Xi'an UEtx LG Outdoor Galvanized Monitoring Pole Wholesale

Description :

　　Monitoring poles, also known as monitoring poles, are divided into octagonal monitoring poles, circular tube monitoring poles, equal diameter monitoring poles, variable diameter monitoring poles, conical monitoring poles, with a height of generally 3-6 meters. They are mainly used for traffic roads, intersections, schools, government offices, residential areas, factories, border defense, airports and other places that require surveillance cameras. The use of monitoring poles has improved urban safety prevention and is an effective guarantee for residents' lives.

　　Specifications

　　

　　1. Typical urban road monitoring poles are made with a height of 6 meters and a horizontal arm of 1 meter, while residential monitoring poles are typically made with a height of 3-4 meters and an arm length of 0.8 meters.

　　foundation

　　

　　1. Unless there are special circumstances, all embedded parts of the monitoring poles are made of C25 concrete, and the steel bars provided comply with national standards and wind requirements. The cement used is 425 ordinary Portland cement. The proportion of concrete and the amount of small cement used should comply with the provisions of GBJ204-83; The threads above the flange of the embedded anchor bolts should be properly wrapped to prevent damage to the threads. According to the installation diagram of the embedded parts, correctly place the monitoring pole embedded parts to ensure the extension of the support arm.

　　2. The flatness of the concrete pouring surface of the monitoring pole foundation should be less than 5mm/m, and the embedded parts of the pole should be kept level as much as possible. The embedded flange should be lowered 20-30 mm below the surrounding ground, and then the reinforcing ribs should be covered with C25 fine aggregate concrete to prevent water accumulation.

　　lightning protection

　　1. The monitoring pole must have lightning rods and good grounding, so that the lead wires can be introduced into the ground (it is recommended not to conduct electricity through the pole body), and its grounding resistance should be less than 4 ohms; The direction is perpendicular to the driving lane (or as required by the engineer), and the anchor bolts are used as the main reinforcement;

　　install

　　1. Handhole wells must be installed near poles, control boxes, cable bends, cable conduits with a straight length exceeding 50 meters, or when the cable conduits at both ends are not in the same plane and are more than 100 mm apart.

　　2. The internal dimensions of the handhole well are required to be 500 (length) x 500 (width) x 600 (depth) mm, with gravel layers used for seepage; The walls of the handhole well must be coated with cement mortar.

　　3. The control box is equipped by the equipment manufacturer according to the required capacity, and the shell is made of cold-rolled steel plate with a wall thickness of not less than 1.2mm. The outer surface is sprayed with outdoor plastic powder and waterproof, anti-theft and heat dissipation measures are taken.

　　4. The depth of defects such as cracks, delamination, double skin, slag inclusion, or scratches that affect the material and mechanical properties of structural steel shall not exceed 1/2 of the negative tolerance of the steel thickness, and shall not exceed 0.5mm.

　　5. Design basis: Design wind load: 23m/s2, fatigue life: 30 years, constructed in accordance with the latest national standards such as "Carbon Structural Steel", "Code for Construction and Acceptance of Cable Lines in Electrical Equipment Installation Engineering", "Code for Construction and Acceptance of Steel Structure Engineering", "Code for Construction and Acceptance of Reinforced Concrete Engineering", etc.

　　Production requirements

　　1. Complies with current national standards and has a certificate of conformity. E43 type welding rods are used for carbon steel, and the quality of the welding rods should comply with the requirements of the latest national standard. Welding rods with peeling coating, rusted or damp core, and welding wires with rust should never be used. The welding dimensions meet the design requirements, and the welding waves on the surface of the weld metal are uniform, without cracks, slag inclusions, weld beads, burn through, non melting, arc pits, and needle like pores that affect the strength, and without defects such as wrinkles and interruptions. The depth of bite in the weld zone shall not exceed 0.5mm, and the cumulative total length shall not exceed 10% of the total length of the weld. The width of the weld seam is less than 20mm, the excess height of the weld corner is 1.5mm~2.5mm, the height of the weld corner of the fillet weld should be 6mm~8mm, and the size of the weld corner is not allowed to be smaller than the design size.

　　2. The anti-corrosion treatment adopts hot-dip galvanizing. Before the anti-corrosion treatment, the steel components should be effectively derusted. The hot-dip galvanizing thickness should not be less than 85um, and the zinc layer should be uniform. Copper sulfate solution should be used

　　During the etching test, there should be no exposed iron for more than 4 times, and the zinc layer should be firmly bonded to the metal body. After the hammering test, the zinc layer should not peel off or protrude. After zinc immersion, passivation treatment should be carried out, and a 48 hour salt spray test should be conducted

　　Verified as qualified. For every 100 meters of pole, the straightness error of the axis measurement shall not exceed 0.5 ‰, and the straightness error of the entire length of the pole shall not exceed 1 ‰.

　　embedded parts

　　1. The basic steel cage should be temporarily fixed, while ensuring that the foundation top plate of the steel cage is level, that is, using a level ruler to measure in two directions perpendicular to the foundation top plate, and observing its bubbles must be centered; The concrete pouring and compaction of the foundation of the embedded parts of the monitoring pole must be dense, and it is forbidden for the concrete to have hollowing;

　　2. During construction, plastic paper or other materials should be used to seal the pre embedded pipe mouth in advance to prevent concrete from leaking into the pre embedded pipe during pouring and compaction, causing blockage of the pre embedded pipe; After the foundation is poured and compacted, the foundation surface must be 5mm to 10mm higher than the ground level; Concrete must be cured for a period of time to ensure that it can reach a certain installation strength.

　　3. Each metal pole must be grounded with a grounding resistance of less than 4 ohms; The specific data of each pole foundation shall be subject to the on-site construction needs.

　　Intersection manhole

　　1. Road monitoring poles generally only require the use of small-sized manholes. For the convenience of equipment installation, manholes should be set near the monitoring pole; When the groundwater level is not high, only a gravel (sand) cushion layer is laid at the bottom of the manhole to prevent water from seeping into the ground during rainy days. However, there must be a concrete foundation cushion layer and cement mortar under the well wall; When the groundwater level is high, a 10cm concrete cushion layer should be added to the bottom of the manhole, and waterproof mortar should be applied to the well walls and bottom;

　　2. The net size is 500 × 500 × 600 (length × width × height), and it is built with Mu10 bricks and M5 cement mortar with a thickness of 240mm. The cover plate is made of C20 precast concrete with a thickness of 60mm and a double-sided configuration of Φ 8 @ 150. The elevation is the same as the pedestrian pavement or green belt, and the surface must be smooth with lifting holes. The cover plate is made according to the national standard. The specific data of civil engineering for each manhole shall be subject to the needs of on-site construction.
