지하 콘크리트 구조물 부력 조절장치 {Buoyant controller of underground concrete structure}Buoyant controller of underground concrete structure

본 발명은 건물의 지하 주차장 등 지하 콘크리트 구조물 외부의 지하수에 의해 구조물이 부력을 받게 되어 콘크리트 구조물에 균열이 발생하거나 누수가 되는 것을 방지하기 위한 부력 조절장치에 관한 것이다. The present invention relates to a buoyancy control device to prevent the structure is buoyant by the groundwater outside the underground concrete structure, such as underground parking lot of the building to prevent cracking or leakage of the concrete structure.

일반적으로 지하 콘크리트 구조물에는 구조물의 자중과 지하수에 의한 부력이 동시에 작용하는데, 지하수의 수압이 상승함에 따라 부력이 구조물의 자중보다 크게 될 경우 구조물에 변형이 일어나 큰 손상을 입게 된다.In general, the self-weight of the structure and buoyancy due to the groundwater act simultaneously on the underground concrete structure. If the buoyancy is greater than the self-weight of the structure as the water pressure of the groundwater rises, the structure is deformed, causing great damage.

종래에 이 부력에 의한 손상을 방지하기 위한 경제적인 방법으로 배수공법이 채택되기도 하였다. 종래의 배수공법은 구조물의 바닥 아래에 유공관과 집수정을 설치 하여 지하수를 유입시키고 이를 외부로 배출시켜 지하수에 의한 부력이 발생치 않도록 하였다. 이 경우 집수정의 지하수를 외부로 배출시키기 위한 펌프가 지속적으로 가동되어 전력소모가 많은 단점이 있어, 대한민국 등록특허공보 제10-0443640호에서는 연직배수관 등을 설치하여 평상시의 자연수위 상태에서는 지하수 배출이 되지 아니하나 우기시 지하수위의 높이가 특정 높이까지 높아질 때만 자연적으로 지하수가 월류하게 하도록 개시하였다. 또한 등록특허공보 제10-059421호에서는 목표 지하수위 이상 수압이 작용한 경우 유입관내의 수프링이 압축되어 배수가 되도록 설계하였으나 탄성스프링의 특성상 유입구의 개방이 용이하지 못하여 장마철과 같은 우기시 급격한 지하수위 상승에 따른 부력증가시 다량의 배수가 불가능한 단점이 있다.Conventionally, the drainage method has been adopted as an economical method for preventing damage caused by buoyancy. In the conventional drainage method, a perforated pipe and a water collecting well are installed under the bottom of the structure to introduce groundwater and discharge it to the outside to prevent buoyancy caused by groundwater. In this case, the pump for discharging the groundwater of the sump to the outside continuously operates, there is a drawback of a lot of power consumption, in the Republic of Korea Patent Publication No. 10-0443640 installed vertical drainage pipes, such as groundwater discharge in the normal natural water level Although this is not the case, when the rainy season when the groundwater level is raised to a certain height, the groundwater naturally started to overflow. In addition, Patent Publication No. 10-059421 is designed so that the water spring in the inlet pipe is compressed and drained when the water pressure above the target ground water level acts, but due to the nature of the elastic spring it is not easy to open the inlet opening, so sudden groundwater during the rainy season like rainy season When buoyancy increases due to the above rise, a large amount of drainage is impossible.

상기 연직배수관을 이용한 배수시스템은 지하 건축물 바닥 상부로 배관을 설치해야 하므로 미관상 좋지 못하고 차량의 주차나 물건의 효율적인 적하가 곤란하며, 특히 건축물 완공 후 부력에 의한 변형이 관찰되거나 위험이 예견되어 보수보강을 실시해야 하는 경우에는 연직배수관을 기존 지하 공간에 장애물이 되지 않도록 시공하기 어려운 단점이 있었다. 본 발명은 연직배수관이 가지고 있는 이러한 문제를 해결하기 위하여 연직배수관 대신에 지면 아래에 설치하게 되는 부력조절장치를 제시하여 지하 건축물의 바닥 위에 노출되지 않고도 적절한 임계수압에 도달하였을 때 지하수가 단시간에 배출될 수 있도록 한 것이다.In the drainage system using the vertical drainage pipe, pipes should be installed above the floor of the underground building, which is not good in appearance, and it is difficult to efficiently drop the parking or the object of the vehicle.In particular, after the completion of the building, deformation due to buoyancy is observed or danger is predicted. When it was necessary to perform the vertical drain pipe was difficult to construct so as not to obstruct the existing underground space. The present invention proposes a buoyancy control device to be installed below the ground instead of the vertical drainage pipe to solve this problem of the vertical drainage pipe to discharge the groundwater in a short time when the appropriate critical water pressure is reached without being exposed on the floor of the underground building. It would be possible.

It can be a material such as metal or plastic, and if the fixing pin is broken, the valve will open temporarily to release the groundwater and release the water pressure, and if the fixing pin is broken, It can be installed by adding a protective cap on the top to prevent people from being injured or damaging objects. Characterized the adapted so that ground water is almost bursting pressure is released once again possible to close the valve restored by inserting the fixing pin.

본 발명은 건물의 지하 주차장 등 지하 콘크리트 구조물 외부의 지하수에 의해 구조물이 부력을 받게 되었을때 수압이 일정간 임계값이 되면 노치형상의 고정핀이 부러짐으로써 지하수가 분출되어 콘크리트 구조물에 균열이 발생하거나 누수가 되 는 것을 방지할 수 있도록 한 것이다. 또한 종래의 배수 시설에 비하여 지하 건축물의 바닥에 노출되지 않고도 적절한 임계수압에 도달하였을 때 지하수가 단시간에 배출 될 수 있도록 한 것이다.According to the present invention, when the structure is buoyant by groundwater outside the underground concrete structure, such as an underground parking lot of a building, when the water pressure reaches a predetermined threshold, the groundwater is ejected by breaking the fixing pin in a notch shape, and cracking occurs in the concrete structure. This is to prevent leakage. In addition, the groundwater can be discharged in a short time when the appropriate critical water pressure is reached without being exposed to the floor of the underground building compared to the conventional drainage facility.
