Whole pushing equipment and method for wide-section steel box girder crossing expressway
The invention belongs to the technical field of steel box girder construction, and particularly relates to an overall pushing device and method for a wide-section steel box girder crossing an expressway, the overall pushing device comprises a base, a pushing deviation rectifying mechanism is arranged on the upper surface of the base, the pushing deviation rectifying mechanism comprises a fixing block, and swinging contact is conducted through the pushing deviation rectifying mechanism; the contact and friction between the steel box girder and the bottom of the steel box girder are increased, and deviation rectifying motion is conducted on the deviated steel box girder. According to the overall pushing equipment and method for the wide-section steel box girder crossing the expressway, by arranging the pushing deviation rectifying mechanism, when the steel box girder is jacked up, a swing block drives a contact block to make contact with the bottom of the steel box girder, so that the contact area and friction force are increased, and the good limiting effect on deviation in the pushing process of the steel box girder is achieved.
本发明属于钢箱梁施工技术领域，尤其是一种跨越高速公路宽截面钢箱梁整体顶推设备及方法，包括底座，底座的上表面设置有顶推纠偏机构，顶推纠偏机构包括固定块，通过顶推纠偏机构进行摆动接触，使其增大与钢箱梁底部的接触和摩擦，并对偏移的钢箱梁进行纠偏运动。该跨越高速公路宽截面钢箱梁整体顶推设备及方法，通过设置顶推纠偏机构，起到在钢箱梁顶起时，通过摆动块带动接触块与钢箱梁底部接触，从而增加了接触面积和摩擦力，对钢箱梁顶推过程中的偏移有着较好的限制效果。
