Composite structure old wharf reconstruction and extension construction method and structure
The invention provides a composite structure old wharf reconstruction and extension construction method and structure, and the construction method comprises the steps that breaking and leveling are carried out on the upper part of the rear end of a concrete square block of an old wharf, and a first groove is formed; a surface layer, a first filling layer and a vertical beam on the top of a middlepanel of the old wharf are dismantled to enable the middle panel of the old wharf to be flatly exposed; a plurality of through holes used for cast-in-place pile construction are formed in the middle panel of the old wharf, and cast-in-place piles are constructed at the positions corresponding to the through holes respectively; the middle panel of the old wharf is dismantled and an old wharf foundation pile below the middle panel of the old wharf is broken off; a newly-built wharf is built at the tops of the cast-in-place piles, a buffer plate is arranged between the front end of the newly-built wharf and the first groove, and a gap exists between the bottom of the newly-built wharf and the first groove; and retaining walls are built on the left side, the right side and the rear side of thenewly-built wharf respectively, and buffer plates are arranged between the retaining walls and the newly-built wharf. The composite structure old wharf reconstruction and extension construction method and structure aim to overcome the defects of an existing composite structure old wharf reconstruction and extension construction method.
本发明提供了一种混合结构旧码头改扩建施工方法及结构，其中施工方法包括对旧码头的混凝土方块的后端上部进行破除并找整平，形成第一凹槽；拆除旧码头中部面板顶部上的面层、第一填充层和立梁，以使旧码头的中部面板平整露出；在旧码头的中部面板上开设多个用于灌注桩施工的贯穿孔，在对应于每个贯穿孔的位置分别施工灌注桩；拆除旧码头的中部面板和折断旧码头中部面板下方的旧码头基桩；在灌注桩顶部建造新建码头，新建码头的前端与第一凹槽之间设置缓冲板，其底部与第一凹槽之间存在间隔；在新建码头左侧、右侧和后侧分别建造挡墙，挡墙与新建码头之间设置缓冲板。本发明旨在解决现有混合结构旧码头改扩建施工方法的不足。
