pipe cost and application consideration, underground water supply pipe network transformation, general is conducted during the period of road construction reform.
For old pipeline failure prevention, funnelled through the analysis of leak detection.
But for tap water pipes buried in the ground, more information can be collected.
At the same time, because the water pipe belongs to the ancillary facilities of roads, in general, only detected funnelled to passively excavation work processing.
For old pipes, such as the special cases, is often difficult to take the initiative to excavate repair or replacement.
This kind of work is more on the road during the reform.
Learned, when laying underground water pipe, for ductile iron
pipe distance pipeline under the top 20 cm area, requirements of backfill soil is relatively soft, not with big rocks and debris, and must take backfilled, shall not adopt any machine operation.
Ductile iron pipes project before start working in construction, the construction unit and find out the underground construction and installation construction enterprises shall be submitted to the department of water supply water supply network and ancillary facilities.
