Steel pipe pile guide hole construction method under geological condition of inclined rock surface in water
The invention relates to a steel pipe pile guide hole construction method under the geological condition of an inclined rock surface in water. The steel pipe pile guide hole construction method under the geological condition of the inclined rock surface in water comprises the following steps that a spiral positioning drill rod is additionally arranged in front of a drill bit; a spiral positioning drill rod is drilled into the rock surface to drive a drill bit to drill downwards to a preset distance to form a drilling platform covering the target drilling hole site; after the drilling platform is formed, a drill bit is selected to drill and form a hole in the drilling platform; steel pipe piles are driven, and concrete is poured. By additionally arranging the spiral positioning drill rod on the drill bit, the spiral positioning drill rod can play a role in positioning the drill bit during drilling, so that the drill bit is prevented from sliding, the drill bit can drill smoothly to form the drilling platform, and the accuracy of the drilling position can be ensured by drilling holes in the drilling platform subsequently. When the inclination angle of the rock surface is too large, the drilling platform is formed in batches to reduce the sliding displacement of the spiral positioning drill rod as much as possible, and it is ensured that the drilling platform can cover the target drilling hole position.
本发明涉及一种水中斜岩面地质条件下钢管桩引孔施工方法，该水中斜岩面地质条件下钢管桩引孔施工方法包括如下步骤：在钻头前方加装螺旋定位钻杆；将螺旋定位钻杆钻入岩面以带动钻头下钻至预设距离形成覆盖目标钻孔孔位的钻孔平台；形成钻孔平台后，选用钻头在钻孔平台上钻进成孔；打设钢管桩并浇筑混凝土。通过在钻头上加装螺旋定位钻杆，在钻进时，螺旋定位钻杆能够起到定位钻头的作用，从而避免钻头滑动，使得钻头顺利进行钻孔形成钻孔平台，进而后续在钻孔平台上钻进成孔能够确保钻孔位置的准确性。在岩面倾斜角度过大时，通过分次形成钻孔平台以尽可能的减小螺旋定位钻杆的滑动位移，确保钻孔平台能够覆盖目标钻孔孔位。
