Foundation Construction Platform Used In a Beach or Offshore Areas

Abstract

The invention relates to a foundation construction platform adapted for foundation construction in a beach or offshore areas. The platform comprises a platform body ( 1 ), outriggers ( 5 ) mounted on the bottom of the platform body ( 1 ), a first hoisting frame ( 11 ) and first slide rails ( 21 ) longitudinally disposed along the platform body ( 1 ), the first hoisting frame ( 11 ) having a first lifting member ( 31 ) attached to the first transverse beam ( 111 ) thereof and the first hoisting frame ( 11 ) being capable of sliding along the first slide rails ( 21 ). Without other auxiliary equipments, such as, a crane, the operations like removing or rotating a pile can be carried out to decrease the number of the auxiliary equipments on a foundation construction platform so as to reduce the operation cost of the foundation construction platform. The present invention also provides a foundation construction platform including above mentioned hoisting equipments.
