Problems solved by technology

[0002] Alkali slag is the industrial waste produced during the production of soda ash by ammonia-soda method. At present, the treatment and utilization technology of alkali slag has made great progress in recent years. For example, Chinese patent CN95106293. A method for preparing slag engineering soil, but this method requires long-term natural drying, dehydration and solidification, not only needs to occupy a large amount of construction sites, but also is not suitable for use in areas with humid weather due to climate constraints, and as in Chinese patent CN95108024.5, drying The method for processing the engineering soil made of alkali slag also discloses a preparation method of the alkali slag engineering soil. This method does not need to be completely dried and solidified, but the bearing capacity of the engineering soil prepared by this method is too low, generally less than 1MPa, which cannot meet needs of existing projects

Abstract

The invention provides a preparation method of super basic residue engineering soil. Each material is in percentage by weight, and the preparation method comprises the following steps of: (1) mixing and agitating basic residue and coal ash according to 1:0.15-0.2, and airing until the moisture content becomes 47-55% to prepare coarse super basic residue engineering soil; (2) mixing and agitating the super basic residue engineering soil material, cement and lime according to 1:0.2:0.05 or 1:0.15:0.1 to prepare a crude basic residue engineering soil material; (3) laying the crude basic residue engineering soil material according to the thickness of 0.25-0.35 cm layer by layer, and carrying out rolling compaction; and (4) repeating the step (3) until reaching the total thickness requirement of laying to prepare the super basic residue engineering soil. The invention has the advantages of simple process, large basic residue consumption, low basic residue treatment cost and no need of long-term drying because of the technical scheme.
