    原標(biāo)題:故宮600年排水系統(tǒng)抵御暴雨襲擊

    7月31日拍攝的雨中故宮。

    連日,北京迎來強(qiáng)降雨天氣,故宮再現(xiàn)“九龍吐水”,依靠精妙的排水系統(tǒng),宏大的故宮建筑群,在暴雨中安然無恙。紫禁城的雨水排水系統(tǒng)始建于明代,故宮的地面順應(yīng)北京地理環(huán)境特點(diǎn),整體走勢(shì)呈北高南低、中間高兩邊低,而且略有坡度。這一坡降為自然排水創(chuàng)造了有利條件,使積水能緩慢排泄。故宮保留至今的古代雨水溝的長(zhǎng)度超過15公里,其中暗溝長(zhǎng)度將近13公里。故宮內(nèi)的排水溝渠全部通向內(nèi)金水河,內(nèi)金水河又與故宮城墻外側(cè)52米寬的護(hù)城河相連,并同周邊的外金水河、中南海等水系相通。
