Description
Определение размываемости грунтов в полевых услови х производитс устройством, которое выполнено в форме лотка.The determination of soil erosion in field conditions is made by a device that is made in the form of a tray.
Насто щее изобретение касаетс именно такого устройства, но лоток в нем выполнен бездонным с целью непосредственного воздействи воды на естественный грунт. Лоток снабжен острыми кра ми дл вдавливани последних в испытуемый грунт.The present invention relates to just such a device, but the tray therein is made bottomless for the purpose of directly affecting water on natural soil. The tray is equipped with sharp edges for pressing the latter into the test soil.
На чертеже фиг. 1 изображает вид сверху устройства, фиг. 2 продольный разрез и фиг. 3 - поперечный разрез по CD фиг. 1.In FIG. 1 is a top view of the device, FIG. 2 is a longitudinal section and FIG. 3 is a cross-section along the CD of FIG. one.
Предлагаемое устройство состоит из бездонного лотка /, снабженного наружным ограждением 2, с целью образовани замкнутого пространства «3 между наружной поверхностью лотка и внутренней поверхностью ограждени . Пространство это предназначено дл подачи в него воды, предохран ющей испытуемую на размывание поверхность от бокового впитывани жидкости.The proposed device consists of a bottomless tray / provided with an outer fence 2, in order to form a closed space 3 between the outer surface of the tray and the inner surface of the fence. This space is intended to supply water to it, which protects the surface to be tested from erosion by lateral absorption of liquid.
Ограждение 2 скрепл етс с лотком ) перегородками g. Лоток 1, кроме того, снабжен пробками Р дл помещени пьезометра и выпуска из лотка воздуха при наполнении его водой. Как указывалось выше, устройство имеет острые кра К-К, которые облегчают вбивание его в землю, трубку А дл выпуска из устройства прошедшей через него воды и трубку В дл подачи воды, проход щей через сетку-успокоитель S.The guard 2 is secured to the tray with partitions g. Tray 1 is also provided with stoppers P for placing the piezometer and releasing air from the tray when it is filled with water. As mentioned above, the device has sharp edges K-K, which facilitate driving it into the ground, tube A for discharging water passing through it, and tube B for feeding water passing through the damper net S.
Дл ограничени глубины вбивани устрюйства в землю оноСнабжено полками г. Около устройства расположен резервуар М, куда выпускаетс вода из трубки А. В замкнутое пространство 5 вода подводитс по трубке Е.To limit the depth of the drive-in of the device into the ground, it is equipped with shelves. Near the device is a reservoir M, where water is discharged from pipe A. In a closed space 5, water is supplied through pipe E.
Устройство устанавливаетс на земле на ровной поверхности; при желании определить скорость размывани грунта, лежащего ниже поверхности земли, верхний слой необходимо сн ть и устройство установить на требуемой глубине.The device is installed on the ground on a flat surface; If you wish to determine the rate of erosion of the soil lying below the surface of the earth, the upper layer must be removed and the device installed at the required depth.
Определение размываемости грунта производитс следующим образом. В наружное ограждение 2 по трубке Е подводитс вода и держитс под тем же давлением, под которым держитс вода во внутреннем ограждении лотка У; при этом нигде не должно быть проникновени воды из наружного ограждени во внутреннее.The determination of soil erosion is performed as follows. In the outer fence 2, water is supplied through the tube E and held under the same pressure under which the water is kept in the inner fence of the tray U; at the same time, water should not penetrate anywhere from the external enclosure into the internal enclosure.
