新型抱箍模具在浅海近滩栈桥施工中的应用

The Application of New Hoop Formwork in Construction of Offshore Shoal Trestle

在近海浅滩栈桥施工中,为解决落地架立杆落入松软地基而造成模板支架下沉的问题,利用新型抱箍模具与已完工的灌注桩抱紧,作为模板支撑体系,起到了替换落地支撑架的作用。结果表明,抱箍吊模施工方法受台风影响小,可避免钢制构件受海水的侵蚀,并能大大提高浅海边搭设模板支架的安全性与经济性,具有广泛的推广价值。

In the construction of offshore shoal trestle,in order to solve the problem of the sinking of formwork support caused by the landing frame pole falling into the soft foundation,the new hoop formwork is used to hold the completed cast-in-place pile tightly as the formwork support system,which plays the role of replacing the landing support frame.The results show that the construction method of hoop formwork is less affected by typhoon.It can avoid the corrosion of steel components by sea water,and can greatly improve the safety and economy of the formwork support erected on the shallow sea,which has a wide promotion value.
