我局一处在某船排基础工程的施工中成功地在潮差大、水深的情况下,采用了内外护筒,用贝雷架组拼民船作为浮动平台,用潜水电钻进行钻孔灌注桩施工。桩长12～13米,桩径φ60厘米,潮差约2米,最大水深约9米,共成桩58根,经过单桩承载试验,达到设计要求。其主要优点:施工机械简单, I Bureau of a ship in the construction of a row of boats in the successful construction of the tidal range, the depth of the case, the use of both inside and outside the shell, with the Balei group fighter fight floating platform for the use of submersible drill for bored piles construction. Pile length of 12 to 13 meters, diameter 60 cm, tidal range of about 2 meters, the maximum water depth of about 9 meters, a total of 58 pile into the pile, after single pile bearing test to meet the design requirements. Its main advantages: construction machinery is simple,
