Problems solved by technology

Although this method is convenient for construction and low in cost, it cannot prevent the corrosion damage of concrete.
[0008] 4. Use high-performance concrete or composite concrete: When the foundation is poured with high-performance concrete or composite concrete as a whole, the anti-corrosion effect of the foundation is excellent, but the cost will increase greatly

Abstract

The invention discloses a saline-alkali soil anti-corrosion foundation with an enamel protective layer and a preparation method thereof. The saline-alkali soil anti-corrosion foundation comprises an enamel anti-corrosion cushion layer, a reinforced concrete foundation body and an enamelized anti-corrosion layer; the enamel anti-corrosion cushion layer is paved with C20 plain concrete mixed with shell chips, and is provided with the reinforced concrete foundation body; the reinforced concrete foundation body is composed of C40 self-compacting concrete and steel bars, and the external of the reinforced concrete foundation body is provided with the enamelized anti-corrosion layer; the enamelized anti-corrosion layer is made of functional composite ceramic granule mortar through pouring. According to the saline-alkali soil anti-corrosion foundation with the enamel protective layer and the preparation method thereof, a foundation pit is excavated and the enamel anti-corrosion cushion layeris prepared; then, first formwork is carried out and foundation reinforcement and column ribs binding are performed on the enamel anti-corrosion cushion layer, a concrete foundation body is poured, second erecting template is conducted on the outside of the reinforced concrete foundation body, and the enamelized anti-corrosion layer is poured; finally, after the enamelized anti-corrosion layer isdried, the foundation pit is backfilled. The saline-alkali soil anti-corrosion foundation with the enamel protective layer and the preparation method thereof have good durability and corrosion resistance, and greatly prolong the service life of the foundation.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a corrosion-resistant foundation suitable for saline-alkali land and a preparation method thereof, in particular to a corrosion-resistant foundation suitable for saline-alkali land with good economic benefits, environmental protection and pollution-free, and a preparation method thereof; The durability of the prepared foundation in 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 ...
