ce draw handy on is it ask datum line , instrument of sensor to bear first(23mm steel wire rope), then it set up well all (from 10m),according to hanging wire that measure being the higher to confirm height , location of steel wire per of. Should measure , adjust conscientiously meticulously , check steel wire pulling force and can39。 t be smaller than 784N. Otherwise because measurement inaccurate, quantity line fault or pulling force enough steel wire it scratches to be can through erect instrument at steel wire is it get pave highway section to reflect, cause the wave form of road surface to rise and fall , influence the roughness. We have adopted the portable basic roof beam of making by oneself in storey on the ShanghaiNanjing expressway pitch constructed, the length is 10m, pave the precision and reach variance of the roughness. In order to realize the expressway of airport of Nanjing under highstandard in roughness, introduce one gram of portable basic roof beams which the Company produced then of American Bruno again. This device long , basic roof beam in front of paver equip with 2*12 can the flexible snow prized board up and down, and then can39。 t equip with roof beam not basic 2*16 piece flexible rubber wheel from head to foot,in front and at the back of roof beam not basic, at paver arm office knuckle joint not old, it can dispel by lower floor too some to level ,have road surface slope (before not passing roof beam not basic get) not vertical not original and can39。 t spread high Cheng not average of layer (after not passing roof beam not basic get ) bined newly in, pared with the situation that tightwire walking and makes the snow by oneself to prize , pave the precision to obviously improve , thus improved the roughness of road surface . The using correctly of the instrument performance of the paver and finelying tune device The control of road surface elevation is realized by the instrument. It is fullautomatic to transfer paperback edition put , can according to make level order of appearance reach and design to high Cheng automatically for paver to take, it is good to pave the roughness of road surface built like this. If the instrument reflects slowly, in addition, the finelying tune device will reflect to go up and down to paving the road surface to improperly use, influence the roughness. The paver is pressed the plateform is heated and adjusted In the ShanghaiNanjing expressway , in the highspeed construction of the highway of airport of Nanjing, we have used Germany to produce ABG422 type , ABG311 type , VOGELE2020 type , Model VOGELE1800 paver. To press dull and stereotyped heating device ABG type whether liquefied gas heat four paver these, VOGELE type is heated of electricity. Before paving , press dull and stereotyped heating temperature enough or heat even, can lead to the fact temperature high mixture and temperature pressing plateform is it marry to glue low when paving, is it pave aspect is it draw hair to appear , light hole hole , dark trough ,etc. a irregular one full of bumps and holes to make. So, press dull and stereotyped temperature and must be heated to 85176。 C90176。 C before paving. In addition, must check and press dull and stereotyped straight degree conscientiously before paving, if was joining or joined the phenomenon instead , must adjust Exactly prop up and draw and press the dull and stereotyped length of pull rod , enable pressing the plateform and making the surface and belonging to one slope together, so as to ensure the horizontal roughness of road surface . Paver vibrator, impact on roughness of road surface of rammer hammer There are very great relations between frequency and paving the speed , mixture one grade of mixing , temperature and thickness of vibrator , rammer hammer ,etc., should select suitable frequency conscientiously according to the regulation of the operation instructions . If pave layer on the a thin one, vibrator , rammer hammer frequency pass conference lead to the fact and press the dull and stereotyped resonance, make the paver look for the paperback edition to put the roughness of influence in unstable state. Meanwhile, should check vibrator , rammer hammer belt often, belt is it will is it shake frequency of smashing , tamp speed of number of times differ to make to relax overly, form the road surface washboard . It causes the road surface not to level to correct travel direction The travel direction of the paver is while happenning askewly, must correct in time . At this moment, the paver track advances on one side, another side advances slowly, quick side press dull and stereotyped ahead have first little step that redound forward, there is a small step pushed and shoved backward to press the dull and stereotyped back end on the slow side, influence the roughness of road surface, should take measures to dispel while rolling .。
