Abstract

The invention discloses a waterproof and anti-corrosion prestressed hollow pipe with a coating and relates to the technical field of buildings. The waterproof and anti-corrosion prestressed hollow pipe with the coating comprises a pile body, wherein a liquid rubber spray coating material coating and a compound protection layer are sequentially sprayed on the pile body of the waterproof and anti-corrosion prestressed hollow pipe with the coating from inside to outside, and the liquid rubber spray coating material coating is sprayed on the inner wall surface of the pile body. The waterproof and anti-corrosion prestressed hollow pipe with the coating, disclosed by the invention, is simple in structure, the liquid rubber spray coating material coating is sprayed on the surface layer of the pile body of the prestressed pile, and after a film is formed, the film is dried under natural conditions and a complete and seamless adhesive film is formed, so that the waterproof and anti-corrosion prestressed hollow pipe with the coating has great chemical resistance, strong resistance against strong acid, alkali and salts and very high anti-puncture performance.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a waterproof and anti-corrosion prestressed hollow pile with coating. Background technique [0002] The foundation of a building is an important part of the whole building, and the foundation is generally located underground. It has been eroded by soil, water and chemicals for a long time. The waterproof or anti-corrosion performance directly affects the service life of the building foundation. For example, the widely used forecasting Stress piles are generally reinforced concrete structures, which are directly used to support buildings underground. Although reinforced concrete has certain waterproof and anti-corrosion properties, it has a certain density. Long-term water erosion and erosion of some chemical substances will affect the pile body. strength, thereby increasing the maintenance cost of the building. Contents of the invention [0003] In order to solve the a...
