Next, let's talk about the structural characteristics and construction points of road sound barriers
Structural characteristics of mobile road sound barriers
The mobile road sound barrier includes a sound insulation wall, a support, and a base set at the bottom of the sound insulation wall. The sound insulation wall includes sound-absorbing panels and sound insulation panels arranged side by side. There is a noise reduction partition wall between the sound-absorbing panels and the sound insulation panels. The outer side of the sound-absorbing panel is coated with a flexible crack-resistant mortar layer, and the outer side of the sound insulation panel is coated with a second flexible crack-resistant mortar layer. A noise reduction device is provided at the top of the sound insulation wall, which can filter the noise removed by the sound insulation wall. The support is movably connected to the base via bolts. The bottom of the base has two legs, and the bottom of each leg is connected to a roller. The roller is placed in the track on the base, and the roller can drive the sound insulation wall.
There are many ways to splice highway sound barriers
A type of highway sound barrier with multiple splicing methods, including a support connector. A splicing groove is fixedly connected above the support connector, and a plug is inserted into the splicing groove. A fixing frame is fixedly connected to the side of the plug away from the insertion groove. A sound insulation board is fixedly connected inside the fixing frame. The surface of the sound insulation board is provided with louver holes, and noise reduction foam is sandwiched inside the sound insulation board.
By setting a splicing groove, splicing connection between highway guardrails can be carried out. By setting a limit tube, the plug can be inserted into the insertion groove. A groove hole matching the thickness of the splicing groove is provided between the limit tube and the connecting piece, so that the device can be vertically spliced and can better adapt to complex road conditions.
Winter construction precautions for highway sound barriers
When the average day and night temperature at the highway sound barrier construction site is below 5°C or the low temperature is below -3°C, the concrete pouring project should be handled according to winter construction. According to the specific situation of highway sound barrier construction, determine the specific project or work content that needs protection during winter construction of highway sound barriers, formulate corresponding winter construction protection measures for highway sound barriers, and prepare materials and maintain machinery.
Highway sound barrier construction machinery should be maintained in winter, and the lubricated parts with added water and oil should be frequently checked and replaced to avoid freezing and cracking.
Before entering the highway sound barrier in winter, the construction site should be prepared for cold protection and warmth. Anti-slip measures should be taken for walkways, jumping boards on scaffolding, and workplaces. Concrete should be poured during winter construction and maintenance.
