Construction Technology of Bolt Ball Steel Grid Structure for Underground Factory Building
In order to maintain a dry,clean,and comfortable environment for the later operation of the factory building,as well as to meet the needs of permanent ventilation,lighting facilities,and other arrangements,the suspended ceiling of the underground factory building in hydropower projects is generally made of concrete or steel structure.The bolted ball steel grid suspended ceiling is widely used in underground power plants of current hydropower projects due to its advantages of simple structure,strong bearing capacity,easy construction,and fast construction speed.The underground powerhouse of TB hydropower station adopts bolted steel grid suspended ceiling,which shortens the construction period and accelerates the construction progress.
