Bridge-type prefabricated reinforced concrete trough slab wear resistant road surface structural system of the present invention, lays with traditional road and compared with method for maintaining, has structural strength high, and be convenient to transport, reusable, the advantages such as high construction efficiency, are in particular in the following aspects:
1) convenient transportation.Although structure is built by steel concrete, the volume of each block is little, and is standardized structural element, transports more convenient.
2) Fast Installation, easy construction.Structure upper is provided with built-in fitting, make the installing of bridge-type prefabricated reinforced concrete trough slab pavement system hoisting ring and removal very convenient, and then make the lifting of this bridge-type prefabricated reinforced concrete trough slab pavement system very convenient.When constructing, first reinforced concrete strip foundation being lifted into smooth road surface, then steel concrete trough slab is lifted in strip foundation, after having spliced, without any need for being connected between block with block and between block with basis, can use.
3) the required plant equipment of construction is few, and material usage is economized, and low its of energy consumption can be reused, and greatly reduces construction costs and other expenditure.Because dress prefabricated reinforced concrete strip foundation and prefabricated reinforced concrete trough slab are prefabricated in the factory, at the construction field (site), only need by grading, this bridge-type prefabricated reinforced concrete trough slab pavement system is laid in lifting, to temporary road, be finished rear recyclable, use in order to next time, save material usage further.
4) pavement construction is few to ambient influnence.Traditional pavement construction needs more construction machinery, produces larger noise when construction machinery runs.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, and does not almost affect job site environment.
5) namely spread i.e. use, open to traffic early.Once laying construction is complete, just can 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 namely 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, and the scene that is transported to when needed is laid.In structure, built-in fitting is housed, installs, removal suspension ring are very convenient, structure hoisting fashionable dress upper lift ring and 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 the various roadbeds with 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 be damaged in earthquake.
9) road slab surface arranges steel fibre surface layer, improves abrasion resistance and the crack resistance of road surface, thus improves the application life on road surface.
10) use of L-type rubber pad, can reduce vehicle to vibration that is basic and roadbed, improve the application life on road surface.
The present invention can be widely used in the quick reparation of temporary pavement construction or road.
