Drilling operation
- familiar with operation essentials before entering the actual operation.
1, site selection
Select the drilling position, selecting wellhead position, with a shovel dug deep 30-50cm, wellhead diameter 30cm. Will be installed to stand above the wellhead on it. General drilling wellhead of the position of the soil surface for the real secret to good, below could not have bricks, gravel, firewood overhead phenomenon, in order to avoid drilling operations appear seepage, landslides, subsidence and other phenomena, resulting in potential safety problems.
2, dig reservoir
I Guchi position about four metres (can also according to the actual terrain, length of pipe spacing) dig a diameter greater than 1.5 square meters, one meter deep reservoir, pump pressure cross hanging in the pool (in a horizontal plane cover pump is appropriate) will pump pipe on the other end of the drilling machine with the top of the tap is connected with wood.
3 boot
Drills with the link rod fastening, the main control machine hand hand hoist lift your nose, another person with the connected to the first section with the drill pipe, main control machine hand hand hoist slowly falling head machine and other people with walking drill pipe slowly will drill through the hole of the base on the drilling hole and vertical stabilizer, start drilling rig and pump, the rotation of the drill rods is driven into the ground.
Remember: when the drill bit rotates clockwise, can not be reversed, so as to avoid falling out of drill pipe.
4, on the change of drill pipe,
After entry into the first section of the drill pipe, with the close the insurance deduction, in unloading rod card, main control machine hand reverse inverse clockwise rotating drill pipe, head movements with the drill pipe are separated, the elevator head, with another person take a drill pipe, manual rotation of the top wire is connected with the head, at the lower end of the butt joint, master hand machine boot clockwise rotation of the drill pipe is screwed, open insurance card, remove the unloading rod card, boot along clockwise rotation, continue to drill down. So repeat the above action can be repeated. According to what you want to find the ideal water depth of geological sand can be.
5, unloading drill pipe:
Drill down to the desired depth of aquifers, water sand depth, stop drilling rig, only the opening of the water pump pressurized water flushing wash wells, when underground no sediment pan can begin unloading the drill rod of the. First, close the insurance button, insert the rod card, the transfer of the nose with the drill pipe separation. Secondly, the discharge rod device is arranged on the machine head, fastening, nose landing will be discharged rod on the same base drill pipe on it into the slot, turn buckle hanging lifting, when the lower end of the drill rod joint at the rose to base insurance card above stop, tighten the insurance are fastened, in unloading rod card, overturned, and the drill pipe is automatically unloaded, with people can be removed, so repeated operation.
Note: when the drill pipe is discharged to the drill bit, turn off the electric power to hand, and slowly put forward the base to avoid the collision.
Three, the exchange of experience
The drilling machine for the general civil small fully automatic drilling machine, drilling diameter 20cm, 6 inches or less, the experimental depth of 160 meters (Xingtai Hebei production area - plain area) economic depth of 120 - 80 meters. Supporting well pipe diameter less than 16cm (6 - 1 inch home wells), according to the local geological structure, and customer economic capacity to bear. Don't blindly seeking deep. In general, a single day workload is appropriate.
Diameter drill to 4 inches, drilling depth of more than 50 meters wells when the economic game is: first with 8cm drill drill down to the desired water (such as 100 meters), remove the drill pipe of 40 m, installation 18cm reaming bit, then the same drill reaming depth 40 metres, then drill pipe out of all. PVC tube, with the following 68 meters long diameter 50mmPVC tube, upper with 32 meters long diameter 110mmPVC pipe can be. (the thick pipe length is less than the depth of the reaming 6-8 meters, to filter the stones to fall smoothly to the bottom) which can greatly reduce the cost. (water bearing sand General requirements for 5 - 10 meters in between, well tube permeable hole drill 4 - 8 meters, 10 cm intervals play a 12mm diameter holes, with 2-3 layer of 100 mesh sieve yarn package, the actual operation should accurate calculation, as shown in Figure:
Note; experience exchange of experience for reference, there are wells experience master can be determined according to their own experience.
Four, daily maintenance:
The motor part 1, the rig handling should be handled with care, to avoid the rain splash,
2, electric wire connector can not touch the power,
3, often check whether the replacement of wire rope,
4, the drill pipe wire head oil before and after use placed shelter to avoid rust,
5, the motor can not be a long time overload operation,
6, the motor does not turn when the inspection circuit, and the transformer insurance.
