浅论桥梁灌注桩施工

Construction of Concrete Piles of Bridges

水下混凝土灌注桩技术现在已经被广泛应用在桥梁的施工当中。桥梁下部结构经常采用单桩单柱的结构形式,由于桩数较少,受力集中,负荷较大,桩身一旦发生严重缺陷很难采取补救措施,所以对大口径桥桩的成孔质量和灌注质量要求十分严格。

Underwater concrete piles have now been widely used in the construction of bridges.Single piles are often used in the lower part of bridges,with fewer piles with focused and greater load,which may result in serious defects that is difficult to remedy.Therefore,strict measures should be taken to control the pore-forming and casting qualities of large-diameter bridge piles.
