  The hollow bolt design is flexible, purposeful and adaptable. According to different roadheader models, geological standards and coal road cross section regulations, the design scheme can be double-arm or arm hollow grouting bolt method;

Hollow bolt

  What are the application advantages of Xinben recommended hollow bolts?

 

  The hollow grouting anchor has a relatively simple structure, and it is very easy to check and repair common faults. The hollow design scheme completes the function of grouting; the grouting is round and can complete the working pressure grouting. The centering of the rod body is good, and the cement mortar can encapsulate the total length of the anchor cable body, preventing the probability of rust, and achieving the purpose of long-term bolt support. The installation is convenient, without the need to produce and process external threads on the spot, you can easily install the pads and nuts;

Hollow grouting anchor

  Hollow bolt manufacturers integrate into the coal roadway to cover a wide cross section, and consider the support of most roof and side anchor cables in different coal roadways and general technical specifications. Compared with continuous coal mining machines and tunneling anchors, The height-to-width ratio and total width specifications of coal roadways are relatively small;

 

  Reduce the labor efficiency of employees, and improve the anchoring office environment-in a fully mechanized coal roadway, when the roadheader cuts the coal, after the coal is discharged, the roadheader is pulled back 3-5m, and then a single anchoring rig is moved to the work surface to carry out Drilling work, after the drilling work is carried out, the single anchor drilling rig needs to be removed from the work surface. This process is coordinated with the hollow anchor rod, which can prevent employees from constantly moving a single anchoring rig. Drilling can be carried out without manpower moving the anchoring rig, and simply control the valve handle;

 Hollow bolt manufacturers

  The volume of the tunnel boring machine is relatively small after the hollow grouting bolt is modified, which can show a relatively fat working natural environment for the mine staff, which is convenient for the production and manufacture of the mine staff, and is also convenient for natural ventilation of the excavating head;

 

  Hollow grouting bolts have little harm to the characteristics of cantilever roadheaders, including the convenience of actual operation by the roadheader driver, the location of the center of gravity and the change of the specific pressure of the grounding device after the hollow grouting bolt is installed, and the difficulty of maintenance after supporting facilities Coefficients, etc.;

The installation is convenient, without the need for on-site production and processing of external threads, the pads and nuts can be easily installed.

 

  Incorporating into the coal roadway with a wide cross-section coverage, it is possible to consider the support of most of the top and side anchor cables in different coal roadways and general technical specifications. Compared with the continuous coal mining machine and the digging anchor machine, the coal roadway height is integrated The aspect ratio and total width specifications are relatively small;
