Abstract

The invention discloses a saline soil enamelized overall anti-corrosion foundation and a preparation method. The anti-corrosion foundation comprises an enamelized anti-corrosion cushion layer and an enamelized foundation body. The enamelized anti-corrosion cushion layer is paved with C20 plain concrete mixed with high-strength and high-toughness broken shells. The enamelized anti-corrosion cushionlayer is provided with the enamelized foundation body. The enamelized foundation body is composed of self-compacting concrete and steel bars mixed with high-strength and high-toughness boron carbide-silicon carbide (B4C-SiC) functional composite ceramic particles. The method comprises the steps that a foundation pit is first excavated to prepare the enamelized anti-corrosion cushion layer; then,template erecting, foundation reinforcement and column ribs binding are performed on the enamelized anti-corrosion cushion layer, and the enamelized foundation body is prepared by pouring; finally, the template is removed, and the foundation pit is backfilled and tamped. The foundation prepared by the invention is greatly improved in the durability in the saline soil than an ordinary foundation, and the safety of the foundation can be ensured within the service life.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to an anticorrosion foundation suitable for saline-alkali land and a preparation method thereof, in particular to an environmentally friendly and pollution-free super corrosion-resistant foundation suitable for saline-alkali land and a preparation method thereof; The durability of saline-alkali land is greatly improved compared with ordinary foundations, and the safety of the foundation can be guaranteed within the service life. Background technique [0002] my country has a vast territory and complex and diverse geological conditions. With the country's vigorous development of the west, power transmission lines and railways will inevitably pass through saline-alkali areas with highly corrosive soil. As the load-bearing structure of the transmission tower and the railway, the safety and reliability of the foundation are crucial to the safety of the superstructure. However, ...
