(1) the structure, characteristics and performance: ① glass pipe with high strength, light weight, no distortion, smooth inner surface and so on. Its friction coefficient, wear light slippery rope, does not damage the cable. Effective solution to the low intensity of PVC plastic pipe and galvanized steel self-important, easy to scratch the cable when the cable wear shortcomings. The weight of the glass tube with a length of steel pipe is only 1/4, concrete pipe, 1/10, one person can carry. Therefore, transportation convenient, simple construction. Glass pipe ② no galvanic corrosion, non-magnetic, suitable for single and multi-core cables laid, no special treatment to prevent by eddy overcome the problem is easy to produce steel as magnetic vortices. ③ good water resistance, long-term use in wet environments, and composite materials are not ordinary water can only be used in dry environmental conditions. Avoid direct burial cable may cause corrosion occurring, but also to avoid a long period of galvanized steel rust wet conditions, resulting in loss of cable protection. Reached a line segment located in western Sichuan Suining zitong low mountains and hills, close to the Chengdu Plain, rainfall, laying of cable protection measures put forward higher requirements. ④ heat and fire resistance than steel and PVC pipe. FRP cable protection tube can be used in long-term 130 ℃, fire does not burn. ⑤ glass pipe with insulation, anti-corrosion, no rust, long life advantages. Generally up to 50 years without maintenance. (2) the use of FRP pipe: to reach the line expansion and reconstruction project, mainly for other professional and supporting expansion of electrification across the board. To meet the station catenary hard beams and steel columns erected assembly requirements, design of the original station Catenary affect all high and low voltage overhead lines to cable laying. Part of which is located in the path of cable laying hardening off the platform, a portion of the station to the ends of the hair line, near drains and fire water systems are another part of the cable runs across the yard pit road. And because the existing line construction, above the train station every day and night through 13 pairs, of which the vast majority of passenger trains, in order to minimize the impact of construction on the existing line operations caused by the excavation of the site to avoid causing passengers to get off on the course occurs security incidents. Based on the construction site, we conduct a detailed investigation, prior to the measurement cable path well marked, select passenger trains arriving gap, loop unrolling assembly line, with a hardened surface cutting machine cutting site, then the cable trench excavation carried labor organization excavation period that is laying period, followed by backfilling, removal of Dregs, greatly reducing the effective construction time, minimize the impact of construction on operations, has been unanimously praised aspects of the station more: FRP composite Pipeline http://www.zbsyfrp.com car wash FRP grating http://www.hbhhblg.com FRP cable protection pipe http://www.boligang168.com fiberglass grease trap http://www.hbsfblg.com FRP pultruded profiles http://www.hbhq168.com training tower http://www.hsbileita.com
