Four, description of drawings
Accompanying drawing is a structure chart of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
Shown in accompanying drawing, one end of the utility model cable 1 is connected with data acquisition unit 2 by aviation plug, the other end of cable 1 and pressure sensor 8 upper ends are tightly connected, pressure sensor is put into test section, long-range sender water meter 5 is connected on the packer permeability test pipeline, an end that is contained in the flow transmitter 4 on the long-range sender water meter 5 is connected on the data acquisition unit 2, and data acquisition unit 2 is connected with computer data treatment system 3, and is connected with pressure sensor 8, flow transmitter 4.
In said structure, wherein pressure transducer functionality is: when carrying out packer permeability test, fluid pressure is converted to the output of standard electric signal and sends data acquisition unit to; The function of flow transmitter is: measure the flow size in the packer permeability test, convert the standard electric signal to, and send data acquisition unit to; The function of data acquisition unit is: data acquisition is to gather the various data that pressure capsule system, flow sensing system send on request, converts the signal of computer identification to and is transported to notebook computer; The function of data handling system is: receive the experimental data of collector transmission, show process of the test on request, carry out the data processing, store, print, check test achievement etc. realize the automation that test data sheet data and data are handled.
Easy to carry in order to guarantee result of use and use, said flow transmitter 4 is the tongue tube sensor; One end of said flow transmitter 4 is connected with data acquisition unit 2 by aviation plug; Said data acquisition unit 2 is linked to each other with the notebook computer data handling system by the usb data line; Said data handling system 3 is to adopt the LabVIEW language compilation, at Windows XP, and Vista system support operation down; Said long-range sender water meter 5 is contained on the water pipe of the hydrostatic test pipeline that links to each other with drilling rod 6 tops, and pressure sensor 8 places the lower boreholes 9 packer permeability test sections 10 of the sealing embolism 7 on the drilling rod 6.
Working condition of the present utility model is, after the test section drillman finishes, set about the preparation of plant and instrument and inspection → test pipeline connection → underground water level measurement → test apparatus connection → pressure zero setting → turn on pump pressure testing, pipeline inspection → five-spot packer permeability test → (after the off-test) experimental data is preserved and printout → pipeline release, termination of pumping → program are withdrawed from, line disconnection → pipeline is removed.
Useful technique effect of the present utility model is:
(1) solved the technical barrier that dried deep hole can't carry out conventional packer permeability test
Conventional packer permeability test is: common water meter is used in flow observation, pressure observation working pressure table, and water meter and pressure meter are arranged in the aperture ground surface.When underground depth to water during more than or equal to 30m, this moment, conventional packer permeability test can not carry out the test of 0.3MPa stage or all the other several stages, because of the water column of minimum existing 30m (〉=0.3MPa) act in the examination section, and place the pressure meter on the face of land can't show the water column pressure that acts on the examination section.The setting-out comprehensive tester then is the pressure of directly measuring on the examination section, is not subjected to the influence of groundwater level depth.
(2) solved the numerous and diverse and coarse technical barrier of packer permeability test Calculation of pressure loss
Water-pressurizing test method commonly used at present is that water meter, pressure meter are arranged in the aperture ground surface.Water can not be used gauge measurement along the pressure loss in the passage stream during test, needs to solve by calculating, and the calculating of current pressure loss has two big problems: the one, and the problem of cycle calculations; The 2nd, the pressure loss of different tests equipment differs greatly, and need survey one by one, and its workload is too big and numerous and diverse, and operability is not strong.The setting-out comprehensive tester then is the pressure of directly measuring on the examination section, is not subjected to the influence of groundwater level depth.

(4) reduce field construction labour intensity and construction cost greatly
Use in this system, the test operation personnel can reduce 60%, and also can reduce more than 50% labour hour, reduced labour intensity and construction cost.
(5) automation, the informationization of packer permeability test have been realized
From collection, record, the DATA PROCESSING of data and calculate achievement and preserve or printout, all can finish automatically by test procedure, data information is preserved convenient, but and resource-sharing.
(6) simple operation, applicability is good
The installation of this tester is easy with the use operating process, and reuse is good; Being convenient to field worker uses.The formation of this system is succinct simultaneously, and the level of integrated system height has taken into full account the influence of field extreme environment in the design, and instrument quality is good, and compliance is strong.
(7) technological achievement is advanced practical, and systematic function is reliable and stable
Use by the test in the object of construction production repeatedly, as be successfully applied to " ten days river power station, Shaanxi prospecting engineering ", " river mouth, Henan village key water control project prospecting engineering ", " the ditch reservoir leak stopping of Jincheng, Shanxi tin precipice with reinforce the prospecting engineering " and " the ancient virtuous key water control project in the Yellow River is reconnoitred engineering ", especially in the Gu Xian building site 200 surplus the test of a hole section use, instrument performance is reliable and stable, the data record repdocutbility is good, the validity height can satisfy the requirement of test accuracy fully.Solve the dried deep hole packer permeability test of long-term puzzlement water conservancy industry well and realized the technical barrier of record, automatic data processing automatically, realized the new breakthrough of water conservancy and hydropower water pressure test in borehole measuring technology.
