In general, rivers in Korea have a rapid increase in flow rate due to heavy rains accompanied by rainy seasons or typhoons, and flow rates are so fast that the reservoirs of rivers are often eroded and lost. As a result, the safety of the levees is threatened, especially the waterside plants of riversides such as reeds and willows are lost, thereby destroying the natural purification function of river water quality and the habitat and ecological environment of fish and algae. The damage and aftermath is very large.

Therefore, in order to cope with such flood damage, conventionally, structures such as concrete retaining walls and stone masonry have been constructed on riversides.

However, in the case of this second embodiment, after the punching of the plurality of vertical pile member 201, the point of installing the horizontal pile member 202 over the vertical pile member 201 is characteristically different, and the vegetation zone mold slopes Another difference is that the composition is formed in two or more steps.

The vegetation zone of FIGS. 2A and 2B is an inclined reservoir reservoir construction method of a stream in which the flow velocity is not fast, and the upper and lower vegetation zone forms are separately constructed as described above.

First, the vertical pile member 201 is subsequently punched out for the configuration of the lower vegetation form, and the horizontal pile member 202 for fixing them is fastened to the upper left and right sides of the vertical pile member 201 by using fasteners. . In addition, the vertical pile member 201a is punched out at a predetermined depth and interval for the configuration of the upper vegetation form, and the fasteners are attached to the upper left and right sides of the vertical pile member 201a by the designed quantity. Use to bind. Then, the stone (natural stone) 204 is filled in the space between the upper and lower botanical beds, while the waterside vegetation (eg, pussy willows) 205 is planted.

In the upper vegetation form, the earth and sand leak prevention member 203 is installed to prevent the outflow of the upper soil, the natural stone 204 is filled, and the willow tree of a predetermined number is planted using the gap between the filled natural stones 204. This construction prevents the loss of soil and provides good habitat and spawning for fish and algae by creating cool shades and hiding places by waterside plants, and greening the riversides, greatly improving the scenery of the riversides. Will be. In addition, the contaminated river water passing through the pores of the filling stone is capable of restoring and preserving the waterside ecological environment, such as the water quality is naturally purified by the filling stone.

3A and 3B show a method for constructing a reservoir shoreline of a rapid stream of rapids, which is a quadrangular form having a predetermined vegetation form (actually, in contact with the slope of the dike, thus becoming a U-shape). The point of forming a unit block type of?) Is characteristically different from the above embodiments in terms of its form.

In order to form the vegetation zone, the vertical pile member 301 of a relatively large diameter is successively punched out, and the horizontal pile member 302 of a circular or semi-circular shape as much as the designed quantity is bolted to a rear surface of the vertical pile member 301. Use a fastener like this to bind. Thereafter, the inner surface of the horizontal pile member 302 is provided with the earth and sand outflow prevention member 303 for preventing the loss of the filled earth and sand, and then fill the inner space of the vegetation zone mold with high quality soil and natural stone. At this time, planting waterside vegetation 305, such as reeds, willow, and the like. At this time, also in order to prevent displacement of the vertical pile member 301 due to the self-weight of the filled soil and natural stone, or to scour the front portion of the vertical pile member 301, as shown, a cube-shaped front surface of the vertical pile member 301 The gabion 306 is provided, and the natural stone 304a is appropriately distributed on the upper surface of the gabion 306. The vegetation zone as described above is appropriately adjusted according to the flow rate and the topography.

As described above, the rectangular unit block type zones, which are installed in contact with the bank slopes, play a role as a handmade product, which significantly reduces the ambient flow rate. It will be deposited and this will create another natural vegetation of aquatic plants such as reeds and ropes. This space has a gentle flow rate, abundant plants, and natural stones, so it provides a good habitat and spawning place for fish and algae. In addition, by reducing the flow rate in the vicinity of the dike in a natural manner, it is possible to increase the safety of the dike and to naturally purify the water quality by the water plants.

4A to 4D show examples of a vegetation zone at the waterway side of a relatively rapid stream of rapids, in which a first stage vertical pile member 401 is punched in consideration of a terrain condition, and the rear top of the vertical pile member 401 is formed. The first stage horizontal pile member 402 is successively installed using fasteners such as bolts to form a first stage wall. In the same way, the two-stage vertical pile member 401a and the two-stage horizontal pile member 402a are bound together using fasteners to form a two-stage wall. At this time, when structural reinforcement is required according to the soil conditions of the site or the slope of the surface, etc., as shown in FIGS. 4B and 4C, the first and second walls are distributed to disperse the stresses of the first and second walls. Install horizontal reinforcement pile member 410 connecting the two walls between the end walls.

At this time, the horizontal reinforcement pile member 410 should not be installed at the inflection point of the linear change, at the inflection point to separate the structure, to cut the horizontal pile member 402 (402a) to change the direction, a separate vertical pile member 401 is installed and connected and constructed by another separate structure. Therefore, the horizontal reinforcement pile member 410 is installed at the center point or a balanced position of the straight section to ensure structural stability.

FIG. 4D illustrates a case in which each individual vegetation zone mold is constructed in several stages in the above-described vegetation zone construction, and a natural stone 404 of a suitable size is disposed in a balanced manner on the front of the first stage wall to prevent scouring. After installing the earth and sand outflow prevention member 403 in order to prevent the outflow of earth and sand, the back of the wall is filled with good quality earth and sand. Then, planting waterside plants 405 such as willow in the soil composition, and if necessary finish with a relatively flat natural stone (404a). This construction prevents the loss of sediment on riversides at high flow rates, and greenens the riversides to create a nature-friendly riverside environment such as walkways, walkways, and rest areas.

5A and 5B show examples of construction of hydrophilic vegetation zones such as gentle slope slope protection and observatory stairs of a river channel, where a relatively large first stage vertical pile member 501 is punched at a predetermined depth and interval, and the vertical pile On the substantially upper back surface of the member 501, a horizontal or semi-circular horizontal pile member 502 is successively installed. In addition, on the rear surface of the horizontal pile member 502 at the intermediate point between the vertical pile members 501, a fixed pile member 520 having a relatively small diameter is punched, and the horizontal pile member 502 is joined to a solid horizontal pile member. Build a erectile food first-tier wall. At this time, when reinforcement of the first-stage wall is required due to the inclination of the slope, soil, etc., the vertical reinforcement pile member 530 is punched at an appropriate interval and depth between the first-stage wall and the second-stage wall at an appropriate interval and from the top. The displacement of the first wall is prevented by external force such as earth pressure.

When the construction of the first-stage wall is completed, the second-stage wall and the third-stage wall are constructed in the same manner, and the earth and sand leakage preventing member 503 is disposed at the rear of the fixed pile member 520 at the rear to prevent the loss of the soil. Install it. Then, filling and compacting with high quality soil and natural stone 504 in the space of the vegetation form, and planting the waterside vegetation 505 in harmony with the surrounding landscape. Here, preferably, the surface of the staircase can be laid with a stone to form a habitat for fish, and by planting grass in a necessary section, it can increase the environmental friendliness.
