Full protection of JaneUndisturbed concrete cast-in-place pileIn the construction, a double-power drill with built-in spiral blades is adopted to drill down and cut soil to form pile diameter. At the same time, the soil in the simplified protection is removed, and the concrete is inserted into the steel cage after being pressed and the reinforced concrete pile is formed after the simplified protection is pulled out. Can also be used to rotary pressure steel casing (guard cylinder)), grab and other equipment take out the hole forming process of the soil inside the guard, install the steel cage after the hole forming, and fill the concrete of the pile body. It is suitable for clay soil layer, silt soil, sandy soil and high groundwater level, high confined water formation.
1,Undisturbed concrete cast-in-place pileCharacteristics of process technology
(1) No diameter expansion for hole formation, saving concrete.
(2) Do not use mud wall protection, high pile quality.
(3No mud produced, green environmental protection.
(4) high pile forming speed.
(5) The soil disturbance is small, and the construction process has little influence on the first pile and the surrounding environment, which is especially suitable for the project with high pile density.
(6No hole collapse, no neck shrinkage, high verticality, reliable quality.
