【on.cc東網專訊】深圳灣公路大橋往香港方向高架橋一條直徑160毫米的外置式預應力鋼纜折斷，路政署署長陳派明今午(16日)表示，署方昨日(15日)在深圳灣大橋進行例行檢查時發現鋼纜折斷，經專業人員檢查後，認為結構安全。因應監察和維修需要，公路往香港方向已實施臨時交通措施，向香港方向的三條行車線中暫封兩條，交通仍暢順。陳強調，大橋考慮結構設計時已預留足夠安全系數，少一條鋼纜仍可正常行車。

陳指，昨日中午發現事件，初步相信是銹蝕所致，相信屬個別事件，鋼纜折斷並不常見。由於鋼纜有灌漿保護，故從外面看不出銹蝕。鋼纜分外置及內置兩部分，內置有40條鋼纜，外置6條，今次折斷是外置的其中一條。

他稱，對上一次檢查鋼纜於去年9月，約2星期前檢查大橋其他事宜時，都沒有發現異樣。署方已安排承建商於3星期內更換受損部分，但需視乎適當物料及工具安排。

署方已巡查大橋其他鋼纜，並無發現異樣及確定結構安全，當局會詳細檢查受損鋼纜找出原因，並專家測試其他鋼纜狀態，冀3個月內完成檢視其他同類設計的橋樑，包括青衣北橋及8號幹線公路等。

[on.cc East Network News] Shenzhen Bay Road Bridge to Hong Kong direction viaduct 160mm diameter external prestressed steel cable broken, the Director of Highways Department Chen Pai Ming said this afternoon (16th), the Department yesterday (15th) During the routine inspection of the Shenzhen Bay Bridge, it was found that the steel cable was broken. After inspection by professionals, the structure was considered safe. In response to the need for monitoring and maintenance, the Highway has implemented temporary traffic arrangements in the direction of Hong Kong and temporarily sealed two of the three lanes in the direction of Hong Kong. The traffic is still smooth. Chen stressed that the bridge has reserved sufficient safety factor when considering the structural design, and one less steel cable can still drive normally.

Chen Zhi, who found the incident at noon yesterday, was initially believed to be caused by rust. It is believed that it was an individual incident and the cable was broken. Since the steel cable has grout protection, no rust is visible from the outside. The cable is divided into two parts, external and built-in. There are 40 steel cables and 6 external ones. This time, the broken one is one of the external ones.

He said that the last time the steel cable was inspected last September, about two weeks ago, when checking other matters on the bridge, nothing was found. The Department has arranged for the contractor to replace the damaged part within 3 weeks, subject to appropriate materials and tools.

The department has inspected other steel cables of the bridge. No abnormalities have been found and structural safety has been determined. The authorities will examine the damaged steel cables in detail to find out the reasons. Experts will test the status of other steel cables and complete the inspection of other similar design bridges within 3 months. , including Tsing Yi North Bridge and Route 8 Highway.

These cables are hidden inside the strength members of structure. Typically Beams. 死扑街! faster inspect and replace all rusty cables!

The project was planed 2003, finished construction 2006 and begin service 2007. Is some one forging maintenance records? Got corruption?

How many bridges have they got going from hong kong to shenzhen? I thought it was recently completed?

How many bridges have they got going from hong kong to shenzhen? I thought it was recently completed?

Possible 10 or more.

A river divided the territories for centuries. Any checkpoint crossing goes via some bridge. See water below.

Fugitives and illegal migrants used to swim across. There are too much fence and deliberately build obstacles like walls and barriers now. Too many CCTVs 24hrs.

Yet they can still fuck around using drones and ropes etc to smuggle.





Got fucking tunnel caught! 地道战!

 

[Shut Up you are Not MM]

Pre-casted Pre-Stressed Concrete Beams, got bunch of cables inside. If the bridge was from 2007, their beams would had been made in 2204/2005 for construction in 2016. Inside chamber of the beams can be very moist and invaded by SEA WATER SALT during e.g. Typhoon. Rusty can break in 10 years can be expected. Time to replace whole batch.

■深圳灣公路大橋通車不足十二年，發現一條鋼纜折斷，路政署稱結構仍然安全。
【星島日報報道】（星島日報報道）於二○○七年建成、橫跨后海灣的深圳灣公路大橋通車不足十二年，路政署近日發現大橋往香港方向行車線的高架橋梁，一條外置鋼纜折斷，相信是鏽蝕所致。路政署署長陳派明昨表示，鋼纜折斷不是常見現象，但設計時已有預留足夠的安全系數，道路結構仍然安全，現時大橋往香港方向的其中兩條行車線已暫時封閉，料三星期內完成更換。
全長約五點五公里、三線雙程分隔車道，連接香港流浮山及深圳蛇口的深圳灣公路大橋，通車不足十二年，路政署署長陳派明昨日表示，署方前日在深圳灣公路大橋進行例行檢查期間，發現往香港方向行車線的一條高架橋梁，其中一條直徑約一百六十毫米外置式預應力鋼纜折斷。他解釋，高架橋梁以混凝土橋板架設在橋墩上，並以多條內置式及外置式鋼纜連貫組成結構組件，職員已檢查其他鋼纜，並沒有發現異常情況，而橋梁結構專家亦到場進行特別檢查，均認為結構安全並沒有受影響，可以繼續行車。
陳派明表示，由於鋼纜有灌漿保護，從外面看不出鏽蝕。署方上一次進行鋼纜檢查是在去年九月，當時未有發現異常情況，其後在兩星期前檢查大橋其他部分時，亦沒有異樣。惟在前日下午進行大橋其他檢查時，發現有外置式預應力鋼纜折斷。據初步估計，折斷是因為鏽蝕所致，未來會提取鏽蝕的部分進行試驗，包括金屬物料試驗，以找出折斷的原因，陳又指，大橋建造時有一套審慎的監測機制，需符合機制才可容許大橋通車，相信鋼纜的物料是符合當時要求。
深圳灣大橋現時設有四十條內置鋼纜及六條外置鋼纜，陳派明表示在大橋設計時，已有考慮需要更換鋼纜，因此設計時已預留足夠的安全系數，「在更換鋼纜時，即使在缺少其中一條鋼纜時，橋面仍可以正常行車。」他補充，涉事地點位於香港境內，無論設計、建造、維修、保養等都是由香港的承建商負責。
陳派明說，署方已聯絡安裝鋼纜的承建商，三星期內完成更換鋼纜，「要取決能否安排適當物料，及工具能否安排，希望可以盡快更換。」他強調，相信事件屬個別事件，「鋼纜折斷不是常見現象，我們不會掉以輕心。」他預計，會在未來三個月逐一檢視全港類似的鋼筋橋梁，包括內置鋼纜，而青衣北橋及八號幹線公路亦採用類似方法設計。深圳灣公路大橋現時往香港方向的三條行車線，其中兩條已暫時封閉。

■ The Shenzhen Bay Highway Bridge was opened to traffic for less than 12 years and a steel cable was found broken. The Highways Department said that the structure is still safe.

[Sing Tao Daily Report] (Sing Tao Daily reported) The Shenzhen Bay Highway Bridge, which was completed in 2007 and spanned the Deep Bay, was opened to traffic for less than 12 years. The Highways Department recently discovered an elevated bridge leading to the Hong Kong direction of the bridge, an external The cable is broken, which is believed to be caused by rust. The Director of Highways, Mr Patrick Chan, said yesterday that the breakage of steel cables was not a common phenomenon. However, sufficient safety factors were reserved at the time of design. The road structure was still safe. Two of the existing lanes of the bridge to Hong Kong were temporarily closed. Replace it within the week.

The Shenzhen Bay Road Bridge, which is connected to Hong Kong's Lau Fau Shan and Shekou, Shenzhen, is about 5.6 km long. It is less than 12 years old. The Director of Highways, Mr Chan Pai-ming, said yesterday that the Department had conducted the Shenzhen Bay Road Bridge the day before. During the routine inspection, an elevated bridge leading to the Hong Kong direction of the traffic lane was found. One of the external prestressed steel cables with a diameter of about 160 mm was broken. He explained that the elevated bridge was erected on the pier with concrete bridges and consisted of multiple built-in and external steel cables. The staff had inspected other steel cables and found no abnormalities. The bridge structure experts were also present. Special inspections were carried out and the structural safety was considered to be unaffected and the vehicle could continue to operate.

Chen Pai Ming said that due to the grouting protection of the steel cable, no rust is seen from the outside. The last time the department conducted the cable inspection was in September last year. No abnormalities were found at that time. It was not the same when the other parts of the bridge were inspected two weeks ago. However, when the bridge was examined in the afternoon of the previous day, it was found that the external prestressed steel cable was broken. According to preliminary estimates, the breakage is caused by corrosion. In the future, the rusted part will be tested, including the metal material test, to find out the cause of the break. Chen also pointed out that there is a prudent monitoring mechanism when the bridge is built. The bridge can be allowed to open to traffic, and it is believed that the materials of the steel cable meet the requirements at that time.

The Shenzhen Bay Bridge currently has 40 built-in steel cables and six external steel cables. Chen Pai Ming said that when designing the bridge, it has been considered to replace the steel cables. Therefore, sufficient safety factor has been reserved during the design. When replacing the steel cable, even in the absence of one of the steel cables, the bridge deck can still operate normally." He added that the location is located in Hong Kong, regardless of design, construction, maintenance, maintenance, etc., which are the responsibility of the contractor in Hong Kong.

Mr Chan said that the department had contacted the contractor who installed the steel cable. Samsung completed the replacement of the steel cable during the period. "It depends on whether the appropriate materials can be arranged and whether the tools can be arranged. I hope that it can be replaced as soon as possible." He stressed that he believed that the incident was In the case of individual incidents, "Steel cable breakage is not a common phenomenon. We will not take it lightly." He expects to examine similar steel bridges in Hong Kong one by one in the coming three months, including built-in steel cables. The Tsing Yi North Bridge and Route 8 are also used. Similar method design. The three lanes of the Shenzhen Bay Highway Bridge to the Hong Kong direction are now temporarily closed.

八號幹線
八號幹線公路當中包括昂船洲大橋，全長一千六百米。
受深圳灣公路大橋鋼纜折斷事件影響，當局亡羊補牢急急檢查全港同類橋樑，包括青衣南橋及八號幹線公路等。路政署署長陳派明指出，會在三個月內檢視其他同類設計的橋樑，又強調該署一直有周詳的保養維修計劃，有信心其他橋無問題，惟暫未能提供相關名單。深圳灣公路大橋的承建商為金門建築，承建多項道路及橋樑工程，而大橋的工程顧問公司為奧雅納，近年亦捲入多宗極具爭議事故。

陳派明昨日在記者會上表示不會掉以輕心，並且會小心檢視其他同類橋樑。他對其他橋樑的狀態有信心。

不過為審慎起見，其他類似設計的外置式預應力鋼筋都會盡快進行檢查，估計希望可以於三個月檢視到。他又說：「全港用這個方法建造的橋樑都幾多。」但路政署暫未能提供這些橋樑的名單。

捲多宗爭議 工程顧問曾「停賽」

俗稱青衣南橋的青衣大橋建於一九七四年，長六百一十米，離海面高度廿六米，供車輛和行人使用，耗資一千七百萬元。而八號幹線公路當中包括昂船洲大橋，造價卅七億元，全長一千六百米，其重要設計包括長一千零十八米的鋼製主跨，由兩座二百九十米高的混凝土與不銹鋼橋塔支撐，五十三米寬的橋面分為兩個流線形鋼箱，由交叉橫樑連接而成。

昂船洲大橋的工程顧問也是奧雅納。奧雅納近日捲入港珠澳大橋遲交一萬四千份檢查及測量申請表格事件，而在二○一六年，奧雅納挪用政府資料，為橫洲的私人住宅項目作規劃申請。發展局指奧雅納沒有遵照政府的顧問合約條款，暫停其投標政府顧問合約，為期三個月。

復修大館亦出事 承建商遭控告

至於深圳灣公路大橋的承建商金門建築，亦承建多項道路及橋樑工程，包括廿億元的后海灣幹線北段工程、八十億元的屯門至赤鱲角連接路—南面連接路高架道路段、六億元的青山公路改善工程合約等。而金門建築近年捲入的工程事故有大館倒塌；有逾一百五十年歷史、俗稱大館的中區警署建築群，其中已婚督察宿舍於復修工程期間倒塌，金門建築被控進行嚴重偏離批准圖則所顯示的工程，以及工程導致財產損毀。

Among the Route 8 is the Stonecutters Bridge, which is 1,600 meters long.

Affected by the steel cable breakage incident of the Shenzhen Bay Highway Bridge, the authorities have rushed to check the similar bridges in Hong Kong, including the Tsing Yi South Bridge and the Route 8 Highway. The Director of Highways, Mr Patrick Chan, pointed out that the bridges of other similar designs would be inspected within three months. The department also stressed that the department had been well-maintained with maintenance and repair plans. It was confident that other bridges would be problem-free, but the relevant list could not be provided. The contractor of the Shenzhen Bay Highway Bridge is a Golden Gate building, which has built a number of roads and bridges. The engineering consultancy of the bridge is Arup. In recent years, it has also been involved in many controversial accidents.

Chen Pai Ming said at a press conference yesterday that he would not take it lightly and would carefully examine other similar bridges. He has confidence in the state of other bridges.

However, for the sake of prudence, other pre-stressed steel bars of similar design will be inspected as soon as possible, and it is estimated that they can be viewed in three months. He added: "There are many bridges built in Hong Kong by this method." However, the Highways Department has not been able to provide a list of these bridges.

The volume of disputes has been suspended by the project consultant.

It costs $17 million. The Route 8 Bridge includes the Stonecutters Island Bridge at a cost of $700 million and a total length of 1,600 metres. Its important design includes a steel main span of 1,080 metres and two 290 metres. High concrete and stainless steel pylon support, the 53-meter-wide bridge deck is divided into two streamlined steel boxes, which are connected by cross beams.

The engineering consultant of the Stonecutters Bridge is also Arup. Arup has recently been involved in the Hong Kong-Zhuhai-Macau Bridge late payment of 14,000 inspection and measurement application forms. In 2016, Arup used government information to make planning applications for the private residential project in Hengzhou. The Development Bureau stated that Arup did not comply with the terms of the government's consultancy contract and suspended its bidding for government consultant contracts for a period of three months.

The repairing hall also had an accident. The contractor was charged.

As for the contractor of the Shenzhen Bay Road Bridge, the construction of a number of roads and bridges, including the North Section of the Deep Bay Link of $100 million and the Link Road of Tuen Mun to Chek Lap Kok. Section, 600 million yuan Qingshan Road improvement project contract. In the past few years, the construction accidents involved in the construction of the Golden Gate building have collapsed. The Central Police Station complex, which is more than 150 years old and commonly known as the Great Hall, has collapsed during the renovation period. The Golden Gate building was accused of serious damage. Deviation from the works shown in the approved plan, as well as the project causing property damage.
