The first is the principle of main construction deployment
1) Expand the working face: implement the overall strategy of installation engineering, first air duct, then water pipe and then electrical construction steps, and strive to ensure that the roof is installed first, so as to expand the working face and avoid cross construction in local scope as far as possible; At the same time, in view of the short construction period of the project, it is necessary to increase the staffing and carry out relevant work in different areas at the same time.
2) Strive to concentrate: for the same place, strive to concentrate for a period of time to put the equipment in place.
3) First up then down: for the same installation space and area, first install the equipment and pipelines with higher position, and then install the equipment and pipelines with lower position.
4) First inside then outside: for the same place, first install the equipment and pipelines inside, and then install the equipment and pipelines outside.
5) First main then auxiliary: in the same place or system, the main equipment and main pipeline are installed first, and the smaller equipment and branch pipeline are installed later.
6) First large then small: in the same construction section, the larger and heavier equipment and installation parts are installed first, and the smaller and lighter equipment and parts are installed later.
Next is the selection of construction sequence
1) The installation sequence of each specialty on the ceiling is to install the air pipe first, then the water and gas pipe, and finally the electrical engineering.
2) In the three-dimensional space installation, first install the larger part of the ceiling, then install the smaller part, and finally install the part in the room.
3) In the plane space installation, the principle of "from inside to outside" is adopted. Firstly, the equipment and main pipelines in the technical corridor are installed, and then the parts outside the technical corridor are installed; First install the inside part of the room, and then install the outside part of the room.
4) Organize and cooperate with the construction, intersperse the operation, rush the construction of key parts, and concentrate the superior forces to fight the war of annihilation.
Finally, other deployment measures
1) Promote advanced construction methods and construction machines and tools, improve the level of mechanized operation: in the installation and construction operation, a large number of electric and hydraulic tools should be used, the air duct processing and manufacturing should use mechanical processing, and the vertical hoisting should use mechanical hoisting as far as possible, so as to improve the level of mechanical operation and work efficiency.
2) The daily work meeting system is implemented. The manpower, material resources, machines and tools required by each specialty and each type of work are proposed in the meeting. The project manager uniformly arranges the coordination work between each specialty and each type of work, solves the remaining problems in the work of that day, and arranges the work of the next day.
3) Each professional technician can solve the problems on site at any time, and coordinate the cross work between different specialties.
Kaifeng DEAR air separation industry Co., Ltd. is a major equipment manufacturer and gas supplier in China's air separation industry. So far, DEAR air separation has produced more than 300 sets of large and medium-sized air separation units for domestic and foreign customers. DEAR Industrial Park is the first to build an intelligent air separation demonstration enterprise integrating intelligent production workshop, intelligent management and operation, and remote equipment monitoring. DEAR air separation has been focusing on the manufacturing and service of large-scale air separation equipment and cryogenic air separation for nearly 20 years. It has rich project engineering experience, and constantly uses innovative technologies to optimize equipment energy saving and safety, so as to bring higher benefits to customers.
The company has a number of patented technologies, of which two ultra-low pressure discharge energy-saving patents are domestic leading level, which can reduce the energy consumption of air separation plant by 5% - 15% and save operating costs.
The remote intelligent monitoring system independently developed by DEAR enables the whole process intelligent management of equipment field and remote monitoring terminal, early detection and early warning of faults, and saves the labor cost of field operators.
DEAR air separation has invested a lot to build an intelligent production workshop to ensure that the product quality is close to zero defects, improve the accuracy of air separation equipment and shorten the scheduled cycle.
