Description
Technical Field

Background
In recent years, China builds more and more land on a fourth series soil layer, and a static sounding test is used as a continuity test for physical and mechanical parameters of the soil layer and is more and more widely applied to cohesive soil layers, silt soil layers, sandy soil layers and the like in the fourth series soil-soil layer.

The single-bridge static sounding probe with the sensor is pressed into the soil vertically at a constant speed through a hydraulic device, one data per 10cm of penetration resistance of the probe is recorded in a data acquisition instrument by utilizing a force sensor in the probe, soil layer classification is carried out through the acquired static sounding data, and the bearing capacity of foundation soil, the deformation index of the soil, the internal friction angle of the soil, the relative compactness of sandy soil and the like are determined.
The current single-bridge static sounding data acquisition adopts a manual point-pressing technology, namely, a technician performs point-pressing once every 10cm according to the depth of a static probe rod entering a soil layer by visual inspection or according to an identifier of the depth on the static probe rod, and the point-pressing enables a data recording function in a data recorder and penetration resistance data on a force sensor to be instantaneously connected, so that the penetration resistance data are recorded in the data acquisition instrument in real time. The data acquisition has the disadvantages that the penetration depth of the static probe rod is not guaranteed to be exactly 10cm when the static probe rod is pressed by a point at each time during visual inspection; for a static probe rod with marked lines, the accuracy of grasping the penetration depth can be influenced due to long-term abrasion. Therefore, the collected static exploration data has large errors to influence the engineering exploration quality. Therefore, the utility model is necessary to invent the single-bridge static penetrometer which can accurately grasp the penetration depth of the static probe.
