The Shanghai Changxing Shipbuilding Base, located on Changxing Island in Shanghai, is a super‑large shipyard designed, planned, and built entirely in China. It represents a major milestone in China’s journey toward becoming a global leader in shipbuilding. Among its facilities, Dock No. 3—measuring 538 meters in length and 128 meters in width—is the largest dry dock in China, capable of constructing vessels and offshore platforms of every type worldwide. At the Shanghai Changxing Shipbuilding Base, all pile foundations for Docks Nos. 1, 2, and 3, as well as for the onshore areas, were constructed using a variety of pile types, including precast concrete square piles, tubular piles, CAZ steel sheet piles, and concrete sheet piles. The total pile‑foundation work amounted to 2.6 million linear meters, completed over a 30‑month construction period, with a single-phase deployment of more than 50 pieces of construction and transportation equipment. We successfully overcame numerous challenges, such as driving 32‑meter‑long Larsen steel sheet piles, installing ultra‑deep pile extensions reaching 25 meters into the pump house of the dock, and enduring the impact of Typhoon Matsa.
Land Foundation Treatment Project for the China Shipping Jiangsu Shipbuilding Base
The land‑based foundation treatment project at the China Shipping Jiangsu Shipbuilding Base covers an area of 1 million square meters. The project owner is China Shipping Industry (Jiangsu) Co., Ltd., and the total construction period is 43 days. Due to site constraints and the surrounding environment, various construction techniques were employed in different zones, including light wellpoint dewatering combined with dynamic compaction, impact rolling, vibro‑compaction, and plastic drainage boards.
Shenhua Dynamic Compaction Project
Construction of the full‑plant dynamic compaction works for the Shenhua Ningmei 4-million‑ton‑per‑year coal indirect liquefaction project (Section II) is being undertaken by the client, Shenhua Ningxia Coal Industry Group Co., Ltd. The project site is located in the Ningdong Coal Chemical Base (Area B6), Ningxia Hui Autonomous Region. The total area of ground improvement amounts to approximately 386,900 square meters, with dynamic compaction energy levels of 4,000 kN·m, 6,000 kN·m, 8,000 kN·m, 10,000 kN·m, and 12,000 kN·m. The overall construction period is 60 days.
Huizhou Dynamic Compaction Project
