In most of the construction sites and rural homes, there are trenches of seasonal or permanent streams or rivers or where there are big utility lines. Linking opposite sides of the stream or trench require a construction of a culvert to allow for ease crossing over without interfering with the flow of water or utility lines. A culvert refers to an enclosed underground tunnel for conveying water or used as a runaway. The culvert is thus very important in constructing across rivers and streams.
Types of culverts
Many different types of culverts can be used based on where one wants to construct and the budget for the construction. Based on the shape the most common culvert types are pipe, arch and box culvert. The pipe culvert is cylindrical in shape and is the mostly used in small roads and streams. Arch Culverts are used when the drainage is broad, and it is not supposed to interfere with. The box culvert, on the other hand, is massive in size and used in highways and other construction across big streams.
The type of culvert too can be classified based on the material that they are made of. In this category there can me concrete, corrugated iron sheet and plastic culverts. The strength and durability of the different types of culverts differ.
In some cases, custom culverts can be developed on site if the existing culvert shapes do not meet a person needs.
What to consider when selecting the culvert for installation
Installing culverts requires caution to select the best culvert that will meet one’s needs. The size of the ridge or stream is very important, for small stream small diameter culverts can be used and the size increases with increase the size of the stream. One has to consider the place where the watermark is highest and take dimension of the depth of the water, with of the ridge and the length to be accurate is selecting the culvert. For smaller streams, plastic, corrugated iron sheets, and concrete culverts can be used.
The activities that will take place above the culvert is important in selecting the culvert type and material. If above the culvert will be used as a road for vehicles and other activities, Concrete or corrugated culverts are preferred but for paths and pavements plastic culverts can be used.
The maintenance of the culvert is very important when Culvert Installation is being considered. Need for maintenance will also determine the shape and design. Long and narrow culverts are challenging to clean and can easily be blocked by the soil of silt that is carried by water.
The ending of the culvert is imported as it enhances direction and flow of water through the culvert. The design of the culvert thus is important for culvert function.
