Abstract
The utility model provides a volumetric strain measuring device capable of eliminating influence of bubbles. The device comprises a water inlet pipe (1), a bubble interception box (2), a water outlet pipe (3) and a volumetric strain pipe (4) which are connected successively. The bubbles move upwards to the top of the bubble interception box after entering the bubble interception box along the water inlet pipe, and water whose volume equals that of the bubbles is discharged out of the water outlet pipe at the other end of the bubble interception box, thereby ensuring the volumetric strain pipe represents the real water discharge, and ensuring measuring accuracy.
Description
Technical field
The utility model belongs to Geotechnical Engineering testing equipment technical field, and particularly a kind of body of eliminating aeration becomes measurement mechanism.
Background technology
In Geotechnical Engineering field, in order to obtain the basic physico-mechanical properties parameter of the soil body, usually need to carry out experimental study in associated chamber; Except measuring stress and axial strain, bulk strain is also very important data.For saturated sample, the water discharge of sample in process of the test is cubic deformation amount, so only need Measurement accuracy sample water discharge.Cubic deformation amount conventionally adopts body to become pipe and measures, and body becomes pipe and is connected by drainpipe with sample; But, many times because drainpipe is long or plastic tube internal diameter is less, the residual a lot of bubbles of meeting in drainpipe, the bad discharge of these bubbles is even difficult to drain, after on-test, the stressed and then moisture content of sample is discharged, and residual bubble also becomes pipe motion to body thereupon, become the contact of Guan Houyu air when bubble enters body, cause measuring error.
Utility model content
Utility model object: in order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of body of eliminating aeration to become measurement mechanism.
Technical scheme: a kind of body of eliminating aeration that the utility model provides becomes measurement mechanism, comprises that water inlet pipe, the bubble of connection successively held back box, rising pipe and body change pipe.
As improvement, described water inlet pipe is held back box bottom with rising pipe respectively at bubble and is connected.
Improve as another kind, it is transparent box that described bubble is held back box, so that can the interior liquid level situation of observation box.
Improve as another kind, described bubble is held back box top and is provided with venting valve.
Improve as another kind, described water inlet pipe and rising pipe are respectively equipped with valve.
Improve as another kind, also comprise hydraulic pressure sensor, described hydraulic pressure sensor is located at rising pipe and body becomes between pipe.
Beneficial effect: the body of the aeration eliminated that the utility model provides becomes measurement mechanism and holds back box by bubble is set, when bubble enters and holds back after box along water inlet pipe, bubble will up move to bubble and hold back box top, now holding back the other one end of box water pipe with the water body of bubble equal volume from bubble discharges, guarantee still to represent real water discharge in body change pipe, thereby ensured that the volume of measuring is accurate.
Particularly, all must the discharge plastic drain-pipe of effort before on-test in the past in bubble, the long or caliber of drainpipe hour even may not discharged bubble.But, utilize equipment of the present utility model, can not need waste of manpower to remove to discharge bubble; Can eliminate residual bubble in drainpipe completely and body be become to the impact of measuring; If bubble is more, in process of the test, also can utilize the hole of holding back box top that gas is discharged.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model can be eliminated the body change measurement mechanism of aeration.
Fig. 2 is the structural representation that bubble is held back box; Wherein, Fig. 2 (a) holds back front view, the 2(b of box for bubble) bubble holds back the vertical view of box.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
The body that can eliminate aeration becomes measurement mechanism, sees Fig. 1 and Fig. 2, comprises that water inlet pipe 1, the bubble of connection successively held back box 2, rising pipe 3, hydraulic pressure sensor 6, body change pipe 4; Described water inlet pipe 1 is held back box 2 bottoms with rising pipe 3 respectively at bubble and is connected; Described bubble is held back box 2 tops and is provided with venting valve 5; Described water inlet pipe 1 and rising pipe 3 are respectively equipped with valve; Described bubble is held back box 2 for organic glass box.
The using method of this device is as follows:
(1) before test, install sample, open bubble and hold back the venting valve 5 of box 2, inject distilled water, after filling, (bubble hold back in box 2 cannot see obvious bubble) closes venting valve 5.
(2) in test, draining outward after sample is stressed, if having bubble in water inlet pipe 1, bubble can be followed water and is moved into together bubble and hold back in box 2 and up move to bubble and hold back box 1 top.Now, and the water body of bubble equal volume holds back box 2 from bubble and is expelled to rising pipe 3, and therefore body becomes in pipe 4 and still reflects real water discharge.
(3), if the interior bubble of water inlet pipe 1 is more, bubble enters bubble and holds back the rear generation of box 2 and gather; When bubble is too much, still likely hold back the outlet discharge of box 2 from bubble.Disposal route: hold back the interior bubble of box 2 when more when bubble, close bubble and hold back box 2 two ends valves, turn on bubble and hold back the venting valve 5 of box 2, inject distilled water, after filling, (hold back in box cannot see obvious bubble) closes venting valve 5.
Claims (6)
1. the body that can eliminate aeration becomes a measurement mechanism, it is characterized in that: the water inlet pipe (1), the bubble that comprise connection are successively held back box (2), rising pipe (3) and body change pipe (4).
2. a kind of body of eliminating aeration according to claim 1 becomes measurement mechanism, it is characterized in that: described water inlet pipe (1) is held back box (2) bottom with rising pipe (3) respectively at bubble and is connected.
