On April 15, Zhejiang officially entered the flood season.
According to the meteorological forecast, it is expected that this year's flood season in Zhejiang Province will be accompanied by drought and flood, and waterlogging will be heavier than drought, and the overall deviation of hydrometeorological yearscape will occur.
In the past two days, on the Chao News "Reporter Gang" () platform, some netizens have sent consultations, the precipitation in the flood season is large, for some museums in Hangzhou, many of the exhibitions are extremely precious, in such weather, how to ensure that they are not moldy or damaged?
"Especially in the Southern Song Dynasty Deshou Palace Ruins Museum, many of them are real ruins underground, when the flood season comes, how to prevent moisture and ensure that the real ruins are not damaged?"
Today, the Chao News reporter had an exclusive conversation with the person in charge of the cultural preservation work of the Deshou Palace Ruins Museum in the Southern Song Dynasty to understand how they protect these precious ruins.

Further strengthen the monitoring of the groundwater level at the site
Make sure rainwater does not infiltrate the site
Indeed, compared with many existing museums in Hangzhou, the Southern Song Dynasty Deshou Palace Ruins Museum is too special, and the most classic part of the museum is these real ruins hidden underground.
In the Southern Song Dynasty Deshou Palace Ruins Museum, the ruins are mainly concentrated in two areas of the museum.
One is the main hall of Chonghua Palace and the archaeological achievements of Deshou Palace, which is the "Central District Ruins". The main content is the display of the ontology of the main hall site in the central district, the interpretation of important sites, the four archaeological excavation processes and archaeological results of Deoksugung Palace. The other is larger, which is the ontology display area of Cifu Palace and related garden ruins, referred to as "West District Ruins", which mainly includes the display and interpretation of 17 ruins and related unearthed cultural relics in the West District.
At present, the protection of these two sites is under the responsibility of Baiyun Cultural Conservation.
Every day, Ye Weiming, the person in charge of the site, has to inspect these two sites, and under daily circumstances, he has to inspect twice in the morning and afternoon to see if there is any water seepage in these sites, and whether there are some changes in the site itself.
After entering the flood season, the frequency of such inspections will naturally increase.
"After the flood season, we will further strengthen the monitoring and monitoring of the groundwater level of the site, regularly conduct on-site inspections and online monitoring of whether the water collection well pump is working properly, and at the same time, we will also pay special attention to the inspection of the pumping facilities of the sunken square outside the northwest corner of the western area, and when it rains, the on-site inspection should also be extra careful to ensure that rainwater does not seep into the site. Ye Weiming said.
Why does the sunken plaza on the outside of the northwest corner of the West District need to be paid attention to?
Ye Weiming said that because there have been some water seepage cases here before, similar to these problematic points, in the flood season inspection, it is necessary to take extra "care" to ensure that nothing goes wrong.
"There may also be water seepage in the part of the site against the wall, usually the precipitation is not large, it may not be so obvious, and once it enters the flood season, with the increase of precipitation, if the rainwater accumulates for a long time, it may lead to outdoor rainwater infiltration, so we must also pay special attention. ”

Temperature, humidity, light and other monitoring equipment are readily available
Timely manual intervention if there is an abnormality
Of course, the site display area in the Southern Song Dynasty Deshou Palace Ruins Museum is still quite large, and it is naturally a little too much to take care of just a little manual inspection. At this time, it is necessary to rely on a series of "monitoring devices" installed in the museum to monitor the whole process, and once the value is abnormal, the background will find it in time.
For example, at the water collection well, there is a water level monitoring device, once the water level exceeds the early warning, manual timely intervention is required.
In the museum, temperature, humidity, light and other monitoring equipment are also readily available.
"The temperature settings in the exhibition area are all regulated, for example, no higher than 26°C in summer and no less than 10°C in winter. The relative humidity is set to no more than 70%, and the relative humidity difference between day and night is not more than 5%, etc., once the data is exceeded, we will manually intervene to regulate the indoor temperature and humidity. Ye Weiming said.
In addition, daily inspections around the site will be strengthened, and problems such as water leakage and seepage will also be reported in a timely manner, including timely treatment of microorganisms such as mold, algae and other microorganisms on the site.
Ye Weiming told the Chao News reporter that on the whole, the current protection of the site is still very good, the state of cultural relics and the site is relatively stable, and any problems can be dealt with in time.
In addition, last week, in order to optimize the daily reception and management of the museum and improve the visiting experience of tourists, the Southern Song Dynasty Deshou Palace Ruins Museum was closed for a period of 5 days.
The closure of the museum is mainly to upgrade and transform the hardware in the museum. For example, basic repairs have been carried out to the wooden floors in the museum, including the elimination of abnormal noises on some wooden floors, so that everyone can be more comfortable when visiting the museum.
"Since its opening in November 2022, the Southern Song Dynasty Deshou Palace Ruins Museum has received more than 1 million citizens and tourists, and in the process of tourists, the wooden buildings in the museum, including the stone at the entrance, will also be more or less damaged. So, this time, we spent five days intensively adjusting and optimizing these problems. Zhou Ji, head of the Southern Song Dynasty Deshou Palace Ruins Museum, said.

How to prevent moisture and mildew from other cultural relics in Hangzhou
In addition to the Southern Song Dynasty Deshou Palace Ruins Museum, there are also many readers who are concerned about how the cultural relics in other museums in Hangzhou are moisture-proof and mildew-proof, and what specific measures are taken by Hangzhou for the safety precautions of cultural relics during the flood season?
The Chao News reporter also contacted the Security Department of the Hangzhou Municipal Bureau of Gardens and Cultural Relics, and the relevant person in charge revealed that under normal circumstances, the main method of moisture and mildew prevention of cultural relics in the museum is to use constant temperature and humidity equipment to adjust the temperature and humidity 24 hours a day. If the humidity in the warehouse is particularly high, a dehumidifier will be used to remove the humidity.
At present, in view of the safety precautions of cultural relics in the flood season, the cultural relics management department has mainly strengthened the following four aspects:
1. Strengthen daily inspections, focusing on checking whether the roof is leaking, whether the wall is tilted, whether the drainage is smooth, whether hydrogeological disasters occur around, and the bridge should pay special attention to water level changes;
2. Strengthen early warning and prevention, pay attention to the prompt sheet and meteorological forecast of the Municipal Flood Control Headquarters in a timely manner, and timely do a good job in supporting and reinforcing emergency measures such as covering, and evacuating personnel;
3. Strengthen on-duty duty, keep in touch 24 hours a day, implement the "wake-up" mechanism, and implement personnel responsibilities;
Fourth, improve the emergency plan, strengthen emergency drills, according to the early warning level in a timely manner to do a good job of "five breaks and five passes" measures, timely issue a notice of temporary closure of museums, and promptly stop the construction of archaeological sites and cultural preservation project sites.
