[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a waterproof wall for a watertight test of a waterproof door for forming a test water tank facing the waterproof door and performing a watertight test of the waterproof door after assembly or maintenance of the waterproof door.
[0002]
[Prior art]
Conventionally, the waterproof door device installed at the entrance / exit is in the dark environment after installation work on site, irradiates the watertight part of the waterproof door with test light, and checks whether there is leakage of the test light, This confirmed the watertight state.
[0003]
[Problems to be solved by the invention]
However, when damping overflowed water, the water flow and water pressure are directly applied to the waterproof door, so the conventional test environment is different from the actual use environment, so there is a problem that the reliability of the watertight performance is low. there were.
[0004]
An object of the present invention is to solve the above-described problems and provide a watertight test water blocking wall for a waterproof door capable of performing a highly accurate watertight test in a state close to a use environment.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention described in claim 1 is a watertight test water-stop test for a waterproof door that is installed facing the waterproof door and forms a test water tank between the waterproof door and a watertight test of the waterproof door. A plurality of wall blocks which are close to and away from each other; an elastic seal material interposed between the wall block and the floor wall and side wall of the entrance / exit; and the wall block is pressed against the floor wall and the side wall, respectively. A pressure member that compresses the elastic sealing material, a water stop sheet that covers the test water tank side of the plurality of wall blocks, and a support member that supports the wall blocks.
[0006]
According to the above configuration, even in a waterproof door that is not scheduled for a watertight test, the wall block is pressed against the floor wall and the side wall by the pressure member to compress the elastic sealing material, and the water blocking wall and the floor wall are compressed. A watertight test is planned by sealing the gap with the side wall well, preventing water leakage from the water stop door with a water stop sheet covering the entire surface of the water stop wall, and supporting the water stop wall with a support member. Even if it is a waterproof door that has not been installed, a water stop door can be installed on the water stop surface side of the waterproof door to form a test water tank, and a watertight test of the waterproof door can be carried out with high accuracy.
[0007]
The invention described in claim 2 is a waterproof wall for a watertight test of a waterproof door that is installed opposite to the waterproof door and forms a test water tank between the waterproof door and performs a watertight test of the waterproof door. An intermediate wall block disposed at an intermediate portion opposite to the intermediate wall block, a pair of left and right side wall blocks disposed on both sides of the intermediate wall block so as to be slidable in the width direction and in contact with the left and right side walls, A side pressurizing member disposed between the intermediate wall block and the side wall block and pressing the side wall block against the side wall, and a test water tank side of the intermediate wall block, the side wall block, and the side pressurizing member A waterproof sheet that covers the entire surface, a lower pressurizing member that presses the intermediate wall block and the side wall block against the floor wall, and supports the water pressure of the test water tank loaded on the intermediate wall block and the side wall block. A rear support member and the intermediate wall block; A sidewall block and is obtained by including an elastic sealing member interposed between the floor and side walls.
[0008]
According to the above configuration, the side pressure member is interposed between the intermediate wall block and the side wall block, and the water blocking wall is provided by the lower pressure member, even if the waterproof door is not scheduled for a watertight test. The elastic sealing material between the left and right side walls and the floor wall is compressed and sealed well, and water leakage from the water stop door that is expanded and contracted by a water stop sheet covering the entire surface of the water stop wall is prevented, and further testing is performed. Since the water pressure in the water tank can be supported by the rear support member, even a waterproof door that is not scheduled for a water-tight test can easily form a test water tank and perform a water-tight test on the waterproof door with high accuracy. .
