Problems solved by technology

In the prior art, in view of various landforms in hilly areas, in the study of topsoil stripping engineering in land consolidation engineering, the operation procedures are relatively complicated by dividing the field, stripping on both sides, stacking, and backfilling after leveling, and other terrains have not been solved yet. Topsoil stripping and leveling problems
In the actual land consolidation construction, many project units seldom carry out and implement the topsoil stripping work, and the topsoil stripping operations have been carried out, and the specific operation methods are more based on the feelings of the on-site construction personnel or years of construction experience. , the lack of scientific theoretical basis

[0050] (1) Divide the field to be stripped of topsoil into 4 strips, divide the first strip into "filling area" and "excavation area" and set the small field (soil) ridge as the boundary to facilitate filling; Stripping the topsoil layer of the 1st section of the "digging area" and the 1st section of the "excavation area" and storing it in the topsoil storage place; storage, maintenance, and management; land leveling for the first strip after stripping; A strip of soil layer is divided into two layers: surface soil layer (upper 20-40cm) and lower soil layer X;

[0051] (2) Then extract the lower soil layer from the 1st section of the "excavation area" and push it to the 1st section of the "filling area" with a bulldozer, so that the two can reach a rough level;

[0052] (3) Move the topsoil of the 2nd block and the 2nd block to the 1st block and the 1st block respectively, and level it to reach the design elevation;

[0053] (4) Follow the method in step 3 and so on, repeat t...

Abstract

The invention discloses a method of soil reclamation project topsoil stripping. The method includes the steps that a field with to-be-stripped topsoil is divided into a plurality of areas, topsoil of the first area is stripped, stored and stacked on a topsoil stacking place outside the field, storage, maintenance and management are carried out, soil leveling is carried out on the first area without the topsoil, designed elevation is achieved after leveling, the topsoil of a second area is stripped to the first area after being leveled, soil leveling is carried out on the second area without the topsoil, the designed elevation is achieved after leveling, the topsoil of a third area is stripped to the second area after being leveled, soil leveling is carried out on the third area without the topsoil, the designed elevation is achieved after leveling, finally the stripped topsoil of the first area is filled back into a last area after being leveled, and the designed elevation is achieved. Accordingly, soil resources are effectively protected, construction is convenient, and efficiency is improved.

Description

technical field [0001] The invention relates to a land leveling technology, in particular to a method for stripping topsoil in a land consolidation project. Background technique [0002] The land leveling project is one of the four major projects of land consolidation projects. Doing a good job in land leveling is beneficial to the efficiency of mechanical operations, rational irrigation and drainage, water conservation, improvement of labor productivity, and soil improvement, soil conservation, water conservation, and fertilizer conservation. It plays an important role. Topsoil stripping, soil transfer and topsoil backfilling are the reasonable construction sequence and operation steps of land leveling engineering, so the process of topsoil stripping should run through the whole construction process of land leveling. [0003] In land development and improvement projects, the role of soil is even more important. After all, the essence of land improvement projects is the mov...
