Description

Underground Oil Storage Tanks {THE SUBTERRANEAN OIL STORAGE TANK}

The present invention relates to an oil storage tank for underground laying to prevent soil pollution.

In particular, the manufacturing process can be simplified, and the inspection rod and sensor can always operate.

So that it can be quickly recognized and confirmed in the event of a leak

The present invention relates to an oil storage tank for underground laying.

In general, the fuel to be used is

Oil storage tanks are embedded for storage.

In accordance with the Fire Protection Law (Art. 199),

There are two main categories. Firstly, the tank rooms are waterproof.

Among them, tanks with asphalt roofing are installed and leaked around them.

The detection pipe is installed to monitor the outflow of oil. The other is concrete

Double wall tanks are installed in open tank rooms with floor and column ceilings.

Leak detection pipes should be installed between the double walls to detect oil leakage from the tank.

How to install

In the former case, the construction of a concrete bulkhead is expensive and time-consuming

Over time, wall cracks occur and oil leaks are not detected.

If the water penetrates into the upper crack of the wall,

As water cannot flow to the outside, the water accumulates and the corrosion of the tank is promoted.

If you have a gas station selling mixed oil,

Cases also had adverse effects

The latter case is disclosed in US Patent Publication No. 4672366 and improved domestically.

US Patent Publication No. 2001-0009905 can be described as an example.

In the case of heading 4672366, there is a device that can be checked directly by an inspector.

There is no domestic application because it does not comply with domestic fire law standards.

On the other hand, in the case of domestic published patent 2001-0009905, leaks through the tank body

Formation of the detection tube makes the manufacturing process difficult and the fabric used in the US Patent Publication

By constructing the buffer part using the mesh to collect the leaked oil

U.S. patent because this buffer is thin and the thickness of tank is impossible to maintain

In the case of the publication, the sensor is detected using a sensor, so even if the buffer part is thin, a small amount of oil

It is possible to detect, but the detection rod through the inspection rod specified in the national fire law

For early detection, the leaked oil is collected in one place and quickly

It is most preferable to form and check through the inspection rods.

Unable to maintain a special depth, the leaked oil may

If not, there is a problem that can not be checked.

The present invention is to solve the conventional problems as described above

Its purpose is to simplify the process of creating unnecessary tanks, thereby reducing costs

Occasional inspection system is established through the establishment of a regular alarm system through sensors and an inspector.
