Specific embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein Described specific embodiment is merely to illustrate and explains this utility model, is not limited to this utility model.

As shown in Figures 1 to 8, this utility model provides a kind of road paving structure, for being laid on water-permeable brick 40, institute Stating road paving structure includes the plastic pallet 30 with multiple permeable holes 31 and is formed in saturating on the plastic pallet 30 The shape of water coagulation soil layer 20, pervious concrete layer 20 and plastic pallet 30 is adapted, plastic pallet 30 have it is multiple to Lower buckle 32 of the vertically extension in strip and multiple confession instruments stretch into the removal hole 33 for stirring buckle 32, and buckle 32 is arranged at plastics The lower surface of loading plate 30 and adjacent with removal hole 33, pervious concrete layer 20 has via 21 corresponding with removal hole 33, often The side of individual buckle 32 is convexly equipped with dop 321, and the side of water-permeable brick 40 is provided with and is available for dop 321 to block fixed fixture block 41.

In road paving structure of the present utility model, pervious concrete layer 20 is by will be containing the first aggregate and first What the mixture of binding agent solidify to form, and the first binding agent contains hydrophilic agglomerant.The porous of pervious concrete layer 20 and Permeable hole is little, not only with water permeability, additionally it is possible to play a role in filtering, and prevents granule larger on road from entering wherein. Plastic pallet 30 plays a part of to carry pervious concrete layer 20 as the skeleton of road paving structure.

Specifically, the method for formation road paving structure of the present utility model can be：Pervious concrete layer 20 will be formed Each material mixing it is uniform, obtain mixture, and add this mixture in the mould of pervious concrete layer 20, this into Plastic pallet 30 is pre-placed in pattern tool, has then been cured to form in cured condition tight with plastic pallet 30 The close pervious concrete layer 20 being combined together.

Road paving structure of the present utility model is navigated on water-permeable brick 40 by the cooperation of dop 321 and fixture block 41. When needing to install fixed, the road paving structure is attached on water-permeable brick 40, pushing makes dop 321 block fixture block 41 i.e. Can；When needing to pull down, strip instrument, such as screwdriver are used, stretch into from via 21 and removal hole 33 and stir buckle 32 so as to Generation slight deformation, dop 321 departs from fixture block 41, then removes the road paving structure.

Road paving structure dismounting of the present utility model and installation are all relatively simple quick, when carrying out scale installation, safeguarding, A large amount of manpowers will not be expended.

The shape and structure of dop 321 can have various, and such as cylindrical body upper end arranges the raised line of evagination and blocks for dop 321 Firmly, or inverted cone etc..In the illustrated embodiment, it is trigonocephaly in the upper end of fixture block 41, overall is in arrow-shaped, trigonocephalic Upper-end inner diameter reduces, and lower end evagination forms outer, and buckle 32 can block the outer and fix.The fixture block 41 of placed arrow type, not only can The effect of dop 321 is blocked in realization, and when needing to remove buckle 32, extracting tool front end is stretched into into removal hole 33, is against The inclined-plane of trigonocephaly upper end slides, and after sliding into extreme position, power is decomposed into horizontal force by triangular ramp, is all applied to card On button 32, the deformation of buckle 32 is forced to depart from fixture block 41, extracting tool is without the need for complex operations, it is only necessary to vertically push, and simplifies The operation of unloading process, further saves manpower consumption.

The upper surface of dop 321 is plane, it is ensured that clamping firmly, and under the compressing of instrument, is easily slipped, its The inclined-plane that lower surface is inserted for ease of the trigonocephaly of fixture block 41, during installation, directly presses, the lower surface of dop 321 and the upper end of fixture block 41 Sliding is close in face, forces buckle 32 to deform, and snaps in fixation.

In road paving structure of the present utility model, the combination of two of multiple buckles 32 is a buckle group, in each card In button group, the opposite flank of two buckles 32 is provided with dop 321, and the distance of the two opposite flank more than trigonocephaly outer Width.Two buckles 32 of buckle group are connected to the both sides of fixture block 41 simultaneously, are sandwiched centre, make to connect and fix more firm Gu.

In the illustrated embodiment, the road paving structure and water-permeable brick are rectangle, under road paving structure Along the corner of rectangle, uniform ring is arranged with four groups of buckle groups at end, and each buckle group is adjacent to a removal hole 33, i.e., two cards Button 32 shares a removal hole 33, so only departs from the buckle 32 on the one side in four groups of buckle groups, you can road surface is pulled in inclination Paving structure is removed, and under the premise of dismounting easily is ensured, can reduce the quantity of removal hole 33.

According to this utility model, in order to the side for ensureing road paving structure flushes with the side of water-permeable brick 40, it is preferable that The side of water-permeable brick 40 is provided with the groove 42 connected with the upper surface of water-permeable brick 40, and fixture block 41 is formed on groove 42.

In sum, road paving structure of the present utility model is arranged on water-permeable brick 40, and water-permeable brick 40 can be formed Protection, it is to avoid the direct impact of pedestrian or vehicle to water-permeable brick 40, when road paving structure occur because of life-time service abrasion or During damage, the road paving structure that can be easily removed and more be renewed, water-permeable brick 40 then due to withstand shocks it is less because This can be continuing with, and the service life of water-permeable brick 40 is significantly extended in this way.Also, because road paving structure is played The effect of impurity screening so that as long as water-permeable brick 40 can be permeable, this greatly reduces the requirement (example to permeable brick Such as, water-permeable brick 40 can be manufactured more than second aggregate and the second binding agent of the first aggregate using particle diameter, or using by In made by impermeable material, the brick with water stream channel be used as water-permeable brick 40), so as to greatly reduce the system of water-permeable brick Cause this.
