ST 200 Pneumatic Drilling Rig Drilling Attentions

1. The drilling unit must first drill holes, take samples and draw the drilling profile structure diagram (histogram).

2. According to the histogram: geological structure, the upper pipe and filter pipe of the well shall be made, and the drilling diameter shall not be less than 300mm.

3. After the well is drilled and the pipe is laid, the backfilling amount of filler shall be 1.8-2.0 m3, and it must be ensured that the outside of the well pipe wall is more than 70 mm. The filter material is siliceous sandy pebble without impurities. It is better to mix according to the pebble particle size (20-40mm). During filling, materials shall be fed layer by layer manually. It is strictly prohibited to backfill filter materials mechanically and soil into the well. Gravel filling method: generally, circulating water or still water is used for gravel filling. If the filling quantity and height of filter material are greatly different from the plan, find out the reasons, deal with them properly, and record the filling results.

4. After well completion, the well pipe shall be vertical and not inclined.

5. The polyethylene plastic pipe wall of the well pipe is 8mm thick. The well pipe adopts a drilling filter. The drilling hole is 18-20mm, and the drilling rate is not less than 25%. The well pipe shall be overlapped and the filter screen shall be fixed. Screw joint is adopted for well pipe lapping and drilling φ 8mm hole, mounting φ 10mm screw. The mesh of the filter screen is about 25 mesh, and the filter screen is wrapped in 2 layers.
