What are the design codes for power towers? What are the requirements for power tower installation?

Provide the load of the ground wire on the tower (according to the domestic standard in China, and the American standard in foreign countries) 2 According to the meteorological conditions and the overhang string draw the gap circle of the tower (that is, to determine the minimum size of the tower head, the smaller the more economical).

3. Draw a one-line diagram of the tower according to the gap circle.

4. Use software (domestic is Daoheng, large design institutes have their own secret software, foreign engineering with tower) to input the tower model into the software, plus the load, the rest is the software itself (this is also the most rare part, because there are often errors, the calculation is not convergent, you need to find the error again and again).

5 If the software is good, the tower will be designed (believe in the software, believe in the science, if you don't believe it, then move on).

The design code of power tower includes electrical design code for civil buildings, design code for low-voltage power distribution, design standard for building lighting, etc., if you need to design power tower, it is recommended to consult Eternal Communication.

1. Pole erection: After the pole arrives at the site, the Chinese pole tower network uses a 12-ton crane to erect the pole, manually righting and backfilling, and before the pole is erected, it is necessary to install a cross arm and assemble the pole.

2. Assembly of the newly built pole switch table: After the pole is assembled and erected, four people assemble the switch table fittings, leads and switch installation, and the installation standard implements the design drawings.

3. Erection of pole wires: For the renovation project, the old wire with the new line is used for the line of defense, and the car is used for traction, and the communication must be kept smooth during the traction process to prevent the occurrence of faults such as stuck lines and broken lines.

4. Pipe jacking through the road: Before construction, it is necessary to dig 4 meters * 3 meters * 4 meters of operation pits on both sides of the road to facilitate pipe jacking construction. [Click to get preferential policies].

If you want to know more about the design specifications of power towers, we recommend choosing Eternal Communication. In order to ensure the accuracy of the technical drawings for processing input, Eternal Communications will first check the technical conditions and processing requirements provided by the user in order to ensure the accuracy of the technical drawings entered by the processing. The microcomputer is connected to the terminal of CNC equipment such as cutting and bending to ensure the reliability and accuracy of the processed products.

Establish a firm and sober quality concept, pay attention to every detail in the product quality chain, strictly require all products to meet the standards, and strive to reduce defects and deficiencies to zero.

DL T 5154-2002 Technical Regulations for the Design of Overhead Transmission Line Tower Structures; Design code for steel pipe poles for overhead power transmission lines; Many, many, many, and if you open a specification, you can see a lot of other reference specifications in it.

1.Positioning and measuring pay-off: positioning and marking. According to the design requirements and geological exploration data, sometimes the position of the tower foundation that needs to be changed is measured and confirmed by the representative of the construction unit. Once the measurement reference position has been determined, it should be verified against the design to ensure its accuracy.

2.Earthwork excavation: excavation according to the design requirements to ensure the length, width and depth of the foundation pit and the beam pit.

3.Cushion concrete pouring: After the foundation pit and tie beam are dug well, the foundation cushion concrete (generally about 250px) is poured according to the design requirements, and after the concrete is hardened, the reinforcement skeleton in the foundation and tie beam is tied.

4.Tower base formwork installation:

Before pouring the foundation and connecting beams, the template should be set up, and the size should meet the requirements. The formwork and its support should be designed according to the engineering structure, load, foundation soil type, construction equipment and materials. The formwork and its support should have sufficient bearing capacity, stiffness and stability.

It can reliably withstand the weight, side pressure and construction load of the poured concrete. Before pouring concrete, the formwork project should be accepted. During the pouring process, observe and maintain the formwork and its support, and deal with abnormal situations in time.
