Problems solved by technology

[0005] 1. There are a lot of missing original materials;
[0006] 2. On-site routine inspection is easy to implement for the upper structure, but it is actually difficult to operate the inspection of the foundation, so it is often not evaluated, and the overall safety of the pole station mostly depends on the safety of the foundation;
[0007] 3. The basis for the calculation review is not uniform, and the calculation parameters selected by the engineer are highly random, which affects the reliability of the final evaluation result

Embodiment 1

[0029] Step 1, routine testing (without original data)

[0030] Communication poles and towers are mostly located on both sides of the road, with a height ranging from 5m to 25m. On-site measurement includes measuring pole height, hardness, bottom diameter, top diameter, wall thickness, etc., to obtain basic data such as pole station height, section conditions, material, diameter, and wall thickness of each section.

[0031] Routine inspection of a batch of similar towers includes using instruments to measure the material, wall thickness, and geometric dimensions of poles and towers, recording the number of existing antennas and installation heights, and collecting raw data required for finite element modeling; common equipment includes ultrasonic thickness measurement instrument, Leeb hardness tester, hand-held laser range finder, steel tape, etc.

[0032] In the embodiment, 50 are selected for routine testing. Routine inspection includes using instruments to measure the ma...

Embodiment 2

[0084] Other test methods and steps in this embodiment are the same as those in Embodiment 1, except that in this embodiment, the vehicle-mounted mobile method is used for static force detection and dynamic detection.

[0085] Such as image 3 , Figure 4 , Figure 5 , Image 6 As shown, the mobile integrated detection device is used to test the communication antenna (tower) G, and the test includes static force detection and dynamic detection.

[0086] The mobile integrated detection device includes a mobile unit, a static detection unit and a dynamic detection unit.

[0087] The mobile unit includes a mobile platform 11 , a ballast box 12 , a reaction frame 13 , two supports 14 , and a blocking member 15 .

[0088] The mobile platform 11 is a wheeled vehicle or a crawler vehicle. In the embodiment, the mobile platform 11 is a wheeled truck, and the blocking member 15 is used to fix the wheels of the truck so that the truck cannot move.

[0089] The ballast box 12 is ar...

Abstract

The invention provides a method for comprehensively evaluating stock rods and towers for additionally installing communication antennas. The method comprises the following steps: 1, carrying out conventional detection on a batch of multiple rods and towers of the same type to obtain multiple pieces of original data; 2, inputting the related data into a finite element calculation model for analog calculation, and respectively obtaining a loading tension control value required by a static test and a first-order natural vibration frequency theoretical value of a rod; 3, selecting a preset number of rods and towers as samples of standard rods and towers; 4, performing static test on the sample to obtain a test top displacement value and a test foundation top displacement value, and comparing the test top displacement value and the test foundation top displacement value with design specifications; 5, performing dynamic test on the sample to establish a dynamic characteristic parameter sample library; 6, determining a lower limit value of a standard library mean value; 7, carrying out power test on the rest rods to obtain a test natural vibration frequency value of each rod; and 8, testing the rods and towers of which the natural vibration frequency values are greater than the mean lower limit value, and newly adding antennas.

Description

technical field [0001] The invention belongs to the field of infrastructure construction, and in particular relates to a method for comprehensively evaluating stock poles and towers used for adding communication antennas. Background technique [0002] With the development of 5G, the number of communication antennas that need to be installed far exceeds the number of 4G communication antennas. There is a great demand for installing communication antennas on original communication pole stations or other social pole stations (such as municipal pole stations, electric power pole stations, etc.). After the original pole station is installed with communication antennas, whether the safety of the structure itself can be guaranteed is the main problem that needs to be solved at present. [0003] The current traditional evaluation method needs to obtain the basic data of the tower (such as height, diameter, wall thickness, material, etc.) from the original data or on-site routine in...
