Manufacturing to street lamp monitoring pole foundation courtyard

Monitoring rod at 1, no special circumstances all monitoring poling embedded inserts for C25 concrete, concrete reinforced by agree with national standard and the wind requirements. Meanwhile the cement for general Portland cement, 425. The ratio of concrete and minimum cement dosage should be agree with GBJ204 - 83

1, no special circumstances all  monitoring pole foundation monitoring poling 【 Monitoring poling also called monitoring pole, divided into anise monitoring pole, circular tube monitoring, monitoring such as diameter rod, variable diameter monitoring pole, conical monitoring pole, highly general for 3 - 6 meters, mainly for road transportation, intersection, schools, government, community, factories, frontier defense, airports where the surveillance camera. 】 Embedded parts' Embedded parts ( Precast and built-in) It is pre-installed ( Buried) Artifacts within the concealed work. Is casting is placed in the structure of components, the lap of the upper masonry structure based on. 】 To C25 concrete, concrete reinforced with gb and the wind requirements. Meanwhile the cement for general Portland cement, 425. The ratio of concrete and minimum cement dosage should be agree with GBJ204 - The rules of 83; Embedded parts anchor bolt 【 Mechanical components are installed on the concrete foundation, the bolt of the J shape, one end of the l-shaped embedded in concrete are used. 】 Above the flange thread bandaging outstanding for damage. According to the embedded parts installation drawing correctly placed to monitor poling embedded inserts, guarantee the arm stretched out. 2, monitoring of poling foundation concrete surface roughness is less than 5 mm/m try to keep the vertical bar embedded parts level. Embedded parts below ground around 20 ~ 30 mm flange plate, reoccupy C25 fine stone concrete cover, the strengthening rib in order to avoid water accumulation. 1, monitoring is necessary to have a lightning protection lightning rod and earthing outstanding and best lead into the underground, Don't go advocated conducting rod body) , the grounding resistance less than 4 o; Direction and driveway straight ( Or in accordance with the requirements of engineers) Anchor bolt as the main reinforcement; Unit 1, beside the lever and control box, 【 The control box is used widely. 】 Beside, cable bend, cable pipe' Cement cable pipe also known as power line cable, power cable pipe, cement pipe, cement cable, power cable pipe cement, etc. 】 Straight line length beyond 50 meters or both ends of the cable pipe is not in the same plane are more than 100 mm apart, it is necessary to set the hand hole Wells [ Hand hole Wells is refers to the buildings or for the convenience of laying cable in municipal engineering, build the can't go to people, can only be reached in the well and convenient threading, general is given priority to with cement block structure. 】 。 2, hand hole hole inner scale for 500 ( Long) ×500( Wide) ×600( Deep) MM, with gravel layer for water penetration; Hand hole hole walls is necessary to put the cement mortar. 3, control box by the equipment manufacturer according to the required capacity of equipment, shell selects the 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. 4, the structure and mechanical properties of steel shall not affect data crack, delamination, double skin, slag inclusion and other defects pitting or scratch the depth of the negative half of the public servants shall not be greater than the thickness of the steel, and should not be greater than zero. 5mm。 5, planning basis: planning wind load: 23 m/s2, fatigue life: 30 years, according to the latest standards of the state version 'carbon structural steel' Carbon Structural Steel, English name: Carbon Structural Steel, Carbon Steel one. 】
