Construction method of annular overbridge main beam at crossroad
The invention discloses a construction method for a main beam of an annular overpass at a crossroad. The construction method comprises the following steps: respectively pouring at least two pier studs on a sidewalk between two adjacent lanes; temporary supports are erected in the middle of three lanes, and dividing and blanking of main beam sections are conducted on an annular overbridge main beam; a first main beam section is installed on a sidewalk on one side of a lane without a temporary support, all pier studs on the sidewalk at the position are used for supporting the first main beam section, other main beam sections are installed in sequence, one end of the main beam section is fixedly connected with the corresponding previous main beam section, and the other end of the main beam section is fixedly connected with the other main beam section. And the other end of the main beam section is overhung on the outer side of the pier column or the temporary support supported below the main beam section, the tail main beam section is installed until supporting installation of the main beam section corresponding to the last pier column is completed, and the two ends of the tail main beam section are fixedly connected with the end of the previous main beam section and the end of the first main beam section respectively. The number of temporary supports is reduced, and normal passing of pedestrians and vehicles during construction is guaranteed.
本发明公开了一种十字交叉路口环形天桥主梁的施工方法，分别在相邻两条车道之间的人行道上浇筑至少两个墩柱；在其中三条车道的车道中间架设临时支架，对环形天桥主梁进行主梁节段的划分下料；在没有临时支架的车道一侧的人行道上安装首节主梁节段，该位置人行道上的所有墩柱用于对首节主梁节段进行支撑，依次安装其余主梁节段，该节主梁节段的一端与其对应的上一节主梁节段固定连接，另一端悬挑在其下方支撑的墩柱或临时支架的外侧，直至完成最后一个墩柱对应的主梁节段的支撑安装后，安装末节主梁节段，末节主梁节段的两端分别与上一节主梁节段和首节主梁节段的端部固定连接。本发明减少了临时支架的数量，保证了施工期间行人及车辆的正常通行。
