Abstract
The invention relates to a street grid (1) for surface drainage. Said grid consists of a frame (10) and a grating (11), which are adapted to the contours of a paved gully in order to be integrated into the latter, for draining water that flows towards the street grid in a pre-defined direction. The aim of the invention is to ensure permanent drainage. To achieve this, recessed inlet openings (13) are provided in the upper edge of at least one lateral wall of the frame that guides the water in the flow direction.
Description
Technical field
The present invention relates to a kind of street grid of surface drainage, comprise a framework and fence, this framework and fence are installed in the irrigation canals and ditches of paving that profile adapts with it, make water flow to the street grid with predetermined direction, thereby reach the purpose of draining.
Background technology
As everyone knows, according to routine, the street grid of described surface drainage is to install like this: framework surface and fence surface are contour with the top edge of the irrigation canals and ditches of paving.Water such as the snow-broth of rainwater and thawing, can flow to the grid in the irrigation canals and ditches, and the framework of flowing through then enters the street drainage system by fence.The realization of another kind of street grid is to suppose that the water that flows to grid at first flows into framework and fence, has only when influx increases to turn to via fence then.
Street grid in the existing channel shape may occur that in practice: after building up a water stream channel, and for example a walkway or irrigation canals and ditches made of stones, it has the sinking degree different with the street grid.Because earth construction has unpredictable feature, such as overload or design weak point is arranged, these different sinkages are inevitable to a certain extent.If the top edge of grid frame is higher than the water stream channel bottom, the water that flows into via passage can not fully clear, and cause water that the top edge of grid frame is stopped up, thereby can form residual puddle in the surface of water stream channel and vicinity.
Not only all there are a lot of problems in these residual puddles for the pedestrian but also to wagon flow, and danger close.In addition, they can cause the infringement to drainage system usually.If the water in the puddle has freezed, can produce very huge pressure, especially in the junction of water stream channel and neighbouring surface, such as on a sidewalk, these pressure can make the crack of junction enlarge, and the base plate of whole water stream channel is unclamped, so that last total is destroyed.And these sedimentations place can make the solid matter in the water, such as leaf, pollen or scattered fragment, can not be flushed away fully and deposit in the edge of street grid frame.Especially at water at first under situation about flowing through between framework and fence, because these suspensions in the dead angle can only could remove with hand or big pressure, so can cause the grid obstruction very soon.The process that the oneself removes is contingent hardly.
Summary of the invention
The objective of the invention is to develop a kind of foregoing street grid, can guarantee the normal operation of drainage system for a long time.
The object of the present invention is achieved like this: the foregoing street grid that is used for surface drainage, form by framework, and can introduce fluid at a sidewall of framework at least, so it comprises the framework water inlet that is embedded in the framework top edge.
The street grid of drainage system of the present invention has very large advantage.Drainage system no longer requires the top edge of framework must be accurately to maintain an equal level with the bottom of water stream channel or a little less than the water stream channel bottom.Because water also can be by framework the water inlet of top edge flow into, even when being lower than street grid top edge in the bottom of water stream channel, water can also continue to flow into drainage system.Under this water inlet and the different situation of street grid horizontal plane, the performance of drainage system no longer is limited.Therefore the problem that is formed by residual puddle no longer causes any danger, because water can not accumulate at the edge of street grid with in because of the pit that sinks to forming, but the recess drainage of top edge that can be by the street grid frame.As a result, not only increased the application life of water stream channel, and this design principle saved a large amount of expenses equally, such as the expense of repairing, cleaning, sanitary fittings or reconstruction.Even when water stream channel occurred sinking, water still can must flow away smoothly, has avoided the situation that water diffuses out before the grid of street.
In addition, enter in the device of street grid via the top edge of framework and fence at water, the risk that grid stops up has also reduced, and does not stop up drainage system because solid matter can not deposit between framework and fence, and the reliability of work obviously increases.
The design of water inlet can be selected arbitrarily according to performance and structure.Certainly, it is particularly advantageous building the water inlet that caves in the place of framework and grid needs simultaneously.The reduction of its highly significant the risk stopped up of the water-carriage system that causes by solid matter or stickiness particle, when the fashionable meeting of a large amount of next time current washes away solid sediment.By external factor or mechanism, the stone of bringing into such as the pedestrian, and cause the obstruction of water inlet, its cleaning is equally quite simple.
Because be easy to enter cleaning from top, usual street cleaning just can make the water inlet of obstruction unimpeded once more.
It is very favorable equally that the water inlet of fence and framework tilts towards inside.It has guaranteed that water effectively flows into, because water is very slow when flowing into grid sometimes, this structure has been quickened the speed that water flows into grid, has therefore prevented the precipitation of solid matter.
Another favourable design of the present invention is by fence and the design of framework water inlet are realized in the middle zone of departing from of water stream channel bottom.Because in the middle of the fastening devices on the fence was arranged on usually, so design can prevent earth effectively.And, a fixing net of use often need be set in the jackshaft position of fence, when water inlet away from jackshaft, described fence does not just need to carry out the reconstruction of costliness.It has reduced fabricating cost effectively and range of application widely is provided.
The street grid of another structure of the present invention, its bottom is oval-shaped or circular structure.In this case, abundant lateral inflow mouth is evenly distributed in the circumference place of grid.This street grid especially is used in two or more water stream channel intersection.When water flows in the zone of street grid, these water stream channels usually enlarge and form a kind of basin, the position at this foregoing just sedimentation place is owing to the zone in basin is very big and because the current of different amounts form the one-sided flow overburden of part through passage.Like this, become simply with regard to the mutual adaptive problem of the passage that makes differing heights, because the slight difference of channel height is an acceptable.In addition, the street grid can also have other any shapes.Because the position of water inlet is at the side of framework, residual puddle also may draining under such as the situation of the street grid of rectangle inclined plane shape.
Of the present invention another be characterised in that, makes the degree of depth and the expected maximum settlement degree of water stream channel of water inlet of framework and fence be complementary.Sedimentation degree size depends on externalities, such as the structure of earth, and climatic influences, the perhaps overburden that causes of traffic, the sedimentation degree is widely different usually.The expert sometimes can be in advance do an approximate calculation to the sedimentation of expection, and the degree of depth of water inlet that then can be by regulating fence and framework makes it accurately to be fit to environment at that time.Particularly when laying water stream channel with smooth stone, too dark water inlet may wash away the material of passage supporting layer below.Because the degree of depth that can regulate water inlet, this problem has also just solved.
The present invention further advantage illustrates in the dependent claims.

The specific embodiment
In the following description, the identical part or the part of same function are represented with identical Reference numeral.
Fig. 1 is that the axle that waits of a street grid 1 is schemed, and comprises a framework 10 and a fence 11 that embeds framework 10.The top edge of framework top edge 12 and fence 11 as shown in Figure 1, draws at framework 10 on the sidewall of inlet flow direction on same plane, and framework water inlet 13 is formed at framework top edge 12 places, and is promptly recessed in framework.The fence water inlet 14 that has respective shapes on the fence 11.In first embodiment of the invention, fence water inlet 14 is installed in the end face of street grid 1, abuts against adjacent draining input water stream channel 2.In normal circumstances, the water that the flows to grid top edge of framework top edge 12 and fence 11 of flowing through earlier enters the street grid again.If now water stream channel 2 occurs sinking, for example because the sedimentation that regular overburden or braced structures can't reckon with, the water of flowing through still can flow into the street grids by framework water inlet 13 and fence water inlet 14.As a result, even because of sedimentation forms lowland, drainage system still is guaranteed.Water forms the risk in so-called residual puddle against framework top edge 12 backwashes, be eliminated like this.In addition, enter the inside of street grid because of the water of flowing through process framework water inlet 13 and fence water inlet 14, so just can not stay solid matter and passage.
Fig. 2 is the vertical view of first embodiment as shown in Figure 1.Can be clear that from Ben Tu framework water inlet 13 and fence water inlet 14 are installed in the zone of channel bottom 3.Water inlet is installed in that to depart from the center be very rational, because generally (as shown in Figure 2) fence 11 comprises a central net 15 that plays fixation.Because water inlet 13,14 is installed on off-centered position, the braced structures of fence 11 does not need to revise on the one hand, makes the parts in the existing fence 11 can prevent dirt on the other hand.
Fig. 3 is the front view of first embodiment as shown in Figure 1.It has shown the structure of the framework water inlet 13 and the fence water inlet 14 of upward opening.This embodiment has reduced drainage system to a great extent because residual puddle and blocked risk.Because the shape that this is suitable for hydraulic pressure makes the solids that flows into gutter be difficult in water inlet 13,14 and assembles.Certainly, this has not only reduced the risk that drainage system stops up owing to residual puddle, and, strengthened functional reliability on the whole and be easier to safeguard drainage system because solid matter can not be deposited in the framework water inlet 13 and the fence water inlet 14 of upward opening.As everyone knows, the alluvial meeting of a spot of solid precipitation causes the obstruction of whole system very soon, because the sedimentary deposition of the solid that these a spot of precipitation surface help flowing into subsequently.In addition, drainage system equally also can thereby cause owing to the former of outside stopping up.For example, vehicle of passing by and pedestrian can bring the fragment of stone and trees into street grid 1, and this often is the reason that forms this type of obstruction.The advantage of present embodiment also is, if water inlet blocks, promptly uses traditional cleaning street water inlet 13,14, and it is clean also to be easy to cleaning.Clean because in cleaning course, hand can be put in, though do not need usually.
Fig. 4 is the sectional view of first embodiment along IV-IV line among Fig. 2.Can it is evident that from figure framework water inlet 13 and fence water inlet 14 are corresponding downward-sloping towards inside.This can form very effective flow, because water is understood pick up speed when flowing through the street grid, thereby has hindered the precipitation of solid matter.
Fig. 5 to Fig. 7 is another embodiment about street of the present invention grid 1.This street grid 1 basic structure is circular.In this embodiment, abundant framework water inlet 23 and fence water inlet 24 are evenly distributed on this circumference.Same, the water that pours in flows into grid 1 inside, street by the top edge of framework top edge 22 and fence 21.This street grid 1 is used for situation about flowing into from two or more water stream channel 2 when water.This embodiment guaranteed owing to sink or design flaws, and causes different water stream channel 2 to be in different planes, and the draining in the street grid 1 still is guaranteed.Therefore, use this street grid 1, make become very simple of the construction of system, and undoubtedly must reduce the danger that forms because of residual puddle.These all can produce involved advantage among described first embodiment.
