河道整治治理措施
Regulation measures for river regulation
1. 山溪性河道治理
1. mountain river regulation
(1)灘地的保留和利用
(1) preservation and utilization of beach land
灘地是山溪性河道的特有產物。一般河道灘地較開闊,洪水期水流漫灘,利于行洪滯洪,應保留其功能,并充分開發利用。流經城區的河道,在維持灘地行洪功能的同時,利用灘地設置綠化地、公園、交通輔道和運動場所,開發其休閑、親水功能,成為市民娛樂、健身、游玩的好地方。整治中,順應河勢,因河制宜,保留河灘和彎道,恢復河道的天然形態,減少河床的坡降,降低洪水位,減少洪峰壓力,同時可降低防洪堤的高度。另外,彎曲的水流更有利于生物多樣性,為各種牛物創造了適宜的生存環境。
The beach is a unique product of mountain stream. Generally, the beaches of rivers are relatively open, and the flood season is full of water, which is beneficial to flood detention and flood discharge, so its functions should be retained and fully exploited. The river course flowing through the city maintains the flood discharge function of the beach, and at the same time, the beach is used to set up green land, parks, traffic auxiliary roads and sports places, so as to develop its recreational and hydrophilic functions, thus becoming a good place for citizens to entertain, keep fit and play. In the course of regulation, we should conform to the river regime, keep the beaches and bends, restore the natural form of the river, reduce the slope of the river bed, reduce the flood level, reduce the peak pressure and reduce the height of the flood dike. In addition, the curved flow is more conducive to biodiversity, creating a suitable living environment for all kinds of cattle.
(2)復式斷面的設計
(2) design of compound section
山溪性河道一般河灘開闊,河道斷面設計可采用復式斷面形式??菟诹髁啃?,水流歸槽主河道;洪水期流量大,允許洪水漫灘,過水斷面大,洪水位低,一般不需修建高大的防洪堤??菟诟鶕訛┑膶挾群偷匦?、地勢,結合當地實際充分開發河灘的功能:如灘地較寬闊,一般可開發高爾夫球場、足球場等大型或綜合運動場;河灘相對較窄的可修建小型野外活動場所、河濱公園或輔助道路等。河灘的合理開發利用,既能充分發揮河灘的功能,又不因圍灘而抬高洪水位,加重兩岸的防洪壓力。
Mountain river channels are generally open, and cross section can be used for river section design. In dry season, the discharge is small, and the water flows to the main channel; in flood season, the discharge is large, flood floods are allowed to overflow, cross-section is large, flood level is low, so there is no need to build high dike. In dry season, according to the width, topography and topography of the beach, the function of the beach can be fully exploited according to the local conditions: if the beach is wide, the golf course, football field and other large-scale or comprehensive stadiums can be developed; the beach can be relatively narrow and small-scale field activities can be built, riverside parks or auxiliary roads. Reasonable development and utilization of river beach can give full play to the function of river beach, without raising flood level due to beach enclosure, and aggravate flood control pressure on both sides.
