在地下工程中采用喷锚作为支护,这在我国煤炭、冶金、水利、铁道等部门已广泛应用,无论作为临时支护、初期支护,甚至永久支护都显示出了它的优越性和生命力,这是地下工程围岩支护技术上的一个重大改革,国家已在全国推广应用该项新技术。近年来由于新奥法在我国铁路隧道工程中得到迅速的推广,以及为节约木材而采用它作为临时支护,致使更扩大了应用。当前在地下工程中扩大应用喷锚支护这一新技术已成为科研、设计、施工等
Spray anchor is used as support in underground engineering, which has been widely used in China’s coal, metallurgy, water conservancy, railway and other departments. It shows its superiority both in terms of temporary support, initial support and even permanent support Vitality, which is a major reform of underground engineering support technology, the country has been in the country to promote the use of the new technology. In recent years, due to the rapid promotion of the new Austrian law in China’s railway tunneling project and its adoption as a temporary support for saving timber, the application has been further expanded. Currently expanding the application of underground engineering Spray anchor support this new technology has become scientific research, design, construction, etc.
