Construction method of variable cross-section hollow thin-wall rectangular pier
The invention discloses a construction method of a variable cross-section hollow thin-wall rectangular pier. The construction method comprises the following steps: S1, determining a construction scheme of shortcut line selection, tower crane arrangement, steel bar outer frame and inner and outer mold processing, and concrete mixing and transportation; s2, four side lines of the pier column are accurately released according to the four corner points of the pier column, the outer frame is lifted and fixed through a tower crane, and steel bar connection and stirrup binding are carried out after safety and reliability are guaranteed. The construction technology can be used in cooperation with any section, operation is rapid and convenient, the outer frame and the inner frame do not need to be landed during construction, and the construction cost is reduced. A large amount of support cost and labor cost are saved, no special equipment is added, operation is easy and convenient, economical, practical, safe and reliable, the method is suitable for the hollow thin-wall square pier, the pier body is the variable cross section within 5 * 5 m, the higher the pier body is, the more economical, and therefore the technology is safe and reliable, operation is easy, the quality of constructed products is good, and the construction technology has high operability; the method has a wide application prospect and prominent social and economic benefits.
本发明公开了变截面空心薄壁矩形墩施工方法，包括以下步骤：S1.确定便道选线、布置塔吊、钢筋外架和内外模加工、砼拌制及运输的施工方案；S2.根据墩柱的四个角点精确放出墩柱的四条边线，用塔吊起吊外架并固定，保证安全可靠后进行钢筋连接和箍筋绑扎，本发明施工工艺可以在任何截面时配合使用，操作快捷方便，施工时不需要落地外架和内架，节省了大量的支架费用和人工费用，不增加任何特殊设备，操作简单方便，经济实用，安全可靠，适用于空心薄壁方墩，墩身为5*5米以内的变截面，墩身越高越经济，因此本发明工艺安全可靠，操作简单，施工的产品质量优良，施工工艺极具可操作性，有广阔的应用前景，社会、经济效益突出。
