【摘要】：排水管网作为城镇的基础设施,与人们的生活息息相关,它对城镇的发展有着重要影响。在城镇的开发建设中,随着老城区的扩建和转型以及新区的开发和建设,城镇人口的增加,伴随着污水排放量的快速增大,排水管网的规划设计就显得尤为重要。本研究以陕西南部山区小城镇污水管网的设计为例,以优化污水管网系统规划设计,提高排水效率为目标,对污水管网系统从设计到建设进行了综合分析,从而为相关工程设计提供参考。本工程实例在设计中,充分利用现状地形高差,合理布置污水管道,除局部过河采用泵站提升外,其余污水管道均采用重力流,提升泵站采用传统泵站,泵站检修孔等采用法兰井盖,管道过河采用双管过河保证安全;管道截流采用了堰流式截流井,通过调节水位控制污水管道的流量;管道敷设时大部分采用直埋、局部采用架空形式,架空管道检查井和支墩一起浇筑,支墩上设有爬梯方便检修;提升泵站出水管敷设时每隔120m左右设置有压力检查井,管道沿线还设有排气井和泄水井。目前,污水管网已经全面施工。从当前实施的效果看,污水管网逐步建设实施后,污水收集的效率大幅度提高,直接排入汉江的污水明显减少,从而改善了所在镇域水体环境,污水管网收集系统作用已逐渐显现。这不仅对当地人居生态环境、生活质量和下游城镇生态环境有着积极的作用,同时对社会的可持续发展具有十分重要的意义。
[Abstract]:The drainage pipe network, as the infrastructure of the town, is closely related to people's life, and it has an important influence on the development of the town. In the development and construction of the town, with the expansion and transformation of the old urban area and the development and construction of the new district, With the increase of urban population and the rapid increase of sewage discharge, the planning and design of drainage pipe network is particularly important. This study takes the design of sewage pipe network in small towns in the southern mountainous area of Shaanxi as an example to optimize the planning and design of sewage pipe network system. In order to improve drainage efficiency, a comprehensive analysis of sewerage pipe network system from design to construction is carried out, thus providing reference for related engineering design. In the design of this project, we can make full use of the difference in topographic height of the present situation and arrange the sewer pipe reasonably. In addition to the local use of pumping station lifting, the other sewage pipes are used gravity flow, lifting pump station using traditional pump station, pump station maintenance hole using flange well cover, pipeline crossing using double pipe river to ensure safety; The pipeline closure adopts Weir flow closure well to control the discharge of sewer pipe by regulating the water level, and most of the pipelines are directly buried, while the partial aerial form is adopted. The overhead pipeline inspection wells and the piers are poured together. The piers are equipped with climbing ladders to facilitate maintenance, pressure check wells are set up every 120 m or so when the water pipes are laid in the lifting pumping stations, and exhaust wells and drain wells are also installed along the pipeline. At present, the sewage pipe network has been fully constructed. Judging from the effect of the current implementation, After the construction and implementation of the sewage pipe network, the efficiency of sewage collection has been greatly improved, and the sewage discharged directly into the Hanjiang River has been significantly reduced, thus improving the water environment of the town in which it is located. The function of sewerage network collection system has gradually appeared, which not only plays a positive role in the local ecological environment, quality of life and ecological environment of the downstream towns, but also has a very important significance for the sustainable development of the society.
