Bulldozer – Dam constructions
Dams are barriers, usually constructed across rivers to hold back and contain water in a lake or reservoir and are usually built using concrete, or natural materials such as earth and rock. Dam construction is often complex and requires a wide range of professionals and machinery. Bulldozers are used intensively for material pushing land levelling along with Excavators and Rollers.
Dam are constructed for one or more of the following purposes:
• Storage of water for urban supply
• storage of water for farm irrigation
• flood mitigation
Types of Dams
The first three can be sub grouped as embankment dams whilst there are also several different types of concrete dams:
• Embankment – earth – earth and rock – rock
• concrete – solid gravity – concrete arch – arch-gravity – hollow gravity.
The word “bulldozer” is sometimes used accurately for other similar construction vehicles such as a large front loader.
