horizontal direction after hitting the flow guide portion 151. That is, when the flow inducing protrusion 151 is located at a high level, the flow of water bumping against the flow inducing protrusion 151 drops downward again to generate a circulating flow. When the flow inducing protrusion 151 is positioned low, 151) flow naturally in the horizontal direction and can not flow to the downstream side, and the circulation flow can occur. Therefore, it is preferable that the upper surface of the flow inducing protrusion 151 is positioned between 30% and 70% of its height at the lower end of the overflow block 15. That is, the height of the flow guide portion 151 is preferably set in the above range in consideration of the height of the overflow block 15 itself, the inclination of the island portion, and the amount of oil flow.

In addition, the shelf-shaped flow guide protrusions 151 of Figs. 3A to 3E not only adjust the generation of the circulation flow, but also to smooth out the sulfur. That is, the water running on the flow guiding protrusion 151 flows horizontally and reaches the downstream side downstream side flow block 15, and a large amount of water (mainstream) flows over the downstream side downstream flow block 15, (Downstream) moves downward along the front wall (upstream wall) of the downstream side overflow block 15 and then moves to the upstream side overflow block 15 and then moves upward along the side wall (downstream wall) . The shelf-shaped flow guide portion 151 acts to suppress the flow of the less water, that is, to smooth the sulfur. Like the circulation flow, the small amount of flowing water also interferes with the flow of the water to the upstream of the fish, so that the shelf-type flow guide portion 151 greatly facilitates the movement of the fish.

The shelf-type flow guiding protrusion 151 may be formed as one long shelf type (see FIG. 3A), but a plurality of cut-out portions 152 spaced apart in the left-right direction of the flow guiding protrusion 151 may be formed (See Figs. 3B and 3C), or a through hole 153 may be formed in the flow guiding protrusion 151 (see Figs. 3D and 3E). When the incision 152 or the through hole 153 is formed in the flow guiding protrusion 151, a part of the water flowing over the overflow block 15 slips downward through the incision 152 or the through hole 153 By doing so, the action of pressing the small amount of water downward acts to even out the sulfur in the fish can be made more efficient. The cut-out portion 152 may have a vertical shape (see FIG. 3B) having a constant width on the upper side and a lower side, or a trapezoidal shape (see FIG. In the case where the incision part 152 has a trapezoidal shape with an upward light-tight narrowing, the flowing water flowing in the downstream direction along with the flow of the flowing water is not disturbed, It can flow downward. The through hole 153 is formed in a vertical shape (see FIG. 3D) having a constant width on the upper side and a lower side or in a conical shape (see FIG. 3E) . The cone-shaped through-hole 153 of the upper light-narrowed cone can flow the downward flow only through the through hole 153 without causing excessive turbulence in the flow-inducing protrusion 151, Let's do it.

As shown in FIG. 4, the air block 10 may include an air suction pipe 157 connecting the pneumatic suction block 155 and the upper side of the non-suction block 13. Fish use the dissolved oxygen in the water to breathe. When the amount of dissolved oxygen in the stream is increased, the organic matter is decomposed by aerobic microorganisms and the water quality of the stream is purified. Accordingly, when the air suction pipe 157 is installed in the pore 155, air can be supplied into the pore 155 by the flow velocity inside the pore 155, so that the amount of dissolved oxygen can be increased in the water flowing through the pore 155. The air suction pipe 157 may be connected to the recess 156 by forming a recess 156 having a small cross section in the middle (see FIG. 5), although the cross section of the air suction hole 155 may be constant in the longitudinal direction. , In which case the suction of the air can be further increased. And a venturi tube 158 designed and manufactured according to the Bernoulli principle in the non-flow block 13 and an air suction pipe 157 connected to the venturi pipe 158 from above the non-flow block, By supplying air to the air suction pipe 157 using a DC or AC motor, the speed of the air and the amount of air supplied to the water flowing through the venturi pipe 158 can be adjusted. The venturi pipe 158 may also be installed in the overflow block 15 and may also be connected to an air intake pipe 157 connected to the pneumatic actuator 155 by a DC or AC motor using renewable energy .

As shown in FIG. 6, the pore 155 is a shape loss head changing structure 159 in which rapid expansion and rapid reduction of the cross section are repeated, and the diameter is gradually increased toward the rear as compared with the forward direction. In the normal pore 155, a rapid flow rate occurs, which can make the migration of benthic organisms somewhat difficult. Therefore, it is necessary to facilitate the movement of the benthic organisms if the flow velocity is partially reduced. The shape loss head changing structure 159 in which the rapid expansion and rapid reduction of the cross section is repeatedly performed, And the space of the lumbar region can be utilized, so that the benthic organism can be easily moved. In addition, increasing the diameter on the downstream side of the diameter on the upstream side also allows the flow velocity to decelerate due to the enlargement of the cross section and further restricts the flow velocity to a very small part of the upstream side inlet, thereby making the movement more advantageous.

As shown in FIG. 1, the non-current block 13 may be a U-shaped front opening or a trapezoidal front opening or an elliptical shape. A fish resting space 131 is formed in the opened front, and the fish resting space 131 serves not only as a resting place where the water stagnates and the fishes can rest, but also can serve as a habitat or hide for the fish, .

In addition, the planting space 40 can be formed at the rear of the non-current block 13 as shown in FIG. A gravel layer is provided in the planting space (40), and a soil layer is provided on the upper side of the gravel layer, so that aquatic plants can be activated and grown. Therefore, the habitat of the organism is formed, the space of the habitat is secured, and the river water is naturally cleansed through the vegetation of the aquatic plant, so that the ecosystem is restored efficiently and the river landscape is improved. Also, even if the stem or root of the aquatic plant grows, the effect of the aquatic plant is minimized because the fish block 10 is not affected, so that the fish block 10 is stable. The planting space 40 may be formed on one side or both sides of the sidewall.

The step of disposing and connecting the reinforcing bars 21 between the blocks 10 includes disposing the reinforcing rods 21 between the blocks 10 and connecting the reinforcing rods 21 and the buried And connecting the nut 115 or the connecting member 113 to each other. The connection with the buried nuts 115 may be made by forming a screw in the reinforcing bar 21 or connecting the bolts to the reinforcing bars 21 after the bolts are fastened to the buried nuts 115. Further, the connecting member 113 may be formed with an external thread, and the reinforcing bars 21 and the like, which are formed with screws, may be adjacent to each other, and may be mutually connected by a nut.

The construction of the reinforced concrete bottom plate 20 is to pour concrete on the placed reinforcing bars 21. The width of the reinforced concrete bottom plate 20 is designed considering the width of the island to be installed.

The reinforced concrete bottom plate 20 can be constructed to have a constant height (see FIG. 8) in the left-right direction, or to be constructed so that the height changes from one side to the other in the left-right direction (see FIG. 9). When the reinforced concrete bottom plate 20 is formed so as to have a height gradually changed from one side to the other side in the left-right direction, the side wall 30 is formed at the level difference higher than the height of the non- 30). When the side wall 30 is installed as described above, the function can be maintained even in the wet season.

Bubbles and turbulence are generated in the island when the distance between the blocks 10 arranged between the side walls 30 is short in the direction of the front and rear (upstream and downstream), and the step between the forward and backward flow blocks 15 is long, It is calculated in consideration of the step length between the overflow block 15 and the overflow block 15, and the flow rate.

On the other hand, a step of forming the planting space 40 in the island can be further added. The planting space 40 can be formed on one side or both sides of the outermost side of the constructed island and can also be formed behind the non-side flow block 13, And the vegetation of aquatic plants naturally cleanses the river water when polluted, which is effective for restoration of ecosystem and improves waterfront scenery. In addition, even if the stem or root of an aquatic plant grows, the impact of the aquatic plant vegetation is minimized because it does not affect the eaves block 10, so that the eaves block 10 can provide a stable effect.

As described above, the side wall 30 is first installed in the area where the island is to be installed, the block 10 is disposed, and the connecting member 113 or the buried nut 115 is connected to the reinforcing bar 21, (10) and the reinforced concrete bottom plate (20) are integrated, the structural stability can be ensured and the material cost, transportation cost, and construction cost are reduced, thereby improving the economical efficiency. Also, the block 10 can be easily installed on a curved or folded ground, and even if a part of the block 10 is broken and needs to be repaired, the maintenance is simple and the construction cost is reduced.

It is also preferable that the flow inducing protrusion 151 on the block 10 is located between 30 and 70% of the height of the overflow block 15 at the lower end of the overflow block 15. [ The flow induction projecting portion 151 is for regulating the generation of the circulation flow and uniforming the sulfur flowing in the flowing water passing through the overflow block 15 on the upstream side. When the position is set high, The circulation flow is further generated by falling to the lower side. If the flow rate is too low, it is difficult to properly perform the function of flowing the flowing water striking the flow inducing protrusion 151 naturally downward.

In addition, a manned water path 50 may be further provided at the center, left side, or right side of the island. In order to make it easy for fishes to find the entrance, the size and quantity of fish can be selected in consideration of shape, inclination, and the like. A partition wall may be provided in the induction furnace 50, a venturi pipe may be provided in the partition wall, and an air suction pipe connected to the venturi pipe may be provided.
