Abstract

The present invention relates to a discharge unit capable of detecting a water leak in a polyethylene (PE) lining concrete water tank, and a construction method thereof. According to the present invention, drain water such as leachate flowing inside the concrete water tank condensates between the concrete water tank and a PE sheet, and water leaked due to damage of the PE sheet is staged in a water collection well of the concrete water tank to be overflowed to a drain pipe along a vertical drain pipe without a separate power source. As such, since the drain water is drained outside the concrete water tank, corrosion of the concrete water tank and blistering of the PE sheet are prevented; thereby being able to extend the lifetime of the product. Moreover, a cover installed in the vertical drain pipe is separated to make sediment inside the vertical drain pipe cleaned when the inside of the concrete water tank is cleaned such that smooth drainage of the drain water is induced; thereby being able to facilitate maintenance. When a water level of the drain water drained outside the concrete water tank is detected in the water collection well by a water level sensor, a leak state in accordance with the damage of the PE sheet is able to be detected by an alarm sound through an alarm member; thereby maximizing reduction in damage due to the water leak by actively coping with the water leak, thus enhancing economic effect.

Description

Technical Field [0001] The present invention relates to an exhaust unit capable of detecting leakage of a PE lining concrete water tank,

The present invention relates to a PE lining concrete water tank, and more particularly, to a PE lining concrete water tank, which is capable of reducing the number of condensation water flowing between a concrete water tank and a PE sheet, PE lining that can detect the leakage of water due to damage to the PE sheet when the discharge water discharged to the discharge pipe is above a certain level, as well as to discharge overflow to the discharge pipe, And a construction method thereof.

In general, the water tank is used to store a certain amount of water and supply it to buildings with a lot of domestic water such as residential apartments and business buildings. The water tank may be a stainless steel panel tank, an SMC panel tank, an FRP tank, .

The concrete water tank is formed by forming a mold with a form in which a reinforcing bar is laid to form a water tank of a predetermined shape and injecting and curing concrete inside the mold with a discharge pipe connected to one side thereof, It can be used hygienically while preventing direct contact between the concrete wall and the water that is dewatered into the seat.

However, the condensation caused by the temperature difference between the water and the outside air that is being dumped into the concrete water tank and the leakage water leaking into the damaged waterproof sheet are concentrated on the bottom surface of the concrete water tank and the waterproof sheet is detached from the concrete wall. The water tank is easily corroded, resulting in poor durability and shortened service life.

In order to solve the above problems, the inventor of the present invention has registered a waterproof structure of a concrete water tank using a polyethylene sheet in Korean Patent No. 10-0431533.

The prior art patent has solved the conventional problem by discharging the leakage water leaking from the condensation and damaged waterproof sheet to the outside of the concrete water tank through the drain hole formed in the same line with the bottom surface of the concrete water tank, Or condensation such as residue is deposited to close the drain hole, so that it is difficult to smoothly discharge condensation and water leakage. Also, the waterproof sheet is detached from the concrete wall due to dew condensation and leakage on the bottom surface of the concrete tank, and the concrete is corroded Which is a problem in the prior art in which durability is poor.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2006-0104456 discloses a concrete water tank waterproofing device.

The patent disclosed in the prior art can solve the conventional problem by discharging the water that has been collected by the pump to the outside of the concrete water tank through the piping by the operation of the pump. However, since the piping is formed so as to protrude to the upper part of the concrete water tank, There was a problem not to.

In addition, when the supply of the power is stopped, the water remaining in the collection tank can not be discharged to the outside of the concrete tank by the operation of a separate pump. However, It is not only damaged due to leaking water, condensation and leakage from the concrete wall due to leakage of waterproof sheet due to leaking water, leakage of durability due to corrosion of concrete, and accumulation of sediments inside the pipe. So that it is not possible to discharge the water to the outside.
