Mobile unit for static testing of soils with piles and stamps

Abstract

Small-sized mobile unit for static testing of soils with piles and stamps belongs to the field of engineering surveys and is designed for static testing of soils with piles and stamps for indentation in the design and construction of buildings and structures. The installation consists of a jack, a thrust structure, anchors, a control system and displacement measurement sensors. The thrust structure is a dismountable, bolted, spatial structure in the form of a geodesic dome with a plate located in the upper tier and anchors located around the perimeter at the base of the installation; the thrust force from the jack is evenly distributed by the plate through the nodes of the geodesic dome over all its elements and is perceived by the anchors. The main advantage of using the new installation is to increase its mobility during transportation, installation and dismantling of all the main elements by reducing their length and weight. As a result, it becomes possible to conduct static tests of soils with piles and stamps in hard-to-reach and remote areas, without the use of large-sized construction equipment.
