(54) СПОСОБ ПЕРЕКРЫТИЯ РУСЛА РЕК НАМЫВОМ(54) METHOD OF OVERLAPPING THE RIVER ROLE OF THE RIVER
1one
Изобретение относитс к способам neper крыти русла рек намывом, используемым при возведении различных гидротехнических .сооружений.The invention relates to neper river bedding methods by the alluvium used in the construction of various hydraulic structures.
Известен способ перекрыти русла рек, при котором перекрытие прорана производ т путем одновременного намыва и отсыпки песчано-гравелистого грунта с торцовым выпуском пульпы под воду против течени 1.There is a known method of blocking a river bed in which the overlap of a gash is made by simultaneous alluvium and dumping of sandy-gravelly soil with face pulp discharge into the water against current 1.
Недостатком этого способа вл етс использование при намыве и отсыпке гравелистого грунта, который не всегда имеетс в достаточном количестве в районе строительства , а также необходимость изготовлени дополнительного специального оборудовани дл выпуска пульпы под воду.The disadvantage of this method is the use of the gravel soil, which is not always available in sufficient quantities in the construction area, during the reclamation and dumping, as well as the need to manufacture additional special equipment for discharging pulp into the water.
Наиболее близким к предлагаемому по своей технической сущности вл етс способ , заключающийс в подаче грунта в поток сверх его транспортирующей способности и пр едующем перекрытии прорана при доп0лнительной подаче грунта. Согласно этому способу поток дополнительно насыщаетс грунтом за счет размыва им предварительно намытых резервов 2.The closest to that proposed by its technical essence is the method of supplying the soil to the flow in excess of its transporting capacity and stalling the overlapping of the passage with additional feeding of the soil. According to this method, the stream is additionally saturated with soil due to the washing out of previously accumulated reserves with it.
Однако известный способ примен етс преимущественно при перекрытии малых и средних рек. Применение его дл перекрыти крупных рек при значительных перепадах и расходах затруднено, так как в проране при больших скорост х не всегдаHowever, the known method is used mainly in blocking small and medium rivers. Its application for blocking large rivers with significant differences and expenditures is difficult, since it is not always
удаетс достигнуть перенасыщени потока и полного перекрыти русла рассредоточенным намывом, кроме того, за счет большого уноса грунта практически невозможно создание намывных резервов. Невозможность it is possible to achieve a supersaturated flow and complete overlapping of the channel with dispersed alluvium, moreover, due to the large soil abstraction it is almost impossible to create alluvial reserves. Impossibility
IQ достаточного насыщени потока грунтом снижает эффективность известного способа. Цель изобретени - повышение эффективности способа путем увеличени насыщени потока грунтом.IQ sufficient saturation of the flow of soil reduces the effectiveness of a known method. The purpose of the invention is to increase the efficiency of the process by increasing the saturation of the flow with the soil.
