Crawler-type incremental launching construction equipment and construction method

The invention belongs to the technical field of bridge buildings, and particularly relates to crawler-type incremental launching construction equipment and a construction method, which can reduce the rising and falling times of a main beam in incremental launching construction and reduce the safety risk in the incremental launching construction. The main beam can be pushed in place at a time, and the pushing construction progress is accelerated; the main beam can be rectified by adjusting the speed of the driving mechanisms on the two sides; power equipment can be saved, the main beam is driven to advance through a small amount of power equipment, other positions are supported and assisted by the slideways, and the construction economic cost is saved. 本发明属于桥梁建筑技术领域，尤其涉及一种履带式顶推施工设备与施工方法，本发明可以减少顶推施工中主梁的起落次数，降低顶推施工中的安全风险；可一次性将主梁顶推到位，加快顶推施工进度；可通过调节两侧驱动机构的速度对主梁进行纠偏；可节省动力设备，通过少量动力设备带动主梁前进，其余位置使用滑道支撑辅助，节省施工经济成本。
