In situ testing devices such as the dilatometer, the piezocone, the pressuremeter, and the field vane generally require the use of a drill rig for penetration through soils. This paper describes a multipurpose portable pushing frame built at the University of New Hampshire and designed to be used with most in situ testing probes. This rig is compact, inexpensive, easy to use, and can operate on sites usually not accessible to conventional drilling rigs.
