Construction method for controlling perpendicularity of sea-filled stratum casing secant pile
The invention provides a construction method for controlling the perpendicularity of a sea-filled stratum casing secant pile. The method comprises the following steps of leveling a site, measuring a positioning guide wall, installing an universal platform and a full-casing full-slewing drilling machine, installing a first section of a casing, arranging a clinometer on the first section of the casing for detecting the perpendicularity of the drilling angle of the first section of the casing, meanwhile, arranging two theodolites perpendicular to each other in direction used for monitoring the perpendicularity of the universal platform, the full-casing full-slewing drilling machine and the first section of the casing in the construction process, using a rotary drilling machine to break obstacles when encountering the obstacles, alternately using the theodolites and the full-casing full-slewing drilling machine till drilling is completed, finally, conducting hole cleaning and concrete pouring, and completing construction of the secant pile. According to the construction method, the perpendicularity of the construction process of the universal platform, the full-casing full-slewing drilling machine and the casing can be monitored in real time, and the drilling efficiency and the perpendicularity control precision of the full-casing full-slewing drilling machine are improved.
本发明提供一种填海地层套管咬合桩垂直度控制的施工方法，包括以下步骤：首先平整场地，测量定位导墙，安装好万能平台、全套管全回转钻机，然后安装第一节套管，并在第一节套管上设置倾斜仪，用于检测第一节套管钻进角度的垂直度，同时设置两台方向相互垂直的经纬仪，用于对万能平台、全套管全回转钻机和第一节套管在施工过程中的垂直度进行监测，在遇到障碍时可以采用旋挖钻机破除障碍，与全套管全回转钻机交替使用，直至完成钻孔，最后进行清孔和浇筑混凝土，完成咬合桩的施工。本发明能够对万能平台、全套管全回转钻机和套管的施工过程进行垂直度的实时监控，提高了全套管全回转钻机的钻孔效率和垂直度控制精度。
