Urban Landscape sound barrier sound barrier material manufacturers choose the general principle is good noise reduction performance, structure safe, reliable, affordable materials, low installation cost, durable, long life, landscape coordination, nice and so on. Specifically as follows: (1) a large amount of noise: the average amount of noise should not be less than 35dB; (2) the sound absorption coefficient is high: the average absorption coefficient should be not less than 0.84; (3) weather Durability: The product should have a water resistance heat, UV, temperature changes will not degrade the performance of stormwater quality or abnormal. Products using aluminum coil, galvanized coil, glass wool, H galvanized steel column surface outside the grounds of anti-corrosion life of more than 15 years. (4) appearance: choose a variety of colors and shapes are combined, coordinated with the surrounding environment, the formation tapestry. (5) Economy: prefabricated construction, improve work efficiency, shorten construction time, saving construction costs and labor costs. (6) Convenience: parallel with other products to install, easy to maintain, easy to update. (7) Light: acoustic panels series has the characteristics of light weight, reduce the load bearing elevated light rail, elevated road, can reduce the cost structure. (8) Fire: The superfine wool, because of its high melting point, non-flammable, fully meet the requirements of environmental protection and fire code. (9) High intensity: a combination of different regions of the climatic conditions, structural design fully into virtual wind loads. Increase the strength of the recess by pressing production line. (10) waterproof, dustproof: material designed to fully consider the waterproof, dustproof, dust or rain environment in its sound absorption performance is not affected, construct drainage measures have been set for dust, avoid stagnant water inside components. Resonant cavity micro-perforated sound absorption in the rain sound absorption performance is not affected environment for low-frequency noise is particularly evident. (11) Durable: product design has been fully taken into account wind load road transport vehicle crash safety and full gas fake outdoor corrosion. Products using aluminum coil, galvanized coil, glass wool, H galvanized steel column surface. No corrosion within the warranty period, the same type, sound absorption, sound insulation effect is not reduced. An embankment 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. Two basic design requirements should sound barrier location, shape and 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. 4 basic 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 be avoided LO company "leading technology, quality win" business philosophy, with nearly a hundred senior professional and technical personnel, with strong R & D and technological innovation capacity, with large CNC and other automated production equipment more than 80 pieces (sets), using the most advanced production technology and production processes, the implementation of total quality management. Over the years my company's technology and product quality in the industry has been in a leading position. Long with large domestic oil, coal, municipal transportation and other units to maintain good relations of cooperation, and establish a good trade with over 70 countries the United States, Japan, Russia, Australia and so on. Huasheng Metal Mesh Products Co., Ltd. will continue to adhere to the "customer first, good faith," the purpose of continuous innovation, cooperation and win-win spirit, forge ahead, the challenges of tomorrow.
