Description

[0001] The present invention relates to a zigzag type walking walk and a method of constructing the same,

The present invention relates to a zigzag type walk-on walk, and more particularly to a zigzag walk type walk provided with a puddle somewhere in such a zigzag type road.

Further, the present invention relates to a zigzag type walk-on walk and a construction method thereof, which are combined with a sporadic eco-island for the benthic fish between such pits.

'Bo' is one of the repair facilities for watering rice paddies. It is a place where the river that accumulates the dam is closed and the water is stored. Since this 'bo' is inevitably blocking the flow of water in the spring season, Thereby causing ecological problems. Therefore, although it forms a mild sea lion separately, it is difficult to use fish because it is formally formed next to 'bo' with mostly cement.

In addition, the above-mentioned conventional 'beam' is an artificial concrete structure made of cement, which is not good for a landscape view. Moreover, there is a ultimate problem that it is not possible to secure the water of the wet season, and since the inclination is large, There is a problem that the function of the actual e-mail is almost non-existent.

The existing 'bo', which can not be secured by the above, has the problem of destroying various habitats such as fishes, aquatic insects and amphibians, thereby destroying the ecosystem of the whole river such as algae based on fish etc. .

In order to overcome the above problems, it is necessary to consider the river slope of the stream to secure the island, to construct the shoal and the cattle, and to provide the eco - friendly natural environment The present inventor has proposed Korean Patent No. 839660, "River having a natural-type walk" as a first prior art in order to provide a walk with a fishing boat to a river.

The river having the natural type walk according to the first conventional art includes a foundation compaction part such as a natural stone or a reinforced concrete formed at the lower part of the river; At least one weft portion formed so as to be convexly protruded in the longitudinal direction of the river by using an upper plate of a plasterboard on the foundation compaction portion; At least one trough portion parallel to the gutter portion and formed in the width direction of the river so as to be recessed in the longitudinal direction of the gravel using the upper plate of the gravel portion on the foundation compaction portion; Wherein the gutters form a section of mortar filled with mortar between the gilt slab and the gilt slab so as to overflow the stream water without leaking out and the gut section is concavely formed so as to be able to sink even during the wet season, , A pool is provided upstream of the natural type walking to increase the fresh water capacity of the boats and a riffle is formed around the cow's foot .

1C, a sporadic water channel 76 is provided at the bottom of the natural type walk, and the sporadic water channel 76 is provided with a slag 71, such as a megalithm, at the bottom of the lowest water level, And a mortar 72 is used to fix the crushing water channel 76 to the walkway 70 so that the crane 70 can function as a natural crane. So that the benthic micro-fish is a movable pathway.

According to the first prior art, natural stones, amber stones, etc. are stacked on a conventional concrete beam so that they can overflow naturally. In addition, a pool is provided on the front surface of the concrete, And has the advantage of supplying the flow to the ecological water quality purification biotope of the neighboring rivers. In the ecological characteristics, the riffle and the pool formed in the front part of the natural type walking, , And it can be used as a fish spawning ground, benthic habitat, etc. between pores by accumulating mega stones, natural stones, and amber stones.

Further, according to the multi-function walk with the above-mentioned mountainous fishery, the natural scenery which does not have the characteristic of the structure is formed as compared with the existing concrete beams, and the problem of ecology such as water depth, , But it also has the advantage that it can flow water smoothly in depth, width and so on by using a megalithm of a mountaineering multifunctional fish and can act as a moving path of a fish.

However, the above-described conventional art is not suitable for walking with a large step between upstream and downstream and a short width of the beam.

On the other hand, when the width of the beam is not wide and the step between the upstream and the downstream is large, a certain amount of water can be stored, the fish can rest, and the fish moving along the river can form an island Many prior arts are known in the art for providing a sufficient space for fish to rest, facilitating the passage from the downstream to the upstream and being easy to pass through, and for protecting the aquatic ecosystem.

Particularly, when it is desired to form an island in a river having a large step between upstream and downstream, it is most preferable to form it into a zigzag-shaped island, for example Korea Patent Publication No. 2012-0015557.

The second conventional technique is to provide a water flow that is divided into a slow flow of a fast flow rate and a slow flow of a slow flow rate in one water channel, Provides space for a sufficient number of blocks to be easily passed through from the downstream to the upstream.

That is, in the above-described second conventional art, the wall blocks are provided on both sides of the block, and a plurality of partitions are installed in a zigzag manner in the direction of disturbing the flow of water in the middle of the channels formed by the wall portions, And the end portions of the respective partition walls farther from the wall portion are formed as refracted ends that are refracted toward the upstream direction and the height of the end portions of the partition walls adjacent to the wall portions and the end of the refraction ends is higher than the height of the middle portion of the partition walls .

As described above, in the second prior art, a so-called refraction partition wall is formed by forming the partition walls formed in the midway of the island in a zigzag manner and refracting the end portions of the partition walls toward the upstream side, The flow path formed between the end portion remote from the wall portion and the partition wall is formed with a slow flow, and the flow path formed between the partition wall and the partition wall is formed between the partition wall and the partition wall. It has the advantage that it is very quick and easy for the fish to rest from the downstream to the upstream, as the space formed to serve as a shelter for the fish is formed.

Further, since the vegetation space is formed in front of the partition wall, the flow of water can further be made gradually to the portion, so that the fish can trace back from the downstream side to the upstream side without introducing a large force through the channel in which the slow flow is formed.

Hereinafter, with reference to FIGS. 2A and 2B of the accompanying drawings, a description will be made of a double-sided block according to the second conventional art. A beam 1 for stopping the flow of water to store water is provided. ) Is formed in the middle of the sea.

The block 2 has walls 21 on both sides thereof and the wall 21 is sloped from the top of the beam toward the bottom of the stream downstream of the beam.

Thus, a beam is provided from the upper part to the lower part of the beam, thereby forming an umbrella for fish ascending from upstream to downstream of the river. In the normal case, if the beam is inclined toward the downstream from the upper portion of the beam, the flow of water descending from the beam 1 through the narrower block 2 tends to flow. Therefore, it is not easy for the fish or the like to go up from the downstream to the upstream.

In consideration of this point, in the second conventional technique, the partition wall 22 is provided in a zigzag shape on the wall portion 21 formed on both side surfaces of the block 2. An additional feature of the barrier rib 22 of the second prior art is that the barrier ribs 22 on the farther side from the wall portion 21 are provided with the barrier ribs 22, Is bent toward the upstream direction so that the refractive end 22a is formed. At the same time, the height of the intermediate portion 22b of the partition wall 22 between the end of the partition wall 22 contacting the wall portion 21 and the end of the refraction end 22a is low.

According to the second prior art art block thus formed, the water flow discharged from the beam 1 toward the downstream side is once slowed in its flow velocity by the partition wall. In addition, since the flow of the water is temporarily blocked by the refraction end 22a, and the water flows in a direction opposite to the flow from the upstream, the flow velocity in the gap formed between the refraction end 22a and the wall portion 21 Lt; RTI ID = 0.0 > non-refracted < / RTI >

Therefore, according to the above-described Eudoblock 2, the intermediate portion 22b (see FIG. 2) of the partition wall 22 located at the center of the channel, that is, between the end of the partition 22 contacting the wall portion 21 and the end 22a of the refraction, An overflow and a rapid flow are formed in the intermediate portion 22b and a gap is formed between the refraction end 22a and the wall portion 21 remote from the wall portion Resulting in formation of a slow flow (slow flow).

Therefore, since a subordinate slow flow is formed in the lower part of the block 2, it is very easy and quick for the fish to ascend from the downstream to the upstream.

Meanwhile, a partitioned vegetation space 23 in which aquatic plants are planted to serve as a fish shelter is formed between the partition 22 and the partition wall, and the fish can be rested. Also, the water flow So that the fish can be backed up more quickly and easily.

However, the walk of the second prior art is also a modification of the ice harbor type walk which can not get out of the form of the straight concrete stairs as a whole, and since the surrounding environment is not naturally formed, It is not environmentally friendly because it is made of concrete and it is not used environmentally. It is not only sloping but also sloping because it is made of concrete. Also, since the flow rate is excessively accelerated due to the acceleration, the most fish species go up the river Even if you climb a lonely walk, the scales will peel off or become exhausted, which will adversely affect most fish species. On the contrary, to reduce the slope and to reduce the velocity of the flow velocity, another problem arises that the walk must be very long.

It should be understood, however, that the appended drawings and Examples are provided only to facilitate the disclosure of the present invention, and that the scope of the present invention is not limited by the accompanying drawings and the embodiments, It would be easy to know if you are a person who has.

Best Mode for Carrying Out the Invention Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 3A to 14B.

First, referring to Figs. 3A to 8, the zigzag type walk-up walk of the present invention will be described.

FIG. 3A is a plan view of a river having a staggered walk-up walk according to a preferred embodiment of the present invention, FIG. 3B is a plan view of the staggered walk- Sectional view taken along the AA line. FIG. 5 is an actual construction example of a zigzag type walk-up type walk according to the best embodiment of the present invention, FIG. 6 is a partial detail view of a zigzag type walk type walk according to the optimum embodiment of the present invention, 6 is a cross-sectional view taken along line BB of FIG. 6, and FIG. 8 is a detailed view of a puddle portion of a zigzag-type flood-type walk according to the preferred embodiment of the present invention.

First, as shown in FIG. 3A, the zigzag-type walk-on walk 100 according to the present invention is provided as a walk on one side of a river girder 1000.

In FIG. 3A, a stepped walk is formed at each of the left and right sides of the dive beam 1000. However, since most of the fish do not jump beyond the dive line due to the fact that there is no shelter of the fish that goes up the dive line, 3A. As shown in FIG. 3A, by forming the zigzag-type walk-on walk of the present invention on one side (left side), it is practically possible to perform a substantial degree.

3B, when the slope between the pond 200 upstream of the staggered walk 100 of the present invention and the sedimentation material 300 is urgent, The first barrier ribs 110 and the third barrier ribs 130 protrude from the upstream side to the center in order and the second barrier ribs 120 and the fourth barrier ribs 140 protrude from the upstream side to the center, The second partition wall is staggered between the first partition wall and the third partition wall and the third partition wall is formed between the second partition wall and the fourth partition wall so that the channel of the island is formed into an S shape. In Figure 3B, the center of the channel is denoted by the reference numeral " 190 ". '700' is the embankment on both sides of the stream.

As shown in FIG. 4, the pond 200 on the upstream side of the right side and the downstream side on the left side of FIG. 3B include the puddle 125 (starting from the puddle 105) And 145 and the barrier ribs 110 and 130 are alternately displayed.

On the other hand, although it varies depending on the species, it is preferable that the inclination of the water channel should be 1/20 (5%) or less in order to form a generally smooth island. However, in order to maintain a slope of 1/20 or less, even if the height of a general stream dam (height difference between a pond and a sedimentation tank) is more than 2 m, in the case of a general ice harbor type walk, .

However, in the walk of the present invention, in the case of a normal time, the river water flows in a zigzag flow type so that a slope of less than 1/20 (5% ) Can be significantly reduced. However, since a lot of river water flows in the rainy season such as the shoemaker, as shown in Fig. 4, the river water is overflowed over the partition wall.

4 and FIGS. 5A and 5B, the partition walls are formed in the first abalone (600 * 700 * 850), which is relatively megalithic, so as to increase the dissolved oxygen and slow the flow rate of the flowing water by surface frictional force, (400 * 500 * 600) 102 'of medium size and a medium size second surface (400 * 500 * 600) 102' are fixed by the layer of mortar layer 101 to form a rough surface. It is preferable to fill it with gravel or fillet stones 103, and the bottom surface of the waterway should be treated with a bed rest 102 ".

Furthermore, pools 115, 125, 135, and 145, which are much deeper than the other portions, are formed in the entrance portion 105 and the curved portion (that is, the point where the direction of the island is changed) As the cushion of the tongue is hit, the cushion is made in the puddle so that it can rest in the puddle or provide a temporary habitat there when the fish goes up the 'S' tread.

It should be noted that the puddles 115, 125, 135, and 145 may not necessarily be located at the curve point, but may be located at other locations, but it is preferable that the river water flowing down the S- .

Figures 5 to 8 are actual examples in which a puddle is installed in such a curve.

As described above, it is preferable that the slope of the waterway of the island is not more than 1/20, and the width of the island is set on the basis of the water amount of the spring, but in the case of a river having a height difference of 2 m between the pond and the sedimentation paper, , And the flow velocity of the island is preferably 0.5 to 1.0 m / sec or less, and the water depth is preferably 20 cm or more in the straight channel between the partition walls and 70 cm or more in the puddle of the curve.

As shown in FIG. 6, erosion due to water flow may be large in the vicinity of the puddles 115, 125, and 135, so that the abodes 102, It is preferable to centrally arrange the anti-slip stone 104 which is smaller than the fillet stone 103 but smaller than the lower stone 102 '

5 and 6) and the downstream puddle (135 in Figs. 5 and 6) while forming a puddle on the side of the sweeping zigzag flow type curve 126).

As mentioned above, the central tilt of the moonwalk is less than 1/20 (5%), but it is the case of the 'Mongolian', which is a benthic grade 2 species with weak swimming ability, In the case of the same fish species, the slope of 1/20 (5%) may be too large, so that the inclination of benthic ecosystem passageways between neighboring ponds is preferable. For example, benthic ecological channels and habitats with gradients of about 0.1 to 3% should be created. The benthic fish ecological passageways 126 may be composed of sporadic fish or ecological blocks, but may also be composed of small tubes of diameters D8 to D12 of about 10 cm in length.

6, most of the river water flows along the center line 190 of the waterway along the direction of the broken arrow in FIG. 5, but a part of the entire flow of the water flowing in the direction of the arrows 121, 131 and 141 (About 1/10 of the diameter) of the fish pass through the benthic fish ecological passage 126 directly in the direction of the arrow 121.

On the other hand, the benthic fish ecological passage 126 may be formed of mortar using the gigantic stone 102 and the gravel 103. However, in order to increase the efficiency of the work and to make it uniform, Is more preferable.

Next, with reference to Figs. 9 to 14B, a construction method of the zigzag type walk-up walk of the present invention will be described.

9 to 13 are perspective views showing a construction process of a staggered walk-by type walk according to a preferred embodiment of the present invention. FIG. 9 is a photograph of a walk of a conventional river having a conventional stepwise walk, 11 is a photograph showing a state in which a first-stage partition wall of a zigzag-type walk is formed by piling a stone on a mortar layer, Fig. 12 is a photograph showing a state in which a mortar layer is formed, And Fig. 13 is a photograph of the state in which the partition walls of each stage are covered with the soil. FIG. 14A is a photograph of a completed zigzag-type swim-type walk according to the best embodiment of the present invention viewed from the front portion (upstream side), and FIG. 14B is a photograph of the completed zig- (The downstream side).

First, FIG. 9 shows a conventional method of dismantling a conventional walkway concrete having a stepped walk, and forming a mortar layer 101 on the bottom surface. 10, stones 102, 102 'and 102''are piled on the mortar layer, and stone piling is completed on the mortar layer as shown in FIG. 11 to form a zigzag- (See Fig. 12), and thereafter fill the spaces between the abodes 102, 102 'and the bottoms 102 " The crushing stone 104 is disposed around the puddles 105, 115, 125, and 135 as occasion demands. Finally, as shown in FIG. 13, To plant hydroponic plants. FIG. 14A is a photograph of a completed zigzag-type swim-type walk according to the best embodiment of the present invention viewed from the front portion (upstream side), and FIG. 14B is a photograph of the completed zig- (The downstream side), and the zig-zag type walk-on type walk thus completed is performed.

(Block type according to the present invention Scattering formula  Also,

Hereinafter, an example of implementing the block-type scattering type ADO in block form related to the present invention will be described in detail.

(First example)

Hereinafter, a first example of the block-type scattering type sound card according to the present invention will be described with reference to Figs. 15A to 17 and Fig.

FIGS. 15A, 15B and 15C are perspective views of various fish vegetation blocks for a block-type coasting type fishing boat according to the present invention, FIG. 16 is a perspective view of fish vegetation blocks for a block- And FIG. 17 is a modified example in which a center post is formed by joining fish vegetation blocks for a modification of the block-type coasting type fishing boat according to the present invention to form an island. FIGS. 19 to 21 illustrate a method of constructing an ecological passage inside a bulkhead by combining fish vegetation blocks for a block-type coasting type fishing boat according to the present invention.

First, a fish vegetation block for a block-type coasting type fishing boat according to the present invention is formed by combining two types of blocks. 15A, the main block 20 is, for example, a block body positioned in a one-letter shape in a natural Y shape of a Y-shape, and includes a bottom portion 21 and wall portions 22 The center block 23 may be formed at the center of the U-shaped block body 23 and serves to decelerate the flow velocity of the flow of water, . Further, the central pillar 23 may be formed with a coupling groove 23a when engaged.

The branch block 30 as shown in FIG. 15B is, for example, a block body positioned in a 'V' -shaped tributary in a 'Y' -shaped natural-type block diagram. The branch block 30 includes a bottom portion 31, Shaped block body made up of a plurality of U-shaped blocks 32, each of which is formed of a continuous curved surface having a different curvature than that of the magnetic head, and the direction of the flow of water is set in advance so as to be outwardly directed away from the main block .

Thus, when the main blocks 20 are combined with the branch blocks 30, a Y-shaped block-shaped scattering-type natural-type IDT 11 as shown in FIG. 16 can be formed.

16, the lids may be formed by vertically inverting the assembled bodies formed by joining the main blocks 20 and the branch blocks 30 having the same shape in the upper layer of the sporadic natural shaped louver 11, The block cover 40 as shown in FIG. 15C is separately formed to energize the block bodies of FIGS. 15A and 15B.

At this time, the lid 40 is formed as an asperity in the center of the concrete plate 41 having the same outer shape as the main block or the branch block, so that the lid 40 is formed as close as possible to the natural- And the inner gravel 43 on the opposite side to form friction in the water channel so that the flow rate is adjusted to some extent so that the water flows into the block body or moisture is formed.

Therefore, according to the natural-type fishing line 11 in which the fish vegetation blocks for the block-type coasting type fishing boat according to the present invention are combined, the advantage of being environmentally friendly is that the fish passing and living are not significantly different from the conventional natural type fishing boat However, there is an additional advantage that it is possible to easily implement a natural-type scattering-type fishing line and easy maintenance.

(Modified example)

17 shows a modified example of the first embodiment. The difference between the first embodiment and the first embodiment is that the main block 20 of the first embodiment has a central pillar 23 at the center, Whereas the main block 20 'of this modification does not have such a central pillar 23, and when it is not necessary to reduce the flow velocity because the main air intake port is narrow or does not have a high degree of inclination, Method.

(Example 2)

Hereinafter, a second example of the present invention will be described with reference to Figs. 18A to 18C.

Figs. 18A, 18B and 18C are plan views of various fish vegetation blocks for another example of the block-type coasting type fishing boat according to the present invention.

18A, when the width of the main block 50 is relatively narrow, a gap is formed between the main block 50 in Fig. 18A and the branch block 30 in Fig. 18C, It is preferable to interpose the same connection block 60.

That is, one side of the bottom portion 61 of the connecting block 60 is equal to the width of the bottom portion 51 of the main block 50, and the wall portion 62 of the connecting block 60 is also connected to the wall portion The other side of the bottom portion 61 of the connecting block 60 is equal to the width of the bottom portion 31 of the branch block 30 and the wall portion 62 of the connecting block 60 So that one side is formed to have a small width and the other side is formed to have a wide width so as to extend to the wall portion 32 of the branch block, and furthermore, a separator 63 is formed on both sides of the wide side.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Will be apparent to those of ordinary skill in the art.
