Description
Изобретение относитс к гидротехнике и может быть использовано дл реконструкции действующих гидросооружений при повышении нормального подпорного уровн в верхнем бьефе. Известен способ увеличени высоты пролетного строени затвора, заключающийс в полной замене существующего затвора на новый 1 . Недостатками этого способа вл ютс высока стоимость, материалоемкость и трудоемкость . Известен также способ увеличени высоты пролетного строени затвора на действующих гидросооружени х, включающий наращивание дополнительных секций пролетного строени 2. Недостатками известного способа вл етс больша стоимость и металлоемкость, вследствие необходимости усилени конструкции всего существующего пролетного строени на воздействие дополнительной гидростатической нагрузки. Целью изобретени вл етс снижение трудоемкости работ. Цель достигаетс тем, что наращивание дополнительных секций пролетного строени производитс с его нижней кромки. На чертеже изображен затвор, продольный- разрез . Затвор состоит из пролетного строени 1, основных опорных щарниров 2, дополнительной секции 3 пролетного строени щарниров 4 дополнительной секции, расположенных на ногах 5 пролетного строени 1. Способ осуществл етс следующим образом . Приподнимают пролетное строение 1, затем производ т наращивание дополнительной секции 3 с нижней кромки Пролетного строени 1. После этого присоедин ют дополнительную секцию 3 к ногам 5 пролетного строени при помощи щарниров 4. Дополнительна секци 3 рассчитываетс на гидростатическую нагрузку в соответствии с новым повыщенным уровнем верхнего бьефа. Существующее же пролетное строение остаетс неизменным, поскольку гидростатическа нагрузка на него остаетс прежней. Использование изобретени позволит снизить стоимость и металлоемкость реконструкции затворов действующих гидросооружений при повышении нормального подпорного уровн верхнего бьефа, что в целом снижает трудоемкость работ по реконструкции .The invention relates to hydraulic engineering and can be used to reconstruct existing hydraulic structures with an increase in the normal retaining level in the upstream. A known method for increasing the height of the gate span is to completely replace the existing gate with a new one. The disadvantages of this method are high cost, material intensity and labor intensity. There is also known a method of increasing the height of the gate span on existing hydraulic structures, including building up additional sections of span 2. The disadvantages of this method are the greater cost and intensity, due to the need to strengthen the structure of the entire existing span on the effect of additional hydrostatic load. The aim of the invention is to reduce the labor intensity of the work. The goal is achieved in that the extension of additional sections of the span is made from its lower edge. The drawing shows the shutter, a longitudinal section. The shutter consists of a span structure 1, main supporting joint 2, an additional section 3 of the span structure of joint 4 of an additional section located on the legs 5 of the superstructure 1. The method is carried out as follows. The superstructure 1 is raised, then the additional section 3 is expanded from the lower edge of the superstructure 1. After this, the additional section 3 is attached to the legs 5 of the superstructure with the help of hinges 4. Additional section 3 is calculated for the hydrostatic load in accordance with the new elevated level of the upper the pool The existing span remains unchanged, since the hydrostatic load on it remains the same. The use of the invention will make it possible to reduce the cost and metal consumption of the reconstruction of the gates of the existing hydraulic structures with an increase in the normal retaining level of the upstream, which generally reduces the complexity of the reconstruction works.
