　　Punching machines have been widely used in tunnel construction. The punching machine can set 200 holes on one pipe, and the machine is matched with a servo motor. The hole spacing error is within ± 0.3mm, and the punching speed is fast, which greatly improves the manual cutting speed compared to before. The circular holes are also relatively neat and beautiful.

　　The type of equipment for the small pipe punching machine should be selected based on the nature of the process to be completed, batch size, geometric dimensions of the workpiece, and accuracy level. From a perspective, generally open press machines are not as good as closed press machines; Mechanical presses are not as good as hydraulic presses; A free forging hammer is not as good as a forging hammer. Of course, it also depends on the actual situation on site and cannot be generalized. To prevent the small tube punching machine from hitting eccentricity, pay attention to the following points:

　　1. Regularly adjust the clearance between the press guide rail, slider, and the guide column and guide sleeve of the mold to prevent eccentric strikes.

　　2. In addition to adjusting the gap between the upper and lower blades, it is also important to use a good pressure plate for the small pipe punching machine tool to avoid tool edge cracking caused by rebound or misalignment during the cutting process.

　　3. When punching, try to use positioning devices such as positioning panels, punching positioning cover plates, etc., to reduce the possibility of eccentric punching. Rock reinforcement small pipe punching machine, precision and advanced small pipe punching machine manufacturer.

　　The small conduit bears the pressure of the formation during tunnel excavation. To ensure grouting quality and prevent leakage, a sealing hole needs to be set at the tail of the small conduit.

　　The grouting method should be selected according to the soil conditions for grouting construction: infiltration grouting method should be used in sand and gravel formations; Squeezing and infiltration grouting methods should be used in sand layers; Splitting or electric silicification grouting method should be used in clay layers; It is advisable to use high-pressure jet grouting method in the soft soil layer of silt.

　　The grouting material should have good injectability, and after consolidation, it should have a certain strength, impermeability, stability, durability, and small shrinkage. The grout should be non-toxic, and the grouting process should be simple, convenient, and safe. The selection and proportioning of grouting materials should be determined through experiments based on engineering conditions.

　　During the grouting construction period, it is necessary to monitor whether the groundwater is contaminated, and prevent the grouting slurry from overflowing the ground or exceeding the grouting range. The manufacturer of the precise and advanced small pipe punching machine for rock reinforcement should also be taken into account.
