Description

Изобретение относитс  к области строительст ва и может быть. использовано дл  определени  динамических характеристик грунтовых оснований фундаментов при различных видах их деформации . Известен виброштамп дл  определени  динамических характеристик, включающий вибратор , штампы, различные по высоте, и балласт 1J. Недостатком устройства  вл етс  низка  точ ность измерений. Наиболее близким к изобретению техническим решением  вл етс  штамп дл  определени  динамических характеристик грунта, включаюший вибратор, опорную плиту, измерительные приспособлени  и балласт 2. Недостатком устройства  вл етс  недостаточна  точность измерений, обусловленна  тем, что устройство не обеспечивает создание  вно выраженной силы горизонтального направлени . Целью изобретени   вл етс  повьпиение точности определени  коэффициента упругости и модул  затухани  при упругом равномерном опвиге. Достигаетс  это тем, что в виброштампе дл  определени  динамических характеристик грунтов, включающем вибратор, опорную плиту , измерительные приспособлени  и балласт,. опорна  плита снабжена кронштейнами с винтами и п тами с шаровыми шарнирами, причём винты пропущены через концы кронштейнов и оперты на шарниры п т, которые размешены по углам треугольника. Изобретение по сн етс  чертежом, где на фиг. 1 изображен общий вид виброцпампа; на фиг. 2 - разрез А-А на фиг. 1. Виброштамп состоит из двухзальноговибратора 1 с двум  парами дебалансов, балласта 2, измерительных приспособлений (на чертеже не показано), и опорной плиты 3 с трем  кронштейнами4, снабженными винтами 5, опирающимис  на п ты 6 посредством шаровых шарниров. Лапы дл  удобства обслуживани  вьшолнены съемными, а п ты 6 размещены по углам треугольника. Дл  получени  деформаций сдвига грунта под винты 5 укладываютс  п ты 6, после чеThe invention relates to the field of construction and may be. used to determine the dynamic characteristics of soil foundations of foundations for various types of deformation. A vibrostamp for determining dynamic characteristics is known, including a vibrator, punches of various heights, and a ballast of 1J. The disadvantage of the device is low measurement accuracy. The closest technical solution to the invention is a stamp for determining the dynamic characteristics of the soil, which includes a vibrator, a base plate, measuring devices and ballast 2. The drawback of the device is the insufficient accuracy of measurements, due to the fact that the device does not provide a clearly pronounced strength of the horizontal direction. The aim of the invention is to improve the accuracy of determining the coefficient of elasticity and attenuation modulus for elastic uniform insertion. This is achieved by the fact that in a vibrostamp to determine the dynamic characteristics of soils, including a vibrator, a base plate, measuring devices and ballast ,. The base plate is provided with brackets with screws and points with ball joints, the screws being passed through the ends of the brackets and supported on hinges n t that are placed at the corners of the triangle. The invention is illustrated in the drawing, where in FIG. 1 shows a general view of vibrocamp; in fig. 2 shows section A-A in FIG. 1. The vibrostamp consists of a two-arm vibrator 1 with two pairs of unbalances, a ballast 2, measuring devices (not shown in the drawing), and a base plate 3 with three brackets 4 fitted with screws 5 supported on pts 6 by means of ball joints. Paws for ease of maintenance are made removable, and marks 6 are placed at the corners of the triangle. To obtain the shear deformations of the soil, screws 5 are stacked in heel 6, after
