Description
Technical field
The present invention 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 guarantee the thickness of flexible pavement, in bituminous concrete paving process, need to detect at any time the loose laying depth of compound, to determine whether to meet standard.At present, in construction process of asphalt pavement, the survey tool of measuring the extensive employing of bituminous concrete loose laying depth is: screwdriver or reinforcing bar and steel ruler.Screwdriver or reinforcing bar are inserted to making layer, extract and with steel ruler, measure loose laying depth afterwards.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 of now having 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, and easily bottom inserting, mistiming is inserted in lower floor's compound, the phenomenon that causes reading and actual value not to be inconsistent.
Patent No. 201320082660.X modified flexible pavement thickness measurement instrument, the design of its balance bracket cannot guarantee the verticality requirement of depression bar in measuring process, the design of other three contact pins has also restricted its limit and has fathomed, and oversize contact pin is more fragile again.
Summary of the invention
The object of the invention is, a kind of thickness measurement equipment of measuring for road asphalt rigid pavement surface construction medium pitch concrete loose laying depth is provided, simple in structure, cost of production is low, it is convenient, fast to measure, certainty of measurement is high, adopt the present invention can improve operating efficiency and the precision of survey crew, and then improve construction quality.
The technical scheme adopting is:
A bituminous concrete determinator for loose laying thickness, comprises heat insulation rubber handle, with cylindrical scale and the sleeve of scale, it is characterized in that:
Heat insulation rubber handle is fixedly connected with the upper end of cylindrical scale with scale.Lower end with the cylindrical scale of scale is fixedly connected with inserting plate, and the lower end of inserting plate is wedge shape, on the cylindrical scale outer wall with scale, axially offers direction recess.On sleeve lining, be axially arranged with guide ledges, sleeve bottom is connected with circular base plate, and circular base plate center offers and the rectangular opening of inserting plate width and matching, and inserts plate and can stretch out rectangular opening, there is jackscrew screw sleeve upper end, in jackscrew screw, is installed with jackscrew.Inserting plate is made by stainless steel.
With the lower end of the cylindrical scale of scale and insert plate and be plugged in sleeve, the guide ledges on sleeve lining is positioned at the direction recess on cylindrical scale outer wall, is slidably matched.Screw jackscrew and make cylindrical scale location.
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.
While measuring bituminous mixture loose laying depth, surveying work personnel are placed on the present invention on concrete surface to be measured, unclamp screwing screw, under push away heat insulation rubber handle, insertion plate is pushed in concrete, when arriving concrete lower floor, tighten screwing screw, extract the present invention, from cylindrical bar scale, directly read the loose laying depth numerical value of bituminous mixture.Apply this invention and measure bituminous mixture layer thickness of mating formation, simple to operate, quick, reading is directly perceived, accurately, avoided the potential safety hazard of measuring simultaneously.Due to the present invention in design by sleeve along aliging with the scale zero on cylindrical scale, so without making zero, can use during double measurement, do not exist because do not make zero and produce error.
Rectangular aperture place, chassis arranges hairbrush, for clearing up test process, is bonded at the fine aggregate inserting on plate.
Adopt remarkable result of the present invention to be: the present invention 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, the fastening screw that screws, read the numerical value on rule, can complete the measurement of loose laying depth.Insert plate and be designed to plat ruler type shape, widen the contact width with compound bottom, in actual surveying work, certainty of measurement is high, error is little.Chassis is circular, can steadily be placed on measuring point and not tilt, and guarantees the verticality on thickness measuring bar and road surface.Circular base plate center only has can be by inserting the through hole of plate, and the surrounding in hole is stained with hairbrush, removes and adhere to the fine aggregate inserting on plate.On sleeve, arrange and screw fixedly thickness measuring scale of screw, prevent from producing because sliding measure error.The present invention has simple in structure, reasonable in design, and operation is used quick, and reading is directly perceived, and measurement result is accurate, is easy to processing, be easy to carry, and the advantage that cost is low.
