Abstract

The present invention relates to a flow structure of streams in contact with flowing water and land such as rivers, lakes, shores, and rivers.

Various riverside rivers form natural environment while forming various natural ecological environments according to the winter season, the flow of flowing water, and the surrounding environment. It is said that the human body is composed of artificial concrete or stone as it is convenient for humans to achieve the effect of aesthetics and dimensions at the time of installation. It has caused tremendous harm and ultimately brought about a serious crisis on human life itself. In order to solve this problem, various methods have been proposed, and among them, a method of forming a natural vegetation zone along the stream has been suggested as a representative solution.

In the present invention, the vegetation roll constituted by weaving coconut fiber yarns is eroded due to the high flow velocity, and is disposed in the water changing unit together with a gabion having a strong resistance. Therefore, to prevent the erosion due to the high flow rate to help the proper vegetation growth and enjoy the effect of ecosystem restoration in a short time.

Description

Shore line structure capable of natural habitants for various lives}

The present invention relates to the provision of a natural vegetation-type flow stream structure for flow streams such as lakes, rivers, shores, reservoirs, and urban streams. Particularly, the stream streams are separated by a top section, a slope section, a foundation section and a water change section. The present invention relates to the provision of flow-and-river structure that allows the optimal restoration of the natural ecosystem in the shortest time by selecting and installing materials and structures suitable for the site.

In general, the slopes of natural mountains or rivers are artificially damaged and deformed in rivers and reservoir constructions around the city, so that the slopes are covered with various revetment members mainly on concrete to protect the levees. At the base of the lower surface of the base, there are ways to protect the foundation by installing a gabion filled with stones in a polygonal concrete foundation or wire mesh.

Rocks and concrete structures such as rivers, lakes, and shores were initially recognized as very well-organized forms, and are recognized as a triumph of modern civilization. However, there is a problem that re-installation is indispensable after a certain period of time due to the collapse of the infrastructure itself while the artificial structure does not form a close contact with the surrounding plants and keeps separated state. Another problem is that various fish, algae, and various plants that flourish the streams in their habitats are extinct because they cannot find their habitat by artificial structures. More seriously, their extinction has caused tremendous damage by falling into dead rivers or lakes, where natural pollutants, fresh air, and urban dwellings have lost their functions.

The recent global trend is to eliminate artificial structures and create the most natural-friendly rivers and reservoirs.Therefore, the use of concrete structures in the construction of flowing rivers or riversides where constant waves occur. It is suppressed and installs a natural structure by stacking several branches and ends with gabions or embalmed wooden bars wrapped with a wire mesh in a certain form using a mesh wire mesh. However, the mesh chain wire is oxidized and corroded indefinitely after a certain period of time, and thus loses its support for stone or gravel. Therefore, as the substructure collapses, it causes the overall collapse of the slope, so it must be rebuilt after a certain period of time. As the structure is destroyed by the vegetation zone, the vegetation zone soaks and collapses and disappears before the strong bearing force caused by the roots.

Another disadvantage is that the corroded wire mesh acts as another environmental hazard, and there is almost no formation of vegetation zones, which is a big obstacle to the growth of fish and shellfish. In addition, the waste of invalid budget generated by such a repetition of construction cannot be ignored.

In addition, the slope is installed as a revetment structure of concrete member and the vegetation zone such as pussy willow or grass is forced to be in contact with water, but considering the fact that the base surface is various soil structures such as sand, sand, rock, etc. Application is only partial success. In other words, there is a high probability of failure and the formation of vegetation zones when the same structure is installed in other streams with the same precedence that one structure is good without comprehensive consideration of each part of the top, the slope, the foundation and the water change system. It is also weak and, in severe cases, it can only act as an accelerator to further disrupt the natural ecosystem of Korea due to the incorporation of foreign plants.

In order to solve the above shortcomings, the present inventors have developed a bio-breathable ophthalmic member in Patent No. 125694, and developed a natural type ophthalmic construction method using this ophthalmic member. By the way, the provided raft members have been able to install natural vegetation of natural vegetation better than existing rafts composed of rocks or concrete materials, but they have various targets for varying phenomena such as various flow rates, soil structures and vegetation zones. There are many disadvantages in the formation of the flowing water stream structure. That's the river. Since the natural environment such as sewage, beaches, swamps, etc. changes only on the side of the river, the introduction of uniform and uniform methods should be supplemented to achieve the purpose of preventing the purpose of erosion, creating a short-term natural vegetation zone, and forming the desired ecological environment. Many assignments have been pointed out.

In particular, even in the same streams flowing in direct current or grain, it distinguishes water-prone areas with relatively high erosion and relatively stable non-water-probe areas, and installation structures for places where there are continuous blue erosion such as appeals and coasts. The boundary does not provide an installation structure for the proper installation method according to various soil structure changes such as sand, mud, sand and sand. In addition, only the structures installed in response to severe changes in flow rate as well as in the case of severe changes in the riverbed during winter, summer and heavy rains can expect stable prosperity of planted vegetation. In addition, there was a lack of provision of the stream water structure to restore the natural ecosystem in the shortest time by using a combination of structures such as existing rock materials and structures suitable for attracting plant life while preventing the outflow of soil.

The most common method of river maintenance is to cover the stone with a wire mesh wire to form a mesh and place it in direct contact with running water to prevent erosion by water. The biggest drawback of this approach, however, is that the plant cannot grow at all. This shortcoming leads to the destruction of the habitat of fish and shellfish, followed by the destruction of ecosystems.

In order to solve the above disadvantages, the present invention divides the flowing water stream into the top end, the inclined part, the base part, and the water change meter, so that the flow rate of the flowing water is strong, not merely by stacking stones, but by erosion prevention. It is related to the structure of the river flow that allows to be placed together.

In particular, the present invention has a myriad of fine pores other than stones and rubble, such as rubble or sandstone, which have a simple erosion resistance against water-changing watersides, and flows until the vegetation is planted to form a stable structure. It shows the stable resistance to the roots of the plant, and the roots of the plant completes a stable structure, and the rolls, nets, felts, and jute bags that decompose and decompose naturally are used appropriately for the installation environment. Even in such an artificial structure, it is intended to provide a stream structure that allows the restoration of the natural ecosystem in the shortest period of time by providing the habitat for fish and shellfish as well as the purification of various pollutants of the riverside based on these material characteristics in the shortest period.

The present invention divides the flow stream into the top, the slope, the foundation, and the water change account (the boundary between the land and water where the flow is always in contact or partially flooded) and the river, and then the most natural In addition to being friendly, natural vegetation zones are formed after a certain period of time to prevent erosion or scour caused by running water with natural vegetation structure. In particular, it is the best to make natural vegetation in the shortest time by appropriately matching durable materials such as sandstone, rock, and concrete member with permanent corrosion resistance and natural materials that create stable ecosystem environment while showing temporary corrosion resistance required for plant proximity. It relates to the provision of a cheonyeon structure.

In the present invention, the configuration of the flow stream is divided into three cases of relatively weak flow rate (specifically less than about 2㎧), medium flow rate (about 2 to 3㎧) and strong flow rate (3㎧ or more). , Even at the same flow rate, it is divided into a worm part and a non-water worm part to which water erosion is directly applied, so that the material and the composition used in each case are different. Here, the strong flow rate refers to the case of severe flow rate due to rapid flooding of mountain valleys or rapid flooding, and the weak flow rate refers to quietly flowing rivers, lakes, and coastal areas. In addition, the nymph is called the outer shell of the celestial body when it flows while forming grains even in the same flowing water, and the erosion is performed by applying the rotational force and force of the water by rotation. And the opposite side is rather the place where sediments moved by flow velocity are deposited. As a result, the design of the structure should be made to prevent the outflow of the soil even at the same flow rate. In the case of the region where the water level fluctuates severely during the flood, special measures for the bottom edge of the riverbed are necessary.

In particular, the present invention prevents severe erosion and structural destruction at the same time as a rock-like material having permanent durability to the water change system, and is a structure composed of natural materials having temporary durability, and is porous and maintains a stable structure until the vegetation zone is swelling. It acts as a stable vegetation habitat in the early stage, and after a certain period of time, it is intended to form the desired structure by using porous porous materials having limited spontaneous corrosiveness to help propagate the natural vegetation that grows naturally. will be.

The present invention is a natural material of the above material is to stabilize the vegetation zone and at the same time slowly and naturally corroded to function as a habitat and nutritional resources of various microorganisms, the remaining rock members, concrete members to operate as a basic skeleton structure for the fragile structure of the river water stream It is possible to provide a natural vegetation in a short period of time with a good balance between the and humus.

Therefore, the present invention allows a variety of vegetation plants to be planted while using nets, felts or roll members of natural materials on slopes inclined toward riverbeds and lakes, and has a limited durability against water erosion systems corresponding to constant water level. The roll member configured to exhibit resistance is composed of various layered structures, and the base part corresponding to the water, such as riverbeds and lakes, is treated with materials having permanent corrosion resistance such as rocks and concrete members. In addition, according to the environment to be treated on the top end portion to form an extension structure of the material installed in the inclined portion and to provide a structure reinforced with durability as needed rock.
