Water well drilling tools are often used in well drilling projects. In this project, the processing speed of water well drilling tools is also very important. It is not suitable to carry out in the rainy season. Factors, let’s analyze it for us now.

　　After making it, you need to pump water to check the effect. Under normal circumstances, you can do a large drawdown pumping. The water level is stable and continuous for no less than eight hours, and the water flow rate of the dynamic water level of the well is measured together. For large wells with water at the bottom of the well, the thickness of the filter layer and the particle size of the filter material should be constructed in accordance with the planning requirements, and the bottom mud and sediment must be removed before the filter layer is laid. The filter material should be sieved to remove sludge and measured for use.

　　The well-drilling project must ensure smooth drainage of the construction site, thus avoiding the rainy season. When digging while working, the excavation slope should be determined according to the physical and mechanical properties of the soil layer, usually 1:1.5, and there must be a certain interval between the spoil slope toe and the top of the excavation. Regarding the large well with water inflow from the shaft wall, the water inlet holes and filter layer of the shaft wall must be arranged in accordance with the planning requirements, and the water inlet hole should be prevented from being blocked during the construction process. The filter material enclosing fill of the aquifer position should meet the requirements, the backfill should have a certain height, and the frozen soil in the backfill should not exceed 15% in winter.
