Full threaded steel self drilling rock bolt / Hollow anchor bar / Anchor rods
The Self Drilling Anchor system is comprised of a hollow threaded anchor bar with a sacrificial drill bit that performs drilling, anchoring and grouting in a single operation. Widely used as an efficient anchoring means, in tunnel pre-support, slope, coast, mine, water conservancy projects, building foundation, roadbed reinforcement and geological diseases treatment such as landslip, crack, sink age. It`s irreplaceable in narrow construction environment. Hollow anchor bar is made of seamless tube with high strength.
Advantages and Characteristics as below:
1. No casings required, because anchor bars can be drilled into loose soils without needing casings to support the boreholes.
2. Fast drilling and installation, because drilling, installation and grouting are in a single operation.
3. Both rope threads and trapezoid threads are robust and ideal for rotary-percussive drilling and ensuring a high level of bondwith the borehole gout.
4. The hollow core not only serves for flushing during drilling, but also for grouting after drilling.
5. Continuous threads ensure the bars can be cut and coupled at any point, or extended.
6. Different anchor bits are available for different ground conditions.

Ni Buqing, head of North Asia and China in ABB's Low Voltage Products Division, stated: “As a large-scale public building, the Macao Science Museum has high requirements for the advanced, energy-saving, safety, and stability of building control systems. ABB Solutions is proud of its successful application at the Macau Science Museum, and ABB’s sophisticated i-bus® intelligent building control system adds a sense of science and technology to this new science and technology facility, giving young people the opportunity to access today’s most advanced intelligence. The control technology also embodies the concept of using science and technology to build a green world and lighten high quality of life."
Intelligent buildings can optimally design elements such as structure, equipment, service and management of buildings according to user needs, thereby creating an efficient, safe, comfortable and convenient environment. ABB in-depth study and study of the indoor and outdoor environment of the Macao Science Museum, combined with its features of a wide area, a large number of lighting loops, through the scientific measurement for its tailored application solutions.
In the project, the ABBi-bus® Intelligent Building Control System centrally controls over 100 lighting circuits in 14 permanent pavilions through a central visualisation host. The user can set parameters for the controlled area through a simple and easy-to-understand human-machine interface on the smart panel, and realize that the light is turned on or off automatically, or the manual control can be flexibly selected according to actual needs.
According to calculations, the use of the ABBi-bus® Intelligent Building Control System can help the Macao Science Museum Exhibition Center to save 15% of lighting power compared to the conventional system, while reducing the workload of management and maintenance personnel, enabling users to reduce management costs and Operating costs.
As the main representative of ABB intelligent building solutions, ABBi-bus® smart home control system has been successfully applied in the world for nearly 20 years. It is the world's first intelligent building control system that meets the international ISO/IEC14543-3 standard, and meets the European EN50090 standard, the Chinese national standard GB/Z20965 and other advanced standards. It can not only control the lighting equipment, but also can be widely used in air conditioning of new buildings. Office appliances, electric curtains, video equipment, integrated control. The ABBi-bus® Intelligent Building Control System participates in a number of landmark buildings around the world. In China, this product has been used in many public buildings and civil projects such as the Capital Airport T3 terminal, the National Stadium (Bird's Nest), the National Swimming Center (Water Cube), and the Beijing TV Center.
The Macao Science Museum is the first international standard science education facility invested and built by the government of the Macau Special Administrative Region. It covers an area of ​​62,000 square meters and includes three main parts: the exhibition center, the planetarium and the conference center. The museum invested 337 million patacas (or 276 million yuan in contracts) and was started in October 2006. It was completed at the end of 2009 and opened in January 2010.
ABB is a leader in power and automation technology in the world's top 500 companies. ABB is committed to helping power, utilities and industrial customers improve their performance while reducing their impact on the environment.
