Steel rod inside the water quite common steel rod inside the water What are the dangers? Steel rod inside the water directly caused steel rod bolt especially between the bottom and top of the foundation bolt flange and pipe wall corrosion, threat the safe operation of steel rod, need to be addressed properly. Hydrocephalus may cause electrical steel rod reason to :( 1) The majority of the top side of galvanized steel rod consider setting aside zinc vent hole, steel rods in the rod cover existing design generally not fully cover vent holes zinc, rain possible along the vent hole into the steel rod inside zinc. (2) Since the steel bar processing, and wire tension line construction factors influence Flange gaps may exist, rainwater infiltration from the flange connection. Relatively speaking, in particular, are more likely to exist voids large rotation angle steel pole Flange steel rod. Steel rod to determine the conditions of use: 1 wire, grounding wire model and determine the maximum use of stress according to the preliminary design review approval documents, leads this project selected for LGJX-240/30 ACSR (GB1179-83 technical standards ), design safety factor of k = 5, Maximum stress 52.06N / mm2, lightning-line a selection of 5% aluminum-zinc alloy coating strand rare earth GJX-50, the safety factor k = 8, Maximum stress 147N / mm2, other a selection of composite fiber OPGW lightning line. 2 Use span steel rod to determine Shengda Power Co. project to take into account the city line, the terrain is flat, so that the different levels of the tower site span and vertical span dispersion is not, so the design span steel rod used to determine as follows: horizontal span of 180m, vertical span of 200m, on behalf of the span of 200m. Advantages of steel rod: (1) high intensity, to provide a strong guarantee safe operation; (2) high tower can be designed to meet the needs across the sidewalk, trees requirements; (3) easy to implement multi-loop, thus greatly reducing the city congestion corridor; (4) do not play cable, small footprint, reduce occupation of urban corridor; (5) can achieve full galvanized steel tower, steel pole using small footprint, attractive appearance, compared to the surrounding environment
