Structure and method for construction of soil body in sandy land

Abstract

The invention relates to the field of edaphology, and discloses a structure for construction of a soil body in a sandy land. The structure comprises a mixed layer, a clay layer and a sandy soil layer,wherein the clay layer is laid above the sandy soil layer; and the mixed layer is made by mixing sandy soil and clay, and laid above the clay layer. The invention discloses a method for constructionof the soil body in the sandy land. The method comprises the following steps: sandy land leveling: a step of selecting a datum plane of the sandy land, pushing the sandy soil by utilizing machinery, wherein the sandy soil at a high position is pushed down, and the sandy soil at a low position is padded, and carrying out compaction; clay crushing: a step of transporting the clay to a leveled area of the sandy land, crushing the clay, and carrying out sieving; covering: a step of covering the leveled area of the sandy land with crushed clay, and covering the crushed clay with the sandy soil so as to form a covering layer; and mixing: a step of ploughing the covering layer, and mixing the sandy soil with the crushed clay so as to form the mixed layer. According to the invention, physical structure complementarity between the clay surrounding the sandy land and the sandy soil is utilized to reconstruct the soil body of the sandy land, so the utilization obstacle of the sandy land is thoroughly solved; production capacity of the sandy land is improved; materials can be available nearby; engineering cost is low; no pollution is generated; and persistence is strong.

Description

technical field [0001] The invention relates to the field of soil science, in particular to a sandy land soil construction structure and a method thereof. Background technique [0002] In the process of urbanization, construction land occupies high-quality cultivated land, resulting in a shortage of land and food, and a balance between occupation and compensation is required. Therefore, the remediation and utilization of unused land is the key. The Mu Us Sandy Land is one of the four major sandy lands in China, with suitable natural conditions and great potential for remediation and utilization. However, most of the current remediation methods focus on sand prevention and sand fixation, and have not fundamentally solved the problems of running water, fertilizer, and soil in sandy land, so that the degraded sandy land can be transformed into productive newly-added cultivated land. Secondly, some remediation technologies are costly, slow to take effect, poor in sustainabilit...
