Method for leveling land according to soil layer thicknesses

Abstract

The invention discloses a method for leveling land according to soil layer thickness. The method includes the following steps that firstly, a plurality of probe points are selected from a land region according to the cross interval method or the s-shape method or the quincunx and diagonal method or the chessboard method, wherein elevation differences exist between the probe points; secondly, the soil layer thicknesses are measured, namely, the thicknesses of spaces between the probe points and a gravel layer or a bed rock layer are measured according to the soil profile digging method or the soil drilling method or the ground penetrating radar method and are the soil layer thicknesses; thirdly, the land is leveled, wherein the gradient of the leveled land is smaller than or equal to 0.5%. The profile of soil is detected, the land is leveled according to soil layer thickness general investigation and exploration results to ensure that the soil layer thicknesses meet land engineering construction standards and corn growth requirements, and the earthwork transfer workload is reduced.

Description

technical field [0001] The invention relates to the field of land consolidation, in particular to a method for land leveling according to the thickness of the soil layer. Background technique [0002] At present, the goal of land consolidation in my country is mainly to increase the area of ​​cultivated land and ensure the dynamic balance of the total amount of cultivated land. Land consolidation planning projects are more concerned with increasing the quantity of cultivated land, while ignoring the quality of cultivated land, for example, ignoring the thickness of the newly added cultivated land soil layer . As an important engineering measure of land consolidation, land leveling plays an extremely important role in ensuring the smooth completion of land consolidation projects. As an important preparatory work in the early stage of the land leveling project, the general survey of soil layer thickness directly regulates the soil profile structure of the newly added cultivate...

AI Technical Summary

Problems solved by technology

However, at present, most of the early stage of land leveling lacks the exploration of the thickness of the soil layer, resulting in the thickness of the soil layer in the later stage of leveling cannot meet the construction standards of land engineering and the needs of crop growth, making the economic, social and ecological benefits of land consolidation unable to achieve the most ideal coupling state.
