Abstract
The utility model discloses a permeable ground structure which comprises a surface layer, a cushion layer, a basic layer and a soil layer sequentially from top to bottom, and is provided with an expansion joint running through all the layers, wherein the expansion joint is filled with a permeable net; the wide band of the expansion joint is 15-20mm, for increasing the corrosion resistance and friction of the surface layer, a sealing layer can be sprayed on the surface layer; the thicknesses of all the layers are respectively as follows: the surface layer is permeable concrete with the thickness of 30mm-120mm; the cushion layer is permeable concrete with the thickness of 80-180mm; the basic layer is formed by rolling and compacting sandy gravel or gravel sand and has a thickness of 150mm-300mm; and the soil layer is formed by packed soil with the compaction coefficient being greater than 0.93. The technical scheme solves the problem that the traditional permeable road surface is easy to form water accumulation to affect the traffic and the ground appearance and the like in the low-lying position, and is a major technological advancement in the permeable ground design field.
Description
Technical field
The utility model belongs to brick structure field, ground, road surface, particularly relates to a kind of pervious surface structure that occasions such as large-scale square, sports center, urban road are used that is adapted at, and reduces the harm that excess surface water causes.
Background technology
Along with the continuous development of urban construction, when in the city, building public place such as large-scale station, square, sports center, road, all must consider the influence of rainfall to road.Common outdoor ground adopts the concrete brick laying structure, and these concrete surface structures do not have permeability to rainwater, need alleviate the influence of ponding to ground foundation at underground designing and arranging water system.But under some extreme weathers; because amount of precipitation is intensive; the spacing distance of land drainage well is far away; be easy to cause the draining of drainage pipe unfavorable; and on road, square, can accumulate some rubbish usually; dead leaf etc., be easy to cause the obstruction of catch pit to cause surface gathered water, influence people's normal life order.Therefore, the ground brick structure that novel seepy material is made has obtained using widely in actual engineering, but for this permeable pavement structure, because there is gradient difference in ground, the heavy rain that intensity is big can cause seepage velocity slow, and ground is owing to exist the different lowland of height, thereby forms ponding in the lowland zone, and it is attractive in appearance etc. to influence traffic, ground in the short time.
Summary of the invention
The purpose of this utility model is to form ponding at low-lying place easily and influence defectives such as traffic, ground be attractive in appearance in the short time in order to solve existing infiltration road surface, and a kind of novel permeable pavement structure of design.
Realize that the above-mentioned purpose the technical solution of the utility model is that a kind of pervious surface structure is surface layer from top to bottom successively, bed course, basic unit and soil layer, this earth construction is provided with the shrinkage joint of running through each layer, fill permeable net in the shrinkage joint, the width at shrinkage joint is 15mm～20mm.For increasing the corrosion-resistant and frictional property of surface layer, can on surface layer, spray sealant.
For reaching the different load-bearing requirement in ground, each layer thickness is respectively: surface layer is that thickness is the permeable concrete of 30mm～120mm; Cushion thickness is the permeable concrete of 80mm～210mm; Basic unit is the sandy gravel of 150mm～450mm or is joined gravel and roll the structure that forms by thickness; Soil layer is to be formed by rammed earth, and coefficient of consolidation is greater than 0.93, and each layer thickness can require to select according to load capacity.
For increasing the emission effect of road pavement ponding, the bottom, shrinkage joint can be connected it by reasonably distributing with drainage pipe.
The utility model is compared with traditional pervious surface structure to have: (1) whole ground has adopted seepy material to lay, thereby it is underground to guarantee to realize that everywhere rainwater successfully permeates; (2) ground every a segment distance setting run through shrinkage joint longitudinally, ground, can be with the ponding rapid permeability at low-lying place, cause undergroundly faster, reduce surface pond; (3) further reduced the alluvial of rainwater by being connected of shrinkage joint and subsoil drain, reduced the immersion damage of rainwater ground at low-lying place.Therefore, of the present utility model simple in structure, Costco Wholesale is cheap, has realized the timely translocation when the recycling and rainfall of rainwater is excessive.
Description of drawings
Fig. 1 is a pervious surface structural representation described in the utility model.
Among the figure, 1, sealant; 2, surface layer; 3, bed course; 4, basic unit; 5, soil layer; 6, the permeable net in the shrinkage joint.
The specific embodiment
Specifically describe of the present utility model below in conjunction with accompanying drawing, as Fig. 1 is pervious surface structural representation described in the utility model, this road structure comprises from top to bottom successively, surface layer 1, bed course 3, basic unit 4, soil layer 5, this earth construction is provided with the shrinkage joint of running through each layer simultaneously, fills permeable net 6 in the shrinkage joint; For increasing the corrosion-resistant and frictional property of surface layer, can on surface layer, spray sealant, its thickness is generally in the 1mm.As shown in Figure 1, each layer of earth construction vertically run through at the shrinkage joint, and its width is between 15mm～20mm.Because this earth construction needs certain support strength, therefore as follows for the thickness requirement of each layer, surface layer is that thickness is the permeable concrete of 30mm～120mm; Cushion thickness is the permeable concrete of 80mm～180mm; Basic unit is the sandy gravel of 150mm～300mm or is joined gravel and roll the structure that forms by thickness; Soil layer is to be formed by rammed earth, and coefficient of consolidation is greater than 0.93, each layer thickness such as following table under the concrete Different Weight:
In the practical application, for further improving the water permeability at shrinkage joint, can the shrinkage joint be connected with drainage pipe at underground, at the ponding at low lying ground place by the shrinkage joint and can permeate the ground, also can ponding be discharged smoothly simultaneously, reduce surface pond by drainage pipe.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art to some part wherein some changes that may make all embodied principle of the present utility model, belong within the protection domain of the present utility model.
