Description
Technical field
The present invention relates to the measurement mechanism of asphalt highway construction, particularly Portable asphalt compound loose laying depth, temperature-indicating instrument, can measure loose laying depth and the temperature of asphalt, especially be applicable to measuring bituminous pavement loose laying depth and the temperature that adopts paver to be constructed.
Background technology
In the construction and maintenance processes of bituminous pavement, the thickness of bituminous pavement is a very important technical indicator, will detect at any time the paving thickness on road surface in paving process, to determine whether to meet standard.In present practical operation, usually still adopt the method for traditional direct sample, on bituminous pavement, after drill rod of insertion or screwdriver, extract, then measure numeral with ruler.To measure the thickness of bituminous pavement, this measuring method not only speed is slow, and poor accuracy, pitch easily occurs in operation and scald.
Hot-mixed asphaltic concrete loose laying depth and temperature polymeter that the existing published patent No. is 201220588505.0 are the column type structure, although had than much progress, reading is not easy to read.Base is little, can't guarantee the vertical of analyzer and road surface while measuring operation.Be provided with diathermanous hole on the scale sidewall of thermometer lower end, can't directly contact with bituminous concrete, make temperature survey have error.The middle part of scale is provided with for observing the reading window of the thermometer number of degrees, and temperature reading is not directly perceived.
The patent No. is the 200820019074.X determinator for loose laying thickness of asphalt mixture, needs a hand-held rotating handles, and the another hand is pinned and pressed down handle, will bore bar and be pressed into bottom, takies both hands, inconvenient operation.Read text scale is little, is not easy reading numerical values and can't meets the demand of simultaneously measuring temperature.
Summary of the invention
The purpose of this invention is to provide Portable asphalt compound loose laying depth, temperature-indicating instrument, for asphalt pavement construction loose laying depth and temperature provide specific purpose tool, handled easily, facilitate reading of thickness and temperature, improve the precision of measuring numerical value, increase work efficiency.
Technical solution of the present invention is: Portable asphalt compound loose laying depth, temperature-indicating instrument comprise scale and base, vernier caliper is sleeved on scale, in the handle of vernier caliper, probe is installed, temperature sensor and digital display thermometer are housed on probe.
Compared with prior art, remarkable result of the present invention is: the present invention in use, probe directly is inserted in the bituminous concrete paving concrete pavement that will measure, can complete the measurement of thickness and temperature, the mounting design of vernier caliper and probe is reasonable, easy to operate, the digital display thermometer adopted is connected with temperature sensor, measure accurately, error is little, reads conveniently.The design of base and handle are with long, and the operation application of force is stable.The design of scale is according to order from small to large, to indicate from top to bottom, makes reading of asphalt loose laying depth very clear, as long as vernier pointer is alignd with the scale of scale is zero, the reading directly read after measurement is the loose laying depth of asphalt.The present invention has simple in structure, adopts stainless steel to manufacture, low cost of manufacture, durable in use, measure simple to operate, measuring accuracy is high and have advantages of detect thickness and temperature simultaneously.Not only improved the precision of work efficiency and measurement, also considered the protection to operating personnel, adopted heat insulation handle, avoided scalding, result of use is remarkable.
