The side end faces are not spaced apart, and the stepped grooves are formed at both ends between the spaced flow induction blocks, and fastening grooves are formed to allow the flow rate reduction panel to be inserted into the opposite sides of the stepped jaw. Inflow hole to allow river water to flow through and outflow hole to allow river water to flow into the downstream step Although the diameter of the inlet hole is larger than the diameter of the outlet hole, the fixed anchor insertion hole is formed in the bottom anchoring hole is inserted, the flow rate reduction panel is inserted into the fastening groove to reduce the flow rate of the river water to protect the riverbed The present invention relates to a river bed bottom block installation structure for reduction.

일반적으로 하천은 옹벽과 제방을 구축하여 홍수 등에 의한 재난에 대비하고 있으나, 하천의 하상은 자연적으로 형성된 형태를 그대로 유지하고 있어 홍수시와 같이 수량이 많아지고 유속이 증가하게 되면 하상의 토사는 물론 자갈과 바위가 하천 하류로 흘러내리게 되므로 하상이 파이거나 제방 하단이 침식되어 제방의 붕괴 를 유발하는 등의 문제점이 있다.In general, rivers are built in retaining walls and embankments to prepare for disasters caused by floods.However, riverbeds maintain their naturally formed forms, so when the quantity increases and the flow rate increases, Since pebbles and rocks flow down streams, there are problems such as piling of riverbeds or erosion of the bottom of the banks, causing the banks to collapse.

이러한 문제점을 해결하기 위하여 제방의 밑부분에는 침식을 방지하기 위한 시설물이 설치되거나 암석류를 적층하는 방법이 많이 사용되고 있다.In order to solve this problem, a facility for preventing erosion is installed at the bottom of the embankment or a method of stacking rocks is used.

그러나, 상기의 방법은 제방의 밑부분을 보호하는 데에는 어느 정도 효과가 있지만 하상 자체를 보호하는 시설물은 거의 없는 실정이다.However, the above method is somewhat effective in protecting the base of the embankment, but there are few facilities that protect the bed itself.

뿐만 아니라, 하천수는 하상에서 하층으로 여과되고, 하류로 흐르면서 수생식물에 의한 자연정화, 흐름에서 산소의 용존으로 인한 자연정화 등과 같은 자연정화 기능이 수행되고 있지만 하상이 평편하게 유지되는 경우에는 자연정화 능력이 저하되는 문제점이 있었다.In addition, the river water is filtered from the bottom to the lower layer and flows downstream to perform natural purification by aquatic plants and natural purification due to the dissolved oxygen in the flow, but when the riverbed is flat, There was a problem that the ability is reduced.

따라서, 본 발명의 목적은 하천수의 유속을 저하시켜 하천의 하상을 보호함과 동시에 하천수에 용존 산소량을 증가시켜 자연 정화 능력이 향상될 수 있도록 하는 수중생명체의 은신과 이동이 가능하게 함으로써 생태계를 보호할 수 있도록 하는 유속감소용 하천 저면 바닥블록 설치구조를 제공하는 데 있다.Accordingly, an object of the present invention is to protect the ecosystem by enabling the hiding and movement of underwater life to improve the natural purification ability by reducing the flow rate of the river water to protect the riverbed of the stream and at the same time increase the amount of dissolved oxygen in the river water It is to provide a river bottom floor installation structure for reducing the flow rate.

상술한 목적 뿐만 아니라 용이하게 표출될 수 있는 다른 목적들을 달성하기 위하여 본 발명에서는 하천수가 저면바닥블록의 유입홀과 유출홀로 또는 하상으로 유도될 수 있도록 경사면이 형성되어 있고, 하천수의 바닥 수위를 상이하게 하기 위한 요홈이 형성되어 있으며, 하상에 고정하기 위한 고정앙카 삽입공이 형성되어 있고, 고정앙카 삽입공을 통하여 타격 삽입되어 하상에 견고히 지지시키는 고정앙카로 구성되는 유속유도블록을 경사면이 설치되지않은 측단면이 대향되도록 이격설 치하고, 이격설치된 유속유도블록 사이에 양측단에 단턱이 형성되어 있고 단턱의 대향되는 면에 유속감속패널이 삽입 체결될 수 있는 체결홈이 형성되며, 상류측 단턱에 하천수가 유입되도록 하는 유입홀이 통공되고 하류측 단턱에 하천수가 유출되도록 하는 유출홀이 통공되어지되 유입홀의 직경이 유출홀의 직경보다 크게 형성되며, 하상에 고정 앙카가 삽입되는 고정앙카 삽입공이 형성되고, 체결홈에 유속감속패널이 삽설되므로서 하천수의 유속을 감소시켜 하상을 보호하도록 하는 효과와 와류가 형성되어 용존산소의 양이 증가되어 자연정화 능력이 향상되는 효과를 얻을 수 있었다.In order to achieve the above object as well as other objects that can be easily expressed in the present invention, the inclined surface is formed so that the river water can be led to the inlet and outlet holes of the bottom bottom block, or to the riverbed, and the bottom water level of the river water is different Grooves are formed for the purpose, and a fixed anchor insertion hole is formed for fixing to the bottom, and a flow velocity induction block consisting of a fixed anchor for firmly supporting the bottom by being inserted into the blow through the fixed anchor insertion hole has no inclined surface. The side sections are spaced apart to face each other, and stepped grooves are formed at both ends between the flow-induced blocks spaced apart from each other, and fastening grooves are formed to allow the flow-rate deceleration panel to be inserted into the opposite sides of the stepped jaws. An inlet hole that allows river water to flow in and a stream that allows river water to flow out on a downstream side step The hole is drilled through, but the diameter of the inlet hole is larger than the diameter of the outlet hole, and the fixed anchor insertion hole into which the anchor anchor is inserted is formed, and the velocity reduction panel is inserted into the fastening groove to reduce the flow velocity of the river water to protect the riverbed. The effect and the vortex is formed to increase the amount of dissolved oxygen was able to obtain the effect of improving the natural purification ability.

본 발명을 첨부 도면에 의거하여 좀 더 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명의 유속감소용 하천 저면 바닥블록이 설치된 상태의 개념도이고, 도 2는 본 발명의 유속감소용 하천 저면 바닥블록의 분해사시도이며, 도 3은 본 발명의 유속감소용 하천 저면 바닥블록이 설치된 상태의 개략적인 사시도이다.1 is a conceptual diagram of a state in which a river bottom bottom block for reducing the flow rate of the present invention is installed, Figure 2 is an exploded perspective view of a river bottom bottom block for reducing the flow rate of the present invention, Figure 3 is a river bottom bottom for reducing the flow rate of the present invention It is a schematic perspective view of a state with a block installed.

본 발명에 따른 유속감소용 하천 저면 바닥블록의 설치구조는 하천수가 저면바닥블록(20)의 유입홀(25)과 유출홀(26)로 또는 하상으로 유도될 수 있도록 경사면(11)이 형성되어 있고, 하천수의 바닥 수위를 상이하게 하기 위한 요홈(12)이 형성되어 있으며, 하상에 고정하기 위한 고정앙카 삽입공(13)이 형성되어 있고, 고정앙카 삽입공(13)을 통하여 타격 삽입되어 하상에 견고히 지지시키는 고정앙카(14)로 구성되는 유속유도블록(10)을 경사면(11)이 설치되지 않은 측단면이 대향되도록 이격설치하고, 이격설치된 유속유도블록(10) 사이에 양측단에 단턱(21, 22)이 형성 되어 있고 단턱(21, 22)의 대향되는 면에 유속감속패널(30)이 삽입 체결될 수 있는 체결홈(23, 24)이 형성되며, 상류측 단턱(21)에 하천수가 유입되도록 하는 유입홀(25)이 통공되고 하류측 단턱(22)에 하천수가 유출되도록 하는 유출홀(26)이 통공되어지되 유입홀(25)의 직경이 유출홀(26)의 직경보다 크게 형성되며, 하상에 고정 앙카(27)가 삽입되는 고정앙카 삽입공(28)이 형성되고, 체결홈(23, 24)에 유속감속패널(30)이 삽설 구성된 것으로 특징지워진다.The installation structure of the river bottom bottom block for reducing the flow velocity according to the present invention is formed with an inclined surface 11 so that river water can be guided to the inlet hole 25 and the outlet hole 26 of the bottom bottom block 20 or to the lower bed And, the groove 12 for different the bottom water level of the river water is formed, the fixing anchor insertion hole 13 for fixing the lower phase is formed, the blow insert through the fixed anchor insertion hole 13 is lowered The flow velocity guide block 10, which is composed of a fixed anchor 14, which is firmly supported on the side, is spaced apart from each other so that side cross-sections on which the inclined surface 11 is not provided face each other, and stepped on both sides between the flow velocity guide blocks 10 spaced apart from each other. (21, 22) is formed and the fastening grooves (23, 24) for the fastening of the flow rate reduction panel 30 is formed on the opposite surface of the step (21, 22), the upstream step (21) An inflow hole 25 through which the river water flows is passed through the downstream side step 22. An outflow hole 26 through which the water flows out is passed through, but the diameter of the inflow hole 25 is formed larger than the diameter of the outflow hole 26, and a fixed anchor insertion hole 28 into which the anchoring anchor 27 is inserted. ) Is formed, and the flow rate reduction panel 30 is inserted into the fastening grooves 23 and 24.

유속유도블록(10)에는 경사면(11)이 설치되므로서 저면바닥블록(20)으로 하천수가 용이하게 유입되도록 함과 동시에 유출홀(26)로부터 유출되는 하천수가 하상으로 용이하게 흘러 들어가게 한다. 또한, 하천수의 바닥 수위를 상이하게 하기 위한 요홈(12)이 형성되어지되 유입홀(25)과 연결되도록 하지 않고 상류측 단턱(21)에 막히게 하므로서 요홈(12)으로 유입된 하천수는 단턱에 의하여 속도가 일차적으로 감속되도록 함과 동시에 와류가 형성되어 용존 산소량이 풍부해지도록 한다.Since the inclined surface 11 is installed in the flow rate induction block 10, the stream water is easily introduced into the bottom bottom block 20, and at the same time, the river water flowing out of the outlet hole 26 easily flows into the riverbed. In addition, the groove 12 is formed to be different from the bottom water level of the river water, but the river water flowing into the groove 12 is blocked by the upstream side step 21 without being connected to the inlet hole 25 by the step At the same time, the velocity is primarily decelerated, while vortices are formed to enrich the amount of dissolved oxygen.

뿐만 아니라 유입홀(25)로 유입되지 않고 상류측 단턱(21)에 부딛치는 하천수는 유입홀(25)로 직접 통과되는 하천수에 비하여 유속이 감소되며, 유입홀(25)로 유입된 하천수는 유속 감지패널(30)을 따라 굴곡지게 흐르게 되므로서 유속이 저하되어 본 발명의 유속감소용 하천 저면 바닥블록의 설치구조와 근접하게 흐르는 하천수 즉, 하상의 바로 윗부분을 흐르는 하천수의 속도는 현저하게 감소되게 되므로 하상이 보호된다.In addition, the river water that does not flow into the inflow hole 25 and hits the upstream side step 21 has a reduced flow rate compared to the river water that passes directly through the inflow hole 25, and the river water introduced into the inflow hole 25 has a flow rate. As the flow rate is lowered along the sensing panel 30, the flow rate is lowered, so that the speed of the stream water flowing in close proximity to the installation structure of the bottom block for reducing the flow rate of the present invention, that is, the speed of the stream water flowing directly above the lower bed is significantly reduced. The bed is protected.

유속유도블록(10) 및 저면바닥블록(20)은 고정앙카(14, 27)가 하상에 깊게 삽입되어 고정되므로서 견고하게 지지된다.The flow velocity guide block 10 and the bottom bottom block 20 are firmly supported as the anchoring anchors 14 and 27 are deeply inserted into and fixed to the bottom.

유속 감속 패널(20)은 "S"자 형태로 굴곡진 것을 사용하는 것이 하천수의 유속을 저하시키면서도 저면바닥블록(20)에 큰 압력이 전달되지 않아 내구성을 향상시킬 수 있어 바람직하지만, 이에 한정되는 것은 아니다.It is preferable that the flow rate deceleration panel 20 bends in the form of "S" to reduce durability of the river water and to improve durability because a large pressure is not transmitted to the bottom bottom block 20, but is limited thereto. It is not.

또한, 유입홀(25)의 직경을 유출홀(26)의 직경보다 크게 형성시키므로서 하류측 단턱(22) 상부로 유입홀(25)을 통과한 하천수도 일부가 월류되도록 하여 하천수의 흐름 방향을 전환시키므로서 하천수의 유속이 감지되게 된다.In addition, the diameter of the inflow hole 25 is formed to be larger than the diameter of the outflow hole 26, so that a portion of the river water passing through the inflow hole 25 to the upper side of the stepped portion 22 is also overflowed so that the flow direction of the river water flows. By converting, the flow rate of the river water is detected.

한편, 본 발명의 유속감소용 하천 저면 바닥블록 주위에서는 하천수의 흐름에 와류가 형성되고, 이로 인하여 용존산소량이 증가함으로써 수생식물의 생육을 도와 수생식물에 의한 자연정화 능력을 향상시킴과 동시에 증가된 용존 산소에 의하여 산화 작용이 향상되어 자연정화 능력이 향상된다.On the other hand, the vortex is formed in the flow of the river water around the bottom block bottom of the stream for reducing the flow rate of the present invention, thereby increasing the dissolved oxygen amount to help the growth of aquatic plants and to increase the natural purification ability by the aquatic plants. Oxidation is enhanced by dissolved oxygen, which improves natural purification capacity.

The fixed anchor insertion hole is formed, and the flow velocity guide block composed of the fixed anchor that is firmly supported by the blow anchor is inserted through the fixed anchor insertion hole so as to be spaced apart from each other so that the side cross sections of the inclined surface are not installed. Steps are formed at both ends between the blocks, and fastening grooves for fastening the velocity reduction panel are formed on opposite sides of the step, and inflow holes for allowing river water to flow into the upstream step are provided in the downstream step.
