Abstract: FIELD: civil engineering. SUBSTANCE: invention refers to design of bridge passages of various assignment built proceeding from pubic demand in close proximity to used, preferably reconstructed, motor-road and metro bridges and utilized upon their construction as sporting and recreation complexes, for instance ski complex. Sporting and recreation complex in the form of bridge passage over river near reconstructed two-level metro bridge includes superstructure linking upper and lower stations mounted on supports predominantly of broken section ( rod-type, lattice-type or X-shaped ). Longitudinal axis of section of bridge passage located above river is arranged in plan in parallel or at acute angle of 15 degrees with longitudinal axis of metro bridge. Axis of section positioned underneath is oriented in plan at acute angle with longitudinal axis of metro bridge and longitudinal axes of sections located above mentioned section form bend in plan, preferably U-shaped, with middle part oriented away from longitudinal axis of metro bridge. Uppermost section of superstructure has horizontal platform passing to section of superstructure positioned above river bank with maximal slope of sections following it amounting to 22-26%, section located next to it located above river bank and joined to it is shorter in length and has slope of 16-20%. Horizontal section located above support, passing over river and having longest length has slope from 14 to 16%. Section positioned after it has slope from 16 to 19% and goes into horizontal platform or platform with opposite direction of slope. Supports of section of superstructure of bridge passage are arranged uniaxially with line of arrangement of supports of river course superstructure of metro bridge or with displacement with reference to them towards sections of superstructure placed beneath. Ski path with inclinations corresponding to above-mentioned slopes of sections of bridge passage laid along sections of bridge passage. Line of suspended seat elevators and/or rope tows is laid at least on one side of ski path. EFFECT: construction of lightened bridge passage over river near used metro bridge with due account of dynamic loads created by it as well as complicated geological conditions of territory and its relief which secures maximal utilization of existing allotted land with considerable difference in heights. 7 cl, 3 dwg

Abstract: Изобретение относится к способу получения чистого диаммонийфосфата из очищенной экстракционной фосфорной кислоты (ЭФК), который может быть использован в пищевой, фармацевтической и химической отраслях промышленности. Способ заключается в том, что предварительно очищенную органическим экстрагентом - трибутилфосфатом - ЭФК на стадии концентрирования доочищают с помощью раствора, содержащего катионы NH 4   + , от остаточных сульфатов, а также соединений железа и алюминия, и ведется при соотношении NH 3  к сумме всех примесей в кислоте, равном 1,5 кг/кг. Очищенную таким образом ЭФК переводят на стадию получения ДАФ, где аммонизируют газообразным аммиаком до соотношения NH 3 :Н 3 PO 4  около 1,8. Полученную пульпу центрифугируют, а маточный раствор, имеющий слабощелочную реакцию и содержащий растворенные примеси, полностью выводят со стадии получения ДАФ на утилизацию. Кристаллический продукт - пищевой ДАФ - после отделения от маточного раствора без дополнительной сушки расфасовывают в тару и отправляют потребителю. Утилизацию маточного раствора осуществляют на стадии очистки ЭФК, используя в качестве источника катионов NH 4   +  при вышеописанной очистке, а также для получения удобрений. Одним из вариантов утилизации является использование маточника для промывки экстракта на стадии очистки ЭФК трибутилфосфатом. В результате этой операции раствор ДАФ попадает в рафинат, который представляет собой жидкое азотно-фосфорное удобрение (ЖКУ). Способ позволяет снизить концентрацию соединений фтора, железа, алюминия, свинца и мышьяка ниже норм, предусмотренных ГОСТом на пищевой ДАФ, упростить процесс за счет исключения операций дополнительного концентрирования и сушки, решить вопрос использования маточника после центрифугирования и получить дополнительный продукт - ЖКУ. 1 з.п. ф-лы, 1 табл.
