The concentric type mounting structure is contained in a drilling hole and comprises a water outlet pipe, a water level detecting pipe, a submerged pump, a water level communicating device, a water level probe, a water level detecting rope and a water returning pipe. The submerged pump is arranged on the bottom of the water outlet pipe. The water level detecting pipe is contained in the water outlet pipe. The water level detecting pipe and the water outlet pipe are arranged coaxially. The water level detecting pipe is communicated with the drilling hole through the water level communicating device. The water level probe is contained in the water level detecting pipe. The water level detecting rope is connected to the water level probe. The water outlet pipe is connected with the water returning pipe through a water outlet tee joint. One end of the water returning pipe extends into the drilling hole. According to the concentric type mounting structure of the water pumping test pipeline, the water level detecting pipe and the water outlet pipe are arranged coaxially, so that the opening diameter of the drilling hole is obviously reduced, drilling workload of a large-diameter water well is lowered, drilling efficiency is improved, and drilling cost is lowered.
Description
[technical field]
The utility model relates to a kind of hydrogeologic prospecting equipment, is specifically related to a kind of concentric type mounting structure of pumping test pipeline, belongs to the geological prospecting equipment technical field.
[background technology]
Along with the fast development of World Economics, both at home and abroad the demand of various mineral resources increased sharply, increasing mine transfers underground mining to by strip mining transformation gradually.Mining area hydrogeologic prospecting task is more and more.The construction of underground mining mine, vertical shaft is corresponding increase also, corresponding the increasing of prospecting task of mine, vertical shaft.No matter be hydrogeologic prospecting, or the prospecting of mine, vertical shaft, all requires to carry out probing work, carry out hydrogeological test in holing.
Pumping test is one of main measure of hydrogeological test.Pumping test need to be installed suitable pumping equipment and necessary pipeline.The position, deep that pumping equipment is lowered to is the pump position.Aperture, to the bore diameter of hole, the darkest pump position section, is to be determined by maximum outside diameter and the instrument of gauge observation of pumping equipment and the drilling process such as geological conditions, hole depth, retaining wall leaking-stopping measure, sleeve pipe bore of holing.Therefore, pumping equipment and pipeline installation form are directly determining the design of Geology Drilling structure, such as the size of perforate bore, wall casing, filter pipe etc.And the boring caliber size has directly determined the complexity of a series of drilling technologies such as required drilling equipment type, drilling process, retaining wall measure to affect drilling efficiency and drilling cost.Aperture is larger, and core-drilling efficiency is lower, and drilling cost is just higher.
Yet the survey water level pipe of the pumping test of prior art and outlet pipe adopt the scheme be arranged in juxtaposition, and can not meet the requirement of drawing water of small diameter hole.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of concentric type mounting structure with structure improved pumping test pipeline, to overcome described defect of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of can reduce the perforate bore of holing, and improves drilling efficiency, reduces the concentric type mounting structure of the pumping test pipeline of boring cost.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of concentric type mounting structure of pumping test pipeline, it is contained in a boring, and it comprises outlet pipe, surveys water level pipe, submersible pump, water level linker, water-level probe, water level lining rope and return pipe; Wherein, described submersible pump is arranged at the bottom of outlet pipe; Described survey water level pipe is contained in outlet pipe, and both are coaxial the setting; Described survey water level pipe is communicated with described boring by described water level linker; Described water-level probe is contained in to be surveyed in water level pipe, and the water level lining rope is connected on water-level probe; Described outlet pipe is connected with return pipe by an outlet three way; One end of described return pipe extends in boring.
The concentric type mounting structure of pumping test pipeline of the present utility model further is set to: in described return pipe, be provided with a backwater valve.
The concentric type mounting structure of pumping test pipeline of the present utility model also is set to: the side in described outlet three way is connected with a water discharging valve.
Compared with prior art, the utlity model has following beneficial effect: the concentric type mounting structure of pumping test pipeline of the present utility model is by installing outlet pipe and survey water level pipe concentric type, perforate bore like this can significantly reduce to hole, reduce heavy caliber well probing workload, improve drilling efficiency, reduce drilling cost.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the concentric type mounting structure of pumping test pipeline of the present utility model.
[specific embodiment]
Refer to shown in Figure of description 1, the concentric type mounting structure that the utility model is a kind of pumping test pipeline, it is contained in a boring 9, and it is comprised of several parts such as outlet pipe 1, survey water level pipe 2, submersible pump 3, water level linker 4, water-level probe 5, water level lining rope 6 and return pipes 7.
Wherein, described submersible pump 3 is arranged at the bottom of outlet pipe 1.
Described survey water level pipe 2 is contained in outlet pipe 1, and both are coaxial the setting.This survey water level pipe 2 is communicated with described boring 9 by described water level linker 4, and the water in its boring 9 are freely introduced and surveyed in water level pipe 2, makes outlet pipe 1 inwall and survey water level pipe 2 outer walls form exhalant canal 10 ring-type, sealing simultaneously.Survey the interior water surface of water level pipe 2 and all be communicated with atmosphere with the boring 9 interior waters surface, make to survey the interior water level of water level pipe 2 identical with boring 9 interior water levels.
Described water-level probe 5 is contained in to be surveyed in water level pipe 2, and water level lining rope 6 is connected on water-level probe 5, and described water-level probe 5 and water-level probe 5 coordinate the water level detected in boring 9.
Described outlet pipe 1 is connected with return pipe 7 by an outlet three way 8.A side in described outlet three way 8 is connected with a water discharging valve 81.
One end of described return pipe 7 extends in boring 9, which is provided with a backwater valve 71.
The design principle of the concentric type mounting structure of pumping test pipeline of the present utility model is as follows: while drawing water, the High-Pressure Water that submersible pump 3 work produce rises through exhalant canal 10, outlet three way 8 shuntings through earth's surface; Surveying water level pipe 2 upper ends stretches out from outlet three way 8; High-Pressure Water, through outlet three way 8 shuntings, enters earth's surface triangular-notch weir case (not shown).When boring 9 water yields hour, the variable partition water yield flow back in boring 9 by return pipe 7, the manual control drawdown.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making within all spirit in this creation and principle, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
