4.1.4 Cabling pipe tubing materials, shall meet the following requirements:
(1), such as communication channels in building the city, generally using concrete pipes, and are advised to six holes (diameter 90mm) pipe block for the base combination, or a 62mm diameter tube and other small pieces; the water table is high, Vision plastic pipe;
(2) Cabling separate pipeline construction, should use double-wall corrugated pipe, composite foam tube, solid wall pipe and other plastic pipe combination, the pipe diameter shall meet the specifications for the provisions of Article 4.1.5;
(3) under the following conditions should be steel pipe:
pipeline attached to or hung on a bridge across the ditch, there are suspended span;
requires the use of pipe jacking method when crossing the road or railway bed;
depth too shallow or too heavy road load;
special soft ground or may be subject to strong vibration;
has a strong impact on electricity or interfere with necessary protection;
building cabling on the introduction of lead pipe or tube;
lot more serious in the corrosion of steel pipe, steel pipe to make the anti-corrosion treatment.
