12 meters cement pole pole and cable anchor pit buried depth requirements:

7m rod buried depth of ordinary soil 1.3m, hard soil 1.2m, paddy field, wetland 1.4m, stone 1.0m;

8m pole buried depth of ordinary soil 1.5m, hard soil 1.4m, paddy field, wetland 1.6m, stone 1.2m;

10m rod buried depth of ordinary soil 1.7m, hard soil 1.6m, stone 1.6m;

12m bar ordinary soil depth 2.1m, hard soil 2.0m, stone 2.0m;

The buried depth of 15 m bar is 2.3m for ordinary soil, 2.2m for hard soil and 2.2m for stone.

The buried depth of 18 m bar is 2.6m in ordinary soil, 2.4m in hard soil and 2.4m in stone.

The buried depth of the ground anchor pit is 1.4m for ordinary soil, 1.3m for hard soil, 1.5m for paddy field and wetland, and 1.1m for stone. The depth of the pole shall be carried out in strict accordance with the regulations: the depth of the pole for the construction of the pole is not enough and the area of loose soil shall be equipped with chuck; In the soft soil, the bottom plate should be added to the bottom of the denier fishing rod, terminal rod, distribution rod, crossing rod and long rod stop rod. The above electric pole in the stone soil and stone zone can not install chuck, chassis, on the side of the road where it is easy to be hit by vehicles, should be added to protect the pole pile, increase the height of 40-50cm.

12 m cement pole weight specification configuration weight

1, for ordinary (non-prestressed) conical reinforced concrete 12 meters pole, if the reinforcement is 14/φ14, tip diameter 190mm, root diameter 350mm, the pole mass 1100kg. 2, prestressed conical reinforced concrete 12 meters pole, if the reinforcement is 16/φ4.8, tip diameter 190mm, root diameter 350mm, pole mass 1000kg.

Me: Ordinary (non-prestressed) conical reinforced concrete 12 meters pole, if the reinforcement is 14/φ14, tip diameter 190mm, root diameter 350mm, the pole mass 1100kg. If the reinforcement is 16/φ14, tip diameter 190mm, root diameter 350mm, the pole mass 1130kg.

2, prestressed conical reinforced concrete 12 meters pole, if the reinforcement is 16/φ4.8, tip diameter 190mm, root diameter 350mm, pole mass 1000kg. If the reinforcement is 20/φ4.8, tip diameter 190mm, root diameter 350mm, the pole mass 1020kg.

3, cement pole classification:

Ordinary cement pole referred to as "Pu pole", prestressed pole, high strength cement pole, flange splicing pole, cement pole

Telegraph pole is a kind of hypothetical wire pole, is electric power, communication, urban rural network high and low voltage power transformation of all kinds of electric overhead lines and communication cable erection, is one of the important infrastructure of power supply, communication, generally used for the state grid, electric power company, power supply, mobile company, Unicom company, energy, heavy industry and other group company line erection.

Cement pole raw materials:

Steel, concrete, cement as the main raw materials, auxiliary materials are: stone, sand water, so also called reinforced concrete pole.

Cement pole height classification:

Generally according to the height of 7 meters of poles, 8 meters of poles, 10 meters of poles, 12 meters of poles, 15 meters of poles, 18 meters of poles, 1 meters of poles. The national standard is 15 meters in length. But because the project needs 18 meters and 21 meters of poles for flanges to join the poles, for example, some power projects need to use 7 meters of cement poles. Then the general is custom cement pole, that is, from 8 meters of pole cut out.

Production technology and process of cement pole:

1. Steel bar processing and steel cage production: steel cold drawing, cutting, bending and binding
2. Concrete batching and mixing system: concrete batching and mixing
3. Pole molding: centrifugal hair molding round pole (need centrifuge, mold and cloth machine and other equipment), or vibration molding other types of pole (need cloth machine, shaking table, mold and other equipment)
4. Steam curing: the newly formed pole belt touch and stop for a period of time, enter the steam curing room, curing the cement pole for a few hours
5. Demoulding and maintenance: the pole with the mold out of the maintenance room, demoulding, cleaning, demoulding poles continue to moisturize or soak water maintenance for a period of time
Mold investment is large, production efficiency is determined by mold turnover.
The production of cement poles is made by steam curing in a steel mold at a certain speed (generating enough centrifugal force to make the cement material form a hollow pole). The steel die is composed of two half dies for feeding and taking out the finished product. Therefore, before forming, it is necessary to make steel bar skeleton (steel cage) and conform to the proportion of cement slurry (cement + stone + sand + water) mixing, so the production principle is simple, but it needs certain lifting equipment, site and certain mechanical equipment.

The difference between cement pole factory and company:
Pole factory is the individual nature of the self-employed, limited company is an enterprise legal person, there are strict quality inspection procedures, because of the different equipment and production technology, so pole manufacturers produced cement pole from the length, pressure resistance, corrosion resistance coefficient have different enterprise quality, enterprises have strict control procedures, different lengths of poles need different lengths of pole grinding tools. In quality because of the selection of raw materials such as steel bar thickness, cement quality and so on, the quality of the poles produced is also very different. Mobile phone :+8613639411999
