In addition to selecting suitable raw material, can also by mix-design and preparation technology and additive come reach proof strength and
The purpose of porosity.Top layer 14 is made up of vermilion pervious concrete, and top layer 14 is equally made of pervious concrete, permeable
Vermilion pigment is added in concrete so that top layer 14 is shown as vermilion, and convenient use person sees road clearly at night.Basic unit 11 is thick
Spend for 80mm, the thickness of pervious bed 12 is 200mm, and the thickness of drainage layer 13 is 80mm, and the thickness of top layer 14 is 40mm, each layer of reasonable distribution
Thickness, both ensured that porous pavement had stronger mechanical strength, while also possessed preferable water penetration.
As depicted in figs. 1 and 2, the both sides on top layer 14 are respectively arranged with square road tooth 15, road tooth along its length direction
15 inner side is provided with several equally distributed Drainage Divisions 2 along its length direction, and Drainage Division 2 includes vertically penetrating road
The groove 21 of the inner side of tooth 15, the sealing block 22 of the fitting madial wall of groove 21, square sealing block are provided with square groove 21
Square support block 23 is extended downward among 22 bottoms, the bottom of groove 21 is provided with positioned at the lower section of support block 23 and is used for
Guide the honeycomb duct 25 of rainwater.
As shown in Fig. 2 the both sides of support block 23 are provided with the cushion 24 for supporting sealing block 22, cushion 24 uses
A kind of hydro-expansive rubber disclosed in the patent of Application No. " 201010107698.9 ", its preparation technology is easy, has and meets
Hydroexpansivity, expansion rate is higher, and waterproof water-stagnating effect is good, and hydro-expansive rubber belongs to prior art, will not be described here.
As shown in Figures 2 and 3, insertion is provided with through hole 31 in cushion 24, and top and sealing block are provided with through hole 31
The back-moving spring 32 that end is fixed with the bottom of groove 21 simultaneously is fixed in 22 bottoms, and back-moving spring 32 is in contraction state.Sealing block
22 bottoms are provided with the first guide housing 33 being set in outside back-moving spring 32, and the bottom of groove 21, which is provided with fitting and is set in first, leads
The second guide housing 34 to outside frame 33, the lateral wall of the second guide housing 34 fitting madial wall of through hole 31.By the first guide housing 33 with
The cooperation of second guide housing 34 plays guide effect to back-moving spring 32, pressed home spring when avoiding the cushion 24 from expanding
32。
As shown in figure 4, the side wall of road tooth 15 is provided with the limiting plate 26 for sealing groove 21, penetrated among limiting plate 26
Be provided with the width identical opening 27 of support block 23, gap between the bottom of limiting plate 26 and top layer 14 be present, gap is less than
2mm.It can be expanded after cushion 24 absorbs water to surrounding, be easily separated from groove 21, block cushion 24 by limiting plate 26, make
Cushion 24 can only expand along its length.Top layer 14 is arranged to the middle slope shape reduced respectively to both sides in the width direction.
Rainwater on road surface can flow away along the upper table of top layer 14 of slope shape towards the road tooth 15 of both sides, avoid accumulation of rainwater on top layer 14
Upper surface.
The course of work：Rainwater falls through top layer 14, drainage layer 13, pervious bed 12 and basic unit 11 after porous pavement, and
The upper surface of top layer 14 is not accumulated in, the cushion 24 on road tooth 15 will be bedewed when water is excessive, due to hydro-expansive rubber
Characteristic with water-swellable, cushion 24 will become big, so as to prop up the sealing block 22 of top, the now bottom of support block 23
Honeycomb duct 25 will expose, and the rainwater accumulated on road surface will leave along honeycomb duct 25.
Because the top of back-moving spring 32 is fixedly connected with the bottom of sealing block 22, sealing block 22 can be drawn with back-moving spring 32
Stretch, while the first guide housing 33 can also be bonded the second guide housing 34 and slide, and make 32 flexible potential energy of back-moving spring.
When simultaneously there is no ponding, the water in cushion 24 is gradually lost in, and will narrow down to original size, reset on road surface
Spring 32 can also recover contraction state, further help support block 23 to reset, now support block 23 will cover honeycomb duct 25, keep away
Exempt from dust debris etc. and block honeycomb duct 25.
