Construction method of low-clearance road-crossing cast-in-place beam
The invention provides a construction method of a low-clearance road-crossing cast-in-place beam. The construction method comprises the following steps: modifying a construction scheme and a construction drawing according to a simulation construction process; construction is conducted according to the modified construction scheme and the modified construction drawing, concrete foundations are arranged on the two sides and the middle position of the road on the construction site, and the bottoms of a plurality of stand columns are pre-buried in the concrete foundations; bailey beams are installed on the tops of the stand columns through supporting beams, a plurality of first working beams are arranged on the Bailey beams according to the preset distance, and a second working beam is installed on each first working beam through double-nut threaded steel; supporting pieces are installed on the second working beam through connecting I-shaped steel so that the supporting pieces can form a beam pouring space below the first working beam, whether the beam pouring space is qualified or not is checked and accepted, if the beam pouring space is qualified, beam pouring construction is conducted on the beam pouring space, the space below the road-crossing bridge is saved, and the construction efficiency is improved. And the clearance height is increased to facilitate traffic.
本发明提供了一种低净空跨路现浇梁的施工方法，包括根据模拟施工的过程对所述施工方案及所述施工图纸进行修改；根据修改后的所述施工方案及所述施工图纸进行施工，在所述施工现场路的两侧及所述路中间位置设置混凝土基础，并将多根立柱的底部预埋于所述混凝土基础内；在所述立柱的顶部通过支撑梁安装贝雷梁，在所述贝雷梁上根据预设距离排列若干第一工作梁，每一所述第一工作梁上采用双螺母的螺纹钢安装第二工作梁；在所述第二工作梁上通过连接工字钢安装有支撑件，以使所述支撑件在所述第一工作梁的下方形成浇梁空间，验收所述浇梁空间是否合格，若所述浇梁空间合格，则在所述浇梁空间上进行浇梁施工，节约了跨路桥梁下方空间，提高净空高度便于通车。
