In the construction of communication pipe network, PVC corrugated pipes and PVC honeycomb pipes are widely used at present, and plastic-coated steel pipes or galvanized steel pipes are used for crossing the street and leading pipes, and the total length accounts for about 10%-20% of the total pipeline scale. Because the use of crossing the street and guiding pipes is less, we compare the commonly used PVC corrugated pipes with PVC honeycomb pipes and glass steel pipes to illustrate our ideas.
The most direct sentence of this idea is: replace PVC corrugated pipe with FRP communication pipe and replace PVC honeycomb pipe with FRP honeycomb pipe.
Reason for replacement
At present, the construction of communication pipelines is accompanied by the construction of urban roads, which are generally laid under sidewalks. With the modernization process and economic development of this city, sidewalks are no longer just roads for people to pass, private cars will stop, and even heavy vehicles will pass in the early stage of development, which will make the communication pipe network buried under sidewalks generally collapse due to overload, causing the destruction of communication pipes, thus affecting the safety of communication networks.
Secondly, in the process of urban construction, the reconstruction of old cities and the development of economic zones all involve the reconstruction of roads and the construction of heavy machinery near roads. Due to the limitation of strength and rigidity, PVC pipes buried in the ground are easily damaged by these working machines, and the optical cables inside are also cut off.
Thirdly, because the PVC pipes purchased by communication operators in different provinces have different fillers or filler addition and wall thickness, the quality is quite different, and they are easy to crack, age and change color. Some provincial companies also use PVC pipes to lead pipes, which are destroyed and burned by human external forces. Bare optical cable can be seen at the front end of the pipeline, which is easy to be cut off.
Finally, to sum up, it is a better choice to replace PVC with a material with good chemical stability and excellent mechanical properties. Glass fiber reinforced plastic communication pipe and glass fiber reinforced plastic honeycomb pipe came into being.
Glass fiber reinforced plastic communication pipe and glass fiber reinforced plastic honeycomb pipe have the characteristics of high strength, light weight, no corrosion and extremely stable chemical stability. And the manufacturing process is simple and will not cause environmental pollution. After the product is laid, the construction of pipeline cushion, concrete package and brick-concrete protective layer will be reduced, and it will be laid quickly in response to the call of national energy conservation and emission reduction. Compared with ordinary PVC laying, they can save 2/3 of the time by waiting for the cement package to dry before backfilling, and the exposure time of pipeline excavation is short, thus avoiding traffic congestion and pedestrian safety. The service life of pipelines laid at the same time is 25-50 years. In acidic soil, ordinary PVC pipes will become brittle, deformed and cracked in 3-5 years, and the service life of FRP pipes mentioned here is at least 25 years.
Glass fiber reinforced plastic communication tube is the earliest concept of communication tube put forward by Chongqing William Company, which is different from the common glass fiber reinforced plastic cable protection tube in the market. At the request of the patentee, the specific manufacturing process has not been disclosed to the public at present;
Glass fiber reinforced plastic honeycomb pipe takes into account the traditional structure of PVC honeycomb pipe, ensures the content of sub-holes in the pipe, and takes into account the high strength and impact resistance of glass steel pipe, which is a balanced combination of cost and strength. Chongqing William Company has been fully authorized by the patentee for three years.
The company is only responsible for patent technology cooperation and technology promotion, and is not engaged in product manufacturing and marketing. Enterprises, institutions and individuals interested in entering the communication field can contact William Company.
Any expert familiar with the communication industry can generally know that if FRP communication pipes and FRP honeycomb pipes are widely used, the purchase volume of a medium-sized provincial company is about 1500 km. If a province is calculated by three operators, the purchase volume is nearly 3000 kilometers, which means the output value is about 300 million, and the national output value is nearly10 billion. With the process of urbanization and the deepening of township pipelines, this application will be more and more extensive, and it will also bring greater industrial development.
It is this application that will greatly reduce the pipeline damage rate, avoid repeated excavation of pavement, and prolong the service life by more than 5- 10 times, benefiting the country and the people, and benefiting future generations.
