Description

Technical Field

[0001] The utility model relates to the field of engineering detection technology and equipment, and in particular to automatic light cone dynamic penetration test equipment. Background Art

[0002] The dynamic penetration test is a common in-situ test method for investigating the geological conditions of soil layers before the construction of various civil engineering and exploration projects. The traditional test method is to use a penetrating hammer with a certain mass to hit the probe rod, drive the cone probe at the lower end of the probe rod into the soil to a certain depth, and determine the properties of the geological soil layer through the relationship between the number of hammer blows, penetration resistance and knockdown depth. Existing cone dynamic penetration test equipment requires manual and accurate recording of the number of hammer blows and a large number of knockdown depth changes. At the same time, the hammer energy is calculated and recorded by multiplying the weight of the heavy hammer in the number of hammer blows by the drop distance, which leads to large human errors in the test data and poor accuracy of the test results.
