Embodiment approach

[0026] Such as figure 1 with figure 2 As shown, when there is less accumulated water in the road, most of the accumulated water can directly flow into the water flow trough, or first penetrate into the floor surface layer and / or the riser surface layer, and then flow into the water flow channel. When there is a lot of accumulated water in the road, the accumulated water cannot be discharged in time only through the water flow groove, and the road water may overflow the water flow groove; therefore, preferably, the bottom position of the water permeable part is not Higher than the top surface of the bottom plate. When the stagnant water in the water runner flows over the water runner, it can also be smoothly discharged from the water permeable part. According to the present invention, it is only necessary to ensure that the pore diameter of the porous structure of the permeable part is larger than the pore diameters of the porous structure of the bottom layer of the vertical pl...

Embodiment 1

[0043] This example is used to illustrate the curb stone provided by the present invention and its preparation.

[0044] Mix 1000g of perlite (average particle diameter of 3.5 mm), 100g of cement and 100g of water to obtain a mixture forming the bottom layer of the bottom plate and the bottom layer of the vertical plate; the mixture is laid on the channels with water flow grooves and through the two sides of the vertical plate. The steel curb bottom layer mold of the hole was cured at 40°C for 500 minutes to obtain an integral structure of the bottom bottom of the bottom plate and the bottom of the vertical plate. The thickness of the bottom of the bottom plate and the bottom of the vertical plate are both 10cm, and the hole diameter is 0.5 mm. The porosity is 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 bottom sur...

Embodiment 2

[0049] This example is used to illustrate the curb stone provided by the present invention and its preparation.

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

[0051] 600g of silica sand (average particle diameter of 3mm), 12g of water-based polyurethane resin (Liaoning Nikkei Consulting Co., Ltd., F417505) and 0.24g of toluene diisocyanate were mixed uniformly to obtain a mixture of the floor surface layer and the vertical plat...

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 invention relates to a curb. Background technique [0002] At present, when constructing roads, especially for roads in cities, in order to facilitate the drainage of the road, drainage ditches are usually set below the ground on both sides of the road, and iron grate is set at the opening 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 drainage ditch through the grate, and then enter the drainage system. [0003] However, in this traditional drainage structure, many iron grate must be installed at the opening of the drainage ditch to prevent debris from entering the drainage ditch and block the drainage ditch, resulting in high cost of the drainage structure. Moreover, the iron grate is prone to corrosion and other problems. Over time, the iron grate is prone to defects, which reduces the strength of the iron grate. The grate is damaged. In addition, in the tr...
