What issues should be considered when designing and installing the sound insulation barrier of the railway station?

I will take you to the next sound barrier.

The structure of the sound insulation barrier of the railway station: the sound insulation barrier of the railway station is mainly composed of two parts: the steel structure column and the sound insulation screen. The column is the main force component of the sound insulation barrier. It is fixed on the road anti-collision wall by bolts or welding. Or the embedded steel plate on the side of the track; the sound insulation sound insulation board is the main sound insulation falling noise member, which is fixed in the H-shaped column groove by a high-strength spring clamp to form a sound insulation barrier.

The sound insulation barrier of the railway station is divided into louver sound barrier, micro-hole sound barrier, factory noise barrier, road noise barrier. Most sound barriers use sound-absorbing and sound-insulating hybrid products. The characteristics of this type of product are noise on the road. The occurrence and transmission characteristics are controlled in a targeted manner. For example, if the car and the road conflict or the locomotive and the track conflict sound in the lower part of the road, the sound has the characteristics of the upper part of the screen, so the upper and lower sound absorption and the center sound insulation structure are selected in the plan, which can effectively weaken the noise. The center of the sound barrier uses a transparent reflective sound insulation board to effectively stop the transmission of sound waves; it also provides an open view environment for drivers and residents.

In addition to the elements of the general sound insulation barrier planning device, the railway sound insulation barrier, the outstanding sound insulation barrier and the environmental ecological harmony planning concept, focus on the sustainable development of the landscape, so that the landscape planning gives the sound barrier a deeper civilization connotation. The planning concept, scheme form and data selection status of railway sound barrier are analyzed, and the landscape planning guidelines, appearance planning, data selection, color selection, coordination and transition with surrounding landscape are discussed. Some considerations have been put forward
