Abstract
Description
Technical Field
[0001] This utility model relates to the field of static soil sampling test technology, and in particular to a static soil sampling test instrument. Background Technology
[0002] Traditional static cone penetration tests (PCTs) require in-situ testing, with the PCT providing the reaction force to uniformly press the static probe into the test soil. However, conducting PCTs at sea generally requires the construction of a fixed test platform or the use of an underwater PCT, which is costly. Furthermore, PCTs cannot provide a stable reaction force, and the static cone penetration data obtained from drilling floating platforms at sea are inaccurate due to the undulation of the waves. To address these issues, a PCT is proposed. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a static soil sampling test instrument, characterized in that it comprises a base, a soil sampler, a fixing hoop, a piston, a piston support, a force-applying disc, a static probe, a probe support, and a soil cutter. The fixing hoop is mounted on the base, the soil sampler is mounted on the fixing hoop, the piston is mounted on the soil sampler, the force-applying disc is mounted on the piston, the piston support is mounted on the base, the probe support is mounted on the base, the static probe is mounted on the probe support, and a soil cutter is mounted at the rear end of the static probe.
[0004] Furthermore, there are two fixing hoops, which are respectively fixed at the front and rear ends of the base. The soil sampler is set on the two fixing hoops. The front end of the soil sampler is provided with a piston. One end of the piston extends into the soil sampler, and the other end is connected to the force-applying disc through a gear. The force-applying disc is connected to the piston support through a bearing.
[0005] Furthermore, a probe support is provided at the rear end of the soil sampler, the static probe is fixedly mounted on the probe support, the head of the static probe extends into the soil sampler, the static probe is electrically connected to an external data receiver, and the cutting blade is mounted on the probe support.
[0006] The beneficial effects of this utility model are:
[0007] This invention utilizes a soil sampler to retrieve soil samples from the seabed. The soil sampler, filled with the sample, is fixed to two fixing hoops on a base and secured with bolts. A rotating force-applying disc on the piston support drives the piston, causing it to push the soil sample outward at a uniform speed, consistent with the static penetration speed specified in the standard. The soil sample and the static probe experience relative motion, and the static probe senses the force on the soil sample, transmitting the resulting data to an external data receiver to obtain the static penetration test data. After the soil sampler is completely pushed out, it is cut in two by a cutting blade to prevent soil accumulation at the probe support. By combining the piston, static probe, and other components, static penetration tests can be performed on the soil sample in the sampler. Since the soil sample is taken from the in-situ and tested immediately, the soil is subjected to minimal disturbance. Therefore, the test data obtained by this method is close to that of in-situ tests and can be used as a substitute for in-situ static penetration tests. Attached Figure Description
