Rig installation and removal: 1. Drill installation, before the demolition, mechanical technician must be installed in accordance with the development of specific manufacturer's instructions for use, disassembly processes, programs and technical security measures, and strictly enforced. 2, the structure lifting by professional hoisting personnel command, and select the appropriate depending on the specific weight of the rope. In high winds, heavy rain or hoisting sight unknown circumstances, prohibited rig installation and removal operations. 3, when the rig drilling rig installed to ensure a base level and secure. 4, re-testing and adjustment of verticality After installation of the drilling rig, drill center deviation shall meet the requirements of the construction process. Percussion Drill Impact drills is an important drilling rig pile foundation construction machinery, 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 impact cz series percussive drill rigs have all of its components mounted on a trailer, including motors, conveyors, winches and masts, the 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 freefall impact action long auger, the pebble or rock crushing, drilling residue with mud (or dig slag tube) is 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 drilling rig, drilling efficiency is very low. Thus, except in the drilling using gravel layer, other formations have been replaced by other types of rigs. Impact drill, drill, Long industry machinery supplied by Shandong Machinery Co., Ltd.
