Description

Technical Field

[0002] Lightweight dynamic cone penetration testing (VCP) utilizes hammer energy to drive a cone probe of a specific size into the soil. The number of blows and the depth reached determine the soil layer type, engineering properties, and ultimately, a comprehensive evaluation of the foundation soil. In practical applications, soil sampling is sometimes necessary for further analysis. However, existing lightweight VCP devices lack soil sampling capabilities, requiring the use of an additional soil sampler. This not only increases operational steps but may also affect testing efficiency and accuracy. Therefore, a new lightweight VCP device capable of soil sampling is proposed. Utility Model Content

[0024] In this embodiment, as Figure 1-5As shown, the soil sampling module 2 includes an outer cylinder 21, an upper plate 22, a transmission sleeve 23, a lower plate 24, and six L-shaped soil sampling claws. The upper plate 22 and the lower plate 24 are circular steel plates, which are spaced apart at the lower end of the inner rod 3 by bearing sleeves. The lower plate 24 is welded and fixed to the upper end face of the conical head 1. The transmission sleeve 23 is a hollow cylindrical structure, which is sleeved on the inner rod 3 and located between the upper plate 22 and the lower plate 24, and is integrally formed with the outer cylinder 21. The turning point of the L-shaped soil sampling claw 25 is hinged to the edge through hole of the upper plate 22 and the lower plate 24 by a pin, and its inner end is hinged to the outer wall of the transmission sleeve 23. The outer cylinder 21 is made of seamless steel pipe, and its lower end passes through the upper plate 22. The outer cylinder 21 is welded to the transmission sleeve 23, and a long strip-shaped limiting groove 26 is opened on the upper outer wall. A cuboid limiting block 7 is welded to the corresponding position of the inner rod 3. The limiting block 7 is embedded in the limiting groove 26 to limit the relative axial displacement between the outer cylinder 21 and the inner rod 3.

When the soil sampling module 2 is switched to the extended state, the locking sleeve 42 is lifted upwards, keeping the inner rod 3 stationary, and the outer cylinder 21 is rotated clockwise. The soil sampling claw extends, and after rotating to the bottom, the locking foot 44 is locked on the left side of the limiting block 7 to complete the fixation, so as to carry out the soil sampling operation.
