What Are Noise (Wind) Barrier Embedded Plate Parts?
The embedded plate part for noise and wind barrier refers to the pre-fabricated steel plate welded with steel rebars or installed with anchor bolts and U-shaped bolts for embed foundation. They are the key steel base structure for wind and noise barrier columns, together with noise and wind reduction wall panels, which offer an excellent effect of noise and wind reduction.
In noise and wind barrier construction, embedded plate parts are the key element for maintaining stability and seismic performance. Using these part can also reduce total construction time and project costs.
Noise and Wind Barrier Structure
The main function of noise and wind barrier columns is to support the entire barrier structure. A noise or wind barrier typically consists of multiple columns and connecting beams, vertical members, and other structural elements. As the support points of the noise and wind barrier, the columns must withstand the weight of the entire barrier and the forces exerted by the external environment; therefore, they must possess sufficient strength and stability.
Embedded Plate Structure Design
- The selection of embedded plate part for noise and wind barriers varies due to their different force-bearing requirement, and their selection directly impacts the barrier’s performance and lifespan. Their main parts are embedded steel plates, anchor bars and gaskets, etc.
- The embedded steel plates is the support element for noise barrier bottom plate; anchor bars and bolts secure the embedded part to the concrete base; the gaskets adjust the distance between the steel plates and the foundation, these components work together to ensure the stability and safety of the barrier column.

- Installation Instructions
1. In the prefabrication of noise (wind) barrier panels, according to the requirements of the construction drawings, the pre-embedded holes and templates need to be installed first.
2. If using U-bolts other than welded rebars, the U-bolts must be aligned in position before binding or welding.

Embedded Plate Part Production Process
The production of sound (wind) barrier embedded plate part starts with the raw materials ( U-bolts, rebars and steel plates ). After raw material inspection, followed steps are steel plate cutting, drilling, degreasing, and marking, the steel plates goes through the surface treatment stage, which involves shot blasting, zinc coating, leveling, passivation, and baking. Finally packed and stored after the finished product inspection.

Installation of Wind Barrier Embedded Part
The following factors should be noted when installing the embedded plate part of the noise barrier. embedded part for wind barrier is mostly the same:
- The embedded plate should be embedded into the predetermined embedded groove, then pour the concrete to ensure stability.
- The installation location, shape, size, and depth of the embedded plate part should be strictly constructed in accordance with the design requirements.
- During installation, prevent any damage or deformation for all components of the embedded plate part.
Features of Embedded Plate Part of Noise & Wind Barrier
Pre-embedded plate part for noise or wind barriers are crucial parts used in H beam column installation, the selection can directly affects the performance and service life of the noise and wind barrier. Here are the features and benefites:
- Prefabrication: The embedded plate part of the noise barrier are prefabricated noise insulation materials that can be made in advance before the noise barrier is installed, thus improving construction efficiency.
- Noise/wind insulation: As an important component of the noise barrier, the embedded plate part of the noise barrier have good noise or wind insulation effect and can effectively reduce noise pollution.
- Stability: The embedded plate part are fixed to the foundation of the noise barrier by anchoring steel bars, which ensures the stability and safety of the noise barrier.

How to Choose Embedded Part for Wind & Sound Barriers
In construction of railway lines and bridge, wind barriers and noise barriers are designed as 2 independent systems. Railway construction companies must strictly adhere to their respective drawings and must never use embedded components from noise barriers for wind barriers, as this would create serious safety hazards. However, wind barrier embedded plate part can be used for the installation of noise barrier columns for their higher strength level.
Barrier Parts Compare – Wind Barrier and Noise Barrier
| Barrier Parts | Wind Barrier | Noise Barrier |
|---|---|---|
| Barrier Support column (H-beam) | Larger dimensions, thicker plates, and higher strength. Larger H-beams (such as HM440×300×11×18) are typically used to ensure that their bending and shearing resistance | The dimensions are relatively small and the material usage is less. The H-beams used are usually smaller (such as HM350×250×9×14). |
| Embedded plate part (anchor bolt assemblies) | There are more anchors, they are thicker in diameter, and they are anchored for longer lengths. For example, 8 or more high-strength M36 or M42 anchor bolts or U bolts may be used, | The number of anchors is small, and their size is small. For example, 4 or 6 M24 or M30 anchor bolt may be used. |
| Flange & stiffening ribs | The flange steel plate is thicker, and the stiffening ribs are more numerous, denser, and thicker to enhance the rigidity and strength of the joint area and prevent deformation under huge loads. | The flange and stiffening ribs are relatively lightweight. |
Wind Barrier Features
- Core Function: To resist strong crosswinds and prevent train derailment, which is directly related to driving safety.
- Load Bearing: Primarily bears enormous wind loads. This load is the controlling load, meaning it is the most important and dangerous force considered during the design phase. The wind barriers for China’s high-speed railways need to withstand once-in-a-century strong winds, with extremely high wind pressure values.
- Safety Level: It belongs to the category of life safety engineering, and its structural reliability requirements are extremely high.
Noise Barrier Features
- Core Function: Reduce noise and protect the environment along the route; it is an environmental protection project.
- Load Bearing: It also bears wind loads, but its design wind pressure value is usually much lower than that of the wind barrier. In addition, its own weight and the wind pressure fluctuations (wind pressure ripples) of the train must also be considered.
- Safety Level: Although safety is also required, the direct consequences of its failure are noise pollution or damage to the barrier itself, which usually does not immediately lead to train accidents. Therefore, the safety level requirement is relatively lower than that of wind barriers.
