SP - Soil Displacement

 
SP SOIL DISPLACEMENT PILES
 
ENTECO equipment are specially designed to be applied with SP (Soil Displacement) applications, with very advanced engineering solutions and innovative research, special patented tools to provide customers with high efficiency and high productivity rigs.

Enteco can provide SP applications for piling up to 1000 mm diameter to a single stroke depth of 46 meters.

ENTECO rigs with SP system are equipped with very powerful hydraulic rotary tables that are sliding along the drilling mast of the unit by means of a high performance winch capable to develop very high crowd and extraction force.

A long single stroke drilling rod with hollow passage is attached at the bottom of the rotary to drive a special tool designed to lateral displace the soil of the drilled spot.

By drilling and crowding, the rod and the tool are penetrating the soil up to the designed drilling depth; concrete is the pumped through the hollow steam of the drilling road to be released at the bottom of the tool by means of an opening cap. During concrete pumping operation, the drilling rod with the tool is withdraw.
A steel reinforcement cage is them installed if required, by means of an auxiliary vibrator.
Soil displacement piles can be also performed with the LB (Lost bit) technique: in this case the reinforcement cage is installed inside the hollow steam of the drilling rod before concreting. After concreting the steel cage and the concrete are released at the bottom of the displaced pile by releasing the bottom of the tool that is left inside the pile.
A specially designed tool can be also provided to perform MF soil displacement piles: this system is based on the displacement of the soil to design a screw flight profile in the soil. By this system the friction of the soil with the concrete is increased.

Application field:
- Mud, clay and sand, loose or medium dense formations.
- Possibility to socket into fractured rock


Features:
- No material disposal with no material disposal costs, ideal for polluted sites
- Faster production compared to kelly auger piles
- No fluids to sustain the pile are required
- No vibrations or noise produced
- Full control of executed pile features by means of electronic devices
- Data recording of the pile and graphic rendering
