Description
Technical field
Sponge urban construction is prepared with permeable using aluminosilicate industrial residue and boehmite the present invention relates to one kind
The method of brick, belongs to building material technical field.
Background technology
The earth's surface of modern city is progressively covered by material water-proof materials such as building and concrete, so as to form ecology
" artificial desert " on.Fluid-tight concrete and pitch etc. are as the main ground surface material in city so that decline naturally
Rainwater can not be natural and tripping permeate the ground；Thus be cause lack to urban surface temperature, humidity regulation ability it is main
Reason, " tropical island effect " for causing to produce so-called city or causes to see the waterlogging problem in sea in rainy season city.In order to alleviate to environment
Infringement, and the stable ecological environment in city can have fundamentally been administered, so as to propose the new general of construction " sponge city "
Read." sponge city ", is that metaphor city possesses the same function of sponge, is adapting to seasonal climate environmental change and reply nature
There is good " elasticity " in terms of disaster.Water suction, retaining, infiltration, water purification when raining, need " to release the water stored when arid
Put " and it is used, so as to allow migratory movement of the water in city more " nature ".
Natural way is combined by sponge urban construction with artificial measures, is ensuring the premise of municipal drainage prevention waterlogging safety
Under, realize that rainwater accumulates in urban area, permeates and purified to greatest extent, improve Rainwater Resources level, protecting ecology ring
Border.Build sponge city and seek to that there is " cavernous body "；" cavernous body " both includes the water system such as river, lake, pond, also including greenery patches,
City auxiliary facility as garden, permeable pavior brick.Rainwater by being oozed under these " cavernous bodies ", it is stagnant store, purification, reuse,
Last remainder runoff, so as to effectively improve the standard of sewerage system, is extenuated in city by being arranged outside pipe network, pumping plant
The pressure of flood.Sponge urban construction is a systemic engineering, but each critical component of systemic requirement of engineering is next organic
Combine, water-permeable brick is exactly one of sponge urban construction crucial organism.
Water-permeable brick is also seepage brick, Dutch brick etc., belongs to Green environmental-protection building material product.Raw material are generally to use water
Based on the concrete materials such as mud, sand, stone, vibrate pressurization product forming process to carry out mass production by mechanization orientation
Floor tile；Full sized brick forms for disposable compression, forms the not stratified homogeneity brick of global density uniformity.Water-permeable brick is for exploitation
Rainfall produced by the difference in functionality regions such as road, garden, square in construction area, takes appropriate measures, or at collection
Reason is recycled, or the recharging groundwater that permeates the ground, and rainwater resource, the raising self-purification ability of enviroment, improvement garden are made full use of to reach
Area's ecological environment, the purpose for adjusting Partial little climate.Water-permeable brick can be widely used in laying pavement or lightweight traffic garage
The road surface in road etc. and ground surface works, it may also be used for cell, garden, parking lot, shop, block, square, waterside bank protection, in park
The paving such as road and level land, airport and harbour.
At present, two major classes can be divided into from material and production technology in the water-permeable brick seen on the market.One class is with solid
Industrial waste, house refuse and building waste be primary raw material, by crush, shaping, high-temperature firing have water-permeable brick
Performance, meets the building and ornament materials of water-permeable brick standard, and it is called ceramic water-permeable brick by we；Another kind of is with inorganic non-metallic
Material is primary raw material, using organic or inorganic binding agent by shaping, solidifying with water-permeable brick performance, meet permeable
The building and ornament materials of brick standard.Because it need not burn till, so we are called non-ceramic water-permeable brick.Dai Wubin, Zeng Lingke,
Wang Hui et al. is at it《The present Research and development prospect of water-permeable brick》The method that several water-permeable bricks are described in one text：（1）Utilize
Shraff, cullet and clay develop environment-friendly ceramic water-permeable brick as primary raw material；（2）It is main former using gold tailings
Material, makees pore former with gangue, prepares Porous permeable bricks；（3）Be primary raw material using flyash, broken useless floor tile be bone
Material, clay make binding agent, prepare flyash water-permeable brick.As can be seen here, gangue, fine coal are used water-permeable brick in the market more
The solid industrial waste material such as ash, shraff, cullet, useless floor tile, gold tailings makees raw material, also seldom sees and uses aluminosilicate
Industrial residue and boehmite are water-permeable brick prepared by primary raw material.
The content of the invention
Sponge urban construction is prepared with thoroughly using aluminosilicate industrial residue and boehmite the invention discloses one kind
The method of water brick.Water-permeable brick produced by the present invention has a high mechanical strength, and water penetration is strong, the features such as good endurance, service life
It is long, have a wide range of application.
