The above raw material is added in batch mixer, will enter to account for the water of mixture quality 40-45% after stirring, with 250-300r/
The rotating speed of min continues to stir 20-25min, obtains required pervious bed slurry；
(3) permeable formable layer：Brick core is fixed in mold cavity, mold is closing and sealing off, is injected into mold permeable
Layer slurry opens mold and demoulds adobe, then use water penetration slurry by mold after the adobe preliminarily dried solidification in mold
Support portion is complete in the groove filling that brick body surface is formed, and is smoothly modified to adobe surface；
(4) brick bat drying：Adobe after finishing is sent in hothouse, processing is dried, dry indoor dry temperature
Degree is 120-150 DEG C, and the moisture content of the adobe pervious bed after drying process is 5-8%；
(5) water-permeable brick is fired：Adobe after drying is sent in high temperature kiln and is fired, the heating of sintering procedure
Journey is divided into three steps：Respectively it is warming up to 200 DEG C of preheating section, 200-500 DEG C of the first heating section, second liter of 500-700 DEG C
Temperature section；The high-temperature firing stage is entered after heating, firing temperature is 850-900 DEG C, and firing time 5-8h, firing terminates
After be sent to cooling section cooling, the speed that cools is 3-5 DEG C/min, and temperature is reduced to kiln discharge after room temperature；
(6) water-permeable brick conserves：The stacking on stockyard by the water-permeable brick after kiln discharge, to the water-permeable brick watering after stacking, watering
Frequency be 2-3d/ times, natural curing 15-20d obtains required water-permeable brick.
Preferably, the surface minimum-value aperture of brick core inner through-hole is 7-9mm, and the inside maximum diameter of hole of through-hole is 10-13mm.
Preferably, according to mass fraction, the raw material of permeable layer material includes：58-62 parts of flyash, 23-25 parts of clay, water chestnut

Preferably, alumina silicate fibre is chopped strand, a diameter of 2-3 μm of alumina silicate fibre, fibre length 3-4mm.
Preferably, the thickness of the pervious bed of brick wicking surface cladding is 1-1.5cm.
Preferably, brick bat drying is handled by the way of dried by hot air stream at high temperature in hothouse.
Preferably, in water-permeable brick sintering procedure, 1-2 DEG C of heating rate/min of preheating section；The heating speed of the first heating section
Spend 0.5-1.5 DEG C/min, 2-3 DEG C of heating rate/min of the second warming-up section.
Preferably, the stockyard in water-permeable brick maintenance processes is shading formula stockyard, and stockyard surrounding keeps good ventilation.
The present invention has following advantageous effect：
The pervious bed material preparation for the brick core and outer layer that the type water-permeable brick is manufactured by waste and old common brick forms, and brick core inner passes through
Reamer is expanded to bore by fusiform through-hole, after permeable layer material filling formation, permeable layer material is not only coated on brick core outer layer,
It is packed into the through-hole of brick core inner, these columnar seepy materials can become the penetrating passage in brick body；Therefore the type is multiple
The water permeability for closing water-permeable brick is very outstanding.
The water permeability that the through-hole of brick core inner is applied not only to water-permeable brick is promoted, and can also significantly improve the structure of water-permeable brick
Strength and stability；The intensity of brick core prepared by common brick brick body is very high, and seepy material can improve compound in the filling of brick in-core
The integrated degree of brick body；And since the through-hole at brick core back is in fusiform, after dank material casting, between two kinds of materials
It can keep combining very much force effect by force, the dank material for being coated on outer layer is difficult to be separated from each other with water-permeable brick, is not in
The problem of water material falls back；Therefore the stability of the type composite water permeable brick is more preferable, structural strength and compressive resistance also higher.
Wherein, in order to improve the tensile strength of seepy material, alumina silicate fibre is specially added in pervious bed slurry, it is this
The use of ceramic fibre can not only improve the tensile strength of brick body, additionally it is possible to promote the refractoriness of brick body.
In the preparation process of the type composite water permeable brick, a large amount of discarded common bricks of old building removal generation have been used；It is this
Although old-fashioned construction material intensity is high, because energy consumption and resource consumption are serious therefore rarely needed.Pass through the work
Skill can effectively clear up this discarded building waste, reduce pollution of the building waste to environment, have higher
The value of environmental protection；And because largely using building castoff as raw material, the production cost of the water-permeable brick is also reduced,
Economic value higher.
