use an excavator to move stones to build a retaining wall !

The following are the general process methods for using an excavator to move stones to build a retaining wall:

Construction Preparation

- Material preparation: Select appropriate stones. The size and shape of the stones should be as convenient as possible for the excavator to grab and stack. The stone texture should be hard, with no obvious defects such as cracks.
- Site preparation: Clear the debris and soft soil in the construction area of the retaining wall foundation to ensure a good working site for the excavator. According to the design requirements of the retaining wall, set out and position to determine the position and foundation range of the retaining wall.
- Machinery inspection: Check the performance of the excavator, including the flexibility of the mechanical arm and the integrity of the bucket, to ensure that the excavator can work normally.

Foundation Construction

- Foundation excavation: Use the excavator to excavate the retaining wall foundation. The depth and width of the foundation should meet the design requirements. Generally, rough excavation is carried out first, followed by fine trimming.
- Foundation treatment: After the excavation is completed, tamp the bottom surface of the foundation. If the soil quality is poor, crushed stones can be laid for reinforcement.

Stone Handling and Stacking

- Stone grabbing: Operate the excavator and use the bucket to grab stones from the stone stockpile. For larger stones, adjust the angle of the bucket to make it easier to insert under the stone for grabbing.
- Transportation: Slowly move the grabbed stone to the construction position of the retaining wall. During the movement, pay attention to maintaining the balance and stability of the excavator to avoid the stone from falling.
- Stacking: Start stacking from the corner of the retaining wall and place the stone on the foundation. When stacking, try to make the stones closely interlock. For irregular stones, the position and direction can be adjusted through the excavator to make the wall surface flat. Large stones are placed on the lower layer as the foundation, and smaller stones are used to fill the gaps.

Gap Filling

- Selection of filling materials: Small stones, sand, etc. are commonly used filling materials.
- Filling operation: Use the excavator to scoop up the filling material and then pour it into the gaps between the stones and slightly compact it to make the gaps filled densely.

Wall Surface Trimming

- Use the edge of the excavator's bucket to appropriately trim the retaining wall surface to make the wall surface in the same plane or meet the slope requirements of the design. For the stones protruding from the wall surface, gently push them back into place.
