The technical scheme that the present invention provides is as follows: a kind of combination water-permeable brick, including water-permeable brick body, it is characterised in that: institute The right side of the water-permeable brick body stated and rear side are provided with fixed lobe, and the correspondence position of on the left of described water-permeable brick body and front side is provided with The groove matched with fixed lobe, described water-permeable brick body is provided with the osculum of up/down perforation.
Further preferred version, described osculum is located on described fixed lobe and is evenly distributed.
Further preferred version, described fixed lobe cross section is isosceles triangle, and described channel section is with described solid Fixed projection coupling.
Further preferred version, the front of described water-permeable brick body is provided with anti-slip tank laterally and/or longitudinally, described The reverse side of water brick body is provided with rhone laterally and/or longitudinally.
Further preferred version, the groove combination that polylith water-permeable brick body embeds adjacent a piece with fixed lobe is spliced into Road surface, described osculum is hidden in adjacent groove.
The invention also discloses a kind of manufacture method combining water-permeable brick, comprise the steps:
1) first, the swaging die with water-permeable brick body shape is made: described swaging die includes the right side of water-permeable brick body Side and rear side are provided with the fixed lobe of triangle, and the fixed lobe of described triangle is evenly distributed semicircle osculum, institute State on the left of water-permeable brick body and the correspondence position of front side is provided with the groove of the triangle matched with fixed lobe, described water-permeable brick The front of body is provided with anti-slip tank laterally and/or longitudinally, and the reverse side of described water-permeable brick body is provided with row laterally and/or longitudinally Tank;
2) in swaging die, inject concrete mortar, after vibration, stand 3-12 hour;
3) demoulding, maintenance, store, obtain the water-permeable brick with concaveconvex structure.
The invention also discloses a kind of construction method combining water-permeable brick, comprise the steps:
1) arrange roadbed: by need the ground laying water-permeable brick lay tiny stone and or sand 10-20cm, arrange flat Whole;
2) lay water-permeable brick: start to lay from the one end on road surface or side, will with protruding side be placed on before and The right side, carries reeded side to be positioned at rear side and left side, before then being embedded in the front side of another block water-permeable brick and the protruding of right side The groove that face is corresponding with the right side, so continuity are laid until completing whole road surface;
3) having the gap of one fixed width between the most adjacent water-permeable brick, connect into entirety by concaveconvex structure, osculum is hidden Hiding in a groove, when raining, rainwater flows to ground along gap and osculum, then permeates the ground.
The technique effect of the present invention and advantage: this municipal administration water-permeable brick of paving the way, when carrying out road pavement, utilize male and fomale(M&F) Inlay fastening, be allowed to form an entirety, do not have and loosen and situation that single water-permeable brick tilts, and without under hardening The roadbed in face, facilitates rainwater infiltration;On side, particularly there is the discharge outlet of up/down perforation, accelerate rainwater infiltration, reduce road surface Hydrops;The laterally and/or longitudinally anti-slip tank in brick body front can increase friction, improves safety;Brick body reverse side laterally and/ Or longitudinal drainage groove can increase the contact area of brick body and sub-surface, reinforce stable.In the case of Severe rainstorm, water-permeable brick The osculum of body upper surface can carry out assisted drainage, the blocking of prevention gap, accelerates the speed of whole road surface drainage, as early as possible Recover the unimpeded of road surface so that pedestrian can pass through normally.
