　　Operating procedures for CNC steel pipe taper machine and precision constant steel pipe taper forming machine

　　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.

　　Advanced small pipe grouting can change the condition and properties of the surrounding rock. After injecting the slurry into weak, loose formations or fractured rock fractures containing water, it can tightly and solidify with them. The slurry is used for filling, splitting, etc., to replace the water and air between soil particles and rock fissures, occupying their positions. After a certain period of time, it solidifies and binds the original loose soil particles or fissures into a whole, forming a new structure, high strength, and good waterproof performance of the consolidated body, which greatly reduces the loose and broken state of the surrounding rock. The determination of various parameters for the construction of advanced small conduits should be based on the geological conditions of the surrounding rock boundary, the condition of the surrounding rock, the form of the support structure, and the cross-sectional size. Generally, advanced small conduit construction is set within a 120 degree range along the excavation contour line. In general, the length of the small conduit is L=the height of the upper step+2m. The diameter of the small conduit is 38-50mm. The front section of the small conduit is made into a conical shape about 10cm long, and a steel reinforcement hoop with a diameter of 6-8mm is welded at the tail end. The external insertion angle is generally controlled between 10 degrees and 15 degrees. The grouting pressure is controlled at around 2MP according to the operating procedures of the CNC steel pipe shrinking machine and the precision constant steel pipe shrinking forming machine.

　　Performance characteristics of steel arches:

　　(1) The overall stiffness of steel arches is relatively high, which can provide significant early support strength; Steel arch frames can bear loads earlier than grid steel frames.

　　(2) Steel arches can be well combined with anchor rods, steel mesh, and concrete to form a joint support, enhancing the effectiveness of support and stress conditions. Especially with a grille steel frame structure.

　　(3) The grille steel frame is processed and manufactured on site, and the technical difficulty and requirements are not high; Good adaptability to cross-sectional changes.

　　(4) The installation and erection of steel arches are convenient, and the operating procedures for CNC steel pipe taper machine and precision constant steel pipe taper forming machine are as follows.
