Bolting device 25 hollow grouting anchor Supplying

Bolting device 25 hollow grouting anchor factory direct 18603793535 Thai Technology Co., Ltd. in Luoyang River hollow bolt manufacturers produce processing a variety of types of hollow bolt grouting anchor steel pipe shed with flower tubes are raw materials thick-walled seamless steel pipe for high-quality workmanship quality assurance Welcome to the new and old customers to inquire www.jiangtaikeji.com hollow grouting anchor bolt is removed from the self-drilling drilling function evolved from the full thread of the hollow bolt body , together with the anchor head, plate, nut, only the pulp plug and so on. Features 1. hollow hollow grouting anchor design, the bolt to achieve a grouting pipe function, avoiding the traditional construction process when the mortar grouting pipe pull out due to the loss. 2. The full grouting, pressure grouting can achieve, improve project quality. 3. As the role of the various parts of the center rod is very good, the mortar can be the full length of bolt body wrap, to avoid the risk of corrosion, achieve long-term support purposes. 4. Easy installation, no on-site processing thread, you can easily install plate and nut. 5. The combination of supporting special injection pump and bolt grouting technology, is the only complete solution to the traditional problems of anchorage support anchorage system. Hollow grouting anchor Scope 1, radial reinforcement: hollow bolt instead of the traditional mortar anchor for radial reinforcement, construction technology can solve the traditional mortar anchor grouting process is not full, and many can not achieve pressure grouting defects, ensure project quality. 2, Slope: hollow bolt reinforcement unstable slope, not only the process is simple, low cost, and convenient construction, the effect is significant. 3, excavation: excavation of the building reinforced hollow bolt, not only a simple process, but also to achieve pressure grouting, improved pit rock conditions. Hollow grouting anchor Technical Data General Standard provides the following table: Size JT22 JT25 JT28 JT32 outer diameter (mm) 22 25 28 32 tensile strength (KN) ≥150-180 ≥150-180 ≥180-220 ≥220-250 Note Pulp Aperture (mm) ≥12 ≥15 ≥17 ≥22 hole diameter (mm) 42 42 42 51 Thread direction left (right-handed customizable) Standard length (m) 3 3.5 4 4.5 length error ± 2.5% Note 1, hollow Bolt and mechanical properties according to user requirements; 2, the length of the bolt can be processed according to customer requirements; 3, the screw direction according to customer processing requirements; 4, plate, nut, only the pulp plug, anchor head, drill, connected sets available upon request
