Construction method of long spiral drilling micro steel pipe secant pile
The invention discloses a construction method of a long spiral drilling miniature steel pipe secant pile. The construction method comprises the following steps that firstly, a site is leveled; step 2, surveying and setting out; and 3, a pile jumping construction mode is adopted, lofting is conducted firstly, the plain cement piles (1) are constructed, after construction of the plain cement piles (1) is completed, control points are rechecked again, lofting is conducted, the meat piles (2) are constructed, and the plain cement piles (1) and the meat piles (2) form secant piles. The problems that in the prior art, the construction efficiency is low, the structural rigidity is low, and the water stopping performance is poor can be solved.
本发明公开了一种长螺旋钻孔微型钢管咬合桩的施工方法，包括以下步骤：步骤1：平整场地；步骤2：测量放线；步骤3：采取“跳桩”施工的方式，先放样并施工素水泥桩(1)，素水泥桩(1)施工完成后，重新复核控制点放样并施工荤桩(2)，素水泥桩(1)与荤桩(2)形成咬合桩。本发明能够解决现有技术中施工效率低、结构刚度较低、止水性能较弱的问题。
