Description

A kind of porous pavement

Technical field

The present invention relates to bridge technical field of construction, and in particular to a kind of porous pavement.

Background technique

In present urban construction, urban flood control and drainage ability is very crucial, if road in time, cannot be incited somebody to action quickly Rainwater drains, and it will cause road ponding, influences normal pass, serious that ponding hidden danger will occur, cause personal injury and Property loss.

Also the structure that pervious floor tile can be used in existing urban road construction, divides into concrete structure, to a certain extent Really permeable effect can be played, situation lesser for precipitation is fully able to realize infiltration, if precipitation is biggish Situation, since secondary structure only relates to drain by lower infiltration mode, but the speed permeated is limited, and the concrete structure of bottom holds very much Easily reach infiltration to be saturated, but ponding between road.

In addition, during road pavement, it is contemplated that by the effect of water water conservancy diversion, often design high among road, two sides Reduced structure can only be the height change of internal structure layer, internal structure layer is to surface layer since the laying depth of surface layer is fixed The active force that do not tighten, in long-time use process, surface layer is easy to make to crack, and needs to remedy road, influences beauty.

Summary of the invention

In conjunction with the deficiencies in the prior art, the purpose of the present invention is to provide a kind of porous pavements, existing permeable to solve The problem of permeable effect difference in road surface and road surface are easy cracking.

To achieve the above object, the technical scheme is that

A kind of porous pavement, including roadbed, which is characterized in that be equipped with bed course above the roadbed, set above the bed course There is screed, the top of the screed is equipped with surface layer, and the screed includes bottom surface, convex ribs are equipped at intervals on the bottom surface, Reinforcing bar is equipped in the convex ribs, the section of the screed is matrix structure.

Further, the screed with a thickness of 90-150mm, the thickness of the bottom surface accounts for the thickness of the screed 2/3rds.

Further, binder couse is equipped between the screed and surface layer, the binder couse is filled out with screed cooperation It fills, the highest top surface of the binder couse is higher by the highest top surface 50mm of the screed.

Further, the binder couse is cracking resistance pervious concrete.

Further, the bed course is that rubble or building aggregate are laid with, with a thickness of 100-200mm.

Further, the surface layer is that pervious asphalt is mixed to prepare with concrete.

The present invention has the advantage that

The porous pavement of the utility model, through the screed structure in design matrix type section, on being laid on road Afterwards, bottom plate can play the role of stable effect, and convex rib structure, which plays, tenses main structure layer, to prevent surface layer disconnected It splits, stability is improved with binder couse male-female engagement, in addition, groove structure, rain is actually integrally formed in the screed mechanism of matrix It can play the role of water conservancy diversion after underwater infiltration, improve drainage efficiency.

Detailed description of the invention

Fig. 1 is the cross section structure schematic diagram of porous pavement provided by the embodiment of the utility model.

Fig. 2 is the schematic perspective view of screed in porous pavement provided by the embodiment of the utility model.

Wherein: 1, roadbed；2, bed course；3, screed；31, bottom surface；32, convex ribs；33, reinforcing bar；4, surface layer；5, binder couse.

Specific embodiment

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..

As described in Figure 1, Fig. 1 shows porous pavement provided by the embodiment of the utility model, including roadbed 1,1 top of roadbed Equipped with bed course 2, screed 3 is equipped with above bed course 2, the top of screed 3 is equipped with surface layer 4, and the section of screed 3 is matrix knot Structure, surface layer 4 are that pervious asphalt is mixed to prepare with concrete.

Wherein, bed course 2 is that rubble or building aggregate are laid with, and the partial size of fragment uses the material of 30-60mm, mainly from Sieved in building waste, bed course 2 its with a thickness of 100-200mm, after laying, pass through dilution cement encapsulating formed rock-steady structure layer.

Specifically, screed 3 is up-down structure, including bottom surface 31, convex ribs 32 are equipped at intervals on bottom surface 31, make screed 3 Upper structure form through slot structure, improve lateral load-bearing stress, be equipped with reinforcing bar 33 in the convex ribs 32, can further will be convex 32 structure of muscle tenses, and promotes load-bearing capacity to a greater extent.

Wherein, screed 3 with a thickness of 90-150mm, the thickness of bottom surface 31 accounts for 2/3rds of the thickness of screed 3, mentions Guarantee the stability of structure while high stress-bearing capability.

Embodiment still more preferably is equipped with binder couse 5, binder couse 5 and the sand between screed 3 and surface layer 4 The cooperation filling of pulp layer 3, the highest top surface of binder couse 5 is higher by the highest top surface 50mm of screed 3.

Binder couse 5 is cracking resistance pervious concrete, surface layer 4 and screed 3 preferably can be bonded as an entirety knot Structure improves the stability of road.

Wherein, optionally, pervious asphalt fragment can also be added in the upper layer through slot structure of screed 3, improving sand While the tight type and raising road surface water permeable ability of cooperation between pulp layer 3 and binder couse 5, the mesh that can be flow backwards is played 's.

When the construction of seepage pavement of the utility model, firstly, roadbed 1 is modified smooth, compacting, pretend in 1 two sides of roadbed Riser, is put into rubble or building aggregate, and air hose dilutes cement, it is structure-characterized it is firm after, make the bottom surface 31 of screed 3, It installs riser on ground additional, reinforcing bar 33 is added, make convex ribs 32, after 3 stabilized structure of screed, be laid with binder couse 5, be finally laid with Surface layer 4, compacting, it should be noted that the cross-wise direction of screed 3 is towards the roadside of road, it is ensured that the upper structure of screed 3 Through slot water guide is to roadside, and the permeable water transmitting ability of the stable structure of the utility model is strong, while stabilized structure, and road surface is not easy to crack.

Although above having used general explanation and specific embodiment, the present invention is described in detail, at this On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore, These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
