Description
Technical field
The utility model relates to Geotechnical Engineering fields, and in particular to a kind of for the side-mounted curved of geotechnical centrifuge model
The sealing structure of Qu Yuan.
Background technique
In geotechnical engineering geotechnical centrifuge model, it is frequently utilized that the velocity of wave of flexure element device to test soil sample, to obtain soil sample
Maximum shear modulus under the conditions of small strain.But flexure element is mounted on the axis direction in triaxial chamber along sample more, can only survey
Determine the velocity of wave of soil sample in the axial direction；And in Practical Project, undisturbed soil sample is often anisotropic, horizontal direction and vertical
Mechanical characteristic significant difference, this just needs also measure the velocity of wave of soil sample in the horizontal direction in geotechnical centrifuge model simultaneously, comes
Obtain its horizontal direction maximum shear modulus.
Currently, having developed miniature side-mounted flexure element in geotechnical centrifuge model, soil sample can be measured along its level side
To velocity of wave.But most of geotechnical centrifuge models need to apply confining pressure using water, since bender element is to water quite sensitive,
It is easily destroyed, the waterproof problem in triaxial chamber after lateral flexure element insertion soil sample just becomes intractable problem.
Summary of the invention
The purpose of the utility model is to provide a kind of reasonable in design, install convenient, operation are simple, waterproof side-mounted
The sealing structure of flexure element.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of sealing structure of side-mounted flexure element, including latex film, the pressure cap of latex film upper end, latex film lower end bottom
Seat and it is wrapped in latex film, pressure cap, the soil sample in pedestal, the symmetrical cut hole in latex film two sides, flexure element can penetrate cutting for latex film
Hole is contacted with soil sample, and the cut hole of the latex film wears rubber earrings, and rubber earrings flange is close to latex film inner wall, and flexure element is worn
Enter rubber earrings, the rubber earrings on the outside of O-ring lock ring latex film.
Further, the rubber earrings and latex film joint are sealed using sealant.
Further, the contact surface for stating rubber earrings and flexure element is coated with silica gel.
Further, the rubber earrings internal diameter is 1mm bigger than flexure element outer diameter.
Further, it offsets on the outside of the O-ring and latex film.
Further, the cut hole aperture of the latex film is 1 ~ 5mm.
The utility model compared with prior art, has the advantage that
A kind of sealing structure of side-mounted flexure element of the utility model, reasonable in design, install convenient, operation are simple.
While side-mounted flexure element is to soil sample horizontal direction wave velocity testing under the conditions of realizing three axis, has the effect of waterproof.
Detailed description of the invention

Fig. 2 is a kind of rubber ear-ring structure schematic diagram of the sealing structure of side-mounted flexure element of the utility model.
Fig. 3 is a kind of rubber earrings schematic cross-section of the sealing structure of side-mounted flexure element of the utility model.
Specific embodiment
With reference to the accompanying drawing, the embodiments of the present invention are described in further detail.
As shown in Figure 1, a kind of sealing structure of side-mounted flexure element, including latex film 2,2 upper end of latex film pressure cap 1,
The pedestal 8 of 2 lower end of latex film and it is wrapped in latex film 2, pressure cap 1, the soil sample 3 in pedestal 8.The symmetrical cut hole in 2 two sides of latex film, cuts
Kong Shi, with thumb and index finger will latex film 2 pull out a little after cut an osculum, as close as possible to being cut at finger, the relaxation metapore of latex film 2
Easily become larger, aperture is usually no more than 5mm.In cut hole on latex film 2, guarantee that two hole location fronts are opposite, with soil sample axle center one
It rises, 3 points are located on same level axis, to ensure the flexure element 6 after installing in the same level vertical with soil sample central axes
On face.
The cut hole of the latex film 2 wears rubber earrings 4, the flange of rubber earrings 4 when penetrating the hole location of latex film 2,
Rubber earrings 4 is squeezed into finger tip needle-shaped, finger unclamped after the hole location of latex film 2, rubber earrings 4 restores former automatically
Shape, 4 flange of rubber earrings are close to 2 inner wall of latex film, rubber earrings 4 and 2 joint of latex film and are sealed using sealant, guarantee to connect
It is water-tight to close position.As shown in Figure 2,3, the flange of rubber earrings 4 is band ear one end of rubber earrings 4.Rubber earrings 4 has one
Fixed elasticity after extrusion deformation, can automatically restore to reset condition.
The flexure element 6 penetrates rubber earrings 4 and contacts with soil sample, and the internal diameter of rubber earrings 4 is bigger than the outer diameter of flexure element 6
The piezoelectric ceramic wafer 7 of 1mm, flexure element 6 are contacted with soil sample.It, need to be outside flexure element 6 when flexure element 6 is pushed into rubber earrings 4
Surface and 4 inner wall of rubber earrings smear appropriate silica gel, to guarantee that flexure element 6 smoothly in push-in rubber earrings 4, plays waterproof
Effect.
The rubber earrings 4 in 5 lock ring latex film of O-ring, 2 outside.Before flexure element 6 is pushed into rubber earrings 4, needing first will be O-shaped
Circle 5 passes through on the cable of flexure element 6；After flexure element 6 is pushed into rubber earrings 4, then by 5 sets of O-ring at 4, rubber earrings
Portion is pressed on latex film 2, plays the role of waterproof.
The above is only the preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
Personnel can also make several improvements and modifications without departing from the concept of the premise utility, these improvements and modifications
It should be regarded as in scope of protection of the utility model.
