Pressure filling pile construction principle of occlusion after long spiral: using long spiral drilling to design depth, in the drilling of using concrete pump through the drill pipe center channel at the same time, with certain pressure to press the concrete to pile hole, the concrete to set the elevation, and then by means of reinforcing cage self-respect or special vibration equipment insert reinforcing cage in the concrete to the design elevation, the formation of reinforced concrete piles.
Long screw post pressure irrigationOcclusal pileConstruction principle:Using long spiral drilling to design depth, in the drilling of using concrete pump through the drill pipe center channel at the same time, with certain pressure to press the concrete to pile hole, the concrete to set the elevation, and then by means of reinforcing cage self-respect or special vibration equipment insert reinforcing cage in the concrete to the design elevation, the formation of reinforced concrete piles.
Advantages:
1The construction process without cement slurry or mud wall protection;
2, high pile forming efficiency;
3Stable pile quality;
4Low construction cost.
Disadvantages:
1Pile bottom can not be driven into rock;
2Low bearing capacity of single pile;
3The pile length is limited by the height of the drill frame.
Scope of application:
Suitable for high water table, easy to collapse hole, and long auger drilling machine can drill the stratum.
