The contract value of the N108 section of the Singapore North-South Corridor project is approximately RMB 2.24 billion, which requires the excavation of a continuous wall and the construction of a two-way six-lane underground tunnel. Due to the huge amount of continuous wall engineering, multiple two-wheel groove milling machines are required to ensure the speed and quality of the wall.
The XCMG XTC80/85 double-wheel groove milling machine has small deviations in wall verticality and high accuracy. It can achieve complete rock fragmentation and smooth groove walls without dead corners. The wall has excellent water-cutting, anti-seepage, load-bearing and water-retaining performance.
Under the granite stratum, the power output of the XCMG double-wheel groove milling machine is unreserved, cutting the rock like mud, and the verticality is completely within the deviation range. The perfect presentation is 2.8m wide, 1.2m thick, and 40m deep. The continuous wall construction of the project has achieved a good start. ! The on-site personnel measured the hardness of the milled gravel and found that the rock hardness reached 180MPa-200MPa. Under this extremely challenging working condition for double-wheel milling, XCMG double-wheel milling maintained a monthly workload of 4-6 continuous walls in the subsequent construction.
Because of the small land area, Singapore is committed to the process of building an underground city, and the demand for underground space construction is accelerating. The project party decided to continue to purchase double-wheel milling when there was still a large number of continuous walls to be completed and the construction period was tight. The construction team’s leadership quickly decided to purchase two additional XCMG XTC80/85 double-wheel groove milling machines, which have been put into use at present, and the construction is as high-quality as before.
In recent years, the export sales of XCMG's basic construction machinery segment in Southeast Asia has doubled, and it will continue to build high-value brands and high-quality products, and use the "key of innovation" to open the "lock of growth", playing the strongest role in China's manufacturing in the world. sound.
