Construction method for cleaning deepwater bed rock through cooperation of movable platform and rotary drilling rig
The invention provides a construction method for cleaning deepwater bed rock through cooperation of a movable platform and a rotary drilling rig. The construction method comprises the following steps that S1, a trestle is erected, and a slideway beam, the movable platform and the like are installed; s2, the rotary drilling rig moves to a movable platform, and trepanning is prepared; s3, the rotary drilling rig is used for drilling, an occlusion drilling mode is adopted, and the drilling sequence is a drill jumping method; s4, a traction system is started, and the movable platform is moved in the direction of the slide way beam; the traction system is fixed, the rotary drilling rig is operated, the step S3 is repeated, and construction of the row of secant piles is completed; and S5, starting the traction system to continuously move the platform, and repeating the steps S3 and S4 to complete the whole construction. The movable platform is matched with the rotary drilling rig, comprehensive dead-corner-free cleaning of deepwater bed rock within the bridge foundation range is achieved, on one hand, a blasting means is not needed, and the method is suitable for the environment where blasting cannot be conducted; on the other hand, the cofferdam does not need to be formed firstly, construction difficulty is reduced, construction efficiency is improved, and construction cost is saved.
本发明提供了一种可移动平台配合旋挖钻清理深水基岩的施工方法，步骤如下：S1、搭设支栈桥，安装滑道梁、可移动平台等；S2、旋挖钻机移动至可移动平台，准备开孔；S3、旋挖钻机钻进，采用咬合钻孔方式，钻进顺序为跳钻法；S4、启动牵引系统，将可移动平台沿滑道梁方向移动；固定牵引系统，操作旋挖钻机重复步骤S3，完成此排咬合桩施工；S5、启动牵引系统继续移动平台，重复步骤S3、S4，完成整个施工。本发明利用可移动平台配合旋挖钻机，实现桥梁基础范围内深水基岩全面无死角清理，一方面，无需使用爆破手段，适用于无法爆破环境；另一方面，无需先形成围堰，减小施工难度，提高施工效率，节约施工成本。
