Can pipes pass through bridge openings?
Thread Content
There is a waterway that needs to be crossed; I don’t want to use an underground route, and there are no utility tunnels available. Is it possible to cross it by going through a bridge over the river?
Sure, but the approval process is rather complicated; it requires approval from both river management and road administration departments.
Supports can be installed along the river, passing through bridge openings; can pipe piers be built under those bridge openings? Are there any standards or regulations regarding this?
It’s not a standard; there are corresponding **regulations** for each! The area within 50 meters on either side of the river channel falls under the jurisdiction of the river management authorities, and any facility that could affect the river’s ability to discharge water must be approved by these authorities. Similarly, the impact of pipeline crossings under bridge decks on road safety also requires approval from the relevant road administration authorities
The construction method is simple, but the approval procedures are essential and quite troublesome. .
