(Presseportal openBroadcast) - With the increase of transportation, energy and other infrastructure constructions, the amount of self drilling hollow bar is increasing day by day in tunneling projects as a reliable and effective anchorage technology and has showed broad prospects for development and considerable market prospects. Self drilling hollow bar can fully anchor the full-length hollow bar and immediately provide support resistance to prevent looseness or deformation of surrounding rock after excavation, which avoids or delays the occurrence of landslides and other diseases during the construction and operation. After anchoring, the hollow bar will be around with sufficient and uniform protective layer of cement.

It will greatly enhance the durability of self drilling hollow bar and have a long-term recessive benefit hollow bar anchors tested satisfy the design requirement, achieve the purpose of fast speed and high quality and meanwhile get the following conclusions:①Hollow bar has advantage over mortar bolt in the reinforcement of tunnel lining and can greatly accelerate the construction speed and shorten the construction time on the premise of ensuring the quality especially for the urgent period. ② Hollow bar is a new structure and advanced technology with reliable quality and good durability. It can be largely applied to the temporary and permanent support of the new or reinforced hydraulic engineering and will be one of the development directions in the hydraulic engineering field.
