Bridge high pier hollow pier top sealing construction method
The invention discloses a closed construction method for a hollow pier top of a high bridge pier. The closed construction method comprises the following steps that S1, a bottom die is laid; when the top of the hollow pier is poured, a circle of steps with low inside and high outside are arranged at the top, base plates condensed with concrete are arranged at the two ends of the inner side of each step in the bridge direction, and a plurality of pieces of bottom die I-shaped steel stretching into the steps are horizontally arranged above the base plates on the two sides at intervals. The extending length of the bottom formwork I-shaped steel does not exceed the pier wall protection layer, a bottom formwork is arranged above the bottom formwork I-shaped steel, and the top face of the bottom formwork is flush with the outer side of the step; s2, pier top pouring; formworks on the side face of the pier top are firstly arranged, after all the formworks on the side face of the pier top are arranged, first-time pouring is conducted, the height of the first-time pouring is one third of the height of the whole pier top, and when the strength of concrete poured for the first time reaches 72%-78%, remaining sections are poured. The vertical bearing problem of pier top solid section construction is solved through the characteristics of high size specification and strength of the profile steel structure.
本发明公开了一种桥梁高墩空心墩顶封闭施工方法，包括以下步骤：S1：铺设底模；在空心墩的顶部浇筑时，顶部设置为一圈内低外高的台阶，在台阶内侧沿着桥梁方向的两端设置有与混凝土凝结在一起的垫板，在两侧的垫板上方水平间隔设置有若干根伸入到台阶内的底模工字钢，且底模工字钢的伸入长度不超过墩壁保护层，所述底模工字钢的上方设置有底模板，且底模板的顶面与台阶的外侧齐平；S2：墩顶浇筑；先设置墩顶侧面的模板，当墩顶侧面的模板全部布置完成后，再进行第一次浇筑，第一次浇筑的高度为整个墩顶高度三分之一，待第一次浇筑的混凝土强度达到72％‑78％时，浇筑剩余段。通过型钢结构尺寸规格及强度高的特点解决墩顶实心段施工竖向承重的问题。
