Excavator Rock Saw Excavating Tunnel With High Efficiency

2022-10-13

The saw blade of the excavator rock saw is made of artificial diamond, which is the hardest substance in nature, so the rock saw can cut extremely hard rocks. Especially in the process of digging tunnels, hard rocks, such as basalt, are often encountered. At this time, there is no way to dig with equipment such as a drum cutter, and a rock saw needs to be used to cut it.

Take a tunnelling project in Xiamen, Fujian Province as an example. Most of the mountains here are dominated by basalt, which has the characteristics of high hardness, high strength and good wear resistance. Rocks have a Mohs hardness of between 5-7 and are difficult to cut and break with conventional equipment. The construction party used the YS-20SS rock saw provided by Yichen Company and installed it on the Carter 320 excavator to achieve the goal of easily cutting the basalt rock mass.

The specific construction method is to use a rock saw to cut two slits at an interval of 5 cm on the face of the face, the depth of the slit is about 50-100 cm. Then crush the middle, and then use a stone splitter to break the middle as the center, and punch two rows of holes about 0.5 meters apart for hydraulic cracking. In this way, it goes on and on, cutting and crushing continuously, and it can reach a depth of 4-5 meters a day. The effect is remarkable, which greatly improves the efficiency of tunnel excavation.
