Zhenhai Refining & Chemical’s 1-million-ton-per-year ethylene project is the first in China to directly achieve an annual production capacity of one million tons. The project has received high-level attention from both the Zhejiang Provincial Party Committee and Sinopec headquarters; at the time, Xi Jinping, then Secretary of the Zhejiang Provincial Party Committee, personally presided over the groundbreaking ceremony. This milestone laid the foundation for Zhenhai Refining & Chemical to become the industry leader in both profitability and refining scale. Our company was primarily responsible for constructing the pile foundations for the ethylene cracking unit, the district utility tunnel, as well as the external process heating pipelines for propylene oxide, styrene, and the entire plant, completing a total of 90,000 cubic meters of piling work.
The Sinopec Tianjin Crude Oil Commercial Storage Facility, one of the largest storage complexes in North China, is an important crude oil storage project for Sinopec in the Beijing–Tianjin–Hebei region and represents the company’s single‑phase, largest‑scale domestic inventory‑construction initiative. The company has successfully completed the fabrication and installation of pile foundations for Sections 5, as well as portions of Sections 1 and 2, totaling 55,000 cubic meters of precast concrete square piles fabricated and installed on site, earning high praise from the Sinopec Pipeline Bureau.
The Sinopec Tianjin National Crude Oil Storage Facility, located in the Binhai Development Zone of Tianjin and adjacent to the Bohai Sea, is one of the largest crude oil storage projects in North China. Commissioned by the National Development and Reform Commission, it is a major national strategic oil reserve complex managed and constructed by Sinopec. The project involves the simultaneous construction of 32 100,000-cubic-meter crude oil storage tanks, playing a crucial role in safeguarding the nation’s strategic oil reserves. Through meticulous planning and scientifically sound execution, our company completed, on schedule, the fabrication and installation of 7,500 concrete bored piles totaling 63,000 cubic meters for Section III in just 190 days, with all results fully meeting design specifications.

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.

The Senlan International Community Commercial Building A4‑2 project is located in the Senlan area of Shanghai’s Waigaoqiao Free Trade Zone. The main structure comprises five above‑ground floors, housing commercial spaces, community services, and sports facilities, while the three underground levels accommodate two levels of retail space and a three‑level parking garage. For this project, static‑pressure pipe piles are used for the two‑story section, whereas bored cast‑in‑place piles are employed in the three‑story section. The excavation pit covers an area of 33,118 m², with depths ranging from 11.3 to 16.65 m. Sequential full‑pit excavation is adopted. In the second basement level, the retaining system consists of row piles combined with triple‑axis jet grouting cutoff walls and two horizontal concrete bracing members. In the third basement level, the design features a diaphragm wall (with rubber waterstop joints), triple‑axis jet grouting wall reinforcement, and three horizontal concrete bracing members. In areas with elevation differences, the retaining system utilizes bored cast‑in‑place piles together with an ultra‑long triple‑axis cement‑soil jet grouting cutoff wall.
New Commercial and Residential Development on Senlan Island
The new residential and commercial development on Senlan Island is located in the Senlan area of Gaoxing Town, Pudong New Area. It covers a land area of 226,000 square meters, with a total floor area of approximately 272,000 square meters—156,000 square meters underground and 116,000 square meters above ground—and is divided into nine parcels. Our company is responsible for pile foundation and excavation shoring works. The pile foundations consist of pre-stressed hollow square piles, totaling about 400,000 linear meters, while the excavation shoring system primarily comprises jet-grouting diaphragm walls, internal steel sections, and localized diagonal bracing.

Shanghai Lingang Ice and Snow Star is located in Nanhui New City, Shanghai’s New Area. The project employs two types of pile foundations: precast pipe piles and bored cast-in-place piles. In the basement’s general areas, the bottom slab elevation is –7.80 m, with a slab thickness of 700 mm and a leveling layer thickness of 150 mm. In the southeast corner—where the boutique hotel is situated—and in the northeast corner—within the northern resort‑hotel zone—the typical excavation depth is 6.45 m. In certain localized areas of the northwest corner, the typical excavation depth is 7.75 m. Sump pits are 1.50 m deep, elevator shafts are 1.50 m deep, and elevator fire‑fighting sump pits are 3.00 m deep. For the basement area of this excavation, the retaining structure consists of bored cast-in-place piles combined with a single‑row triple‑axis cement‑soil mixing pile cutoff wall, with an internal reinforced concrete support system. The cutoff wall is constructed using ∅850@600 triple‑axis cement‑soil mixing piles. Within the excavation, reinforcement is achieved through 700@500 double‑axis mixing piles supplemented by compaction grouting.
