【摘要】：随着城市化和工业化进程的不断深入,用水量正在逐步加大,一方面加大自来水厂的建设以满足城镇用水规模,另一方面工业废水和生活污水的排放也成为了城市发展需要解决的重要问题。由于生活污水和工业废水排放量的增加,污水收集管网和污水处理厂的建设相对滞后,造成了严重的水资源污染。根据天津市的总体安排,为了保障天津市经济持续健康发展,对排放污水进行集中处理。在净水厂和污水处理厂的建设中,水工建筑物的施工质量是净水厂和污水厂运行的基础保障,而在大型水工建筑物的施工过程中,伸缩缝的施工又是一个相对薄弱的环节。在近几年的净水厂和污水处理厂的建设过程中,由于伸缩缝施工质量问题造成的池体漏水事件时有发生。本文首先阐述了对伸缩缝质量问题的研究背景及意义、研究思路和方法。对目前水工建筑物伸缩缝从设计和施工角度的质量控制进行分析,找出目前还存在的质量问题。然后,从水工建筑物伸缩缝基于建设流程的质量影响因素进行分析。从设计阶段开始对影响伸缩缝质量的因素进行分析,施工阶段从质量问题影响的五大因素:人的影响因素、材料的影响因素、设备的影响因素、施工方法的影响因素、环境的影响因素,五个方面进行分析找出质量控制点。最后,结合某污水处理厂的工程实例,将理论研究应用到实践项目中,对生化池伸缩缝的施工进行质量控制改进,提高了水工建筑物伸缩缝的质量。
[Abstract]:With the deepening of urbanization and industrialization, water consumption is gradually increasing. On the one hand, the construction of water plants is increased to meet the scale of urban water use. On the other hand, the discharge of industrial wastewater and domestic sewage has become an important problem to be solved in the development of the city. Due to the increase of the discharge of domestic sewage and industrial wastewater, the construction of sewerage network and sewage treatment plant is lagging behind. According to the overall arrangement of Tianjin Municipality, in order to ensure the sustainable and healthy development of Tianjin's economy, centralized treatment of sewage is carried out. In the construction of water purification plant and sewage treatment plant, The construction quality of hydraulic structures is the basic guarantee for the operation of water purification plants and sewage plants, but in the construction process of large hydraulic structures, The construction of expansion joints is also a relatively weak link. In recent years, during the construction of water purification plants and sewage treatment plants, The leakage events of pool body occur from time to time due to the construction quality problems of expansion joints. This paper first describes the background and significance of the research on the quality problems of expansion joints. This paper analyzes the design and construction quality control of the expansion joints of hydraulic structures, and finds out the existing quality problems. This paper analyzes the factors affecting the quality of expansion joints of hydraulic structures based on the construction process. From the design stage, the factors affecting the quality of expansion joints are analyzed. In the construction stage, there are five major factors that affect the quality of expansion joints: human factors. The influencing factors of material, equipment, construction method, environment and five aspects are analyzed to find out the quality control points. Finally, combined with the engineering example of a sewage treatment plant, Applying the theoretical research to the practical project, the quality control of the expansion joint of the biochemical pool is improved, and the quality of the expansion joint of the hydraulic structure is improved.
