　　Hydraulic small pipe punching machine, Jingheng tunnel support small pipe punching machine

　　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.

　　Wide range of functions. The main operating system of the CNC fully automatic punching and cutting machine with high sales volume is completely independently developed by the developer and can accept customer orders. Therefore, its system can add corresponding operational functions based on the data and different needs provided by customers. At present, CNC fully automatic punching and cutting machines can achieve various tasks such as punching arc ports and pressing gun tips on the same machine, which greatly saves the procurement cost of mechanical operation equipment for enterprises. Hydraulic small pipe punching machine Jingheng tunnel support small pipe punching machine.

　　The punching machine generally consists of the following two parts: the general measurement of grouting support for small conduits is as follows: the diameter of the steel pipe is 30-50mm, the length of the steel pipe is 3-5m, the spacing between the grouting holes drilled on the steel pipe is 100-150mm, the spacing between the steel pipes along the arch is 300-500mm, and the angle of the steel pipe along the arch is 5-15 °. The small conduit is a load-bearing member, so there should be a certain overlap length between the two rows of small conduits in the longitudinal direction, and the overlap length of the steel pipe along the longitudinal direction is generally not less than 1m. The advanced support of the pipe shed is a new technology developed in recent years for excavation in weak surrounding rock. The pipe shed method has long been used as an auxiliary construction method, playing an important role in crossing fractured zones, loose zones, weak strata, and water and sand layers in soft rock construction. Due to the pre embedded advanced pipe shed as the top plate and side wall support, it lays the foundation for subsequent excavation, and is considered an effective and reasonable construction method to solve the problem of collapse during construction due to its fast construction, high efficiency, and short construction period. ）Thirdly, the tight supply of coal has led to some power plants' generator units being restricted or shut down, affecting their normal electricity consumption. At present, most regions in China mainly rely on thermal power generation, using coal as fuel, hydraulic small pipe punching machine, and Jingheng tunnel support small pipe punching machine.
