Description
Technical field
The utility model is related to a kind of infiltration test device of testing pits in the fields such as geological mapping, water conservancy and hydropower, particularly one
Plant infiltration test of testing pits and automatically control tape deck.
Background technology
At present, in traditional infiltration test operation of testing pits, either monocyclic or bicyclic infiltration test, is all to use people
Work is operated, using light instruments such as scale, Mario buckets, in optional test position, is dug a circle and is tested pits to desired depth,
Place monocyclic or bicyclic, toward water filling in iron hoop during experiment, water-column in control ring.Injection flow measurement is proceeded by, it is for seep
Stream is stable and continues certain time, and aeration zone coefficient of permeability K is calculated according to formula.Experiment uses artificial observation, experiment essence
Degree cannot be guaranteed, and manpower wastes larger.
Utility model content
In order to overcome the shortcomings of existing infiltration test device of testing pits, it is automatic that the utility model provides one kind infiltration test of testing pits
Control tape deck.
The utility model solves the technical scheme that its technical problem used：
Infiltration test of testing pits automatically controls tape deck, including, including, recording instrument without paper, water inlet pipe, outlet pipe, flow
Sensor, ball-cock assembly and ball float；Described ball-cock assembly connects water inlet pipe and outlet pipe respectively, and ball-cock assembly is connected with for water level control
The ball float of system；Described outlet pipe is provided with flow sensor, and described flow sensor connects recording instrument without paper by cable,
Recording instrument without paper and flow sensor are connected with dc source, and described water inlet pipe is connected with water tank or feed pipe.
The utility model has an advantageous effect in that：The head height of testing pits of setting, flow are accurately controlled using ball-cock assembly
Sensor accurately measures water-carrying capacity, and the automatic record data of recording instrument without paper can simultaneously be backed up simultaneously, realize infiltration test of testing pits
The automation of journey, test data it is accurate reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Parts and numbering in figure：
1- recording instrument without paper；2- water inlet pipes；3- outlet pipes：4- flow sensors；5- ball-cock assemblys；6- ball floats.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, infiltration test of testing pits automatically controls tape deck, including, recording instrument without paper 1, water inlet pipe 2, water outlet
Pipe 3, flow sensor 4, ball-cock assembly 5 and ball float 6；Described ball-cock assembly 5 connects water inlet pipe 2 and outlet pipe 3, ball-cock assembly 5 respectively
It is connected with the ball float 6 for water level control；Described outlet pipe 3 is provided with flow sensor 4, and described flow sensor 4 leads to
Cable connection recording instrument without paper 1 is crossed, recording instrument without paper 1 and flow sensor 4 are connected with dc source, and described water inlet pipe 2 connects
It is connected to water tank or feed pipe.
Implementation process：Monocyclic infiltration test, in optional test position, digs a circle and tests pits to desired depth, place
It is monocyclic, recording instrument without paper 1, water inlet pipe 2, outlet pipe 3, flow sensor 4 and ball-cock assembly 5 are connected, and ball float 6 is adjusted to set
Fixed height of water level, toward water filling in iron hoop during experiment, the water column outside control iron hoop and in iron hoop is held at sustained height all the time,
Keep depth of water 10cm.Inner ring injection flow is proceeded by by flow sensor 4 to measure, after after seepage stability and to continue 2-4 small
When, the water penetrated into the unit interval from hole bottom, divided by hole floor space are obtained, that is, draws Mean velocity of seepage.
Bicyclic infiltration test, in optional test position, digs a circle and tests pits to estimated depth, test pits bottom side again
The water filling for digging a depth 15-20cm is tested pits, and cheats bottom equating, and ensures that the structure for testing soil layer is not disturbed.By outer annular diameter
0.5m, annular diameters 0.25m double iron hoops cheat bottom, deeply about 5-8cm by concentric circles press-in, and on inner and outer ring experimental field layer
It is even to spread the thick sand gravel layers of 2cm.During experiment, two sets of ball-cock assemblys 5 are set, outer shroud is consistent with the setting height of ball float 6 of inner ring, toward iron
The water column of water filling in ring, control outer shroud and inner ring is held at sustained height all the time, keeps depth of water 10cm.Flow sensor 4 enters
Row inner ring injection flow is measured, and after after seepage stability and continuing certain time, is injected data on flows according to inner ring, is utilized formula meter
Calculate the infiltration coefficient for determining experiment stratum.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technology of the utility model
The spirit and scope of scheme.
