摘 要

雨水收集和利用并非是新鲜事,我国早在秦汉时期就有修建池塘拦蓄雨水用于生活的

记录,而西北地区水窖的修筑已有几百年的历史。国外收集利用雨水的记录也不乏其例。而真正现代意义的雨水收集利用尤其是城市雨水的收集利用是从20世纪80年代到90年代20年时间里发展起来的。随着城市化的进一步加速,城市缺水的矛盾进一步加深,环境与生态问题也同步发展。为了解决缺水、环境、生态等一连串的矛盾,人们把注意力放到雨水的收集和利用。这一课题正好是解决了缺水、环境、生态着一连串的问题。国外对这一课题的研究起步较早,国内城市收集利用雨水起步较早的首都北京,而上海尽管水的质量不好但并不缺水。然而雨水的收集和利用解决的并不仅仅是水的问题,它还可以减轻诸如上海地区日显巨大的自来水的供水压力、路面积水等问题。对水土流失、河水污染等问题也有一定的缓解作用。

高架桥如今在大中型城市中非常常见,桥下一般设有绿化带,但是由于高架桥桥面的阻挡,下雨的时候,雨水经常无法淋到下面的绿化带,这使得相关管理部门不得不安排一定的人力资源来浇灌绿化带。桥面上的雨水经排水管网,也直接流入下水管道,如果能把桥面上雨水收集起来,并用于桥下的绿化带浇灌,将可以减少很大一部分人力和财力。同时也可以减轻城市绿化用水的压力,高架桥雨水的收集利用作为城市雨水收集利用的一部分,对城市的可持续发展有着重要意义。

高架桥雨水收集及自动浇灌系统可以总的分成两个部分,一个是雨水收集系统,如何有效的收集桥面上的雨水并储存,是我们首先要解决的问题,现有排水管道与雨水收集系统的结合利用对随见成本有很大的帮助。二是自动浇灌系统,浇灌系统需要解决的是雨水的增压,定时自动控制和管网的布置。 关键词:高架桥,雨水收集,蓄水箱,喷灌

Abstract

Rainwater collection and utilization is nothing new, our country early in Qin and Han dynasties have built ponds retain rainwater for life records, while the northwest water cellar construction already had history of hundreds of years. Foreign collection of rainwater utilization in recording and that is the example of. But the real significance of modern rainwater collection and utilization especially city collected rainwater utilization is from the nineteen eighties to 90 time 20 years developed. With the further acceleration of city, city is short of water contradiction further, environmental and ecological problems are synchronous development. In order to solve the water shortage, ecological environment, such as a series of contradiction, people focus on the rainwater collection and utilization. This problem is solved, the ecological environment water, a series of problems. Foreign research on this topic starts earlier, the collection of city rainwater utilization started earlier in the capital of Beijing, and Shanghai, although the water quality is not good but not water. However, rainwater collection and use to solve the problem is not just water, it can also reduce the area such as Shanghai is huge water pressure, surface water problems. On Soil and water loss, water pollution has some relief.

The viaduct is now very common in large and medium-sized city, under the bridge are generally equipped with a green belt, but due to the elevated bridge of the barrier, when it rains, the rain often cannot be caught in the green belt below, this makes the relevant management department to arrange a certain amount of human resources to irrigate green belt. Deck water by the drainage pipe network, also directly into the sewer, if the deck rainwater collected under the bridge, and for the green belt to irrigate, can reduce a large part of human and financial resources. At the same time can also relieve the city virescence water pressure, elevated bridge rain collection and utilization of rainwater collection and utilization as a part of the city, the city 's sustainable development is of great significance.

Overpass rainwater collection and automatic irrigation system can be generally divided into two parts, one is a rainwater collection system, how to effectively collect and store the rainwater on the bridge, is that we must first solve the problem, the existing drainage and rainwater collection system using combined with see cost has a great help. Two is the automatic watering system, irrigation system is to solve the water pressure, timing and automatic control of pipe network layout.

Key words: viaduct, rainwater collection, storage tank, spray irrigation.
