Embodiment Construction

[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the following specific examples will further describe the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] as attached Figure 1-3 As shown, the present invention provides a kind of ditch land consolidation structure of the Loess Plateau for ditch reclamation, comprising original ditch shallow layer soil 2, filling loess foundation 3, farmland 4 and humus soil layer; original ditch shallow layer The soil 2 , the filling loess foundation 3 and the farmland 4 are arranged sequentially from bottom to top on the original ditch bedrock surface 1 of the ditch land to be improved, and the humus layer is spread on the surface of the farmland 4 .

[0041]In the present invention, the original ditch shallow soil 2 is...

Abstract

The invention discloses a gully land reclamation structure and method for loess plateau gully treatment and land reclamation. The gully land reclamation structure comprises original gully shallow soil, a filled loess foundation and a farmland. The original gully shallow soil, the filled loess foundation and the farmland are sequentially arranged on the original gully bed rock surface of the to-be-regulated gully land from bottom to top; the filled loess foundation comprises a bottom bearing layer, a middle transition layer and a top water filtering layer which are sequentially arranged from bottom to top, and the compaction degree of the bottom bearing layer, the compaction degree of the middle transition layer and the compaction degree of the top water filtering layer are gradually decreased. According to the invention, different filling soil layers achieve different functions by changing the compaction degree of the vertical filler of the filling project, so that the three functions of bearing weight, preventing and controlling collapsibility and filtering and draining water are achieved; the problem of filling soil of the loess plateau gully treatment and land reclamation can be effectively solved, safety and use of gully structures are guaranteed, and popularization and use are facilitated.

Description

technical field [0001] The invention belongs to the technical field of ditch land improvement on the Loess Plateau, and in particular relates to a ditch land improvement structure and method for ditch land reclamation on the Loess Plateau. Background technique [0002] With the development of the economy, there is a shortage of construction land in the Loess Plateau area; under the premise of moderate development, filling projects such as "cutting mountains and filling ditches" and "rectifying ditches to make land" have become the basis for resource development, utilization and reserve protection. One of the important decisions and development directions; the previous filling works expanded the cultivated land area to a certain extent; however, due to the lack of engineering experience and theoretical support, the newly created cultivated land was gradually destroyed over time. [0003] At present, most of the filling works in the gully-making and land-building areas of the ...
