Focus on new industries and build a "healthy China" together.
Recently, China Construction Installation undertook the construction
The Nanjing Medical Device Industrial Park project was successfully completed.
The project is located in Nanjing, Jiangsu Province.
The total construction area is about 63,000 square meters,
Nanjing company undertook the construction of 4 high-standard Class C plants,
1 general office building and other construction contents.
After the completion of the project, it will help build a collection of biomedical research and development,
Intelligent manufacturing, pharmaceutical logistics and other functions in one
international industrial parks,
To create a new highland for the development of medical device enterprises in Nanjing,
Inject new momentum into the extension and development of the medical industry.
Innovation empowers
Lean construction
The project is close to the Yangtze River,
It is a typical floodplain landform of the Yangtze River,
The foundation soil is mainly silt and fine sand, and the water level is shallow.
Seepage of surrounding surface and groundwater
It is very easy to cause the instability of the side wall of the deep foundation pit excavated by the project.
In the face of sudden dangers such as quicksand and pipe gushing in the pit,
The project adopts the "three-in-one" precipitation method in innovation——
"Tube well dewatering + new well point dewatering + rapid backfilling",
Efficient precipitation in the pit,
Effectively ensure the stability of the foundation pit,
Lay a solid foundation for the construction of the project.
The project adheres to scientific and technological innovation and planning first.
For deep foundation pits, high formwork,
Concrete pouring and other key processes,
Comprehensively establish a parametric model library,
Through the BIM model, the covering pile foundation,
Deep foundation pits, earthwork excavation, underground structures
and more than 100 plans for disclosure,
Precise layout of each component,
Ensure "zero risk" in the construction of underground structures.
At the same time, the project is innovatively used
The management mode of "BIM drone + smart construction site",
Introduction of intelligent management platform,
AI hummingbird box, drone cruise, etc.,
Deeply integrate advanced information technology with site management.
Security escort
Efficient construction
From the original "spread out" design,
To this day, "stacked up" to build,
The overall building of the project adopts a high and low collocation,
The combination of detached houses.
During the construction process,
The project adopts the "landing + cantilever" scaffolding scheme,
Successfully placed the flower basket type cantilever scaffolding
It is used in high-rise industrial plants,
Reducing the overall scaffolding load,
The impact of foundation settlement on scaffolding is avoided,
Escort the construction safety of the main structure of the project.
The main structure of the project is constructed as follows
"steel truss floor deck + cast-in-place beam" system,
For the requirements of special plants,
The project adopts the support system of "formwork-free + beam-plate integration".
In order to ensure the safety factor of high formwork,
The construction period of the complex building has been increased from 10 days/floor to 8 days/floor.
The construction period of the plant has been increased from 12 days/floor to 10 days/floor.
Construction efficiency has been greatly improved.
More than 300 builders worked at the same time, interspersed with advancement,
All processes are seamlessly connected,
Completed 56,000 square meters of earthwork excavation in 10 days,
Complete 10,000 square meters of concrete pouring in 3 days,
45 days to break through the basement full plus or minus zero,
100 days to break through the capping of all main structures,
Gain a head start on quality fulfillment.
Quality first
Built with ingenuity
As a high-standard, high-precision medical device workshop,
For the use of precision medical instruments such as optical microscopes
and biochemical tests have extremely high requirements for tightness.
During the construction process, the project adopts a seamless design of anti-micro-vibration.
By setting up the method of "expansion reinforcement belt + continuous pouring",
The continuous pouring of ultra-long structural concrete has been realized.
At the same time, the project implements the "24-hour duty system" when pouring.
Especially for key parts such as roofing
Implement a double duty system for management personnel,
Strict monitoring and fine control,
Realize seamless design + seamless construction of pouring,
Ensure the high-quality operation of medical devices and instruments in the later stage.
The project adheres to the bottom line of quality and pursues quality improvement.
Adhere to the model-first approach,
From virtual samples, process templates to physical samples,
all-round and full-coverage management,
Ensure that the whole process of quality management is controlled.
Held during construction
Nanjing Economic and Technological Development Zone promotes the high-quality development of the biomedical industry
and Medical Device Industrial Park Customer Meeting,
The construction of the project has been praised by all parties.
The project set up a study group,
Enhance team cohesion,
Insist on intensive learning and exchange of experience every day.
Review and sort out the work of the day in a timely manner;
The project manager is both a leader and a supervisor.
Through the learning mode of small podium and big teacher,
Tell the professional knowledge and transfer the skills and experience.
The certificate holding rate of the whole team reached 100%,
Promote the construction of the project with high standards and high quality.
