Detailed description of the invention
As shown in Figure 1, at a kind of road structure with permeable barricade of the embodiment of the present invention, it comprises macadam 20, pervious concrete layer 30, water-permeable brick 50 mortar levelling layer 40, water-permeable brick 50, permeable barricade 60 and cage 70.
Macadam 20 is layed on the dirt bed 10 of bottom original soil rammed; Alternatively, the thickness of described macadam 20 is greater than 200mm, and porosity is greater than 40%.Namely macadam 20 itself has water permeability, and macadam 20 can scattering vehicles for the grinding pressure of road.
Alternatively, described macadam 20 can be rubble or cobble, and the particle diameter of rubble or cobble is 20-40mm, or 10 ~ 30mm, and large small particle diameter is good than trying one's best with about 2 in a word.
Pervious concrete layer 30, water-permeable brick 50 mortar levelling layer 40 and water-permeable brick 50 are layed on macadam 20 successively from bottom to up; Permeable barricade 60 is arranged on road both sides.Cage 70 is arranged on permeable barricade 60 one or both sides, and extends along road.
Alternatively, described pervious concrete layer 30 is half dry pervious concrete layer 30.Namely half dry pervious concrete layer 30 itself has water permeability, is conducive to going deep into of surface water, improves permeable, the gas permeability on earth's surface, can regulate the temperature and humidity on earth's surface.The compressive strength of half dry pervious concrete layer 30 is large simultaneously.
As shown in Figure 2, alternatively, described half dry pervious concrete layer 30 comprises two layers of plastic mesh flake 31, and the concrete 32 between two layers of plastic mesh flake.
Alternatively, described water-permeable brick 50 mortar levelling layer 40 is half dry water-permeable brick 50 mortar levelling layer 40.Namely half dry water-permeable brick 50 mortar levelling layer 40 itself has water permeability, and can play and overcome road structure face and be uneven or the gradient and carry out levelling effect because existing.
Alternatively, the thickness of described half dry pervious concrete layer 30 is 150-200mm.
Alternatively, the thickness of described half dry water-permeable brick 50 mortar levelling layer 40 is 20mm.
Alternatively, the thickness of described water-permeable brick 50 is 60-80mm.Namely water-permeable brick 50 itself has water permeability, and has good permeable, permeability, and rainwater can be made to permeate the ground rapidly, simultaneously when water-permeable brick 50 is destroyed, can be replaced easily.
Alternatively, as shown in Figure 3, permeable barricade 60 is built into by the permeable wall brick 61 of multilayer, and same layer leaves gap 62 between adjacent permeable wall brick 61.
Alternatively, the material of permeable wall brick 61 can be permeable road kerb, and porosity is greater than 12%.Alternatively, permeable road kerb material is made up of cement 1 part, stone (3 ~ 5 parts) and Admixture.Alternatively, Admixture comprises naphthalene series high-efficiency water-reducing agent, high performance water reducing agent of polyocarboxy acid and aliphatic high-efficiency water reducing agent.Alternatively, the usage ratio of Admixture is the 0.4%-0.5% of cement, and above ratio is weight ratio.
As shown in Figure 4, the sectional view of Fig. 4 position cage 70; Cage 70 is offered through hole 71, ponding can be entered in cage by permeable wall brick 61.Cage 70 being provided with fixed block 72, being absorbed in soil for preventing cage.
Alternatively, the elevation of water of cage 70 is less than the upper level of macadam 20.Cage 70 can lay soil, make ground ponding also enter in cage 70 by the through hole 71 in cage 70, improve the storage capacity of road.
What the embodiment of the present invention provided has the road structure of permeable barricade compared with prior art, its advantage is: by arranging the composite construction of macadam 20, pervious concrete layer 30, water-permeable brick 50 mortar levelling layer 40 and water-permeable brick 50, macadam 20 and pervious concrete layer 30 ensure that road has higher intensity, simultaneously by water-permeable brick 50 mortar levelling layer 40 and water-permeable brick 50, ensure that road has good water permeability.And permeable barricade 60 is built into by the permeable wall brick 61 of multilayer, same layer leaves gap 62 between adjacent permeable wall brick 61, have employed the structure of " horizontal sealing is perpendicular does not seal ", ensure that road is connected with between outside.
Be understandable that, for the person of ordinary skill of the art, other various corresponding change and distortion can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
