Small but complete. Cutter head, shield, rear support, 120 meters long fuselage set mechanical, electrical, hydraulic and other systems in one. "the equipment has many functions, such as excavation, support and slag extraction, and is no different from large diameter shield machines in terms of performance and construction efficiency."

Sri Lanka is an island country in the Indian Ocean and an important hub of the Maritime Silk Road. In the middle of the island are towering peaks and lowlands in the surrounding coastal areas. During the rainy season Rain Water poured down the hillsides, causing coastal residents to suffer from flooding. In order to solve the problem that the old drainage network could not meet the problem of flood discharge, the Sri Lankan government built the New Mattuwa and Torrington drainage works through international bidding.
