Sub: first reserved and embedded, then pipeline installation; First underground pipe, then above ground pipe; Main pipe first, then branch pipe; Cooperate with civil engineering to do a good job of reservation and embedding, and then cross and cooperate reasonably after the completion of appropriate civil engineering procedures; For the construction of some outdoor pipelines, the construction time should be reasonably selected. Generally, the indoor workload has been mostly completed, and before the construction of outdoor pipelines, the principle of "first down then up, first large then small" should be followed.<BR>
