Description
Technical field
The utility model relates to a kind of measuring apparatus, specifically a kind of analyzer of bituminous concrete loose laying depth.
Background technology
According to the regulation of " highway quality detection standard ", the thickness of asphalt concrete pavement is a very important technical indicator.In order to ensure the thickness of flexible pavement, in bituminous concrete paving process, need the loose laying depth detecting compound at any time, to determine whether to meet standard.At present, in construction process of asphalt pavement, measuring the survey tool that bituminous concrete loose laying depth extensively adopts is: screwdriver or reinforcing bar and steel ruler.Screwdriver or reinforcing bar are inserted making layer, extracts rear steel ruler and measure loose laying depth.This method for measuring thickness poor accuracy and survey crew be mixed material scald in measuring process easily.
The patent No. 200820019074.X determinator for loose laying thickness of asphalt mixture now announced, needs a hand rotating handles during measurement, the subordinate pressure handle hand of another, inconvenient operation; Its cone bar is conical design in addition, being easily mistakenly inserted in lower floor's compound when inserting bottom, causing the phenomenon that reading and actual value are not inconsistent.
Patent No. 201320082660.X modified flexible pavement thickness measurement instrument, the design of its balance bracket cannot ensure the verticality requirement of depression bar in measuring process, the design of other three contact pins also constrains its limit and fathoms, and oversize contact pin is more fragile again.
Utility model content
The purpose of this utility model is, a kind of thickness measurement equipment measured for road asphalt rigid pavement surface construction medium pitch concrete loose laying depth is provided, structure is simple, cost of production is low, it is convenient, fast to measure, certainty of measurement is high, adopt the utility model can improve operating efficiency and the precision of survey crew, and then improve construction quality.
The technical scheme adopted is:
A kind of bituminous concrete determinator for loose laying thickness, comprises insulating rubber handle, cylindrical scale with a scale and sleeve, it is characterized in that:
Insulating rubber handle is fixedly connected with the upper end of cylindrical scale with a scale.The lower end of cylindrical scale with a scale is fixedly connected with insertion plate, and the lower end of inserting plate is wedge shape, and cylindrical scale outer wall with a scale axially offers direction recess.Sleeve lining is axially arranged with guide ledges, sleeve bottom is connected with circular base plate, and circular base plate center offers and the rectangular opening inserted plate width and match, and inserting plate can stretch out rectangular opening, there is jackscrew screw sleeve upper end, is installed with jackscrew in jackscrew screw.Insert plate to be made up of stainless steel.
Lower end and the insertion plate of cylindrical scale with a scale are plugged in sleeve, and the guide ledges on sleeve lining is positioned at the direction recess on cylindrical scale outer wall, is slidably matched.Screwing jackscrew makes cylindrical scale locate.
Above-mentioned rectangular opening edge is fixed with hairbrush.
Scale zero on cylindrical scale is alignd with edge on sleeve.
Rule from top to bottom, the descending arrangement of scale.
When measuring bituminous mixture loose laying depth, the utility model is placed on concrete surface to be measured by surveying work personnel, unclamp screwing screw, under push away insulating rubber handle, insertion plate is pushed in concrete, tightening screwing screw when arriving concrete layer, extracting the utility model, from cylindrical bar scale, directly read the loose laying depth numerical value of bituminous mixture.Apply this utility model and measure asphalt mixture paving course thickness, simple to operate, quick, reading is directly perceived, accurate, avoids the potential safety hazard of measurement simultaneously.Owing to aliging with the scale zero on cylindrical scale in edge on sleeve by the utility model in design, therefore can use without the need to zero during double measurement, not existing and not producing error because of not making zero.
Rectangular aperture place, chassis arranges hairbrush, for clearing up in test process the fine aggregate being bonded at and inserting on plate.
Remarkable result of the present utility model is adopted to be: the utility model in use, vertically be placed on the position that will measure, press down handle and thickness measuring plate is inserted in the bituminous mixture that will measure, fastening tightening screw, read the numerical value on rule, the measurement of loose laying depth can be completed.Insert plate and be designed to plat ruler type shape, widen the contact width with compound bottom, in the surveying work of reality, certainty of measurement is high, error is little.Chassis is circular, can steadily be placed on measuring point and not tilt, and ensures the verticality on thickness measuring bar and road surface.Circular base plate center has only by inserting the through hole of plate, and the surrounding in hole is stained with hairbrush, and removing adheres to the fine aggregate inserted on plate.Sleeve being arranged tightening screw and fix thickness measuring scale, preventing from producing measure error because sliding.It is simple that the utility model has structure, reasonable in design, and operation uses quick, and reading is directly perceived, and measurement result is accurate, is easy to processing, is easy to carry, the advantage that cost is low.
