Walking type incremental launching construction method and system capable of actively controlling beam falling
The invention relates to a walking type incremental launching construction method and system capable of actively controlling beam falling, according to the method, translation of a main beam is jointly achieved through a large jack and small jacks arranged on the two sides of the large jack, the large jack is a slidable jack, and the method comprises the following steps that (1) the large jack is controlled to jack, and the small jacks are arranged on the two sides of the large jack; the main beam is independently supported; (2) the large jack is controlled to slide, and the main beam is driven to be horizontally pushed by one stroke; (3) the small jacks are controlled to jack and support the main beam, the large jacks are controlled to descend, and at the moment, the small jacks independently support the main beam; (4) controlling the large jack to slide and return, returning to the step (1), and starting the next reciprocating stroke; in the steps, the controller collects and records key data in the pushing cycle in real time. Compared with the prior art, the device has the advantages of high adjustment precision, good flexibility and maneuverability and the like.
本发明涉及一种落梁主动控制的步履式顶推施工方法及系统，所述方法通过大型千斤顶以及设置于所述大型千斤顶两侧的小型千斤顶共同实现主梁的平移，所述大型千斤顶为可滑移千斤顶，包括以下步骤：1)控制所述大型千斤顶顶升，独立支撑主梁；2)控制所述大型千斤顶滑移，带动所述主梁平推一个行程；3)控制所述小型千斤顶顶升支撑住主梁，并控制所述大型千斤顶下降，此时由所述小型千斤顶独立支撑主梁；4)控制所述大型千斤顶滑移回位，返回步骤1)，开始下一个往复行程；在上述各步骤中，控制器实时采集并记录顶推循环内的关键数据。与现有技术相比，本发明具有调整精度高，灵活性机动性好等优点。
