Dynamic Cone Penetrometer, Pneumatic Driven

Dynamic Cone Penetrometer, Pneumatic Driven

Dynamic Cone Penetrometer, Pneumatic Driven is used to measure the strength and deformation properties of the soils according to ISO 22476-2. It consists of a steel rod with a cone-shaped tip that is driven into the ground by a pneumatic hammer. The penetration resistance of the soil is measured as the depth at which the cone penetrates the ground with each blow from the hammer. This data can then be used to assess the soil's bearing capacity, compaction, and other engineering properties. The pneumatic hammer allows for rapid testing, making the Pneumatic Driven Dynamic Cone Penetrometer a popular choice for field investigations and construction quality control.

Pneumatic Dynamic Probing Light testing and Dynamic Probing Medium (DPM) testing set is suitable for doing lightweight, 10 kg, and medium heavyweight 30kg dynamic. The apparatus comprises a pneumatic power pack with a four-stroke gasoline engine that drives through a flexible shaft with a lifting mechanism. It is a fully automated pressure-release valve. Supply with a 10 kg weight and 20kg optional weight. This apparatus is comply ISO standards for medium-weight test apparatus with 30kg mass and 20 cm drop height. It is a cost-effective, simple, and reliable tool suitable for light dynamic penetration testing up to approx. 10 - 12 m depth.

Features of Dynamic Cone Penetrometer, Pneumatic Driven

Measurement of Strength and Deformation Properties: Both the DCP and the DPM testing set are designed to measure the strength and deformation properties of soils according to ISO 22476-2 standards.
Steel Rod with Cone-Shaped Tip: Both devices feature a steel rod with a cone-shaped tip that penetrates the ground under the force of a pneumatic hammer.
Pneumatic Hammer: The pneumatic hammer drives the cone into the ground, and the resistance encountered is measured to determine soil properties.
Rapid Testing: The pneumatic hammer allows for rapid testing, making it suitable for field investigations and construction quality control where quick results are necessary.
Suitable for Various Weight Ranges: The DPM testing set is suitable for lightweight (10 kg) and medium heavyweight (up to 30 kg) dynamic probing. This versatility allows for testing in different soil conditions.
Fully Automated Pressure-Release Valve: The apparatus is equipped with a fully automated pressure-release valve, enhancing safety and ease of use during testing.
Depth Capacity: The DPM testing set is suitable for depths of approximately 10 - 12 meters, making it suitable for a range of soil investigations.

Standards

TRL (Transport Research Laboratory): TRL is an abbreviation for Transport Research Laboratory. It's an organization in the UK that conducts research, consultancy, and testing related to transportation and infrastructure. In the context of soil testing, TRL refers to standards or guidelines developed by this organization for conducting tests and assessments related to transportation infrastructure, such as roads, railways, and airports. These standards typically cover various aspects of soil testing, including compaction, strength, and deformation properties, to ensure the safety and reliability of transportation infrastructure.

ISO 22476-2: "Geotechnical investigation and testing - Field testing - Part 2: Dynamic probing". ISO 22476-2 provides guidelines for conducting dynamic probing tests in the field to assess soil properties. It covers procedures, equipment specifications, and data interpretation methods for dynamic probing tests, including those using pneumatic-driven dynamic cone penetrometers. Compliance with ISO 22476-2 ensures that dynamic probing tests are conducted consistently and accurately, allowing for reliable assessment of soil conditions for engineering purposes.

Test Procedures of Dynamic Cone Penetrometer, Pneumatic Driven

Preparation:

Ensure that the DCP equipment is in good working condition, including the pneumatic hammer, steel rod, cone tip, and measurement devices.
Calibrate the equipment if necessary according to manufacturer specifications.
Select the appropriate weight for the dynamic cone and attach it securely to the rod.

Site Preparation:

Select test locations representative of the soil conditions under investigation.
Clear the test area of any debris or obstructions that may interfere with the penetration of the cone.

Driving the Cone:

Position the DCP over the test location.
Insert the cone tip into the ground vertically.
Apply blows from the pneumatic hammer to drive the cone into the soil.
Record the number of blows required to achieve specified depths or resistance levels.
Continue driving the cone until reaching the desired depth or refusal, typically indicated by a significant increase in resistance.

Measurement and Recording:

Measure and record the depth of penetration after each blow or at specified intervals.
Record the blow count for each specified depth interval.
Optionally, measure and record additional parameters such as pore pressure, pore water pressure, or soil moisture content if relevant instrumentation is available.

Data Interpretation:

Analyze the recorded data to assess soil properties such as bearing capacity, compaction, and layer thickness.
Compare the test results with relevant standards or guidelines to evaluate soil suitability for engineering purposes.
Consider additional factors such as soil type, moisture content, and environmental conditions in the interpretation of test results.

Reporting:

Prepare a comprehensive report documenting the test procedures, equipment used, test results, and interpretations.
Include relevant details such as test location, depth profiles, blow counts, and any observations or notes regarding soil conditions.
Provide recommendations or conclusions based on the test results, including any implications for construction or design.
