Construction method of TY-shaped composite pier
The invention discloses a construction method of a TY-shaped composite pier, and relates to the technical field of bridge construction. The construction method of the TY-shaped composite pier comprises the following steps that the TY-shaped composite pier is divided into a stand column type pier body part and a Y-shaped bent cap part; the pier body part is subjected to sectional cast-in-place construction by adopting a rollover method; bifurcate range steel bars are installed on the top of the pier body part, then Y-limb inclined leg range steel bars are installed on the bifurcate range steel bars, and concrete pouring is conducted on the bifurcate range steel bars; after concrete pouring is completed on the forked range steel bars, concrete pouring is conducted on the Y-limb inclined leg range steel bars; cross beam type range steel bars are installed on the tops of the Y-limb inclined leg range steel bars, and concrete pouring is conducted on the cross beam type range steel bars; and carrying out prestress tensioning on the reinforcing steel bars. According to the construction method, concrete can be filled compactly, bubbles are not prone to being generated, and only anti-corrosion and waterproof treatment needs to be conducted on a concrete outer wall, so that the structural strength of the TY-shaped composite pier can be improved through the construction method.
本发明公开了一种TY形复合墩的施工方法，涉及桥梁建设技术领域。该TY形复合墩的施工方法包括以下步骤：将TY形复合墩分为立柱式的墩身部和Y形的盖梁部；墩身部采用翻模法分节段现浇施工；在墩身部的顶部安装分叉范围钢筋，再将Y肢斜腿范围钢筋安装于分叉范围钢筋上，对分叉范围钢筋进行混凝土浇筑；待分叉范围钢筋进行混凝土浇筑完成后，再对Y肢斜腿范围钢筋进行混凝土浇筑；在Y肢斜腿范围钢筋的顶部安装横梁式范围钢筋，并对横梁式范围钢筋进行混凝土浇筑；进行钢筋预应力的张拉。本发明可使混凝土填充密实，不易产生气泡，针对于混凝土外墙只需做防腐、防水处理，因此该施工方法可提高TY形复合墩的结构强度。
