The Cantilever Dredger Ship 277 is a self-developed construction vessel by our company, featuring innovative equipment, powerful capacity, and high performance efficiency. It can directly excavate hard soil, clay, siliceous sandstone, fully weathered rock, strongly weathered rock, moderately weathered, and other relatively hard geological formations. It can perform direct excavation without blasting and has good performance and high productivity. For high-strength hard weathered rock, it be equipped with our company's self-developed and patented high-frequency crushing hammer or hydraulic crushing hammer for preprocessing of rock and soil crushing, and then carry out strong digging to meet increasingly stringent environmental requirements. The ship's body uses steel pipe piles for construction positioning, which has little impact on navigation. The vessel is equipped with a 3D guidance system to assist in excavation depth and an RTK positioning system. With the assistance of both systems, the accuracy of underwater construction reaches within 5 cm, meeting various types underwater construction requirements. Direct strong excavation of weathered rock refers to strength: 20Mpa, high-frequency crushing hammer auxiliary preprocessing of weathered rock refers to strength: 30Mpa, hydraulic crushing hammer auxiliary preprocessing of weathered rock refers to strength: 50Mpa.
