What are the specific contents of the construction organization design of a heating pipe network in Zhengzhou City? Zhongda Consulting will answer it for you below.
1. Project Overview
This project is the first bid section of a cogeneration central heating pipe network project of a thermal power plant, including: Huanghe East Road (crossing the North-South Canal), D426×8 260 meters of hot water pipes; 300 meters of D630×8 hot water pipes on Huanghe East Road (crossing the Qili River); 660 meters of D600 hot water pipes on Future Avenue (Shenzhuang North Road-Jinshui East Road). This project is supporting municipal roads Engineering thermal sub-item. The design pressure of the pipeline is 1.6Mpa, the supply and return water temperature is 130/65°C, the water supply pipe is laid directly buried with compensation, and the return water pipe is laid directly buried free of charge. The pipe connection method is welding.
Preparation basis:
1. Design drawings and other design documents of a heating pipe network designed by a thermal engineering design institute in Zhengzhou City.
2. "Technical Regulations for Urban Direct Buried Heating Pipeline Engineering" (CJJ/T81-98)
3. "Code for Design of Urban Thermal Pipeline Network Engineering" (CJJ34-2002)
4. "Code for Construction and Acceptance of Urban Heating Pipe Network Projects" (CJJ28-89)

6. "Code for Construction and Acceptance of Industrial Pipeline Engineering" (GBJ235-97)
7. "Code for Construction and Acceptance of Industrial Pipeline Welding Project of Field Equipment" (GBJ50236-98 )
8. "Steel Weld Radiographs and Film Classification Method" (GB3323)
9. "Construction and Acceptance Specifications for Industrial Equipment and Pipeline Insulation Engineering" (GBJ50264-97)
10. "Industrial Equipment and Pipeline Insulation Engineering Pipeline and Equipment Insulation Quality Inspection and Assessment Standards" (GB50: 85-93)
II. Construction Deployment
According to the work content stipulated in the bidding documents, based on the characteristics and specific circumstances of this project with tight construction period and heavy tasks, and taking into account the principle of scientific and reasonable arrangement and close collaboration of civil engineering and installation. The overall layout is as follows:
1. Make full preparations before the start of construction, organize construction personnel and machinery to enter the site in a timely manner according to the plan, arrange construction water and electricity, and arrange living facilities for construction personnel. Organize the arrival of engineering materials in a timely manner to prepare for the official start of construction.
2. From the day the project starts, order materials.
3. Pipe trench excavation and main pipeline laying are in full swing. At this stage, the formal construction peak has entered. Project department managers at all levels and in various professions must strengthen project construction management, organization and command, construction site scheduling and technology, quality and safety management, as well as cross-construction cooperation and coordination between civil engineering and installation majors. work to ensure smooth and normal construction.
4. In order to ensure the construction period, according to the characteristics of civil engineering and installation majors with many cross-construction operations at the same time, dynamic management of personnel and machinery should be adopted to ensure the deployment of personnel and machinery at any time. It is necessary to ensure that personnel, machines and tools, and working surfaces are not idle to ensure that the construction period goals are achieved.
