Drilling grouting method is widely used 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 on surrounding environment. After its installation, the intensity of wall is strong, stiffness is big and supporting stability is good.Anchor bolt support is a useful method.
Anchor bolt support is a common form in bridge projects, it is widely used in pier foundation and has advantages of fast-speed, small land occupation, little interference and big carrying capacity, etc.
During the construction of anchor bolt, there are measuring work, mechanical operation, drilling and grouting work. With wide variety and high technology, it’s easy to appear problems, such as big deviation, many sediment, up-floating of steel cage and some quality problems.
The remedial measures are difficult and complex, so several tips need to be pay attention in advance.
To reach the goal of construction quality, every index during construction should meet design requirement and acceptance level, including
anchor bolt’s location, length, diameter, intensity of concrete, sediment, verticality, material quality and ultimate load, etc.
To produce high quality anchor bolt system, the raw and processed material is one of the most important parts.Sinorock has a series of strict inspections for their raw materials when purchasing into their factory.Sinorock focuses on every detail to assure that their products are high quality anchor bolt systems.

Self drilling anchor bolt is a very good choice for engineering. Combining drilling, grouting and anchoring together, it’s reliable, efficient and convenient. Sinorock can produce R25, R32, R38, R51, R63, T30, T40, T52, T73, T76, 103, T111, T127 and T130 sizes and customized products to meet all the demands of self drilling anchor bolts.
