Continuous girder erection construction method of 900t bridge girder erection machine low-position underpass gate-type pier
The invention discloses a continuous girder erection construction method for a 900t bridge girder erection machine low-position downward-penetrating gate-type pier. The continuous girder erection construction method comprises the steps that S101, a girder transporting vehicle is withdrawn; s102, reducing the carrying height of the beam transporting vehicle; s103, reducing the width of the bridge girder erection machine; s104, enabling the whole machine to pass through a gate-type pier in a low-position carrying posture; s105, front supporting legs of the bridge girder erection machine are erected; s106, a rear supporting leg of the bridge girder erection machine; s107, the bridge girder erection machine installs the dismantled parts; s108, self-erecting of the bridge girder erection machine; and S109, hole passing of the bridge girder erection machine. The bridge girder erection machine has the advantages that the newly-manufactured front carrying frame and the newly-manufactured rear carrying frame are additionally arranged on the bridge girder erection machine, the width and the height of the whole machine are reduced, the width of the bridge girder erection machine is recovered after underneath pass, the problem that the bridge girder erection machine difficultly passes through a gate-type pier on a construction site is solved, the height of the whole machine is effectively guaranteed when the bridge girder erection machine passes through the gate-type pier, non-transition continuous operation of the bridge girder erection machine is achieved, and the construction efficiency is improved. Operation steps are simplified, construction is convenient and fast, and construction efficiency is greatly improved.
本发明公开了一种900t架桥机低位下穿门式墩的连续架梁施工方法,S101、运梁车撤出;S102、降低运梁车的驮运高度;S103、减少架桥机的宽度;S104、整机以低位驮运姿态下穿门式墩;S105、架桥机的前支腿支立;S106、架桥机的后支腿;S107、架桥机安装已拆除部件;S108、架桥机自支立;S109、架桥机过孔。本发明的有益效果为:在运梁车上增加了新制的前驮架和后驮架,降低了整机的宽度和高度,下穿后再恢复架桥机的宽度,解决了施工现场架桥机通过门式墩困难的问题,有效保证了通过门式墩时整机的高度,实现了架桥机不转场连续作业,简化了操作步骤,施工方便快捷,大幅提升了施工效率。
