Portable tower series
Portable tower series
The installation of the tower structure shall comply with the relevant provisions of the “Code for Construction and Acceptance of Structural Engineering” GB50205-95. The tower shall be calibrated at any time during the installation process. After the verticality is completed, the actual deviation of the tower body shall not exceed 1/ of the measured height. 1500, the local bending shall not be greater than 1/750 of the measured length.
After the basic skeleton installation adjustment is passed, the exposed part is wrapped with C15 concrete.
After the tower is built, maintenance technical files should be established, and special personnel should be observed and maintained regularly. After the earthquake and the wind above the eighth grade, comprehensive observation and inspection of the tower axis, foundation and all nodes should be carried out and the loose bolts should be tightened.
If the tower tilt phenomenon is found, it should be promptly contacted with the relevant departments for proper handling.
The elementary base steel frame and the components buried in the concrete are all treated with hot-dip galvanizing and anti-corrosion treatment. The thickness of the hot-dip galvanized layer is generally not less than 80 μm. Due to the process requirements, the parts should be welded before the galvanizing. .
The foundation foundation construction shall be carried out in accordance with the relevant provisions of the following specifications: “Code for Construction and Acceptance of Foundation and Foundation Engineering” GBJ202-83 “Construction and Acceptance Specifications for Concrete Structure Engineering” GBJ50204-92
Test Project: Detecting the maintenance tower connection structure to avoid falling objects The normal operation of people and protection signal transmission facilities.
Uses: Full range of towers with a tower age of more than 1 year, adversity capacity, below 40 meters below wind level below 6/40 meters above wind level 5;
auxiliary facilities: no scaffolding support. Will not interrupt the normal operation of the signal transmitter.
Construction Cycle: arrive at the site survey within 1-5 days. The tower of 50 meters and below will be completed in 5 working days, and each working day will increase by 1 working day (if there is special process requirement, the construction period will be extended). The relative distance of relocation is within 15 km. 60 m or less by weight of 30 t 15 days or less completed, each of the high
increase of 10 m (or weight increase of 2 tons), increasing from 5 km time increases two days (in case of force majeure, extension of time)
service : Unconditional repair of the original quality problem within 10 years after the replacement of the metal component.
