step two: immediately flushing the well after the well is completed, wherein the flushing adopts a deep well submersible pump with 220V stainless steel lift of 70m and a water pump diameter of 10cm, and is provided with a generator, so that the well is flushed until water is clear, and no sediment is the standard;
step three: after the well flushing is completed, water is adopted for more than twenty four hours, a water taking pipe is a copper pipe 9, the diameter is 45mm, the length is 1m, 1.5L of water can be taken at one time, a collecting and releasing device 2 is fixed at the top end of a hollow pipe 1 through a connecting device 5 before water taking, when an inductive probe 10 touches the water surface, an indicator lamp 4 on a wellhead box 3 alarms to prompt the water surface, a connecting rope 12 is slowly released through the collecting and releasing device 2 at the moment, the copper pipe 9 slowly sinks under the action of dead weight, two unidirectional water inlet devices 7 capable of freely turning upwards are connected to the center of a counterweight metal block 8, the copper pipe 9 is opened upwards under the action of water pressure, the copper pipe 9 continuously sinks until the copper pipe 9 is filled with water along with the increase of weight of the groundwater, then the copper pipe 9 is lifted upwards, the unidirectional water inlet device 7 at the bottom of the water taking pipe is automatically closed under the action of water gravity, so that the groundwater is collected, and finally the water is poured out from the water outlet at the left upper part of the copper pipe 9.
The working flow is as follows: all electric appliances in the device are external power sources, when the device is used, a drill bit 13 is used for drilling holes into a well under a foundation, after the drill bit 13 is drilled below a water level, a hollow pipe 1 is arranged in the middle of the drill hole, sand and stones are uniformly backfilled into the drill holes around the hollow pipe 1 after the drill bit 13 is arranged in the foundation, a drilling machine is adopted by a hole forming machine according to the field environment, a DPP100-4E type automobile drill is adopted, a threaded drill bit 13 with the diameter of 240mm is arranged on the hollow pipe 1, the connecting part of the drill bit 13 is connected with the hollow pipe 1 at the bottom end through a connecting device during installation, then the drill bit 13 which is required to be used and is fixedly provided with a connecting block 602 is inserted into a fixed sleeve 601, a second threaded shaft 608 is rotated, and when a rack 607 is meshed with a fixed gear 603 at the outer side of the connecting block 602, the supporting block 605 continuously compresses the second spring 606, because the maximum torsion which can be born by different drill bits 13 is different, when the scale value of the second threaded shaft 608 on the dial 609 just reaches the maximum torsion range which can be born by the drill bits 13, the second threaded shaft 608 stops rotating, at the moment, when the drill bits 13 reach the maximum torsion, the gear 603 can continuously slide and is not clamped with the rack 607, thereby well protecting the drill bits 13, avoiding the phenomenon of fracture deformation of the drill bits 13, when the drill bits 13 are drilled below the water level, the drill bits 13 at the bottom end of the PVC hollow tube 1 are removed, the PVC hollow tube 1 is inserted into a drilled hole, underground deep water is collected, and the maximum depth can be drilled to 70m, so that the underground water collection requirement of a large-thickness loess area can be met; the hollow tubes 1 can be connected through a connecting device, when the drill bit 13 is disassembled, the drill bit 13 can be disassembled only by pulling the bottom pull rod 504 to compress the bottom first spring 505, so that the clamping block 503 at the bottom is separated from the lower sleeve 501 at the bottom, at the moment, the upper sleeve 502 at the bottom is separated from the lower sleeve 501 at the bottom, the greatest difficulty in collecting water samples in loess areas with large thickness is that after the drill bit 13 drills below the water level, loess below the groundwater level is in a soft plastic or flow plastic state due to long-time soaking of water, if no necking is performed in time, the wall protection is easy, and therefore, underground water samples cannot be collected, and the PVC hollow tube 1 with the diameter of 160mm is processed for preventing water taking failure caused by drilling necking; in order to ensure the quality and accuracy of water taking, in principle, the well depth should be 10-20 m below the water level, so that five diagonal cross holes 14 are all arranged at the end part of the PVC hollow pipe 1 below the water level, so that underground water can smoothly flow into the pipe, well flushing is immediately carried out after well logging, a deep well submersible pump 220V stainless steel lift 70m is adopted for well flushing, the diameter of a water pump is 10cm, a self-contained generator is used for well flushing, no sediment is the standard, water is taken after the well flushing is completed for more than 24 hours, a water taking pipe is a copper pipe 9, the diameter is 45mm, the length is 1m, 1.5L of water can be taken once, before water taking, a retraction mechanism is positioned at the top end of the hollow pipe 1 at the top end through a connecting device, then a first threaded shaft 203 is rotated anticlockwise, a connecting frame 202 drives a left rubber wheel 204 to move leftwards at the moment, then a connecting rope 12 is placed between two rubber wheels 204, finally, the left rubber wheel 204 is reset, after the operation is completed, the control motor 208 drives the driving gear 207 to be positively and negatively meshed with the driven gear 206, and the rubber wheel 204 can be driven to positively and negatively rotate under the drive of the fixed shaft 205, so that the copper pipe 9 is driven to move up and down through the friction between the rubber wheel 204 and the connecting rope 12, the labor intensity of workers is reduced, when the copper pipe 9 moves down to water, when the sensing probe 10 touches the water surface, the indicator lamp 4 on the wellhead box 3 alarms to prompt the water surface, the motor 208 slowly rotates, so that the connecting rope 12 is slowly controlled to move down, the copper pipe 9 slowly sinks under the action of dead weight, because the center of the counterweight metal block 8 is connected with two unidirectional water inlet mechanisms capable of freely turning upwards, the piston 702 continuously compresses the third spring 703 under the action of water pressure, so that the water inlet at the bottom end of the water inlet pipe 701 is opened, water can enter the copper pipe 9 through the water inlet pipe 701 at this time, along with the fact that groundwater continuously enters the copper pipe 9, the weight of the copper pipe 9 is increased and can continue to sink until the copper pipe 9 is filled with water, then the motor 208 is controlled to reversely rotate to lift the copper pipe 9 upwards, the piston 702 can be automatically reset and closed under the action of water gravity, accordingly groundwater is collected, and finally water taken out is poured out from a water outlet on the left side of the top end of the copper pipe 9.
