Abstract
The invention discloses a method for handling cracking of a plastic track. The cracked part of the plastic track is chiseled away, a distance of 15-20 cm is emptied, concrete below is exposed, cutting is performed along a crack, a seam which is 3-5 cm deep and 3-5 cm wide is formed and filled with an elastic material, and after the elastic material is compacted and leveled, the plastic track is repaired along left and right sides 15-20 cm away from the seam. With the adoption of the method, the surface of the cracked position of the plastic track can be integrally molded with a base material, and secondary cracking in the later period of repair can be avoided.
Description
Technical field
The invention belongs to plastic material field, be specifically related to the processing method of a kind of plastic cement race track cracking.
Background technology
Plastic cement race track paves on coagulating cement earth foundation, by the bonding effect of polyurethane glue brute force, plastic cement race track surface layer and concrete foundation are bonded to an entirety, plastic cement race track surface layer in expansion joint position and concrete foundation are also bond firmly, like this, if done not in accordance with the requirement of correct construction method, once temperature reduces, concrete certainly leads to contraction and causes shrinkage joint to expand, plastic cement race track surface layer on shrinkage joint and concrete bonding firm, plastic coat does not have enough stretching distances, be difficult to bear huge pulling force and produce fracture.(such as: the gap width under the reset condition of shrinkage joint is 5mm, the stretchable distance of plastic cement race track surface layer is also 5mm, temperature reduces shrinkage joint and shrinks and cause shrinkage joint to expand 5mm, such expansion joint width just becomes 10mm, plastic cement race track surface layer synchronously needs the length stretched to be the words of 5mm, now the elongation at break of vapor-permeable type plastic cement race track is 100%, considerably beyond >=40% physical performance index.Can't bear the heavy load and rupture.Refer to elongation at break method of testing and calculating formula: elongation at break method of testing is, in the effective stretching distance of 50mm, carry out tension test, vapor-permeable type plastic cement result of the test requires that >=40% is qualified.Elongation at break design formulas: elongation at break=(distance after stretching-effectively stretching distance)/effectively stretching distance.But according to on-site actual situations, effective stretching distance is only 5mm, breaking rear distance is 10mm, according to design formulas, and elongation at break=(10-5)/5=100%.）
After there is cracking in plastic cement race track, traditional processing method is cut in the place of cracking, forms " V " font that 1cm is wide, then in " V " font, fill gap-filling glue, such way decreases the secondary cracking of plastic cement race track in a sense, but effect not obvious.
Summary of the invention
The object of the present invention is to provide the processing method that a kind of plastic cement race track ftractures, surface, plastic cement race track cracking place can be made one-body molded with base material, avoid the secondary cracking repairing the later stage.
For achieving the above object, the present invention adopts following technical scheme:
A kind of processing method of plastic cement race track cracking: the plastic cement race track that cracking is local cuts, vacate the distance of 15-20cm, expose concrete below, cut along its crack, form the ditch seam of a dark 3-5cm, wide 3-5cm, filling elastic material wherein, after compacting is clapped, then the distance extending 15-20cm along ditch seam left and right carries out the repairing of plastic cement race track.
Described elastomeric material is that black rubber particle and elastic gum mix by weight for 5-7:1.
Described black rubber particle is made up of waste tire rubber.
Described elastic gum is weight ratio is the polyurethane of 1:2-4 and the mixed glue solution of ethylene propylene diene rubber.
Remarkable advantage of the present invention is: method of the present invention can make surface, plastic cement race track cracking place one-body molded with base material, avoids the secondary cracking repairing the later stage.
