Nanning leiwo rotary drill in the subway "tough guy"
Recently, leiwo power construction of subway construction site in Guangxi, Nanning metro line five, to create a perfect image of "unyielding men".
It is reported that this is to participate in the construction of Revo FR630D rotary drill, after 3 hours after the operation, the rotary drill 20-26 meters underground continuous rock drilled 0.8 meters in diameter, accumulated up to 6 meters of granite gneiss, the presence of personnel are all really impressive, glorious become iron road "tough guy".
Nanning leiwo rotary drill in the subway "tough guy"
Revo FR630D nicknamed the "tough guy" of the rotary drill adopts three motor reducer, according to different working conditions design combination of power system, large output torque, strong adaptability, high matching degree, embedding ability strong, can achieve a variety of complex formation geological construction for 24 hours.
Said leiwo rotary drilling service personnel, leiwo rotary drill has been "economic, efficient, reliable and intelligent" characteristics in the industry wide acclaim. Revo FR630D won the title of the ten rotating pile machinery China engineering machinery industry annual drilling, it is one of the outstanding representatives of.
On the hard rock field condition judgment, Revo FR630D rotary drill than other machines with tons of on-site construction efficiency about 30% meters high, and the hole quality and core integrity also has certain advantages, worthy of the title of "tough guy".
It is known that the rock compressive strength in the field is generally above 80MPa, up to 140MPa. According to the construction standard, the pile diameter is 0.8-1.2 meters, and the pile depth should reach 25 to 40 meters, which means that the drilling tool must be embedded in the hard granite 20 to 26 meters. This difficulty is to make the scene of many rotary drill boss straight hair, but has a Revo FR630D rotary drill Zhou Chengliang still Mianbugaise calm command machine trip, upgrade.
Especially with innovative applications in a working device, walking chassis, hydraulic system, control system and other key parts, Revo FR630D rotary drill compared with the same level of tons of rice products have a wide scope of operation, high construction efficiency, strong power, stable performance, high reliability, convenient installation and other characteristics, can be regarded as a national leader products of the same level.
This brilliant "tough guy" for the benefit of the railway construction, but also for the benefit of mankind, good "firm and unyielding character".
