Abstract
The utility model relates to a novel layered steel fiber reinforced concrete pavement structure applicable to highway pavements, bridge pavements, airport pavements and urban pavements, which includes a base layer, a water seal layer and a surface layer, wherein the base layer is cement-added stable gravel or graded gravel layer, the water seal layer is a slurry seal layer or an asphalt seal layer, and the surface layer is a layered steel fiber reinforced concrete layer. The utility model has the advantages that by adopting the gravelling technology for the old pavement, the resource is saved, and the strength of the lower base layer is improved; by adopting the slurry seal layer or the asphalt seal layer for the base layer, water seepage can be effectively prevented; by adding the corner steel for the layered steel fiber reinforced concrete pavement, the corner breaking problem caused by the fact that the layered steel fiber reinforced concrete pavement plates are overlong is solved, and the service lives of the pavement plates are prolonged; and by optimizing the existing pavement structure, the novel layered steel fiber reinforced concrete pavement structure has the characteristics of practicability, economy, feasibility and the like.
Description
Technical field
The utility model relates to a kind of various highway pavements that are applicable to, bridge floor, airfield pavement, urban pavement, the novel Layer-steel Fiber Reinforced Concrete Pavement structure on bus station road surface.
Background technology
Along with the birth of portland cement in 1824, concrete has appearred before and after 1830, and a kind of New Building Materials as at that time just are widely used in building and hydraulic engineering.The rigid pavement long service life, environmental protection, economy.Therefore; Many for a long time experts and scholar explore constantly that to improve concrete performance (mainly be to improve tensile property; The enhancing durability) the whole bag of tricks and approach are so having proposed a kind of is the advanced composite material (ACM) of matrix---fibrous concrete with the traditional plain concrete.The Layer-steel Fiber Reinforced Concrete Pavement face, the road face that a certain amount of steel fibre making of (about 1-4cm) spreading becomes in the certain thickness at (about 3-5cm) and top in the certain thickness of Common Concrete Pavement plate bottom.
Summary of the invention
The utility model technical problem to be solved is to above-mentioned prior art a kind of novel Layer-steel Fiber Reinforced Concrete Pavement structure to be provided; Concrete supporting capacity and durability have significantly been improved; But the thickness of attenuate concrete road surface, and structure has that the steel fibre consumption is few, construction costs is low, construction technology simple and feasible, workmanship advantages of higher.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: novel Layer-steel Fiber Reinforced Concrete Pavement structure; Include basic unit, water shutoff layer and surface layer; Said basic unit is covered with cement stabilized macadam or graded broken stone layer for adding; The water shutoff layer is slurry seal or tar seal, and surface layer is the layered steel fiber reinforced concrete layer.
Press such scheme, the cement factor that described basic unit adopts is 5%.
Press such scheme, described slurry seal thickness is 8mm-12mm.
Press such scheme, described tar seal thickness is 3cm-6cm.
Press such scheme, the place, centre joint plate angle of described layered steel fiber reinforced concrete layer is equipped with corner bar.
Press such scheme, the place, centre joint plate angle of described layered steel fiber reinforced concrete layer is equipped with corner bar.
Press such scheme, described corner bar adopts the welding of 10mm-12mm indented bars.
The utility model has the advantages that: adopt the rubblization technology to economize on resources to old pavement, improve the intensity of going to a grassroots level; Adopt slurry seal or tar seal effectively to prevent infiltration to basic unit; It is to solve the angle of rupture problem that the Layer-steel Fiber Reinforced Concrete Pavement plate produces because of plate is long, the application life of further improving road slab that Layer-steel Fiber Reinforced Concrete Pavement is added corner bar; Existing road structure is optimized combination, has practicality, economy, characteristics such as feasibility.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the structural representation of layered steel fiber reinforced concrete layer.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation, but this explanation can not constitute the restriction to the utility model.
Embodiment 1
Novel Layer-steel Fiber Reinforced Concrete Pavement structure includes basic unit 3, water shutoff layer 2 and surface layer 1, and said basic unit is covered with cement stabilized macadam or graded broken stone layer for adding; The cement factor that basic unit adopts is 5%; The water shutoff layer is a slurry seal, and slurry seal thickness is 8mm-12mm, and surface layer is the layered steel fiber reinforced concrete layer; Place, centre joint plate angle is equipped with corner bar 4, and corner bar adopts the welding of 10mm-12mm indented bars.
For the old pavement transformation, the concrete operations step is:
Old concrete road galletization (rubblization the mechanical execution) → steady basic unit of the water that paves (manual work or mechanical execution) → slurry seal or tar seal (manual work or mechanical execution) → overlay layered steel fiber reinforced concrete surface layer (contain and lay corner bar) → health → clearance.
Embodiment 2
Novel Layer-steel Fiber Reinforced Concrete Pavement structure includes basic unit 3, water shutoff layer 2 and surface layer 1, and said basic unit is covered with cement stabilized macadam or graded broken stone layer for adding; The cement factor that basic unit adopts is 5%; The water shutoff layer is a tar seal, and tar seal thickness is 3cm-6cm, and surface layer is the layered steel fiber reinforced concrete layer; Place, centre joint plate angle is equipped with corner bar 4, and corner bar adopts the welding of 10mm-12mm indented bars.
For newly-built road surface, the concrete operations step is:
Go to a grassroots level and handle → pave the steady basic unit of water (manual work or mechanical execution) → slurry seal or tar seal (manual work or mechanical execution) → overlay layered steel fiber reinforced concrete surface layer (contain and lay corner bar) → health → clearance.
