what are the differences between stainless steel manholes and hand holes

What are the differences between stainless steel manholes and hand holes? Here we take a look! The main difference between stainless steel manholes and hand holes is just the size of the holes. The manholes are larger and the hand holes are smaller. Intuitively, the manhole is sealed with a strong circular manhole cover, while the handhole is sealed with a relatively weak load-bearing rectangular cover. In terms of volume, although there are many models of manholes, they generally have standard sizes and specifications, and are relatively large in size; hand holes have fewer models and are much smaller in size, and the size and depth are set according to the environment and requirements. Functionally speaking, the stainless steel manhole is the transfer point and relay point on the communication trunk pipeline, and the handhole is the terminal node on the communication pipeline network. In terms of location, stainless steel manholes can be built on main urban roads, sidewalks, etc., while handholes can only be built on sidewalks and green belts. Abstractly speaking, for stainless steel manholes, construction workers can be sent down to work in the holes, while for hand holes, construction workers should be able to squat or lie down on the well and construct directly with their hands. The functions of stainless steel manholes and hand holes: to inspect and repair the internal space of the equipment, and to install and disassemble the internal devices of the equipment. The above is about the difference between stainless steel manholes and hand holes.
