Chutian Golden News News / Special correspondent Li Guangzheng / special correspondent Liu everyone
At 8:45 am yesterday, the abutment on the south side of Majiawan Bridge in Leijiaqiao Village, Zhaoliqiao Town, Chibi City, 107 National Highway collapsed and traffic was interrupted, but no casualties and vehicle damage were caused. The relevant department decided to use the original 107 National Road (the old road) as a short-term bypass passage, and immediately organized the construction and repair, the passage will be completed within 24 hours.
on site
Collapsed nearly 20 meters
Break drop more than two meters
Majiawan Bridge is about 6 kilometers away from the new store toll station of Beijing-Hong Kong-Macao Expressway. Yesterday, the reporter drove the expressway from the Xindian toll station. The road was nearly 107 kilometers and was 107 National Road. Turn right and enter Zhaoliqiao Town. At the intersection, roads and public security departments have set up roadblocks to remind them that “the road ahead is repaired and the vehicles are forbidden to pass”. When the reporter rushed to the scene, he saw more than 10 workers under construction. They used yellow sand, cement and bricks to erect a wall at the north end of the Majiawan Bridge to remind the vehicle that it was a broken road. The reporter passed through the construction site and saw a crack about 20 cm wide and 5 cm deep on the bridge deck. Then the bridge deck sloped downwards. The south end of the bridge was completely broken. The drop was more than two meters and the collapse length was nearly 20 meters. The reporter saw that there are many stones on the fracture surface of the bridge and there is no steel bar. There are some stones and mud scattered on the ground, and there are also several cracks on the bridge.
Cry
A bus almost went to the break
The bridgehead on the north side of Majiawan Bridge is a bus shelter. When the reporter arrived at the scene, many CMB cars parked nearby, all of which were local buses. At about 9:00 am yesterday, a bus that was driven from Zhaoliqiao Town to Chibi City opened the Majiawan Bridge as usual. The ticket seller Chen Li (pseudonym) suddenly found that something was wrong. "How is the front black? If you look closely, it turns out to be a bridge." Chen Li said that after the driver found out, he quickly braked and stopped the bus. At this time, there was a car on the opposite side, and the driver did not seem to find that the bridge surface had collapsed. Chen Li quickly shouted loudly to the opposite side. "Called a few times, the opposite car stopped, when it stopped, it was only a few tens of centimeters from the crack on the bridge." Chen Li said with fear.
Measure
Vehicles bypass the old national highway and the Beijing-Hong Kong-Macau Expressway
According to reports, the Majiawan Bridge is 50.8 meters long and was built in 1989 as a 107 national highway highway bridge. After the bridge deck sank, the provincial transportation department, the highway bureau, Xianning City and other relevant responsible persons and technical experts rushed to the scene and actively took countermeasures. The traffic police department guides the diversion of vehicles blocked at the north and south. At the same time, the emergency headquarters decided to borrow the original 107 National Road (the old road) as a short-term bypass, and organized the construction to repair it yesterday morning to ensure that the passage was completed within 24 hours. After the old road resumes its capacity, small and medium-sized vehicles in the area can bypass the road, and the rest of the vehicles need to bypass the Beijing-Hong Kong-Macau Expressway. At the same time, the Majiawan Bridge Restoration Project initiated an emergency procedure, and reconstruction work is about to begin, ensuring that the vehicle will be completed and opened in the shortest possible time.
Quest
The original design standard is low, overloaded, etc. caused collapse
Wang Qing, director of the Quality Supervision Bureau of the Provincial Highway Bureau, said that according to the preliminary analysis, there are three reasons for the collapse: the design standard for the bridge was low in 1989, especially the collapsed part, which could not meet the increasing transportation load of these years; The masonry stone construction process (that is, after the stone is laid, it is filled with cement slurry), the method is rough, the backing material of the abutment position is poor, and the vehicle overload is intensified. Wang Qing said that according to the relevant regulations of Hubei Province, bridges like the Majiawan Bridge will be inspected and inspected every year, but there was no external inspection before the collapse. Wang Qing introduced that in 2011, the Majiawan Bridge was partially repaired, and the bridge will be demolished and rebuilt. At the same time, the Provincial Highway Administration will conduct a comprehensive survey of all bridges in the province similar to the Majiawan Bridge to prevent problems.
