Abstract

The utility model provides a water permeability road structure which includes the metalling, the concrete layer that permeates water, the brick mortar levelling layer and the brick that permeates water permeate water, the metalling is laid on bottom dirt bed, permeate water concrete layer, the brick mortar levelling layer and permeate water the brick in proper order from lower supreme laying on the metalling of permeating water. The embodiment of the utility model provides a water permeability road structure compares with prior art, and its advantage lies in: through set up the metalling, the concrete layer that permeates water, permeate water brick mortar levelling layer and the composite construction of brick of permeating water, the metalling has guaranteed with the concrete layer that permeates water that the road has higher intensity, simultaneously through the brick mortar levelling layer and the brick that permeates water of permeating water, has guaranteed that the road has good water permeability.

Description

Water penetration road structure

Technical field

The utility model relates to road construction technical field, especially a kind of water penetration road structure.

Background technology

In the use material on highway in China road surface, relatively more conventional is to use the semi-rigid materials such as pitch, thisBe mainly the advantage due to the self character of pitch material, but it is at two seasons of winter in summer and day and night temperature,And the impulsive force of automobile tyre, easily there is crackle, this can affect the service life of highway, also increasesThe maintenance cost in later stage, is unfavorable for falling integrated cost, so just causes usability poor, has certain deficiency,Can better not be used for town road construction; And the bad hydraulic permeability of existing road.

Utility model content

In view of this, the utility model provides a kind of and can take into account the permeable of maintenance cost and highway service lifeProperty road structure.

A kind of water penetration road structure, it comprises metalling, pervious concrete layer, water-permeable brick mortar levelling layerAnd water-permeable brick;

Metalling is layed on bottom dirt bed;

Pervious concrete layer, water-permeable brick mortar levelling layer and water-permeable brick are layed in metalling successively from bottom to upOn.

In water penetration road structure described in the utility model, described pervious concrete layer is that half dry is saturatingWater coagulation soil layer.

In water penetration road structure described in the utility model, described half dry pervious concrete layer comprisesTwo layers of plastic mesh flake, and concrete between two layers of plastic mesh flake.

In water penetration road structure described in the utility model, described water-permeable brick mortar levelling layer is half stiffProperty water-permeable brick mortar levelling layer.

In water penetration road structure described in the utility model, the thickness of described metalling is greater than 200mm,Aperture is greater than 40%.

In water penetration road structure described in the utility model, described metalling can be rubble or cobble,The particle diameter of rubble or cobble is 20-40mm.

In water penetration road structure described in the utility model, described half dry pervious concrete layer thickDegree is 150-200mm.

In water penetration road structure described in the utility model, described half dry water-permeable brick mortar levelling layerThickness be 20mm.

In water penetration road structure described in the utility model, the thickness of described water-permeable brick is 60-80mm.

Compared with prior art, its advantage is the water penetration road structure that the utility model provides: by establishingPut the composite construction of metalling, pervious concrete layer, water-permeable brick mortar levelling layer and water-permeable brick, metallingEnsured that with pervious concrete layer road has higher intensity, simultaneously by water-permeable brick mortar levelling layer andWater-permeable brick, has ensured that road has good water penetration.

Detailed description of the invention

As shown in Figure 1, at a kind of water penetration road structure of the utility model embodiment, it comprises metalling20, pervious concrete layer 30, water-permeable brick 50 mortar levelling layers 40 and water-permeable brick 50.

Metalling 20 is layed on bottom dirt bed 10; Alternatively, the thickness of described metalling 20 is greater than200mm, aperture is greater than 40%. Metalling 20 itself has water penetration, and metalling 20 can divideLoose vehicle is for the grinding pressure of road.

Alternatively, described metalling 20 can be rubble or cobble, and the particle diameter of rubble or cobble is 20-40mm.

Pervious concrete layer 30, water-permeable brick 50 mortar levelling layers 40 and water-permeable brick 50 spread successively from bottom to upBe located on metalling 20.

Alternatively, described pervious concrete layer 30 is half dry pervious concrete layer 30. Half dry is permeableConcrete layer 30 itself has water penetration, is conducive to going deep into of surface water, improves the permeable, ventilative of earth's surfaceProperty, can regulate the temperature and humidity on earth's surface. The compression strength of half dry pervious concrete layer 30 is large simultaneously.

Alternatively, as shown in Figure 2, described half dry pervious concrete layer 30 comprises two layers of plastic mesh flake31, and concrete 32 between two layers of plastic mesh flake. Plastic grid sheet 31 can increase road greatlyTension pressure.

Alternatively, described water-permeable brick 50 mortar levelling layers 40 are half dry water-permeable brick 50 mortar levelling layers 40.Half dry water-permeable brick 50 mortar levelling layers 40 itself have water penetration, and can play and overcome roadStructural plane is uneven or the gradient is carried out the effect of levelling 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 layers 40 is 20mm.

Alternatively, the thickness of described water-permeable brick 50 is 60-80mm. Water-permeable brick 50 itself has water penetration,And there is good permeable, permeability, can make rainwater permeate the ground rapidly, simultaneously at water-permeable brick 50 quiltsWhen destruction, can be replaced easily.

Compared with prior art, its advantage is the water penetration road structure that the utility model embodiment provides:By metalling 20, pervious concrete layer 30, water-permeable brick 50 mortar levelling layers 40 and water-permeable brick 50 are setComposite construction, metalling 20 and pervious concrete layer 30 have ensured that road has higher intensity, simultaneouslyBy water-permeable brick 50 mortar levelling layers 40 and water-permeable brick 50, ensure that road has good water penetration.

Be understandable that, for the person of ordinary skill of the art, can be according to of the present utility modelTechnical conceive is made other various corresponding changes and distortion, and all these change and distortion all should belong to thisThe protection domain that utility model right requires.
