        when the urumqi airport surface renovation project department of jinghang airport conducted the road surface reconstruction process, technicians made bold trials in technical innovations and broke two technical difficulties: the 11-kv electric joint cutter adopted cutting dicks whose diameters were 80 cm. the cutting in-depth was between 20 and 22 cm. large-power trenchers were used to eliminate notch grooving. the trench was 8 cm in width and 20~25 cm in depth. the average speed of digging a trench was over 80 m/h, which basically solved the issues of common electric pick elimination, including high safety risks, uneven depth and high consumption of human labor.
