Drop hammer type pile sinking device and pile sinking method thereof

Abstract

The invention discloses a drop hammer type pile sinking device, which comprises drop hammer guide frames and a sunken pile supporting frame, wherein the drop hammer guide frames are hoisted by a hoister; the top of an engineering pile is supported in a lower engineering pile supporting seat of each drop hammer guide frame; the sunken pile supporting frame comprises a plurality of steel tube piles; a polygonal section steel framework is fixedly connected with the steel tube piles; a plurality of guide frames are arranged on the polygonal section steel framework; and a plurality of engineering piles to be sunken are arranged in the guide frames. The invention also discloses a pile sinking method, which comprises the following steps of: 1) welding the polygonal section steel framework to the steel tube piles of the sunken pile supporting frame, and arranging a plurality of guide frames; and 2) respectively inserting a plurality of engineering piles into the corresponding guide frames, pressing the piles through the gravities of heads of power hammers or continuously hammering the tops of the engineering piles, and gradually finishing sinking the engineering piles one by one. The device has a simple structure and is convenient to manufacture and construct. The pile sinking method is low in cost and high in construction quality. The engineering piles are precisely positioned, and the construction efficiency is improved greatly.

Description

technical field [0001] The invention relates to an engineering pile construction facility for building a high pile beam-slab wharf, in particular to a pile sinking device and a pile sinking method for steel pipe piles or PHC piles (high-strength concrete pipes), belonging to the technical field of port engineering. Background technique [0002] When constructing high-piled girder-slab wharves and approach bridges on the riverside or coast, it is necessary to sink multiple engineering piles to the bottom of the river or seabed. Working platform and approach bridge deck. At present, the pile sinking construction method of domestic steel pipe piles or PHC piles on water generally adopts piling boat construction, and the construction cost is expensive. In addition, if the water depth and water area of ​​the piling barge cannot be satisfied, and the piling barge cannot move to the pile position, etc., the piling barge construction cannot be carried out.
