There are many factors to consider when choosing the location of the well drilling machine. The followingDTH Drill PipeLet's talk about the influencing factors.

1.The foundation trench shall be excavated according to the stable side slope, and the stratum prone to collapse shall be excavated into a step shape. The bottom of the foundation trench shall be excavated to above the groundwater level.0.5-1m, the spacing between the tank wall and the outer wall of the shaft is generally 0.6-1m,Ensure the normal construction of the drilling rig.

2.The pouring blade foot should be selected in a solid soil layer, otherwise it should be tamped to prevent the well drilling machine from tilting during construction. The strength of the concrete blade foot should reach the design strength.At 70%, the shaft can be poured on the blade foot.

3.The drilling rig shall be fixed with steel drill to prevent the drilling rig from shifting at the wellhead during operation.

4.Turn the shaking wheel to wind the central wire rope of the drilling rig, and use the rope end hook to lift the middle sliding mark, so that the shaking wheel can rotate clockwise.DTH Drill Pipebring it up. When the sliding mark is one person high from the ground, hang the two wire ropes on both sides, and lift the faucet and the main drill pipe together. The lower ends of the two wire ropes are hung on the rocking wheel. Note that the winding direction is opposite to the main rope.One end of the 4-meter-long hose is fastened to the faucet, and the other end is connected to the water outlet of the water pump.

5.When installing drilling rig tower,Pay attention to the position of the main rope hook to the wellhead. The diesel engine is adjusted, a V-belt is connected to the outer groove on the three-groove pulley of the main engine, the inner groove is connected to the water pump, and the small throttle can be used for drilling after the water pump is supplied with water. The size of the working throttle is determined by the output of the water pump, so that the sediment can be washed up. It is appropriate to use one rod normally.1-10 minutes. The lower end of the pump is connected with the water inlet pipe, and the lower end of the water inlet pipe is placed in the circulating water pool. The water pool should be deep and there is room for sedimentation. The lower end of the suction pipe should be equipped with a filter.

6.DTH Drill PipeWhen drilling into large sand layer or deep sand layer, the feeding speed should be fast to avoid collapse caused by long-term stirring. If there is a collapse, please use slime to mix into thick mud and pump it in. If the collapse is too serious, you can fill the lumps of slime along the wellhead.,Heavy drilling after full,You can also put mud ball of mud column while drilling.
