High-position construction method for cast-in-situ bored pile
The invention relates to a high-position construction method for a cast-in-situ bored pile, which comprises the following steps of: 1, positioning a pile foundation in water and a bridge beam plate to be dismantled, and analyzing surrounding environment and site conditions; 2, dismounting a ground bridge to-be-drawn and replaced T-shaped beam; thirdly, a pile machine operation platform is designed; fourthly, a pile foundation operation platform is erected; fifthly, a cast-in-situ bored pile machine is in place, and the underwater cast-in-situ pile of the viaduct is subjected to high And 6, a pile machine operation platform is dismantled, and other piers are erected at the ground bridge for platform construction. The construction operation space of the cast-in-situ bored pile in the navigation channel is created under the limitation of the space condition and the surrounding environment, and the influence of obstacles on the setting problem of the construction cast-in-situ bored pile foundation operation platform is effectively solved; and meanwhile, the common quality problems such as hole collapse frequently occurring in the construction of the cast-in-situ bored pile are reduced to the maximum extent by embedding the ultra-long pile casing on the high-position platform. The principle is simple, the construction method is safe and reliable, and the application effect is good.
本发明涉及一种钻孔灌注桩高位施工方法，步骤一：水中桩基与拟拆除桥梁梁板位置定位，周边环境、场地条件分析；步骤二：地面桥拟抽换T梁拆除；步骤三：桩机操作平台设计；步骤四：桩基作业平台搭设；步骤五：钻孔灌注桩桩机就位，高架桥水中灌注桩高位施工；步骤六：桩机操作平台拆除，其余墩位在地面桥处搭设平台施工。本发明在空间条件受限，周边环境制约下，创建航道水中钻孔灌注桩的施工操作空间，有效解决了障碍物对施工钻孔灌注桩桩基操作平台设置问题的影响，同时利用高位平台上埋设超长护筒最大限度地减少了钻孔灌注桩施工经常出现的塌孔等质量通病的发生。本申请原理简单，施工方法安全、可靠，应用效果好。
