Reasonable construction of outer reef island

How to arrange construction organization and cost control is the key link faced by the project department. First of all, carefully prepare the list of all kinds of ships, equipment, measures and materials needed for the project, and negotiate repeatedly to determine the most reasonable scheme. Secondly, relying on the company and Yangkou Project Department, the berthing members are commissioned to prefabricate, and the remaining or dismantled measures and materials of Yangkou Project Department are deployed to avoid re-purchasing and reduce the procurement cost as much as possible. Thirdly, use the knowledge and experience of offshore construction of Yangkou Project Department to guide the offshore construction of our project department. Fourth, on the leased 2000-ton barge, the living area and production area were changed, and the container was transferred and changed into the living area of migrant workers through the coordination of Yangkou project; At the same time, considering the needs of offshore construction, we rented 1 55T crawler crane to reinforce the bow and changed it into offshore floating crane in disguise, which reduced the cost of increasing offshore floating crane and saved about 65,438+10,000/month in disguise. Fifth, add a 250-horsepower maritime transport ship to ensure the supply of daily necessities and materials needed for the production of hungry ships. At the same time, the ship can anchor sea anchors weighing more than 1.5 tons, which avoids the project department from renting anchor boats again, increasing the cost and reducing the cost by about 1.3 million/month.

Secondly, in view of the discontinuous construction process caused by the sea weather, the project department used fine weather to speed up the construction progress. During the sinking of No.7 pile, a strong wind of Grade 9 broke out at sea. After filling the teeth, it took only 5 days to complete the task of sinking 20 piles at a distance of 26 nautical miles. In the construction of pile caps, the original technology was changed, and the construction process of pile caps was changed to installing side formwork-installing berthing members-laying bottom formwork-binding steel bars, which greatly accelerated the construction speed of pile caps. At the same time, some small details are optimized to ensure the progress of the overall construction of the pile cap. (Zou Xinxiang)
