Construction crews yesterday morning laid the first pier foundation for the Kinmen Bridge (金門大橋), the National Freeway Bureau said, adding that it is confident that the bridge would be finished by 2021.
The bridge would connect Greater Kinmen (大金門) and Lieyu (烈嶼, also known as Little Kinmen), the two main islands in the county, the bureau said.
It would span a strip of sea whose bed is on average 7m below the surface, it said, adding that in some areas the seabed is about 20m below the surface.
The geological complexity has made it impossible to lay the pier foundations using steel sheet piles, so the construction crews used the steel cofferdam method, the bureau said.
This was the first time the method was used by the bureau to lay a pier foundation, which took two months to complete, it said, adding that it should be able to lay the other pier foundations faster.
The bureau in March laid a foundation pile on granite.
The bureau yesterday explained the challenges of applying the steel cofferdam method.
The crews first installed jacketed steel pipes as a support base before beginning the construction, it said.
They assembled the steel cofferdam on land before lowering it to a designated depth using 12 large hydraulic jacks, the bureau said, adding that divers worked 3m to 9m below the sea surface to install bottom boards for the cofferdam and seal the plates between jacketed steel pipes.
Crews then pumped in concrete to form a 1.5m-thick bedding at the bottom of the cofferdam before pumping out the seawater trapped inside the structure, it said.
The cofferdam had to withstand buoyancy of more than 1,000 tonnes and tidal effects twice per day, the bureau said, adding that the crews installed six jacketed steel pipes and buoyancy-resistant steel piles to reinforce the structure.
Divers were kept on standby during the construction in case seawater leaked into the cofferdam, it said.
The bridge project has been criticized for “only surfacing during elections.”
The Legislative Yuan’s budget center has said in a report that the project had several issues, such as low budget implementation efficiency and construction delays.
Proposed legislation in the US outlines three conditions in which Washington would be authorized to protect Taiwan were China to invade, a report said yesterday. US Representative Ted Yoho this month said he would introduce a Taiwan Invasion Prevention Act, which would authorize US military force if China were to invade Taiwan-controlled areas, including its outlying islands. According to a version of the bill obtained by the Chinese-language Liberty Times (the sister paper of the Taipei Times), the bill lists three conditions in which a US president would be authorized to use military force to protect Taiwan: If China uses military force
The Supreme Court on Tuesday found four men guilty of attempted murder in the 2017 stabbing of Spanish surfer Ignacio Prio on a Pingtung County beach in the final ruling in the case, sentencing them to three-and-a-half to six years in prison. The defendants had appealed their convictions for attempted murder in the first and second rulings, which had also led to prison sentences ranging from three-and-a-half years to six years. The then-42-year-old Prio went to Jialeshui Beach (佳樂水) near Kenting (墾丁) on March 31, 2017, was attacked after he asked four men to remove their fishing lines from an area
Two new commuter trains are scheduled to be launched in January next year, the Taiwan Railways Administration (TRA) said yesterday. The acquisition of EMU-900 commuter train cars is part of the railway operator’s plan to replace 589 train cars that have been in operation for more than three decades. The agency has also placed orders to buy 600 intercity train cars. The first batch of 20 EMU-900 cars is to be delivered to the nation in September, although delivery might be delayed until October due to the COVID-19 pandemic, the agency said. The batch would be formed into two trains of 10
‘IMMORAL, INSINCERE’: Huang Kun-huei said that Ma was ‘distorting history’ in claiming that Lee Teng-hui laid the foundation for the so-called ‘1992 consensus’ Former Presidential Office secretary-general Huang Kun-huei (黃昆輝) on Saturday rejected former president Ma Ying-jeou’s (馬英九) claim that former president Lee Teng-hui (李登輝) had been a proponent of Beijing’s “one China” principle. Lee, who served as president from 1988 to 2000, died in Taipei on Thursday last week. After visiting the Taipei Guest House on Saturday to pay his respects to Lee, Ma posted on Facebook that “28 years ago on this day” Lee hosted a session of the now-defunct National Unification Council, during which he passed a resolution on the “one China” principle. That resolution became the basis of the Chinese Nationalist Party’s
