![]() ![]() You can use it from clearing and rubbing, removing topsoil – that’s full of moisture and organic material, to filling gravel and cleaning fill. In fact, the most common use of bulldozer is in road construction and road building. Road Construction – The large flat blade on the front is pretty helpful in spreading road fill material during construction of highways and pavements.It can knock a house over, saving the trouble of deconstructing one piece at a time. Because of its massive size and claw-like extension you can use it for small and large size demolition projects. Demolition Projects – It is a quite useful heavy machine for demolition projects.Here’re some applications and uses of bulldozers in construction and other industries: Construction Bulldozer parts and functionsīulldozers are heavy equipment used in United States for helping in digging, excavating, leveling, and pushing soil and debris at work site. ![]() Some bulldozers are available with modifications like rippers in the rear to help breakdown tough ground. A bulldozer blade goes along the front of the dozer that pushes material. The right size of bulldozer blade for your construction job depends upon the nature and requirement of work. The term bulldozer is given to this heavy equipment because of the blade attachment that goes along the front of the machine. Different types of bulldozer with varying sizes are available in the market.Īmong the most common types of heavy equipment used in United States bulldozer is quite common. The excavation definition outlined above only covers the most common processes in residential construction.Bulldozers or simply dozer is a machine that is mainly used for digging, pushing, excavating, and for leveling the different materials like soils, coarse aggregate for roads and removal of debris at work site. The excavation is larger than the final building and will have to be back-filled after the concrete walls are built. Excavation for basements is usually performed by a heavy equipment machine called an excavator or track loader. Basements can be completely below grade, or in the example of a daylight basement, it would be at ground level on one side and at surface level on one side. BasementĪ basement is the part of the building below ground level. This is also done utilizing a laser and a grade checker to keep the excavation level for the footings. This protects the home foundation from expansion and contraction (heaving) due to frost. These excavations are usually between 18 inches deep and several feet deep as shown in this video. These are always excavated to an elevation lower than the frost line. The excavator in the video below prepares a sub-surface area for installation of the house footings. Sometimes, this is the best and most effective method to use. The video clip below shows a contractor using a rock breaker attachment in the trench. This is because it cannot be done without the use of special heavy equipment. Rock excavation is highly challenging as compared to other types. Inspect trenches following a rainstorm.Inspect trenches at the start of each work period.Know where underground utilities are located.Keep surcharge loads at least 2 feet from trench edges.Keep heavy equipment away from trench edges.It also includes trenching for power, phone and cable. ![]() Trench excavation is typically used to bury utility lines, including water, sewer and gas services. It is a narrow underground trench that is between 4 inches and several feet wide. ![]() This type of excavation is where the length of the excavated area exceeds the depth. In the video below, the equipment operator on the skid-steer is cutting and filling the building pad. Prior to the cut and fill, one would usually clear the area of vegetation and strip and stockpile the topsoil off the building pad area. Most Common Types of Excavation in Residential Construction Cut and Fill Excavators are also known as diggers or sometimes trackhoes. An excavator has a bucket, boom and a cab mounted on a rotating platform that sits on tracks like a tank, or it has wheels. A dozer has tracks with a front blade and sometimes a ripper on the back. It is often the only machinery used on small to medium projects. A backhoe has both a rear-mounted digging bucket on a two-part hinged arm and a front shovel-bucket. Although other equipment can be used, digging typically involves a backhoe, loader, dozer or an excavator. Most excavation work is done by heavy machinery. ![]()
