Description
Technical field
The utility model relates to a kind of experimental rigs more particularly to a kind of for testing bituminous pavement limit drained strength
Device.
Background technique
During development of new bituminous pavement, need to test the properties of Cost of New Type Asphalt Pavement, wherein
More important test item is exactly permeance property test；According to the existing theory, for the drip for having certain drainability
For green road surface, if rainfall intensity is less than the drainability of bituminous pavement, the rainwater for penetrating into bituminous pavement can be drained in time,
Bituminous pavement surface is not in overland flow, if rainfall intensity is greater than the drainability of bituminous pavement, penetrates into bituminous pavement
The hole of bituminous pavement can be gradually stuffed entirely with by rainwater, finally will lead to bituminous pavement surface and overland flow occur；Surface diameter
Stream can impact traffic safety, and bituminous pavement drainability is stronger, more can not generate table under the conditions of larger rainfall intensity
Face diameter stream, therefore, it is necessary to which the limit drained strength to bituminous pavement is tested, and existing test device can not be to drip
The limit drained strength on green road surface is tested.
Utility model content
For the problems in background technique, the utility model proposes one kind for testing bituminous pavement limit drained strength
Device, improvement be: described device includes water tank, cover board, support plate, flowmeter, multimeter, two conductive rods, water pumps
And shower；
The water tank upper end opening, cover board cover the opening of water tank；Rotating stand, two are provided on cover board upper side
Root screw rod and support frame；One end of the support plate downside axial direction and rotating stand are rotatablely connected, the rotational plane of support plate
With horizontal plane；Two screw rods are located at the two sides of support plate transverse direction, and adjusting nut, adjusting nut position are provided on screw rod
In the downside of support plate, the rotary motion trace and adjusting nut of support plate are interfered；Multiple limits are provided on the upper side of support plate
Protrusion, the enclosed region of multiple retention beads form installing zone, and bituminous pavement test specimen is placed in installing zone；The water pump setting exists
In water tank；The upper end of support frame as described above is provided with extension, and the outer end of extension is located above support plate, shower and extension
The water inlet of outer end connection, shower is connected by the water outlet of pipeline and water pump；The support of socket on the support frame in the middle part of pipeline
In hole；The flowmeter is arranged on pipeline at the position of shower；Tune is provided on pipeline between flowmeter and water pump
Save valve；The conductive rod is arranged on the upper side of bituminous pavement test specimen, and two conductive rods are mutually isolated；Two conductive rod difference
It is connected on two detection terminals of multimeter by two conducting wires；Multiple through-holes are provided on the cover board.
The principles of the present invention are: water is stored in water tank；Before test, first produces size and matched with installing zone size
Bituminous pavement test specimen, then by adjusting nut adjust support plate tilt angle, after tilt angle regulates, by asphalt road
Interview part is placed in installing zone (retention bead can block bituminous pavement test specimen, prevent bituminous pavement test specimen from sliding), then will
Conductive rod is arranged in bituminous pavement surface of test piece, at this point, two conductive rods can not be connected since two conductive rods are mutually isolated,
Then starting multimeter and water pump, the water in water tank is pumped into pipeline and flows out from shower by water pump, so that rainfall is simulated, flower
The water for spilling outflow is flowed back into water tank by the through-hole on cover board；By adjusting valve regulation uninterrupted, it is gradually increased flow,
When flow increases to a certain extent, bituminous pavement surface of test piece just will appear runoff, and after runoff occurs, two conductive rods will
It is connected by runoff, can accurately determine whether runoff has formed according to general-purpose meter reading, at this point, just according to meter readings
It can determine that corresponding data on flows；Then flow-reduction to runoff is made to disappear (even if two conductive rods can not be led by regulating valve
It is logical), then so that flow is increased to runoff by regulating valve and occurs and obtain corresponding data on flows, by repeatedly testing, energy
It obtains going out current moment corresponding accurate data on flows with runoff, after converting to data on flows, corresponding drop can be obtained
Raininess degree, so that it is determined that the limit drained strength of corresponding bituminous pavement test specimen out；
When it is implemented, in order to simulate the truth of bituminous pavement, it can according to the actual situation, (such as with sealing material
Paraffin) some sides of bituminous pavement test specimen are sealed, ooze out water can only from the particular side of bituminous pavement test specimen.
Preferably, the multimeter is arranged on the support frame.
The advantageous effects of the utility model are: proposing a kind of for testing the dress of bituminous pavement limit drained strength
It sets, which can be measured the limit drained strength of bituminous pavement test specimen.
