The eco-friendly dam having the lower water purifying functionality and eco-type holes}

The present invention relates to an eco-friendly vegetation dam with a drain pipe and an ecological framework, an ecological passageway and an ecological hole capable of smoothly discharging lower water to the dam body, and more specifically, a 'Λ' shape inside the dam body. Form a drain pipe having a bent portion, install a water level control pipe horizontally from the upper surface of the bent portion of the drain pipe to adjust the water level of fresh water, and the drain hole of the drain pipe is installed lower than the bent portion to facilitate discharge and at the same time Increasing the suction power, and the inlet of the drain pipe is installed close to the reservoir bottom to smoothly inflow and discharge the sediment of the lower layer and the dam bottom to improve the water quality, to form an ecological framework on the dam shoulders and to always flow water on the dam body By connecting the ecological passage and the ecological hall, water can flow into the dam body and the shoulder of the dam at all times and flow. It relates to environmentally friendly vegetated check dam to be blessed.

In general, the four-sided dam refers to a dam that is constructed to prevent the flow of sediment and to prevent the flow of sediment as the rapids dug the riverbed and cuts the foot of both mountains in the valley with a large river gradient. The four-sided dams installed to prevent flooding in mountain valleys can be classified into two types, one being a gravity dam and the other being a buttress dam.

Gravity dams generally function to prevent damages downstream from dams by confining water and soil flowing from upstream, and are constructed of concrete structures with watertight passages and drainage holes to allow a certain amount of water to flow according to the fresh water level. Say that.

However, such a gravity dam discharges water according to the level of fresh water. At this time, the discharged water is only the upper water of the fresh water, and the lower water, which cannot be discharged from the lower part of the fresh water, is decayed after a long time. As it causes pollution and discharges only upper water, suspended matter and foreign substances settle on the floor for a long time, and the entire fresh water is contaminated due to not being discharged, which causes deterioration of water quality or clogging of drainage holes by sediment and suspended matter which precipitate. As a result, problems such as water quality and environmental pollution occurred due to poor drainage of fresh water.

Buttress dams are provided with catching means so that floating materials such as driftwood rooted up due to landslides occur upstream in heavy rain or mountain valleys can be caught without being discharged downstream. However, the buttress dam is a locking means installed at the upper part of the dam, but floating materials such as driftwood caused by heavy rains can be caught without being discharged downstream, but floating materials and foreign substances on the bottom of the dam for a long time. As a result of sedimentation, the dam bottom is increased due to the accumulation of suspended solids and foreign matters, and in the event that a large amount of water is released due to heavy rains, foreign substances such as soil and wood are finally caught. There was a problem that can not be properly exercised. In addition, as these dams are generally constructed of concrete, the surfaces of the dams are always dry, so that no plants or moss can grow on the surfaces of the dams. The dams do not harmonize with the surrounding natural environment. There was a problem that the ecological environment of animals and plants is cut off.

 The present invention is installed in the upper portion of the dam body and the dam body is installed inside the dam body to penetrate the dam body, the drain pipe is installed in the form of 'Λ' to form a bent portion on the upper surface of the bent portion upstream of the dam body The water level control pipe is provided in the surface direction to control the water level of the fresh water, and the drain hole of the 'Λ' shaped drainage pipe is formed close to the bottom of the drip tray so that the water introduced into the drainage pipe passes through the bent portion to the drain hole by gravity. At the same time, the water is smoothly discharged and the water is continuously sucked into the drain pipe, and the inlet of the drain pipe is installed close to the dam bottom, so that the upper water of the fresh water is discharged smoothly through the waterproofing path, and the lower water of the fresh water and the foreign matter and sediment that are settled. The material is drained by the suction pressure of the drainage pipe and the water pressure of the fresh water flowing through the inlet. It smoothly flows in and out through the water, preventing sediment and suspended matter from settling on the dam floor, and inducing smooth discharge of the lower layer water, thereby promoting circulation of fresh water, and the amount of oxygen in the water caused by falling as the water falls through the drain. Improve the water quality of the upstream and downstream sides of the dams, form the ecological framework on the upper part of the dam shoulder, and the vertical, horizontal and inclined ecological passages in the dam body and the ecological holes on the downstream sides of the dams. Forming a connection between the ecological framework, ecological corridor and ecological hole, the water flows into the dam body and the downstream surface at all times and flows through the environment, so that plants and moss can grow throughout the dam to form a natural cover. The purpose is to provide an eco-friendly vegetation dam with an environment.

The present invention has a 'Λ' shaped drainage pipe and a water level control pipe that can smoothly discharge the lower layer of fresh water while maintaining the water level of the dam. The dam body has an ecological path and an ecological hole in an eco-friendly vegetation dam. In this case, the upper water of the fresh water is discharged through the waterproof path formed between the shoulders of the dam, and in order to smoothly discharge the material deposited on the lower water and the bottom of the dam, a 'Λ' shaped drainage pipe is installed inside the dam body to form a bent portion. And a water level control pipe protruding from the top surface of the curved portion to adjust the level of fresh water to the upstream surface of the dam body, and the drainage port of the drain pipe is installed downward toward the bottom of the drip tray to allow water to flow into the drain pipe. Increasing suction power and drainage pressure so that it can be sucked smoothly through this bent part and discharged into the drain pipe, and the bottom water of the dam bottom and sedimentary substance The inlet of the drain pipe is formed to protrude from the upstream surface of the dam body so that the direction of the inlet is directed toward the bottom of the dam to prevent clogging of the inlet by floating materials and foreign matters. The cam is formed in the shape so that the incoming water is spirally sucked in and flows smoothly, and the inlet is blocked by soil, wood chips and foreign substances by installing a 'L' shaped wall from the dam floor at a predetermined distance from the inlet. At the same time, it prevents the inlet from being damaged, and forms an ecological framework to hold soil on the upper part of the dam shoulder so that plants and vines can grow to contain soil and subsoil, and from the ecological framework to the bottom of the dam body. By forming vertical ecological passages which are vertically set at regular intervals, And form a horizontal ecological passage at a predetermined height from the dam floor and connect it to communicate with each other through the vertical ecological passage and the connecting member, and incline from the vertical ecological passage by a predetermined angle to the downstream surface direction of the dam. The ecological hole is formed by the inclined ecological passage on the downstream surface of the dam body by forming the inclined ecological passages extending to each other. Thus, the ecological framework and the vertical, horizontal and inclined ecological pathways and ecological holes By being connected, water can flow into the dam body and flow inside the dam, and water flowing through the ecological hole in the downstream side of the dam can flow, so that plants, vines and moss can grow on the dam body and the entire dam shoulder. It is characterized by being formed.
