Problems solved by technology

Due to regional differences and the use of special environments, such as wet geology, a large amount of inorganic acid-nitric acid, hydrochloric acid, inorganic alkali-sodium hydroxide, potassium hydroxide, etc., the use of existing galvanized corrugated steel sheets The lifespan will be very short, and it will be corroded in a short time
In addition, the existing galvanized corrugated steel sheet is an easy conductor, and its use in engineering construction is limited.

Abstract

The invention discloses a metal corrugated lining plastic steel plate pipe culvert which comprises a corrugated pipe culvert body. Epoxy resin layers are arranged on the inner wall and the outer wall of the corrugated pipe culvert body and adhere to the inner wall and the outer wall of the corrugated pipe culvert body integrally. According to the metal corrugated lining plastic steel plate pipe culvert, the epoxy resin layers are arranged on the inner wall and the outer wall of the corrugated pipe culvert body. The epoxy resin layers have the following advantages that (1) the adhesion capacity between the epoxy resin layers and the corrugated pipe culvert body is high, and the epoxy resin layers can adhere to the corrugated pipe culvert body integrally; (2) the epoxy resin layers have high adhesion intensity and other physical performance, the adhesion process is simple and easy to master, and the economic effect is good; (3) the epoxy resin layers have the excellent characteristics of water leakage prevention, oil leakage prevention, insulation, chemical corrosion resistance and the like; and (4) the temperature resistance of the epoxy resin layers is good, the epoxy resin layers can operate within 150-200 DEG C for a long term, and the epoxy resin layers can resist the temperature ranging from minus 55 DEG C to minus 50 DEG C. The characteristics show that the service life of the pipe culvert can be prolonged as the epoxy resin layers and a metal corrugated steel plate are combined into a whole.

Description

technical field [0001] The invention belongs to the technical field of bellows, in particular to a metal corrugated plastic-lined steel plate pipe culvert. Background technique [0002] The surface of the traditional circular corrugated steel pipe is treated by hot-dip galvanizing technology to increase the anti-corrosion effect. Due to regional differences and the use of special environments, such as wet geology, a large amount of inorganic acid-nitric acid, hydrochloric acid, inorganic alkali-sodium hydroxide, potassium hydroxide, etc., the use of existing galvanized corrugated steel sheets The lifespan will be very short, and it will be corroded in a short time. In addition, the existing galvanized corrugated steel sheets are easy conductors, and their use in engineering construction is limited. Contents of the invention [0003] In view of this, the object of the present invention is to provide a metal corrugated plastic-lined steel pipe culvert, which has the advant...
