Vertikal drenaj tizimlari nasosli va quvurli quduqlardan foydalanadigan drenaj tizimlardir. Maqolada vertikal drenaj samaradorligini oshirish uchun oqimchali nasosdan foydalanish taklif etilgan. Oqimchali nasosdagi gi dravlik jarayonlarni o‘rganish uchun laboratoriya qurilmasi tayyorlandi va tadqiqotlar olib borildi. O‘tkazilgan tadqiqotlarda oqimchali nasosdagi so‘rish jarayoniga haydash quvuri diametrining ta’siri o‘rganildi. Haydash quvuri d = 40 mm bo‘lganda, injeksiya koeffitsiyentining maksimal qiymati 50 %ga yetdi. Laboratoriya tadqiqotlari natijalari tahlili asosida taklif etilgan vertikal drenaj tizimida qo‘llaniladigan oqimchali nasosning so‘rish qobiliyati va so‘rish balandligini aniqlash bo‘yicha bog‘lanish olindi.

Вертикальные дренажные системы – это такие системы, в которых используются насосы и буровые скважины. В статье предлагается использовать струйный насос для повышения эффективности вертикального дренажа. Была изготовлена лабораторная установка и проведено исследование по изучению гидравлических процессов в струйном насосе. В проведённом исследовании изучена зависимость процесса всасывания в струйном насосе от диаметра напорной трубы. Коэффициент инжекции достиг максимального значения 50 % при диаметре напорного трубопровода d = 40 мм. На основе анализа результатов проведённых лабораторных исследований доказана связь показателей всасывающей способности и высоты всасывания струйного насоса, используемого в предлагаемой системе вертикального дренажа.

Vertical drainage systems are systems that use pumps and tube wells. The article proposes the use of a jet pump to boost the efficiency of vertical drainage. A laboratory equipment was used study the process of using a jet pump. The research examined the impact of the pressure pipe’ diameter on the suction process in a jet pump. The injection coefficient reached a maximum value of 50% at the efficiency of the flow meter d = 40 mm in pressure pipe. Based on statistical analysis of laboratory research findings, a relationship was retrieved to determine the suction capacity and suction height of the jet pump used in the proposed vertical drainage system.
