The purpose of drilling wells is mainly to develop groundwater resources, such as water resources for domestic use, agriculture, industry, etc. Well drilling is also suitable for hydrogeological exploration, construction projects, bridge foundation drilling and other projects.

Taking into account the factors of applying well drilling machine equipment work, well drilling work is best not to be carried out in the rainy season.
 
    1, well drilling work should be avoided in the rainy season, and the construction site should ensure smooth drainage.
 
    2、When working on the excavation side, the slope of the excavation side should be determined according to the physical and mechanical properties of the soil layer, generally 1:1.5, and there should be a certain distance from the foot of the abandoned slope to the top of the excavation.
 
    3, for the well wall into the water of the large mouth of the well, the well wall into the water hole and anti-filter layer, must be laid out according to the design requirements, construction to prevent the water hole into the blockage.
 
    4、The filter material surrounding the aquifer parts should meet the requirements, the backfill should have a certain ultra-high, and the frozen soil content in the backfill should not exceed 15% in winter.
 
    5, into the well should be pumping test, generally only a large drop in depth pumping, water level stability for a period of not less than 8 hours. Also determine the dynamic water level of the well and the flow of water out of the well.
 
    6, the bottom of the well into the large mouth of the well, the thickness of the counter-filter layer and filter media particle size, should be in accordance with the design requirements for construction, counter-filter layer before laying must be the bottom of the well mud and sediment removal. Filter material should be sieved to remove mud, the amount of square spare.

After years of research and production practice, according to the construction requirements, the enterprise has made many improvements to the drilling rig, so that the product is improved day by day. Our drilling rig has the characteristics of reasonable structure, economic and durable, simple operation, high mechanical efficiency, wide range of application, low maintenance rate, easy maintenance, etc., which is favored by the majority of users at home and abroad.
