Tel: 18732825015 QQ: 2802145516 Ali Want: apchengyang: 011 sales, the cost is low: only low production costs, and because the product is light weight can significantly reduce the load bearing elevated light rail, elevated road, reduce project cost; two, to withstand wind Dutch strong: high strength, light weight, can meet the different climatic conditions on wind load requirements of each region; 3, superior acoustic performance: average noise magnesite sound barrier is greater than 35dB, the average absorption coefficient greater than 0.84 to meet the various fields the sound barrier requirements; 4, fire performance: Magnesite cementitious material is a non-combustible inorganic materials, sound-absorbing glass wool composite, perlite and other materials also have good fire performance, making the product has excellent fire performance, is a national A level non-combustible material; 5, the use of durability: Magnesite sound barrier water-resistant, fire-resistant, corrosion-resistant, anti-UV, from rain, snow, wind and sand erosion and other inclement weather, long life; 6, easy to install: Ling Magnesium sound barrier, light weight, can be fabricated construction, high efficiency, short duration, can save a lot of labor costs; 7, aesthetic plastic: Depending on the needs of the metal can be in the form of structural materials and translucent material combinations can also be painted in different colors and patterns to meet the requirements of decorative landscape. 8, energy saving and environmental protection: the sound barrier magnesite raw materials used non-toxic, and the production process without high heat, no toxic gas release, the state encourages the development of environmentally friendly products; 9, broad scope of application: Depending on the needs of machine production Ling soundproof panels and magnesite magnesium acoustic panels, suitable for road transportation, rail, railway, culverts, tunnels, and various industrial plants, workshops and residential quarters, and other fields. 1. roadbed built on the basis of sound barrier should be synchronized with the construction of roadbed, not because of its construction and damages, roadbed stability and security. Foundation construction should sound barrier in the road after the basic body shape, before laying the track and cable trench construction; before construction on the embankment should identify the location of all types of pipeline; based on the basis of the size and location of the sound barrier on the hard shoulder grooving cut, cut open When the tank is prohibited destruction of various types of pipelines. 2. The basic design requirements should sound barrier position, shape, size, depth, construction, foundation excavation subgrade surface shall not be destroyed. 3. Sound Barrier foundation laying anchor, anchor hole grouting materials used in construction, construction methods should be consistent with the design requirements, shall not affect the security and stability of the roadbed. The foundation design requirements should sound barrier construction joints. The foundation of every sound barrier 20m ~ 30m long set an expansion joint. Construction should be combined with the location of the site topography to determine the specific joints. 5. sound barrier design requirements should be embedded foundation drains, drain outlet shall scour the roadbed; and non-ballasted track line between the sump drain at the intersection of concrete foundation may destroy drain. Each top 2m embedded foundation ?100mmL shaped PVC pipe to the inside of the shoulder drainage sound barrier surface; variable cross-section at the middle of each base by 2% slope 4m embedded ?75mm straight PVC pipe to drain water seepage and primitive way cable channel drain ; among non-ballasted track roadbed wire line connections sump drains in the foundation can be poured. Roadbed sound barrier drainage facilities should be located, outside of the drain outlet should avoid generating embankment slope erosion and prevent sound leakage. 6. After all the sound barrier with the pouring of concrete foundation dense, its surface smooth surface should converge with the roadbed. 7. Sound Barrier foundation concrete strength tests shall comply with the provisions of Article 11.2.18 Standard. 8. sound barrier base and cable ducts, catenary between the pillars, and the shoulder surface cracks etc design requirements should be applied waterproof layer. Foundation and cable trays, catenary between the pillars, and the shoulder surface cracks etc do waterproof layer of asphalt concrete applications. 9. sound barrier line basis from the centerline, cross-sectional dimensions, buried depth of tolerance, the number of tests and test methods should be consistent with the requirements of Table 13.4.9. |
