Description

Concrete that permeates water fast flat curbstone

Technical Field

The utility model belongs to the town road field relates to a sponge urban road infiltration structure, in particular to concrete tie kerbstone that permeates water fast.

Background

The sponge city is a new generation of urban rainfall flood management concept, which means that the city has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters caused by rainwater and the like, and can be called as a water elasticity city. The sponge city adopts a method combining natural approach and artificial measures, and the supporting facilities can realize water absorption, water storage, water seepage and water purification in rainy days, and release and utilize the stored water when needed. With the advance of urbanization, the natural ecology of cities faces a serious imbalance. The urban pavement is hardened and paved by waterproof materials everywhere, so that the original natural ecological background and hydrological characteristics are changed, and therefore, natural permeation is enhanced and put in the first place. The method has the advantages that surface runoff can be avoided, the phenomenon that the hardened impervious pavement is converged into a municipal pipe network is reduced, meanwhile, underground water is conserved, the deficiency of the underground water is supplemented, the water quality can be purified through soil, and the urban microclimate is improved. The method for permeating the rainwater is various, and mainly changes various road surfaces and ground permeable paving materials to enable urban road surfaces to naturally permeate, adjusts the vertical direction of a green land, and reserves the rainwater from the source and then permeates.

In order to meet the rainwater infiltration requirement and improve the whole water permeability of the road, the flat curbstone made of pervious concrete is also used for improving the water permeability of the side of the road. Pervious concrete has a large number (15% to 35%) of interconnected voids. Like conventional concrete, it is made of a mixture of cement, coarse aggregate and water, however, it contains little or no sand, which results in a porous open-cell structure through which water can easily pass. When pervious concrete is used in municipal structures, it can rapidly absorb rain water at rates of 3 to 5 gallons per square foot of surface area, which exceeds the flow rates required to prevent runoff in most rainfall events. Rain water may be stored in a coarse gravel layer below the road surface or may penetrate into the soil below. The pervious concrete curbstones help prevent most of the polluting runoff that normally occurs on impervious pavements, since the pavement itself acts as a reserved area. However, the pervious concrete flat curbstone blocks rainwater on one side close to the road, the permeation area is only utilized on the side close to the road, the water seepage area is limited, after the pervious concrete flat curbstone is used for a long time, the permeability can be reduced, and when the precipitation is large, the permeation speed of the pervious concrete flat curbstone is insufficient, so that local water accumulation on the road surface can be caused, and the water accumulation on the road surface is drained into a municipal pipe network through a rainwater inlet, so that the soil water seepage rate is reduced.

Disclosure of Invention

The utility model aims to solve the current concrete tie kerbstone that permeates water infiltration area utilization ratio that permeates water is lower, and the infiltration rate is not enough can lead to surface ponding, and a large amount of rainwater passes through the problem that the inlet for stom water discharged municipal pipe network, provides a concrete tie kerbstone permeates water that permeates water fast, and make full use of permeates water in the concrete tie kerbstone, the synchronous infiltration of outer both sides, increases the infiltration area, improves infiltration efficiency, keeps more rainwater seepage in coarse sand gravel layer and the soil of road surface below.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a concrete that permeates water flat curbstone that permeates water fast, includes the flat stone with road surface parallel and level, and the middle part of flat stone makes progress the arch and is provided with longitudinal extension's curbstone, and flat stone and curbstone adopt the concrete material integrated into one piece that permeates water, its characterized in that: use as the inboard towards road one side, the road one side of being the outside dorsad, the drainage groove has been seted up to the flat stone upper surface of kerbstone lateral side, and longitudinal extension is followed in the drainage groove, the bottom of kerbstone is transversely pre-buried and is provided with the drainage tube of the inside and outside both sides of intercommunication kerbstone, the bottom surface of flat stone is equipped with the earial drainage passageway.

When the lateral side of the drainage groove is required to be provided with facilities such as sidewalks, the erection plate can be erected on the horizontal step surface and then constructed above the erection plate, and the structure of the drainage groove can be effectively reserved.

Preferably, the drainage groove is a trapezoidal groove with a large upper part and a small lower part. The trapezoidal groove is convenient for prefabricating and demoulding.

Preferably, the drain channel is an upwardly concave arcuate channel. The arch-shaped groove has good structural strength and can effectively maintain the supporting strength.

Preferably, the end faces of the flat stone and the curbstone are flush, the flat stone and the curbstone form an integrally formed flat curbstone, the length of the flat curbstone is 0.5-2m, and 1-2 drainage tubes are pre-buried in each flat curbstone.

Preferably, the flat curbstones abut against and are spliced on the lateral end faces of the road, and rainwater openings are formed between the adjacent flat curbstones every 20-30 meters.

Preferably, the drainage groove and the drainage channel are both connected with the rainwater port in an open mode. After the flat curbstone is installed, the drainage grooves and the drainage channels are connected in series in sequence and are communicated to the rainwater inlet. When the precipitation is large, the drainage groove and the drainage channel can be used as auxiliary drainage pipelines to drain rainwater into the rainwater port.

The utility model discloses a concrete flat curbstone permeates water, through horizontal pre-buried drainage tube and the vertical drainage groove structure in the outside, the flat stone infiltration area of the inside and outside both sides of make full use of curbstone improves effective infiltration area, and infiltration with higher speed, more keep somewhere the rainwater infiltration in gravel and the soil of road below, reduce through inlet for stom water exhaust rainwater proportion, also reduce road surface rainwater to be detained through improving infiltration efficiency as far as possible simultaneously.
