Scope

Main technical content: 1. This standard applies to the design, construction, and acceptance of foundation piles and engineering pile foundations in construction projects. 2. For in-situ soil pressure grouting concrete piles, a long spiral drill rod is used to drill to the designed depth of the pile tip. Concrete is pumped continuously under high pressure from the bottom of the pile to the top through the hollow pipe of the drill rod, forming a plain concrete pile. While pulling up the drill rod, the soil is replaced by the spiral blades. The entire reinforcing cage is vibrated and inserted into the plain concrete pile using special equipment, forming a reinforced concrete grouting pile.
