　　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.

　　The design parameters of the advanced small conduit machine are a seamless steel pipe with a length of 4~7m and a diameter of 6~8mm. The pipe wall is drilled in a staggered plum blossom shape every 20cm, and the diameter of the hole is 6~8mm. The diameter of the hole when drilling with a pneumatic drill is 2cm larger than the pipe diameter. The top of the small conduit is a pointed cone shape to facilitate the conduit to be inserted into the rock wall borehole. After the small conduit is inserted into the rock mass, the tail end is left with 5-10cm, and a short steel pipe with a check valve (such as a water switch) is welded. Generally arranged within a 120 ° range of the arch top, with a circumferential spacing of 30-50cm and an external insertion angle of 10-30 °, the subway small pipe taper machine and the precision constant steel pipe taper forming machine are priced at the factory.

　　The weight ratio of grouting material configured is: water: filling mortar=100, plus 0.08% micro agent; Cement should be made of Portland cement; The grouting material requires continuous mixing, and the dosage of each material should be strictly monitored during mixing to ensure grouting; Step grouting: Start the grouting machine and observe the second circular hole, third circular hole, and fourth circular hole in sequence. At the same time, make an exhaust hole to determine whether to inject concrete slurry. When the concrete slurry in other observation holes reaches the same density, immediately end the grouting and seal the circular hole; When the pressure reaches 1.0 MPa and the hole opening has not yet been filled with concrete, the next grouting hole should be replaced and grouting should be carried out again until the second, third, and fourth circular holes in the middle and the observation hole on the end of the template 12 are filled with concrete for 3-5 seconds, and grouting should be stopped; After the grouting process is completed, remove the concrete grouting conveying hose from the outlet pipe of the grouting machine and the end pipe of the variable diameter pipe joint. The subway small pipe taper machine is a precision steel pipe taper forming machine with factory price.
