Description

Technical Field

[0001] The utility model belongs to the technical field of drainage engineering, and particularly relates to an assembled rainwater well structure and a casting mold thereof. Background Art

[0002] Rainwater wells are used to dredge rainwater on ground roads. On the walls of prefabricated rainwater wells, holes for rainwater collection pipes need to be reserved. Later, the rainwater collection pipes are inserted into the holes on the walls of the rainwater wells for connection, and are compacted with dry hard mortar. The size of the reserved holes on the rainwater wells should be slightly larger than the diameter of the rainwater collection pipes to facilitate the installation and connection of the rainwater collection pipes. However, if the size of the reserved holes on the prefabricated rainwater wells is larger than the outer diameter of the pipes, it is easy to leak or cause roadbed hollowing, road surface settlement and other diseases. If the size of the reserved holes is too small, the rainwater wells and rainwater collection pipes will not be connected. It is difficult to operate during the construction and the construction efficiency is extremely low. Therefore, when installing the rainwater collection pipe, the construction workers need to repeatedly adjust the size of the holes reserved for the rainwater collection pipe, which affects the construction efficiency, and dry hard mortar is needed to fill the gap between the reserved holes on the rainwater well and the rainwater collection pipe. When flushed by rainwater or affected by the temperature in winter and summer, the filling dry hard mortar is easy to fall off and requires frequent maintenance. It is also easy to leak and cause the roadbed to be hollowed out, causing the road surface to sink, increasing maintenance costs, and posing a major hidden danger. Utility Model Content
