Title: Cable Percussion Drilling Description: The learning objective is for students to understand the fundamentals and applicability of cable percussion drilling, to become familiar with the components and use of the different elements of the system, and to learn about its advantages and disadvantages. To this end, the content is structured in five sections: characteristics, drill bits, buckets, auxiliary elements, and advantages and disadvantages. Yepes Piqueras, V. (2014). Cable Percussion Drilling. https://riunet.upv.es/handle/10251/38656 Automatic description: In this video, a professor from the Department of Construction Engineering at the Polytechnic University presents the cable percussion drilling method. The objective is to understand its fundamentals, applicability, and components, as well as the advantages and disadvantages of the system. It is explained that this method is based on the percussion of a drill bit that strikes the bottom of the borehole, requiring the periodic removal of cuttings with scoops and the addition of water to facilitate collection. The system's characteristics are detailed, such as typical maximum depths of up to 150 meters, drilling diameters of 250 to 800 millimeters, and the mast height, as well as the frequency and height of the drill bit's drop depending on the ground hardness. It is also mentioned that it is powered by diesel or hydraulic motors and is mainly used in medium to low hardness ground. The drill bits, heavy steel elements, and the scoops used for cuttings removal are described. The auxiliary equipment necessary for the drilling operation is also addressed. The system's advantages include moderate cost and simple operation with large drilling diameters, while disadvantages include slow advance in hard rock and difficulties in unconsolidated materials. In conclusion, the simplicity and moderate cost of the method are highlighted, as well as its suitability for soft to medium soils and its limitation to an economical depth of up to 150 meters. Finally, the need for discontinuous operation for debris removal is emphasized.
