Open the "green channel" for the protection of cultural relics
The Palace Museum in Beijing is a comprehensive Chinese museum, established on October 10, 1925, in the Forbidden City of the Forbidden City of the Forbidden City in Beijing, with collections including but not limited to the Imperial Palaces of the Ming dynasty and Qing Dynasty and their collections. The Palace Museum in Beijing is the largest museum of ancient culture and art in China and one of the three major palaces in the world.
In recent years, with the popularity of programs such as "National Treasures", "If National Treasures Can Talk", and "I Repair Cultural Relics in the Forbidden City", the Forbidden City and cultural relics have gradually entered the public's field of vision and become a popular topic, while making the restoration and protection of cultural relics the focus of public attention.
It is reported that the total number of existing collections of the Palace Museum in Beijing has reached more than 1.8 million pieces (sets), mainly including cultural relics of the Ming and Qing dynasties, ancient buildings and books. The collection is divided into 25 categories, of which the first-class collection is more than 8,000 pieces (sets), which can be called a treasure house of art*.
With such a wide variety and a large number, it is not easy to scientifically and rationally restore and protect the cultural relics in the Palace Museum in Beijing. How to ensure the smooth progress of cultural relics restoration work and ensure that cultural relics can be foolproof in the process of transportation and transfer is one of the important links in the proper management of cultural relics.
To this end, the Palace Museum in Beijing launched the underground warehouse renovation and underground connection channel project, aiming to provide protection for the cultural relics preserved in the underground cultural relics warehouse to be restored and studied, while reducing the potential damage caused by the environment to cultural relics.
Glorious mission, HDPE for cultural relics to support the "umbrella"
Due to the particularity of the Beijing Palace Museum and its collections, the underground passage waterproofing project of the Beijing Palace Museum has strict standards and requirements for waterproof design, material performance, construction safety and other aspects. The project not only requires "no leakage" and grade I waterproofing, but also to truly ensure the safety of historical and cultural treasures for a long time.
After comprehensive consideration and layer screening from the aspects of environmental protection, integrity, product quality, etc., the Oriental Yuhong HDPE pre-paved anti-stick waterproofing system has been unanimously recognized by the experts of the project team and has become a small "guardian" of the waterproof project of the underground passage of the Palace Museum, helping the construction of the 1st floor of the underground passage and the construction of the local 2-story waterproof project, and escorting the "customs clearance" of each precious cultural relics in and out of the warehouse.
Beijing Palace Museum underground passage 1 floor, local 2 layer waterproof project using Oriental Yuhong special polymer self-adhesive film waterproofing membrane, and combined with supporting auxiliary materials, professional tools. During the construction process, the main waterproof material HDPE polymer self-adhesive film waterproofing membrane is pre-laid on the base layer, and then the steel bar is tied on the surface of the membrane and the structural concrete is poured, so that the post-poured concrete is closely combined with the membrane, and the main body of the building forms a "full sticky" effect.
The waterproof membrane with high-density polyethylene (HDPE) as the bottom film, single-sided covered polymer self-adhesive layer, and coated with anti-stick weathering layer combination composition, with high strength, high extension deformation, water resistance, corrosion resistance, bacteria resistance and other excellent performance, green environmental protection, does not contain harmful chemicals, effectively eliminate the underground passage potential leakage and other safety hazards, in line with the strict requirements of cultural relics protection of the environment.
Standardized construction to escort the safety of cultural relics
In line with the cautious attitude of being responsible for cultural relics and history, the professional team of Oriental Yuhong HDPE strictly controls every detail, carefully organizes and standardizes management from material entry, construction preparation, grassroots treatment to coil paving, self-inspection and collection, and protection of finished products of waterproof layer.
Considering the open water and humid environment inside the underground passage of the Palace Museum in Beijing, as well as the high requirements of the project for the horizontal cushion base surface, the professional team of Oriental Yuhong HDPE took drainage measures, repaired the cracking gap and honeycomb of the base surface, and refined the preparation of the base surface.
At the same time, the construction adopts Oriental Yuhong HDPE self-produced special auxiliary materials with special tools, full-ring welding, and at the broken point of the coil, the T-shaped lap, the apex of the yin and yang angle, the supporting special auxiliary material cover strip is repaired or enhanced.
At present, the waterproofing project construction of the underground passage project of the Palace Museum is in full swing. Oriental Yuhong HDPE pre-paving anti-stick waterproof system excellent product quality, strict standardized construction, systematic service throughout the whole life cycle of the project to meet the palace museum underground passage project "structural inner wall dripping water, green environmental protection and no pollution" construction requirements. While being unanimously recognized by the various management departments of the Palace Museum, it has also accumulated valuable construction experience in the field of cultural relics protection and construction.
The Palace Museum is a treasure in the world cultural heritage and bears the social responsibility of inheriting and carrying forward the excellent traditional Chinese culture. Dongfang Yuhong is willing to take the original mission of "creating a lasting and safe environment for mankind and society" to protect the safety of cultural relics.
