ABSTRACT
In the article some problems that arise during the construction of spillway and backwater structures are considered. As an example we use the object near Novoselki village in Sergiev-Posad district of the Moscow Region. In the process of the hydraulic structures reconstruction the serious deviations from the project were made and the quality of construction works turned out to be very bad. These factors led to the accident on spillway structures. In order to avoid such situations it is necessary to design small hydrotechnical constructions with maximum simplified structures which could withstand overproject work conditions. The main conclusion is the following: the reliability of the designed structures depends mostly on contracting organizations qualification. The strictures were operating well on the objects where the contracting organization was high-skilled. The structures were built not according to the project and with poor quality on the objects built by unqualified contracting agencies. As a result they were damaged or even destructed. That’s why its necessary to choose the constructive decisions that are difficult to “spoil”: provide automatic water disposal through waste chute, don’t use slope protection made of precast concrete slabs.На примере объекта, расположенного у деревни Новосёлки Сергиево-Посадского района Подмосковья, рассмотрены проблемы, возникающие при строительстве малых гидротехнических водоподпорных и водосбросных сооружений. В ходе реконструкции гидротехнических сооружений пруда были допущены серьезные отклонения от проекта, а качество строительных работ оказалось очень низким. Это привело к аварии на водосбросных сооружениях. Во избежание подобных ситуаций необходимо проектировать малые гидротехнические сооружения таким образом, чтобы их конструкции были максимально упрощены и могли выдерживать сверхпроектные условия работы.
