Construction method

Soil-Cement Injected Pre-casting Pile

When boring with augers, the original ground is strengthened by injecting cement paste, so the strength of surrounding strata increases after casting cement, greatly improving frictional force around steel piles. In addition, strengthened soil cement is completely filled in the fore-end, minimizing the settlement period of time for steel piles.

Features
This method concerns boring the ground with a screw using an earth auger, injecting excavation liquid and cement milk that is a fixing agent, inserting steel piles and finishing by conducting final light blows using a drop hammer.
Advantages
  • This method causes little noise or vibration, so there are few complaints from residents.
  • he surrounding frictional force can be easily secured by injecting cement milk.
  • As the agitation of the fore-end is achieved made with the injection of cement milk at the same time, the strength of the fore-end can be improved.
  • Bearing layers can be identified by the sand after a soil removal work.
