Self advancing anchor rod has the function of integrating drilling, injection, and anchoring, and is an advanced anchor solid The system solves the problem of collapse holes during the construction of large pipe sheds and can ensure grouting under complex geological conditions Slurry effect. In terms of bending resistance, shear strength, and surface adhesion, it is significantly better than those with the same cross-section Standard mortar anchor rods can be cut, connected, prestressed and load released at will, and can be used for The use of grouting pipes requires no special requirements for machinery, equipment, and materials. The process is simple and has Great application value.

The self advancing anchor rod consists of a rod body (fully threaded rod in the air), a connecting sleeve, a disposable drill bit Arched cushion plate and nut composition. Rubber sealing slurry plugs can be added to the tail of the anchor rod during grouting. When drilling, The tail of the anchor rod is connected by a connecting sleeve and equipped with a drill tail (the shape of the drill tail is the same as that of a regular drill rod).

 

Self advancing anchor rods have the following performance and characteristics
(1) Equipped with a drill bit, it can self drill into the self-propelled anchor rod, which has two functions: drill rod and anchor rod,
Canceling the process of returning drill rods and inserting anchor rods can avoid rework caused by hole collapse.
(2) The anchor rod body can be extended and has multiple specifications, making it convenient to use
Prefabricated self advancing anchor rods are available in standard lengths of 2m, 3m, 4m, and 6m, with specifications of R25N, R32L, R32N, R32S, R38N, R51L, R51N, T40,T76L, T76N
T76S type, extended with connecting sleeve (the outer surface of the rod is an international standard waveform thread), during drilling
Drill into one segment after another; Firstly, it is easy to disassemble and assemble, and secondly, it has strong shear resistance.
