Description

호안 블록 설치 구조{Construction structure of shore protection block}Construction structure of shore protection block

본 고안은 호안 블록 설치 구조에 관한 것으로서, 토사의 흐름이나 융기를 방지하여 호안 블록을 안정적으로 유지할 수 있도록 한 호안 블록 설치 구조에 관한 것이다.The present invention relates to a relief block installation structure, and relates to a relief block installation structure that can maintain the relief block stably by preventing the flow or uplift of earth and sand.

종래에 호안 블록을 시공함에 있어서는, 법면의 경사를 백 호(Back hoe)로 정리하고, 정리된 토사 위에 필터 매트(Filter mat)를 하단부에서 상단부로 약간 겹쳐 깐 후, 필터 매트 위에 호안 블록을 하단부터 상단으로 쌓았다.Conventionally, in constructing a raft block, the slope of the surface is rearranged with a back hoe, and the filter mat is slightly overlapped from the bottom to the top of the cleaned soil, and then the raft block is placed on the filter mat. Stacked on top.

첨부도면 도 1에는 상기와 같은 방법으로 시공된 호안 블록 설치 구조가 도시되어 있다.In the accompanying drawings, Fig. 1 shows a relief block installation structure constructed in the above manner.

도 1에 도시된 바와 같이, 종래의 호안 블록 설치 구조는, 토사층(10)위에 우수의 침투를 방지하기 위한 필터 매트(20)가 설치되고, 상기 필터 매트(20) 위에 호안 블록(30)이 쌓여진 형태로 되어 있다.As shown in FIG. 1, in the conventional revetment block installation structure, a filter mat 20 is installed on the soil layer 10 to prevent rainwater from penetrating, and the revetment block 30 is disposed on the filter mat 20. It is in a stacked form.

상기한 호안 블록(10)의 하단에는 호안 블록(10)의 중량을 지지하는 하단근거공(40)이 형성되고, 호안 블록(10)의 상단에는 천단근거공(42)이 형성된다.The bottom root hole 40 for supporting the weight of the raft block 10 is formed at the lower end of the raft block 10, the top end root 42 is formed at the top of the raft block 10.

이와 같은 종래의 호안 블록 설치 구조에 있어서는, 법면이 토사만으로 형성되어 있으므로 토사에 불가항력적으로 포함된 이물질에 의해 표면에 요철이 발생한다. 따라서, 법면의 요철로 인해 호안 블록의 시공성이 나쁘고 깨끗한 면처리가 어려운 단점이 있다.In such a conventional arc relief block installation structure, since the normal surface is formed only by the earth and sand, the unevenness | corrugation generate | occur | produces in the surface by the foreign material contained inevitably to earth and sand. Therefore, due to the irregularities of the surface, there is a disadvantage that the workability of the revetment block is bad and difficult to clean surface treatment.

호안 블록의 시공성이 나쁘고 면처리가 깨끗하지 못한 경우, 우수에 의해 법면토사와 호안블록 사이의 물 흐름에 장애가 발생하거나 지하수에 의한 간극 수압에 의해 토사가 국부적으로 융기되는 현상이 발생한다.In the case of poor workability of the surface protection block and clean surface treatment, the water flow between the surface and the surface protection block is impaired due to rainwater, or the soil is locally raised due to the gap water pressure caused by the groundwater.

토사가 우수에 노출되면 물 흐름의 일정한 경로가 없고, 그에 따라 한 쪽의 토사가 유실되면 그 곳에 물 흐름이 집중되어 토사의 파괴와 유실을 가속화시킨다.When the soil is exposed to rainwater, there is no constant path of water flow, and if one soil is lost, the flow of water is concentrated there, accelerating the destruction and loss of the soil.

토사가 우수에 노출되면 물 흐름의 일정한 경로가 없고, 그에 따라 한 쪽의 토사가 유실되면 그 곳에 물 흐름이 집중되어 토사의 파괴와 유실을 가속화시킨다.When the soil is exposed to rainwater, there is no constant path of water flow, and if one soil is lost, the flow of water is concentrated there, accelerating the destruction and loss of the soil.

또한, 동절기에 토사가 물을 간직하는 경우 토사의 국부적 융기 또는 동결 융해에 의한 국부적 침하 등, 토사의 미세한 유동이 발생한다.In addition, when the soil retains water during the winter season, microfluidic flow of the soil may occur, such as local elevation of the soil or local settlement by freeze-thawing.

그러나, 종래에는 이러한 토사의 유동을 흡수할 수 없어 표면의 호안 블록이 심하게 변형되는 단점이 있었다.However, in the related art, it is not possible to absorb the flow of the earth and sand has a disadvantage that the surface deformed block is severely deformed.

한편, 종래의 필터 매트는 첨부도면 도 2에 도시된 바와 같이, 필터 매트(20)의 단부를 중첩시켜, 중첩된 부분에 U-자형 철선(22)이나 못을 박아 연결하였으므로, 필터 매트(20)의 겹이음이 이탈되거나 틈새가 발생하여, 장기적인 측면에서 우수가 침투되고 이음부위가 처지는 현상이 발생하고, 우수의 침투에 의하여 토사의 흐름이 발생하여 호안 블록(10)이 침하되는 등의 문제가 있었다.On the other hand, the conventional filter mat is overlapping the end of the filter mat 20, as shown in the accompanying drawings, the U-shaped iron wire 22 or nails connected to the overlapping portion, so that the filter mat 20 ) Lap joints are separated or gaps occur, rainwater penetrates in the long-term and sagging of the joints occurs, and the sediment flow is caused by rainwater penetration so that the banks of the revetment block 10 sink. There was.

본 고안은 상기와 같은 종래의 문제를 해소하기 위하여 개발된 것으로서, 호안 블록의 시공성이 양호하고, 토사의 흐름이나 융기를 방지하여 호안 블록을 안정적으로 유지할 수 있도록 한 호안 블록 설치 구조를 제공함에 그 목적이 있다.The present invention was developed in order to solve the above-mentioned conventional problems, the construction of the revetment block is good, and provides a revetment block installation structure that can maintain the revetment block stably by preventing the flow or uplift of earth and sand There is a purpose.
