Abstract
PURPOSE: To prevent the inflow of large amounts of rain water and soil and sand into the cover of a manhole by a method in which a float chamber into which rain water can flow is provided below the cover of a monhole, a float valve is housed in the chamber, a closable rain water-inducting port is provided in the chamber, and a filter is provided to the rain water-inducting port of the float chamber.
CONSTITUTION: A float chamber 4 is provided below the through hole 2 of the cover 1 of a manhole, etc., and a float valve 3 is housed in the chamber 4. In case where there is no inflow of rain water, the float valve 3 is suck in such a way as to form a space between the upside of the float valve 3 and the wall 8 of inflow path and also an air pathway by a rain water-inducting port 9 and a through hole 2. On the other hand, in case where rain water comes in through the through hole 2 and the inducting port 9, the rain water is introduced in the float chamber 4 through a filter 13 as shown by arrows and then discharged through a drain port 5. When the inflow of rain water is larger than the amount of drain water from the drain port 5, the level of water inside the chamber 4 rises, the float valve 3 floats up, the valve 6 closes the drain port 5, and the float valve 3 closes the inducting port 9.
