Walking type sliding incremental launching construction method and device for bridge construction
The invention provides a walking type sliding pushing construction method and device for bridge construction, and the method comprises the steps: arranging the walking type sliding pushing construction device for bridge construction and temporary construction bearing beams on buttresses, and splicing the temporary construction bearing beams; a longitudinal pushing hydraulic jack pushes the assembled temporary bearing beam to a walking type rolling deviation correction moving device; jacking a hydraulic jack to jack the assembled temporary bearing beam up the whole bridge, separating from the bearing beam, and supporting and transferring the bridge to a bridge assembling track by the bearing beam; the transverse deviation rectifying hydraulic jacks apply force synchronously to overcome the friction force of a walking type rolling belt on the walking type rolling deviation rectifying moving device, and the whole bridge moves forwards by the length of a piston; and the jacking hydraulic jack is controlled to shrink synchronously, and walking type sliding pushing construction of bridge construction with the length of one piston is completed. The device is simple in structure, small in working space, low in cost and particularly suitable for bridge steel beam pushing projects with large pushing working space.
本发明提供一种用于桥梁施工用步履式滑移顶推施工方法及装置，包括：在支墩上布置用于桥梁施工用步履式滑移顶推施工装置和施工临时垫梁，将施工临时垫梁拼装；纵向顶推液压千斤顶推动拼装好的临时垫梁至步履式滚动纠偏移动装置上；顶升液压千斤顶将拼装好的临时垫梁顶起整体桥梁，脱离垫梁，桥梁由垫梁支撑转移至桥梁拼装轨道上；横向纠偏液压千斤顶同步施力，克服所述步履式滚动纠偏移动装置上的步履式滚动带的摩擦力，桥梁整体前移一个活塞长度；控制顶升液压千斤顶同步缩缸，完成一个活塞长度的桥梁施工步履式滑移顶推施工。本发明结构简单，工作空间小，成本低，特别适用于顶推工作空间较大的桥梁钢梁顶推工程。
