Abstract: Изобретение относится к области дорожного строительства и, в частности, к устройствам ливневого водостока. При подготовке дорожного полотна к укладке по нему покрытия, по обочине, а при наличии бордюра то и под ним, устраивают подсыпку из песчано-гравийной смеси (ПГС), образуя вдоль дороги дренаж в виде траншеи, засыпанной ПГС. При установке дорожного бордюра, окаймляющего дорогу, одновременно укладывают продолговатые решетчатые ж/б элементы «доска», которые укладывают по ПГС, тем самым образуется дренажное устройство. Дорожные потоки скатываются по дорожному покрытию на обочины и через решетчатые элементы попадают в придорожный дренаж, по которому стекают по уклону, тем самым предотвращая затопление дорог. При отсутствии бордюра по обочинам дорог и улицам населенных пунктов вместо кюветов предусматривают придорожный дренаж, как и в случае с бордюром, и укладывают обрамляющие железобетонные решетчатые элементы. Для снижения интенсивности потоков устройство аккумулирующих ловушек выполняют с определенным шагом вдоль дорог в виде отсыпки из ПГС поперек дорожного покрытия на всю ширину, располагаемой в массиве дорожного основания, соответствующего объема засыпки из ПГС, на всю ширину дорожного полотна по длине 3-6 метров, глубиной около 2.0 м (по глубине промерзания при пучинистых грунтах в основании) с покрытием этой зоны решетчатыми железобетонными элементами. Изобретение позволяет снизить риск затопления дорог; загрязненные потоки воды с дорог, проходя через дренаж из ПГС, очищаются естественным образом и в реки попадают уже очищенные, а очищение самого дренажа также происходит естественным путем микробной флорой; дождевые потоки и талые воды, проходя по дренажу, интенсивно инфильтруются глубоко в почву. 4 ил.
