[0014] The utility model is described in detail below with reference to the accompanying drawings:

[0015] A soil sampling device for construction, comprising a conical support block 1, a cylindrical groove chamber 2 is arranged on the lower bottom surface of the conical support block 1, a central through hole 3 is arranged on the conical support block 1 at the top of the cylindrical groove chamber 2, a central nut 4 is fixedly connected in the central through hole 3, a hollow screw 5 is connected in the central nut 4, a cylindrical soil sampling barrel 9 is fixedly connected at the lower end of the hollow screw 5, the cylindrical soil sampling barrel 9 is arranged in the cylindrical groove chamber 2, and a hollow screw rotating handle 6 is fixedly connected to the upper end of the hollow screw 5; the bottom end surface area of ​​the conical support block 1 is large, which plays a role in stably supporting the soil sampling tool on the ground, and when the hollow screw 5 is rotated by the hollow screw rotating handle 6, the cylindrical soil sampling barrel 9 will rotate with the rotation of the hollow screw 5 The hollow screw 5 is provided with an internal thread, and the internal screw 7 is screwed in the inner cavity of the hollow screw 5. The lower end of the internal screw 7 passes through the lower port of the hollow screw 5 and is fixedly connected with a sampling soil block pressing plate 10. The sampling soil block pressing plate 10 is movably arranged at the upper end of the cylindrical soil sampling barrel 9. The upper end of the internal screw 7 passes through the upper port of the hollow screw 5 and is fixedly connected with the internal screw handle 8. If the internal screw handle 8 is not moved and only the hollow screw 5 is rotated, the internal screw 7 and the sampling soil block pressing plate 10 will rise and fall together with the hollow screw 5; if the hollow screw 5 remains stationary and only the internal screw 7 is rotated, the sampling soil block pressing plate 10 will rise or fall with the internal screw 7.

[0016] The conical support block 1 is set on the ground 11 of the sampled soil. The hollow screw rotating handle 6 is rotated clockwise, and the cylindrical soil barrel 9 rotates clockwise with the hollow screw 5 and rotates into the ground 11 of the sampled soil. With the continuous rotation of the cylindrical soil barrel 9, the soil entering the cylindrical soil barrel 9 is compacted.

[0017] When the cylindrical soil sampling barrel 9 enters the sampled soil surface 11 along with the rotating hollow screw 5, compacted sampled soil blocks 12 are obtained in the cylindrical soil sampling barrel 9. When the cylindrical soil sampling barrel 9 enters the soil to a certain depth, the rotation of the hollow screw rotating handle 6 is stopped, and then the hollow screw 5 is pulled vertically upward to move the entire tool away from the sampled soil surface 11. At this time, compacted sampled soil blocks 12 are set in the cylindrical soil sampling barrel 9.

[0018] After sampling is completed, the cylindrical soil sampling barrel 9 is taken out from the sampled soil ground 11 and transferred to the operating table 13 in the detection room; the inner screw handle 8 is pressed down vertically, and the downward pressure acts vertically on the operating table 13 through the inner screw 7, the sampling soil block pressure plate 10 and the compacted sampling soil block 12 in turn, and then, the hollow screw rotating handle 6 is rotated counterclockwise, and the hollow screw 5 rotates relative to the inner screw 7, so that the hollow screw 5 rises, and the hollow screw 5 drives the cylindrical soil sampling barrel 9 to rotate and rise together, so that the compacted sampling soil block 12 is removed from the cylindrical soil sampling barrel 9, and all sampling work is completed.
