*Plum Blossom Pipe is a high-quality seven-hole underground plum blossom pipe
Introduction to Plum Blossom Pipe
Plum Blossom Pipe is a plum blossom-shaped communication pipe made of particles as the main material and other formulas through a unique mold. Known as plum blossom tubes and honeycomb tubes, this kind of tube has a smooth inner wall and can be directly used for optical cables, which can save man-hours. Its structure is reasonable, its use value is high and its service life is long. It is mainly used for sheathing tubes of communication cables such as China Mobile, China Railway Communications, China Unicom, China Netcom, and Radio and Television.
Characteristics of Plum Blossom Tube
Plum Blossom Tube adopts porous integrated structure, which has good rigidity and uniform stress. The friction coefficient of the inner wall of the product is small, the cable threading is quick and easy, and the construction is simple and easy. With multiple hole positions, pipe holes can be reserved to improve communication hole utilization. The product has a wide applicable temperature range and can be used in both tropical and cold areas. The joint adopts a socket structure. No tools are needed to complete the connection between pipes, which facilitates construction and maintenance. The service life of plum blossom pipe is more than 3 years under the condition of burial depth. Performance indicators: The color of the pipe is uniform and white. Other colors can be customized according to user requirements. The pipe should be smooth and flat, with uniform color, and no defects such as deformation and distortion are allowed. No cracks, damage or perforations are allowed on the inner and outer pipe walls. Markings should be durable and easily identifiable. _Copy/>_Copy/>
3 Precautions
The buried trench of the pipeline should be as straight as possible according to the design requirements and construction operations. If the bottom of the trench is uneven, a layer of fine sand can be spread. Before burying the pipe, hard objects in the trench should be removed to prevent pipe deformation. When starting to bury the pipe, the porous pipe should be reserved in the manhole for cable threading. The sub-pipe exposed at the end of the manhole should be blocked. When burying the pipe, it is strictly forbidden to mix sediment and foreign matter into the pipe.
For porous plum blossom pipe pipe connections, place the pipe-like positioning ribs upwards, clean the outer wall of the end pipe, insert the direct socket at one end, place a thick wooden board on the end face, and tap the board with a hammer to make the pipe Socket in place. At the other end of the direct socket, insert another pipe directly and socket it in place, and then extend it to the next person's well. In actual construction, the length of each pipe may not be the same as the length between manholes. In this case, measure the length of the pipes according to the actual length of the manhole and cut it with a hacksaw. It must be sawed flat and neatly. After the docking is completed, the end that extends into the manhole must be plugged with a pipe plug to prevent the intrusion of foreign matter.
For those who are installing and using this product for the first time, please do not backfill the soil when laying the first section (the distance between two manholes). Use a cable threader to try through one or two holes. After it goes in smoothly, you can then lay the lower section, which will make you feel more confident.
After the pipe is laid, it should be backfilled with fine sand or fine soil to the height of the pipe. Do not leave the pipe in a suspended state, and then backfill with other soil. It is forbidden to smash large rocks or large dry soil against the pipe.
When the pipeline passes through a section that is severely damaged by external forces, the connecting hole should be covered with cement concrete to ensure its absolute safety.
