The drainage of railway & subway infrastructures involves the efficient management of water that can accumulate both on top of and below the railway & subway track. This proper water management is crucial to avoid potential issues that could compromise the integrity and safety of the railway infrastructure, such as flooding and erosion of the ballast bed. These erosions can weaken the base on which the railway rails are seated, putting the stability of the embankments at risk and, ultimately, the safety of the railway system as a whole.
The accumulation of water on railway tracks can have various causes, including heavy rains, snowmelt, or rising groundwater levels. If not managed properly, this accumulation can lead to the saturation of the ballast, which is essential for the stability of the rails and the uniform distribution of loads. Erosion of the ballast not only reduces its bearing capacity but can also cause shifts and deformations in the tracks, increasing the risk of derailments.
In the case of the rails, there are two main types of drainage that can be implemented on the railway track: open drainage and buried drainage. Open drainage generally refers to visible ditches and channels that collect and divert surface water. This type of drainage is easy to inspect and maintain, allowing for the quick identification of blockages and issues. However, it can be less aesthetic and more susceptible to the accumulation of debris and vegetation.
On the other hand, buried drainage consists of pipes and underground systems designed to manage water that seeps through the soil and railway ballast. This type of drainage offers the advantage of being protected from external factors and having a lower visual impact on the landscape. However, its installation and maintenance can be more complex and costly.
The use of drenotube® in the railway & subway track drainage system presents multiple advantages. This innovative system is designed to protect the substrates of the railway structure, ensuring that water is efficiently evacuated away from the critical area where the rails and ballast of the railway track are located. The implementation of drenotube® helps to keep the ballast bed dry, which in turn preserves its support capacity and reduces the need for frequent maintenance.
Furthermore, drenotube® is easy to install and maintain, making it a practical and economical option for railway infrastructure projects. Its flexible and durable design allows it to adapt to various terrain and load conditions, ensuring optimal performance in the long term. By guaranteeing efficient water management, drenotube® significantly contributes to the stability and safety of the railway tracks, minimizing the risks associated with water accumulation and erosion.
In summary, effective drainage is fundamental for the stability and safety of railway infrastructures. The use of systems like drenotube® not only protects the substrates and ballast but also ensures proper water evacuation, avoiding major problems and contributing to the smooth operation of the railway network. By implementing efficient drainage solutions, the lifespan of railway infrastructures can be prolonged, ensuring the safety and efficiency of rail transport.
