what is hollow rock bolt?
Tunnel and Underground ProjectIn tunneling and underground projects, self-drilling hollow rock bolts play a crucial role in initial support and stabilization. These rock bolts provide high-pressure grouting to fortify soil or rock masses, ensuring surface stability and structural integrity within tunnels.
Products feature
1, easy installation, to ensure that the prestress application can be carried out in time.
2, active tension, prestress up to 50KN, and can achieve appropriate overtension.
3, using conventional tools, a single person can achieve the tensioning operation.
4, through the hollow rod body to achieve high pressure grouting, improve the surrounding rock.
5. Control the whole process from production to installation to ensure quality.
Products announcements
1. Grouting workers must bring protective tools.
2, carefully check the machinery and equipment and lines? Avoid electric leakage injury.
3, the mechanical driver in strict accordance with the operation procedures.
4, grouting workers and grouting pump drivers must be coordinated.
5, the grouting must first close the valve, and then pay attention to the slurry.
6, grouting mouth is not allowed to people
Products Application
Hollow grout rock bolt is a kind of reinforced concrete support material, with strong compressive, tensile and deformation capacity, so it is widely used in the following aspects:
1. Tunnel engineering: In tunnel construction, hollow bolt is used for strengthening and supporting the strata, which can effectively prevent ground collapse and collapse.
2. Mining engineering: Hollow bolt can prevent the occurrence of rock collapse, ground settlement, ground cracks and other phenomena, and improve the safety of mines.
3. Hydraulic engineering: Hollow bolt is used for dam reinforcement and support, which can improve the stability of the dam.
Products Advantage
Compared with the traditional bolt, the hollow bolt has the following advantages:
1. Strong carrying capacity: hollow anchor adopts hollow structure, which can reduce material consumption while ensuring strength, thus improving the carrying capacity.
2. Good seismic performance: hollow bolt has strong deformation ability, which can play a good protective role in the occurrence of natural disasters such as earthquakes and reduce losses.
3. Convenient construction: Compared with the traditional anchor bolt, the construction process is simpler, faster and reduces the construction cost
