The invention relates to an automatic portable soil penetration test device. The device comprises a base, a stand column, a compaction rod, a connecting rod, an annular belt, a heavy hammer, a locking frame, a heavy hammer lifting table, a motor, a noose wheel, a lifting steel cable, a depth detection ruler, a top beam, a heavy hammer impact table, a controller and a transmission device. A stand column is fixed between the base and the top beam. The heavy hammer lifting table is fixed above the heavy hammer impact table through a connecting rod; the connecting rod slides on the stand column. One end of the compaction rod is fixed at the lower end of the heavy hammer impact table; a plurality of locking frames are arranged at the upper end of the heavy hammer, and a plurality of corresponding noose wheels are arranged on the heavy hammer lifting platform; and the lifting steel rope is arranged between the corresponding locking frame and the noose wheel. The noose wheels are driven by a motor and a transmission device to rotate synchronously; the counter weight is provided with an annular belt, and the depth detection ruler is arranged on the counter weight through the annular belt; the bottom end of the depth detection ruler leans against the bottom end of the heavy hammer; and the controller is respectively connected with the motor and the depth detection ruler.The test device can automatically record the hammering times and the soil injection amount.
Description
technical field [0001] The invention belongs to the technical field of engineering quality inspection, and in particular relates to an automatic portable soil penetrating test device. Background technique [0002] The portable penetrating test is to use a certain hammering energy (hammer weight 10kg) to drive a conical probe of a certain specification into the soil, and judge the type of soil layer according to the depth reached by the number of hammering penetrations, and determine the engineering properties of the soil. Make a comprehensive evaluation of the foundation soil. Because the portable penetrating equipment is simple and easy to use, it can be used to provide the bearing capacity and deformation modulus of the shallow foundation foundation; check the degree of compaction of the foundation soil; check whether there is an underlying soft layer in the base and other detection work. Usually, in the backfill soil penetrating test, the penetrating test is often used, ...
