Construction method of large-cantilever wing-spreading cast-in-place box girder
The invention discloses a construction method of a large-cantilever wing-spreading cast-in-place box girder, which is characterized in that a pipe core filling body and a pipe cavity ballasting body are arranged in a pipe cavity of a steel pipe pile, and a pipe periphery hardening body is arranged at the bottom end of the steel pipe pile; inclined supporting ribs are arranged on the pile top bearing platform, and a plate bottom solidified body is arranged on the lower portion of the pile top bearing platform; supporting steel pipes are arranged on the pile top bearing platform and the supporting transverse plate respectively, the built-in positioning rods and the pipe bottom positioning bodies are combined to control the perpendicularity and stability of the supporting steel pipes, and position control transverse ribs are arranged between the adjacent supporting steel pipes; the arrangement directions of the box girder inner die and the box girder outer die are controlled through the guide sliding grooves, and the inclination angles of the box girder bottom die and the flange bottom die are controlled through the plate bottom position control bodies, the adjustable supporting bags and the fixed supporting piers; an outer mold dense-mesh net and an inner mold dense-mesh net are arranged on the web plate outer mold and the inner mold bottom plate correspondingly, and a first pouring pipe and a second pouring pipe are combined for pouring concrete. The construction efficiency can be improved, the construction difficulty is reduced, and the construction quality is improved.
本发明公开了一种大悬臂展翅现浇箱梁施工方法，在钢管桩的管腔内设置了管芯填充体和管腔压重体，并在钢管桩的底端设置了管周硬化体；在桩顶承台上设置了斜向撑筋，在桩顶承台的下部设置了板底固化体；在桩顶承台和支撑横板上分别设置支撑钢管，并采用内置定位杆和管底定位体组合控制支撑钢管的竖直度和稳定性，在相邻的支撑钢管之间设置了控位横筋；通过导向滑槽控制箱梁内模和箱梁外模的布设方向，并采用板底控位体、可调撑袋和固定撑墩控制箱梁底模和翼缘底模的倾斜角度；在腹板外模和内模底板上分别设置了外模密目网和内模密目网，并采用第一灌注管和第二灌注管组合灌注混凝土。本发明可提升施工效率、降低施工难度、改善施工质量。
