The invention relates to the field of foundation pit excavation, in particular to a safety protection device for a deep foundation pit excavation pithead of a tower. The technical problem that a protection mechanism is imperfect and unreasonable in existing foundation pit excavation work is solved. The pithead safety protection device for pole tower deep foundation pit excavation comprises a bucket unit, an air cushion protection unit and the like. And the inner lower side of the bucket unit is connected with an air cushion protection unit for protecting a constructor. The pit mouth supporting framework, the lifting device, the monitoring and rescuing system and the crawling ladder fixing device are arranged, when a constructor excavates a foundation pit, the gas detection system monitors the gas quality in real time, the life detection system detects the life state of the constructor in real time, and when danger occurs, the constructor quickly opens an escape air cushion in the lifesaving equipment, so that the safety of the constructor is improved. The constructor is rapidly taken away upwards by the lifting device to escape, a circle of fire-fighting dry powder is scattered around, toxic gas is pushed downwards to be rolled and settled, and escape time is won for the constructor.
本发明涉及基坑挖掘领域,尤其涉及一种杆塔深基坑开挖坑口安全防护装置。为了解决现有基坑挖掘工作存在防护机制不完善、不合理的技术问题。本发明提供了这样一种杆塔深基坑开挖坑口安全防护装置,包括有吊桶单元和气垫防护单元等;吊桶单元的内下侧连接有保护施工者的气垫防护单元。本发明设有坑口支撑骨架、提升装置、监测救援系统和爬梯固定装置,施工者在进行基坑挖掘工作同时,气体检测系统实时监测气体质量,生命探测系统对施工者的生命状态实时探测,当危险发生时,施工者快速打开救生设备中的逃生气垫,由提升装置快速将施工者向上带离逃脱,并向四周散放一圈消防干粉,将有毒气体向下推卷沉降,为施工者的争取逃生时间。
