Due to the novel catchwater grid structure, the noise pollution is reduced, the possibility that the road surface is damaged and sunk is reduced, and the maintenance is convenient.
Description
Technical field
The utility model relates to road ditch, is specially a kind of novel catchwater cell structure.
Background technology
Traditional catchwater grid generally adopts steel grating and steel socket, and steel socket is arranged on steel concrete side wall, and steel grating is welded on steel socket.There is following defect in this structure:
1. under the rolling for a long time of heavy vehicle, often occur that steel grating damages the situation that distortion, grid and base solder joint come off.When there being vehicle will mutually clash into through steel grating and steel socket, send the sound of " crash when crash when ", cause near noise resident's rest impact that disturbs residents.
2. there is elevation difference in grid and road surface, cannot smooth-goingly be connected, and vehicle rolls grid unbalance stress, thereby road-ability is poor and easily cause grid to sink or projection causes grid edge road surface breakage.
3. maintain and replace grid, needs cast-in-situ steel reinforced concrete boundary belt, needs a curing time more than week after having constructed, and ability open to traffic is larger to traffic impact.
Therefore, be necessary traditional catchwater grid to improve.
Utility model content
The purpose of this utility model is to provide a kind of novel catchwater cell structure, to reduce noise pollution, reduces the possibility of road surface breakage and sinking, and easy to maintenance.
For achieving the above object, the utility model is by the following technical solutions:
A kind of novel catchwater cell structure, be located on the steel concrete side wall of road surface, comprise grid, bituminous texture layer, two spacing angle bar and some securing members, two described spacing angle bar are locked on the side wall of steel concrete both sides by securing member, described bituminous texture layer is layed in both sides side wall end face, two spacing angle bar are embedded in bituminous texture layer, described grid comprises grid body, grid body both sides are provided with flange form upper disk surface, both sides, bottom are provided with spacing leg, described spacing leg socket joint enters in two spacing angle bar, described flange form upper disk surface and bituminous texture layer consolidation, and be positioned at same plane with road surface.
Wherein, described grid is that the pouring of ductile iron entirety is structure as a whole.
Wherein, described securing member is expansion bolt.
Between described flange form upper disk surface and spacing leg, be provided with some reinforcing ribs.
Adopt after above technical scheme, the utlity model has following beneficial effect:
1. flange form upper disk surface is rolled and will be embedded flexible pavement together with grid body by road roller, form Unified Global with road surface, load pressure from top is dispersed in the road surface structare layer of both sides by flange form upper disk surface, the load that catchwater side wall bears is reduced more than 80%, reduce the possibility of grid edge Damages of Asphalt Road Surface and sinking.
2. the connected mode of grid and side wall adopts spigot-and-socket, has changed the mode of traditional grid and the cast-in-place combination of side wall, even if use socket fitting type structure grid to occur sedimentation under vehicular load repeated action, also can adjust at any time height of grid; Use socket fitting type structure also to change the way that traditional grating well cover adds base, ductile iron grid is directly embedded in flexible pavement, and flexible pavement plays the effect of flexible buffer, thereby while having avoided vehicle through grid, rolls the noise of generation.
3. spacing angle bar is arranged on the side wall of catchwater both sides by expansion bolt, plays restriction grid installation site and avoids constructing medium pitch leakage.
4. grid adopts ductile iron integral cast to be structure as a whole, and bearing capacity is stronger.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, the utility model discloses a kind of novel catchwater cell structure, be located on road surface steel concrete side wall 50, it comprises grid 10, bituminous texture layer 20, two spacing angle bar 30 and some securing members, and the securing member of the present embodiment is expansion bolt 40.
As Fig. 2 shows, grid 10 comprises that grid body 11, grid body 11 both sides are provided with flange form upper disk surface 12, and both sides, bottom are provided with spacing leg 13, and grid 10 is that the pouring of ductile iron entirety is structure as a whole, ductile iron integral cast, makes the bearing capacity of grid 10 stronger.Between flange form upper disk surface 12 and spacing leg 13, be provided with some reinforcing ribs 14, to improve the bulk strength of grid 10.
When use, first cut road surface, spacing angle bar 30 use expansion bolts 40 are locked on steel concrete side wall 50, play restriction grid 10 installation sites and avoid constructing medium pitch leakage.Then steel form is installed, on both walls end face construction area, is sprayed mulseal, layering forms bituminous texture layer 20 after filling compacting pitch.Then vertically steel form is carefully pulled out, careful grid 10 vertically socket joint is entered in the bituminous texture layer 20 on side wall, socket joint inserts in the spacing width of two spacing angle bar 30 with spacing leg 13, centre is pitch filleting, this structure does not directly contact spacing leg 13 with spacing angle bar 30, bituminous texture layer 20 plays the effect of flexible buffer, thereby while having avoided vehicle through grid 10, roll the noise of generation, even if grid 10 occurs sedimentation under vehicular load repeated action, also can adjust at any time grid 10 height.Finally roll grid 10 is closely embedded in bituminous texture layer 20 by road roller, grid body 11 and flange form upper disk surface 12 and road surface same plane, flange form upper disk surface 12 is distributed to the load pressure from top in the road surface structare layer of both sides by flange face, the load that catchwater side wall bears is reduced more than 80%, reduce the possibility of grid 10 edge Damages of Asphalt Road Surface and sinking, and because seamless connection is realized on grid 10 and road surface, road-ability is good, can effectively prevent the phenomenons such as grid 10 road surface, edge scarifyings, cracked, damage.
When the maintenance of this cell structure, only need grid 10 is prized to pine and vertically lift with simple machine, after filling appropriate pitch, flange form upper disk surface 12 bottoms offset compacting with road roller, quick construction, can construct at dead of night complete is open to traffic, little on the impact of traffic.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
