The invention discloses a device and method for real-time continuous measurement of thickness of an uncompacted layer spread by an asphalt spreader. The device comprises a hollow horizontal reference surface measuring tube, a horizontal reference surface height range finder, a hollow spread-thickness measuring tube, a spread-thickness range finder and a horizontal reference surface measurement liquid container. According to the invention, the problem that real-time measurement cannot be performed in the asphalt spreading process is solved, a dynamic actual thickness of the uncompacted layer during spreading of a whole road is provided, labor intensity and error rate are reduced, and in the process of real-time measurement, the horizontal reference surface height tube (i.e. the horizontal reference surface measuring tube) directly reflects the non-spread pavement condition, so that influences from terrain and other measurement conditions are avoided.
Description
Technical field
The present invention relates to a kind of asphalt paver virtual resurfacing thickness measurement mechanism and method.
Background technology
In the build process of flexible pavement, the virtual resurfacing thickness of asphalt paving is an important indicator of quality control, and the measurement of virtual resurfacing thickness at present mainly relies on and draws the mode of reference line and paver pressing plate height sensor to measure.
The mode of drawing reference line is to determine and draw an altitude datum line according to the design elevation of making layer on the sub-layer surface of making, height according to reference line when making paves, the laying of reference line must be very meticulous, and its length is advisable with 150～200m, and long degree of tension is difficult to guarantee.Bracing wire should adopt wire rope, and tightening force is not less than 1000N, should have superposition section more than 1m at two segment base directrix joining places, after levelling sensor slips over superposition section, could remove old line.Due to this method process of deployment in waste time and energy and easily make mistakes, therefore reduced the speed and the quality that pave.
Paver iron board position sensor is measured the height of iron board, but the width of roadway of making is wider, due to screed Stiffness, lateral pickup accuracy of measurement reduces, and, position sensor can only be measured the adjustable height of iron board hoisting mechanism, in the time of the situation out-of-flatness of the road surface of surfacing not, cannot effectively measure the true virtual resurfacing thickness paving.
Summary of the invention
Measure inconvenient technical problem in order to solve current paver virtual resurfacing thickness, the invention provides and a kind ofly can facilitate asphalt paver virtual resurfacing thickness measurement mechanism and the method for measuring accurately virtual resurfacing thickness.
In order to realize above-mentioned technical purpose, technical scheme of the present invention is, a kind of asphalt paver virtual resurfacing thickness measurement mechanism, comprise the level reference measuring tube of hollow, level reference height rangefinder, the paving thickness measuring tube of hollow, paving thickness rangefinder and horizontal reference planar survey liquid container, in described measurement liquid container, be filled with measurement liquid, described level reference measuring tube is connected by pipeline the bottom of measuring liquid container respectively with the bottom of paving thickness measuring tube, described level reference height rangefinder is fixed on the top of level reference measuring tube to measure the liquid level of liquid apart from the distance at level reference measuring tube top in measurement level reference measuring tube, described paving thickness rangefinder is fixed on the top of paving thickness measuring tube to measure the liquid level of liquid apart from the distance at paving thickness measuring tube top in measurement paving thickness measuring tube, level reference measuring tube, all there is opening at the top of paving thickness measuring tube and measurement liquid container to communicate with outside atmosphere, level reference measuring tube is identical with the length of paving thickness measuring tube.
Described device, connects by flexible pipe between described level reference measuring tube, paving thickness measuring tube and measurement liquid container.
Described device, described level reference measuring tube is arranged on the ground not paving before paver and with paver and moves, and described paving thickness measuring tube is arranged in the iron board of paver.
The method of utilizing described measurement device asphalt paver virtual resurfacing thickness, comprises the following steps:
Step 1: inject and measure liquid so that be all filled with horizontal reference planar survey liquid in level reference measuring tube, paving thickness measuring tube and measurement liquid container to measuring in liquid container;
Step 2: level reference measuring tube is arranged on the ground not paving before paver, move and mobile with paver, paving thickness measuring tube is arranged in the iron board of paver, and level reference height stadia surveying goes out in level reference measuring tube to measure the liquid level of liquid apart from the distance H at level reference measuring tube top
