Detailed description of the invention
Fig. 1 is the structure chart of the conductive porous cement concrete pavement of the embodiment of the present invention;
Fig. 2 is that the conductive porous cement concrete pavement of the embodiment of the present invention accesses the schematic diagram of conducting wire.
Wherein, 1 upper layer porous cement concrete;2 lower layer's porous cement concretes;3 grout compartments;4 roadbases;5 roadbeds; 6 perfusion graticules;7 holes;8 conducting wires;9 electrode plates.
Specific embodiment
The invention will be further described combined with specific embodiments below.Following embodiment is only used for clearly illustrating Technical solution of the present invention, and not intended to limit the protection scope of the present invention.
It is a kind of conductive porous cement concrete pavement provided in an embodiment of the present invention as shown in Fig. 1 to 2.The conduction is more Hole cement concrete pavement include the roadbed 5 being successively laid with from bottom to top, roadbase 4, lower layer's porous cement concrete 2, on Layer porous cement concrete 1.Along corresponding to each lane center being pre-designed in lower layer's porous cement concrete 2 The left and right sides is respectively arranged with a column grout compartment 3, and the perfusion of grout compartment 3 described in each column is filled with epoxy resin and copper powder mixture, And grout compartment 3 described in each column is connected by conducting wire 8 with the electrode plate 9 for being embedded in roadside.
Wherein, the col width of grout compartment 3 described in each column is 0.5m.Two column grout compartments, 3 middle part and the lane on each lane The distance of centreline space is 1-1.5m.
When laying, first making roadbed 5 and roadbase 4, making are installed on 4 top of roadbase after the completion according to a conventional method Template, the lower layer's porous cement concrete 2 for the 12cm thickness that paves.
After the completion of lower layer's porous cement concrete 2 paves, perfusion mark is drawn in 2 upper surface of lower layer's porous cement concrete Line 6;, should be in the two perfusion graticules 6 of each side picture for each lane center being pre-designed when drawing perfusion graticule 6, and position 0.5m is spaced in two ipsilateral perfusion graticules 6;Region between two ipsilateral perfusion graticules 6 is grout compartment 3, Mei Geche 3 middle part of grout compartment on road and the distance controlling between the lane center are within the scope of 1-1.5m.
Epoxy resin and copper powder are stirred evenly using blender, the stable slurry of forming properties, and by its uniform stall with goods spread out on the ground for sale It is layered on 3 surface of grout compartment at left and right sides of each lane center, vibration grouting is carried out using plate compactor, until the epoxy resin It is fully entered with copper powder mixture in the connectivity gap inside lower layer's porous cement concrete 2.Wherein, the epoxy resin Using bi-component epoxide-resin, copper powder common conductive copper powder.
Along road surface in the length interval every 500-1000m an optional cross section, in this cross section lane Shang Ge The middle position of two sides grout compartment 3 drills, and conducting wire 8 is accessed in the hole 7 being drilled, by 8 other end of conducting wire and 9 phase of electrode plate Even, it is embedded in roadside, fills the aperture in the hole 7 as electrified regulation electrode, and with the epoxy resin and copper powder mixture Full envelope is real.Wherein, electrode plate 9 is stainless steel electrode plate.
It is finished to the whole packings in all holes in whole road surface 7, and after forming intensity, thick upper of the 12cm that can pave at an upper portion thereof Layer porous cement concrete 1.After the completion of the pavement structure conserves in required time, the conductive porous cement concrete pavement I.e. making is completed.
In the case where ice and snow weather, the electrode plate 9 for being embedded in roadside can be dug out, be connected with power supply unit, electric current is logical Cross the epoxy resin that is perfused inside the electrode plate 9 and the conducting wire 8 conduction to the conductive porous cement concrete pavement with In copper powder mixture, stablizes after the epoxy resin and copper powder mixture energization and generate heat, the heat generated is by under its periphery Connectivity gap inside layer porous cement concrete 2 and the upper layer porous cement concrete 1 in portion disposed thereon is conducted to road surface, is made The temperature on entire road surface rises.When pavement temperature rises to it is above freezing when, the ice and snow on road surface just starts to melt, thus ice-melt Snow melting keeps the unimpeded of road;And ponding caused by ice dissolution is then more by the upper layer porous cement concrete 1, lower layer A large amount of connectivity gaps discharge in hole cement concrete 2, to guarantee the drying property and road-ability on road surface.
Only in each lane, perfusion width is two column of 0.5m for the epoxy resin and copper powder mixture, and width is perfused Can artificially control, will not in road surface water barrier formed below, thus when will not influence rainy day and snow melting road surface drainage it is smooth It is logical.Two column, and two column asphalt mixtures modified by epoxy resin of each lane perfusion are perfused in the epoxy resin and copper powder mixture under each lane The position of rouge and copper powder mixture substantially immediately below the tire of driving vehicle, even if thus when ice and snow is thicker, still can will The ice and snow heating and melting of wheel lower part guarantees that road surface is unimpeded.
The present invention is disclosed with preferred embodiment above, so it is not intended to limiting the invention, all to take equivalent replacement Or the scheme technical solution obtained of equivalent transformation, it falls within the scope of protection of the present invention.
