Description
Technical field
The invention belongs to road basement material test unit technical field, be specifically related to the pick-up unit of a kind of concrete infiltration.
Technical background
Along with the progress and development of social civilization, road net is expanded rapidly, the volume of traffic also increases in geometry multiple, especially the phenomenon that transfinites of the overload of vehicle in freight transportation is serious, when constantly extruding road, make pavement damage, especially high class pavement is in the process of constantly extruding, if concrete material infiltration, basic unit is then very easily caused to be intake, and aggravate the destruction of roadbed, it combines with purt mud phenomenon, because the vehicle of heavier mass is under the effect of load in vehicle travel process, roll there being the road surface of water and produce high-strength current, wash away roadbed top layer, partial material is departed from overall, produce gap and then lower roadbed to be emptied constantly rolling, accelerate the infringement to highway structure, therefore need to propose higher construction criteria to the construction of roadbed.
At present, seep water less to verify the highway subgrade of design whether can withstand extruding or how much extrude and the impermeable time, main employing leaves standstill infiltration and osmosis both at home and abroad, thus weigh the infiltration capacity of experiment material, but its majority situation not that is virtually reality like reality, otherwise too idealized, too harsh, make the data of acquisition true not, and real road is due to the continuous extruding of automobile, exacerbates the infiltration capacity of water.
A kind of road material washout tester is disclosed in CN201876409U, by well heater, main water box, recovery tank, gear case, backwater cover, mair motor, water pump, slide block connecting rod, nozzle rotary support, slide block, revolving shaft, guide rail, inductive switch, protective cover, nozzle, test specimen, piece fixture and electrical control cabinet composition, in main water box, well heater is installed, top is provided with gear case, mair motor is by the side-to-side movement on guide rail of toggle band movable slider, the rotatable nozzle of angle is fixed with on slide block, the piece fixture internal fixtion test material on nozzle opposite.First the water under high pressure that pump motor can regulate from nozzle ejection pressure is started, slide block side-to-side movement on guide rail when mair motor operates continuously, drive and repeatedly wash away in surface of test piece from the water under high pressure of nozzle ejection, the pressure water that real simulated roadway roadbed is suffered in actual environment wash away situation.
A kind of road material washout tester is disclosed in documents CN201876409U, by well heater, main water box, recovery tank, gear case, backwater cover, mair motor, water pump, slide block connecting rod, nozzle rotary support, slide block, revolving shaft, guide rail, inductive switch, protective cover, nozzle, test specimen, piece fixture and electrical control cabinet composition, in main water box, well heater is installed, top is provided with gear case, mair motor is by the side-to-side movement on guide rail of toggle band movable slider, the rotatable nozzle of angle is fixed with on slide block, the piece fixture internal fixtion test material on nozzle opposite.First start the water under high pressure that pump motor can regulate from nozzle ejection pressure, slide block side-to-side movement on guide rail when mair motor operates continuously, drive and repeatedly wash away in surface of test piece from the water under high pressure of nozzle ejection; Although it serves certain realistic simulation, but during its inreal simulated automotive rolling road surface, High-Pressure Water is produced owing to rolling in the gap when extruding road surface, road surface, pressurize under making current direction, thus accelerate to enter in concrete, and the current of this device are only on surface, therefore its data measured are still true not, and its complex structure, therefore need a kind of can real simulation concrete road reaction True Data test unit.
Summary of the invention
