Integral moving construction method for cast-in-place segmental beam bottom die of arched beam combination bridge
The invention relates to the field of arched beam combination bridges, and discloses an arched beam combination bridge cast-in-place segment beam bottom die integral moving construction method which comprises the following steps: completing pier construction, pouring an upper chord arch 0 # section, pouring a lower chord arch by using a hanging basket in a segmented manner, erecting a bracket on the lower chord arch, erecting an upper chord template on the bracket, and erecting a lower chord template on the bracket. An upper chord beam is poured in a segmented mode through the upper chord formwork in a slip-form construction mode; the method for erecting the support and adopting slip-form construction comprises the steps that a1, the support is erected on the poured section of the lower chord arch, a plurality of small transverse rods are arranged at the top of the support, the small transverse rods are transversely arranged and longitudinally arranged on the support, a plurality of sliding rods are welded to the small transverse rods in the longitudinal direction, and an upper chord formwork is supported on the sliding rods in a sliding mode; a2, a sliding driving system is prepared, the sliding driving system is connected with the poured section of the upper chord beam, and the sliding driving system pushes the upper chord formwork to slide to the next section, to be poured, of the upper chord beam in the direction of the sliding rod; the construction speed of the upper chord beam is increased.
本发明涉及拱梁组合桥梁领域，公开了拱梁组合桥现浇节段梁底模整体移动施工方法，包括以下步骤：完成桥墩施工，浇筑上弦拱0#段，使用挂篮分段浇筑下弦拱，在下弦拱上搭设支架，在支架上搭设上弦模板，上弦模板采用滑模施工的方式分段浇筑上弦梁；搭设支架并采用滑模施工的方式为：步骤a1、在下弦拱已浇段上搭设支架，支架顶部设有若干小横杆，小横杆横向设置，若干小横杆纵向排列在支架上，小横杆上沿纵向焊有若干滑杆，上弦模板滑动支撑在滑杆上；步骤a2、准备滑动驱动系统，将滑动驱动系统和上弦梁的已浇段连接，滑动驱动系统推动上弦模板沿滑杆方向滑动至上弦梁待浇筑的下一节段；以加快上弦梁的施工速度。
