Description

A kind of high-mechanic block-stone pavement structure being applicable to heavy traffic
Technical field
This utility model belongs to road engineering technical field, relates to a kind of pavement structure, particularly relates to one and is applicable to weight The high-mechanic block-stone pavement structure of traffic.
Background technology
In today that environmental conservation theory is rooted in the hearts of the people day by day, controlling of natural disaster urban rainwater caused along with country Reason and the pay attention to day by day of water resource recycling, " sponge city " builds the expansion like a raging fire in the whole nation, to former in protection While having the natural disaster that the destroyed Ecology of ecosystem, recovery, improvement urban rainwater bring, reach rain to greatest extent Water collection, water-retention, infiltration, water purification and water resource release etc. circulate benignly, and protect urban water ecosystem.
Porous pavement is the important component part of sponge urban construction.The most conventional permeable pavement structure has three kinds: thoroughly Water coagulation soil surface, asphalt paving, block-stone pavement.Wherein, block-stone pavement is mainly used in footpath or some light traffics Road, which greatly limits the range of application of block-stone pavement, adds economic input.
Utility model content
The purpose of this utility model is to provide a kind of high-mechanic block-stone pavement structure being applicable to heavy traffic, this pavement structure Can adapt to heavy traffic load feature, meet accumulated standard axle time Ne=1.2 × 107~2.5 × 107The road in (secondary/track), On the premise of ensureing the traffic capacity, can effectively reduce the cost of porous pavement.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of high-mechanic block-stone pavement structure being applicable to heavy traffic, it is characterised in that be applicable to the height of heavy traffic described in: Granular cushion that carrier block stone pavement structure includes being laid on the most successively on soil matrix, gravel-sorted subbase, level Join basic unit on rubble, pervious concrete cutting optimal, filter course, medium sand cushion and block stone upper layer.
As preferably, the block stone upper layer that this utility model is used is to be paved by cement concrete prefabricated section stone to form; It is filled with calking between adjacent cement concrete prefabricated section stone;Described calking is sand;Described cement concrete prefabricated section stone Length, width and height size be 400mm, 250mm and 200mm respectively.
As preferably, the thickness of the medium sand cushion that this utility model is used is 30mm.
As preferably, the filter course that this utility model is used is that chinlon filters layer of cloth.
As preferably, the pervious concrete cutting optimal that this utility model is used is Sand-free permeable concrete cutting optimal, institute The thickness stating pervious concrete cutting optimal is 80mm, and voidage is 15~25%.
As preferably, on the graded broken stone that this utility model is used, the crush values of the building stones in basic unit is not more than 25%, On described graded broken stone, the compactness of basic unit is not less than 100%, and CBR value is not less than 100%, the thickness of basic unit on described graded broken stone Degree is 200mm.
As preferably, the crush values of the building stones in the gravel-sorted subbase that this utility model is used is not more than 25%, The compactness of described gravel-sorted subbase is not less than 100%, and CBR value is not less than 100%, the thickness of described gravel-sorted subbase Degree is 200mm.
As preferably, the crush values of the building stones in the granular cushion that this utility model is used is not more than 26%, institute The compactness stating granular cushion is not less than 98%, and CBR value is not less than 100%, and the thickness of described granular cushion is 200mm。
As preferably, the compression rebound modulu of the soil matrix that this utility model is used is not less than 60MPa.
This utility model compared with the prior art, has the following advantages and beneficial effect:
This utility model provides a kind of high-mechanic block-stone pavement structure being applicable to heavy traffic, including the most successively Basic unit, pervious concrete cutting optimal, mistake on the granular cushion that is laid on soil matrix, gravel-sorted subbase, graded broken stone Filtering layer, medium sand cushion and block stone upper layer.The pavement structure that this utility model is used is permeable block-stone pavement structure, it By the requirement tightened up to soil matrix compression rebound modulu, use the graded broken stone of big thickness and tightened up compactness and CBR controls, and provides more preferable plate body bearing capacity by pervious concrete so that block-stone pavement is ensureing that pavement structure is saturating On the basis of water, it is provided with enough bearing capacitys and undertakes the effect of heavy traffic load.
Accompanying drawing explanation
Fig. 1 is the structural representation of pavement structure provided by the utility model;
Wherein:
1-soil matrix;2-granular cushion;3-gravel-sorted subbase;Basic unit on 4-graded broken stone;5-pervious concrete Cutting optimal;6-filter course;7-medium sand cushion;8-block stone upper layer.
