Many ancient bridges were washed away
"Don't let a piece of Zhenhai Bridge Stone go to'stray'!"

Zhenhai Bridge was built in the Ming Dynasty. It is a 7-hole stone arch bridge with a length of about 131 meters. It is also a national key cultural relics protection unit. On July 7, the bridge body of Zhenhai Bridge collapsed, and the bridge deck part was basically washed away and seriously damaged.
On July 8, the Rainbow Bridge, Wuyuan County, Jiangxi, which is also a national key cultural relics protection unit, was also washed away by the flood to destroy the bridge deck and bridge corridor. This 140-meter-long ancient bridge has a history of more than 800 years, and was previously known as "out of print in the history of Chinese covered bridges".

In addition, the Lecheng Bridge in Jingde County, Anhui Province, also collapsed in the flood. According to incomplete statistics from the State Administration of Cultural Heritage, as of 16:00 on July 7, more than 130 immovable cultural relics in 11 southern provinces were lost due to floods.
Seeing so many ancient buildings damaged by the disaster, many netizens have such a question: In the face of the flood, why have these immovable cultural relics, such as hundreds of years old ancient bridges, become so fragile?
Why are ancient bridges so "fragile"?
In response to such problems, many media have conducted investigations recently.
An article pointed out that the idea of "protecting an ancient bridge is worse than building a new bridge for political achievements", which caused some of the ancient bridges to actually be in a state of loss. There are also reports that the repair and reinforcement projects of ancient bridges in some places are advancing slowly.
When a similar situation encounters a flood disaster, the destruction of the ancient bridge seems inevitable.

Wan Jinhong, a senior engineer at the China Institute of Water Resources and Hydropower Research, wrote in an article on the 13th that in the absence of professional flood prevention and mitigation measures, cultural relics buildings often suffer devastating blows when they are hit by floods.
Qiao Yunfei, deputy dean of the China Cultural Heritage Research Institute, admitted in an interview with a reporter from ChinaNews.com that the protection of immovable cultural relics like ancient bridges is indeed more subject to objective conditions. "The protection of ancient bridges is closely related to local river channels, topography, precipitation and disaster prevention capabilities."
He also pointed out, "The ancient bridges were built to meet the natural environment and traffic needs at that time. With the development of society, some local construction activities may fill up river channels that have been interrupted for many years. When the rain is small, these interrupted river channels It may have no effect, but when the rain is heavy, it must be a flood discharge channel."

"Let the ancient building have weather forecast"
In response to the issue of the safety of cultural relics in the flood season, the State Administration of Cultural Heritage has issued an emergency notice recently, requesting all cultural relics and museum units to effectively enhance disaster prevention and mitigation awareness, aiming at the destruction of ancient bridges, the collapse of ancient city walls, the collapse of ancient buildings and the dumping of ancient trees and famous trees, etc. Disaster risk, formulate plans for responding to major floods and geological disasters, and enhance emergency response capabilities for sudden disasters.
Qiao Yunfei told reporters that the State Administration of Cultural Heritage has always attached great importance to related issues. "Last year, the Ministry of Science and Technology and the State Administration of Cultural Heritage carried out the relevant work on'Removable Cultural Relics Natural Disaster Risk Assessment and Emergency Response Research'. The project was established at the end of last year, and work in this area is currently in progress."
Qiao Yunfei, as the project leader of the “Non-movable Cultural Relics Natural Disaster Risk Assessment and Emergency Disposal Research”, said, “From a prevention perspective, we need to study what kind of pre-measures can be taken under what kind of disaster level, To the greatest extent, avoid the impact of natural disasters on immovable cultural relics. For example, establish a normal mechanism for ancient building monitoring, collect and update relevant data, and determine the level of disasters that can withstand it. In addition, for flood disasters, combined with the study of the historical environment of ancient buildings and ancient sites, Flood relief and drainage facilities can be installed around ancient buildings and ancient sites through environmental remediation to prevent floods and waterlogging disasters."
"In terms of cultural relics protection, future warnings should be initiated, just like weather forecasts. Our ideal is that in the future, we will be able to issue early warning information to cultural relics and historic sites while warning of natural disasters. At the same time, once immovable cultural relics are affected Damage, you can make countermeasures as soon as possible." He said.

The reporter noticed that many relevant departments where the damaged ancient bridge is located have issued a notice that they will collect the ancient building components washed away and repair them as soon as possible.
According to reports, on July 11, Wuyuan, Jiangxi Province, confirmed that the rainbow bridge components found were: a beam between the east approach bridge and the No. 1 pier, five pieces, a flat plate, and several damaged and small components. Huangshan City has made it clear that it will salvage the raw materials of the Zhenhai Bridge washed down by the flood and repair it as soon as possible.
In this regard, Qiao Yunfei affirmed the relevant practices in the above places. "This is a method of post-disaster disposal. If the building components can be collected better and restored in the original form of the cultural relics, the damage to the cultural relics itself will be minimized." (End)
