Description
Technical field
The utility model belongs to construction, repairing, repairs or removes the auxiliary equipment technical field that road or similar paving are used, and is specifically related to clean, handle or fill the equipment that the road surface of finishing and road, movement area, aerodrome face are processed of ditch, groove or seam usefulness.
Background technology
When newly-built cement concrete road and road, movement area, aerodrome face, in order to guarantee that cement concrete is unlikely to be damaged because of the physical change of expanding with heat and contract with cold under the situation of temperature Change, between a cement block and an adjacent cement block, leave the shrinkage joint, the embedded calking that is filled with in shrinkage joint.
Cement concrete road and road, movement area, aerodrome face are after using after a while, calking generation aged deterioration in the shrinkage joint, rainwater is ceaselessly invaded in the shrinkage joint, sinkage can appear in the ground on cement concrete road and airport, the supporting capacity of cement concrete road and road, movement area, aerodrome face is more and more lower, make that pit appears in cement concrete pavement and road, movement area, aerodrome face, disease such as subside, seriously influenced traffic safety and flight safety.The maintenance of cement concrete road and road, movement area, aerodrome face, very main one side is that the shrinkage joint of cement concrete pavement and road, movement area, aerodrome face is maintained in early days, in time fill up, application life and the raising supporting capacity that prolongs cement concrete road and road, movement area, aerodrome face had very important significance.
The traditional way of maintenance of cement concrete road and movement area, aerodrome pavement expansion joint is that the former calking in the shrinkage joint is cleared in the shrinkage joint, then new calking is embedded in the shrinkage joint of cement concrete road and road, movement area, aerodrome face.For this reason, designer of the present utility model had once invented " cement concrete road surface expansion joint crack-cleaning machine ", " saw-blade type cement concrete road surface expansion joint crack-cleaning machine ", these two kinds of crack-cleaning machines, compare with the old calking in the existing manual cleanup cement concrete shrinkage joint, improved speed of application, alleviated labour intensity, improved effect, shortened construction period.The cement concrete road surface expansion joint crack-cleaning machine only is equipped with a straight raked joint cutter, in the practice of construction process, width according to the cement concrete shrinkage joint is changed the raked joint cutter, incured loss through delay construction period, in carrying out the raked joint process at cement concrete shrinkage joint, because the width at cement concrete shrinkage joint does not immobilize, old calking cleaning in the cement concrete shrinkage joint is unclean, particularly the old calking on the two side can not be cleared in the cement concrete shrinkage joint, make new calking all pointing in the cement concrete shrinkage joint, have influence on the repair quality of cement concrete road and road, movement area, aerodrome face.In addition, the cement concrete road surface expansion joint crack-cleaning machine is when operation, two wheels and directive wheel are walked on cement concrete pavement, and directive wheel is walked in cement concrete road surface expansion joint very little, holding capacity is big, trailing wheel is installed under the plate that rises and falls, and makes the cement concrete road surface expansion joint crack-cleaning machine produce vibration when operation, and walking is unstable, make the raked joint cutter in the cement concrete road surface expansion joint internal vibration, easily the raked joint cutter is damaged.
