Percussion Drill Impact drills is an important drilling machine pile foundation construction, it can adapt to different geological conditions, especially gravel layer drilling, hammer drill rigs adaptable than other types. At the same time, made with hammer drill holes into the hole after hole wall to form a layer around the dense soil, the stability of the cell walls and improve the pile bearing capacity, have a role. The most commonly used percussion drills have cz series, all of its components mounted on a trailer rig accessories, including motors, conveyors, winches and masts rig, overall traction. Punching machine drilling rig is the use of the toggle mechanism, the rotary motion into reciprocating motion dynamic changes, driven by the rope up and down movement of the ram. By hammer impact action of free fall, the pebble or rock crushing, drilling residue with mud (or dig tube with residue) discharged. The hammer has a variety of shapes, but they are mostly red cross-shaped blade. Due to the impact of the drilling rig is crushed into powder and granular rock drilling residue, the power consumption of a large, low drilling efficiency. So long auger, except when drilling using gravel layer, other formations have been replaced by other types of rigs. The importance of the drilling rig mud drilling fluid plays an important role in the drilling industry, it can be regarded as the drilling of blood. Common drilling fluid is generally divided into water, mud, clay-free fluid phase, emulsion, foam and compressed air, etc., through practice that the role of the drilling fluid following main points: 1, cleaning, lubrication, cooling drilling Machine bit; 2, clean bottom, carrying debris and assisted rock; 3, pressure balanced side wall rock drilling rig, closed and borehole stability; 4, can pass downhole drill bit required power and hydraulic power; 5, to reduce cuttings sedimentation rate, avoid heavy Shaka drill; 6, drilling of drill and casing buoyancy, can be reduced from tripping when load lift system. Drilling fluid displacement in general, the size of the pressure, and the choice of water, mud or emulsion and so have a huge impact on the cleanout effect. Capacity increases displacement, bottom cleaning drill cuttings and cooling increases, clean the bottom can not only improve the rate of penetration and bit of wear and tear can be reduced. But drilling fluids used in the process according to the provisions in certain operations, but also to understand some of the negative effects, or else would be counterproductive.
