Large-diameter steel pipe anti-slide pile anti-corrosion protection layer and construction method thereof

Abstract

The invention belongs to the technical field of steel pipe anti-slide pile protection, and particularly relates to a large-diameter steel pipe anti-slide pile anti-corrosion protection layer and a construction method thereof. The problems existing in existing anti-corrosion coating protection and electrochemical protection are solved. According to the scheme, the large-diameter steel pipe anti-slide pile anti-corrosion protection layer comprises a concrete core pile poured on a slide mass and a slide bed, wherein a steel pipe is arranged on the concrete core pile, and a fiber concrete protection layer, a macromolecule corrugated pipe and a grouting body are sequentially arranged on the steel pipe from inside to outside. The specific construction method comprises the steps that mechanical hole forming or hole digging is carried out, and the hole depth is checked; the steel pipe is hoisted, positioned and temporarily fixed; the macromolecule corrugated pipe is mounted; a positioning support is mounted and unfolded; the concrete core pile is poured; the fiber concrete protection layer is poured; and the grouting body is poured. The technology of the large-diameter steel pipe anti-slide pile anti-corrosion protection layer can be adopted in a site with high corrosivity and can also be used in an area with the high underground water level, the problem that a steel pipe anti-slide pile is poor in corrosion resistance can be solved, and the durability and service performance of the steel pipe anti-slide pile are improved.

Description

technical field [0001] The invention belongs to the technical field of steel pipe anti-sliding pile protection, and particularly relates to a large-diameter steel pipe anti-sliding pile anti-corrosion protection layer and a construction method thereof. Background technique [0002] my country's topography is diverse and the topography varies greatly. With the development of economy and society, infrastructure construction is also advancing rapidly, and various engineering facilities are gradually increasing in mountainous and hilly areas, such as new roads and railways of various grades, large reservoirs, and mining of mineral resources. Wait. With the increase of engineering construction and human activities, various types of landslides are also occurring, especially in mountainous areas with abundant rainfall, landslide disasters are more frequent, and the property losses and casualties caused by landslide accidents are also very serious. At the same time, landslides will a...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the problems of durability and construction difficulty in the existing anti-corrosion coating protection, the present invention provides a large-diameter steel pipe anti-slide pile anti-corrosion protection layer and its construction method. The large-diameter steel pipe anti-slide pile anti-corrosion protection provided by the invention Layer technology can be used in highly corrosive sites, and can also be used in areas with high groundwater levels, which can overcome the problem of poor corrosion resistance of steel pipe anti-slide piles and improve their durability and service performance
