Engineering foundation for backfill soil, to the required density backfill soil should be strengthened, still need to use on the ground along the direction perpendicular to the wall of casting 10 cm thick concrete; Surrounding the scaffolding still need to due and drain. 
 

Sweeping bar cannot be directly placed on the ground, but the pad with thickness of not less than 50 mm stow-wood or plate. 
Poling longitudinal distance of 1.50 meters, poling horizontal distance of 1.00 meters, the size of the cross bar step distance of 1.80 meters, even the wall for the two step across the vertical spacing of 3.60 meters, 3 meters, the horizontal spacing using embedded fitting. 
The base, plate shall be accurately on the positioning line; Plate should be not less than 2 across, thickness of not less than 50 mm wood plate, steel channel may be adopted. 

Construction load control within 3.000 kN/m2. 
The general requirements of scaffolding:
Put a layer of fixed scaffolding full bottom, be put with scaffolding plank operation layer, since the operation layer, down to every 12 m spread a layer of scaffolding. 

Appropriate setting transverse brace frame body the corner. 
Master node two right-angle fastener center distance should not be greater than 150 mm, out side against the wall of the lateral horizontal length should not be greater than 500 mm. 

Ringlock scaffold poling extension in addition to the top the top step, the rest of the each layer of each step must adopt butt joint fastener connection. Shall not be used in the joint of two adjacent stud with step distance, synchronization across a vertical rod inside the two joints in the height direction of stagger distance apart should not be less than 500 mm.
