Yangzhou Global Solar will tell you about the installation instructions of monitoring poles solar street light-liters

Monitoring rods are also called monitoring vertical rods, including octagonal monitoring rods, cylindrical monitoring rods, variable diameter monitoring rods, equal diameter monitoring rods, and conical monitoring rods. Generally divided into 3-4 meters, 5-6 meters, 7-8 meters three monitoring poles. The production and production of monitoring poles should follow the local wind and temperature differences to design the corresponding monitoring pole styles and sizes. Installation of monitoring poles: 1. The concrete of the embedded parts of the monitoring poles is C25 concrete, and the steel bars are in line with the national standard and wind requirements. The cement is No. 425 ordinary Portland cement. The proportion of concrete and the minimum amount of cement should comply with GBJ204 -83; the reinforcement cage of the foundation should be temporarily fixed to ensure that the foundation cage is perpendicular to the horizontal plane, the concrete pouring of the embedded parts of the monitoring rod must be firm, and it is forbidden to have empty drums in the concrete. During construction, the pre-buried pipes should be sealed with plastic paper or other materials in advance to prevent the concrete from leaking into the pre-buried pipes when the concrete is poured and rammed, causing the pre-buried pipes to be blocked; after the foundation is poured, the foundation surface must be higher than the ground level. 5MM ~ 10MM; the concrete must be cured for a period of time to ensure that the concrete can reach a certain installation strength. 2. The monitoring pole must be well grounded. It is best to add lead wires into the ground (recommended to conduct electricity without taking the pole body), and its grounding resistance is less than 4 ohms; 3. The thread above the flange of the embedded part anchor bolt is well wrapped to prevent the thread from being damaged. According to the installation drawing of the embedded part, place the embedded part of the monitoring pole correctly to ensure that the extension direction of the support arm is perpendicular to the roadway. to shoot in the positive direction. 4. The flatness of the concrete pouring surface of the monitoring pole foundation is less than 5mm/m, and try to keep the embedded parts of the poles horizontal. The flanges of the embedded parts are 20-30 mm lower than the surrounding ground, and then use C25 fine stone concrete to strengthen the rib cover 5. Beside the pole, beside the control box, at the bend of the cable, when the straight length of the cable pipe exceeds 50 meters or when the cable pipes at both ends are not on the same plane and the distance between them is more than 100mm, hand hole wells must be set up. Hand hole wells The inner size of the reinforced cage is larger than that of the steel cage, and the gravel layer is used for water seepage; the four walls of the hand hole must be plastered with cement mortar. The thickness is not less than 1.2mm, and the exterior is sprayed with outdoor plastic powder and waterproof, anti-theft and heat dissipation. The size is generally 200X300, 300X400.7, the structural steel shall not affect the material and mechanical properties of cracks, delamination, heavy skin, slag inclusion and other defects The depth of points or scratches shall not be greater than 1/2 of the negative tolerance of steel thickness, and shall not be greater than 0.5mm.8. Design basis: design wind load: 23m/s, fatigue life: 30 years, according to the latest national standard version 'Carbon Plain Structural Steel, 'Code for Construction, Work and Acceptance of Electrical Installation Engineering Cable Lines9. The anchor bolts pass through the holes on the flange of the monitoring rod, and the nuts can be tightened.
