2021 is the first year to comprehensively accelerate the construction of a powerful transportation country. In order to grasp the new development stage, implement the new development concept, practice and build a new development pattern, strive to realize the transformation of the road network management mode from extensive to intensive and refined, promote the transformation of the "one network" operation mode of expressway from low efficiency to high quality, gradually realize the optimization and upgrading of road network resources, improve quality and efficiency, and effectively improve the traffic efficiency and service level of the road network, To improve the development level of expressway informatization, exchange and discuss the relevant management and technical issues under the operation of "one network" of the national expressway, strengthen the experience and technical exchange among peers, and promote the application of new technologies and new products, the China Highway Society will hold the 23rd China Expressway Informatization Conference and Technical Products Exhibition (CEIC-2021) at Suzhou International Expo Center on April 22-23, 2021.

At the invitation of the organizer, Jingzhou Liangcheng Technology Co., Ltd. (hereinafter referred to as Liangcheng Technology) took the newly developed functional products to the exhibition to show the new technologies and functions of the optical communication protection pipeline system! Thanks for your constant support, Liangcheng Technology would like to express its most sincere thanks! You are specially invited to visit the venue and guide the work! Booth No.: Hall E3 B51.

Liangcheng Technology is a national high-tech enterprise specializing in plastic pipe design, production, marketing and installation services. Located at No. 6, Tieniu Road, Yanjiang Industrial Park, Jiangling County, Hubei Province, with a registered capital of 60 million yuan and an area of 70000 square meters, it has the comprehensive capacity to produce 12000 tons of plastic pipes and composite pipes annually. The main products are: HDPE silicon core pipe, high-performance cluster microtube, PE sub-pipe, perforated plum pipe, double-wall corrugated pipe, MPP power pipe, PE water supply pipe, gas pipe, steel-plastic composite pipe, etc. The products are widely used in communication, power, urban underground pipe gallery, water supply and drainage, farmland water-saving irrigation and other fields. Communication pipeline products cover all regions except Hong Kong, Macao and Taiwan. The "silicon core tube" product has won the first place of "China's top ten brands of silicon core tube" for two consecutive times, and the first "transportation product certification" winner of silicon core tube and cluster tube of the Ministry of Communications.

Product introduction:

Glass fiber rat-proof silicon core tube

This product is a composite glass fiber rat proofing layer with a multi-layer co-extrusion structure added in the middle of the pipe, which is composed of a high-density polyethylene (HDPE) outer layer and a permanent solid silicon inner lubricating layer (referred to as the silicon core layer). The middle layer is an environment-friendly glass fiber composite material, and the outer layer is generally with a color bar, which makes the rats have a certain sense of fear of such pipes and achieve the rat proofing effect.

In order to protect scientific research achievements and its own intellectual property rights, Liangcheng Technology applied for an invention patent for "a production method of rat proof silicon core tube", patent number: ZL 202011388544.1; "A production device for rat-proof silicon core tube" and "a co-extrusion die for rat-proof silicon core tube" have been applied for utility model patents respectively, with patent numbers of "ZL 202022849649.4, ZL 202022849645.6". The enterprise standard "Composite glass fiber rat-proof high-density polyethylene silicon core pipe and underground pipe gallery communication pipe" Q/JZLC03-2020 was issued, which stipulated the technical parameters and physical performance inspection requirements of HDPE rat-proof silicon core pipe and HDPE underground pipe gallery rat-proof communication pipe.

Self-supporting perforated bundle tube

This is a special bundle tube that can be laid overhead. The product has four major advantages: first, it can better protect the overhead communication optical cable, and can use the micro optical cable in the bundle tube that is laid overhead to carry out multi-hole cable blowing; The second is that the optical cable is not affected by the external environment and load in the bundle tube, and has better insulation, anti-static and anti-ultraviolet radiation performance; Third, reduce the installation cost of optical cable and improve the construction efficiency; Fourth, reduce the optical fiber transmission loss, which is helpful to improve the transmission quality. This product has been granted a utility model patent by the China National Intellectual Property Administration. The patent name is "an overhead silicon core pipe", and the patent number is ZL202020420639.6.

Tracer silicon core tube

This is a reliable and technologically mature positioning method for underground network silicon core tubes. A sheathed copper wire with high conductivity is synchronously produced on the outer wall of the entire silicon core tube to provide response marks. It makes construction detection more convenient and accurately describes the direction and location of polyethylene silicon core pipe, saves the time and cost of line maintenance and line expansion, facilitates accurate positioning during network operation and maintenance, and effectively avoids pipeline damage or damage to other facilities caused by construction dislocation. It can be detected with conventional instruments, and its service life is not less than 50 years.

This product is authorized by the China National Intellectual Property Administration for invention patent. Patent name: "A silicon core tube production process with information wire", invention patent number: ZL 2018 11104121.5.

Environment-friendly flame-retardant silicon core tube

In order to meet the needs of the market, Liangcheng Technology has developed a new type of "environment-friendly flame-retardant silicon core tube" by adopting a unique processing technology in the production process of ordinary silicon core tubes. It not only has excellent mechanical and physical properties of ordinary silicon core tube, but also has high flame retardancy; When encountering combustion, the halogen acid will not be released and will be extinguished immediately after the open fire, which can reduce the emission of a large number of toxic and harmful gases and corrosive gases and the generation of smoke; The insulation resistance changes little after immersion, which has high safety and reliability.

With the enhancement of people's awareness of environmental protection, safety and health, Liangcheng Technology has adopted self-made environment-friendly composite flame retardant in the development of flame-retardant silicon core tubes, and achieved good results. This product is widely used in the cable protection engineering of the national power department in the construction or reconstruction of the original facilities, as well as the cable protection sleeve in the municipal, road and communication engineering with fire and flame retardant requirements.

It was granted an invention patent by the China National Intellectual Property Administration. The patent name is "a production method of environment-friendly flame-retardant silicon core tube", and the invention patent number is ZL 201910400315.8.

Aluminum-plastic composite porous bundle tube

In order to improve the radiation protection effect and buffer performance, Liangcheng technical personnel also developed and invented an "aluminum plastic composite porous bundle pipe", which is a "optical cable bundle pipe" and its production molding equipment, "an aluminum strip forming device for the bundle pipe", which were respectively authorized by the China National Intellectual Property Administration for utility model patents with patent numbers of ZL 2017 2 1048484.2 and ZL 20172 1048621.2.
