Gk-200 type engineering drilling rig is a new generation of portable multi-purpose engineering survey and construction rig, which aims at optimizing the design of most of the same type drilling rigs in the domestic market. It is suitable for industrial and civil buildings, railways, bridges, etc. The engineering geological exploration of hydropower and other departments, as well as the construction of small diameter pile holes, have the following

Crawler Mounted Drill Rig Characteristics:
1, the speed range is wide, the gear is reasonable.
2, low speed, large torque, can be used for drilling machine sampling and pile hole construction.
3, equipped with front-and-back moving cylinder, so the whole rig can move freely 300 mm, which brings a lot of convenience to the drill.
4, hydraulic feeding, easy to operate, high drilling efficiency and low labor intensity.
5. The chuck of drilling machine adopts hydraulic roller type, easy operation, reliable clamping and no damage to active drill pipe.
6, compact structure, small size, light weight.
7. Adopt 9 spring reinforced large torque clutch, reliable clutch, larger torque transfer, strong impact resistance and long life.
8, increase input shaft spline specifications, torsion resistance significantly improved, longer life.
Why is the water well drilling rig not suitable for use in rainy days?
After the well is completed, it is necessary to pump water to check the results. Under normal circumstances, a large draw down pumping can be done. The stable duration of the water level shall not be less than eight hours, and the water flow of the dynamic water level of the well shall be measured at the same time. The well drilling project shall ensure the smooth drainage of the construction site, so the rainy season shall be avoided. When working while excavating, the excavation slope shall be determined according to the physical and mechanical properties of the soil layer, generally 1:1.5, and there shall be a certain distance from the toe of the spoil slope to the upper opening of the excavation. For large wells with water inflow from the shaft wall, the water inlet hole and inverted filter layer of the shaft wall must be arranged according to the design requirements, and the water inlet hole shall be prevented from being blocked during construction. The filter material enclosure at the aquifer shall meet the requirements, the backfill shall have a certain super elevation, and the frozen soil in the backfill in winter shall not exceed 15%.
