<a href ="http://www.hollowbar.org/product/hollow-bar-anchor/"><b> Hollow bar anchor </b></a> is widely used in foundation pit support engineering recent years. It can combine drilling, grouting and anchoring together, time-saving and high-efficient. In addition, during the construction, there is no shake, no noise and no deformation phenomenon, it has little influence for surrounding environment. After its installation, the intensity of wall is strong, stiffness is big and supporting stability is good. If <a href ="http://www.hollowbar.org/"><b> hollow bar  </b></a>is shorter than designed depth, coupling is used to connect another one and lengthen it. Drill bit is made of materials with strong penetrating power, which can drill rock with different hardness. Grouting can keep certain pressure and be benefit for slurry filling gaps among surrounding rock. Nut can concentrate and transfer stress to its plate. Hollow bar for hydroelectric can also used for supporting slope, reinforcing surrounding terrain and avoiding collapse or other geological disasters.
