The invention discloses an abutment tower crane construction technology. The technology comprises the following steps that preparation is conducted on a construction site before installation; preparation before installation of the construction tower crane; pre-burying tower crane column feet; erecting a tower; the first step further comprises the steps that tower cranes are selected according to the maximum weight of a single component, and the number of the tower cranes is configured according to the number of the steel components; cleaning a site at a main tower at the water building side according to a construction plan, and providing conditions for temporary assembly and entry of parts; the invention relates to the technical field of abutment tower crane construction, in particular to a construction method for a main tower on the water building side. According to the pier tower crane construction technology, the problem of large-volume concrete pouring is solved, the problem of hydraulic pier reinforcing steel bar and formwork erecting is solved, a tower crane can conduct construction operation immediately after wind stop, the influence of maritime affairs and sea waves is small, when the tower crane works, the tower crane is straight up and down, the reinforcement cage mounting time is short, the construction progress is accelerated, and the construction cost is saved.

本发明公开了一种墩台塔吊施工工艺，包括以下步骤：施工现场的安装前准备；施工塔吊安装前的准备；塔吊柱脚预埋；立塔；拆除，所述第一步还包括：根据单根构件最大重量来选择塔吊，根据钢构件数量配置塔吊数量；根据施工计划在建水侧主塔处清理场地，为零部件的临时拼装进场提供条件；对建水侧主塔的作业场地进行合理规划，本发明涉及墩台塔吊施工技术领域。该墩台塔吊施工工艺，解决了大体积混凝土浇筑的难题，解决水工墩台钢筋、模板支立问题，塔吊在风停后能够立刻进行施工作业，受海事和海浪影响小，而塔吊作业时，直上直下，安装钢筋笼时间短，加快施工进度，节约施工成本。
