4) pavement construction is few to ambient influnence.Traditional pavement construction needs more construction machinery, produces larger noise during construction machinery operation.Meanwhile, in traditional pavement engineering construction, waste material of buildings is more, comprises water conservancy, timber, packaging material, discarded mould etc.These refuses are buried under the ground, and can cause the pollution of underground water.The utility model is prefabricated at workshop, and refuse is less and can focus on, on the almost not impact of job site environment.
5) spread i.e. use, open to traffic early.Once laying construction is complete, just open to traffic immediately after removal suspension ring.Even can be open to traffic on construction limit, limit, be conducive to conveniently marching into the arena of construction machinery and Construction traffic, accelerating construction progress.The time that is open to traffic after construction of cement concrete road surface is greater than 16 days, and the time that is open to traffic after asphalt concrete pavement construction is greater than 3 days, and the bridge-type prefabricated reinforced concrete trough slab pavement system that the utility model adopts can spread i.e. use, and even limit paving is just used.
6) dismounting freely.Bridge-type prefabricated reinforced concrete trough slab pavement system is reusable, can lay in advance, is transported to when needed on-the-spot laying.Built-in fitting is housed in structure, installs, removal suspension ring are very convenient, structure hoisting fashionable dress upper lift ring is Liftable.
7) technique is simple, and cost is lower, and bridge-type prefabricated reinforced concrete trough slab pavement system adopts ordinary reinforced concrete as preparing material, and the cost of material is low, and structure is unified standard size, Mold Making and build all very convenient.
8) applied widely.Bridge-type prefabricated reinforced concrete trough slab pavement system is applicable to have the various roadbeds of certain bearing capacity, can not only be used in the laying of construction with interim matter transportation road, can also be used for rushing to repair the road being damaged in earthquake.
9) road slab surface arranges steel fibre surface layer, has improved abrasion resistance and the crack resistance of road surface, thereby has improved the application life on road surface.
10) use of L-type rubber pad, can reduce the vibration of vehicle to basis and roadbed, improves the application life on road surface.
The utility model can be widely used in the quick reparation of temporary pavement construction or road.
