Installation and construction method of detachable prefabricated pile platform integrated steel bearing platform
The invention discloses a construction method of a detachable pile and platform integrated steel bearing platform. The construction method comprises the following steps that a prefabricated support is composed of four steel pipe rings, horizontal braces and angle braces; the support is placed on the ground, steel pipe piles are driven into the ground along the steel pipe rings, reinforcing pipes are welded to the outer walls of the topmost portions of the steel pipe piles, and reserved holes are formed in the overlapping positions of the reinforcing pipes and the steel pipe piles; the preformed holes of the steel pipe pile and the connecting pipe are overlapped, a pin shaft is inserted, and the pin shaft is fixed through a pin clamping ring; the steel pipe piles are driven underground; the four steel pipe piles and the steel pipe columns are driven one by one, and the column tops are located at the same position; plugging steel plates are arranged at the upper parts of the columns, and ground anchors are arranged on the inner sides of the columns; anchor bars are inserted into the columns; tower crane bottom feet are installed and fixed; concrete is poured, and a tower crane is installed; after use, the tower is disassembled, and the steel pipe piles and columns are pulled out. The method is low in construction cost and does not affect the underground structure layout.
本发明公开了可拆卸式桩台一体钢承台施工方法，包括以下步骤：预制支架由四个钢管圈和水平撑和角撑；将支架放置在地面上，沿钢管圈向地下打入钢管桩，管桩最顶部外壁上焊接有加强管，加强管及钢管桩重叠处设预留孔；焊接在钢管柱下焊接的带预留孔的连接管插入钢管桩顶部：使钢管桩、连接管的预留孔重叠，插入销轴，并用销卡环固定；将钢管桩打入地下；逐根完成四根钢管桩和钢管柱的打入，柱顶在同一位置；随挖土设置多道柱间支撑，柱上部设封堵钢板，内侧设锚钉；柱内插入锚筋；安装固定塔吊底脚；浇筑砼、安装塔吊；使用完成后拆塔，并拔出钢管桩和柱。采用本方法施工成本低、不影响地下结构布局。
