Technical field
The utility model relates to pavement detection equipment technical fields, and in particular to a kind of intelligence pavement benkelman beams deflectometer.
Background technique
Flexure is one of the important technology index of Road Design and highway engineering quality status evaluation, it reflects on the whole
The integral strength of each level in road surface, the intensity of roadbed are generally reflected with the modulus of resilience.If deflection value is excessive, deformation
Bigger, each layer in road surface is also easy for rupturing.Deflection value is excessive, material properties of the reason generally with each layer in road surface, and thickness is whole
Body is related.
Deflection value refers under the effect of defined standard axle load, total vertical change that roadbed or road surface wheel gap position generate
Shape (total flexure) rebounds vertically deformation values (rebound deflection), as unit of 0.01 mm.Usually said rebound deflection value is
The quasi- rear axle of index carries the maximum rebound deflection value at two-wheel group wheel gap center.General pavement benkelman beams deflectometer is also backman beam.It adopts
Made of lever principle, road surface can be deformed under the action of car load, and vehicle restores to the original state after leaving, measurement standard
When the automobile of axis weight passes through road, the vertical deformation or rebounds upon deformation value that wheel position generates can show the rigid of road surface
Degree and bearing capacity.Deformation measured directly is known as total flexure, and deformed springback capacity is rebound deflection.
Current Beckman beam type benkelman beams deflectometer generally using mechanical dial gauge, needs a dial gauge in use
Bracket, and lever tail also needs to install a high bar after benkelman beams deflectometer, dial gauge measuring rod is pressed against on high bar and is measured,
Dial indicator bracket will be reapposed when causing to measure every time, and the high bar of lever tail after benkelman beams deflectometer is installed, is virtually increased
The volume of benkelman beams deflectometer, it is all one section of public affairs by manually being read, being recorded in measurement process that it is more inconvenient, which to use and carry,
Road will measure multiple points, heavy workload, and artificial reading easily mistake occurs, has an impact to the accuracy of entire measurement result.
Urgently proposing that one kind does not need indicator bracket, volume is smaller, and using more convenient, it is able to achieve and automatically records reading, and
The intelligent benkelman beams deflectometer uploaded by electronic information equipment.
