ST 400 Borehole Drilling Machine Advantages

1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.

2. The drill rig has more positive speed stages and 14-500r / min speed range, and the output torque is 13428-250N.m.
3. The drilling rig has 2 reverse speeds, which is convenient for handling accidents.
4. The air compressor drilling rig adopts a long-stroke double-speed mechanism, a mechanical power head, and a power head stroke of 3400MM to improve drilling efficiency and reduce the occurrence of plugging and burning accidents.
5. The water well drilling rig rig uses dual oil pumps for oil supply. A single pump is used for drilling, and a double pump is used for confluence when lifting. The power loss is small and the auxiliary time is short.
6. The drilling rig machine has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.
7. The crawler water drilling rig machine chassis is adopted, and the trip of the outrigger
cylinder can be automatically loaded for 1.5m, which is convenient for relocation and transportation.
8. The drill rig reserves some functional interfaces in the hydraulic system, and can expand the functions according to the technological requirements of different users.

What is the construction technology of de watering well?

Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → de watering completion, pipe pulling → well sealing.

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%.
