【摘要】：咸阳市的泾阳地区地下水中绝大部分为苦咸水,水质较差,地下水中溶解性总固体、总硬度、氟化物、硫酸盐等指标均不符合生活饮用水卫生标准,泾阳县及泾河新城居民长期饮用苦咸水与高氟水,这已严重影响居民的身体健康。张家山泉群位于泾阳县西北30km泾河出山口处,属地质断层和裂隙比较发育的地带,泉水密集,水质优良,储藏量大。为了解决泾阳地区居民生活用水问题,本着优水优用原则,当地政府决定实施张家山泉群饮水工程,引张家山优质泉水为民所用。咸阳市张家山泉群供水工程分为泉水收集及预处理工程、输水管道工程两部分。本文旨在研究、设计泉群泉水的收集、预处理、输送等内容,提出安全、合理、可靠、经济的设计方案,发挥工程效益。本文对以往张家山泉群水量的测量成果进行了分析,合理的确定的本次工程的收集规模为8万m3/d;针对不同性质、位置的上升泉、下降泉提出了不同的收集泉室方案;考虑到泉群所处水利文物保护区的条件限制,方案即满足工程要求又不影响水利风景文物的保护,泉室尽量做到现状地面以下,收集管道和现状人行栈道合理结合,建构筑物建筑风格满足风景区人文景观要求,做到了工程和古迹、自然、人文的和谐共处;方案还合理的利用了泾惠渠排沙漏斗等现状工程设施,将预处理构筑物有效地布置排沙漏斗上方,利用排沙漏斗作为清水池,达到了节省用地与工程投资的效果。
[Abstract]:Most of the groundwater in Jingyang area of Xianyang City is brackish water, and the water quality is poor. The total dissolved solids, total hardness, fluoride, sulfate and other indexes in the groundwater do not meet the sanitary standards of drinking water. The residents of Jingyang County and Jinghe New City have been drinking brackish water and high fluoride water for a long time, which has seriously affected the health of the residents. The Zhangjiashan Spring Group is located at the exit of the Jinghe River 30 km northwest of Jingyang County. It is a geological fault and fissure area with dense springs. In order to solve the problem of water consumption for residents in Jingyang area, the local government decided to implement the drinking water project of Zhangjia Mountain Spring Group in accordance with the principle of superior water use. The water supply project of Zhangjiashan Spring Group in Xianyang City is divided into two parts: spring water collection and pretreatment project and water pipeline project. The purpose of this paper is to study and design the collection, pretreatment and transportation of spring water. A safe, reasonable, reliable and economical design scheme is put forward to give full play to the project benefit. This paper analyzes the measurement results of the water quantity of Zhangjia mountain spring group in the past, and reasonably determines that the collection scale of this project is 80,000 m3 / d; according to the different properties, In view of the conditions of the water conservancy cultural relic reserve where the Quan Group is located, the scheme not only meets the engineering requirements but does not affect the protection of the water conservancy landscape and cultural relics. Spring room as far as possible to achieve the status of the ground below the collection of pipes and the status of pedestrian walkway reasonable combination of the building structure to meet the architectural style of scenic spots to meet the requirements of human landscape to achieve a harmonious coexistence of engineering and monuments nature and humanity; The scheme also makes use of the current engineering facilities such as the Jinghui channel sand discharge funnel reasonably. The pretreatment structure is effectively arranged above the sand discharge funnel and the sand discharge funnel is used as the clear water pool to achieve the effect of saving land use and project investment.
