Structural aspects:
The structure of Hollow Rock Support Anchor Bolt is more complex, which is composed of shell, bolt core barrel, anchor, anchor head, torsional shear controller, etc. The prestressed adjuster can adjust the bolt according to the demand to meet the construction requirements.
The structure of ordinary Hollow Rock Support Anchor Bolt is relatively simple, mainly composed of shell, anchor head and bolt core tube, etc. Its design mainly focuses on the basic function of bolt, that is, providing support and fixing.
Materials:
The material used in the hollow anchor bolt has strong corrosion resistance and fatigue properties, and the high-strength steel can be adjusted according to the needs to achieve the expected prestressed strength requirements. This material can adapt to more complex engineering environments and ensure the durability of the bolt.
The bolt core tube of ordinary Hollow Rock Support Anchor Bolt can be made of ordinary steel or steel with weak corrosion resistance, and its material selection pays more attention to cost effectiveness and applicability.
Features and Benefits:
A significant advantage of Hollow Rock Support Anchor Bolt is its grouting function. Due to its hollow design, it can be used as a grouting pipe to inject grout into the rock mass that needs to be reinforced. This grouting method can effectively fill the void in the rock mass and improve the overall strength of the rock mass. In addition, the Hollow Rock Support Anchor Bolt can also reduce the loss of mortar caused by the withdrawal of the traditional grouting pipe, ensure the fullness of the grouting, and further improve the quality of the project.
The prestressed Hollow Rock Support Anchor Bolt is adjusted by prestressed adjuster to make the bolt produce a certain preload when it is installed. This kind of preload force can exert pressure on surrounding rock actively and improve the resistance to damage of surrounding rock. At the same time, the grout of prestressed Hollow Rock Support Anchor Bolt can quickly penetrate into the hole and the surrounding rock mass cracks under high grouting pressure, so as to ensure full filling and compaction of the slurry to the maximum extent, and achieve better anchoring support effect.
Although the ordinary bolt also has certain supporting and fixing functions, its function is relatively simple, and it can not provide advanced functions such as grouting and prestress adjustment.
In general, Hollow Rock Support Anchor Bolt is superior to ordinary bolt in structure, material and function, especially suitable for complex engineering environment requiring grouting and prestress regulation. However, because of its simple and economical characteristics, ordinary bolt still has a wide range of applications in some occasions where support requirements are not high.
