A great many projects show that traditional mortar anchor bolt can not fill fissures by prestressing injection in various unconsolidable rock conditions to improve surrounding rock mass and increase the strength and stability of the earth mass.

Self drilling hollow bar has been widely used for underground engineering construction support project and have solved the problems of underground side wall and arch section,as well as silp casing by pressure and anchoring support of arch anchor bolt with certain elevation.Guarantee the safty and quality of construction.

Though small in diameter,hollow bar micropiles are incredibly strong. Designed to support loads in excess of 200 tons, they stabilize slopes, foundations, and structures at both 

shallow and deep depths. Because they can be installed in almost any subsurface, micropiles are one of the most popular and cost-effective support solutions. Installation is simple and 

rarely disrupts facility operations.

Sinorock mainly produces hollow bar anchor for mining, construction and related industries. 

Since 2011, Sinorock has been striving to provide customers with fast, stable and economical solutions for rock drilling, and effectively help them reduce rock drilling cost. Now 

Sinorock has been a specialized manufacturer of rock drilling tools with integration of self drilling hollow bolt, production, related products supply and solution consultancy.
