Box culvert jacking construction distributive girder
The invention discloses a box culvert jacking construction distributive girder, which comprises large longitudinal beams, a distribution beam, limiting holes, limiting bolts, nuts, a box culvert, a sliding fulcrum, a jacking foundation stone, a jack, a reaction wall and temporary supporting columns. The large longitudinal beams are arranged on the distribution beam, the section of the distributionbeam is H-shaped, the limiting holes are formed in the bottom of two sides of the distribution beam, the limiting bolts are arranged on the distribution beam, and penetrate through the limiting holes, the nuts are arranged at the tail ends of the limiting bolts, the box culvert is arranged on one side of the distribution beam and located on the jacking foundation stone, the jack is arranged on the rear side of the box culvert, the reaction wall is arranged at the tail end of the jack, the sliding fulcrum is arranged between the box culvert and the distribution beam, the temporary supporting columns are arranged at the bottom of the distribution beam, and a running rail is arranged on the distribution beam. The box culvert jacking construction distributive girder has the advantages that: the temporary supporting columns translate in the construction jacking direction, the box culvert is jacked step by step, the temporary supporting columns are guided to be separated from the distribution beam so as to be dismounted, the situation that due to direct dismounting, the upper side running rail loses supporting force and deforms downwards is avoided, and time-saving and labor-saving boxculvert jacking is guaranteed.
箱涵顶进施工分配梁，包括大纵梁、分配梁、限位孔、限位螺栓、螺母、箱涵、滑动支点、顶进基石、千斤顶、反力墙、临时支柱，分配梁上设有大纵梁，分配梁截面为H型，分配梁两侧底部设有限位孔，分配梁上设有限位螺栓，限位螺栓穿过限位孔，限位螺栓尾端设有螺母，分配梁一侧设有箱涵，箱涵位于顶进基石上，箱涵后侧设有千斤顶，千斤顶尾端设有反力墙，箱涵与分配梁之间设有滑动支点，分配梁底部设有临时支柱，分配梁上侧设有运行轨道。本发明的优点在于：使临时支柱沿施工顶进的方向进行平移，使箱涵逐步顶进，临时支柱指导脱离出分配梁处再进行拆除，避免了直接拆除造成上侧运行轨道失去支撑力而向下发生形变的情况，保证箱涵顶进省时省力。
