The length of main tributary board is greater than the diameter of manhole, and first logical groove has been seted up to the first end of main tributary board, and the second end of main tributary board has been seted up the second and has been led to the groove. A locking part passes the first slot on the terminal surface of first logical groove and manhole for fix the first end of main tributary board on the terminal surface of manhole. The 2nd locking part passes the second slot on the terminal surface that the second leads to groove and manhole for fix the second end of main tributary board on the terminal surface of manhole. Therefore, the utility model provides a manhole locking device can be simple and convenient the container to having the manhole blockade, applicable in the manhole of different diameters and terminal surface thickness, operation labour saving and time
