Pass through the sea, and send electricity to the island with a pipe gallery!The latest progress of the project ...

【Electricity】

Turn into 2 20 kV cables

It helps to enter the island's third channel air cableization

【water】

Incorporate a DN1600 water pipe

It is expected to change the current status of a single water source on the island

The construction of Xiamen Electric Power and Shimizu Island Tunnel is expected to be fully rolled in July. The project is the third channel of the power of the island to enter the cableization and the civil construction of the island porch into the island. At present, the clearance work of the shield starting well has been completed, and the movement of the pipeline in the venue is close to the end.

The civil engineering engineering starts from the Songyu Power Plant in the west and crosses the western waters, and finally the island 220 kV Xiaxia Herchi power station. The main line is 6177 meters, of which the power tunnel of the land section is 3099 meters long and the outer diameter ranges from 3.6 meters to 4.2 meters. The project started in April this year and is expected to complete the construction of civil construction in 2026.

At present, Haicang Duan Shield has started construction. After completion, the shield machine goes deep into the well. This place is used as the departure station to dig into the bottom of the sea. The outer diameter of the tunnel tunnel after completion in the future can reach 6.7 meters. aisle.

Linking tunnels across the two districts and electric wires passed through the sea. After the project is completed, the "isolation belt" that restricts the development of Xiamen International Cruise Mother Port -the third passage of Electric Power's entry into the island will be closed into the tunnel. "As a coastal city, Xiamen is greatly affected by typhoons. As one of the main lines of power supply on Xiamen Island, the third channel of electricity is the island can effectively reduce the line failure rate during the typhoon." Li Bojun, the person in charge of the group.

In terms of water, Xiamen City's water uses water basically relies on cross -sea transportation. After the project is completed, the DN1600's clear water pipeline is connected to the island, which is expected to change the current status of a single water source -at present, the island mainly relies on two DN2200 to cross the sea pipe and the north lead can bear 50%of the urban water transmission. The nearest distance is about 3 meters, and the essence is a passage, with a water supply capacity of 780,000 tons/day.

According to the island's population growth and "Xiamen City Special Plan (2017-2035)", the island's recent (2025) water demand is 950,000 tons/day, and the maximum water demand will reach 1.2 million tons/day in long-term to 2035. Essence Therefore, the introduction of the second water source and increasing the passage of Qingshui into the island to meet the economic and social development of Xiamen and the needs of the normal life of residents.
