Abstract:
A manhole includes a device for safely closing and locking the manhole, which has a cylinder with centering pins that is attached to a slab and is rotatable with an operating key acting on the pins, and further includes an anti-burglary block, which in locked position is positioned inside the cylinder and hides and protects an anti-theft bolt positioned inside a hole, which crosses the entire anti-burglary block and has a larger diameter at the front and the same diameter as the anti-theft bolt in the back, so as to receive the anti-theft bolt in a threaded spot in the inner wall of the cylinder and enable placement of the anti-theft bolt in the body of the anti-burglary block when totally tightened into the threaded spot, wherein the end of the anti-theft bolt, in closed position, is housed in a locking hole on a circular support of the cover.
