HDPE quincunx tube five hole quincunx tube seven hole quincunx tube manufacture

Seven hole plum blossom tube is a kind of plum blossom shaped communication tube, also known as plum blossom tube and honeycomb tube, which is formed by taking particles as the main material and other formulas through a unique mold
The inner wall of this kind of tube is smooth, can directly wear optical cables, can save man hours, has reasonable structure, high service value and long service life
The utility model is mainly used for protecting sleeves of communication cables such as mobile, China Railway, China Unicom, China Netcom, radio and television, etc
The buried trench of seven hole plum blossom pipe shall be as straight as possible according to the design requirements and construction operation
If the trench bottom is uneven, a layer of fine sand can be paved
Before burying pipes, the hard objects in the trench shall be removed to prevent pipe deformation
When burying pipes, 10-15cm perforated pipes shall be reserved in the manhole for cable threading
The sub pipe exposed at the manhole end shall be blocked
When burying the pipe, it is forbidden to mix sediment and foreign matters into the pipe
For pipe connection, place the pipe like positioning bar upward, clean the outer wall of the end pipe, insert the socket at the direct end, pad a thick wooden board on the end face, and knock the plate with a hammer to make the pipe socket in place
At the socket of the other end directly, insert another pipe directly and socket it in place, and then extend it to the next manhole
In the actual construction, the length of each pipe is not necessarily the same as that between manholes
In this case, measure the length of the pipe according to the actual length of manholes, and cut it off with a hacksaw, which must be sawed flat and neat
After the butt joint is completed, the end extending into the manhole shall be plugged with a pipe plug to prevent the intrusion of foreign matters
If this product is installed and used for the first time, do not backfill before laying the first section of the distance between two man wells
It's safe to use the threading device for two sections of cable, and then it can be laid down smoothly
After the pipe is laid, it shall be backfilled with fine sand or fine soil to the height of the pipe
The pipe shall not be suspended, and then other soil shall be backfilled
It is forbidden to smash large stones and large dry soil blocks into the pipe
When the pipeline passes through the section seriously damaged by external force, the hole connection part shall be covered with cement concrete to ensure its absolute safety
