Before constructing the slope, farmers level the slope with hoes and rakes.

When leveling slopes manually, there are the following precautions:

I. Preparation before construction

1. Site investigation
- Conduct a detailed investigation of the geological conditions of the slope to understand the soil type, rock distribution, groundwater level, etc. For example, if the groundwater level is high, drainage measures may be needed to prevent dangers such as landslides during construction.
- Measure the slope gradient and height, and determine the leveling range and target gradient to formulate a reasonable construction plan.
2. Preparation of tools and materials
- Prepare appropriate tools such as hoes, shovels, and crowbars to ensure that the quality and quantity of tools can meet construction needs.
- Prepare protective materials such as protective nets and sandbags as needed to prevent earthwork collapse.

II. Construction process

1. Layered construction
- Generally, the method of layered excavation and leveling should be adopted. The excavation depth of each layer should not be too large, usually controlled at about 0.3 - 0.5 meters to prevent earthwork collapse.
- After excavation and leveling of each layer, check in time whether the slope meets the design requirements. If there is a deviation, adjust it in time.
2. Drainage measures
- Set up a temporary drainage system on the slope, such as drainage ditches or drainage pipes, to drain rainwater and groundwater in time. For example, intercepting ditches can be excavated above the slope to prevent rainwater from scouring the slope.
- Avoid large-scale earthwork excavation and leveling work on rainy days to prevent landslides caused by excessive soil moisture.
3. Safety protection
- Construction personnel should wear protective equipment such as safety helmets and safety ropes to prevent slipping on the slope or being injured by rolling earthwork.
- Set up warning signs at the edge of the slope to prevent unrelated personnel from entering the construction area.
4. Earthwork treatment
- The excavated earthwork should be stacked reasonably to avoid stacking too much earthwork above the slope and increasing the load on the slope.
- If it is necessary to transport earthwork outward, an appropriate transportation route and method should be selected to prevent pollution to the surrounding environment.

III. Inspection after construction

1. Slope inspection
- After the construction is completed, use measuring instruments to accurately measure the slope gradient of the slope to ensure that the slope meets the design requirements.
2. Stability inspection
- Check the stability of the slope. Preliminary judgment can be made by observing whether there are cracks or slip signs in the earthwork. If necessary, professional personnel can be invited to conduct geotechnical engineering tests to ensure that there will be no safety problems in the subsequent use of the slope.
3. Vegetation restoration (if necessary)
- If vegetation restoration is required on the slope, turf or trees should be planted in time to enhance the erosion resistance and stability of the slope.

Manual slope leveling requires strict compliance with relevant construction specifications and safety requirements to ensure construction quality and personnel safety.
