Fabricated wharf precast pile core bottom plugging device and construction method
The invention relates to the technical field of pile foundation construction, in particular to a prefabricated wharf precast pile core bottom plugging device and a construction method. Comprising a prefabricated pile core, a prefabricated pile cap and an air bag plugging structure, and the prefabricated pile core is of a reinforced concrete columnar structure inserted into a pile hole of a pile foundation; the precast pile cap is of a reinforced concrete structure poured at the top of the precast pile core; the air bag plugging structure comprises an air bag installed at the lower end of the prefabricated pile core. The air bag is of a structure which expands outwards to the side wall of the pile hole of the pile foundation to block the pile hole of the pile foundation under the condition that air is injected. The plugging device is simple in structure, the plugging construction method is easy and convenient to operate, the pile hole of the pile foundation can be rapidly plugged through the air bag, the plugging process is completely controllable, the plugging construction efficiency is improved, the construction difficulty is reduced, and great popularization value is achieved.
本发明涉及桩基施工技术领域，具体地指一种装配式码头预制桩芯底部封堵装置及施工方法。包括预制桩芯、预制桩帽和气囊封堵结构，所述预制桩芯是插入桩基桩孔内的钢筋混凝土柱状结构；所述预制桩帽是浇筑于预制桩芯顶部的钢筋混凝土结构；所述气囊封堵结构包括安装在预制桩芯下端的气囊；所述气囊是在注入空气情况下向外膨胀扩张至桩基桩孔侧壁对桩基桩孔进行封堵的结构。本申请的封堵装置结构简单，封堵施工方法操作简单方便，通过气囊能够对桩基桩孔进行快速的封堵，且该封堵过程是完全可控的，提高了封堵施工的效率，降低了施工难度，具有极大的推广价值。
