The construction of Changzhou Rail Transit Line 1 phase 1 pipeline rehabilitation and road repair project is composed of road structure construction, rain and sewage, power supply, information, water supply and gas pipeline construction. The construction site including tourism school station, Changzhou north station, Beijiao secondary station, Longhu station, the Yellow River Road station, the new park station.
In order to guarantee the quality of construction projects, from construction preparation stage to strict quality management, the specific contents are as follows: starting from 1, personnel organization level, dispatched elite staff to establish quality management team, perfect quality management system, clear personnel division and establish post responsibility; 2, starting from the technical level, field staff reading familiar with the construction drawings and relevant technical data, completes the construction plan, determine the quality control and detection scheme, construction technical clarification etc..
In the process of construction, the project department should grasp the quality control of the construction process. According to the construction characteristics of this project, the key process nodes are set as the quality control points, and the quality control of the control nodes is applied to ensure the quality control of the construction process. For example, in road construction, the main structure of the 6% soil foundation pit backfill construction quality has great influence on the quality of road construction project, through the development of programs and technical disclosure, for each layer of construction dust ash dosage, compactness, smoothness and edge angle are provided to detect artificial ramming and acceptance of the relevant requirements, not the standard of construction dust shall enter the next layer; for example, the pipeline construction projects include a new pipeline recovery, and migration, pipeline backfill requirements of road structure area because of pipeline, pipeline pipes with different at different depth, pipes have many different backfill materials used, including sand, gravel, concrete, soil, the soil content, the situation is more complex, the backfill quality requirements, the project department to collect related construction drawings, construction drawings collected all kinds of The pipeline backfill scheme is summed up, and sent to the construction team and specially for the on-site construction personnel. At the same time, the quality control of pipeline backfill construction is guaranteed, and the quality of pipeline construction is further guaranteed. In the process of construction in the future, we will continue to strictly control the quality of the project to ensure the successful completion of the construction task. |
