Horizontal rotation construction method for steel truss girder bridge
The invention relates to the field of steel truss bridge construction technologies, and discloses a steel truss bridge horizontal rotation construction method which comprises the following steps: S1, lower bearing platform construction: pouring a foundation pile in a foundation pit, and then pouring a lower bearing platform on the foundation pile; s2, lower spherical hinge construction is conducted, specifically, a lower spherical hinge is erected on the lower bearing platform, a sliding way is erected on the peripheral side of the lower spherical hinge, and a pin shaft is arranged at the axis position of the lower spherical hinge in a penetrating mode; s3, upper spherical hinge construction is conducted, specifically, the upper spherical hinge is hoisted and aligned with the pin shaft, then the upper spherical hinge is placed on the lower spherical hinge, and the upper spherical hinge is inserted into the pin shaft; s4, an upper bearing platform is constructed, specifically, a jacking and supporting mechanism is arranged on the sliding way, a pouring formwork is erected on the jacking and supporting mechanism, then reinforced concrete is poured on the upper spherical hinge, and the upper bearing platform is formed; s5, bridge splicing; s6, steering the bridge; and S7, folding the bridge. Construction is conducted on one side of the river channel or the traffic lane, and the effects of reducing the possibility of influences caused by the river channel or the traffic lane and ensuring the traffic capacity of the river channel or the traffic lane are achieved.
本申请涉及钢桁架桥施工技术的领域，公开了一种钢桁架梁桥水平转体施工方法，其包括以下步骤：S1：下承台施工，在基坑内浇筑基桩，然后在基桩上浇筑下承台；S2：下球铰施工，在下承台上搭设下球铰，并在下球铰的周侧搭设滑道，在下球铰轴线位置穿设销轴；S3：上球铰施工，将上球铰吊起并与销轴对齐，然后将上球铰放置在下球铰上，并使上球铰插在销轴上；S4：上承台施工，在滑道上设置顶撑机构，并在顶撑机构上搭设浇筑模板，继而在上球铰上浇筑钢筋混凝土，形成上承台；S5：桥梁拼装；S6：桥梁转向；S7：桥梁合拢。本申请通过在河道或者行车道的一侧施工，具有降低河道或行车道造成影响的可能，保证河道或者行车道的通行能力的效果。
