Abstract
The utility model relates to a rainwater reserving structure between terraced slopes in a mountainous city. The rainwater reserving structure comprises the terraced slopes (5) and an inter-slope rest platform (1). A passageway (3) which connects the upper terraced slope (5) with the lower terraced slope (5) is arranged in the middle of the inter-slope rest platform (1). Water storage ponds (2) are dug in the two edges of the passageway (3). Small water drain holes (4) which are communicated with roadside green belts are formed in the bottom faces of the water storage ponds (2). The scale height of the passageway (3) is larger than that of the water surface of each water storage pond (2). The rainwater reserving structure has the advantages that running rainwater in the initial stage can be accumulated and reserved, and therefore peak hours of rainwater running in the city can be staggered, the amount of running rainwater entering the drain network of the city can be reduced in the raining process, and the problems of rainfall flood and waterlogging in the city caused by rainfall can be solved.
Description
Technical field
The utility model belongs to rain flood control technology field, and the rainwater that lamps structure relates between the ladder of slope, a kind of Mountainous City is detained structure.
Background technology
Along with the continuous expansion of China's city size, there is huge variation in land use pattern, has occurred a large amount of waterproof earth's surfaces, makes the formed run-off of Urban Rain much larger than the past at present.Because existing planning in design, urban discharging pipeline lags behind, the problem that design standard is on the low side, cause the existing discharge structure system in a lot of cities cannot adapt to the requirement of Quick drainage, along with the frequent appearance of extreme weather in recent years, city waterlogging problem is also day by day serious.
Slope ladder is laid form as a kind of major road of relief larger area, particularly common in Mountainous City.Slope ladder half space and step distribute alternately, its effect is only for walking for people and changing direct of travel, if but fully develop the potentiality that ladder half space in slope is received aspect delay to holding of rainwater in rainfall, and just can reduce urban road run-off, reduction flood frequently occurs.
Utility model content
The road slope ladder extensively existing for Mountainous City, the rainwater that technical problem to be solved in the utility model is just to provide between the ladder of slope, a kind of Mountainous City is detained structure, it can rely between the ladder of slope half space to hold to receive delay rainfall runoff, reduces the urban road run-off forming in rainfall.
Technical problem to be solved in the utility model is to realize by such technical scheme: it includes half space between slope ladder and ladder, between this ladder, in the middle of half space, be provided with the passageway that connects uphill, downhill ladder, both sides, passageway digging has the water storage pool, and the sluicing aperture that passes into roadside greenbelt is equipped with in bottom surface, the water storage pool.
Owing to having adopted technique scheme, in rainfall, the rainwater landing on road slope ladder and half space confluxes in the water storage pool and is temporarily stored in this under the discrepancy in elevation and Action of Gravity Field, and then, through the water conservancy diversion of earial drainage aperture, slowly earial drainage is to the greenbelt of roadside.Thereby having realized holding of rainfall runoff receives and is detained and shifts.
The utlity model has following advantage: can hold to receive and be detained initial rainfall runoff and realize avoiding the peak hour of urban rainfall runoff, can alleviate the flow mode that enters urban drainage pipe network in rainfall again, alleviate Urban Storm Flood and the waterlogging problem because of rainfall, brought.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model.
In figure: 1. slope ladder half space; 2. the water storage pool; 3. passageway; 4. sluicing aperture; 5. slope is terraced.
lamps structure embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, the utility model includes half space 1 between slope ladder 5 and ladder, is provided with the passageway 3 that connects uphill, downhill ladder 5 between this ladder in the middle of half space 1, and passageway 3 both sides diggings have the water storage pool 2, and the sluicing aperture 4 that passes into roadside greenbelt is equipped with in 2 bottom surfaces, the water storage pool.
Above-mentioned passageway 3 absolute altitudes are higher than the absolute altitude of the water storage pool 2 waters surface, make under full water state the interior rainwater absolute altitude in the water storage pool 2 lower than passageway 3.
In rainfall, the water storage pool 2 full water depth of waters are about 8-15cm, and sluicing aperture 4 diameters are 3-4cm.
Operating principle of the present invention is: after rainfall, relation due to the gradient between the ladder of slope, under the effect of the rainwater landing on slope ladder 5 and half space 1 at gravity, conflux and store the water storage pool 2 to being arranged on half space 1, passageway 3 is run through in the middle of the water storage pool 2, upper and lower two the slope ladders 5 that connect half space 1, guarantee current not hindering under the state of the water storage pool 2 full waters.
Sluicing aperture 4 is positioned at bottom, the water storage pool, and the rainwater collecting in the water storage pool 2 is guided in greenbelt, has expanded the retaining volume on the water storage pool 2.
Claims (3)
1. the rainwater between the ladder of slope, a Mountainous City is detained structure, it is characterized in that: include half space (1) between slope ladder (5) and ladder, in the middle of half space between this ladder (1), be provided with the passageway (3) that connects uphill, downhill ladder (5), both sides, passageway (3) digging has the water storage pool (2), and the sluicing aperture (4) that passes into roadside greenbelt is equipped with in bottom surface, the water storage pool (2).
2. the rainwater between the ladder of slope, Mountainous City according to claim 1 is detained structure, it is characterized in that: described passageway (3) absolute altitude is higher than the absolute altitude of the water storage pool (2) water surface.
3. the rainwater between the ladder of slope, Mountainous City according to claim 2 is detained structure, it is characterized in that: the described water storage pool (2) degree of depth is 8-15cm, and sluicing aperture (4) diameter is 3-4cm.
