Embodiment 1

[0043] A safe plastic-fixing construction technology for fiber-reinforced plastic double-layer lining of underground storage tanks, the specific construction process includes:

[0044] Step 1: Degreasing, derusting, phosphating and passivating the surface of the inner tank body

[0045] Use degreasing and derusting agents to clean up the oil, rust and other harmful substances attached to the inner wall of the storage tank until the inner surface of the tank is exposed to the original color of the metal, and at the same time, phosphating and passivating the metal surface to prevent further corrosion; The reaction process of degreasing and derusting agent is a gasification process, and only residues are left after the reaction; At the same time of operation, forced air induction must be implemented in the tank, and the waste gas and other toxic gases generated during the degreasing and derusting process must be discharged out of the tank in time, so as to ensure the safety of th...

Abstract

The invention relates to a safety solid plasticization construction process for a fiber reinforced plastic dual-layer lining of an underground storage tank. The safety solid plasticization construction process is characterized in that the specific construction material selection and process comprise the steps of conducting oil and rust removal, phosphorization and passivation on the surface of aninner tank body; blocking holes; reinforcing the tank wall of an original tank body; removing a triangular supporting frame in the tank body; manufacturing a new fiber reinforced plastic reinforcing rib ring; and achieving dual-layer lining laminating design. The old tank body directly serves as a solid plasticization object, reinforced plastics manufactured by low styrene volatilization safety solid plasticization resin and fibers are adopted to be manufactured into a fiber reinforced plastic (FRP) tank body with dual-layer walls in the old tank body, the investment cost for replacing the tank body is greatly reduced, the construction period is effectively shortened, the most important thing is to guarantee construction work safety, and the feasibility of non-integral ground breaking construction is guaranteed. Full consideration is taken into the whole construction process, the corresponding solutions respond to all kinds of problems, and the purposes of safety work and reliable construction are realized.

Description

technical field [0001] The invention relates to a safe plastic fixing technology for underground storage tanks, and belongs to the technical field of safe plastic fixing construction methods for underground storage tanks. Background technique [0002] Underground storage tanks are usually used to store more dangerous materials, such as: gasoline, diesel, alcohol liquids and other chemicals. At present, most of the existing storage tanks are made of steel plates. The storage tanks have been buried underground for a long time and are corroded by groundwater, acid, alkali, salt and seepage. In the long run, the tanks are prone to rust, cracks and holes. To avoid safety accidents, the tank body should be replaced at this time; although some tank bodies are not seriously corroded, after a long period of use, for the sake of safety, the phenomenon of material aging must also be replaced. [0003] Replacing the storage tank is a rather large project, which needs to break ground ...
