At the end of the year, all the survey work of the Jiangnan Changxing shipbuilding base has been completed, but because there is a shortage of construction period, the cofferdam project will have to wait until the dry period in the second half of next year.
However, the relevant design work of Jiangnan Changxing Shipbuilding Base has been carried out.
Of course, the most important thing is the design of Line 3.
It is important to know that Line 3 is a military production line in the planning, which is not only the core business of Jiangnan Changxing Shipbuilding Group, but also a key facility to support the future Chinese Navy to move towards an ocean-going navy.
At present, a Type 052B and a Type 052C destroyer built by Jiangnan Changxing Shipbuilding Group for the Chinese Navy in the old factory have been launched and are in the final outfitting process.
You must know that the Chinese Navy will need more Aegis ships in the future, and it has already been determined that the No. 3 line of the Changxing Shipbuilding Base in Jiangnan will be the main construction base of the main destroyers of the Chinese Navy in the future.
Therefore, in terms of the overall layout and design of Line 3, whether it is the leading group of CSSC Jiangnan Changxing Shipbuilding Base, or the design unit CSSC Ninth Institute, or Jiangnan Changxing Shipbuilding Group, they all attach great importance to it.
At the end of the year, the Ninth Institute of China Shipbuilding held a demonstration meeting on the design of the excavated port basin of Line 3.
It is important to know that although the Changxing shipbuilding base in the south of the Yangtze River has drawn a coastline of 10 kilometers, it is still insufficient, especially considering that the situation of building a large number of naval destroyers in the future may occur, and the base is located at the mouth of the Yangtze River, and the water current is relatively rapid, which still has a great impact on the stability of small and medium-sized ships when outfitting and berthing.
Therefore, Line 3 designed a huge digging harbor basin, connecting several indoor horizontal slipways, open-air horizontal slipways, docks and outfitting docks on the edge of the harbor pool, and more than ten outfitting docks were also designed on the edge of the harbor basin.
In this way, the number of outfitting docks has been greatly expanded, and the requirements for the simultaneous construction of large quantities of military ships have been met.
At the beginning of the demonstration meeting, Zhang Xinghua, chief engineer of the Ninth Institute of China Shipbuilding, the design unit, turned on the PTT projector and displayed a huge overall layout map in front of the participants.
Zhang Xinghua introduced: "Everyone, please see, this is our design plan, the total length of the berth of this harbor basin reaches 1,400 meters, the plane shape is octagonal, the design high water level is 4.5 meters, the low water level is 4 meters, the water area reaches more than 110,000 square meters, and a 250-meter-long and 50-meter-wide lock is set up between the harbor basin and the south port, so that the water level of the excavated harbor basin is not affected by the tide of the Yangtze River, and the harbor basin does not need to set up flood control facilities around the harbor pool, and the wharf around the harbor basin is not affected, and the cost can be greatly reduced.
Such an overall arrangement is not only the first of our institute, but also the world's first water-style project.
Leaders and experts, if there are deficiencies and mistakes, please criticize and correct. ” Jin Hanlin, leader of the project leading group and general manager of China Shipbuilding Industry Group, nodded: "Yes, this design fully reflects the characteristics of our CSSC. ” Shen Huan thought of the problems encountered by Luo Fei's foundation engineering company in the construction of the dock infrastructure, so he was the first to stand up and said: "Mr.
Jin, leaders, I would like to make a small suggestion.
The design of our No. 3 harbor basin is indeed to create a record of hydraulic engineering, like such a large area of foundation pit engineering, and in such complex geological conditions of construction, there must be huge construction risks in the construction process, so I think we can use the three-dimensional limited analysis, as well as construction simulation simulation numerical analysis, to analyze and study the various deformations during the excavation of the harbor foundation pit, so as to formulate effective control measures to ensure the smooth and safe completion of the project. ” Zhang Xinghua nodded and said: "Assistant Shen's suggestion is very good, our harbor project, the foundation pit area has reached 120,000 square meters, which is nearly twice as large as the largest No. 3 dock, according to the previous engineering experience, if the deformation of the excavation process is not strictly controlled, it is indeed easy to cause local instability, and then affect the consequences of the construction safety of the entire project."
We'll look into it, thank you!
” Ma Baoguo, assistant to the general manager of China Shipbuilding Industry Group and general manager of China Shipbuilding Changxing Construction and Development Co., Ltd., said: "Mr.
Zhang, your nine institutes should give full play to their leading role and realize the good interaction between engineering design and construction in the construction. ” Jin Hanlin said: "Mr.
Ma said well, our shipbuilding base construction has its particularity, divided into many types of projects, such as water engineering, land engineering, equipment installation engineering and some special projects, such as our harbor basin, the construction difficulty is also quite large, so this requires our Ninth Institute, our Changxing Construction Company, must cooperate well, in the process of project management, to configure enough experienced management personnel for on-site command and coordination." ” After a pause, Jin Hanlin said: "In particular, our Line 3 project, according to the overall plan, is required to be completed and put into use first, to quickly form production capacity, our navy is still waiting for our production line to build a new type of destroyer for them."
Therefore, everyone continued to speak freely and gave us more suggestions for the Ninth Hospital. ” …… After this demonstration meeting, the Ninth Academy received a lot of suggestions, which also fully played the role of the demonstration meeting, that is, to gather the opinions of experts from all walks of life and make the best plan.
The design of CSSC Jiangnan Changxing Shipbuilding Base is steadily advancing, and the New Year is coming soon.
In the past year, Shen Huan's harvest is really not small, not only wearing multiple hats, but also the continuous improvement and promotion of pulsating production line technology, the construction of Jiangnan Changxing Shipbuilding Base, and the work of the Technology Innovation Center.
Of course, Shen Huan knows that additive manufacturing technology is not as good as pulsating production line technology, it is a real high-precision technology, and it is too early to apply it to the shipbuilding industry.
In the additive manufacturing technology project, the most important thing is the introduction of talents, so it is definitely an important task to dig the high-quality students of Xi'an Jiaotong University to the technology innovation center.
Fortunately, next year, Huang Li will graduate with a doctorate, I believe she will not miss such a good opportunity of CSSC, Shen Huan is also looking forward to what this future additive manufacturing technology expert will do after coming to CSSC?
Nanjin Xinyu Electronics Co., Ltd. has now developed into a giant in the MP3 market, and now it is about to develop MP4 and mobile phones, and Shen Le has also grown into a management talent for R&D projects.
