Rotary drilling is an advanced construction method widely applied in fields such as bridges, building foundations, and ground improvement. It relies on rotary drilling rigs, which use drill bits to cut through soil or rock and discharge it out of the borehole to create pile holes. The quality and ef Read More

During the operation of rotary drilling rigs, vibration is unavoidable, especially in hard rock layers or complex geological conditions. Excessive vibration can not only damage key components of the equipment but also lead to safety accidents, affecting construction progress and costs. Therefore, mi Read More

Rotary drilling rigs are widely used in foundation construction due to their efficiency and flexibility. In rock drilling operations, their performance directly affects construction efficiency and project quality. The rock drilling capability of rotary drilling rigs mainly depends on the pressure mo Read More

(1) Keep the air filter clean If the air filter is too dirty, it will cause air flow resistance, incomplete combustion of the mixture, the engine power drop. Tests show that: when the air filter partially blocked, fuel consumption will increase by 5%. Driver maintenance air filter should do Read More

Problems and countermeasures of deep pile construction 1, construction efficiency is low, the main reason is to lift down the drilling tool takes up too much time, the efficiency of the drill pipe to transfer the drilling pressure is low.Countermeasures: (1) raise the length of the drill bit, so tha Read More
