Description

A embankment of a triangle barrier and a carrying out method for river}

The present invention relates to a triangular frame that is constructed in reservoirs around rivers, and in particular, by forming a log frame in the safest triangle shape in the geometric structure and installing it on the slopes of the reservoir, the stability of the lake through the voids formed by plants and stones. The present invention relates to a triangular frame structure for river revetment and its construction method to maximize ecosystem conservation.

In general, with the urbanization of the land, land use has increased and production activity in the river basin has increased, and the river has been a drainage function considering only the two / dimension functions.

In other words, the rivers that were naturally meandering were strengthened or covered, and the lakes were converted into concrete, and due to the decrease in the flow rate caused by the installation of various restaurants and conduits, the rivers lost their self-cleaning ability. Will disappear.

In other words, when the river bank is made of concrete blocks as described above, the growth space of the plant roots is insufficient, and the plant cannot grow due to strong alkalinity, and thus loses the foundation of the celestial vegetation.

In addition, as the vegetation of the celestial vegetation is removed as described above, the plant species itself is reduced, as well as the habitat of fish, algae, aquatic insects, etc. is damaged in sequence. By blocking the penetration of soil layers, the natural streams of vegetation will be regenerated, and the shade provided by the vegetation will disappear, resulting in a change in water temperature, thus functioning as an underwater benthic creature, a habitat for fish, and a spawning site. It will be lost.

Therefore, in order to prevent the devastation of such rivers, a natural river method is constructed in recent years, and the natural river method improves or improves the current artificial rivers into a river having great naturality by introducing an ecological natural method. As a construction method to restore, it is not intended to develop the natural environment mainly for humans but to create an environment where humans and nature coexist, and the maintenance method of the natural river revetment plays the most important ecological role in the stream during the maintenance of the river environment. Ecological regeneration of the coriander and reservoir lakes in charge is to allow the formation of wetlands and aquatic plants on waterfront or on land slopes.

However, there is a difficulty in that it takes a lot of time and money for the natural river construction method as described above, and because the construction method to maintain the river banks in natural form is not yet systematic and economical, it is insufficient to achieve the stability of the lakes, When the water level of the river is increased due to flooding and the flow rate is fast, the structure of the shoreline which has no stability is lost, so that there is a problem not only to protect the natural ecosystem but also to insufficient construction effect.

Therefore, the present invention was devised to solve the above problems, and by forming the log frame in the safest triangle shape in the geometric structure and constructing it on the slope of the reservoir, the stability of the lake and the ecosystem through the space formed by the stone The purpose of the present invention is to provide a triangular frame structure for river revetment and its construction method to maximize conservation.

When the present invention is described by the above drawings, the state of various fasteners used for assembling the frame as well as the state of wood, stone, and plant material designated for constructing a natural water reservoir in a river type is checked. And a triangular frame is formed by using a side (2) that is fixed to the ground with one end and a horizontal splint (2) having a predetermined length, a bolt, a nut and a washer, and the triangular frame and another After connecting three longitudinal splints (3) to each of the vertices so as to connect a triangular frame, and after selecting the construction surface (4) and the trench (5) of the revetment, the triangular frame produced as described above ( 6) is fixed to the construction surface (4) and the trench (5) of the revetment, and is bound using a rubber band or steel wire to firmly secure the joints of each span of the triangular frame (6) during construction, the triangular frame (6) In order to completely fix the inside of the construction surface (4) to check the elevation of the bottom of the trench (5), laying the base rubble (7), and filling the filling rubble (8) inside the triangular frame (6) Maintaining a variety of voids to prevent the occurrence of segregation, in order to prevent the loss of the back of the triangular frame (6) to install the head stone (9) on the triangular frame (6), the triangular frame (6) fixed as described above Perennial aquatic plants or perennial plants are planted for fish habitat, slope protection and shoreline protection at the front of the farm.

Here, the construction method of the triangular frame (6) for river shore revetment is to be installed in the straight portion or the water receptacle in the reservoir to the height of 0.8m or less, and the habitat for the habitat of fish, the portion of which is 0.8m or less And the construction procedure. First, check the log material source, the stone material source and the plant material source, and use the log and the frame production material to make a triangular frame 6 so that one span is 2 m. After manufacturing the foundation trench in the reservoir, and carrying the stone, laying the rubble rubble (7), and in this state to mount the triangular frame (6) and then to fix the triangular frame (6) Rubble filling and slope backfilling are completed. Finally, plants are planted where necessary.

When the triangular frame 6 is constructed in the water reservoir as described above, first, when the triangular frame 6 is manufactured, the hole to which the bolt is inserted is drilled in the correct position of the log in advance, and cracking does not occur around the hole. Check the elevation at the bottom of the trench (5) and lay down the rubble (7), but do not let the sharp part of the rubble protrude on the surface, and in the case of the triangular frame (6) installed in the reservoir, if necessary Unevenness can be taken into account for each span, in which case the end-to-end bundling must be thoroughly carried out.

On the other hand, in the case of the triangular frame (6) structure that is constructed in the reservoir of the river, as shown in Figures 2 and 3, the attention (1) and the transverse splint in the upper portion of the trench (5) formed at the lower end of the rake slope A triangular frame (6) consisting of (2) and a longitudinal splint (3) is installed, the triangular frame (6) is transversely having two lengths (1) and a predetermined length, one end of which is fixed to the ground. The horizontal splints (2) are installed in a triangular frame by assembling each other through bolts, nuts and washers, and three longitudinal splints (3) are fixed at each vertex to connect the frame and another frame. A triangular frame (6) is made, the rubbing rubble (7) is filled inside the trench (5) so that the triangular frame (6) is fixed to the construction surface (4) and the trench (5) in the lake, Filled rubble (8) is filled inside the triangular frame (6) and triangular frame (6) The head 9 is installed on the back of the structure.

That is, the structure of the triangular frame (6) constructed in the reservoir is used a variety of materials, the construction materials will be described as follows.

Wood for the triangular frame 6; Attention (1) and cross-section (2) are the latest preserved primitive trees defined by the Forestry Research Institute, and the preservation treatment is a preservation state in a manner that does not adversely affect living organisms, and the attention (1) is one side thereof. The seedlings are carried out at the ends and the horizontal splints 2 do not carry out the pruning, and the attention 1 and the horizontal splints 2 mean larch having a predetermined diameter. 1) and lateral splint (2) means lumber that has not been planted with preservatively squeezed columnar (Larch).

Fasteners; Bolts, nuts, and washers for log fixing are plated KS products that use appropriate specifications.

Filled rubble (8); The rubble filled in the triangular frame (6) is a broken rubble or natural stone (locally available stone) using a minimum dimension of one side 200mm, the maximum dimension of one side 400mm or less, and the filling rubble (8) is a triangular frame (6) The triangular frame (6) is to be filled in such a way that it is fixed by rubble, and the front shape is to be filled firmly so as not to escape from the prefabricated filling, but the voids between the rubble are to be maintained.

Base rubble 7; As a rubble laying on the front of the triangular frame (6) as a rubble to prevent floor loss and triangular frame (6) loss due to scour at the time of flooding, to prevent slope loss and to support the habitat of fish that prefer stones After the rammer compaction or manpower compaction, the rubbing rubbish (7) is partially lost due to water flow during construction. If there is no structural problem in the triangular frame (6) by the supervisor's judgment, the damaged part is recognized and maintained. In addition, the scale of the rubble rubble 7 is determined to be hydraulically safe.

Head stone 9; This headstone 9 is made of broken rubble, processed stone and natural stone (locally available stone) and the size is determined to be hydraulically safe.

And, in order to prevent the loss of the rear of the triangular frame (6), the head stone (9) installed on the upper triangular frame (6) should be a solid construction so as not to leave the stone, the top portion of the backfill rubble (10) is also topsoil Thoroughly squeeze together with the sand to prepare for spills, and the front of the triangular frame (6) can be planted perennial aquatic plants necessary for fish breeding, such as babies, irises, irises, herbaceous, pussy willows, Perennial plants can be introduced for slope protection, shading, and future shore maintenance.

Therefore, the transition process of the triangular frame (6) for river revetment constructed as described above is shown in Figure 5, when manufacturing the porous space through the triangular frame (6) and the log of the triangular frame (6) And stone play a role as a revetment, plant growth, stabilization of the revetment slope, microbial habitat begins at the first transition, the integration of logs, stones, willow roots, plant mobilization, logs at the second transition Corrosion (microbial habitat), new voids on stable slope floors (fish habitat, spawning, hideouts), water purification, and willows and stones act as reinforcements, so that these transitioned lakes include planarias, crayfish, lobsters, lobsters, tortoises, It is possible to inhabit a living creature such as a fly, a robber, or a creek.

On the other hand, the water reservoirs constructed as described above are important for their maintenance after construction. First, in addition to excessive buckling and overturning of the log triangular frame (6) due to fluctuations in the riverbed and conditions in the downstream of the construction. Even if there is a loss or deposition of the bed, the monitoring results do not need to be supplemented if there are no major problems in the dimensional safety, and it is advantageous to maintain various ecological environments.

In addition, the plant introduction portion such as the willows should be appropriately cut (once every 2 to 3 years) after the sourcing in the case of the part to help the rooting with proper watering and prevent the overgrowth of the willows. Continuous observation of wood cracking and erosion should be monitored as necessary for the biological and hydraulic function of the wood erosion, and some delamination should be maintained to favor aquatic life.

Therefore, by constructing the triangular frame (6) structure in the reservoir of the river as described above, the voids are enlarged by the wood and stone, which is advantageous for the aquatic life and reptiles, the willows and the like to form the shade and bushes, water surface and plants Algae habitats favor shade and bushes in the shade spaces between them, and cracks and erosions of log cracks that occur in the triangular frame (6) are inhabited by organisms such as lobster or crustaceans, marshes and soy clams. Being a food for fish and algae is beneficial to the food chain formation.

As described above, according to the triangular frame structure for river banks and the construction method according to the present invention, by constructing a triangular frame in the reservoir of the river to form a natural type of lakes, it is possible to maximize the stability and ecosystem conservation of the lakes, By lubricating and growing various plant materials on the low water surface of the lake, it can visually freshen and decorate the lake naturally and make the natural landscape excellent.At the same time, the logs of the triangular frame are corroded to increase the root uptake of the willows. The stones and plants are entangled with each other to economically create a natural and permanent natural revetment, and the barrier and the stones and plants are shaded to reduce the atmospheric superheat.
