Successive victories in underground construction, Zoomlion's double-wheel milling of Nanjing subway construction
October 10, 2022
Recently，On the construction site of Nanjing Metro Line 6，An aggressive Aurora green“Mechanical behemoth”Successfully complete the scheduled task，It is the first double-wheel slot Milling Machine of Zoomlion.ZC40。After 4 months of 24 hours of uninterrupted operation，ZCParticipate in the completion of diaphragm wall construction on schedule and with good quality，Help the construction of the project to achieve phased success，Press the Acceleration Key for the Construction of Nanjing Traffic Network。

Double-wheel slotting machine is mainly used for underground building enclosure、Design and construction of construction foundation，Applicable to various geological conditions，It is the first choice for hard rock geological construction nowadays.，Because of the high overall technical content、High value of single product，Be known as“The Pearl on the Crown of Piling Machinery”。The Nanjing Metro Line 6, which was built by Zhonglian Zhongke Double Wheel Milling, is located in the southern new town of Nanjing.，It is expected to open in 2024，When completed, it will connect to the airport.、High-speed rail、Qixia Mountain，And effectively alleviate the traffic pressure in the central city.。
The terrain of the project site is complex.，Strict control of slot accuracy，High requirements for construction quality of grooving machine。Engineering geology based on cutoff wall，Grooving accuracy、Comprehensive consideration of slotting speed，The project party selected Zoomlion Double Wheel MillingZC40 and Bao'e Hydraulic Grab cooperate in construction。Since entering the market in May this year,，ZC40 Perfectly matched construction method requirements，It has withstood the test of continuous high-intensity operation.，It alone completes 85 slot sections.，1.2 meters, 40 pieces, average 16～20 hours to complete one，1.45 meters, average 6～8 hours to complete one，With low failure、High efficiency、High quality has been unanimously praised by the project department and customers.。
