방수시스템 성능 실험장치{Waterproof system performance test device}Waterproof system performance test device

본 발명은 방수층에 수압을 가하여 방수성능을 평가하는 방수시스템 성능 실험장치에 관한 것으로, 더욱 상세하게는 시험하는 방수층에 다양한 변형과 화학적 환경 및 진동하중 등을 가하여 방수 성능을 평가할 수 있는 방수시스템 성능 실험장치에 관한 것이다.The present invention relates to a waterproof system performance test apparatus for evaluating waterproof performance by applying water pressure to a waterproof layer, and more particularly, to a waterproof system performance test apparatus capable of evaluating a waterproof performance by applying various deformation, chemical environment, and vibration load to the waterproof layer to be tested To an experimental apparatus.

통상적으로 방수층의 방수성능 시험방법은 방수막에 수압을 가할 수 있도록 물을 채워 시험하고 있는바, 그러나 종래 이러한 방수층 시험방법은 시험장치를 구성하기가 용이한 장점을 갖추고 있으나, 단지 물만 채워진 상태의 수압만을 이용하기 때문에 실험시 약한 수압으로 인하여 시험결과를 확인하기 위하여는 많은 시간이 소요되었다.In general, the waterproof performance test method of the waterproof layer is performed by filling the waterproof membrane with water so as to apply water pressure. However, the conventional waterproof layer test method has advantages that it is easy to constitute the test apparatus. However, Due to the use of water pressure only, it took a long time to confirm the test result due to the weak water pressure in the experiment.

따라서 건물의 옥상에 적용하는 옥상방수 내지는 얕은 지하에 매립하는 시설물밖에는 적용할 수 없는 단점을 지니고 있었다.Therefore, it has the disadvantage that it can not be applied only to the roof waterproofing applied to the roof of the building or the facilities buried in the shallow underground.

한편, 통상적인 방수층은 구조물의 거동에 따라 변형이 발생하며 변형 발생시 급격하게 방수 성능이 저하할 수 있으며, 방수층의 변형시 방수성능을 확인하기 위하여는 방수층에 변형을 가하는 동시에 수압을 가하여 방수성능을 시험하여야 한다.On the other hand, in a conventional waterproof layer, deformation occurs according to the behavior of the structure, and when the deformation occurs, the waterproof performance may deteriorate. In order to confirm the waterproof performance of the waterproof layer in deformation, the waterproof layer is deformed, It shall be tested.

또한 방수층에는 변형뿐만 아니라 화학적 환경 및 진동하중이 가하여 지므로 이러한 환경 하에서 수압을 가하며 방수성능을 평가하여야 하는 실정이다.In addition, the waterproof layer is subject to chemical environment and vibration load as well as deformation. Therefore, it is necessary to evaluate the waterproof performance by applying water pressure under such circumstances.

이에 본 발명은 상기와 같은 요구에 맞추어 발명된 것으로, 시험하는 방수층에 다양한 변형과 화학적 환경 및 진동하중 등을 가하여 방수성능을 평가할 수 있는 방수 시스템 성능 실험장치를 제공함에 그 목적이 있다.Accordingly, it is an object of the present invention to provide a waterproof system performance test apparatus capable of evaluating a waterproof performance by applying various deformation, chemical environment, and vibration load to a waterproof layer to be tested.

또한 환경조건에 따른 시험을 하기 위해 냉각라인(11)과 열선라인(10)을 상부챔버(3)내에 장착하고, 수압 변동에 의한 방수성능을 평가하기 위해 압력센서(15)를 설치한다.A cooling line 11 and a hot line 10 are installed in the upper chamber 3 for testing according to environmental conditions and a pressure sensor 15 is installed for evaluating the waterproof performance by the fluctuation of water pressure.

통상적으로 전력구 등 지하 시설물의 상시 수압이 걸리는 부위의 콘크리트부에 균열이 발생하고, 수위의 발생 및 온도, 차량의 진동에 의한 하중으로 균열부에 변형이 발생되면 콘크리트에 부착된 방수층에 손상이 발생한다. Generally, if cracks occur in the concrete part of the underground facility where the water pressure is constantly applied in the underground facilities such as electric power, and the deformation occurs in the cracked part due to the generation of the water level and the temperature and vibration of the vehicle, damage to the waterproof layer adhered to the concrete Occurs.
