Abstract
PURPOSE:To prevent the damage to a rubber and enable loading test under a high pressure by surrounding a rubber tube with a guidepost and a loading rigid plate in a rubber tube type sondo utilizing an excavated hole such as drilled hole. CONSTITUTION:A sonde comprises a steel cylindrical guide post 1, a rubber tube 2 inserted inside, a loading rigid plate fitted lengthwise into slender openings provided facing the circumference of the guid post 1 is such a manner as to move in and out. The loading rigid plate 3 is divided into three parts, upper, middle or lower, of which the upper and lower rigid plates 3a and 3c won't come off the post 1 while the central rigid plate 3b only is free to project. This sonde is inserted into a specified position in a drilled hole. At this position, when a high pressure fluid is forced into a rubber tube 2 through a tube 6, it expands to project the rigid plate 3 outward. At this point, the movement of the central rigid plate 3b is measured with a sensor 4 to determine the strength of the subsoil.
