Construction method of anti-corrosion road

Abstract

The invention discloses a construction method of an anti-corrosion road. The construction method includes the following steps of (1) construction site preparation, (2) anti-corrosion cement slurry preparation, (3) foam preparation, (4) anti-corrosion foam concrete preparation, (5) anti-corrosion foam concrete pouring, and (6) anti-corrosion foam concrete curing. The characteristic that coal ash and slag have good concrete active mineral admixtures is used, the coal ash and the slag are mixed in a foam concrete material, meanwhile, a proper amount of an additive is added, anti-corrosion foam concrete with the strength and sulfate attack resisting capacity better than those of ordinary silicate cement is prepared and applied to a road high fill, the service life of the road can be prolonged,and the operation stability of the road can be improved.

Description

technical field [0001] The invention relates to a construction method of an anti-corrosion road. Background technique [0002] In the western part of China, the terrain is dominated by mountains. The construction of expressways in mountainous areas is limited by terrain, geomorphology, and hydrogeological conditions. It is inevitable to carry out high-fill expansion construction on the original roadbed; at the same time, in order to meet the overall planning requirements of the country , and make better use of excavated earthwork resources, more and more high-fill roadbeds will be used in the reconstruction and expansion of expressways. In high-grade highways in mountainous areas, fill and excavation roadbeds account for 80%, and high fill embankments exceeding 20m are not rare. With the promotion of national policies and the rapid development of traffic construction, the structure of high embankments will be further improved in terms of quantity and height in the future re...

Problems solved by technology

As early as the 1950s, my country began to study the utilization of industrial waste residues. At present, the comprehensive utilization of some large-scale and wide-ranging industrial waste residues, such as fly ash and slag, has formed a series of quite mature comprehensive utilization technologies. It has been widely used in cement production, concrete admixtures and concrete products. At present, it is mainly used to increase the early strength of concrete, and has not fully utilized the potential activity of slag and fly ash.
