Embodiment approach

[0026] Such as figure 1 with figure 2 As shown, when there is less ponding water in the road, most of the ponding water can flow directly into the water flow tank, or penetrate into the floor surface and / or facade surface layer first, and then flow into the water flow groove. Drainage of stagnant water; when there is a lot of stagnant water in the road, the stagnant water cannot be discharged in time only through the water flow tank, and the road stagnant water may overflow the water flow groove; therefore, preferably, the bottom position of the permeable part is not higher than the top surface of the base plate. When the accumulated water in the water flow groove overflows the water flow groove, it can also be smoothly discharged from the water permeable part. According to the present invention, as long as the pore diameters of the porous structure of the permeable part are ensured to be larger than the pore diameters of the porous structure of the bottom layer of the vert...

Embodiment 1

[0043] This embodiment is used to illustrate the curbstone provided by the present invention and its preparation.

[0044] 1000g perlite (average particle diameter is 3.5 millimeters), 100g cement and 100g water are mixed uniformly, obtain the mixture that forms base plate bottom layer and vertical plate bottom layer; In the steel curb bottom layer mold with holes, solidify at 40°C for 500min to obtain the bottom layer of the bottom plate and the bottom layer of the vertical plate with an integrated structure. The thickness of the bottom layer of the bottom plate and the bottom layer of the vertical plate is 10cm, and the diameter of the hole is 0.5mm. The porosity was both 15%.

[0045] Mix 1000g of silica sand (average particle diameter of 0.05mm), 100g of water-based epoxy resin (Bluestar New Material Wuxi resin, E-44) and 5g of diethylenetriamine to obtain a mixture that forms the surface layer of the bottom plate and the surface layer of the vertical plate ; Lay the mixt...

Embodiment 2

[0049] This embodiment is used to illustrate the curbstone provided by the present invention and its preparation.

[0050] Mix 600g of ceramsite (average particle diameter is 7 mm), 12g of silicate and 10g of water to obtain a mixture that forms the bottom layer of the bottom plate and the bottom layer of the vertical plate; lay the mixture on the surfaces with water flow grooves and through both sides of the vertical plate In the through-hole steel curb bottom layer mold, solidify at 40°C for 500min to obtain the bottom layer of the bottom plate and the bottom layer of the vertical plate with an integrated structure. The thickness of the bottom layer of the bottom plate and the bottom layer of the vertical plate is 9cm, and the hole diameter is 5 mm and porosity are both 30%.

[0051] 600g silica sand (average particle diameter is 3mm), 12g waterborne polyurethane resin (Liaoning Nikkei Consulting Co., Ltd., F417505) and 0.24g toluene diisocyanate are mixed homogeneously, obtai...

Abstract

The invention provides a kerbstone, the kerbstone comprises a base plate and a vertical plate which enables vertical and upward extension from the base plate; an current groove is provided at the connecting part of the top surface of the base plate and side surface of the vertical plate along the length direction of the base plate; the kerbstone also comprises at least one permeable part; the base plate comprises a base plate bottom layer and a base plate top surface layer covered on the base plate bottom top surface, the vertical plate comprises a vertical plate bottom layer and a vertical plate side surface layer covered on the side surface of vertical plate bottom layer close to one side of the base plate; the base plate bottom layer and the vertical plate bottom layer are an integral body, the base plate top surface layer and the vertical plate side surface layer are an integral body; the base plate bottom layer, the base plate top surface layer, the vertical plate bottom layer and the vertical plate side surface layer have a porous structure, and the aperture diameters of a porous structure of the permeable part are respectively greater than the aperture diameter of the porous structure of the vertical plate bottom layer and the vertical plate side surface layer. The kerbstone has strong draining effect, thereby the foundation loosening can not be easily generated.

Description

technical field [0001] The present invention relates to a curb stone. Background technique [0002] At present, when building roads, especially for roads in cities, in order to facilitate the drainage of roads, drainage ditches are usually arranged below the ground on both sides of the road, and iron grates are set at the openings of the drainage ditches. When precipitation occurs, the water accumulated on the road will flow to both sides of the road, and flow into the gutter through the grate, and then enter the drainage system. [0003] However, this traditional drainage structure must be provided with a lot of iron grates at the opening of the drainage ditch to prevent foreign matter from entering the drainage ditch so that the drainage ditch is blocked, thereby causing a higher cost of the drainage structure. Moreover, the iron grate is prone to corrosion and other problems, and the iron grate is prone to defects after a long time, thereby reducing the strength of the i...
