1. The monitoring pole is used for the columnar support installed by the outdoor surveillance camera. Road monitoring usually uses a height of 6 meters and a crossarm of 1 meter. There is no special situation to monitor the condition of all monitoring pole embedded parts of concrete is C25 ç ¼, with the reinforcement in line with the national standard and the wind requirements. The cement is No. 425 ordinary portland cement. The proportion of concrete and the minimum amount of cement shall comply with the provisions of GBJ204-83;
2. The monitoring rod must have a good grounding. It is better to add the lead wire to the underground (it is recommended that the conductive rod does not go), and its grounding resistance is less than 4 Euro.
3, embedded parts anchor bolts above the flange plate is well wrapped to prevent damage to the thread. The monitoring rod is correctly placed on the monitoring pole embedded part according to the installation diagram of the embedded part to ensure that the extension direction of the boom arm is perpendicular to the traffic lane (or as required by the engineer) and the anchor bolt is used as the main reinforcement;
4. The monitoring of the base of the monitoring rod is less than 5mm/m to ensure that the level of the embedded part of the pole is as high as possible. The flange of the embedded part is 20~30 mm below the surrounding ground, and then the rib is covered with a C25 fine stone to prevent water accumulation;
5, hand-hole wells must be set when the length of the monitoring bar is longer than 50 meters beside the monitoring bar, next to the control box, cable bends, and when the length of the cable tube monitoring bar is longer than 50 meters, or when the cable tubes at both ends are not in the same plane above the 100 mm monitoring bar. Hand-hole wells require 500 (long) × 500 (width) × 600 (deep) MM. Gravel plies are used for water seepage; cement mortar must be wiped off the walls of hand-hole wells.
6. The control box is equipped by the equipment manufacturer according to the required capacity. The monitor rod shell adopts the high-quality cold-rolled steel sheet whose wall thickness is not less than 1.2mm to spray the outdoor plastic powder and make the waterproof monitor rod anti-theft and heat dissipation.
7. The degree of defects such as cracks, delaminations, heavy skins, slag inclusions, etc. of the structural steel monitoring poles shall not affect the material and mechanical properties. The depth of the pits or scratches shall not be greater than 1/2 of the negative tolerance of the steel thickness, and shall not be greater than 0.5 mm. .
