The dimensions and technical requirements of the Tower
First, the generation of the work of the content: Party B is responsible for the daily cycle patrol maintenance, fault handling and repair, emergency treatment, engineering acceptance and so on of the base station tower and bracket in the generation dimension area.
1, party B is responsible for the completion of the new base station, relocation base station, expansion of the base station project acceptance of the tower, engineering exploration, engineering work.
2, Party B is responsible for the completion of other related maintenance and various special work.
II. Daily Maintenance requirements
The following day-to-day maintenance requirements for party B must be carried out on behalf of the work content. 1, party B is responsible for the day-to-day maintenance work, in accordance with the requirements of the party a quarterly basis for the base station towers and other equipment to carry out a patrol maintenance, complete inspection four times a year. The main contents of the site inspection and maintenance of the base station tower include: The inspection and anti-corrosion treatment of the basic inspection, verticality detection, bolt filling and fastening, component inspection, antirust treatment, lightning protection grounding inspection, metal components above the tower base (including bolts, suspended anchor, etc.).
And the day feeder system security risks timely feedback report.
2. In special weather, before and after the disaster should be carried out emergency patrol, every six degrees or above the earthquake or eight above the gale or heavy ice weather, the tower should be the axis, foundation and all the nodes for comprehensive observation and maintenance, when the thickness of the tower icing more than 30mm, should take appropriate measures to remove the ice.
3, Party B is responsible for the work of the project and the inspection cycle, the development of maintenance and repair plan, monthly 25th to provide to party a audit after implementation. 4, Party B is responsible for the first month of the month maintenance operations completed in time to report to party a.
Mainly listed last month in the patrol generation and maintenance of the management process found in the base station problems, tracking and resolution, the content should include: Time, site number, site name, existing problems, to solve the situation.
5, party B to ensure that the daily inspection of the test record data is true and effective, and timely to party a generation of production management Department report.
6, Party B is responsible for its maintenance within the base station (including removable base station) site, station number, accurate latitude and longitude, tower height and type, number of platforms, as well as panoramic digital photos and other data compiled, and timely report to party A at the end of each month, and ensure that the data and actual equipment accurate. 7. Party B shall complete the verification and registration of fixed assets according to the requirements of party A.
(check with equipment maintenance cycle)
8, for the base station tower and other outdoor facilities, party B should ensure that “no climbing” warning signs intact, installation requirements in line with the relevant national regulations.
9, Basic testing:
①. Carries on the level measurement of the tower foot, the detection foundation relative subsidence degree, and compares the historical record data, carries on the evaluation to the tower usability, the formulation rectification measure, examines the Tower foundation grounding is good.
②. Check whether the anchor bolts of Tower foot, the specifications of the nuts are in conformity with the defects, replace the defective, fill in the defect, check the effectiveness of the anti-theft measures for the anchor bolts of the tower foot, and rectify the anti-theft problem.
③. To the tower, it is also necessary to check the stress condition of the building structure, and whether the structural member with the stress point is cracked and the deformation is too large.
⒑, verticality Detection:
Measure the verticality of the tower to meet the standard requirements, and compare with the historical data, if there is discrepancy, analyze the reason and make corrective action.
⒒ and bolts filling and fastening:
Check the whole tower bolts have defect, rust, loose, fill all missing bolts, replace rust damaged bolts, the whole tower screws fully fastened.
⒓, Component inspection:
①. Check the tower body members, whether the weld seam is cracked, galvanized or coating is damaged, there is no obvious deformation of the components, found that the defective components to replace, the local rusty components for rust paint.
②. The key parts of tower connection, mast, lightning rod and so on are focused on maintenance and fastening, and the existing problems are dealt with in time.
③. To the pull line tower, check the tension of the cable, pull the fixed ring, the gold fixture is fixed and reliable, there is no defect, the existence of problems in a timely manner.
⒔, Anti-rust treatment:
According to the rust of the tower members, the rust-removing paint must be done.
⒕, lightning protection grounding inspection: Measuring grounding resistance, check whether the lightning-proof grounding flat iron is rusty, the connection is firm, rust the flat iron rust paint or replacement treatment, the connection is not firmly welded or fastened.
