The invention relates to the field of well lids for tunnels, and discloses a tunnel built-in escape well lid which comprises a lid body, a protection mechanism is arranged at the lower end of the lid body, limiting mechanisms are arranged on the front side and the rear side of the lower end of the lid body, the protection mechanism is fixed to the lower end of the lid body through the limiting mechanisms, and the protection mechanism can extend downwards to achieve the protection effect. The protection mechanism is arranged, the protection mechanism can be detachably used for protecting a user when the user moves during escape, an existing tunnel built-in well lid can only play a role in preventing personnel or articles from falling into a well opening and preventing pollution, and when accidents such as fire disasters occur in the tunnel, the protection effect on escapers cannot be achieved; the protection mechanism can sleeve the head position of an escaper, the protection mechanism is automatically unfolded to be in a circular truncated cone shape through the weight of the balancing weight, the head and the body of the escaper can be protected, the escaper is prevented from being hurt by flames or rockfall and the like, and the escaper can conveniently move to leave a dangerous position.
本发明涉及隧道用井盖领域，且公开了一种隧道内置逃生井盖，包括盖体，所述盖体的下端设有保护机构，所述盖体下端的前后侧均设有限位机构，所述保护机构通过限位机构固定于盖体的下端，所述保护机构可向下延伸展开达到防护效果，本发明提供的具有保护机构，保护机构可拆卸使用对使用者逃生移动时进行防护，现有的隧道内置井盖只能起到防止人员或物品掉入井口及防污作用，当隧道内部发生火灾等此类意外情况时，无法对逃生者起到防护作用，本发明可以将保护机构套至逃生者头部位置，其通过配重块的重量自动展开呈圆台状，可以保护逃生者的头部及身体，防止其受到火苗或落石等伤害，便于逃生者移动离开危险位置。
