Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an oil levee that does not disperse oil that has fallen from a domestic oil tank, and in particular, has a peripheral wall made of steel plate.

[0002]

[Prior art]

 Since the ordinance to attach oil barriers to domestic oil tanks (500 liters or more and less than 1000 liters) came into effect in the second year of the system, there is no conventional technology. Although the installation standards issued by the fire department differ slightly depending on the local government, it is generally said that the oil levee may be reinforced concrete or steel plate, and there is no regulation on its structure.

[0003]

[Problems to be solved by the device]

 This is a simple and leak-proof form of the part that supports an oil tank that is close to 1 ton when it is full, but supports it without fear of tilting, and the part that surrounds it in an oil-tight manner. The purpose is to develop oil barriers that can be used as manufacturing standards in the future.

[0004]

[Means for Solving the Problems]

 The oil barrier with steel plate surrounding walls of this invention is a steel plate surrounding wall that stands vertically with the lower part submerged in the site, a watertight concrete layer that fills the lower part of the inner space of the surrounding wall evenly, and the lower part It is characterized in that it is equipped with four bunk stones for oil tank placement, which are buried in the site, the upper part is surrounded by the concrete layer, and only the head is exposed.

[0005]

[Action]

 The oil barrier of this invention is made of steel plate only on the surrounding wall and a watertight concrete layer on the bottom. Therefore, the peripheral wall acts as a concrete pouring formwork. The concrete layer then fixes the four slabs. The boulders themselves bury the lower part on the site to support the weight of the tank.

[0006]

【Example】

 1 and 2 show an embodiment of this invention. 1 is a steel plate surrounding wall, 2 is a watertight concrete layer, 3 is a bund stone, 4 is an oil tank, 5 is its leg, 6 is its connecting beam, 7 is a streak, 8 is a tread, and 9 is a filler port. 10 is a ventilation pipe, 11 is a level gauge, 12 is an extraction valve with a strainer, 13 is a drain plate, 14 is a drain plug, 15 is a foundation bolt, and G is a site. Site G is filled with gravel in the required area and thickness, and the lower part of the surrounding wall 1 is sunk into it to stand vertically as shown in FIG. Before or after that, four slabs 3 are arranged so as to fit the legs 5 of the oil tank, and the lower part thereof is buried in the gravel.

Then, concrete 2 is poured using the peripheral wall 1 as an outer peripheral formwork, and is embedded so that only the upper part of the slab 1 is exposed.

When the concrete 2 is hardened, the surface and the boundary with the surrounding wall 1 are made watertight, so that mortar is poured, but the concrete is applied. Now that the oil barrier is completed, the treads 8 of the oil tank 4 are placed on the bundles 1. It is a well-known technique that the bundle stone 1 is a commercially available product, and that the foundation bolt 15 is exposed on the upper surface thereof and the tread plate 8 is tightened with the nut.

Although the steel plate surrounding wall 1 has a welded structure in the embodiment of FIG. 1, bolt and nut tightening is shown in FIGS. 3 and 4 in order to avoid distortion of the steel plate due to welding. The peripheral wall 1 is formed by connecting four steel plates 1a at four corners, and the connecting portions are, as shown in FIG. 4, sandwiched between the outer chevron steel 16 and the inner chevron steel 17, and the bolts 18 and nuts. It is tightened with 19 and uses plate packing 20 and washer-shaped packing 21 to make a water connection. In this example, only the inner chevron steel 17 has a length that greatly penetrates into the site G to strengthen the connection between the site G and the peripheral wall 1.

Although one embodiment has been described above, it goes without saying that the embodiment of the present invention is not limited to the above embodiment.

[0011]

[Effect of device]

 The oil levee of the present invention controls the lateral movement of the surrounding wall by sinking the lower part of the steel plate surrounding wall on the site, and each bundle stone with the legs of the oil tank fixed is buried in the site. Therefore, it supports the weight of the tank stably. The concrete layer placed inside the surrounding wall spreads out flatly using the surrounding wall as a formwork, fixing the four slabs to the required positions, and the waterproof mortar layer etc. prevents oil from leaking from the dike floor. It becomes a face. By using a concrete layer instead of steel plate for the floor, it became easy to construct the base of the pile of heavy stones on the premises and the head on which the tank was placed above the floor.
