Recently, with the precise compaction of the final concrete into the mold, the construction of the first piece of concrete for the surface layer of the supporting dock expansion project of the Indonesian Golden Pulp Mill, which was constructed by China Harbour Engineering Group and implemented by the Third Navigation Bureau, has been successfully completed, marking the official entry of the project into a new stage of surface layer construction.

To ensure the smooth progress of the first piece construction, the project department attaches great importance to and plans ahead, focusing on the concept of "model led, quality first", and carefully preparing the construction plan. Through measures such as skill training, safety disclosure, and technical disclosure for local personnel, key links in the construction process are strictly controlled to ensure on-site safety production requirements.

The project is located in a tropical region with high temperatures throughout the year, and is currently entering the monsoon season. The apparent quality control of the surface layer is facing difficult challenges. In response to this situation, the project team adjusted the work plan, reasonably arranged the daily construction time, tried to avoid the high temperature period at noon, observed the weather in advance for the next week, and prioritized construction in the morning and evening when the temperature was relatively low, effectively reducing construction risks and ensuring work continuity.

There is a 0.5% bidirectional slope between the tracks, and the pouring elevation at the slab joints is not uniform, making the elevation control of the surface layer a major challenge. Through communication with the on-site team, the project team implemented a method of increasing the density of control points and reinforcing the elevation control points to prevent loosening during the pouring process. During the pouring process, the surveyor monitored the elevation of the surface layer to ensure the slope of the surface layer.

The first piece of surface layer concrete is poured with a length of 26.5 meters and a width of 18 meters, using C35 concrete. As the first piece of surface layer concrete construction, its apparent quality is good, with straight lines, neat joints, and consistent textures, which has received praise from the owner. The follow-up project team will continue to maintain efficient collaborative management, further optimize the construction process, strengthen quality and safety control, strive to achieve further breakthroughs in the construction period, fulfill the commitment to the owner with high-quality projects, and ensure the commissioning of the expansion project of the supporting dock of the Indonesian Golden Pulp Mill with a high level of progress.
