Introduction to construction technology of undisturbed earth taking and filling pile with full retaining cylinder
Process Introduction:
1The undamaged soil taking and filling pile with full retaining cylinder is drilled and cut into soil by double power drill with built-in spiral blades in full retaining cylinder to form pile diameter;
2Take out the soil in the protective tube without the original condition;
3After pouring or pressing concrete, the steel cage is inserted into the steel cage, and the reinforced concrete pile is formed after pulling out the protective cylinder.
Equipment features:
1And the power of the power head are respectively360kN.mand180kN.m , strong power;
2, the maximum lifting force180t;
3, the rig is equipped with fuselage self-balancing adjusting device and verticality controller;
4, the control room is equipped with pile machine drill pipe down and lift gear control device, can accurately control the drill pipe down and lift speed.
Applicable soil layer:
1And clay layer(Silt clay and silty soil)Silt and sand;
2, high water table and high confined water layer.
Technical Features:
1Hole forming without expanding diameter, saving concrete;
2Do not use mud wall protection, high pile quality;
3No mud production, green environmental protection;
4High pile forming speed;
5, the soil interference is small, the construction process has little influence on the pile and the surrounding environment, especially suitable for the project with high pile density;
6.No hole collapse, no neck shrinkage, high vertical precision, reliable quality.
