(Presseportal openBroadcast) - Hollow bars has two performances: drilling and grouting. It features a hollow bore for flushing, or simultaneous drilling and grouting. It

can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer where it is so difficult to create a hole in

complex formation. The unconsolidated ground conditions favor the self drilling anchor bolt technique for fast and simple method of

installed compared to the traditional method, which was confirmed by the application in Vertical Shaft at Left Bank of Xiluodu Hydropower

Station.



This is a demonstration of hollow bar installation.A new motorway is currently under construction. Sinorock supplied the complete range of

important ground control products for tunnel driving. This also included Type R32 and R38 �Hollow Bar Rock Bolts including accessories as

well as grout pumps. The Sinorock Drill Hollow Bar System proved itself by fulfilling the following technical characteristics in this

project:



1 Simultaneous drilling and grouting ensures an optimum bond between the hollow bar tendon and the unconsolidated rock or ground

2 The construction soil is improved by the infiltration of the grout into the surrounding unconsolidated soil

3 Uniform distribution of the grout along the complete installation length

The Sinorock hollow bar system has been utilized in countless soil nailing, shoring, and tieback applications. Please see below for a sample of our projects.

The Sinorock hollow bar system consists of fully threaded steel bars, couplers, a nut and various drill bits - which allows for the system to be drilled through various soil and ground conditions.
