본 발명은 철근콘크리트 슬래브식 차수벽을 가지는 표면차수벽형 필댐에 관한 것으로, 댐 제체의 축제(築堤)시 기 매입 설치한 다수의 앵커형 구조물에 차수벽을 연결하여 타설함으로써 차수벽의 활동을 방지함은 물론 제체의 상류측 사면을 종래의 표면차수벽형 필댐에 비하여 급경사로 시공할 수 있도록 한 것이다.The present invention relates to a surface-grade wall-type dam having a reinforced concrete slab-type barrier wall, which prevents the operation of the barrier wall by connecting and placing the barrier wall to a plurality of anchor-type structures that are installed and installed during the festival of the dam body. The upstream slope of the body can be constructed at a steep slope compared to the conventional surface-order wall dam.

표면차수벽형 필댐(fill dam)은 도 1에서와 같이, 토석(土石)으로 축제된 제체(10)의 상류측 사면에 불투수소재로 구성된 차수벽을 설치하여 저수지를 유지하는 댐의 형식으로서, 동 도면에는 석괴(12)로 축제된 제체(10)와 콘크리트슬래브로 구성된 차수벽이 적용되는 콘크리트 표면차수벽형 석괴댐이 도시되어 있다.Surface dam wall fill dam (fill dam), as shown in Figure 1, is a type of dam to maintain the reservoir by installing a water-repellent wall made of impermeable material on the upstream side of the body 10, which is festively earthen In the drawing, a concrete surface order wall type stone ingot dam to which the order wall composed of the sieve 10 and the concrete slab applied to the stone ingot 12 is applied is shown.

표면차수벽형 필댐에 있어서 차수벽의 재료로는 철근콘크리트, 아스팔트 등이 사용되는데, 도 1에서와 같이, 콘크리트차수벽(11) 외에 표면차수효과를 극대화하기 위한 차수막(14)이 2중으로 시공되기도 하며, 차수막(14)으로는 아스팔트 등이 주로 사용된다.Reinforced concrete, asphalt, etc. are used as the material of the order wall in the surface order wall type dam, and in addition to the concrete order wall 11, the order film 14 for maximizing the surface order effect may be constructed in double. As the order film 14, asphalt or the like is mainly used.

이러한 표면차수벽형 필댐 특히 석괴(12)댐은 제체(10)를 구성하는 석괴(12)가 부착력을 전제로 성토되지 않으므로 침수시 제체(10)의 구조에 미치는 영향이 미미하여 다우(多雨)지역에 댐을 시공함에 있어서 매우 유리하며, 같은 맥락으로 여타 필댐에 비하여 수위의 급강하에 대한 안전도가 매우 크므로 양수발전소 하부 지(下部池) 등 수면변동이 큰 저수지에 적합한 장점이 있다.Such surface-order wall dams, particularly the lumps (12) dams, are not built up on the premise of the adhesion of the lumps (12) constituting the body (10). The construction of the dam is very advantageous, and in the same vein, the safety of the water drop is much higher than that of other fill dams, so it is suitable for reservoirs with large water fluctuations such as the lower part of the pumping station.

그러나, 표면차수벽형 필댐에 있어서 차수효과를 발현하여 저수지를 유지하는 구성요소는 상류측 사면의 콘크리트차수벽(11)이 유일한 바, 이 콘크리트차수벽(11)과 댐 제체(10)의 안정적 결합이 매우 중요하나, 콘크리트차수벽(11)은 제체(10) 상류측 사면과 콘크리트차수벽(11)간에 작용하는 마찰력과 댐 상류측 하단에 설치된 프린스(plith)(13)에 의해서만 지지되는 구조로서, 활동(sliding)이나 파랑 및 유빙(流氷)으로 인한 충격에 취약할 수 밖에 없는 문제점이 있었다.However, in the surface order wall type dam, the only component to maintain the reservoir by expressing the order effect is that the concrete order wall 11 and the dam body 10 have a stable coupling. Importantly, the concrete containment wall 11 is a structure supported only by the friction force acting between the upstream side of the body 10 and the concrete order wall 11 and the prince 13 installed at the lower side of the upstream side of the dam. ), But there is a problem that can not be vulnerable to the impact caused by blue waves and drift ice (流 氷).

따라서, 표면차수벽형 필댐에 있어서 상류측 사면의 경사는 완만하게 구성할 수 밖에 없었으며, 댐의 높이에도 제한이 있을 수 밖에 없어 통상 100m 이상의 높은 댐에는 적용이 불가능한 것이 정설이다.Therefore, the slope of the upstream slope is inevitable in the surface order wall dam, and the height of the dam is inevitably limited, and is generally not applicable to a dam of 100 m or more.

본 발명은 전술한 문제점을 감안하여 창안한 것으로, 표면차수벽형 필댐의 제체 축제시 다수의 앵커를 소정간격으로 매입하여 설치하되 그 두부(頭部)가 상류측 사면에 노출되도록 한 후, 콘크리트차수벽의 시공시 노출된 앵커의 두부에 콘크리트차수벽을 타설하여 고정함으로써, 콘크리트차수벽의 활동을 방지하고 구조적 안정성을 확보할 수 있도록 한 것이다.The present invention has been made in view of the above-described problems, and when installing a plurality of anchors at predetermined intervals during the festival festival of the surface-order wall-type dam dam, the head is exposed to the upstream slope, the concrete-order wall By placing concrete anchor walls on the heads of the anchors exposed during construction, the concrete order walls prevent activity and ensure structural stability.

또한, 상기 앵커를 구성함에 있어서는 장방형의 매설판 양측 변에 한 쌍의 지지빔 선단부를 고정하고, 이들 지지빔의 두부에는 다수의 부착공을 천공함으로써, 매설판에 작용하는 토압에 의하여 앵커의 고정효과를 배가하고, 부착공을 통하 여 콘크리트차수벽과 앵커간의 부착력을 증대할 수 있도록 하였다.Further, in constructing the anchor, a pair of supporting beam tips are fixed to both sides of the rectangular buried plate, and a plurality of mounting holes are drilled in the heads of these supporting beams to fix the anchor by earth pressure acting on the buried plate. The effect was doubled and through the attachment hole, it was possible to increase the adhesion between the concrete order wall and the anchor.
