  Inventory of the nine advantages of hollow grouting bolts

  1. Hollow grouting anchor is flexible in design, pertinent and adaptable. According to different roadheader models, geological conditions and roadway section requirements, it can be designed as a single-arm or double-arm hollow grouting bolt form;

2. The hollow grouting bolt structure is relatively simple, and it is easy to check and repair faults. The hollow design realizes the function of grouting; the grouting is full and pressure grouting can be realized. The centering of the rod body is good, and the mortar can wrap the full length of the anchor rod body to avoid the possibility of corrosion and achieve the purpose of long-term support. The installation is convenient, and the backing plate and nut can be easily installed without the need for on-site processing of threads.

3. It can adapt to a wide range of roadway sections, and can meet most of the top bolts and side bolts required by different shapes of roadways and general regulations. Compared with continuous coal mining machines and digging anchors, it is relatively suitable for roadway height and width dimensions. Smaller;

4. Reduce the labor intensity of workers, and improve the working environment of anchor protection-in the fully mechanized roadway, when the roadheader cuts the coal, after the coal is discharged, the roadheader is withdrawn by 3-5m, and then the single bolt drill is manually Move to the working surface for drilling operations. After the drilling operations are completed, the single anchor bolt drill must be removed from the working surface. This process is carried out with the hollow bolt, which can avoid the workers repeatedly moving the single bolt drill. Drilling does not need to manually move the bolt drill. It can be completed by simply manipulating the valve handle;

5. Installing the hollow grouting anchor on the roadheader The volume behind the rod is relatively small, which can provide a relatively loose working environment for the underground workers, facilitate the production of the underground workers, and also facilitate the ventilation of the tunneling head;

  6. The hollow grouting bolt has little effect on the performance of the cantilever roadheader, including the convenience of the driver of the roadheader , the position of the center of gravity and the change of the ground pressure after the hollow grouting bolt is installed , and the difficulty of maintenance after matching;
