Description
Изобретенный прибор предназначен дл определени напора, соответствующего напору фильтрационных вод под гидротехническими , сооружени ми, выпираю1щему слой грунта определенной глубины. Дл «той цели применен стержень с тупым концом, устанавливаемый на заключеннь|й в сосуде грунт, через который снизу подаетс вода под определенными напорами , и по скорости погружени стержн в грунт суд т о моменте выпора грунта (критический напор).The invented device is designed to determine the pressure corresponding to the pressure of the seepage water under hydraulic engineering structures, protruding a layer of soil of a certain depth. For this purpose, a blunt rod was installed, installed on the soil enclosed in the vessel, through which water is supplied from below under certain pressures, and judging by the speed of the rod in the soil, the moment of soil removal (critical pressure) is applied.
На фиг. 1 схематического чертежа показан вертикальный разрез прибора, на фиг. 2-график, составленный по полученным посредством прибора данным.FIG. 1 shows a schematic vertical section of the device; FIG. 2-graph drawn from the data obtained by the device.
Предлагаемый прибор состоит из щика 3, в который насыпан слой, испытуемого грунта 4 и в который снизу, по трубке 2, поступает вода из напорного бака /. На грунт 4 вертикально устанавливаетс стержень 5 с тупым концом (лучше с площадью поперечного сечени в 1 см и весом 1 кг, тогда давление на грунт будет равно 1 кг/сл 2).The proposed device consists of a box 3, in which a layer is poured, of the test soil 4 and into which water from the pressure tank comes from pipe bottom 2. Rod 5 is vertically mounted to the rod 5 with a blunt end (preferably with a cross-sectional area of 1 cm and a weight of 1 kg, then the pressure on the soil will be 1 kg / cl 2).
При помощи прибора 6, 7, 8 замечаетс сначала осадка стержн 5 в сухом грунте, затем при разных напорах поступающей снизу воды. В соответствии с увеличением напора стержень 5 будет погружатьс в грунт 4 вначале, постепенно, а затем резко. Резкое погружение стержн будет соответствовать критическому напору.With the help of the device 6, 7, 8, the sediment of the rod 5 is first noticed in dry soil, then at different pressures of the water coming from below. In accordance with the increase in head pressure, the rod 5 will be immersed in the soil 4 at first, gradually, and then abruptly. A sharp immersion of the rod will correspond to a critical head.
Значени величин Н, I и hoc и др. занос тс в таблицу, на основании которой строитс график, изображенный на фиг. 2.The values of H, I, and hoc, etc. are tabulated on the basis of which the graph shown in FIG. 2
Предмет изобретени .The subject matter of the invention.
Прибор дл определени напора, соответствующего напору фильтрационных вод под идротехническими сооружени ми, выпирающему слой грунта определенной глубины, отличающийс применением стержн 5, вертикально поставленного на поверхность заключенного в сосуде грунта, через который подаетс вода под определе,нным переменным напором, дл того, чтобы наблюдать момент выпора грунта по интенсивности погружени этого стержн в грунт.A device for determining the pressure corresponding to the pressure of filtration water under technical structures, protruding a layer of soil of a certain depth, characterized by the use of a rod 5, vertically placed on the surface of the soil enclosed in a vessel, through which water is supplied under a certain variable pressure, in order to observe the moment of removal of the soil according to the intensity of immersion of the rod into the soil.
