At the same time, the designer will replace all indoor solid walls with movable partitions, so that the space can be used for flood discharge at the first time even in case of rainstorm and flood
.
Q: Henan rainstorm has become a major event in the country, and the flood caused by Rainstorm over the years is an important topic for buildings
.
Can you put forward some professional suggestions on flood control during construction? Yu Ting: there are two kinds of flood control in cities
.
Near the river is a high flood area, and the potential flood depth of the site is recorded as 1.17 meters
.
In addition to using artificial materials to raise the house, in Estonia, b210 architects used local birch trunk to raise the building to avoid flood damage# MaidlaNatureVilla The white birch tree of the ladder forest cabin raises the whole building to a height of 1m above the ground, and the 7m long screws are screwed into the soft soil
.
At the same time, the window opening part at the junction of the roof and the facade wall is changed into a floor type rotating metal window to ensure the entry of sunlight and natural wind without damaging the local architectural customs
.
While fighting the flood, the building retains the elements of local architectural culture and integrates the surrounding environment with modern design language
.
One is the flood control of ordinary buildings, and the other is the flood control of large-scale municipal facilities
.
The reconstruction of niederhafen levee in Hamburg reconnects its riverside corridor with the surrounding urban texture and establishes a connection with the surrounding communities
.
It is meaningful to talk about this matter separately
.
Integration of flood control facilities into urban space # Niederhafen riverside corridor, Hamburg Zaha Hadid architecture firm, a 625M long riverside corridor located in niederhafen on the Elbe River in Hamburg, is an important part of the optimization and reinforcement of urban flood control system in Hamburg, Germany
In sunny days, the bottom of the house can be used as a temporary parking lot
.
By adding steel structure at the bottom of the house, the architect raised the house to 2.2 meters from the ground to make the house “step on stilts”
.
The first is the timely prediction and early warning processing
.
While being used by architects, “horizontal roof” is still a frequent place for drainage problems
.
Therefore, the compressive strength of the house is large, which is conducive to avoiding impact in flood
.
The flood control of large-scale municipal facilities, including culverts, subways and even the basement in shopping malls, belongs to the prevention and control of ordinary citizens
.
The designer inverts the original roof from the regular triangular roof to the inverted triangular roof to expand the shelter area of the house and facilitate the drainage of the roof
.
It does not need to tilt the roof, because the excess water will be lost by seepage rather than discharge, and will not cause additional load on the building structure
.
Whether it is to raise buildings above the flood water level, design under the architectural style of respecting local customs and lifestyles, or build with flood resistant materials and environmental protection materials, and use coatings and veneers to prevent water from entering the house, it is worth learning from
.
What should be provided is an auxiliary equipment, that is, auxiliary flood control measures and mechanical measures, which is very key
.
Whether it is large-scale facilities, municipal facilities or facilities built by ordinary citizens, the greatest requirement is to ensure the safety of power supply without problems.
.
At the same time, the power system used by the building is an environmentally friendly solar power generation system and a prepared biogas power generation system, which can not only prevent flood, but also achieve energy conservation and environmental protection
.
In order to better match the limited land, the house was cut into irregular shapes“ We are trying to create a space to remind people of their connection with nature, its vulnerability and value – it has disappeared in many places
.
Flood is a major problem faced by buildings around the world
.
Except for embankment roads, all roads are often below the water level
.
Nishizawa architects carries out effective waterproof and flood control design on the basis of combining local architectural culture
.
In 2006, Hamburg organized a design competition for the reconstruction of flood embankment, and finally Zaha Hadid architecture firm won the design right of the project
.
Whether it is to raise the building above the flood water level, or to prevent it with waterproof materials or coatings, how to use building auxiliary prevention and control measures to resist flood tide disasters under rainstorm? suit one’s measures to local conditions # Nishizawa, Judu house, Vietnam Due to the humid and hot climate in Vietnam, the rainy season lasts for 4 to 5 months every year
.
On the premise of conforming to the local regional spirit, build a building combined with the surrounding environment
.
Raise the foundation and reduce the hydrodynamic pressure # Narala house, UK The architect designed John Pardey’s Narula house, which is located on the Bank of a tributary of the Thames River in England
.
” Because of the raised setting, you can row a canoe directly from the terrace to a safe area even at high tide
.
Plant vegetation on the roof to reduce water permeability # New roof waterproof scheme BrasilArquitetura office Architects from Brasil arquitetura, Brazil, proposed a solution to enrich flat roofs with vegetation
.
The east section of the linear structure is 8.60m high and the west section is 8.90m high, which can protect the city from winter storm surges and extreme waves
.
Therefore, most traditional buildings are mainly of the dry diaphragm type with wide cornices and multiple windows
.
Deco also specially connected three architects: Yu Ting of wutopialab, Guo Donghai of Dahai Xiaoyan design, and Chen Xiawei of the youth creation center of the General Academy of landscape architecture of Chinese Academy of fine arts to talk about their views on waterproof and flood resistant buildings
.
In fact, the flood control of large facilities depends on two points
.
Henan rainstorm affects the attention of the whole country, and the flood caused by rainstorm is an important issue faced by buildings
.
After reconstruction, niederhafen flood dike in Hamburg integrates the city’s famous riverside corridor, which is located on the top of the flood dike, which can not only enjoy the port scenery at a glance, but also realize the function of flood fighting
.
In case of sudden flood, Narula house can be “suspended” on the river, reducing the “hydrodynamic pressure of coastal flood”
.
The use of traditional sloping roofs and tiles for drainage is a traditional method
.
By continuously pouring water into the slab, the temperature change of the slab structure is reduced, the generation of cracks is reduced, and then the water permeability of the roof is reduced to realize “water-proof”“ This is a very simple and cheap system
.
Integrating flood control facilities into urban space and modernizing, upgrading and strengthening at the same time has become an indispensable part of urban construction
.
” Pouring integration, lifting and suspension # Stamp house, Australia Charles Wright architects, a water leaning concrete building with a bold shape, is located on the edge of the tropical rain forest in Australia’s National Park
.
The integrated lifting design of the house allows the building to avoid floods and withstand strong airflow
.
The design does not hide flood control measures, but further uses the height advantage to interweave the landscape and architectural form, and introduce the natural landscape into the indoor space
.
In order to avoid the potential threat of water level rise caused by climate change, the architect John Pardey raised the residential foundation as a whole so that water can flow freely through the bottom of the building
.
The whole building is raised by local stone or concrete columns, and the frame is floating timber frames wrapped with corrugated metal sheets
.
The whole building is completed by the combination of concrete prefabrication and on-site pouring
.
