Pressuremeter has working tail as wedge with sharpening at beneath and pressure gauges placed at one of sides of wedge in level with its working surface and with constant pitch at geometric dimensions of the wedge determined from relations α≤ 6°, b ≥ 2,5·t, where α - angle between working edges of the wedge; b – width of face of wedge; t – maximal thickness of the wedge. Pressuremeter has measuring device for vertical resistance to wedge immersion to soil, end surfaces of the wedge have slots – micro-depressions with respect to edges of wedge-forming facets. The lower end of the wedge is made from two separate parts each of which is placed with its tail element in the placed higher part and is made with support at tension-indicators. |
