Originated from 丨Southwest Company of China Construction Eighth Bureau
Recently, the western part of the mainland
The first case of "air pillow" foundation pit air film in
Sichuan Provincial People's Hospital of Southwest Company of China Construction Eighth Bureau
Comprehensive Research Building Project
Successfully applied
Perfect for the dust-proof sky
A green "dome" was erected for the construction site of the project
New process + new material
Environmentally friendly, safe and efficient
The foundation pit air film used in the project
It is currently the western part of the mainland
It is applied for the first time in the construction of foundation pit in construction sites
Double-layer "air pillow" inflatable membrane
It is dustproof, noise-reducing, and energy-saving
A new green construction process that is fireproof and intelligent
The total area covered by the air film of the project is about 1,200 square meters
The maximum span is up to 44 meters and the height is 6 meters
The membrane material is strong, durable and fire-resistant
PVDF is a new building material that is resistant to high temperature and ultraviolet rays
It is recognized as following brick, stone, and concrete
The "Sixth Building Material" after Metal and Wood
The traditional "gas-bearing" foundation pit air film is adopted
The operation mode of single-layer film cloth + internal working space filling
Dust and noise reduction in confined spaces
"Air pillow type" foundation pit air film is adopted
The operation mode of double-layer film cloth + film cloth middle pressure
In the upper part of the foundation pit to form a hollow structure "roof"
Dust and noise reduction in the coverage area
It has stronger safety and stability performance
Thermal insulation effect, dust reduction and noise reduction effect
Compared with the traditional air film, it is also significantly improved
During installation
In order to ensure the safety and stability of the membrane
The project is covered with high-strength steel cables on the outside of the air film
The force on the membrane surface is transmitted, which can greatly reduce the stress of the membrane
In sudden extreme cases
The membrane can be dropped onto a mesh cable
Eliminate the risk of membrane collapse from the source
In terms of installation efficiency
The air film foundation anchor adopts the angle steel connection method
The lifting force of the air film can be evenly distributed to the ground beam
The film can be installed and dismantled as quickly as possible
The entire installation process took only 48 hours
Intelligent control + flood lighting
Smart, stable and comfortable
In order to ensure the smooth operation of the air film
The project adopts a fully intelligent control system of PLC
Making Air Dome Operations Smarter
Its overall control system includes a modular control system
Indoor and outdoor environmental monitoring system, pressure control system
Ventilation circulation system, backup energy system, etc
The difference in air pressure between indoor and outdoor air is measured according to the sensor
indoor and outdoor temperature and wind speed, etc
weather conditions and other factors
The system can be on the inside of the air film in time
Air pressure, temperature, humidity, etc. are monitored and fine-tuned
Allow the air film to operate at a reasonable pressure
Reduce energy consumption and improve operational efficiency
At the same time, it is also equipped with an emergency backup system as standard
In the event of a power outage or power failure
The intelligent control will automatically switch the backup generator
Ensure the continuous and stable operation of the air film
In addition to intelligent adjustment of air pressure, temperature, humidity and so on
The lighting of the foundation pit is also quite particular
The in-membrane illumination system is used:
State-of-the-art flood lighting
The high reflectivity of the film to light can be effectively utilized
For the interior of the building
Even, undazzling illumination
At the same time, it also achieves the purpose of saving energy consumption
Foundation pit air film + dustproof canopy
Dust and noise reduction and health
At the same time as the air film application
The project is also equipped with a traditional "dust canopy"
"Double insurance" for the green construction of the project
The dust-proof canopy system used in the project
The area is about 5,640 square meters
Equivalent to the size of 13 standard basketball courts
The canopy fabric is durable, flame retardant and recyclable
Customized green net, the implementation of unit layout
It consists of 6 dust filter units
The maximum unit is 41 meters long
The canopy system is controlled by mobile app and remote control
Two control modes
The switching time is 30 seconds
When there is a need for construction
An intelligent traction control system is available
Open the canopy in sub-units
Achieve an effective balance between environmental protection and operational efficiency
It is used through a combination of air film and canopy
The dust reduction rate at the project site has reached more than 90%.
It basically isolates the construction dust from the doctor-patient environment
The noise reduction rate is up to 60%, which is greatly reduced
The impact of construction noise on the interference of doctors and patients
At the same time, in the spray, ventilation and
with the lighting system
The air film canopy is also for construction workers
It has set up a comfortable working area with constant temperature and humidity
Ensure that the operator is protected from wind and rain, high temperature, etc
Adverse weather effects
It greatly protects the occupational health of workers
Sichuan Provincial People's Hospital
Comprehensive Research Building Project
The total construction area of the project is 106589 square meters
The total construction period is 1278 calendar days
It is expected to be completed by the end of 2026
The highest height of the project is 99.9 meters
The main functions are underground garages and equipment rooms
Department of Radiation Oncology, Surgical Area, Laboratory Department
Pathology, ICU, etc
When completed, it will be the largest surgical center in the western region
For the broad masses of the people
More first-class and efficient medical services
The project started in September 2023
During the construction process, the project team always adhered to it
High-standard planning, high-quality and efficient implementation
Refining has formed a "new and new, quality and prosperous".
"New quality" culture
Insist on thinking for innovation and improve ability and quality
Highlight the characteristics of the project with technological innovation
Strengthen the quality of performance with management innovation
The project has been conquered
Relocation of complex pipelines in hospitals without stopping
Deep foundation pit trestle slab - internal support construction and other technical difficulties
Successfully completed the relocation of the underground pipeline within 60 days
