　　The advantage of using the product: Because of the grouting pipe each segment between 1m-4m, each section of which is 33cm long, inner diameter of 40 mm, an outer diameter of 56mm, each section is screwed together, and the two outer ends of the spiral cold forming linker, grouting pipe segments with an internal thread, not only increase the strength of the connection, but also ensure concentricity after connection by ensuring the verticality of the grouting pipe, at the same time, because each segment grouting tube length is large, reducing the number of connections, easy construction operations, improve the construction schedule, with each segment using grouting pipe extruded into the plug, the inner diameter of the grouting pipe to ensure consistency in grouting, grouting up and down pull easily avoid the back to avoid plasma phenomena in the grouting pipe; therefore, improve the construction quality.
