　　Pre support small pipe tip shrinking machine, precision constant grouting small pipe tip shrinking 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.

　　Construction method of small conduit

　　The advanced small guide pipe adopts a seamless steel pipe with a length of 3.5m and is arranged within the range above the arch line of the tunnel. The circumferential spacing of the small guide pipe is 30cm, and the pipe body is arranged with drainage holes in a plum blossom shape with a diameter of 6-8mm and a spacing of 20cm to 30cm; The end of the small catheter is processed into a pointed tip, and the palm surface is drilled or directly inserted. The construction of small conduits should meet the following requirements: 1.1 The overlapping length of the front and rear rows of small conduits should not be less than 1.0m. 1.2 When the small conduits are arranged by drilling holes, the drilling depth should be greater than the length of the conduit. When using hammering or drilling machines to insert, the insertion length should not be less than 90% of the length of the conduit. 3 The grouting slurry ratio of the small conduits must be determined through experiments, and the grouting process is simple, easy to operate, safe, and environmentally friendly. During the grouting period of the small conduit, regular sampling and laboratory testing of groundwater should be carried out. If there is contamination, a pre protected small conduit shrinking machine should be used for precise and constant grouting. A small conduit shrinking machine should be used for forming small conduits

　　The small catheter tip machine ensures reliable operation of the small catheter tip machine. Automatic tracking circuit, automatic adjustment of load impedance matching, achieving constant power output, power factor of over 95%, wideband design, available for HZ power supply selection. Complete protection measures such as overcurrent, overvoltage, phase loss, undervoltage, and inverter failure ensure that the small tube tip machine does not damage any components in the event of a malfunction. Rich external control interfaces make it easy to achieve closed-loop adjustment of power supply, workpiece temperature. Advanced small conduits are generally used in conjunction with steel frames and are applied for advanced grouting and pre support of Class IV and V surrounding rock arches. The characteristics of the small conduit tip machine are based on objective conditions to develop practical and feasible construction and construction related measures; Select the name, specification, material, and technology of the grouting material, and propose the material quantity and essential auxiliary material quantity for pre support small pipe shrinking machine and precision constant grouting small pipe shrinking forming machine.
