Product details
Construction of highway sound insulation barrier: High-speed sound barrier is mainly composed of steel structure column and sound absorption screen. The column is the main stress component of sound insulation barrier. It is fixed on the road anti-collision wall or the embedded steel plate beside the track by bolts or welding. The sound absorption board is the main sound insulation component to reduce noise. It is fixed in the H-shaped column groove through high-strength spring clips to form a sound insulation barrier. What are the ancillary functions of high-speed sound barrier?
With the protection function of sound insulation barrier engineering for sound sensitive points along highways and railways being generally recognized and accepted by the whole society, it is not only used to block sound wave propagation, but also an outdoor noise reduction facility. It is more of an urban building. The aesthetic requirements of sound insulation barrier are getting higher and higher. High-speed sound insulation barrier generally adopts transparent glass in the middle, which not only has good transparency and beauty, but also sprays various colors on the surface, which can help drivers adjust eye fatigue and coordinate with the surrounding environment
There is also a high-speed sound barrier that can be installed with small wind turbines. Billboards indicate road signs. Under the premise of not affecting its main use functions, the ancillary functions are various!
After several years of use, a small part of the high-speed sound barrier needs to be maintained and replaced, but because the replacement generally occurs during traffic operation, the security measures are particularly important during construction and replacement. For example, when replacing the screen materials of highway sound insulation barriers in traffic sections, it is necessary to formulate a complete construction safety protection scheme. The construction site should try to avoid the driveway at the same time. At least 200 meters away, it is necessary to set up construction guardrails and warning signs and all other signs and signs required for highway construction, and construction workers must wear clothing with reflective signs, etc. There is also a need to send special personnel to dredge vehicles; Try to avoid night construction
