【摘要】：隨著城市化進(jìn)程加快,城市內(nèi)澇問題越來越突出。為解決因下墊面硬化引起的城市內(nèi)澇問題,探求建設(shè)項(xiàng)目中雨水池容積計(jì)算方法。本文以北京市房地產(chǎn)建設(shè)項(xiàng)目為研究對象,從北京市1953—2012年降雨數(shù)據(jù)中選取降雨量最大、平均和最小年的日降雨數(shù)據(jù),并擬定中水同時(shí)用于綠化和道路澆灑,應(yīng)用日水量平衡模型方法,對比分析雨水池可利用率和中水補(bǔ)給率變化趨勢,綜合考慮經(jīng)濟(jì)效益因素,確定雨水池適宜容積。應(yīng)用多項(xiàng)式擬合法,得到雨水池適宜容積簡易計(jì)算模型。結(jié)果表明:隨著雨水池容積增加,雨水池可利用率增大(0~1),中水補(bǔ)給率減小(1~0);當(dāng)雨水池容積增至一定程度,其可利用率與中水補(bǔ)給率的變化趨于平緩;3種年況的雨水池可利用率的關(guān)系為最大平均最小,中水補(bǔ)給率的關(guān)系為最大平均最小,為互補(bǔ)趨勢;效益費(fèi)用比隨著雨水池容積增大而減小。經(jīng)驗(yàn)證,模型符合工程建設(shè)要求,且具普遍性,可投入應(yīng)用。為提高模型可靠性,應(yīng)用時(shí)宜將模型計(jì)算結(jié)果與規(guī)范最低建設(shè)標(biāo)準(zhǔn)進(jìn)行校核比對。本研究為今后雨水池設(shè)計(jì)提供了一種新的快捷簡便算法,豐富了設(shè)計(jì)理論。
[Abstract]:With the acceleration of urbanization, the problem of urban waterlogging is becoming more and more prominent. In order to solve the problem of urban waterlogging caused by the hardening of the underlying surface, the method of calculating the volume of rain pool in the construction project is explored. In this paper, the real estate construction project in Beijing is taken as the research object. From the rainfall data of Beijing from 1953 to 2012, the daily rainfall data of the largest, average and smallest years were selected, and the reclaimed water was developed for both greening and road sprinkling, and the daily water balance model method was applied. By comparing and analyzing the changing trend of utilization ratio and recharge rate of reclaimed water in rain pool, considering the factors of economic benefit, the appropriate volume of rain pool is determined, and the polynomial fitting method is used. A simple model for calculating the suitable volume of rain pool is obtained. The results show that with the increase of the volume of rain pool, the utilization ratio of rain pool increases by 0 ~ (1) ~ 1 ~ (-1), and the recharge rate of middle water decreases by 1 ~ (10) ~ 0 ~ (th), and the volume of rain pool increases to a certain extent. The relation between the availability of recharge and the recharge rate of reclaimed water tends to be the maximum average and the minimum, and the relationship between the recharge rate of recharge and the recharge rate of reclaimed water is the maximum average and the complementary trend. The ratio of benefit to cost decreases with the increase of the volume of rain pool. It is proved that the model conforms to the requirements of engineering construction, is universal and can be applied to improve the reliability of the model. This study provides a new quick and simple algorithm for rain pool design in the future, and enriches the design theory.
