The dynamic cone detector is based on the "Highway Subgrade Design Specifications" (JTG D30-2004), "Highway Subgrade Construction Technical Specifications" (JTG F10-2006), "Highway Engineering Geological Survey Specifications" (JTJ 064- 98) and other regulations.
According to the bearing capacity of the foundation, it is divided into light power penetrometer and heavy power penetrometer.
1. Structural composition of light power penetrator:
It is mainly composed of three parts: a pointed cone head, a penetrating rod and a penetrating hammer. The weight of the hammer is 10 kg.
2. The structure of the heavy-duty power penetrating instrument:
It is mainly composed of three parts: the penetrating probe, the penetrating rod, and the penetrating hammer. The penetrating rod is generally 40 mm in diameter. Hebei Dahong Experimental Instrument Co., Ltd., a supplier of thickened drill pipe, has a piercing hammer weighing 63.5 kg.
