　　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 processing range of advanced small conduits is generally only about 6 meters. The small conduit is a steel pipe with a wall thickness of 5mm and a diameter of 42mm. It is a method of consolidating the relatively fragmented surrounding rock in front of the palm face through small conduit slurry, so that the surrounding rock forms a whole before proceeding to the next step of work. The pipe shed is used when the geological conditions at the entrance of the tunnel are very poor (such as sandy soil, severely broken rocks, loess, etc.), with a general length of about 20-30 meters. The pipe shed is a steel pipe with a wall thickness of 3.5mm and a diameter of generally 108mm. Of course, when the geological conditions inside the tunnel are very poor, the pipe shed can also be used (such as when encountering roof collapse in the tunnel, resulting in a large length along the tunnel axis and a large amount of discharge). The tunnel grouting small pipe shrinking machine is a precision constant grouting small pipe shrinking machine.

　　It can be done by using a lead hole or direct insertion method:

　　Drill a hole with an electric drill, with a diameter 10-20mm larger than the diameter of the small conduit, and the depth of the hole depends on the length of the conduit.

　　If it is difficult to insert the catheter, a drill with a jacking function can be used to push the sleeve in.

　　Use a hair dryer to blow out any debris from the hole. jgfhakjfkla

　　Wrap cotton yarn around the tail of the 4 small conduits to ensure that they are tightly attached to the borehole, and use cotton yarn to seal the gap tightly.

　　After the installation of the 5 small conduits, a certain area around them must be sealed with sprayed concrete. The spraying thickness is controlled within 5-8cm for tunnel grouting small pipe shrinking machine and precision constant grouting small pipe shrinking forming machine.
