Construction method of single-tower wide cast-in-place box girder tower girder consolidation area
The invention relates to a construction method for a single-tower wide cast-in-place box girder tower girder consolidation area. The construction method comprises the following steps that an embedded hole is reserved in a bearing platform; the steel pipe stand columns are welded to the bearing platform, and then bottom formworks are laid on the steel pipe stand columns and the pier columns; a water bag fixing chessboard type steel frame is installed in a construction site; a top plate detachable rail laser ultrasonic double-system paving system is installed, and an I-shaped steel rail is arranged; and a wide cast-in-place box girder moving formwork is installed, and a cast-in-place box girder is poured on the top of the pier column. The construction method has the beneficial effects that the pre-buried holes are formed in the bearing platform, and the micro concave surfaces are arranged on the pre-buried steel plate groups in the pre-buried holes, so that the welding efficiency of the steel pipe piles and the pre-buried steel plate groups can be improved, a good supporting effect is achieved, and potential safety hazards of construction are reduced; the water bags are fixed through the water bag fixing chessboard type steel frame, the water bag fixing device has good applicability to a construction site with abundant water resources, and the chessboard type steel frame has high overall rigidity and can well fix the water bags at the same time.
本发明涉及一种独塔宽幅现浇箱梁塔梁固结区的施工方法，包括以下步骤：在承台上预留预埋孔；将钢管立柱焊接在承台上，随后在钢管立柱和墩柱上铺设底模板；在施工场地内安装水袋固定棋盘式钢框格；安装顶板可拆式轨道激光超声波双系统摊铺体系，设置工字钢轨道；安装宽幅现浇箱梁移动模架，在墩柱顶部浇筑现浇箱梁。本发明的有益效果是：通过在承台上施做有预埋孔，在预埋孔内的预埋钢板群设置有微凹面，可提高钢管桩和预埋钢板群的焊接效率，且具有良好的支撑效果，降低施工的安全隐患；通过水袋固定棋盘式钢框格固定水袋，对于水资源充沛的施工现场具有良好的适用性，棋盘式钢框架具有较强整体刚度的同时还可以较好地固定水袋。
