In the last few years, along with improving constantly of people's environmental consciousness, the application of water permeability environment-friendly materials in road surfacing material was also more and more general, had formed the permeable building products such as the steady basic unit of water, cement concrete with water permeability and preformed bricks.Certainly, the processing mode of curb is also increasing gradually, all the curb stone structure has been made effective change in the patents such as " with the curb of weep hole ", " a kind of road drainage system ", to reach the purpose of draining.But these technology are that structure or the shape to goods made change in process, and its material product itself does not have new function.And pervious concrete is a kind of environment-friendly type concrete that rises in the builing industry in the last few years, have permeable, ventilative, alleviate " heat island effect ", improve the advantage such as water circulation, the research report that this problem is relevant also gets more and more.
The utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of supporting porous concrete road surface curb, is used for solving the problems of the prior art.
The utility model provides a kind of curb, comprise vertical block and horizontal block, the height of described vertical block is higher than horizontal block, the bottom of described vertical block be connected the side of block and connect, the inside of described vertical block and horizontal block is the cellular structure with a plurality of apertures.
Described cellular structure is the gelling that has utilized slag itself, makes aggregate produce point by cement and is connected with the electric welding formula of point type, thereby form cellular structure.
Preferably, described vertical block and horizontal block are cuboid, and the equal in length of vertical block and horizontal block.
Preferably, the length of described vertical block and horizontal block is 40-100cm.
Preferably, the side of the bottom of described vertical block be connected the side of block and connect, an end of described vertical block is provided with projection, the other end is provided with recess, shape and the size of described projection and recess match.
Preferably, described projection be shaped as cuboid, the parallel sided of described projection is in the side of described vertical block.
Curb provided by the utility model, the mat formation boundary stones of pavement edge of a kind of water permeability goods, can be used in the boundary line of distinguishing roadway, sidewalk, greenery patches, isolation strip and other parts of road on the road surface, play and ensure pedestrian, vehicular traffic safety and guarantee the neat effect of pavement edge, have certain water permeability because it has pore structure, can play the effects such as buffering surface gathered water.
The utility model realizes that the method for described cellular structure is: be primary raw material by slag, with other materials composite through mechanical pressing to obtain to have the constructional materials of loose structure, because the form porous of itself is so that this curb itself has pervious function.Its concrete preparation method comprises the steps:
1) raw material is weighed, mixing, pour mould into;
The mould that 2) material will be housed pushes in the vaccum-pumping equipment and vacuumizes;
3) material is carried out the strong vibration extrusion forming, wherein, the pressure of pressurization is 100-200KN, and be 60-120 second pressing time;
4) the steel slag concrete goods of moulding are taken out, and be put into fog room and carry out maintenance, curing time is generally 3-7 days;
5) the steel slag concrete goods that maintenance is good carry out the machine smoothing, and polishing obtains described high-strength high-permeability steel slag concrete product.
The slag raw material that adopts among the described preparation method is the slag like " steel sand beans " form of only producing for upper flow regime steel-smelting clinker, the quick shrend granulating technique of warp.Such slag is without stability problem, is a kind ofly to use especially for a long time than great, compact structure, good security, wear-resisting, high-quality inorganic non-metallic high-abrasive material that hardness is high, and as hard as flint has better Synthesis durability energy.Slag is higher than the hardness of stone in addition, adhesive property is better, permeable effect is also more excellent.Strength grade of the present utility model can reach more than the Cc40, and permeability rate keeps higher level simultaneously, more than 3mm/s.
