Bridge engineering construction method
The invention discloses a bridge engineering construction method which comprises the following steps that S1 longitudinal and transverse center lines of a pier foundation and a platform foundation are measured by using a theodolite, and excavating is carried out according to excavation depth, soil texture and water seepage conditions; S2 supporting frames are arranged along the two sides of a road, the distance between every two adjacent supporting frames is 5 to 8 m, a protection plate is arranged between the two supporting frames, the two sides of the protection plate are fixed to the supporting frames, and a warning tape is arranged on the outer side of the protection plate; S3 according to a design drawing, the theodolite is used for accurately positioning a pile position, a rotary drilling machine is used for drilling, a pile body is driven in after drilling, a lower bearing platform and an upper bearing platform are sequentially poured on the pile body, and a pier column is poured on the upper bearing platform; and S4 hollow slabs are prepared according to needs, prestress testing is carried out, the hollow slabs are hoisted, a scaffold is built, continuous correction is carried out in the building process, a support and a beam formwork are installed, and layered pouring and continuous pouring are carried out through concrete. The construction efficiency can be improved, and safe construction can be guaranteed.
本发明公开了一种桥梁工程施工方法，包括以下步骤：S1：用经纬仪测出墩、台基础纵、横中心线，根据开挖深度、土质和渗水情况进行开挖；S2：沿公路的两侧设置支撑架，相邻两个支撑架之间的距离为5‑8m，在两个支撑架之间设置防护板，防护板的两侧与支撑架固定，在防护板的外侧警示带；S3：根据设计图纸用经纬仪进行桩位精准定位，利用旋转钻机进行钻孔，钻孔后打入桩体，在桩体上方依次浇注下承台、上承台，在上承台上浇注墩柱；S4：按需制备空心板，并进行预应力测试，并对空心板进行吊装，搭建脚手架，搭建过程不断校正，安装支架和梁模板，利用混凝土进行分层浇筑和连续浇筑。本发明有助于提高施工效率，能够保证安全施工。
