Bridge abutment type anchorage system and anchorage method

ZHAO LICAI / LIU SHENGJUN / WANG XUDONG

The invention relates to the technical field of bridge construction, in particular to a bridge abutment type anchorage system and method. The bridge deck type anchorage system comprises buried pipes, inhaul cables, distribution beams and steel supports. The buried pipe is obliquely arranged in the bridge abutment along a set angle, the first end and the second end of the buried pipe both penetrate through the bridge abutment and extend to the outside of the bridge abutment, and the first end of the buried pipe is lower than the second end of the buried pipe; the inhaul cable is arranged in the buried pipe, and one end of the inhaul cable penetrates through the first end of the buried pipe and is fixedly connected with the bridge abutment; the steel support is arranged at the second end of the buried pipe. According to the bridge abutment type anchorage system, the buried pipe can be reserved in the bridge abutment in advance when the bridge abutment is poured and can also be perforated and buried in the bridge abutment in the later period, one end of the inhaul cable penetrates through the buried pipe and is connected with the bridge abutment in an anchoring mode, the bridge abutment can serve as an anchoring foundation, the structure is reliable, an anchoring steel frame of a complex structure does not need to be independently built, and the construction cost is reduced. And the construction efficiency is greatly improved.

本公开涉及桥梁施工技术领域，尤其涉及一种桥台式锚碇系统以及锚碇方法。该桥台式锚碇系统包括：埋管、拉索、分配梁和钢支架；所述埋管沿设定角度倾斜设置在桥台内，所述埋管的第一端和第二端均贯穿所述桥台并延伸到所述桥台的外部，所述埋管的第一端低于其第二端的高度；所述拉索置于所述埋管内，所述拉索的一端穿过所述埋管的第一端并与所述桥台固定连接；所述钢支架设置在所述埋管的第二端。该桥台式锚碇系统，埋管可以在桥台浇筑时提前预留在桥台内，也可以后期打孔埋入到桥台内，拉索的一端穿过埋管并与桥台进行锚固连接，能够实现利用桥台本身作为锚固基础，不仅结构可靠，而且无需单独搭建一套结构复杂的锚固钢架，大大提高施工效率。
