In traditional construction, carpenters often cut rafters on-site using hand tools, but today pre-cut and pre-engineered rafters are commonly used for efficiency and cost-effectiveness. Fig1: Rafter Courtesy: housing.com A roof has many different parts that hold it together. One of these ...
(3) The pipeline transportation construction period is short and the cost is low. A large number of practices in the construction of transportation systems at home and abroad have proved that the construction period of pipeline transportation systems is generally more than 1/3 shorter than the con...
Both temporary and permanent excavations are reinforced using shotcrete. It can be used to stabilize an excavation for an underground parking facility or high-rise buildings during construction, in conjunction with lagging and other types of earth anchors. Shotcrete has a wide range of uses on curve...
