Achieving a large restraining force by inserting indented PC steel wire.
The "SP Soil Nail - SR Type" is based on the conventional "SP Soil Nail" but further improves the tensile strength of the core material. It features a unique design where PC steel wire, which has been processed with indentations to enhance adhesion, is inserted after the main wire, making it an economically superior Strand Reinforce (SR) type of simple double-tube high-strength rock bolt method that can also be proposed for partial areas of permanent anchors. 【Features】 ○ Significantly increased strength providing anchor-like restraining force ○ Insertion of PC steel wire after bolt installation For more details, please contact us or download the catalog.

basic information
【Features】 ○ By inserting indented PC steel wire into the hollow bolt, the strength of the core material is significantly increased. ○ Capable of providing restraining force that could not be achieved with conventional reinforcement methods. ○ Active "two-directional pressure injection" through a partial double-tube method improves the extreme surrounding frictional force with the surrounding ground. ○ Immediately after injection, "indented PC steel wire is inserted into the inner hole of the bolt," improving the tensile strength of the core material. ○ Construction is possible up to about 7m with a general-purpose single-tube drilling machine, and up to about 9m with a hydraulic machine that has high rotational power. ● For more details, please contact us or download the catalog.
