High-standard side-span cast-in-place beam refined construction technology
The invention relates to the technical field of cast-in-place beam construction, and provides a high-standard side-span cast-in-place beam refined construction technology which comprises the following steps of steel pipe pile foundation construction, support and support erection, formwork installation, preloading and settlement observation, steel bar and prestress installation, steel-concrete combined section steel beam installation, cast-in-place beam cable guide pipe installation and concrete pouring and maintenance. Pre-stress construction and grouting construction are conducted, and the formwork support is dismantled. By means of the high-standard side-span cast-in-place beam construction technology, it can be guaranteed that the structure of the cast-in-place beam is stable, and beam body deformation and cracks are reduced; through refined construction, material waste and maintenance cost can be effectively reduced; the three-dimensional model is established by designing the size and the coordinates of the anchor points, the installation position is calculated, and the total station is adopted for accurate positioning on the template, so that the cable guide pipe installation position is accurate, the cable force bearing and transmitting effects are good, and the cable force is uniformly distributed.
本发明涉及现浇梁施工技术领域，提供了一种高标准边跨现浇梁精细化施工工艺，包括以下步骤：钢管桩基础施工，支架支座搭设，安装模板，堆载预压与沉降观测，安装钢筋与预应力，钢混结合段钢梁安装，现浇梁索导管安装，混凝土浇筑与养护，预应力施工及压浆施，模板支架拆除。本发明通过高标准边跨现浇梁施工工艺，能够确保现浇梁的结构稳定，减少梁体变形和裂缝的产生；通过精细化施工，可以有效减少材料浪费和维修费用；通过设计尺寸及锚点坐标建立三维模型，计算安装位置，并采用全站仪在模板上精准定位，具有索导管安装位置精确，承载索力和传递索力效果好以及索力均匀分布的优点。
