In the first week of the new year, Harbin was an instant hit, and the cold city suddenly became the hottest topic.
Tourists from all over the world really feel what "ice and fire" is here, and the evaluation in Northeast dialect is three words - leverage!
However, there is no such thing as a feast that will not be dissolved. "The ice and snow world is about to melt in the spring breeze", "Ice and snow art has always been 'disappearing beauty'", "I look forward to meeting you again in Harbin when the lilacs are in full bloom and the next snowflakes are fluttering......".On the evening of February 13, Harbin Ice and Snow World issued a closure announcement (closed from 24 o'clock on February 15), saying goodbye to tourists and friends with very poetic words, which also means that Harbin's ice and snow fairy tales are about to come to an end.
Many netizens took the opportunity to ask: "How did the ice and snow landscapes that are all over the ice city and embody the painstaking efforts and wisdom of countless craftsmen come to an end?" Will it melt naturally or will it be violently dismantled? "In fact, the removal of ice and snow sculptures is also a technical job, and there is a big way, let's take a look.
The de-icing time is roughly fixed, but this time it was a bit early.
In recent years, the relevant reports on the demolition of ice and snow landscapes in Harbin are concentrated from the end of February to the beginning of March every year, which is directly related to the local climatic conditions in Harbin. However, compared with previous years, the local weather in Harbin warmed up earlier this year, so that the closure time of scenic spots such as Ice and Snow World and Songhua River Ice and Snow Carnival was earlier, and the time for dismantling the ice and snow landscape was also significantly earlier.
From the end of February to the beginning of March every year, it is the moment for Harbin people to say goodbye to the ice and snow world. At this time, above-zero temperatures have become the norm, and the closing time depends on the speed of snow and ice melting. In 2015, Snow World closed on March 2. In 2016, the closing time of Ice and Snow World was basically during this time period.
On the evening of February 27, 2022, Harbin Ice and Snow World was officially closed. On February 28 of the same year, a number of scenic spots on the Songhua River began to demolish ice and snow buildings to prevent the collapse from causing safety hazards.
The 2024 6th Harbin Songhuajiang Ice and Snow Carnival announced that the park will be closed at 21 o'clock on February 12, and the demolition will be carried out in an orderly manner from the 13th, and the demolition will be completed before February 24. From February 13th, all amusement projects in the Kanto Ice and Snow Park will be stopped, and all businesses will immediately and orderly carry out the withdrawal of amusement facilities.
It's not a rush to the top, and the ones with potential safety hazards are dismantled first.
On February 13, 2024, the highest temperature in Harbin reached minus 5 degrees, and many tourists were concerned about "how the snow sculptures are doing". The Sun Island Snow Expo revealed that more than 80% of the snow sculptures in the Snow Expo park can still be viewed, and the integrity is maintained at more than 90%. In order to ensure the safety of visitors and the best experience, on February 13, some small snow sculptures were dismantled, and large snow sculptures were stopped for daily restoration.
As the temperature rises, some small, finely carved snow sculptures with cutouts have become structurally unstable or even collapsed. For the safety of visitors, the dismantling of such snow sculptures will be carried out today. Fan Jingrui, project leader of the engineering department of the Sun Island Snow Expo, said that as the temperature rises, honeycomb-shaped weathering points gradually appear on the surface of the snow sculptures. At present, the scenic spot is stepping up the structural assessment of the snow sculptures every day, enclosing individual snow sculptures with structural problems, and shoveling out the dangerous parts of the unstable structure.
On February 13th, the "beauty" work on the snow sculptures, which had been going on since the opening of the park, was also stopped. "After the surface of the large snow sculpture forms a honeycomb and weathers, the snow on the surface is twenty or thirty centimeters in a state of crushing as soon as it is scratched. Li Zhipeng, a snow sculpture restorer, said that his work has changed from restoration to demolition.
Ice sculptures dig "wall feet", and snow sculptures scrape "ice cream".
The demolition of ice and snow landscapes and buildings is a sloppy "delicate job", and ensuring safety is the top priority. The entire demolition process of Harbin Ice and Snow World lasted about 20 days, and the demolition of each ice scene had to be strictly calculated.
Recently, the excavator has opened up the ice and snow landscape, which has attracted widespread attention. Picture from: @极光新闻.
For example, tall ice sculptures need to be demolished with a hook machine (excavator) first, a large ice scene, after the best position and rolling direction, use the iron arm of the hook machine to dismantle the lower part of the ice scene first. As the lower half was hollowed out, with the accompanying "click" cracking sound, a huge ice landscape crashed to the ground. To dismantle a snow sculpture, the snow is scraped off layer by layer with a large machine, similar to using a giant ice shovel to scrape ice cream.
According to reports, the larger the snow sculpture, the more difficult it is to dismantle, and it is necessary to use a hook machine to dismantle it little by little.
The mini excavator goes up the snow slope, first dismantling the light line and then the ice.
After announcing the closure of the Ice and Snow World, it began to deal with all kinds of ice buildings, mainly using manual and machine (forklift bulldozers) to knock down and destroy large ice sculptures (ice buildings). When dismantling, follow the principle of "dismantling the lights first and then removing the ice".
The mini excavator drove up the big slide to dismantle the snow slope.
A winter ice carnival was held, with numerous light strips and wires set up inside the ice and snow walls. After all the recreational facilities were removed, the crew needed to dismantle the wires, light strips, and then the snow and ice buildings. The light strip and cable should be dug out first, as well as wooden sticks and wires, which should be pulled out and pulled away by car after bagging.
or melt naturally in situ, or centralize and unify treatment.
What should be done with the fragments of snow and ice sculptures after they have been dismantled? According to public reports, there are also differences in the handling methods.
Naturally melt in situ. Taking Ice and Snow World as an example, excavators and other machinery are used to break large ice sculptures into small pieces, mix them with small ice sculptures, and wait for them to melt. After the ice is melted, all kinds of residues are manually cleaned up.

Put it in the lake or in the forest. The remnants of snow sculptures left after the demolition of Nanhu Park in Changchun City will be arranged to be discharged into the lake or dragged into the forest.
Shipped to the designated place for processing. After the ice sculpture and snow sculpture are dismantled, forklifts, cranes, and dump trucks are used together to transport the residual ice and snow to the designated treatment point, flatten, and wait for natural melting, and then transport the remnants such as broken lamps to the garbage dump for burial.
