Product Overview
The OKB-087, also known as the Piling Penetration Tester in international standards and Series Mini Penetration Tester in China, is a specialized instrument designed for the detection of the compactness and uniformity of large-scale fill projects after rolling. It is widely used in civil construction, highways, bridges, municipal drainage, oil pipeline, and hydraulic embankments.
Key Features
The OKB-087 is characterized by its portability, flexibility, and rapidity, allowing for real-time monitoring of the rolling site. The technical parameters of this device are derived from conventional ring knife tests, ensuring that the results are closely related to soil engineering tests.
Traditional ring knife tests require approximately 8 hours to obtain results, which is often too time-consuming to be of practical use during the construction process. This has been a common concern among engineers and construction supervisors. However, the OKB-087 addresses this issue by providing a quick and efficient on-site testing solution.
Applications
The OKB-087 is particularly useful in detecting weak points and potential problems at the bottom of the fill, which can guide the acceleration of construction progress and ensure quality. It has been widely used in projects such as the Beijing-Haikou Expressway in Hubei and Hunan provinces, as well as the Yangtze River and Songhua River embankments.

Operation
The operation of the OKB-087 is straightforward. Simply drill a hole or remove 1/4 of the surface soil layer, insert the instrument vertically, and the test can begin. The device is easy to use, and technicians can quickly master its operation by referring to the manual.
The OKB-087 is suitable for the layered rolling and inspection of fills, as well as for random layer inspections by quality supervision stations and supervision companies. It can also be customized with longer probe rods upon special request.
Conclusion
The OKB-087 is a valuable tool for ensuring the quality and efficiency of fill projects. Its ability to provide quick and accurate results on-site makes it an essential instrument for engineers and construction supervisors. With its user-friendly design and versatile applications, the OKB-087 is poised to become a standard in the field of soil engineering.
