Description
Technical field
The utility model relates to a kind of full-automatic roadbed material antiscour test unit, particularly relates to a kind of cement stabilized type, lime stabilization class, lime-flyash stabilization class stabilized with inorganic binder basic unit scour resistance proving installation.
Background technology
It is vehicular load and rainwater effect that current China sub-surface destroys principal element, particularly sub-surface semi-rigid material, enter roadbed semi-rigid material at water causes base material to destroy because Vehicle Load produces high pressure flowing pressure simultaneously, highway engineering stabilized with inorganic binder material test code proposes material antiscour test method, but the method price is high, can not abundant this field of widespread use, the designed, designed development of current more unit is applicable to antiscour equipment needed for our unit, causes evaluating scour resistance index different.
Can rapid and accurate determination stabilized with inorganic binder material erosion resistibility in order to a kind of full-automatic roadbed material antiscour test unit can be developed, comprehensive evaluation stabilized with inorganic binder Anti brushing Performance has significance more.
Summary of the invention
For achieving the above object, the present invention adopts following technical proposals:
The utility model object is to provide a kind of full-automatic roadbed material antiscour test unit, a set of shaking table is set below this test unit, shaking table frequency range is between 0-10kHz, adjust shaking table Oscillation Amplitude by regulating frequency, change flow rate of water flow size simulated flow and test specimen is washed away.
In the middle of shaking table, arrange a diameter is 14cm circular hole, in circular hole, arrange a diameter is the cylindrical steel drum of 14cm, cylindrical steel drum is connected with Hydrauservo System charger by oil feed line, loaded by computer program hydraulic control servo-drive system, a rigidity is set at cylindrical steel drum top and washes away bucket, rigidity washes away barrel base and shaking table is bolted, wash away a barrel bottom surface in rigidity and fix a truncated cone-shaped base, base top arranges a big groove, big groove inherence arranges a little groove of right cylinder, two vertical steel pipes are set in shaking table both sides, steel pipe bottom is fixed on shaking table pedestal, top is connected by crossbeam, crossbeam is as test reaction frame for loading.
Big groove outside dimension is diameter 12.2cm, be highly 0.4cm, little groove size is diameter 10.2cm, be highly 0.3cm, in little groove surrounding, four test specimen enhancing hooks are evenly set for test specimen weight weighing, in groove, place geotextile prevent water movement from causing test specimen mass change to test specimen bottom friction, on geotextile, place test specimen, realize screw rod by steel pipe top end floor beam to move up and down, adopt screw rod fixation clip.
Four circular holes are set in relevant position, pressing plate top, lifting is carried out to little groove weigh by arranging four steel wires, a set of electronic weighing instrument is set at pressing plate end face and weighs for test specimen.
Arrange two steel pipes in shaking table both sides, steel pipe bottom is fixed on shaking table pedestal, and top is rigidly connected by crossbeam, and crossbeam is as test reaction frame for loading.
Patent advantage of the present invention and effect are:
1. this device is compared with antiscour equipment in the past, does not need test specimen repeatedly to take out to test, and by washing away quality of materials to washing away the replacement of weighing of rear test specimen, avoiding and precipitating washing away material, dry, shortening test period.
2. weighing system, washing away bucket by arranging four steel wires lifting rigidity, indirectly weighing to washing away rear test specimen at every turn, simple and efficient.
3. strength test, by fixing test specimen top, to rigidity wash away bottom of the barrel be loaded on test specimen destroy determine test piece intensity.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated, a kind of full-automatic roadbed material antiscour test unit, comprise a set of shaking table 1, shaking table frequency range is between 0-10kHz, shaking table Oscillation Amplitude is adjusted by regulating frequency, change the direction of a stream of water and test specimen washed away in advance, surface of test piece not to be bondd or discrete particles washes away.To make a strength test with group test test specimen, be designated as P.
Test specimen 5 being placed in rigidity washes away in bucket 6, bottom of the barrel drainpipe 4 is washed away in closedown, wash away in bucket 6 to rigidity and be filled to surface of test piece, Vibration on Start-up platform switch, two minutes are washed away in advance to test specimen, then open draining valve 4 to be got rid of by sewage and wash away bucket, in bucket, particle is all drained by water filling, carries out lifting and weighs by arranging four steel wires, 7 pairs of truncated cone-shaped bases 3 and be designated as M.
Test specimen is fallen to original position, water filling in bucket, starts shaking table and carry out washing away five minutes, by sewage discharge, refill clear water will wash away particle discharge wash away bucket and unlocking electronic scale elevator system 13, employing electronic scales 10 carry out weighing M
1.
Repeat to wash away, weigh and be designated as M
2, M
3after carry out scouring intensity test, start Hydrauservo System charger 2, by Hydrauservo System, truncated cone-shaped base 3 is loaded, top pressing plate 8 is fixed by spiral 9, open Hydrauservo System 2 to pressurize, loaded by computerized control system 12 proof stress or strain, intensity is P
0.
Scour resistance assessment parameters is antiscour coefficient and residual strength percent.
