Pipe pile foundation construction process
The invention discloses a tubular pile foundation construction process which comprises the following steps: step 1, pile casing burying: a steel plate is adopted to roll a pile casing, backfill soil on the surface of the pile casing burying position is excavated, cohesive soil is rammed and filled to the position 0.5 m below the bottom of the pile casing, a lower opening is buried in sand clay by 1-2 m, and the top of the pile casing is 30-50 cm higher than the ground of an outlet opening; 2, drilling is conducted, specifically, a percussion drill is used for drilling; compared with a traditional pipe pile construction process, the pipe pile foundation construction process does not add a corresponding complex process, so that the pipe pile foundation construction process can be popularized in a large range, position deviation can be prevented through the pore-forming detection process and the reinforcement cage placing process, the reinforcement cage is more convenient to manufacture, and the construction cost is reduced. And the cushion block is arranged at the top of the reinforcement cage in the placing process, and the cushion block is attached to the inner wall of the pile casing, so that it can be guaranteed that the reinforcement cage cannot deviate when being placed.
本发明公开了一种管桩基础施工工艺，所述管桩基础施工工艺包括以下步骤：步骤一：护筒埋设：采用钢板卷制护筒，将护筒埋设位置表面的回填土进行挖除，夯填粘性土至护筒底部0.5m以下，下口埋入至沙黏土内1‑2m处，护筒顶部高于出孔口地面30‑50cm；步骤二：钻孔：利用冲击钻进行钻孔。本发明设置的管桩基础施工工艺与传统的管桩施工工艺并未增加相应的复杂过程，因此可以对其进行大范围推广，而设置的成孔检测以及钢筋笼安放过程可以防止出现位置偏差，而钢筋笼的制造更加方便，而且钢筋笼在安放的过程中在其顶部设置有垫块，而且垫块与护筒的内壁相贴合，从而可以保证钢筋笼安放的时候不会出现偏移。
