Drainage is very important in the design of a road infrastructure. In fact, this has become one of the technical requirements for road infrastructure that must be met. Be it public roads, toll roads, flyovers or overpasses, or bridges. The road drainage mechanism itself is by channeling water (rainwater, waste water, or groundwater) to a designated disposal site.
The aim is none other than to prevent the pavement from being damaged due to puddles of water. In other words, this keeps the road body dry, which in turn is useful for increasing the comfort and safety of road users in using the road infrastructure.
In general, the road drainage performance is supported by 2 types of surface drainage structures, namely gutters and culverts. The function of the two buildings is as a waterway to the discharge outlet by seeking the force of gravity so that the construction follows the contours of the road. In addition, there are also components that support road drainage buildings that are mandatory and we usually encounter on the streets.
What are the components of the road drainage?
Here are some of them:
Water catch grill
A catchment grill is a component in the form of square, rectangular, and circular metal plates that have holes in their surface to allow water to enter. This component can usually be opened and closed because it has 2 parts in the form of a frame and a cover. The installation of this water catchment grill can be found on the surface of roads, parks, sidewalks, residential areas, and other public spaces.
Grating
Grating is a drainage component that is used to cover the concrete/precast gutter that insulates the land. The most common shape is a rectangle with a hole for the water filter. This grating is also often referred to as a pedestrian crossing on a drainage channel whose presence will allow people around to cross to the road surface separated by a ditch comfortably and safely.
Street inlet
This drainage component has a shape that is also similar to the previous drainage inlet. In general, street inlets are rectangular in shape with rectangular filter holes. However, this street inlet is more specifically for placement on the sides of the road to accommodate and distribute rainwater runoff along the road. So usually the thickness is lower when compared to gratings and grills that can withstand traffic loads.
Deck drain
If on a public road the collection and drainage of surface water runoff is the task of the inlet drainage grill, grating and street inlet components. So toll roads, flyovers, bridges which are non-level road infrastructure have a special component called deck drain to support the drainage function. Deck drain has a shape whose top resembles a drainage inlet. It's just that what makes it different from other drainage inlets is at the bottom in the form of a tube that will be connected to the drain pipe.
Manhole cover
Another very important drainage component installed on the road is the manhole cover. This manhole cover is used to cover the underground drainage channel control tub hole. Without this component, the control tub hole/manhole/culvert hole left open can certainly threaten the safety of road users. In addition, this is the entry point for officers to enter the subsurface drainage channel in order to carry out maintenance to ensure the water drainage performance runs as it should. In terms of the physical unit, the manhole cover has a shape that is basically similar to a catchment grille. That consists of 2 parts, including the frame and cover, but the surface of the manhole cover usually does not have water filter holes.
These are some of the components of road drainage, all of which have a vital role in supporting the optimal performance of the urban drainage system. In the procurement of these components, the quality side must be considered because it is closely related to the security and safety of road users. Components must have high resistance to traffic loads as well as outdoor weather conditions. And not infrequently also needs to be considered in terms of design to add to the aesthetics of urban planning.
