Huizhou Fire Seal Walls in Chinese Traditional Buildings
Edit
This entry is adapted from the peer-reviewed paper 10.3390/fire6100388

In the history of human civilization, traditional villages and buildings have been significantly threatened by fire. As an essential part of Huizhou traditional architecture, fire seal walls play a crucial role in preserving Huizhou architecture by effectively blocking the spread of fire.

1. Fire Prevention in Traditional Chinese Buildings

China has a long history and rich cultural heritage as one of the four ancient civilizations. Traditional villages and buildings have been widely distributed throughout the country as cultural heritage objects with significant regional and ethnic characteristics [1], which not only have historical research value [2] but also contribute to the inheritance of traditional culture [3], improvement in infrastructure [4], and development of agriculture and tourism [5][6]. As stated by the Chinese Ministry of Housing and Urban-Rural Development, 8171 villages were included in the List of Traditional Villages of China by the end of 2022 [7], which rendered China the most significant cultural heritage conservation country worldwide [8]. However, with recent economic and social advancements, China has experienced frequent fires, which pose a severe threat to the conservation of traditional villages and buildings, and many traditional villages and buildings are destroyed by fire every year [9]. For example, a fire broke out in the ancient city of Dukesong in Yunnan Province, China, in 2014, covering an area of nearly one hundred and one acres, causing the destruction of 242 old buildings and direct property damage amounting to 89.83 million yuan. A fire broke out in an ancient town in Nanjiang County, Sichuan Province, China, in 2016, causing 26 people to be affected and property damage totaling more than 3 million. This entails not only historical and cultural heritage loss but also significant damage to the local natural environment and human landscape. There are four main reasons for fires. First, traditional Chinese buildings are mainly constructed of wooden structures, which have been eroded by wind and rain for thousands of years and exhibit a low water content; thus, they can easily ignite once they encounter open fires [10]. Second, traditional Chinese villages and buildings are mainly located in remote rural areas, which usually have treacherous terrain and roads, making it difficult for fire engines to enter and extinguish fires [11]. Third, traditional Chinese villages are densely distributed with small building spacing, which promotes the occurrence of mass fires. Fourth, firefighting facilities in rural areas must be improved, and public awareness of firefighting must be enhanced. It is difficult to extinguish fires the first time they occur. Therefore, it is still a significant problem that fire threatens the conservation of traditional buildings and villages [12]. 

2. Fire Research in Traditional Buildings

Fire protection research for traditional villages and buildings is currently focused on the following four aspects: First, fire risk assessment research [13][14] mainly identifies potential or existing fire risks of target objects using field research and provides assessment levels using hierarchical analysis, fuzzy analysis, and accident tree analysis [15], and corresponding fire protection optimization strategies are finally proposed in a targeted manner. Secondly, numerical simulation research of fires [16][17][18] mainly adopts the FDS software (https://pages.nist.gov/fds-smv/downloads.html) simulation method to establish a traditional village or building numerical model so that it can be employed to study the changes in flame plume, smoke spread, and heat radiation conditions during a fire. This method dramatically reduces the cost of fire research and provides high experimental safety and economy. Thirdly, physical experimental combustion simulation research [19][20][21] entails the construction of a scaled or full-size model to study the combustion characteristics of wood and fire spread patterns between buildings. This measurement method is more accurate than numerical simulation, but the economic cost and danger are significantly higher. Fourthly, traditional fire protection technology research [22], which favors the theoretical level, focuses on compiling and summarizing ancient villages and building fire protection experiences using historical literature and field research and providing corresponding explanations. For example, Chinese patios and fire alleys are ancient fire prevention techniques that have saved countless houses from disasters for hundreds of years. From the above, current research on fire prevention in traditional villages and buildings is a focus of research from theoretical to practical levels, and it is conventional relative to present technology levels.
However, from microscopic combustion simulation to macroscopic fire risk assessment levels, research on traditional fire prevention technology remains at the theoretical research level, with few scholars verifying conventional fire protection measures using modern technology and proposing updated alternatives. Moreover, with the development of contemporary society, traditional fire protection systems are gradually disintegrating and disappearing, and the original fire protection measures can no longer fully meet the requirements of village or building protection; thus, it is essential to conduct a modern fire protection transformation of traditional fire protection technology.

3. Huizhou Fire Seal Walls

Huizhou fire seal walls are called Matou walls because the top base of the wall is shaped to resemble a horse’s head. Huizhou fire seal walls are usually made of brick and stone; they are built around wooden buildings and are mostly constructed with hollow bucket walls because they do not bear weight [23]. Therefore, the bricks in Huizhou are large and thin. The fire seal wall is built freely, roughly following the rule that the lower solid fence should be covered with air and the empty wall should not be connected; the wall is usually painted with white ash, and the eaves are covered with very small green tiles [24], forming a powder wall with tiles, which is very decorative. There are three main parts:
  • Wall;
  • Plucked leaves, pallets, and pallet heads, for which the primary function is to prevent the wall from being directly impacted and soaked by rain;
  • The ridge of the Matou wall is the closing part of the sealed firewall.
According to the number of eaves on the wall above the roof, they can be classified as fire seal walls with a single eave, fire seal walls with triple eaves, and fire seal walls with quintuple eaves [25] (Table 1). Huizhou fire seal walls, primarily located in the Huizhou region of China, are a traditional Chinese building fire protection technique that can effectively prevent flames from spreading to adjacent buildings in the event of a fire, thus reducing the danger. Most existing Huizhou fire seal walls originated during the Ming and Qing Dynasties, when He San, the governor of Huizhou, ordered residents to adjust the height of walls for fire protection, after which fire seal walls were widely used for fire protection in the Huizhou area. For hundreds of years, they have been used as essential fire protection technology to protect Huizhou’s traditional villages and buildings from the threat of fire and safeguard the lives and property of countless people.

However, with the development of modern society, the fire protection function of the Huizhou fire seal wall has gradually weakened, and the original fire protection system and architectural style have been seriously damaged; thus, traditional Huizhou fire seal walls can no longer meet modern fire protection demands.
From the above, the fire prevention situation of traditional Chinese buildings and villages is becoming increasingly serious, and traditional fire prevention technology is gradually dying out. As a traditional fire prevention technology, Huizhou fire seal walls have very important fire prevention research value, but there is little research in related fields. Therefore, it is necessary to further strengthen the role of traditional fire protection technology for traditional village and building conservation. Inspired by this aspect, this study established the following research steps: First, traditional villages in Huizhou were visited, conducted field research on the Huizhou fire seal wall of the traditional Chinese fire protection system, and selected a typical dwelling for mapping. Secondly, the Huizhou fire seal wall was numerically simulated using FDS software (https://pages.nist.gov/fds-smv/downloads.html). The purpose was to compare fire resistance differences and the weak points of fire seal walls with single eaves, triple eaves, and quintuple eaves under the same conditions and analyze the effects of wind speeds, building spacing, and vertical ridge height on the fire resistance of Huizhou fire seal walls under different fire scenarios. Finally, corresponding Huizhou fire seal wall renovation strategies were proposed, which provide a practical reference for the future fire protection renovation of the same type of fire seal walls, and this fundamentally contributes to the protection of traditional villages and buildings in Huizhou.
