Embodiment Construction

[0033] like figure 1 As shown, the present invention comprises oil tank inner wall 1, and oil tank inner wall 11 is provided with liner, and described inner liner is successively made of primer layer 2, first anti-leakage layer 3, first structure layer 4, hollow layer from inside to outside. Layer 5, second structural layer 6, second anti-leakage layer 7, third structural layer 8, and antistatic layer 9 are compounded.

[0034] The process of rebuilding the lining of buried oil tanks includes the following steps:

[0035] a. Cleaning and derusting the inner wall of the oil tank 1: Use a high-pressure cleaner for sandblasting cleaning, and the derusting grade is Sa2.5;

[0036] b. Drying: Drain the accumulated water and sand in the oil tank, and use a heating fan to heat and dry the oil tank; in actual operation, the concentration of oil and gas in the tank after cleaning the tank should be lower than the lower limit of the explosion limit (gasoline explosion limit 1.0%~ 6%, ...

Abstract

The invention discloses a buried oil tank lining transformation technology. The buried oil tank lining transformation technology comprises the steps that oil tank inner wall cleaning and rust removal,drying, inner component treatment, primer layer brush application, leakage detecting and repairing, first anti-leakage layer pavement, first structure layer pavement, hollow layer pavement, second structure layer pavement, second anti-leakage layer pavement, third structure layer pavement, anti-impact plate arranging and anti-static layer pavement are conducted,and finally, pressure monitoring equipment of a gap layer is arranged in a manhole well, a line is guided to display monitoring equipment in a station room through a buried protection pipe, and transformation is finished after qualification is achieved through debugging. According to the buried oil tank lining transformation technology, lining transformation is directly conducted on a buried oil tank, oil tank replacement or excavation is not needed, and therefore the input cost is greatly reduced; since the buried oil tank is located underground for a long term, mud and sand backfilled on the periphery are relatively stable after being settled for a long term, the oil tank pipe wall stress is relatively balanced, and after oil tank lining treatment, the strength of the oil tank wall is improved.

Description

technical field [0001] The invention relates to an oil tank, in particular to a process for rebuilding the lining of an underground oil tank. Background technique [0002] With the development of the automobile industry, the number of automobile gas stations is increasing day by day. Most of the oil storage tanks in gas stations in my country adopt steel horizontal structures, and are generally single-layer structures. Since the oil storage tanks are placed underground, they are vulnerable to the surrounding moisture Due to the influence of the environment and oil erosion, the tank body is easily corroded, resulting in leakage of oil storage, which will cause serious pollution to soil and groundwater resources. [0003] The buried double-layer oil tank is a new safety and environmental protection technology for gas stations enforced by GB50156-2012 "Code for Design and Construction of Automobile Refueling and Gas Stations". The purpose is to use buried oil tanks with double-l...
