In a preferred implementation of the present utility model, when producing sound barrier of the present utility model, two U types lifting connecting reinforcement is inserted in respectively on the steel wire net rack sandwiched plate, 1/5th places apart from two ends, and be welded on the steel wire net rack.The specification of steel wire net rack sandwiched plate is 2950 * 950 * 100mm, cut-off directly is 6mm, the reinforcing bar of length 2000mm, bent intermediate becomes the U type, and bending point width 100mm forms the wide U type lifting connecting reinforcement of 100mm, the internal diameter of bending part top welding lifting nut is 12mm, external diameter is 16mm, height 25mm, and the lifting nut bore is sealed with adhesive plaster.Brush separation layer or shelve plastic foil at mold bottom, the regeneration aggregate structural concrete of making thinner then, shelve the steel wire net rack sandwiched plate, identical apart from distance around the mould, beat four limit steel wire net rack sandwiched plates, make the regeneration aggregate structural concrete along steel wire net rack sandwiched plate four limit overflows, four limit tamping regeneration aggregate structural concretes.Pouring regeneration aggregate sound absorption concrete on the steel wire net rack filled board.Wherein, the prescription of described regeneration aggregate structural concrete layer is: cement 250kg, 0-5mm reclaimed sand 500kg, coarse aggregate 248kg in the 5-10mm regeneration, early strength admixture 2kg; Water 100kg, according to the ordinary concrete stirring technique, stirring, mixing for standby use.The prescription of described regeneration aggregate sound absorption layer of concrete is cement 150kg, 0-5mm loam brick recycled fine aggregate 250kg, and the 0-5mm regenerated foamed plastic is as waste old polystyrene foamed plastic pellet 10kg, durafiber 1kg, early strength admixture 1%; Water 100kg stirs earlier foamed plastics, fiber and 1/2nd water, adds cement, aggregate, Admixture continuous stirring again 3-5 minute, and is standby.Form removal after 3 hours enters curing kilns maintenance or natural curing.Adopt the folded method of watering once to prepare several piece sound barrier of the present utility model.The described folded method of watering is to prepare first sound barrier as stated above: brush separation layer or shelve plastic foil at mold bottom, the regeneration aggregate structural concrete of making thinner then, shelve the steel wire net rack sandwiched plate, identical apart from distance around the mould, beat four limit steel wire net rack sandwiched plates, make the regeneration aggregate structural concrete along steel wire net rack sandwiched plate four limit overflows, four limit tamping regeneration aggregate structural concretes.Pouring regeneration aggregate sound absorption concrete on the steel wire net rack filled board, on first sound barrier, shelve plastic foil then, the regeneration aggregate structural concrete of making thinner again, shelve the steel wire net rack sandwiched plate, beat four limit steel wire net rack sandwiched plates, make the regeneration aggregate structural concrete along steel wire net rack sandwiched plate four limit overflows, four limit tamping regeneration aggregate structural concretes, pouring regeneration aggregate sound absorption concrete on the steel wire net rack filled board, mode prepares 6-7 piece sound barrier according to this, form removal after 3 hours enters curing kilns maintenance or natural curing and obtains product.According to the design needs, the thickness of the regeneration aggregate structural concrete layer of sound barrier is 30-50mm, and the thickness of regeneration aggregate sound absorption layer of concrete is 50-70mm, and the thickness of the regeneration aggregate structural concrete layer around the sound barrier is 25mm.
Produce the sound barrier of the concavo-convex moulding of regeneration aggregate sound absorption layer of concrete band, on first sound barrier, shelve plastic foil, on plastic sheeting, shelve moulding mould, shelve layer of plastic film again, pour into a mould regeneration aggregate sound absorption concrete then, shelve the steel wire net rack sandwiched plate, carry out the making of second sound barrier.The regeneration aggregate sound absorption layer of concrete of two sound barriers docks with regeneration aggregate sound absorption layer of concrete, and promptly the lastblock moulding mould also is the moulding mould of next piece.
When using sound barrier of the present utility model, at first prefabricated strip foundation member or cast-in-situ steel reinforced concrete are shelved in the excavation basis, shelve prefabricated sound barrier fixed leg, are inserted in the hole that strip foundation reserves; Or the welding channel-section steel, with the welding of strip foundation pre-embedded steel slab, or the cast-in-situ concrete post.Fixed leg spacing 3020mm.By lifting nut lifting sound barrier, regeneration aggregate sound absorption layer of concrete lifts two sound barriers towards sound source between two posts then.Usually the sound barrier height is 2 meters, and 500mm height glass also can be installed in top.Form colorful speedway, high speed railway sound barrier thus.
The beneficial effect of sound barrier of the present utility model is:
(1) realizes comprehensive utilization of resources
The essence of highway, high speed railway sound barrier is exactly highway, high-speed railway enclosure wall, and what it was particular about is durable, practical. Adopt regeneration aggregate to do highway, high speed railway sound barrier, realized comprehensive utilization of resources, belong to the low-carbon economy product.
(2) give full play to the solid waste advantage
Regeneration aggregate and natural aggregate fundamental difference are the porosity height, have advantage so make the acoustics material, no matter make noise barrier structure concrete or sound absorption concrete, all are conducive to improve the sound absorbing capabilities of sound barrier.
(3) sound absorption, sound insulation property is superior
Remove regeneration aggregate and be conducive to improve outside the sound barrier sound absorbing capabilities, adopt the sound absorption concrete of regenerated foamed plastic pellet configuration, sound absorbing capabilities is good, and the folded polystyrene foam plastics of steel mesh frame sandwich further improves the sound barrier sound absorbing capabilities simultaneously.
(4) intensity is good, durable
The steel wire on three-dimensional steel wire net rack both sides is fixed sound absorption concrete slab and structural concrete plate uniformly, firmly, avoids the cracking of concrete slab.And the concrete acoustical barrier that extrusion is produced because structural concrete and sound absorption concrete material differ, intensity differs, occurs layering easily, disconnects, comes off.
(5) in light weight
A kind of regenerated aggregate concrete sound barrier, ordinary circumstance, the benzene plate accounts for sound barrier volume about 40%, adds that the sound absorption concrete is lighter, so the sound barrier in light weight 1/5th to 1/4th that a kind of regenerated aggregate concrete sound barrier is produced than extrusion.
(6) production efficiency height
Ordinary circumstance, the layer concrete five minutes of making thinner was shelved the steel wire net rack sandwiched plate five minutes, shelved separation layer two minutes, produced a sound barrier in promptly 20 minutes.Take to fold and water method, save the trouble of ordinary more mold exchange.
