Monitoring pole is also called the monitoring poling, anise monitoring rod, cylinder monitoring pole, variable diameter monitoring, monitoring such as diameter rod, tapered monitoring pole. Generally divided into 3 - 4 m, 5 - 6 m, 7 - 8 m three monitoring pole. Monitoring of production should follow the local wind and temperature difference set

stem is also called the monitoring poling, including octagonal rod, cylinder rod, variable diameter monitoring pole, such as diameter rod and cone monitoring pole. Generally speaking, there are 3 - 4 m, 5 - And 7 to 6 meters 8 m monitoring pole. Monitoring of production should be according to the local wind and temperature difference design corresponding monitoring bar style and size. Monitor the installation of lever: 1. Monitoring for C25 concrete columns embedded inserts concrete, reinforcement in line with national standards and requirements of wind resistance. Cement is 425 # ordinary Portland cement. The proportion of concrete and the minimum amount of cement should meet GBJ204 - 83. Foundation reinforcing cage should be temporary fixed to ensure basic cage perpendicular to the horizontal plane. Monitoring pole foundation concrete pouring embedded parts must be strong. Don't allow concrete bucket. Port construction, the embedded pipe should be sealed with plastic or other materials in advance to prevent concrete mixture into the embedded pipe leakage, blockage caused by embedded pipe; Basis after casting, based on the surface of 5 ~ 10 mm must be above the ground. Concrete must be maintained for a period of time, in order to ensure the installation of the concrete can reach a certain intensity. 2. Monitoring must have a good grounding. The best and lead to the underground ( Do not recommend using conductive rod body) , the grounding resistance less than 4 ohm. 3. Embedded anchor bolts at the top of the threaded flange plate package, prevent damaged threads. According to the installation drawing of embedded parts, the right place monitoring pillar of embedded parts, to ensure that the support arm stretched out direction perpendicular to the driveway, the camera can be positive direction. 4. Monitoring the casting surface smoothness of concrete of the vertical rod for less than 5 mm/m, and try to keep the level of the vertical rod embedded parts. Embedded parts of the flange plate is lower than the ground around 20 ~ 30 mm, and then use C25 coverage of fine stone concrete reinforcement, prevent water. 5. Cable pipe line length of more than 50 m or both ends of the cable pipe is not in the same plane and space more than 100 mm, must be in a setting pole, control box, cable bend hand hole well. The inner periphery of the hand hole Wells is greater than the inner periphery of the steel reinforcement cage, gravel layer for water penetration. The walls of the hand hole Wells must with cement mortar. 6. Control box should by sheng da street lamps factory equipped according to the required capacity. The shell is made of high quality cold-rolled steel plate, wall thickness not less than 1. 2 mm, outside spraying plastic powder, and has the function of waterproof, anti-theft and heat dissipation. Size is usually 200 x300 and 300 x400. 7, materials and mechanical properties of structural steel shall not be affected crack, delaminating, defects such as double skin, slag inclusion, pitting or scratch depth may not be big steel thickness tolerance of 1/2, and shall not be greater than zero. 5 mm. 8. Design basis, design wind load: 23 m/s, the fatigue life: 30 years. According to the latest national standards 'carbon structural steel', 'the cable wiring and electrical installation engineering construction and acceptance norms', 'construction and acceptance of steel structure engineering, construction and acceptance of the reinforced concrete engineering and other related regulations, carry out the construction. 9. Anchor bolt through the control rods on the flange hole, nut can be tighten.
