The invention discloses a manhole with a fall-preventing function. The manhole with the fall-preventing function comprises a manhole wall. A circular groove is formed in the upper end of the manhole wall. A manhole cover is placed in the circular groove. First grooves are formed in the left end and right end of the circular groove. A first rotary shaft is arranged in one first groove. A first rotary rod is rotatably connected with the first rotary shaft. A first clamping column is arranged at the tail end of the first rotary rod. The first clamping column is installed in the first groove on the other side in an embedded manner. Second grooves are formed in the front end and rear end of the circular groove. A second rotary shaft is arranged in the second grooves. A second rotary rod is rotatably connected with the second rotary shaft. The second rotary rod and the first rotary rod are arranged in a perpendicular manner. A second clamping column is arranged at the tail end of the secondrotary rod. The second clamping column is installed in the second groove on the other side in an embedded manner. A lower clamping groove is formed in the lower end of the middle of the first rotary rod. An upper clamping groove matched with the lower clamping groove is formed in the upper end of the middle of the second rotary rod. According to the manhole with the fall-preventing function, the first rotary rod and the second rotary rod are arranged; through rotating the first rotary rod and second rotary rod, the first rotary rod and second rotary rod are placed in a cross manner and can play a supporting part for the manhole cover, and the manhole cover can be prevented from falling downwards; and safety of the manhole is improved.
本发明公开了一种带防坠功能的检查井，包括井壁，所述井壁上端设置有圆形凹槽，圆形凹槽内放置有井盖，所述圆形凹槽左右两端设置有凹槽一，凹槽一内设置有转轴一，转轴一转动连接有转杆一，转杆一末端设置有卡柱一，卡柱一嵌入安装在另一侧凹槽一内，所述圆形凹槽前后两端设置有凹槽二，凹槽二内设置有转轴二，转轴二转动连接有转杆二，转杆二与转杆一呈垂直放置，转杆二末端设置有卡柱二，卡柱二嵌入安装在另一侧凹槽二内，所述转杆一中部下端设置有下卡槽，转杆二中部上端设置有与下卡槽相匹配的上卡槽；通过设置转杆一和转杆二，转动转杆一和转杆二，使其呈十字架放置，可对井盖起到支撑的作用，可防止井盖向下坠落，提高检查井的安全性。
