Construction method for land arrangement of rolling ground by topsoil stripping and backfilling

Abstract

The invention discloses a construction method for a land arrangement of a rolling ground by topsoil stripping and backfilling. The construction method comprises the following steps of: firstly, carrying out a land division, selecting the lands needing to be arranged, and dividing the lands into multiple sections; then carrying out a topsoil stripping, carrying out the topsoil stripping from the middle section to the lands on two sides, and uniformly piling the stripped topsoil on two sides of the lands; then carrying out a land flattening; flattening and reshaping the lands which are processed by the topsoil stripping and protecting side slopes; finally, carrying out a topsoil backfilling, and carrying out the uniform topsoil backfilling from two sides of the land to the middle of the flattened land. The construction method provided by the invention effectively guarantees that: the agricultural acreage is not reduced, the topsoil resource is not lost, the topsoil space match is optimized, the configuration of soil body is good, the quality of the soil is not reduced and the production of the crop is increased; and the construction efficiency of the method is higher.

Description

technical field [0001] The invention relates to a land leveling technology for land consolidation, in particular to a construction method for stripping and backfilling topsoil for land consolidation in hilly areas. Background technique [0002] It takes 300-400 years for every 1cm thick topsoil to be formed in nature. Surface soil is a precious resource that is difficult to regenerate in a short period of time. It is the most valuable part of arable land resources, the fundamental basis of comprehensive grain production capacity, the basis for crop production increase, and the core of arable land productivity. The promotion of soil stripping and backfilling of the cultivated layer is an important means to improve the quality of cultivated land, an effective way to ensure the quantity of cultivated land and ensure the balance of cultivated land occupation and replenishment, and an important measure to achieve the goal of cultivated land protection. It plays a positive role in...

AI Technical Summary

Problems solved by technology

[0003] At present, in the construction of land leveling projects, large-scale scrapers, excavators, bulldozers, loaders, graders, dump trucks and other machinery are commonly used, which will cause great damage to the cultivated layer, especially in hilly areas. Topsoil stripping and backfilling During construction, there is no topsoil stripping and backfilling construction method that ensures no reduction in cultivated land area, no loss of topsoil resources, optimization of topsoil spatial configuration, excellent soil configuration, no reduction in soil quality, increased crop production, and improved work efficiency.
