Some data that must be known for dry communication line engineering

One line engineering material

Fiber optic cable

Measurement length + connector remaining (approx. 8-10 meters on one side) + 7/1000 loss

If it is relying on an optical fiber cable from the bureau, it needs to add the incoming optical cable (50-100 meters).

2. Connector box

Generally 2 km of a fiber optic cable, after the distribution on the drawings, you can get the number of joints. Normally 100 joints allow loss of 1 joint box

3. Strand

7/2.2 Steel strands are generally used for hanging wires, side pulls for both sides and side pulls, and a small amount for auxiliary devices for angle bars, auxiliary devices for elevation/depression angles

7/2.2 Strand = Strand 221.27 kg per kilometer x Number of catenaries + 3.02 kilograms per strand × number of draw lines + 2 kg per auxiliary unit × number of auxiliary units

7/2.6 steel wire is generally used for cable and auxiliary hanging wire

7/2.6 Strand = strand 4.41 kg per strand × number of strands + 322.27 kg per kilometer × (auxiliary strand length + high stub length)

7/3.0 Strand is generally used for cable (corresponding to the case where the hanging line is 7/2.6). For example, the cable for the auxiliary hanging line

7/3.0 Strand=Pull Each 5.88kg×Pull Lines

4. Galvanized iron wire

4.0 Iron wire is generally used to suspend wires, lead steel pipes, lightning rods, and angle bar auxiliary devices that are made at a depth of 5-10 meters, as well as reinforcement devices such as wooden fences and wooden piles. Wooden poles, crossbars, rarely used.

1.5 Iron wire is generally used for tying and tying of the wire and hanging wire, auxiliary hanging, auxiliary device for suspending wire, auxiliary device for assisting and declining yaw angle, and arranging the tail of overhead wire and installing the auxiliary cable for overhead cable.

1.5 wire = production drawing line usage + erection hanging line usage + erection auxiliary hanging 0.03 kg every 100 meters + hanging line auxiliary device, elevation and depression angle auxiliary device 0.02 kilograms each plus + helper cable after-line usage + lead on the optical cable and indoor channel cable

5. Electric pole

Counted on the drawing, there are 3 normal loss of 1000 roots

6. Hoop

Pulling wire hoop D164, generally used for pulling wire and hanging wire terminal number

Single hanging wire hoop D164, generally used to make the number of hanging wire from the map

Double hanging wire holding hoop D164, generally used for a pole road, at the same time newly installed two hanging lines, the number of counts from the map

7. Wear nails

Zinc-plated nails 16×60: generally used for hanging wire hoop, 3 hoops per single hanging wire, 4 hoops per double hanging wire

= 3 x single hanging wire hoop number + 4 x double hanging wire hoop number

Zinc plated nails

18×60: generally used to pull wire hoop, each wire hoop 2 only

= 2 x number of hoop hoop

8. Three eye splints

Three single-slot splints: generally used for hanging wire hoop, each single hanging wire hoop 1 pay, each double hanging wire hoop 2 pay

Three-eye double-groove plywood is generally used for pulling wire (plywood method) and the end of hanging wire (plywood method)

One cable corresponds to 2 pay 3 eyes double slot splint (7/2.6 and below)

One pull line corresponds to 4 pay 3 eyes double slot splint (7/3.0)

9. Back ring

Liner ring is generally used to pull wire, hanging wire termination, hanging wire connection, auxiliary devices, etc.

Five-flint rings correspond to 7/2.2, 7/2.6 strands

Seven-flint rings correspond to 7/3.0 strands

Lining ring = number of pulling lines + number of wire hoop + number of assisting devices for elevation and depression angle + 2x number of auxiliary units for angle bar + 2 x number of connections for hanging wire

10. Galvanized steel card

It is generally used for cable pull (clamp method), end of hanging wire (clutch method) and corner bar auxiliary device

7/2.2, 7/2.6 steel wire corresponding to No. 8 steel card, 7/3.0 steel wire corresponding to No. 10 steel card

A pull line 6 steel cards, angle bar auxiliary device requires 4 steel cards 8, 4 10 steel cards.

11. Hook (35mm) 2060 / per km × laying optical cable kilometers

12. Steel anchor

The same number of cables as the number of cables, the loss of 1000 loss 3

16×2100, 12×1800

13. Cement block (cement disc)

Same number of anchors as steel handles

14. Sub-tube

In the overhead cable project, it is mainly used to protect the optical cable and lead the optical cable.

Plastic tube

The overhead cable installation requires 25 meters per kilometer. The indoor channel cable requires 103 meters for every 100 meters, and when looking at the cable, how far the manual hole is from the pole, which is generally very close.

15. Fiber optic cable rest frame

For overhead cable joints, one connector 2 for fiber optic cable rest

16. Power line protection board

Used to cross the hanging line and the power line, the two sides exceed the power line by about 1 meter, according to the actual statistics

17. Some cement products, such as cement discs, chucks, etc., are mainly used where the soil is relatively soft.

18. Cement, mainly used for stone protection piers,

19. Explosives, explosives, and fuses are mainly used for poles and pull-line cases

Second pipeline engineering materials

The main materials include: optical cable, splice box, plastic tube, three-hole plug (put three tube), plastic plug, plastic tray or plastic hook

1. The actual length of the cable + connector remaining (about 8-10 meters on one side) + 15ths of a thousandth of loss + the remaining line of each person, hand hole (about 1-2 meters)

If it is relying on an optical fiber cable from the bureau, it needs to add the incoming optical cable (50-100 meters).

4. Plastic sub-tubes; 28/32mm plastic sub-tubes; now basically 3 or 4 sub-tubes are placed in each tube hole, and the corresponding sub-tube material is 3030 meters and 4040 meters.

5. 3 hole plugs (lay 3 children)

It is used for plugging the pipe hole to prevent foreign matter from entering the pipe hole. Each person has two holes in the hand hole.

6. Plastic stopper

It is used to block the inner pipe of the pipeline to prevent foreign matter from entering the sub-pipe. If laying three sub-pipes, a new cable should be laid. Each person should have 4 hand holes. If laying 4 sub-pipes, put a new optical cable every time. Personal, hand hole 6 only

7. Corrugated hose

Each person, hand hole average 2 meters

8. Plastic pallets, fiber cable hooks

Corresponding to the two methods of deploying optical cables in pipelines, the use of plastic pallets may be based on the actual situation, with a little less estimation. In general, people and hand holes should have plastic pallets.

The other kind is fixed on the wall of the person and the hand hole with the optical fiber hook, and the average one person and the hand hole have only 4 optical fiber cable hooks.

9. Galvanized iron wire

Need a small amount of 1.5, 4.0 iron wire, used for traction head, helper, can be a little estimate,
