Description
Изобретение относитс к области исследований грунтов. Известны наконечники дл леиетрации грунтов, включающие конус и хвостовик дл креплени на.конеЧНнков к штанге пенетрометра . Недостатком известных наконечников вл етс то, что с их помощью невозможно зафйкси1ро.вать трение грунта по грунту в процессе иенетрационных испытаний. Цель изобретени - создание условий трени грунта по грунту. Указанна цель достигаетс тем, что конус выполнен с цилиндрическими ступен ми . На фиг. 1 изображен наконечник, вид сбоку , а на фиг. 2 - то же, вид сверху. Наконечник состоит из конуса 1 и хвостовика 2. Конус выполнен с цилиндрическими ступен ми, имеющими соотношени - 5 10 15 20 - tg-- , а отношение высоты ступени к высоте конуса принимаетс в пределах 0,05- 0,25. В процессе погружени наконечника в грунт под цилиндрическими ступен ми образуютс участки уплотненного грунта, которые передвигаютс вместе с наконечником и образуют «грунтовую рубашку в виде конуса с образующей под углом к вертикали . Предмет изобретени Наконечник дл пенетрации грунтов, В1ключающий конус и хвостовик, отличающийс тем, что, с целью соз дапи услови трени грунта по грунту, конус выполнен с цилиндрическими ступен ми.The invention relates to the field of soil research. Well-known tips for soil removal, including a cone and a shank for fastening the rim to the penetrometer rod. A disadvantage of the known tips is that with their help it is impossible to fix the friction of the soil on the ground during the ventilation test. The purpose of the invention is to create conditions for ground rubbing. This goal is achieved by the fact that the cone is made with cylindrical steps. FIG. 1 shows a tip, side view, and FIG. 2 - the same, top view. The tip consists of a cone 1 and a shank 2. The cone is made with cylindrical steps having ratios of 5 10 15 20 - tg--, and the ratio of the height of the stage to the height of the cone is between 0.05-0.25. In the process of immersing the tip into the ground, areas of compacted soil are formed under the cylindrical steps, which move together with the tip and form a "soil jacket in the form of a cone with a forming angle at an angle to the vertical. Subject of the invention. A tip for soil penetration, a B1 cone and a shank, characterized in that, in order to create a condition for rubbing the soil over the ground, the cone is made with cylindrical steps.
