Hangzhou national edition Library (Hangzhou branch of China national edition Library) is a carrier bearing the imprint of Chinese civilization at all times and in all countries. The Chinese version transmission project, which is based on the construction of the national version library, is a major cultural project deployed by the state from the perspective of cultural security and cultural rejuvenation strategy. It is an excellent transmission project that "continues the Chinese context, strengthens cultural confidence, displays the image of a big country, and promotes dialogue among civilizations". It has been listed in the proposal of the Central Committee for the 14th five year plan. The completion of this outstanding project marks the addition of a new era cultural landmark in Hangzhou.

The importance of this project is self-evident! The complexity of the design structure, the high difficulty of construction and the tight construction period of such an important and cultural heritage era architecture project can be seen. As the waterproofing contractor of the project, Luban waterproofing overcame various difficulties with its own specialty and strength, and completed the waterproofing construction of this high-quality project on time and with good quality. Today, Luban waterproofing will reveal to you how the waterproofing Part of this legendary boutique project is completed.

Overall aerial view of the building

Hangzhou national edition hall, also known as "Wen Run Pavilion", is designed around the "contemporary book collection architecture with the charm of gardens in the Song Dynasty", with a total construction area of 103100 square meters, including a total of 13 units, including the main study, the South study, Wen Run Pavilion, Mountain Warehouse and auxiliary rooms. Among them, the parts with higher waterproof difficulty are Hall 3, beichi, Mountain Warehouse and wenrunge.

Book collection, not a bit damp waterproof how to do?

Waterproof and revealing secrets: books are a kind of material that is very easy to absorb water. After the paper is soaked in water, it is very easy to rot and deteriorate, losing its use and collection value. Ordinary books need to pay special attention to waterproof and moisture-proof, not to mention handed down classic books. Therefore, as the main venue for book edition storage, hall 3 puts forward high requirements for waterproofing.

It has been proved that Luban craftsmen have done very well.

4000 square meters of water is stored all year round. How to waterproof a large pool?

Waterproofing: from the aerial view, we can see that the whole North pool has a huge area. Even from a high altitude, we can see this water body at a glance. It is a 4000 square meter pool built on the roof of the building, and it holds water all the year round. Waterproofing such a pool is a great test for the skills of Luban waterproof craftsmen.

In order to ensure no leakage, the team added Luban waterproof characteristic product cold scraped non curing rubber asphalt waterproof coating to the original design. The product has the characteristics of no heating, good viscosity and simple construction. It is convenient for construction even in cold winter, greatly shortening the construction period and providing guarantee for the timely completion of the project.

Two mountains in one, how to do the waterproof of the stepped tea mountain?

Waterproofing: the mountain warehouse is located in the east of wenrunge, a dilapidated mine and an ecological tea mountain. The combination of the two mountains not only completes the restoration of the mountain, but also makes the mountain full of vitality. This stepped tea mountain has complex structure and numerous nodes. It is also a difficult waterproof challenge. However, only with challenges can we have the opportunity to surpass ourselves. Meet the challenge with strength, just like Luban spirit.

Overlooking the mountain

According to the characteristics of the mountain, the waterproof materials here mainly use two layers of polyurethane film waterproof and root puncture resistant waterproof coiled materials, and cooperate with the water storage and drainage board. To ensure the quality of the project with the idea of both prevention and elimination.

Wood returns to nature, but what about waterproofing of wood structure?

Water proofing: there is a natural closeness between people and wood. When wood is used in architecture, there is a design concept of returning to nature. Natural wood is also widely used in the design of Hangzhou national edition Museum. Wenrun Pavilion is located on the east side of the mountain. The architectural design is mainly wood structure.

Wen Runge

As the main structural material of wood architecture, the degree of dryness and wetness of wood directly affects the safety and durability of architecture. It is not difficult for the wood structure to be waterproof, but to ensure the long-term use effect, it is also a test of the construction method and skill level for waterproof craftsmen. The waterproof material here mainly uses butyl rubber waterproof coiled material.

The above is an introduction to the waterproofing of the main difficult projects. The whole project has a long duration, heavy tasks and complex waterproofing work, which can not be expressed in a few short paragraphs. The opening of the Hangzhou national edition museum will be held soon (July 30). Before clocking in the landmark buildings of this era, understanding the waterproof details behind these buildings and visiting them with these "stories behind" may enable us to experience more the beauty and greatness of this song rhyme building, as well as the efforts and difficulties of all the builders behind it. Let's pay tribute to the fine products and waterproof people!
