【摘要】：隨著我國(guó)城市化進(jìn)程的推進(jìn)，雨水控制利用系統(tǒng)有效的改善了城市發(fā)展過程中的排水負(fù)荷過大、水浸等現(xiàn)象，在特定情況下更可以將雨水充分資源化，，緩解用水壓力。因此，雨水控制利用系統(tǒng)在我國(guó)發(fā)展迅速。但由于現(xiàn)行規(guī)范的針對(duì)性較弱，使得雨水控制利用系統(tǒng)的設(shè)計(jì)存在一些問題。 本文針對(duì)在雨水控制利用系統(tǒng)設(shè)計(jì)過程中的設(shè)計(jì)參數(shù)展開了以下研究： 由雨水設(shè)計(jì)流量計(jì)算公式，提出雨水控制利用系統(tǒng)的設(shè)計(jì)參數(shù)，包括雨水控制利用系統(tǒng)的設(shè)計(jì)徑流系數(shù)、設(shè)計(jì)重現(xiàn)期以及蓄水池的容積三部分。 通過分析徑流系數(shù)的影響因素，提出開發(fā)建設(shè)前、后紅線內(nèi)（包括紅線外可能的）場(chǎng)地下墊面的徑流系數(shù)確定方法，提出適用于廣州市建設(shè)工程雨水控制利用系統(tǒng)設(shè)計(jì)的徑流系數(shù)計(jì)算方法。 通過對(duì)屋面雨水斗排水能力的計(jì)算，推導(dǎo)出廣州市屋面排水系統(tǒng)一定設(shè)計(jì)重現(xiàn)期下雨水斗可負(fù)荷的最大重現(xiàn)期。介紹了采用擬合法對(duì)廣州市降水頻數(shù)曲線進(jìn)行擬合，以推算廣州市年最大日降水量的重現(xiàn)期的方法。采用查表法推算出廣州市年最大日降水量值，為選擇雨水控制利用系統(tǒng)的設(shè)計(jì)重現(xiàn)期提供參考。 根據(jù)廣州市相關(guān)要求，參考北京市相關(guān)規(guī)定，提出廣州市不同情況下的建設(shè)工程中雨水控制利用系統(tǒng)蓄水池容積的確定方法及實(shí)施建議。通過計(jì)算不同重現(xiàn)期下蓄水池的容積及不同材料蓄水池的成本，為雨水控制利用系統(tǒng)設(shè)計(jì)參數(shù)的選用提供參考。
[Abstract]:With the development of urbanization in our country, Rain Water has effectively improved the phenomenon of excessive drainage load and flooding in the process of urban development by controlling and utilizing the system. Therefore, under certain circumstances, Rain Water can be fully used as a resource to relieve the pressure of water use. Rain Water's control and utilization system is developing rapidly in our country, but due to the weak pertinence of the current standard, there are some problems in the design of the system. In this paper, the design parameters in the design process of Rain Water control and utilization system are studied as follows:. Based on Rain Water's design of flow calculation formula, the design parameters of Rain Water control and utilization system are put forward, which include three parts: the design runoff coefficient, the design recurrence period and the volume of the reservoir. Based on the analysis of the influencing factors of runoff coefficient, the method of determining the runoff coefficient of underground cushion surface in the red line (including possibly outside the red line) before the development and construction is put forward. The calculation method of runoff coefficient suitable for Rain Water control and utilization system design of Guangzhou construction project is put forward. Based on the calculation of drainage capacity of roof Rain Water bucket, the maximum recurrence period of rain bucket load in Guangzhou roof drainage system is deduced. The fitting method is used to fit the frequency curve of precipitation in Guangzhou. By using the method of calculating the recurrence period of the maximum annual precipitation in Guangzhou, the maximum daily precipitation value of Guangzhou city is calculated by using the method of look-up table, which provides a reference for selecting the design recurrence period of Rain Water control and utilization system. According to the relevant requirements of Guangzhou, referring to the relevant provisions of Beijing, This paper puts forward the method of determining the volume of the reservoir of Rain Water control and utilization system in different construction projects in Guangzhou, and puts forward some suggestions for its implementation. By calculating the volume of the reservoir and the cost of the reservoir with different materials, the volume of the reservoir under different recurrence periods and the cost of different materials are calculated. It provides a reference for the selection of design parameters of Rain Water control and utilization system.
