The invention belongs to the technical field of gate dam engineering, particularly relates to a gate dam engineering overhead construction process and a bridge girder erection machine, and aims to solve the problems that during hoisting and conveying, hoisting cables of the bridge girder erection machine are difficult to avoid being in contact with the surfaces of structural components during use, so that the hoisting cables are abraded after being used for a long time, potential safety hazards are caused, and the construction cost is lowered. At present, the following scheme is provided: a foundation pit excavation project is provided: mechanical excavation, layered excavation from top to bottom and step-by-step descending are adopted, and the stability of earth excavation needs to be paid attention to in the construction process. The gate dam project overhead construction technology and the bridge girder erection machine have the effect of improving the use safety effect of the device, and the device can protect the contact point part between a hoisting cable and a structural component during use, so that the structural component is prevented from being in direct contact with the hoisting cable in the hoisting process; abrasion of the hoisting cable is avoided, the service life of the device is prolonged, and the safety of the device is improved.

    本发明属于闸坝工程技术领域,尤其是一种闸坝工程凌空施工工艺及架桥机,针对在进行吊装输送时,架桥机的吊装线缆在使用时难以避免的会与结构部件表面接触,从而在长时间使用后以对吊装线缆造成磨损,造成安全隐患,且在使用时亦会对结构部件造成损伤,现提出以下方案,包括基坑开挖工程:采用机械开挖,自上而下分层开挖,逐级下降,在施工过程中要注意土方开挖的稳定性。本发明公开的一种闸坝工程凌空施工工艺及架桥机具有增加装置使用安全效果的作用,在进行使用时装置能够对吊装线缆与结构部件之间的接触点部位进行保护,从而在吊装过程中避免结构部件与吊装线缆直接接触,进而避免吊装线缆的磨损,增加装置的使用寿命与安全性。
