The construction of sponge cities is on the way

Abstract

“ Sponge cities” construction was proposed at NPC and CPPCC. This is the social environment hotspot in recent years, which has a very important influence on our future life. As the first 3D printing architecture enterprise, Winsun adheres to the mission of “ make sky bluer, water cleaner, mountain greener and the world more beautiful” to build sponge city by promoting 3D printing sewage well, septic tank.

What is sponge city? "Sponge city" is a new generation of urban rain flood management concept, which is refers to the city in adapt to environmental changes and respond to natural disasters brought about by the rain has good "flexibility", also called "elastic water city".

“ Sponge city and NPC and CPPCC

“ Sponge city and NPC and CPPCC

On March 5, 2017, at fifth session of the twelfth National People's Congress of the People's Republic of China, Premier Li proposed that we will coordinate the construction of underground underground construction in cities, and start construction of the urban underground comprehensive pipe gallery more than 2000 kilometers, and start the three years of operation to eliminate the key areas of the urban area, and promote the construction of sponge cities. 

“ Sponge city” international style

Paris: The drainage system is well known around the world.

Paris is one of the most complex urban drainage system in the world, after 126 years to build a successful before and after the drainage system is currently total length of 2347 kilometers, far beyond the scale of the subway system. With developed drainage systems, Paris can cope with the deluge. Due to its reasonable design, clean and beautiful and large scale, the drainage system in Paris enjoys a worldwide reputation. It has become a representative landscape, with more than 100,000 people visiting and studying every year.

Roma: Sewers have a long history.

2,500 years after the sewers were built, modern Rome is still in use. Around the 6th century B.C., the idararians used a canal system built by rocks to drain the flood from the city of Rome. The largest section of the channel system is 3.3 meters by 4 meters, from the ancient Roman city square to the Tiber river. In 33 AD, when Rome's construction officer cleaned the sewers, he traveled through the sewers in a row of boats to see how spacious the sewers were.

Berlin: The integrated system drain contamination

There are two kinds of sewage pipes in Berlin, namely, sewage rainwater confluence pipes and sewage stormwater diversion pipes. The goal of the whole drainage system is to prevent waterlogging in the city, save rainwater, use waste water rationally, and save water resources. In addition to the underground facilities, Berlin city builders use landscape drainage pressure off on the ground, will be part of the park into a rolling terrain and artificial wetland, and encourage community building rainwater landscape and artificial lake.

Winsun 3D printing drainage facilities

Urban drainage system is an engineering facility system to deal with urban sewage and rainwater, which is an important support of "sponge city". Most cities in China are not well equipped with drainage system, which leads to urban waterlogging, which not only pollutes the environment, but also brings a lot of inconvenience to urban residents. In order to support the construction of urban drainage system, Winsun has launched 3D printing sewage wells and 3D printing septic tanks and other drainage facilities.

Winsun 3D printing dual drain well

The traditional drainage construction scheme is mainly artificial: drainage pipe for measuring unreeling, earthwork excavation and basement, basal cushion counterpart, concrete, concrete pipe inspection Wells and 20 procedure, to build a long time, poor construction environment, the risk is high, the slope and the height of the sewage well difficult to control, leaking would happen.

Winsun 3D printing of sewage wells, only by the construction requirements, intelligent double-layer printing, automatically adjust the slope and height, to achieve 100% accuracy, to complete the water.

At present, such products have been used in Shandong Binzhou, Suzhou dayyangshan scenic spot, Zhejiang Jiaxing Youyou city south real estate project.
