China's first self-developed high-end equipment for the construction of tunnels, the "modular door type multi-functional rock drilling rig", completes the main body of the structural parts. After the installation of the hydraulic system, control system and water circulation system, it will be first invested in the Menghua Railway Xi'an. Ling two-way 36-kilometer tunnel construction.
The modular gantry multi-purpose rock drilling rig developed by China Railway Science and Technology Group is mainly for the construction of full-section (or positive step) drilling, charging, anchoring and vertical steel pipe arch of I-III surrounding rock tunnel. It is a new type of full-hydraulic rock drilling rig with crawler track, multi-drilling arm and multi-function. It adapts to the current environment where the labor cost of tunnel construction has risen sharply and the safety requirements of tunnel construction are increasingly enhanced. It is a Chinese intellectual with completely independent intellectual property rights. "Build.
It is understood that the current domestic tunnel construction has been partially mechanized, but the excavation and standing arches are labor intensive or semi-mechanized, and the safety hazards are extremely high. The development of modular door type multi-functional rock drilling rig will greatly improve the current situation of too many working faces in tunnel excavation, high labor intensity and high risk, fill the gap in the field of domestic tunnel construction equipment, and accelerate the construction of tunnel construction in China. Mechanization, breaking the monopoly of foreign companies in the field of tunnel construction equipment, and enhancing the competitiveness of Chinese construction enterprises in the "One Belt, One Road" international market competition.
Concerned about surprises
Ceramic Pressure Sensor have the characteristics of high quality, high stability, small size, low weight, compact structure, low cost and volume-production. It is widely used to measure pressure such as occasion of compressor, Auto, air-condition etc. The product is made of stainless steel and well-known brand sensor. The special transmitter converting circuit can adjust the zero value and the full range expediently. It also has the intrinsically safe certificate, the explosion-proof certificate and the CE certificate.
