T130 hollow bar anchors

T130 hollow bar anchors are the large diameter anchor bars which can reduce surface subsidence, prevent collapse effectively, improve bending strength and control inclination. It has low noise and small vibration, so it is convenient for construction. It is mainly used for unstable ground conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations. For projects facing such ground conditions, T130 hollow bar anchors should be considered as the main productivity solution and designed for optimized installation, tailored to the project’s needs.

T130 hollow bar anchors are especially used in the unsteady geological conditions,such as sand, gravel, silt, clays and the soft to medium fractured rock formations. So the traditional construction problems will no longer be the problem.On the other hand, the flexible and simple installation process can obviously increase the efficiency of some temporary supporting projects.
