Abstract
The invention provides the cement concrete pavement panel that a kind of surface layer bottom is provided with the grid-like rib of projection, and on roadbase, construct grid-like rib chase groove with the grid-like rib mould, and then the job practices of making cement concrete pavement.Adopt the present invention guaranteeing to save 1/3～1/4 cement concrete consumption on the pavement design intensity based.
Description
The present invention relates to a kind of cement concrete pavement panel, and when constructing this panel, the method for the latticed floor groove of structure on roadbase.The invention belongs to the highway engineering technical field.
Along with rapidly sending out of modern road traffic spent, the automobile of running at high speed is more and more higher to travel.Cement concrete pavement because have the intensity height, planeness is good, series of advantages such as long service life have obtained increasingly extensive employing.The method of in the past constructing the cement concrete pavement panel is, on the roadbase of compaction moulding, and the cement concrete of one deck equal thickness that paves.Construct this cement concrete pavement panel, the cement concrete consumption is big, causes and causes investment many, the cost height.Therefore how guaranteeing to reduce the consumption of cement concrete under the prerequisite that design strength requires, is one of problem of extremely paying close attention to of construction of the highway department.
Purpose of the present invention is to provide a kind of design strength that both can guarantee the road surface panel, can save the cement concrete pavement face road plate of cement concrete consumption again, and the method for constructing this road surface panel.
The feature of cement concrete pavement panel provided by the present invention is that in the bottom of cement concrete pavement panel, being provided with the road surface panel is the grid-like rib of the projection of one.The junction of grid-like rib and road surface panel is a circular arc.The height of grid-like rib projection can be according to the requirement of strength design of road surface panel.It highly is generally 0.5～4 times of top course thickness.The rib grid of this road surface panel can be square, rectangle, shape such as triangle or rhombus.
The job practices of this cement concrete pavement panel is: at first construct latticed chase groove on the roadbase of desiring the making cement concrete pavement.Its method has following two kinds:
1, earlier base materials such as lime, cement, clay, grit is paved on roadbase, before carrying out compacting operation, latticed mould to making with materials such as duroplasts or rubber, be placed on the smooth base material that paves, use the compacting machinary compacting then, in with the base material compacting, grid-like rib mould also embedding is pressed in the base material.After compacting operation finishes, the grid-like rib mould is taken out from base material, promptly on roadbase, be configured to grid-like rib chase groove.
2, on the tamping drum of road roller, install the grid-like rib mould, when road roller rolls base material, both on roadbase, rolled out trellis rib chase groove.
Job practices routinely then, making cement concrete on the roadbase that is configured with grid-like rib chase groove has promptly formed rib type cement concrete pavement panel.
Fig. 1～2nd, one embodiment of the present of invention.Fig. 1 is the drawing in side sectional elevation at rib type cement concrete pavement A-A place.1 side slope, 2 basic units, 3 cross rib bars, 4 surface layers, 5 vertical ribs among the figure.
Fig. 2 is a grid-like rib chase groove schematic diagram in the rib type cement concrete pavement basic unit.Among the figure: 6 grid-like rib grooves.
Rib in the present embodiment on the cement concrete pavement panel is the grid arrangements.
The cement concrete pavement panel that adopts the technical program to construct, the rib both sides and the bottom of its surface layer bottom and projection all closely are connected with roadbase, so the stressed and distortion of road surface panel evenly.Compare on the panel designs intensity based of assurance road surface with the cement concrete pavement panel of constructing equal thickness, can save cement concrete consumption 1/3～1/4, thereby reduce the cost of road surface panel.
Claims (4)
1, a kind of cement concrete pavement panel is characterized in that in the bottom of cement concrete pavement panel, and being provided with the road surface panel is the grid-like rib of the projection of one, and the junction of grid-like rib and panel is a circular arc.
2, the construction method of cement concrete pavement panel as claimed in claim 1, it is characterized in that, on roadbase, construct earlier grid-like rib chase groove, and then by general conventional job practices, making cement concrete on the roadbase that grid-like rib chase groove is arranged.
3, the building method of cement concrete pavement panel as claimed in claim 2, it is characterized in that described method of constructing grid-like rib chase groove on roadbase is, the grid-like rib mould that makes will be given, be placed on the smooth road basement material that paves, with compacting machinary with the base material compacting in, the embedding of grid-like rib mould is pressed in the base material, after compacting operation finishes, the grid-like rib mould is taken out from base material, promptly on roadbase, construct grid-like rib chase groove, and then by general conventional job practices making cement concrete on the roadbase that grid-like rib chase groove is arranged.
4, the job practices of cement concrete pavement panel as claimed in claim 2, it is characterized in that described method of on roadbase, constructing grid-like rib chase groove, on the cylinder of road roller, install the grid-like rib mould, when base material is carried out compacting operation, promptly on roadbase, construct grid-like rib chase groove, and then by general conventional job practices, making cement concrete on the roadbase that grid-like rib chase groove is arranged.
