Zhengzhou garage greening drainage board company

When setting up a water collection well, the concrete thickness of the underground garage floor should be used as much as possible to arrange underground drainage pipes. For example, the thickness of the floor of an underground garage is usually ~100mA. After excluding the distance between the upper and lower steel bars and the protective layer, there is still ~100mA space for the underground drainage pipe to pass through. This height should be used during design to minimize the slope of the buried drainage pipe as much as possible. The minimum design slope of the buried drainage pipe uses the principle of water flowing to lower places to extend the length of the buried drainage pipe and expand the concentration. The catchment area of the well. When setting up water collection wells, special attention should be paid to the following points. There should be no settlement joints, expansion joints, deformation joints in the water receiving area of each water collection well. According to the "Building Water Supply and Drainage Design Code", drainage pipes in buildings must not pass through the above seams. . Each fire protection zone must have an independent water collection well to prevent directly buried drainage pipes from crossing the fire protection zone. In the event of a fire, although the fire-proof roller shutters will isolate the two fire-proof zones, the hidden danger is buried under the garage floor. In a manned underground garage, an independent water collection well should be set up in each civil air defense unit. Directly buried drainage pipes should not pass through the protection unit, and direct buried drainage pipes cannot pass through civil air defense areas and non-human air defense areas.
