摘要:
曹妃甸30万吨级原油码头桩基采用直径1.8 m钢管桩,桩长64.5~77 m,桩重81.37~94.51 t,桩重为目前国内之最。文章论述了打桩锤、打桩船的选择和打桩锤、打桩船的技术性能;钢管桩节点的布置及受力计算;以及沉桩施工步骤。经优化的沉桩工艺,使超长、超重钢管桩顺利施打完毕,施工质量达到优良水平。
Caofeidian Crude Oil Terminal for vessels up to 300 000 dwt is founded on steel tubular piles with a diameter of 1.8 m,lengths from 64.5 m to 77 m,and weights from 81.37 t to 94.51 t,which have been the heaviest so far in China.The paper describes the selection of the pile hammers and the floating pile drivers as well as the technical performance of the pile hammers and the floating pile drivers;arrangement of hoisting points on the steel tubular piles and stress calculations;and procedure for installation of the piles.The optimized technology for driving of the steel tubular piles facilitates the smooth completion of the installation of the steel tubular piles with ultra lengths and weights and the quality of pile installation came up to the level of excellence.
