The land leveling construction method is as follows: 1. Measurement and setting out: According to the coordinate control points and level measurement points provided by the design unit, determine the leveling excavation area and filling area, and carry out earthwork according to the measurement results and design drawings Make balanced calculations and formulate reasonable earthwork scheduling plans. If there are major errors, the construction unit and the design unit should be invited to coordinate and study solutions. If there are major changes to the design, changes should be made in accordance with the change procedures prescribed by the Department of Land and Resources. After the elevation review, the underlying foundation of the field should be inspected to see if there is sand leakage or silt under the farming layer. If so, coordination should be carried out as soon as possible to ensure the safety of construction machinery and personnel and the anti-seepage capability of the farming side. 2. Earthwork leveling construction for terraces and strip fields: Considering the earthwork balance in the leveling area, before bulldozing, use machinery and manual work to thoroughly remove tree stumps, tree roots, weeds, garbage, waste residue and other obstructions in the excavation area. After clearing, first use a bulldozer to peel off 20cm of the original cultivated soil on the surface in layers, and then stack it in the grid. It needs to be covered with plastic sheets during heavy rains to avoid heavy rains and heavy soil loss. After the topsoil is stripped, a grader is used to perform fine leveling work. In areas with large local height differences, scrapers are used to shovel earthwork and backfill. Try to carry out excavation and filling at the same time. After the grid is leveled, the elevation meets the design requirements. When leveling, the principle of proximity should be adopted. Earthwork higher than the design field elevation should be excavated and backfilled to nearby fields lower than the design field elevation. During excavation and backfilling, it should be ensured that there is sufficient water-retaining layer in the field before the topsoil is backfilled. To prevent the bottom of the topsoil layer from becoming a leaky layer, attention should be paid to the control of field surface elevation during construction. In accordance with the design requirements, a scraper is used to transport the soil, and a bulldozer is used to level the tillage layer, and the topsoil of the newly cultivated fields is loosened using a bulldozer's ripper to rake and loosen the soil. 3. Field ridge construction. After the topsoil backfill has passed the inspection and acceptance, the field ridge construction shall be carried out according to the design requirements; the field ridge shall be tamped straight to prevent water leakage, and the inner side of the field ridge shall be tamped with sticky soil, and water shall be released for trial storage. The soil with strong viscosity should be selected on the outside of the field ridge, and the soil should be compacted layer by layer and then sloped and beaten firmly. 4. Soil fertilization: Since the soil after leveling is poor in nutrients and basically cannot meet agricultural production, it is necessary to fertilize the newly added soil. Farmland fertilizers should be applied to the cultivated land in the leveling area to fertilize.
