The drilling rig is mainly used to develop groundwater resources, including domestic water, agricultural water and industrial water. It is also suitable for hydrogeological exploration, construction engineering, bridge foundation drilling, etc. Structure type of drilling rig: traction type, vehicle-mounted type and vehicle-mounted backup type. The general drilling rig is composed of diesel engine, friction clutch, gearbox, transfer case, transmission shaft, mud pump, fresh water pump, vacuum pump, rotary table, faucet, drawworks, hydraulic system, operating mechanism, mast, drilling tool, frame, etc.
After the well is completed, the dynamic and static water level of the well and the corresponding water output should be measured according to the construction drainage during the drilling process, and then the head of the master pump should be determined according to the height difference between the ground and the dynamic water level and the irrigation method you use. Pump flow should not exceed well water flow. According to the above two conditions, the corresponding pump should be purchased.
The location and layout of wells shall be reasonably arranged according to the actual local hydrogeological conditions. If there is no hydrogeological data, the existing water source wells nearby can be used as the basis for well layout. In areas where shallow groundwater is not abundant, do not blindly drill shallow wells; in areas where shallow groundwater is abundant, it is suitable for farmers to build shallow wells, but the layout of wells should not be too dense to avoid mutual influence between adjacent water source wells.
There are two construction methods for large wells: one is the large slotting method, manual excavation or blasting construction; the 2. is the open caisson method, drainage construction or undrained construction. Relative pumping construction generally uses mechanical hammer and manual hammer, using the gravity of the hammer to directly drive the straw into the ground.
