Deep foundation work completed on Hong Kong project

Duty cycle crawler cranes have recently helped complete deep foundation work for a housing project in Hong Kong.

The three Liebherr duty cycle crawler cranes helped with the installation of 14 piles. The first stage was carried out by two HS 885 HD machines and one HS 8130 HD, each fitted with a mechanical grab and an oscillator.

In order to achieve the necessary depth of 50m, the contractor required ten working days per pile due to the difficult ground conditions, such as groundwater followed by rock with a very high strength of 150 MPa.

To penetrate this hard layer, the RCD method was used. With a diameter of 3m, up to 300 m3 of concrete was required for the completion of each pile.

The deep foundation work took six months to complete.
