Underwater tie beam prefabricating and mounting construction method
The invention relates to an underwater tie beam prefabricating and mounting construction method. The construction method comprises the steps: firstly, tie beam sections and pile foundations are constructed; secondly, a steel casing on the outer side of the pile foundation is arranged; thirdly, a notch of the pile foundation steel casing is cut; fourthly, the steel casing on the outer side is pulled out; fifthly, the tie beam sections are installed; sixthly, welding is conducted; and seventhly, beam-pile joint cast-in-place is conducted: specifically, concrete covering tie beam steel bars is poured into the pile foundation steel casings, and therefore, the tie beam sections and the pile foundations are connected together. The invention provides the underwater tie beam prefabricating and mounting construction method capable of performing construction without a cofferdam, the problem that an existing underwater tie beam needs to be constructed by the cofferdam is solved, and a new methodfor constructing the underwater tie beam is provided.
本发明涉及一种水中系梁预制安装施工方法，第一步、系梁节段和桩基施工；第二步、桩基外侧钢护筒打设；第三步、桩基钢护筒槽口切割；第四步、外侧钢护筒拔除；第五步、系梁节段安装；第六步、焊接；第七步、梁桩接合部现浇：在桩基钢护筒内浇注掩盖住系梁部钢筋的混凝土从而将系梁节段同桩基连接在一起。本发明提供了一种无需围堰即能够进行施工的水中系梁预制安装施工方法，解决了现有水中系梁需要围堰进行施工的问题、提供了水中系梁施工的一种新方法。
