Construction method applied to reverse construction steel pipe pile, and structure thereof
The invention relates to the technical field of steel pipe column reverse construction, and discloses a construction method applied to a reverse construction steel pipe pile. The construction method applied to the reverse construction steel pipe pile comprises the following steps of (1) pre-embedding a steel casing, and carrying out rotary drilling on a pile hole; (2) placing a concrete prefabrication platform, realizing the fixed connection of the concrete prefabrication platform and the steel casing through the detachable fixed connection of positioning lugs and positioning rods, and fixingthe concrete prefabrication platform on the ground through a group of positioning piles; (3) hoisting a pile foundation steel reinforcement cage into a hole bottom of the pile hole; (4) hoisting a steel pipe column into the pile hole; (5) installing a concrete pouring platform and a concrete guide pipe on the concrete prefabrication platform; (6) cleaning the pile hole by adopting a crossover-circulating type method; (7) adjusting an axial position, a central position and the perpendicularity of the steel pipe column; and (8) pouring concrete. The construction method applied to the reverse construction steel pipe pile provided by the invention has the effects of convenience in disassembling and installing of the reusable concrete prefabrication platform and the steel casing, and high construction efficiency.
本发明涉及钢管柱逆作施工的技术领域，公开了一种应用于逆作钢管桩的施工方法，包含以下步骤：步骤一，预埋钢护筒，旋挖桩孔；步骤二，放置混凝土预制平台，通过定位耳和定位杆的可拆卸式固定连接实现混凝土预制平台和钢护筒的固定连接，通过一组定位桩将混凝土预制平台固定在地面上；步骤三，将桩基钢筋笼吊入桩孔孔底；步骤四，将钢管柱吊入桩孔；步骤五，在混凝土预制平台上安装混凝土浇筑平台和混凝土导管；步骤六，采用反循环法清理桩孔；步骤七，调整钢管柱的轴向位置、中心位置以及垂直度；步骤八，混凝土浇筑。本发明具有可重复使用的混凝土预制平台和钢护筒拆安方便，施工效率高的效果。
