喷锚支护是隧洞工程常用的支护方法,喷锚支护又分为普通喷锚支护和预应力喷锚支护。预应力锚杆喷锚支护施工技术要求高,工艺复杂,施工周期长,特别是在洞内施工,空间狭窄,施工干扰大。优化设计参数,采用合理的施工方法,可保证工程工期及工程的经济性。
Spray anchor support is commonly used in tunnel engineering support methods, spray anchor support is divided into ordinary spray anchor support and prestressed anchor spray support. Prestressed bolt shotcrete anchor support construction of high technical requirements, complex technology, construction period is long, especially in the construction of the cave, space is narrow, the construction of large interference. Optimize design parameters and adopt reasonable construction methods to ensure the project duration and the economy of the project.
