Abstract

Изобретение относитс  к строительству, в частности к инженерно-геологическим изыскани м и исследовани м грунтов в основани х и сооружени х. Цель изобретени  - упрощение конструкции и повышение точности испытаний. Устройство состоит из камеры бокового давлени  1 с основанием 2, св занным стойками 3 с гидроцилиндром 4, крышкой 9 и крестовиной 13. В гидроцилиндре 4 установлен поршень 5, жестко св занный со штоком 19. В крышке 9 размещен плунжер 10, взаимодействующий через шарик 11 с винтовым прессом 12. Соотношение площадей поперечного сечени  штока 19 и поршн  5 до начала испытаний выбирают в соответствии с прин тым программой испытаний соотношением осевого и радиального напр жений. При испытани х образец 6 площадью поперечного сечени , равной площади штока 19, став т в резиновой оболочке между штоком 19 и основанием 2. Герметизируют зазор между крышкой 9 и корпусом 1. Крут т пресс 12, задавлива  плунжер 10 в камеру 1. Давление на верхний торец образца передаетс  при этом в пропорции, определ емой соотношением площадей поперечного сечени  поршн  и штока, и всегда пропорционально радиальному давлению в образце. 2 ил.The invention relates to the construction, in particular to engineering-geological surveys and research of soils in foundations and structures. The purpose of the invention is to simplify the design and increase the accuracy of testing. The device consists of a side pressure chamber 1 with a base 2 connected by pillars 3 with a hydraulic cylinder 4, a lid 9 and a crosspiece 13. A piston 5 is mounted in the hydraulic cylinder 4 rigidly connected to the rod 19. A plunger 10 is located in the lid 9 and interacts through the ball 11 with a screw press 12. The ratio of the cross-sectional areas of the rod 19 and the piston 5 before the start of the test is chosen in accordance with the accepted program of tests for the ratio of axial and radial stresses. During testing, sample 6 with a cross-sectional area equal to the area of the rod 19 is placed in a rubber casing between the rod 19 and the base 2. Seal the gap between the cover 9 and the body 1. Turn the press 12, pressing the plunger 10 into the chamber 1. The pressure on the upper the end of the sample is transmitted in proportion to the ratio of the cross-sectional areas of the piston and the rod, and is always proportional to the radial pressure in the sample. 2 Il.
