Description

A kind of easy device for the single dicyclo water penetration test in scene
Technical field
The utility model relates to earthwork engineering testing tool technical field, is specifically related to a kind of easy device for the single dicyclo water penetration test in scene.
Background technology
On-the-spot single dicyclo water penetration test is the water percolating capacity of the soil body within the vertical upper unit interval in order to test in inner ring, and the head in outer shroud only plays a part as inner ring builds vertical seepage field.Existing measuring technology mainly contains following two kinds: first method directly uses the graduated cylinder of a constant volume to water filling in inner ring and outer shroud, by the time stops to inner ring water filling after official hour, and records the remaining water yield in the number of times of water filling and graduated cylinder.This method needs two people ceaselessly to water filling in single dicyclo, when recording the remaining water yield in graduated cylinder, certain time interval is had to inner ring water filling, and when soil property is the larger sandy soil of infiltration coefficient, there will be the phenomenon having little time water filling in ring, let alone maintain head to stablize, in this way have much room for improvement.Second method adopts existing infiltration experimental provision, same problem is there is in this device with the first test method, when soil body osmotic coefficient is large, be not easy to continue to the reading read when inner ring water filling on water yield scale in bottom, and when in water bottle during moisturizing bottom still in continuation to inner ring water filling, so the water percolating capacity of the unit interval finally obtained is inevitable less than normal.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of easy device for the single dicyclo water penetration test in scene, this apparatus structure is simple, easy to use, on-the-spot single dicyclo water penetration test can be advantageously applied to, can the water percolating capacity of the Measurement accuracy soil body within the vertical upper unit interval.
Realizing the technical scheme that the utility model above-mentioned purpose adopts is:
A kind of easy device for the single dicyclo water penetration test in scene, comprise seeping container, the water pipe of support and band valve, seeping container comprises transparent bucket and conical hopper, on bucket, the equal opening in lower end, the lower end of bucket is communicated with the large port of conical hopper, be communicated with the portlet of conical hopper with the water pipe of valve, support comprises a fixed frame and three supporting legs, article three, supporting leg is fixed on fixed frame by dismountable mode, fixed frame is fixed on the junction of bucket and conical hopper, bucket lateral wall is vertically provided with scale mark, maximum scale is arranged on bucket upper edge, zero graduation is arranged at above fixed frame.
Article three, the mode that supporting leg is threaded connection is fixed on fixed frame.
Described bucket and the material of conical hopper are hard transparent plastic, and the material of water pipe is tygon.
Compared with prior art, its beneficial effect and advantage are the utility model:
1) support of this device is detachable, installs and easy to carry, is conducive to carrying out water penetration test in the wild.
2) this device both can ensure that the injecting process was uninterrupted, directly can read water injection rate again, not only easy to operate, and can the water percolating capacity of the Measurement accuracy soil body within the vertical upper unit interval.
3) this apparatus structure is simple, cheap, can be applicable widely.
Accompanying drawing explanation
The structural representation of the easy device for the single dicyclo water penetration test in scene that Fig. 1 provides for the utility model.
Wherein, 1-bucket, 2-conical hopper, 3-fixed frame, 4-supporting leg, 5-water pipe, 6-valve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
The structure of the easy device for the single dicyclo water penetration test in scene that the utility model provides as shown in Figure 1, this device comprises the water pipe of seeping container, support and band valve, seeping container comprises transparent bucket and conical hopper, the equal opening of bucket upper and lower end, the lower end of bucket is communicated with the large port of conical hopper.Bucket and conical hopper are hard transparent plastic, not only light but also be not easy fragmentation, distortion, are applicable to be carried to field condition and test.
Support comprises a fixed frame and three supporting legs, and the mode that three supporting legs are threaded connection is fixed on fixed frame, and fixed frame is fixed on the junction of bucket and conical hopper.Because single dicyclo water penetration test is generally carry out in the wild, so this removable support is easy to carry.And support is by water bucker rack overhead certain altitude, thus provide certain water-head, be conducive to water delivery in ring.
Be communicated with the portlet of conical hopper with the water pipe of valve, the material of water pipe is tygon, adopts plastic flexible pipe.Valve and water pipe together constitute the water flow control mechanism of whole device, are controlled the speed of water filling in ring by control valve.Plastics sebific duct needs go-no-go, otherwise when plastic cement mouth of pipe footpath is too little, runs into the soil body that infiltration coefficient is large, even if valve is all opened, can not maintain stable level in ring; When plastic cement mouth of pipe footpath is enough thick, runs into any soil body, water velocity can be controlled by control valve.
Bucket lateral wall is vertically provided with scale mark, and maximum scale is arranged on bucket upper edge, and zero graduation is arranged at above fixed frame.Zero graduation is arranged at the top of fixed frame, is convenient to the change observing bucket middle water level.In the present embodiment, the range of scale mark is 5L.
The test method of the easy device for the single dicyclo water penetration test in scene that the utility model provides is as follows:
1) get this easy device A of three covers, B, C, after closing the valve of three these easy device A of cover, B, C, in the bucket of three easy device A, B, C, fill water.
2) valve of easy device A, C is opened in timing while starting, and makes the water pipe of easy device A to water filling in inner ring, and the water pipe of easy device C, to water filling in outer shroud, regulates the valve of easy device A, C, the water level of inner and outer ring is maintained on same water level.Can continuous water filling in the bucket of easy device C in experimentation, must not record water injection rate.
3) if the infiltration coefficient of soil is less, when the gap count time then, when the water level of easy device A bucket does not drop to zero graduation line, then close the valve of easy device A, open the valve of easy device B, by the water pipe of easy device B to water filling in inner ring, and record the water level of the bucket of easy device A, in the bucket having recorded backward easy device A, fill water; If the infiltration coefficient of soil is larger, do not arrive the gap count time, the water level of easy device A bucket has dropped to zero graduation line, then open the valve of easy device B while closing the valve of easy device A, continue to water filling in inner ring, and the water of the bucket of easy device A is filled again.The like, the water alter least-squares inner ring in the bucket of easy device A, B, and record water injection rate, and the water in the bucket of easy device C injects outer shroud, must not record water injection rate, only need maintain outer shroud head and stablize.
