Construction flow of undisturbed earth taking and pressure pouring concrete pile with full protective cylinder

The construction of undisturbed soil taking concrete cast-in-place pile with full protective simplicity adopts dual-power drill with built-in spiral blades to drill down and cut the soil to form the pile diameter. At the same time, the undisturbed soil in the protective simplicity is removed, and the concrete is inserted into the steel cage after being pressed and the protective simplicity is removed to form reinforced concrete piles.
