Rising Waters, Rising Solutions: How Sibom's Manhole Milling Machine Combats Urban Flood Risks

Entering 2025, a climate phenomenon that is affecting the entire world is the El Niño event that has already occurred. The emergence of El Niño is one of the main factors influencing weather patterns globally.

The first image would typically show normal oceanic and atmospheric conditions, where trade winds blow westward across the Pacific Ocean, helping to pool warm surface water near Asia and allowing cooler waters to rise near the Americas.
The second image, representing the El Niño phenomenon, would depict these trade winds weakening or reversing. This change leads to warmer surface waters shifting eastward toward the central and eastern Pacific, altering weather patterns globally and often causing increased precipitation in normally arid regions and drought in typically wet regions.

 

El Niño, which means "The Child" in Spanish, specifically refers to the large-scale, prolonged abnormal warming of ocean waters in the eastern and central equatorial Pacific. It has the following characteristics:

  1. Minor changes in ocean temperatures can lead to significant changes in atmospheric temperatures.
  2. Although El Niño originates in the ocean, it can cause anomalous weather and climate conditions globally.
  3. El Niño events typically occur every 2 to 7 years.

Even though this event is categorized as a weak El Niño and is considered a transient phenomenon, its impact on the North Pacific coast has already become apparent. Since this spring, there has been a significant increase in precipitation along much of the North Pacific coast.

According to meteorological experts, the flood prevention situation along the Pacific Rim is quite severe this year. Extreme weather and climate events are occurring more frequently, and meteorological disasters are more severe.

Efforts to minimize the damage from flooding and ensure the safety of the populace are currently urgent tasks facing many departments. Urban flooding and preventing inundation in cities are crucial issues. When urban areas experience internal waterlogging, various safety hazards can easily arise. Among the risks that need to be identified, one area that requires special attention is the manholes.

special attention

Various manhole facilities in municipal networks, such as those for stormwater, telecommunications, fiber optics, and other municipal services, play a crucial role in urban functionality. However, due to differences in the material composition of asphalt and concrete structures of road covers compared to the base and surface layers of roads, combined with issues in design and construction, the asphalt and concrete around manhole covers are prone to wear and tear.

wear and tear

When rainwater seeps into the road base through cracks, the repeated rolling and vibration from vehicle traffic can easily damage the asphalt structure adjacent to manhole covers and the underlying road base. This can lead to the deterioration of the road surface structure around the manhole, causing it to settle and the manhole frame to become loose.

The wear and tear of manhole covers have become a persistent problem in cities, posing safety risks to residents' daily commutes.

Therefore, maintaining manhole covers is one of the fundamental tasks in municipal engineering projects across various regions. However, repairing the road surface around manhole covers is complex and labor-intensive, making traditional manual construction methods very time-consuming. As a result, many cities opt to carry out these repairs at night to avoid disrupting traffic flow. How to efficiently conduct large-scale manhole cover repairs remains a common challenge faced by municipal units at all levels nationwide.

Thus, the manhole cover milling machine has emerged. This machine is a specialized piece of equipment for inspecting and maintaining urban road manhole facilities. It can quickly identify various issues with manholes and rapidly remove the frames around manhole covers to facilitate the re-pouring of concrete. This equipment not only significantly enhances work efficiency but also greatly improves the quality of construction. Additionally, it greatly improves the smoothness and aesthetic appearance of the road surface.

The Sibom manhole cover milling machine, produced by Sibom Engineering Machinery Manufacturing Co., Ltd., utilizes the hydraulic supply system of a loader or skid-steer loader to perform milling operations. It can cut through asphalt and concrete, and with the help of a locator, it can remove most well frames within 3-4 minutes, making the milling operation straightforward and easy to manage.

The machine is equipped with shields to prevent cutting debris from splashing and injuring pedestrians and vehicles. It features cutting diameters ranging from 680 to 900 mm (suitable for skid-steer models) and 1300 mm (suitable for 5T loaders). After milling, the area matches the shape of the manhole cover, ensuring a precise fit.

The milling teeth of the Sibom manhole cover milling machine are made from alloy materials, which offer high strength and durability, allowing them to adapt to different road materials. They not only possess rapid cutting capabilities but also excellent impact resistance and bending strength. Under normal conditions, the milling teeth can perform 100-200 cuts. The springs of the manhole cover milling teeth are made from high-elasticity materials, providing high resilience and strong expansive force, capable of withstanding prolonged expansion forces. Additionally, the Sibom manhole cover milling machine is equipped with a cooling device that effectively cools the cutting tools, extending their service life.

The Sibom manhole cover milling machine streamlines the process by combining positioning, excavating, and cleaning into a single operation, saving both time and effort. After repairs, the manhole cover is leak-proof and remains level with the road surface. Typically, using the Sibom manhole cover milling machine for manhole cover repair work can be completed in about an hour.

The Sibom manhole cover milling machine offers the following advantages:

  1. Rapid Mobility and Powerful Performance: It can quickly reach the construction site and swiftly mill the manhole cover, reducing the time roads are closed. This efficiency has garnered widespread praise within the industry.
  2. Circular Protective Cover and Water Spraying Device: These features allow the machine to operate with low noise and minimal dust, enhancing the working environment.
  3. Efficient Milling Design: The milling machine creates an annular trench with neat upper edges and a tapered lower section. This design requires less asphalt concrete to fill, resulting in a uniformly shaped, aesthetically pleasing circular repair mark.
