본 발명은 우물통용 가물막이 구조에 관한 것으로 더 상세하게는 수위변화에 따라 높이를 조절할 수 있고, 그 설치와 해체가 용이하도록 발명된 것이다.The present invention relates to the structure of the faucet membrane for a well bucket, and more particularly, the height can be adjusted according to the water level change, and the invention is invented to facilitate installation and dismantling.

일반적으로 강이나 호수에서의 교량 건설은 우물통을 수면 아래, 즉, 수중에 설치하고 그 내부에 콘크리트 타설 양생하여 교각을 형성한 후 이 교각의 상부로 슬라브가 설치되어 교량이 완성되는 것이다.In general, the construction of bridges in rivers or lakes is to install wells under the water surface, that is, in the water, and to pour concrete into them to form bridges, and then the slabs are installed on top of the bridges to complete the bridges.

이 우물통은 콘크리트를 타설하여 소정 두께를 가지는 원통형상으로 제조되며, 하단부를 수중의 지면에 소정의 깊이로 침하시켜 수중에 설치된다.The well is made into a cylindrical shape having a predetermined thickness by pouring concrete, and the lower end is settled to the ground in the water to a predetermined depth and is installed in the water.

상기 우물통은 내부에 물이 없는 상태로 수중에 설치되어 내부로 콘크리트를 타설 양생하여 우물통 기초를 형성하는 것이다.The well is installed in the water in the absence of water therein to pour concrete into the interior to form a well basin.

상기 우물통은 통상 교량이 건설되는 하천의 평균 수위에 대응되는 높이로 시공되며, 교각의 높이는 하천의 최고 수위보다 높게 설계되어 시공되고 있는 실정이다.The well is usually constructed at a height corresponding to the average level of the river in which the bridge is constructed, the height of the bridge is designed to be higher than the highest level of the river is being constructed.

즉, 교각은 상기 우물통의 내부에 콘크리트르 타설하여 우물통 기초를 형성한 후 이 우물통 기초의 상부로 하천의 최고 수위보다 높은 높이를 가지도록 콘크리트를 타설하여 양생시켜 시공되는 것이다.That is, the pier is to be constructed by pouring concrete to the inside of the well to form a well base, and then cast concrete to have a height higher than the highest level of the river to the top of the well base.

따라서 우물통의 상부에는 우물통 내부로 하천의 물이 유입되어 교각 시공에 방해가 되지 않도록 하천의 최고 수위보다 높은 높이를 가지는 가물막이를 설치하고 있다.Therefore, in the upper part of the well is installed a temporary barrier having a height higher than the highest level of the river so that the water flows into the well to prevent the bridge construction.

도 1에서 도시한 바와 같이 종래의 가물막이(2)는 우물통(1)의 상부면에 안착되는 금속재의 베이스플레이트(2a)의 상부로 일정높이로 세워지는 금속차단판(2b)으로 이루어진다.As shown in FIG. 1, the conventional temporary sealer 2 includes a metal blocking plate 2b that is erected at a predetermined height to an upper portion of the base plate 2a of the metal seated on the upper surface of the well 1.

상기 금속차단판(2b)은 우물통(1)의 높이와 하천의 최고 수위의 차이 이상의 높이로 제조되어 하천이 최고 수위로 만조되었을 경우 우물통(1) 내부로 물이 유입되는 것을 방지하는 것이다.The metal blocking plate 2b is manufactured at a height greater than or equal to the difference between the height of the well 1 and the highest water level of the river to prevent water from flowing into the well 1 when the river is high at the highest water level. .

그리고 베이스플레이트(2a) 하부에는 러버패널(3)이 구비되어 우물통(1)의 상부면에 안착 시 가물막이와 우물통(1) 사이의 연결 틈새를 실링시킨다.And a rubber panel (3) is provided at the bottom of the base plate (2a) to seal the connecting gap between the cloister and the well (1) when seated on the upper surface of the well (1).

이 가물막이(2)는 베이스플레이트(2a) 내, 외측에 구비되는 고정고리(4)와 우물통(1)의 몸체에 고정되는 철근(5)을 턴버클(6)을 통해 연결하여 장착 고정되는 것이다.The temporary barrier 2 is fixed by connecting the fixing ring 4 provided on the outside of the base plate 2a and the reinforcing bar 5 fixed to the body of the well 1 through the turnbuckle 6. will be.

그러나 상기한 종래의 가물막이는 베이스플레이트의 상부로 일정높이로 세워지는 금속차단판으로 이루어져 시공 중 하천이 최고 수위로 만조되지 않은 경우에도 하천의 최고 수위 이상의 높이를 가져야 하고, 단판의 금속판의 경우 수압에 견디지 못하므로 복수의 수평보강재 및 수직 보강재를 덧붙여 제조해야 함으로 그 제조비용이 비싼 문제점이 있었던 것이다.However, the above-mentioned conventional temporary curtain is made of a metal blocking plate that is erected to a certain height above the base plate and should have a height higher than the maximum water level of the river even when the river is not tidal at the highest water level during construction, Since it does not endure water pressure, a plurality of horizontal reinforcing materials and vertical reinforcing materials had to be added to the manufacturing cost, which had a problem of being expensive.

또한 종래의 가물막이는 베이스플레이트를 러버패널로 실링시킨 상태로 우물통몸체에 고정 설치하나, 금속차단판의 높이와 추가되는 수평, 수직 보강재에 따라 전체 하중이 변경되므로 러버패널이 이 하중을 견디지 못해 뒤틀리거나 파손되어 그 틈새로 하천의 물이 우물통 내부로 유입되는 문제점이 있었던 것이다.In addition, the conventional clamshell is fixedly installed in the well body with the base plate sealed with a rubber panel, but the rubber panel does not withstand this load because the overall load changes depending on the height of the metal blocking plate and the horizontal and vertical reinforcement added. There was a problem that the water flows into the well into the gap as it is not twisted or broken.

또 종래의 가물막이는 우물통에 턴버클을 사용하여 장착 고정되므로 그 설치와 해체가 복잡한 문제점이 있었던 것이다.In addition, since the conventional clamshell is mounted and fixed using a turnbuckle in the well, the installation and dismantling were complicated problems.

그리고 종래의 가물막이는 일정높이를 가지므로 하천이 기상이변으로 최고 수위보다 높게 올라갈 경우 그 상부로 별도의 가물막이를 설치해야 하나 이는 사실상 불가능하여 집중 호우에 따른 하천 수위의 급변화에 대처할 수 없는 폐단이 있었던 것이다.And since the conventional barrier has a certain height, if the river rises higher than the highest water level due to extreme weather, a separate barrier should be installed at the upper part, but it is impossible to cope with the sudden change of the river level due to the heavy rain. There was a dissolution.

본 발명의 목적은 가물막이를 우물통의 상부면에 적층시켜 하천의 현재 수위에 따라 높이 조절이 가능하고 그 조립, 분해가 간단하여 수위의 급변화 시에 대처가 용이하고 교각 시공을 안정적으로 할 수 있도록 하는 우물통용 가물막이 구조를 제공하는 데 있다.The object of the present invention is to stack the clam on the upper surface of the well can be adjusted in height according to the current water level of the river and its assembly, disassembly is easy to cope with the sudden change in the water level and to make the pier construction stable It is to provide a structure for the faucet screen for the well.

이러한 본 발명의 목적은 상, 하부가 관통된 통형상으로 수중에 설치되는 우물통과, 상기 우물통의 상부로 설치되어 우물통 내부로 하천의 물이 유입되는 것을 차단하는 가물막이를 포함한 우물통용 가물막이 구조에 있어서,The object of the present invention is a well bucket installed in the water in the upper and lower through the cylindrical shape, and a well bucket for the well including a water barrier installed to the upper portion of the well to block the flow of river water into the well In the structure of the membrane,

상기 가물막이는 우물통의 상부에 안착되며 그 상부로 다수개 적층되는 적층물막이부재와, 상기 적층물막이부재의 결합면에 구비되는 실링부재와, 상기 적층물막이부재를 각각 결합시키는 결합부재를 포함하여 달성된다.The temporary closure is seated on the upper part of the well and stacked on top of the stack member, a sealing member provided on the coupling surface of the laminate member, and the coupling member for coupling the laminate member, respectively; Is achieved.

즉, 상기 적층물막이부재는 우물통의 상부로 결합부재로 결합되면서 교각이 시공되는 하천의 현재 수위에 맞게 적층되어 우물통 내부로 하천의 물이 유입되는 것을 차단하는 것이다.That is, the stacking member is coupled to the coupling member to the upper part of the well and is stacked in accordance with the current level of the river where the pier is constructed to block the flow of river water into the well.

본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

도 2 는 본 발명인 가물막이를 도시한 사시도로서, 원통형상으로 형성된 적층물막이부재의 형상을 나타내고 있다.Fig. 2 is a perspective view showing the temporary closure of the present invention, showing the shape of the laminated closure member formed in a cylindrical shape.

도 3은 본 발명의 사용 상태 단면도로서, 우물통의 상부로 적층물막이부재가 적층되어 결합된 상태를 나타내고 있다.3 is a cross-sectional view illustrating a state of use of the present invention, in which a stack member is stacked and bonded to an upper portion of a well bucket.

이하, 도 2에서 도시한 바와 같이 본 발명인 가물막이(2)의 적층물막이부재(10)는 우물통(1)의 형상에 대응되는 형상으로 형성되며, 통상적으로 우물통(1)의 형상이 원통형상이므로, 소정의 폭과 높이를 가지는 원통형상으로 형성되고 그 직경과 폭은 사용되는 우물통(1)에 따라 결정됨을 밝혀둔다.Hereinafter, as shown in FIG. 2, the laminate blocking member 10 of the temporary sealer 2 of the present invention is formed in a shape corresponding to the shape of the well bucket 1, and the shape of the well bucket 1 is generally cylindrical. Since it is a phase, it turns out that it is formed in the cylindrical shape which has a predetermined | prescribed width and height, and the diameter and width are determined according to the well 1 used.

이 적층물막이부재(10)는 철근 콘크리트재로 제조되는 것을 기본으로 하며, 이 외 수압에 견디고 적층 후 일정 하중으로 결합될 수 있는 어떠한 재질도 사용이 가능함을 밝혀둔다.The laminate member 10 is based on being made of reinforced concrete, and it is noted that any material that can withstand water pressure and can be combined with a constant load after lamination can be used.

또 적층물막이부재(10)는 각각의 높이를 일정하게 제조하여 하나의 거푸집으로 동일한 형상의 것을 다 수개 제조하도록 함으로써 제조원가를 절감하고, 높이를 규격화할 수도 있다.In addition, the laminated film blocking member 10 may be manufactured to have a constant height to manufacture a plurality of the same shape in one formwork to reduce the manufacturing cost, and can also standardize the height.

또한 적층물막이부재(10)는 각각의 높이를 다르게 제조하여 적층되는 개수뿐만 아니라 적층되는 적층물막이부재(10)의 높이에 따라 우물통(1)의 상부로 설치되는 가물막이(2)의 높이를 조절할 수 있도록 할 수도 있다.In addition, the stacking member 10 has a height of the temporary shield 2 installed above the well 1 according to the height of the stacked stacking member 10 as well as the number of stacking by manufacturing each height differently. You can also make adjustments.

이는 현재 하천의 수위에 따라 적당한 높이의 적층물막이부재(10)를 선택적으로 적층시킬 수 있어 가물막이(2)의 높이 조절 시 자유도를 높일 수 있는 효과가 있는 것이다.This can selectively stack the laminated film member 10 of a suitable height according to the current level of the river has the effect of increasing the degree of freedom when adjusting the height of the temporary film (2).

한편, 상기 적층물막이부재(10)는 상, 하부 결합면에 각각의 적층물막이부재(10)를 결합시키는 결합부재(20)가 구비된다.On the other hand, the laminate blocking member 10 is provided with a coupling member 20 for coupling the respective laminate blocking member 10 to the upper, lower coupling surface.

상기 결합부재(20)는 상기 적층물막이부재(10)의 하부면에 간격을 두고 다수개 돌출되는 결합돌기(21)와, 상기 적층물막이부재(10)의 상부면에 상기 결합돌 기(21)가 결합하도록 형성된 결합홈(22)을 포함한다.The coupling member 20 includes a plurality of coupling protrusions 21 protruding at a lower surface of the laminate blocking member 10 and the coupling protrusion 21 on an upper surface of the laminate blocking member 10. It includes a coupling groove 22 formed to couple.

즉, 상기 결합돌기(21)는 적층물막이부재(10)가 다수로 적층될 경우 하부에 위치하는 적층물막이부재(10)의 결합홈(22)으로 삽입되면서 결합하여 적층물막이부재(10)가 적층된 상태에서 하천의 흐름에 의해 밀려 분리되는 것을 방지하는 것이다.That is, the coupling protrusion 21 is inserted into the coupling groove 22 of the laminate blocking member 10 positioned below when the laminate blocking member 10 is stacked in a plurality, and thus, the laminate blocking member 10 is laminated. It is to prevent being separated by being pushed by the stream in the state.

또 적층물막이부재(10)는 결합돌기(21)가 결합홈(22)으로 삽입되어 결합하면서 적층되므로 적층 후 별도의 결합작업이 요구되지 않고 설치와 분리가 용이한 것이다.In addition, since the stacking member 10 is laminated while the coupling protrusion 21 is inserted into and coupled to the coupling groove 22, it is easy to install and separate without requiring a separate coupling operation after the stacking.

상기 결합부재(20)는 상기한 이외에 적층물막이부재(10)를 적층한 후 결합시켜 수평방향의 횡력에 지지되는 어떠한 구조도 본 발명에 포함됨을 밝혀둔다.The coupling member 20 is also included in the present invention any structure that is supported by the lateral force in the horizontal direction by laminating the laminated film member 10 in addition to the above described.

한편, 상기 적층물막이부재(10)는 상부면 또는 하부면에 적층물막이부재(10)의 적층 시 결합면의 틈새를 실링하는 실링부재(30)가 구비된다.On the other hand, the laminate member 10 is provided with a sealing member 30 for sealing the gap of the coupling surface when the laminate member 10 is laminated on the upper surface or the lower surface.

이 실링부재(30)는 물과 접촉 시 팽창하는 수팽창 지수제를 사용하는 것을 기본으로 하고 이외 적층되는 적층물막이부재(10)의 틈새 사이를 실링하여 적층물막이부재(10)의 내부로 물이 침투되는 것을 방지하는 어떠한 것도 사용이 가능함을 밝혀둔다.The sealing member 30 is based on the use of a water-expansion index agent that expands upon contact with water, and seals between the gaps of the laminated film blocking member 10 to be laminated. Note that anything that prevents penetration can be used.

이 수팽창지수제는 적층물막이부재(10)의 하부면에 소정의 두께로 층을 형성하여 장착된다.This water-expandable index agent is mounted on the lower surface of the laminated body member 10 by forming a layer with a predetermined thickness.

상기 수팽창 지수제는 물과 접촉될 때 이온 이동이 발생되어 침투압 및 밀도가 감소되는 특성뿐만 아니라, 물을 흡수하면 이온들 간의 배척에 의해 용적이 수 내지 수십 배로 팽창하고 건조된 후에는 원래의 상태로 회복하는 성질을 갖는다. The water-expandable index agent not only has a property of generating ion migration when it comes in contact with water, thereby reducing the penetration pressure and density, but also absorbing water causes the volume to expand to several to several tens of times by rejection between ions, and then, after drying, Has the property of recovering to a state.

이와 같이, 수팽창지수제는 하천의 물과 접촉하면 물을 흡수하면서 용적이 팽창하여 적층된 적층물막이부재(10)의 틈새로 완전히 충전되어 하천의 물이 적층물막이부재(10)의 내부로 침투되는 것을 방지하는 것이다.As described above, the water-expandable index agent absorbs the water when it comes into contact with the water in the river, and expands in volume to completely fill the gap between the stacked laminate members 10, so that the water in the stream penetrates into the laminated membrane member 10. To prevent it.

또 상기 적층물막이부재(10)는 이송용 고리부(40)를 구비하여 기중기의 후크와 용이하게 연결할 수 있도록 한다.In addition, the laminate member 10 is provided with a hook 40 for transporting so that it can be easily connected to the hook of the crane.

상기 적층물막이부재(10)는 철근 콘크리트 재질로 이루어져 무게가 무거워 기중기로 들어올려 차례로 적층시켜야 하므로 기중기의 후크와 연결되어 그 이송과 설치가 용이하도록 하는 이송용 고리부(40)를 구비하는 것이다. Since the stacking member 10 is made of reinforced concrete, the weight is heavy and must be lifted by the crane in order to be stacked in order to be provided with a hook portion 40 for connecting with the hook of the crane to facilitate its transfer and installation.

이 이송용 고리부(40)는 적층물막이부재(10)의 내측면에 서로 대향되도록 2개가 설치되어 적층물막이부재(10)가 수평을 유지하면서 이송, 설치할 수 있도록 한다.The transfer ring 40 is installed on the inner surface of the laminate member 10 so as to face each other so that the laminate member 10 can be transported and installed while maintaining the horizontal.

상기 본 발명의 실시 상태를 상세히 설명하면 다음과 같다.Referring to the embodiment of the present invention in detail as follows.

우물통(1)의 상부면에는 상기 적층물막이부재(10)의 결합돌기(21)가 삽입되는 결합홈(22)이 형성되며 이 상부면으로 적층물막이부재(10)가 올려져 적층된다.A coupling groove 22 into which the coupling protrusion 21 of the laminate blocking member 10 is inserted is formed on the upper surface of the well 1, and the laminate blocking member 10 is lifted and stacked on the upper surface.

적층물막이부재(10)는 기중기로 들어 올려져 이송된 후 우물통(1)의 상부면으로 차례로 적층되고, 적층과 동시에 결합돌기(21)가 결합홈(22)에 결합하여 고정되는 것이다.After the stacking member 10 is lifted and lifted by a crane, the stacking member 10 is sequentially stacked on the upper surface of the well 1, and at the same time, the coupling protrusion 21 is coupled to the coupling groove 22 and fixed.

이 적층물막이부재(10)는 하천의 현재 수위와, 기상 상태를 고려하여 적당한 높이를 가지는 개수로 적층된다.The laminate blocking member 10 is laminated in a number having a suitable height in consideration of the current water level in the river and the weather condition.

하천의 수위가 높아지면 상기 적층물막이부재(10)를 더 적층시켜 높이를 증대시키는 것이다.When the water level of the river is increased, the laminate film member 10 is further laminated to increase the height.

상기 적층물막이부재(10)는 교각 건설이 완료된 후에 분리되어 제거되며, 이 경우 적층된 적층물막이부재(10)를 기중기로 들어올리면 결합돌기(21)가 결합홈(22)에서 빠지면서 간단히 분리되는 것이다.The laminate blocking member 10 is separated and removed after completion of the bridge construction, in this case, when the laminated laminate blocking member 10 is lifted by a crane, the coupling protrusion 21 is simply separated from the coupling groove 22. .

상기한 본 발명의 구성에 의하면 교각 시공 중 우물통 내부로 물이 침투되는 것을 방지하는 가물막이가 적층물막이부재의 적층 구조로 이루어져 그 설치 및 분리가 용이하여 시공기간을 단축하고 시공 비용을 절감할 수 있는 효과가 있는 것이다.According to the configuration of the present invention described above is made of a laminated structure of the laminated membrane member member to prevent water from penetrating the inside of the well during the construction of the pier to facilitate the installation and separation of the construction period and to reduce the construction cost It can be effective.

또한 가물막이의 높이는 적층물막이부재의 적층 갯수로 조절됨으로 하천의 수위변화에 따라 적층물막이부재를 적층, 분리하여 하천의 수위가 급변할 경우 대처가 용이한 효과가 있는 것이다.In addition, since the height of the temporary barrier is controlled by the number of stacking members of the laminate, it is easy to cope with the change in the water level of the stream by stacking and separating the laminate members according to the change in the water level of the stream.
