▲ the “giant sky curtain” system device in the semi open state is designed with a labor-saving opening and closing device guided by double pulleys, which reduces the opening and closing stroke of the curtain and improves the overall safety and reliability.
▲ the giant “sky curtain” completely covers the foundation pit ▲ under the “sky curtain” and can enjoy the shade.
at this stage, area a is carrying out the construction of four underground floors and the demolition of the fourth support.
To this end, the first company of China Construction Eighth Bureau and Hangzhou Ecological Environment Bureau jointly explore the application of the “sky curtain” system.

Recently, in the core urban area of Hangzhou, a “giant sky curtain” appeared over the foundation pit of the construction site of Hangzhou Henglong square project undertaken by the first company of China Construction Eighth Bureau, realizing the closed management of the whole foundation pit excavation site, changing “open-air operation” into “indoor operation”, effectively reducing on-site dust and construction noise, and becoming the first “sky curtain” system implemented in Zhejiang Province, It has attracted the attention of mainstream media such as Zhejiang Daily and Hangzhou Daily.
It is expected to complete the positive and negative zero structure in October 2022; The third supporting earthwork excavation is under way in area C, and the bottom slab pouring is expected to be completed in November 2022.
The overall plan of the project will be completed in March 2025.
At present, there are three foundation pits in area C of the project.
At the same time, it has the functions of shading, noise reduction and light pollution prevention, so as to ensure that all environmental protection indicators in the stages of basement construction and foundation treatment meet the requirements and reduce the impact on the surrounding environment.

▲ effect drawing of Hangzhou Henglong Plaza Project Hangzhou Henglong Plaza project is located in baijingfang plot in Wulin business district, the most prosperous core business district in Hangzhou, with a straight-line distance of only 500 meters from the West Lake.
Hangzhou Henglong Plaza project is divided into two construction areas: Area A and area C.
▲ effect drawing of “sky curtain system” ▲ before the “giant sky curtain” is opened, in order to ensure the full coverage of the foundation pit cavity area, the total length of the project “sky curtain” system is 150m, the span is about 35m, and the total coverage area is 5000 m2.
The T2 office building is 150 meters high, which is the highest building along the West Lake scenic spot.
Metaphorically, “it’s like a horizontally placed electric curtain.” In addition to achieving the covering effect, the system is also being upgraded to build a smart construction site, including five aspects: closed noise reduction system, sky curtain dust reduction system, 5g non road mobile machinery AI identification and monitoring system, green environmental protection vehicle management system and pilot implementation of new energy concrete transport vehicles, which will achieve all-round dust and noise reduction.
▲ the “sky curtain” device close to the residential living area on the construction site is a dust prevention and control device that can realize remote control and fully cover the construction site in the air.
The three-layer earthwork excavation stage is under way.
A large amount of earthwork needs to be transported outside every day, which is very easy to cause dust and noise pollution to the surrounding areas.
The total construction area of Hangzhou Henglong Plaza project is about 390000 square meters, including a world-class shopping mall, five class A office buildings and a high-end hotel.
It is suitable for the design and installation of long-span sky curtain devices.
