Description

다목적댐의 종장형 2단수문의 광폭압축방수장치Wide Compression Waterproof Device for Longitudinal Two-Stage Gate of Multi-purpose Dam

본 발명은 다목적댐의 종장형 2단수문의 상, 하단 수분블럭 연결부의 수문의 측면방수에 적용되는 광폭압축고무장치에 관한 것으로써, 특히 종장형 수문높이 10m급 이상의 측면부와 2단연결 결합부의 방수고무를 긴밀하게 밀착고정시켜 수문운용상의 제반조건이 불균형하여 방수조인트에 틈새가 발생되면 광폭압축 고무가 틈새를 보정하여 수문의 누수를 방지할 수 있도록 한 다목적댐의 종장형 2단수문용 광폭압축방수장치에 관한 것이다.The present invention relates to a wide compression rubber device applied to the lateral waterproofing of the water gates of the upper and lower water block connections of the longitudinal two-stage sluice of the multi-purpose dam, in particular, the waterproof rubber of the side portion and the two-stage connecting joint of the height of the longitudinal sluice of 10 m or more When the gap is generated in the waterproof joint due to unbalanced conditions of the hydrological operation, the wide compression rubber compensates for the gap and prevents the leakage of the flood gate. It is about.

일반적으로 종장형 수문높이 10m급 이상의 수분은 측면방수부 길이가 방대하여 수문 및 슬로트에 오차가 증가함에 따라 방수조인트에 틈새가 발생하여 방수가 유지되지 않는 것과, 수문의 2단 연결 방수조인트에 수문의 진동에 따를 흔들림으로 틈새가 발생하여 방수가 유지되지 않는 것을 방지하기 위하여 수문의 방수고무가 토목의 수밀판을 긴밀하게 면착하고 있다.In general, water of more than 10m in height of long hydrologic height does not maintain waterproofness due to gaps in the waterproof joints due to the large length of the side waterproof parts and increases in errors in the floodgates and slots. In order to prevent water gaps from being maintained due to vibration caused by the vibration of the door, the waterproof rubber of the water gate closely adheres to the watertight plates of civil engineering.

종래의 방수장치는 광폭압축 기술이 이루어지지 않아 방수장치에 사용치 못하여 단순히 일반형태의 뮤직노트 타입과 플랫타입으로 사용하고 있는 것이 도 4 내지 도 5에 도시되어 있는데, 이러한 종래의 구조는 도 4에서와 같이 토목에 설치된 수밀판(17)과 수문의 뮤직 노트타입 방수고무(5)가 토목이 권양 슬로트폭(11) 내에서 방수고무 압축 간격(12) 4㎜을 유지하고 있는데, 이러한 종래의 구조는 수문의 높이가 커지면 수문의 변형과 토목슬로트의 시공오차등으로 틈새가 발생하여 4㎜의 방수고무 압축량이 유지되지 못하여 방수가 이루어지지 못하는 문제점이 있었다.Conventional waterproofing device is not used in a waterproof device because the wide compression technology is not made, it is shown in Figures 4 to 5 that is simply used in the general type of music note type and flat type, this conventional structure is shown in Figure 4 As in the watertight plate (17) installed in the civil engineering and music note type waterproof rubber (5) of the sluice civil engineering maintains the waterproof rubber compression interval (12) 4mm within the lifting slot width (11), such a conventional In the structure, when the height of the gate is increased, a gap occurs due to the deformation of the gate and the construction error of the civil slot, so that the waterproof rubber compression amount of 4 mm cannot be maintained, thereby preventing the waterproof.

그리고 상기의 수문변형문제점을 해결하기 위해 수문을 2단블럭으로 각개 높이를 축소하여 설치하면 도 5에서와 같이 상, 하단 수문연결부에 플랫타입 방수고무(16)을 사용 결합하여 상, 하단 수문 결합간격(13)부에 방수고무압축간격(14) 4㎜을 유지하는데, 수문의 진동에 의해 흔들림 현상으로 틈새가 발생하여 4㎜의 방수고무 압축량이 유지되지 못하여 방수가 이루어지지 않아 누수가 되는 문제점도 있었다.And in order to solve the hydrologic deformation problem, when installing the water gate by reducing the height of each of the two-stage block, combined with the upper and lower hydrology by using a flat type waterproof rubber (16) to the upper and lower hydrologic connections as shown in FIG. The waterproof rubber compression interval 14 is maintained at the interval 13, but a gap occurs due to the shaking phenomenon due to the vibration of the water gate, and the waterproof rubber compression amount of 4 mm is not maintained, which causes water leakage to occur. There was also.

또한, 도 4에서와 같이 방수고무의 설치위치가 권양슬로트폭(11) 내부에 장치됨으로 인하여 댐이 경간방류폭(9)보다 길어진 수압폭을 유지하므로 수압계 산측면에서 추가적인 부수압이 발생되는 문제점이 있었다.In addition, since the installation position of the waterproof rubber is installed inside the hoisted slot width 11, as shown in FIG. 4, since the dam maintains the hydraulic pressure length longer than the span discharge width 9, additional hydraulic pressure is generated at the hydraulic pressure side. There was a problem.

일반적으로 종장형의 2단분할 수문을 측면부 방수길이가 10m 이상으로 매우 큼으로 인하여 방수조인트에 틈새가 발생되는 것과 수문의 상, 하단 연결결합부의 진동과 비틀림 등에 의하여 방수조인트에 틈새가 발생되는 것을 방지하여 방수를 긴밀하게 유지할 수 있도록 한 종장형 2단 수문용 관폭압축 방수장치를 제공하는 것으로, 본 발명은 종장형 수문의 측면부와 토목의 경간방류폭에 방수고무와 수밀판을 면착시키는 광폭압축장치를 구성함에 있어서, 앵글타입의 굽힘탄성이 좋은 측면방수고무를 패드플레이트가 구비된 표면에 압착형 클램핑플래이트와 진개물 차단가드를 고정부재를 압착하고, 수문의 상, 하단 연결결합부에는 원호형의 오메가타입 방수고무를 압착형 클래핑 플래이트와 진개물차단가드를 고정부재로 압착하여 스테인래스볼트, 너트와 방수와셔를 결합부재로 상기 광폭압축고무를 정렬하는 다목적댐의 종장형 2단 수문의 광폭압축방수장치에 의해 달성된다.In general, the length of the two-stage split sluice of the longitudinal type is more than 10m, so that a gap occurs in the waterproof joint and a gap occurs in the waterproof joint due to the vibration and twist of the upper and lower coupling parts of the sluice. To provide a water-proof compression device for the longitudinal type two-stage sluice to prevent water tightly to maintain the waterproof, the present invention is a wide-width compression to adhere the waterproof rubber and watertight plate to the side discharge of the longitudinal gate and the span of civil engineering In constituting the device, angle-type bending elastic rubber having good elasticity on the surface of the pad plate is pressed on the surface of the pad plate with the pressing clamping plate and the anti-tuck blocking guard. The arc-shaped omega type waterproof rubber is pressed into the clamping clapping plate and the anti-trailer blocking guard with the fixing member. It is achieved by the longitudinal two-stage sluice waterproofing device of a multi-purpose dam that aligns the wider compression rubber with a nut and a waterproof washer.

도 1 내지 도 2에는 본 발명에 따른 다목적 댐이 종장형 2단 수문의 광폭압축방수장치가 도시되어 있는데, 이 광폭압축방수 장치는 광폭압축 구조의 앵글형(1)과 오메가형(6)의 방수고무를 사용하여 변형과 진동에 의해 틈새를 보정하여 방지하고, 토목의 수밀판과, 수문의 방수고무를 완전밀착하여 우수한 방수효과를 얻을 수 있게 하는 것이다.1 to 2, the multi-purpose dam in accordance with the present invention is a wide compression waterproof device of the longitudinal two-stage sluice, this wide compression waterproof device is waterproof in the angle type (1) and omega type (6) of the wide compression structure Rubber is used to prevent gaps by deformation and vibration, and it is possible to obtain excellent waterproofing effect by closely contacting the watertight plates of civil engineering and the waterproofing rubber of water gate.

그리고 본 발명은 광폭압축고무의 상단에 진개물보호가드(4)를 설치하여 진개물 및 토사유입에 의한 광폭장치의 기능저하와 손상으로부터 보호되도록 배치하는 것이다.In addition, the present invention is to arrange the protective device guard 4 on the upper end of the wide compression rubber to be protected from the functional degradation and damage of the wide device by the infiltration and sediment inflow.

또한 본 발명은 댐 경간이 방류폭(9)에 맞추어 광폭압축방수장치(1)의 수압폭을 유지하므로 전수압에 대한 추가적인 부수압 발생이 상쇄되는 경제적인 장소에 설치하게 되는 것이다.In addition, the present invention is to be installed in an economical place where the dam span is maintained in the hydraulic pressure width of the wide compression waterproofing device 1 in accordance with the discharge width (9) to offset the occurrence of additional secondary pressure to the total hydraulic pressure.

도 1을 참조하여 설명하면 다음과 같다.Referring to Figure 1 as follows.

댐의 경간 방류폭(9)에 매설된 토목부 수밀판(17)과 경관방수고무 압축간격(10)이 유지되도록 앵글타입측면용 방수고무(1)을 패드플래이트(2)가 구비된 수문측면에 압착형 클램핑플래이트(3)와 진개물차단가드(4)을 결합하여 스테인레스 볼트, 너트(8)에 방수와셔(7)를 고정부재로 압착하여 정렬시키면 광목압축고무의 탄성력에 의하여 수밀판과 건조상태에서 면착이 이루어지고 댐에 수위가 증가하면 이 면착부 고무압착력(=0.3TON/m)이 작용하여 긴밀하게 압착됨에 따라 방수가 유도된다.The water-tight side with the pad plate (2) is equipped with an angle type side waterproofing rubber (1) so as to maintain the civil engineering part watertight plate (17) buried in the span discharge width (9) of the dam and the landscape waterproof rubber compression interval (10). Compress the clamping plate (3) and the lock guard (4) on the stainless steel bolt and nut (8) to squeeze and align the waterproof washer (7) with the fixing member. When the adhesion is made in the dry state and the water level is increased in the dam, the rubber adhesion force (= 0.3TON / m) of the adhesion portion is applied to induce water tightness as it is closely compressed.

상기와 같은 조립이 완료되면 앵글타입 측면용 방수고무(1)의 광폭압축간격(25㎜)이 유지되어 수문이 불규형적으로 이동되어도 광폭압축력이 보정하여 틈새가 없어지게 된다.When the assembly is completed as described above, the wide compression interval (25 mm) of the waterproof rubber (1) for the angle type side is maintained so that even if the water gate is moved irregularly, the wide compression force is corrected so that there is no gap.

또한 광폭압축고무에 부착된 진개물차단가드(4)는 각종의 부유물과 토사의 유입을 차단하여 광폭압축고무의 압축보정 작용이 유지되도록 보호하게 된다.In addition, the anti-trail material blocking guard (4) attached to the wide compression rubber to protect the compression correction action of the wide compression rubber by blocking the inflow of various floats and soil.

도 2을 참조하여 설명하면 다음과 같다.Referring to Figure 2 as follows.

종장형 수문의 2단 분할된 수문블럭 연결부의 상, 하단 수문결합간격(13)에 맞추어 광폭압축고무의 압축간격(14)이 유지되도록 오메가타입 연결용 방수고무(6)을 패드플래이트가 구비된 상, 하단의 연결부에 압착형 클램핑플래이트(3)와 진개물차단가드(4)을 결합하여 스테인레스 볼트, 너트(8)와 방수와셔(7)를 고정부재로 압착하여 정렬시키면 광폭압축고무의 탄성력이 유지된 채 원호형태로 압착됨에 따라 방수가 유도된다.The pad plate is provided with an omega type waterproof rubber (6) so that the compression interval (14) of the wide compression rubber is maintained in accordance with the upper and lower sluice-coupling intervals (13) of the two-stage sluice block connecting portion of the longitudinal hydrology. Combining the crimping clamping plate (3) and the lock blocking guard (4) at the upper and lower ends to align the stainless bolt, nut (8) and waterproof washer (7) with a fixing member to align the elastic force of the wide compression rubber The water is induced as it is compressed in the form of an arc while being kept.

상기와 같은 조립이 완료되면 오메가타입 연결용 방수고무(6)가 원호상태로 탄성력이 유지되어 수문결합부가 불균형적으로 이동되어도 원호압축력이 보정하여 틈새가 없어지게 된다.When the assembly is completed as described above, the Omega type waterproof rubber 6 is maintained in an arc state and the elastic force is maintained, so that the arc compression force is corrected even if the hydrological coupling portion is disproportionately moved to eliminate gaps.

또한, 오메가타입방수 고무에 부착된 진개물차단가드(4)는 각종의 부유물과 토사의 유입을 차단하여 원호압축고무의 압축보정 작용이 유지되도록 보호하게 된다.In addition, the anti-trail blocking guard (4) attached to the omega-type waterproof rubber is to protect the compression correction action of the arc compression rubber by blocking the inflow of various suspended matter and soil.

따라서, 종장형의 높이 10m 급이상 2단 수문을 설치하여 수문의 운영을 불균형 현상 즉, 수문의 변형, 수문개폐시의 진동과 권양슬로트의 오차 등으로 틈새가 발생되면 수문의 측면은 앵글형의 방수고무가 틈새를 보정하고 수문의 2단 연결부는 오메가형이 방수고무가 틈새를 보정하여 틈새가 없어지므로 토목의 수밀판과 광폭압축방수고무가 연속적으로 긴밀한 압착이 되어 방수가 유지되는 것이다.Therefore, the installation of two-stage gates with heights of 10m or more in height length makes the operation of the gate unbalanced, i.e. when the gap occurs due to the deformation of the gate, the vibration of the gate and the error of the hoisting slot, the side of the gate is angled. The waterproof rubber compensates for gaps, and the two-stage connection of the sluice is omega type, and the waterproof rubber compensates for gaps so that there is no gap, so the watertight plates of civil engineering and wide compressive waterproof rubbers are continuously pressed tightly to maintain waterproofness.

도 1 내지 도 2를 참조하여 본 발명의 효과에 관해 설명하겠다.With reference to Figures 1 to 2 will be described the effect of the present invention.

종장형의 높이 10m급 이상의 2단 수문에 사용되는 방수고무를 광폭압축흡수가 가능하게 하여서 수문운용의 불균형 현상에 의한 수문의 변형과 진동 등으로 틈새가 발생하여도 광폭압축방수고무가 보정하여 항상 압착조건이 구비되어 수문의 방수를 지속적으로 유지할 수 있는 것이다.The waterproof rubber used for the two-stage sluice of 10m or more in height is able to absorb wide-width compression, so that even if a gap occurs due to deformation and vibration of the gate due to the imbalance of hydrological operation, the wide-compression waterproof rubber is always corrected. It is equipped with a crimping condition to maintain the waterproof of the water gate continuously.

그리고 본 발명은 광폭압축방수고무의 상단에 진개물차단가드를 설치하여 진개물 및 토사유입에 의해 광폭장치의 기능저하와 손상으로부터 보호되도록 배치하고 또한, 본 발명은 댐경간의 방류폭에 맞추어 방수고무의 수압폭을 유지하므로 수압계산 측면에서 추가적인 부수압 발생이 상쇄되는 경제적인 장소에 설치하게 되는 것이다.In addition, the present invention is installed so as to protect from the functional degradation and damage of the wide width device by installing a seismic barrier blocking guard on the upper end of the wide compression waterproof rubber, and the present invention is waterproof according to the discharge width between the dam span Since the pressure range of the rubber is maintained, it is installed in an economical place where additional side pressure generation is canceled in terms of pressure calculation.

따라서, 종래와 같이 종장형의 수문에 광폭압축장치가 없는 일반형의 뮤직노트 타입과 플랫타입 방수고무를 사용하여 수문변형과 진동 그리고 슬로트 오차에 의한 틈새발생에 따른 누수가 발생되는 것을 방지함과 동시에 종장형 높이 10m급 이상의 2단 수문에 대한 광폭압축 방수기술이 확보되어 수문의 높이에 제한됨이 없이 방수가 가능하여 경제적인 수문설계와 댐운영 조건을 향상 시킬 수 있는 것이다.Therefore, by using the general type of music note type and flat type waterproof rubber which do not have a wide-width compression device in the longitudinal type of floodgate, it is possible to prevent the leakage caused by the gap caused by the deformation and vibration of the floodgate and the slot error. At the same time, wide-compression waterproofing technology for two-stage sluice with a height of more than 10m height is secured, which enables waterproofing without being limited to the height of the sluice, thereby improving economical hydrological design and dam operating conditions.
