导向架施工栈桥工法(国外英文资料) Assembly type cantilever guide frame construction trestle works Second engineering co., LTD One, foreword Suzhou long pier is located in the hangzhou bay sea-crossing bridge coast waters south beach area, extend from land to sea, the total length of 9.78 kilometers, is the suzhou cross-sea bridge, Ⅸ Ⅸ - A - B two blocks anti-washing construction of life channel, also is the worlds longest bridge construction. This bridge is designed by China railway group corporation. Hangzhou bay waters engineering geology is given priority to with silt clay, belongs to shallow sea semidiurnal tide sea area, tidal range is bigger, the rise time is long, large flow rate, the tide pier short effective time, steel pipe pile foundation construction and construction difficulty. Construction design and production of the fabricated cantilever guide frame fixing the pier foundation steel pipe piles, using the 80 t crawler crane with vibration hammer vibrating construction, successfully solved the sea pier construction problem, the formation of this method were summarized. The characteristics and scope of the work law Construction is not affected by the tide; Fast construction speed and ensure the accuracy and verticality of the pile. Operate platform with cantilevered guide frame, the personnel operation is safe and reliable. The vibration hammer vibrates the pile of steel pipe faster and sinks easily. Group of berley main girder, rear division block, front integral crane erection; Orthogonal cross-bridge panel modular construction, standardized operation. This method is suitable for the construction of piers in the area of haiti-beach area, cross river and sea. Third, the process principle Settled by using principles and bailey beam shear capacity, strong designed fabricated cantilever guide frame construction trestle steel pipe pile foundation, the orientation of water into land. Using all kinds of steel bailey truss girder and bridge deck module parts are connected in
