Steel arch bridge arch rib pushing process
The invention discloses a steel arch bridge arch rib pushing process which comprises the following steps: step 1, mounting temporary piers according to a design line shape of a steel arch bridge, and arranging splicing platforms between skewbacks on two sides and between the adjacent temporary piers; 2, hoisting a guide beam and a first section of steel arch rib to the splicing platform, and fixedly connecting the guide beam and the first section of steel arch rib into a whole on the splicing platform; thirdly, the first section of steel arch rib is pushed through pushing equipment till the next arch splicing state is achieved, and the steel arch ribs on the two sides are synchronously pushed; fourthly, the first section of steel arch rib is temporarily fixed, a second section of steel arch rib is installed, and the second section of steel arch rib is pushed through pushing equipment till the next arch splicing state is achieved; fifthly, the third step and the fourth step are repeated till the steel arch ribs are pushed to the middle of the steel arch bridge, the guide beams are dismantled, and pushing continues till the steel arch bridge is closed; sixthly, the line shape of the steel arch ribs is adjusted, and folding is completed. The construction technology is safe, reliable, economical and applicable, and the safety and efficiency of construction are improved.
本发明公开了一种钢拱桥拱肋顶推工艺，包括如下步骤：步骤一、按照钢拱桥设计线形安装临时墩，并在两侧拱座及相邻的临时墩之间均设置拼装平台；步骤二、将导梁和第一节钢拱肋吊装至拼装平台，并在拼装平台上固定连接为一体；步骤三、通过顶推设备顶推第一节钢拱肋直至到达下一个拼拱状态，两侧钢拱肋同步顶推；步骤四、临时固定第一节钢拱肋，安装第二节钢拱肋，通过顶推设备顶推第二节钢拱肋直至到达下一个拼拱状态；步骤五、重复上述步骤三和步骤四，直至钢拱肋顶推至钢拱桥中部，拆除导梁，继续顶推直至合拢状态；步骤六、调节钢拱肋线形，完成合拢。本发明为一种安全可靠、经济适用的施工工艺，提高了施工的安全性和高效性。
