Rotary drilling rig is very important in engineering construction, master some efficient construction tips, can greatly improve the efficiency and quality of work. These practical tips are detailed below.1. Accurate planning before construction: comprehensively survey the geology, select suitable dr Read More

The construction of bored pile is mostly carried out in quaternary loose strata, so collapse is the most common accident in the construction of bored pile1. Signs before an accidentSlump hole and shrinkage hole occur in drilling construction, generally speaking, it does not happen suddenly. There we Read More

1. High drilling efficiency: the rotary drilling rig has sufficient power and large torque, and the single drilling depth is far more than that of the screw drilling machine, which can quickly complete a large number of drilling and greatly shorten the construction period.2. Strong geological adapta Read More

1. Check the appearance of wear: If the drill shell, drill pipe and other parts have a large number of scratches and deformation, it indicates that it is used frequently, which may affect the subsequent life.2. Check working hours: the number of working hours is large, the components run for a long Read More
