Abstract

The present invention is a leakage preventing structure of the water tank drain pipe through, the main purpose of the present invention is to provide a structure for preventing the leakage of the drain pipe through the water tank of the inner surface is closed with a PE panel.

The present invention is installed by passing through the drain pipe 11 in the lower end of the inner wall of the water tank (1) with a PE panel, the inner part of the water tank (1) of the drain pipe (11) 10 cm from the inner wall surface The degree is tightly wound with an exponential rubber band (12), and the PE sheet (13) covers a portion where the exponential rubber band (12) and the drain pipe (11) meet with a wall, and the PE sheet on the drain pipe (11). (13) is fixed to the three metal bands (14), and the water tank drain pipe penetrating part consisting of a step of joining the portion where the drain pipe 11 covered with the PE sheet 13 meets the wall by hot air bonding. Leakage prevention structure.

With this design, it is possible to prevent leakage of the water pipe through part of the water tank whose inner surface is finished with PE panel.

Description

Water prevention structure of a drainpipe penetration part of a water tank}

The present invention relates to a leak prevention structure of the water tank drain pipe through.

Generally, buildings or facilities require the installation of a water tank. The water tank is constructed of FRP or reinforced concrete according to its size and use, and its shape also varies according to its use and installation place, such as cylindrical or hexahedron, and can be located in the rooftop or basement of a building or facility.

As it is a simple structure, the difficulty in construction is small but it contains water and also has a function to let water flow, so the consideration of leakage is an important part of the design. The most vulnerable part of the leak will be the inlet and the drainage part where water is injected, and the drainage part is extremely vulnerable because it is always submerged except when checking or cleaning the water tank.

In particular, when the inner surface of the water tank is closed by PE panel, it is not easy to connect the drain pipe and PE panel, but it is precisely installed.

The main object of the present invention is to provide a structure for preventing the leakage of the through-pipe drain portion of the water tank with the inner surface of the PE panel.

1 is a detailed cross-sectional view of the water tank drain pipe penetrating portion according to the present invention.

2 is a cross-sectional view of a water tank including a water tank drain pipe through part according to the present invention.

Figure 3 is a state of completion of construction according to the leak-proof structure of the water tank drain pipe penetrating portion according to the present invention.

1: water tank 2: PE panel

11: drain pipe 12: exponential rubber band

13: PE sheet 14: metal band

The present invention is a leak-proof structure of the water tank drain pipe penetrating portion, the inner surface of the water tank (1) is installed through the drain pipe 11 in the lower end of the wall closed by PE panel, the water tank (11) 1) The inner portion of the inner wall about 10cm tightly wound with a rubber band (12), cover the portion where the water rubber band (12) and the water pipe 11 meets the wall with a PE sheet (13), The portion covered with the PE sheet 13 on the drain pipe 11 is fixed with two metal bands 14, and a portion where the drain pipe 11 covered with the PE sheet 13 meets a wall by hot air bonding. Leakage prevention structure of the water tank drain pipe penetrating part is composed of a process.

The index rubber band 12 is a rubber band having a size of 2 cm in width and 5 mm in thickness and is a synthetic rubber having a property of expanding about 4 times when it comes into contact with water as a product called 'super thread'.

The PE sheet 13 is about 3 mm thick, and three metal bands 14 are about 2 cm wide.

The part where the drainage pipe 11 in the inner part of the water tank 1 meets the wall is constructed by the above method, and the drainage pipe 11 of the outer part of the water tank 1 is connected to the wall. The part where it meets is handled by general liquid waterproofing.

A tight leakage preventing portion is formed by the interaction of the rubber band 12, the PE sheet 13, and the metal band 14. That is, the exponential rubber band 12 tries to expand, and the PE sheet 13 and the metal band 14 act to tighten, thereby forming a tightly bonded portion to prevent leakage.

With this design, it is possible to prevent leakage of the water pipe through part of the water tank whose inner surface is finished with PE panel.
