The utility model relates to a bury ground oil tank prevention of seepage pond drainage technique, especially a prevention of seepage pond drainage system, through building oil-proof sedimentation tank in the below ground, prevent seepage pond and drainage well in the side wall outside distribution of oil-proof sedimentation tank, make the automatic drainage well that flows in after oil-proof baffle and overflow launder of ponding in the prevention of seepage pond, discharge regional or garden drainage facility through the dive dredge pump, can effectively avoid preventing ponding in the seepage pond or in time discharge ponding, eliminate and bury hidden danger such as ground oil tank come-up, thereby guarantee the normal operating of relevant oil storage transport facility.
Background
The buried oil tank is a facility for storing fuel oil, and comprises an anti-seepage pool arranged below the ground, wherein a foundation base is arranged in the anti-seepage pool, an oil tank support and an anchoring part are arranged on the foundation base, the oil tank is fixed in the anti-seepage pool through the oil tank support and the anchoring part, sand is filled around the oil tank, and a manhole of the oil tank is communicated with the ground through an inspection well. Although the anti-seepage pool has functions of preventing the fuel oil stored in the oil tank from leaking and polluting the environment, preventing the electrochemical reaction from corroding the buried oil tank, and preventing the underground water from rusting the tank body, however, in the actual buried oil tank engineering, the water accumulation phenomenon possibly exists in the anti-seepage pool due to poor construction quality, the anti-seepage pool is equivalent to a large container, although the anti-seepage pool is filled with sand, the oil tank immersed in the water is stressed according to Archimedes' law and bears upward buoyancy, when the liquid level in the anti-seepage pool reaches a certain degree, the buoyancy borne by the oil tank is greater than the gravity and the pulling force of the anchoring piece, so that the oil tank with larger volume and lighter weight floats upwards (for example, when the oil tank is empty or the oil storage amount in the oil tank is less), the oil storage and transportation facilities are damaged, even the use of an oil supply system is interrupted, and other faults are caused, so that economic loss is generated, and the normal production operation of in-use business is influenced. For the empty oil tank without oil product, in order to prevent the oil tank from floating up, a method of injecting a hydraulic pressure tank can be adopted, but the method cannot solve the fundamental problem. Because the accumulated water exists in the anti-seepage pool, the water quantity in the oil tank is reduced, and the tank body still floats upwards when the buoyancy is larger than the reaction force. In addition, the method of filling water into the hydraulic tank involves the processes of filling water, draining water after the water is filled, drying the inner wall of the oil tank and the like, and requires certain capital, labor and equipment investment, thereby increasing the construction period. If an oil-separation sedimentation tank is constructed under the ground, an anti-seepage tank and a drainage well are distributed on the outer side of the side wall of the oil-separation sedimentation tank, so that accumulated water in the anti-seepage tank automatically flows into the oil-separation sedimentation tank, automatically flows into the drainage well after passing through an oil-separation baffle plate and an overflow groove, and is discharged into regional or park drainage facilities through a submersible sewage pump, the accumulated water in the anti-seepage tank can be effectively avoided or timely discharged, the hidden troubles of floating of a buried oil tank and the like are eliminated, and the normal operation of related oil storage and transportation facilities is guaranteed.
