Embodiment 1

[0029] Such as Figure 1-3 As shown, the implementation area of ​​the present invention is close to the Taklimakan Desert and belongs to the Tarim River Basin. This area is dry and rainless, with little precipitation and large evaporation. , the specific operation is as follows:

[0030] c), start to drill wells, drill holes from the ground with soil borrowing tubes, and drill wells to the depth of the submerged layer;

[0031] d) On the basis of step c, align the wellbore and erect the triangular bracket, align the pulley hook of the tripod bracket with the center of the wellbore, hook the upper end of the casing with the pulley hook of the tripod bracket, and align the center of the wellbore with the ground Put vertically into the casing;

[0032] e) Use the soil auger to drill the sediment in the casing, and the casing gradually descends as the sediment is taken out. In order to ensure that the soil auger can take soil vertically, it needs to be pulled by the pulley hook ...

Embodiment 2

[0036] The implementation area of ​​the present invention belongs to the lower reaches of the Tarim River Basin. This area is dry and rainless, with little precipitation and large evaporation. The site conditions are sandy loam, the shallow groundwater level is 13 meters to 22 meters, and 3 wells are drilled. The specific operations are carried out according to the following steps :

[0037] c. Start to drill the well, and drill the hole from the ground with the soil borrowing tube, and drill the well to the depth of the submerged layer;

[0038] d. On the basis of step a, align the wellbore and set up the triangular support. The pulley hook of the tripod is aligned with the center of the wellbore. Use the pulley hook of the tripod to hook the upper end of the casing, and align the center of the wellbore to be perpendicular to the ground. into the casing;

[0039] e. Use the soil auger to drill the sand in the casing. As the sand is taken out, the casing gradually descends. I...

Embodiment 3

[0043] The implementation area of ​​the present invention is in the transitional zone between oasis and desert, drought and little rain, less precipitation, large evaporation, site conditions are sandy loam and loam, shallow groundwater level 19 meters to 29 meters, 6 wells are drilled, and the specific operations are as follows conduct:

[0044] c. Start to drill the well, and drill the hole from the ground with the soil borrowing tube, and drill the well to the depth of the submerged layer;

[0045] d. On the basis of step a, align the wellbore and set up the triangular support. The pulley hook of the tripod is aligned with the center of the wellbore. Use the pulley hook of the tripod to hook the upper end of the casing, and align the center of the wellbore to be perpendicular to the ground. into the casing;

[0046] e. Use the soil auger to drill the sand in the casing. As the sand is taken out, the casing gradually descends. In order to ensure that the soil auger can take s...

Abstract

The invention discloses a rapid casing pipe type well digging device. The device comprises a support, a soil auger, an oil taking barrel, a small water pump, a water injection pipe, a casing pipe, a water seepage pipe and a silt sucking water pipe or a water sucking pipe. A rapid casing pipe well digging method comprises the steps that in a dry and sandy area sandy land or a windy desert area or a sandy land, the soil taking barrel is used for punching a hole in a phreatic layer, a pulley hook of the support is aligned to the center of a well hole and hooks the upper end of the casing pipe, the casing pipe is placed into the well hole, the soil auger is used for drilling and taking silt in the casing pipe or the silt sucking water pipe and the water injection pipe are inserted to the bottom of the casing pipe for sucking silt, the casing pipe gradually descends along with taking-out of the silt, a pulley hook rope of the support is used for pulling the top of the casing pipe to descend until reaching the place nearby the underground water line, the water seepage pipe is inserted into the bottom of the casing pipe, then a pulley of the support is used for lifting out the casing pipe, the water seepage pipe deeply penetrates into the underground water containing layer, the water sucking pipe is inserted into the internal area of the water seepage pipe, the upper portion of the water sucking pipe is fixedly connected with the small water pump, and rapid casting pipe type well digging work is completed.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation, and relates to casing rapid drilling equipment and a method. Background technique [0002] The sand barren land or aeolian area or sandy area in the arid and aeolian region of Xinjiang is widely distributed, and the transition zone between the edge of the oasis and the desert in the two major basins—the Junggar Basin and the Tarim Basin—belongs to the sand barren land or aeolian area. The area is dry and rainless, and the villages, towns, and herdsmen’s settlements are densely distributed, but the available surface water resources are limited. For a long time, it has been difficult for people and animals to drink water and garden economic water in this area. It is imperative to use shallow groundwater technology or water-saving and efficiency-enhancing technology. . [0003] In order to solve the problem of drinking water for humans and animals in the region, the Xinjiang Uygur A...
