Description
Technical field: the utility model relates to a kind of road engineering and detects test unit, particularly road surface base layer material proving installation.
Background technology: existing road surface base layer material test instrument, these two kinds in representative is rotating brush test instrument and shaketalle test instrument, but its weak point is all respectively arranged, and the former changes wire brush to test specimen surface polish-brush with executing, at all can't the actual situation that washed away by water of simulated roadway; The latter places water container with test specimen, and container places on the shaking platform and tests, and just simulates the influence on ripples road pavement test specimen surface, compare with washing away of under traffic load, being produced of actual road surface, souring too a little less than.
Summary of the invention:
The purpose of this utility model is to design a kind of Simulated Water more truly is subjected to the souring of road pavement material under the load situation on the road surface test instrument, it comprises the combined action of load and water road pavement, and the effect of water also comprises the influence that water washes away and aspirate the dynamic pressure of two aspects.
Technical solution of the present utility model is a kind of ground surface material washout test machine, mainly place water container by test specimen, water container is installed on the test platform and constitutes, test specimen connects with load maintainer, load maintainer is an eccentric wheel lever pressure exerting arrangement, and it is the lever stage casing mat fulcrum hinged securement by the L shaped support arm of an end band, and the L shaped support arm end of lever connects pressure plate, be set with back-moving spring on the L shaped support arm, the lever other end connects with eccentric wheel; Pressure plate and the crimping of test specimen plane between pressure plate and the test specimen, are bonded with rubber slab on the crimp surface of pressure plate, have the water scour trough on the rubber slab.L shaped support arm connects an end of pressure plate, along central axis one running-deep-hole is arranged, and counterbore one end is communicated with pressure plate and arrives at the rubber slab face, and counterbore sidewall mat skirt connects with pressure vacuum gauge.
Description of drawings:
Fig. 1 is the structural representation of ground surface material washout test machine
Fig. 2 is the water scour trough structural representation on the rubber slab
Embodiment:
The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:
A kind of ground surface material washout test machine, by placing test specimen [1] in the water tank [3] of sealing, test specimen [1] places on water tank [3] inner bottom surface, fills certain water yield in the water tank and buries test specimen [1], and water tank places on the test platform; Test specimen [1] connects with load maintainer, load maintainer is an eccentric wheel lever pressure exerting arrangement, it is to have lever [5] some mat bearings in stage casing [6] hinged securement of L shaped support arm [8] on the cover plate of water tank [3] by an end, L shaped support arm [8] end of lever [5] connects pressure plate [4], be set with back-moving spring [7] on the L shaped support arm [8], lever [5] other end connects with eccentric wheel [9], and it connects for touching, and eccentric wheel [9] is by motor drives; Pressure plate [4] and test specimen [1] plane crimping, between pressure plate [4] and the test specimen [1], on the crimp surface of pressure plate [4], be bonded with rubber slab [2], have water scour trough [13] on the rubber slab [2], water scour trough [13] be 4 along the mutual rectangular groove of cross-distribution in vertical direction of plate face.Be distributed in pressing plate [4] and exert pressure in district's scope, referring to Fig. 2, dotted line is depicted as pressure plate [4] the district A that exerts pressure.
L shaped support arm [8] connects an end of pressure plate [4], along central axis one running-deep-hole [10] is arranged, and counterbore [10] one ends are communicated with pressure plate [4] and arrive at rubber slab [2] face, and counterbore [10] sidewall mat skirt [12] connects with pressure vacuum gauge [11].
Eccentric wheel [9] and lever [5] but also the mat pivot pin is hinged, can cancel the back-moving spring [7] that L shaped support arm [8] is gone up suit.
Principle of work of the present utility model is: direct motor drive eccentric wheel [9] rotation, drive lever [5] through pressure plate [4] mat rubber slab [2] repeated stock loading of exerting pressure to test specimen [1], road surface base layer material loaded state when passing through with this simulating vehicle, plastoelastic rubber slab [2] is used to simulate the roadbed surface layer, 4 water scour troughs [13] simulated roadway crack on the rubber slab [2], when pressure plate [4] repeatedly during punching press roadbed test specimen [1], produce hydraulic pressure at both interfaces, because rubber slab [2] compressive deformation in short-term, be present in the higher flowing pressure of the water of test specimen [1] and rubber slab [2] interlayer and the water generates in the water scour trough [13] to test specimen [1] formation wash away; When eccentric wheel [9] drives the lever unloading, back-moving spring [7] makes rubber slab [4] release, recover original state, the flowing pressure vanishing that exists during pressurized, in this flowing pressure change procedure, test specimen [1] is sucked into the water of rubber slab [2] interlayer, has caused the swabbing action of water to the test specimen surface, eccentric wheel [9] revolution moves a week, just realizes once the cyclic process of washing away, aspirating to loading, unloading and the water of test specimen.
The utility model has the advantage of: testing machine had both been simulated the loading of vehicle road pavement basic unit and had been exerted pressure, and had simulated again Water road pavement basic unit forms repeatedly washing away of flowing pressure road pavement basic unit generation and aspirates institute and cause under load Impact, reflected more truly the comprehensive function of car load and water road pavement basic unit.
