随着经济的发展,国家公路建设日新月异。在公路建设中,预应力锚索加混凝土格栅和锚杆挂网喷射混凝土技术要求高,采用了先进施工方法和手段。施工中关键要控制好工序质量,要保证预应力锚索基岩锚固段的长度,建立有效的变形观测手段和信息传递责任制度,杜绝安全事故的发生,保证边坡支护质量安全可靠。
With the development of economy, the development of national highway is changing rapidly. In highway construction, prestressed anchor plus concrete grilles and bolt-net shotcrete high technical requirements, using advanced construction methods and means. The key to the construction process is to control the quality of the process. To ensure the length of anchor section of prestressed anchor bedrock, effective deformation observation means and information transfer responsibility system should be established to eliminate the occurrence of safety accident and ensure the quality of slope support is safe and reliable.
