These types of manholes are about two to three feet or 75-90 centimeters of shallow depth. They are normally placed at the starting of a sewer or drainage water conduit passage and in the areas that are not subjected to heavy traffic. These types are suitable for maintenance work and are also known as inspection chambers with a light lid as a cover at its end.
Flexible traffic posts are also cost-effective compared to traditional traffic management solutions. Their ability to be relocated and repurposed means that they can be used for various events or changes in traffic patterns without incurring the costs associated with permanent installations. Additionally, the implementation of updated technologies often leads to enhanced efficiencies, which can translate into long-term savings for city governments.
