Impressions of Nantong No. 2 Building
October in golden autumn, the autumn breeze is refreshing. On October 17, 2020, the Nantong branch of the group company organized all project leaders in the area to the Nantong Second Construction Building to observe and learn.
At 9 o'clock in the morning, all the observers entered the second building project one after another and entered the construction site. The overall feeling was that it was atmospheric, refreshing, and the overall plan was orderly. There should be a lot, and there should not be much, and it is concise and clear.
At 9:30 in the morning, I listened to and watched the PPT report of the second construction in the office of the second construction site in Nantong, and then all the staff went to the construction site for field visits and learning. Through the half-day observation and study, I have learned a lot and I am really impressed. I share my observation experience with everyone and learn and improve together.
Main highlights:
1. Drawing deepening and optimization: The whole construction process adopts three-dimensional reporting and BIM technology in advance to deepen and optimize the drawings in advance;
2. Construction organization and graphic planning: the real-name access (fast face recognition) of the second building from the entrance, tea pavilion, VP safety experience area, road layout, woodworking plant, steel bar processing site, garbage pool, construction elevator selection The layout of the model, tower crane, etc., drainage ditches, etc. are all formed at one time; the construction elevator adopts its own board platform (no need to set up a connecting platform). The outer frame uses a climbing frame instead of a traditional floor frame.
3. Implementation of innovative and excellent technology for main structure construction:
1. Design and construction technology for retaining excavated slope of deep foundation pit
2. Construction technology of tower crane foundation using piled raft foundation
3. The construction technology of the post-pouring zone after the temperature is outlawed
4, GRC cement board instead of foundation brick tire mold construction technology
5. New technology of post-casting with mould support
6. Optimized design of basement guide wall
7. Construction method for crack control of ultra-thick concrete floor
8. Application technology of high-efficiency concrete anti-crack, waterproof and durable admixture for basement clear water wall
10. Shear wall seamless butt construction technology
11. Construction technology for basement formwork without opening holes
12. Construction technology of square steel formwork system
13. Construction technology of frame column square steel hoop
14. Construction technology of double column channel steel reinforcement for deformation joints
15. One-time construction technology of main building and basement height increase
16. Construction technology of stairwell shear wall with primary support and secondary pouring
17. Staggered tool support technology for upper and lower floors
18. The construction technology of clean water shear wall without painting
Does not contain the above examples and other new processes and new methods
Fourth, the implementation of innovative and excellent technology for mechanical and electrical installation and construction:
1. Construction method of embedded wire box on concrete wall
2. Replace temporary firefighting with permanent firefighting
3. Permanent lighting of the heart replaces temporary lighting
4. The permanent drainage system was activated in advance to replace the temporary pumping of the basement
5. Assembled construction technology of HDPE drain pipe in bathroom
6. Pre-branch cable installation technology
7. Deepening technology for integrated pipeline shared support
5. The establishment of safety and civilized standards for smart construction sites
Visit the Erjian Dashu project, it does not feel like a construction site, especially the construction site office is like entering a Suzhou courtyard, and the meeting room is like a business meeting room. The site is clean and tidy. All facilities are stereotyped, processed and assembled. The steel bar work sheds are all movable. The real-name channel at the door is a fast facility. The warehouse shelves and goods yard are neatly stacked. The woodworking sheds are specially equipped to prepare ingredients. Computer-controlled feeding is used. The elevator is a frequency conversion elevator, and there is no external frame with its own flap type elevator. All border enclosures are finalized, especially the elevator entrance layer adopts hard isolation, and uses embedded casing to arrange hard isolation, which is efficient, fast and convenient. Wait for too many examples,
VI. Electronic 3D model display
The on-site construction model adopts 3D display, so that all personnel can directly face it, and understand the construction technology and methods from multiple angles and levels.
Seven, green three-star buildings to create humane and environmental protection
During the whole observation process, we did not find any bare soil in one place. It was covered with lawn blankets. The waste formwork was cleaned and washed. The waste template was specially processed to protect the corners. The basement uses LED lights. The whole project is environmentally friendly and energy-saving.
8. Positioning Luban Project
The start of the project is clearly positioned and the target is the Luban Prize. We looked at the concrete structure. The ground is as smooth as it has been done. The column surface is smooth. All external and internal corners are distinct. There is no obvious expansion. The leaking grout has clear edges and corners. Polished, giving people a refreshing feeling.
Through the half-day observation, we have learned a lot, but also felt a lot. On the surface, we are doing very well. There are many bright spots in terms of safety, civilization, quality, green, and environmental protection. But from the in-depth analysis, as long as the highlight lies in the preliminary planning and construction organization. For example, the second building adopts climbing frame construction. They have kept up with the exterior wall construction before the climbing frame climbs, and adopted the paint-free technology to solve the problem of the future climbing frame removal. The bottleneck of construction. According to the characteristics of the project, use new processes and technologies as much as possible to save costs and improve work efficiency. Strengthen team building and boldly use newcomers. According to observations, the average age of their project team is 36 years old. Of course, what you see is only the surface, and the inner essence can only be experienced and thought by yourself. Only in this way can it be applied in today's project management, improve management capabilities, and improve project quality. (Gu Yuntao)
