Abstract

The inflatable dam has a flexible closed envelope(7) attached to a foundation(9), which in turn is arranged across a river to form a dam when inflatable. It has an air inlet and discharge(11) pipe with one end feeding into the bottom of the envelope. The other end of the discharge pipe(13) has a branch pipe(14) with its open end submerged in water at a predetermined level. This corresponds to the air pressure in the envelope when the dam is inflated. An air pressure detecting pipe(12) has one end leading from a side of the envelope and its other end connected to a vertical portion of the branch pipe.

Description

안전장치를 구비하는 가요성막(可搖性膜)으로 제조된 제언(提堰)Suggestions made of flexible membranes with safety devices

제1도는 종래의 공기 팽창식 가요성막으로 제조된 제언의 안전장치의 설명용 횡단면도.1 is a cross-sectional view for explaining the safety device of the suggestion made of a conventional air inflatable flexible membrane.

제2도는 본 발명의 공기팽창식 가요성막으로 제조된 제언의 안전장치의 설명용 횡단면도.2 is a cross-sectional view for explaining the safety device of the suggestion made of the air-expandable flexible film of the present invention.

본 발명은 고무를 입힌 직물등 가요성막으로 제조된 제언(공기 팽창식)에 관한 것으로 자세하게는 안정장치를 구비한 가요성막으로 제조된 제언(둑)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a suggestion made of a flexible film such as rubber coated fabric (air inflatable), and more particularly, to a suggestion made of a flexible film having a stabilizer.

종래의 이런 종류의 장치는 제1도에 표시한 바와 같다.This type of conventional device is as shown in FIG.

제1도에 있어서, (7)은 제언을 형성하는 가요성막으로 제조된 포피(包被) 예를들면 고무를 입힌 직물제 포피(예를들면 일본 특공소 40-11702호, 특공소 44-2371호 참조)이고, (9)는 하상부(河床部) 콘크리트, (8)의 법부(法部) 콘크리이트, (12)는 내압검지관(포피저부로부터 수평방향으로 연장하여 있다)을 나타내며, (4)는 내압검지용 압력계, (11)은 주배기관(포피저부로부터 수평방향으로 연장함), (13)은 주기관(注氣管), (1)은 주기(注氣)밸브, (6)은 포피(7)을 팽창시키기 위한 송풍기, (14)는 분기관, (3)은 수봉관(水封管)(또는 수조), (5)는 수봉관에 저수된 물, (2)는 배기밸브, (10)은 조작실, (15)는 주배기관의 수평부를 표시한다.In Fig. 1, reference numeral 7 denotes a foreskin made of a flexible film forming a suggestion, for example, a rubberized fabric foreskin (e.g., Japanese JP-A 40-11702, JP-44-2371). (9) represents the lower concrete (8), the concrete concrete of (8), (12) represents the pressure-resistant detection tube (extending in the horizontal direction from the foreskin portion), (4) is pressure gauge for internal pressure detection, (11) is the main exhaust pipe (extending horizontally from the foreskin section), (13) is the main pipe, (1) is the main valve, (6 Is a blower for inflating the foreskin (7), (14) is a branch pipe, (3) is a water pipe (or water tank), (5) is water stored in the water pipe, and (2) Exhaust valve 10 denotes an operation chamber and 15 denotes a horizontal portion of the main exhaust pipe.

포피(7)내의 내압이 허용설계 압력을 넘으면 허용설계압력에 상당하는 수두(水頭)(H)의 물(5)를 저수한 수봉관(3)에 삽입된 주배기관(11)의 분기관(14)의 선단 개구부로부터 잉여공기가 배출되어 포퍼(7)내의 압력을 허용설계 압력이하로 유지하는 기구로 되어 있다.If the internal pressure in the foreskin 7 exceeds the allowable design pressure, the branch pipe of the main exhaust pipe 11 inserted into the water seal pipe 3 storing water 5 of the head H corresponding to the allowable design pressure ( Excess air is discharged from the tip opening of 14) to maintain the pressure in the popper 7 below the allowable design pressure.

그러나 제언을 팽창, 기립시켜 장시간 사용하면 포피내의 공기에 함유된 하천수에 의하여 냉각되어 응축하고 그 물방울이 드레인으로서 주배기관(11)에 고인다. 이 드레인이 주배기관의 수평부(15)를 채우고 장치가 작동할 경우를 생각하면 포피내의 공기압력에 의해서 드레인이 주배기관의 수직부분(16)을 밀어올리지 않으면 안된다.However, if it is used for a long time by expanding and standing up the proposal, it is cooled and condensed by the river water contained in the air in the foreskin and the water droplets are accumulated in the main exhaust pipe 11 as a drain. Considering the case where the drain fills the horizontal part 15 of the main exhaust pipe and the device operates, the drain must push up the vertical part 16 of the main exhaust pipe by the air pressure in the foreskin.

일반적으로 주배기관의 수평부의 길이는 수직부의 길이 H'보다 길고, 또 H'>H이므로 전술한 바와 같이 수봉관(3)에 의한 안전장치가 작동할때에는 포피(7)내의 내압이 허용설계압력 이상으로 되는 결점이 있었다. 또 내압검지관(12)에도 이같이 드레인이 고여 별도 설치한 드레인 제거 밸브에 의하여 드레인을 빼지 않으면 내압검지용 압력계(4)가 정상으로 작동하지 않는 결점이 있었다. 상기와 같은 결점을 해결한 것이 본 발명이다.In general, the length of the horizontal portion of the main exhaust pipe is longer than the length H 'of the vertical portion, and H'> H. Therefore, when the safety device is operated by the water sealing tube 3 as described above, the internal pressure in the foreskin 7 is the allowable design pressure. There was a fault which became ideal. In addition, the pressure detecting pipe 12 also has a drawback in that the pressure detecting pressure gauge 4 does not operate normally unless the drain is removed by a drain removal valve separately provided with a drain. The present invention solves the above drawbacks.

이하 예시도면을 참조하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 제언(둑)을 제2도에 표시하고 있다. 제1도와 동일한 부호는 동일부위를 표시하고 있다.The suggestion of the present invention is shown in FIG. The same reference numerals as in FIG. 1 indicate the same parts.

그런데 본 발명의 제언은 제1도에 표시한 종래의 제언과 하기 점이 다르다. 즉 내압검지관(12)는 법부콘크리이트(8)에 상대하는 포피(7)의 법부의 비교적 상단부로부터 취출하고 타단을 주배기관의 수직부분(16)에 연통시키고 있다.However, the suggestion of the present invention is different from the conventional suggestion shown in FIG. That is, the pressure-resistant detection tube 12 is taken out from the relatively upper end of the legal portion of the foreskin 7 facing the concrete concrete 8 and communicates with the other end to the vertical portion 16 of the main exhaust pipe.

또 본 발명에 있어서 상기한 주배기관의 수직부분(16)은 결코 엄밀한 의미의 수직부분은 아니고 경사방향의 부분을 포함하는 극히 넓은 의미로 수평방향으로부터의 직립부분을 의미하고 있다. 일반적으로 공기에 의하여 팽창된 제언의 용적이 팽창매체의 공기중에 있는 수분에 의해 생기는 드레인에 의하여 100% 채워질 수는 없는 것이다. 따라서 상기한 바와 같은 경우에는 내압검지관(12)를 드레인이 채운다는 것은 생각할 수 없다. 또 주배기관의 수평부(15)를 드레인이 충만해도 내압 검지기를 통하여 전술한 바와 같이 수봉관(3)에 의한 안전장치가 작동한다.In addition, in the present invention, the vertical portion 16 of the main exhaust pipe described above means an upright portion from the horizontal direction in an extremely broad meaning including a portion in an inclined direction rather than a vertical portion in an exact sense. In general, the volume of the proposal expanded by air cannot be 100% filled by the drain generated by the moisture in the air of the expansion medium. Therefore, it cannot be considered that the drain fills the pressure-resistant detection tube 12 in the case described above. In addition, even if the drain 15 fills the horizontal portion 15 of the main exhaust pipe, the safety device by the water sealing pipe 3 operates as described above through the internal pressure detector.

따라서 본 발명에 있어서는 전기한 2개의 종래의 문제점, 즉 첫째, 수봉관(3)에 의한 안정장치가 포피(7)내의 내압이 허용설계 압력이상인 때 작동한다. 둘째, 내압 검지용 압력계(4)가 정상으로 작동하지 않는다는 결점을 해결할 수 있다.Therefore, in the present invention, the two conventional problems described above, first, the stabilizer by the water sealing tube 3 operates when the internal pressure in the foreskin 7 is above the allowable design pressure. Second, it is possible to solve the drawback that the pressure gauge 4 for internal pressure detection does not operate normally.

또 내압검지관(12) 및 주배기관은 종래와 같이 통상적으로는 수평방향으로 연장하나(드레인이 도중에 체류하는 것을 방지하기 위하여) 이것은 물론 기능상으로는 제언측이 낮아도 좋으나, 드레인은 배기쉽게하기 위하여 수평이거나 또는 조작실이 낮은 것이 좋다.The pressure detection tube 12 and the main exhaust pipe normally extend in the horizontal direction as in the prior art (to prevent the drain from staying on the way). Or low operating room.
