Foam light soil construction method

Abstract

The invention discloses a foamed light soil construction method. After the construction of a reinforced concrete protection wall and a soil subgrade is completed, foamed light soil is poured on the soil subgrade, and a galvanized wire mesh, a cushion layer and a reinforced concrete pavement are adopted on the foamed light soil so as to form a pavement structure; the foamed light soil is prepared through the steps of preparing a foaming agent into foams by using a physical method, then adding the foams into slurry prepared from cement, aggregates, admixtures, additives and water through a foamed light soil automation machine, mixing and stirring the obtained mixture through the foamed light soil automation machine, then conveying the obtained object by a guide pipe, and carrying out pouring molding and maintenance on the obtained object so as to obtain microporous light soil. The method disclosed by the invention greatly improves the construction quality of the foamed light soil, and effectively guarantees the molding standard of the foamed light soil.

Description

technical field [0001] The invention relates to a construction method for roadbed filling, in particular to a foam light soil construction method used in special occasions. Background technique [0002] With the development of the economy, my country's infrastructure construction has entered a golden age in recent years. However, land acquisition, soft foundation treatment in the project, and bridgehead and other building end treatment are still a large part of the project cost; the uneconomical nature of traditional fillers , not environmental protection, and unsafety are becoming increasingly prominent. Foam lightweight soil is a new type of lightweight environmental protection material. It has been used abroad for decades. Since it was introduced from Japan in 2001, it has been used in key projects such as Guangdong, Beijing, and Hebei, and has achieved good results. So far, this technology has been applied to about 3 million m3 in Japan, and has been successfully applied...
