一种挖孔桩孔口提升防护用装置
摘要：
本实用新型涉及超大直径人工挖孔桩领域，具体涉及一种挖孔桩孔口提升防护用装置。提升防护用装置包括可移动底座以及提升设备，提升设备设置在可移动底座上；挖孔桩孔口设置有滑道，可移动底座与滑道配合，并可沿着滑道滑动；在挖土施工的时候可移动底座沿着滑道向挖孔桩孔口的边沿方向滑动，挖孔桩孔口敞开，通过提升设备提升弃土，在停止挖土作业的时候，可移动底座沿着滑道向挖孔桩孔口的中间方向滑动，挖孔桩孔口封闭。该方案可解决提升设备的工作效率低的问题，以及在停止挖土作业的时候，容易从敞开的井口落入人员或其它物品而造成的安全问题。
摘要（英）：

The utility model relates to an artifical bored pile field of super large diameter, concretely relates to bored pile drill way promotes protection and uses device. Promoting the protection and including portable base and lifting means with the device, lifting means sets up on portable base, the bored pile drill way is provided with slide, portable base and slide cooperation to can slide along the slide, slide to the border direction in bored pile drill way along the slide at the portable base of cutting the earth in the construction, the bored pile drill way is opened, promotes the spoir through lifting means, and in the operation that stops to cut the earth, portable base seals to slip, bored pile drill way along the third side of slide to the bored pile drill way. Lifting means's the problem that work efficiency is low can be solved to this scheme to and in the operation that stops to cut the earth, fall into personnel or other article and the safety problem that causes from open well head easily.
