Embodiment Construction

[0018] figure 1 A pile guide 10 embodying the invention is shown. The pile guide 10 includes a base frame 12 having a continuous, planar ground-engaging surface 14 and a pile guide member 16 configured such that when a pile (not shown) is driven into the ground 18, the The pile guides the pile (not shown) in a predetermined direction (arrow A) relative to the formation. The pile guide 16 is mounted on the base frame 12 by four support members 20 extending between the pile guide and the base frame 12 . Each support member 20 has an adjustable length, and the adjustment of the length enables a change in a predetermined direction relative to the planar formation joint surface 14 of the base frame 12 .

[0019] figure 2 , 3, and 4 show the structure of the length-adjustable support member 20 in more detail. Each adjustable length support member 20 includes a joint fitting 30 having a first part or fitting 32 connected to the base frame 12 and a second part connected to the pi...

Abstract

A pile guide (10) for supporting a pile as it is driven into a substrate, comprising: a base frame (12) having a planar substrate-engaging surface (14) and a pile guide member (16) configured to guide a pile in a predetermined direction therethrough as it is driven into a substrate (18), the pile guide member (16) being mounted on the base frame (12) via a plurality of support members (20) extending therebetween; characterised in that at least one of the plurality of support members (20) has an adjustable length, with length adjustment of the or each support member (20) enabling the predetermined direction to be varied relative to the planar substrate-engaging surface (14) of the base frame (12).

Description

technical field [0001] The present invention relates to methods and apparatus for driving piles into ground, particularly but not limited to uneven or undulating underwater ground with local level variations. Background technique [0002] It is known to provide pile guides for underwater piling, see for example W099 / 11872 (rapid frame pile guide), WO01 / 92645 (finned frame / driven pile guide), WO03 / 074795 (directional control pile guide) , and the Sea Steel Limited class of pile guides described in WO2009 / 024739 (Inclined frame pile guides). However, such pile guides are not ideal for driving piles into uneven or undulating underwater formations with local level variations. This is because such underwater formations tend to support the pile guides in different locations and at different angles to horizontal, which can result in piles being driven into the formation in different, non-vertical orientations. The present invention aims to solve such difficulties. Contents of t...
