control rod is used for outdoor monitoring camera device bracket of columnar road monitoring usually use cross arm 6 meters 1 meter to stop manufacturing. No special poling condition all monitoring embedded inserts for C25 concrete, concrete reinforced by agree with national standard and request by wind. The cement is 425 ordinary Portland cement. The ratio of concrete and minimum cement dosage should be agree with GBJ204 - The rules of 83. Must have good grounding best monitoring bar import lead public ( Don't go initiative conductive rod body) , the grounding resistance less than 4 o; Embedded parts above the anchor bolt flange thread wound good for damage. Device based on embedded parts figure properly positioned monitoring poling embedded parts, to ensure that the arm rod out direction (perpendicular to the driveway Or the request by the engineer) Anchor bolt as the main reinforcement. Control rod foundation concrete surface roughness is less than 5 mm/m stick upright degree of embedded parts. Embedded parts flange low out of the air around 20 ~ 30 mm, reoccupy C25 fine stone concrete cover, the reinforced ribs to avoid water accumulation. Bar, next to the control box, cable bend, cable pipe line length beyond 50 meters or both ends of the cable is not in the same plane are more than 100 mm apart, must set hand hole well. Hand hole hole inner size of the request for 500 ( Long) ×500( Wide) ×600( Deep) MM, with gravel layer for water penetration; Hand hole walls must be well cement mortar. Control box by the equipment manufacturer according to the required capacity of the equipment, the shell is made of high quality cold-rolled steel wall thickness not less than 1. 2 mm surface spray outdoor plastic powder and make waterproof anti-theft and heat dissipation. Structure and mechanical properties of steel shall not affect data crack, delamination, pitting defects such as double skin, slag or scratches depth shall not be greater than the thickness of the steel minus tolerance of 1/2, and should not be greater than zero. 5毫米。
