　　The small pipe taper machine plays a crucial role in the construction industry. A small conduit is an indispensable step in construction, as it can effectively penetrate into the wall. The pointed end at the front is relatively easy to penetrate, and the small holes on the steel pipe wall are added to enhance the strength of the surrounding rock. The small tube taper machine has a fast taper speed, and the taper of a pipe can be completed within one minute.

　　Characteristics of the small tube shrinking machine:

　　1. Suitable for processing metal pipes of various materials and various shapes of pipes;

　　2. The components undergo strict quality inspection, with superior quality and standardized specifications;

　　3. This machine has both manual and automatic functions, and is equipped with an emergency stop device;

　　4. Shrinkage processing stroke of 120mm, processing item length of 4500mm;

　　5. Automatic delivery can be added, and the operator only needs to perform collection or cutting work;

　　6. Processing shapes: concave, convex, sectional, long flat, square, extended, inclined, V-shaped, open elbow, etc., depending on the workpiece, the mold shape can be changed. Subway 42 small pipe taper machine precision constant pipe taper forming machine usage method

　　Advanced small pipe grouting is a process of sealing the excavation face and the tunnel within a range of 3m-6m with sprayed concrete before tunnel excavation. Then, perforated small pipes are injected into the surrounding rock along the tunnel perimeter, and grout is injected into the surrounding rock through the small pipes to provide bonding. After the grout hardens, a reinforcement circle with a certain thickness is formed around the tunnel to protect the excavation operation. Advanced anchor rods and advanced small steel pipes are installed along the excavation contour line with slightly larger external insertion angles towards the front of the excavation face, forming a pre anchoring of the surrounding rock in front of the excavation face. Construction is carried out under the protection of the pre formed surrounding rock anchoring ring. The subway 42 small pipe taper machine and the precise constant pipe taper forming machine are used.
