Permanent and temporary combined deepwater bridge high pile cap construction method
The invention relates to a permanent and temporary combined deepwater bridge high pile cap construction method. The method comprises the following construction steps: S1, constructing a temporary fixed platform; and S2, construction of a second steel hanging box platform. And S3, dismantling the temporary fixed platform. And S4, the first steel hanging box platform is constructed. And S5, connecting the steel hanging box platform. And S6, cast-in-place pile construction. And S7, bottom sealing concrete is poured. And S8, bearing platform construction. And S9, ancillary facilities are constructed. The bridge permanent steel casing and the steel hanging box cofferdam are divided into two parts, a permanent structure is used as a temporary construction fixing platform for turnover in the construction process, so that construction of a bridge pile foundation and a bearing platform is conducted on the fixing platform, accurate positioning of the bridge permanent steel casing is guaranteed, and the construction efficiency is improved. And a large amount of temporary structural steel for a conventional fixed starting platform is avoided, the construction process is simple and easy to implement, and the economical efficiency is good.
本发明是一种永临结合的深水桥梁高桩承台施工方法，包括以下施工步骤：S1.临时固定平台施工。S2.第二钢吊箱平台施工。S3.临时固定平台拆除。S4.第一钢吊箱平台施工。S5.钢吊箱平台连接。S6.灌注桩施工。S7.封底混凝土浇筑。S8.承台施工。S9.附属设施施工。本发明将桥梁永久钢护筒及钢吊箱围堰一分为二，利用永久结构作为施工过程中周转的临时施工固定平台，使得桥梁桩基、承台的施工均在固定平台上进行，既保证了桥梁永久钢护筒的精准定位，又避免了采用常规固定起始平台大量的临时结构用钢，施工过程简单易行，经济性好。
