This technical scheme is through setting up double -deck grate structure, and the lower floor is the cell type that adopts the manufacturing of high strength steel muscle concrete structures of twining, the mainly used bearing, and the panel structure of upper strata for adopting the manufacturing of rubber granule concrete has certain elasticity, and mainly used bears the vehicle and rolls, such structure has also reached and has reduced the effect that the vehicle rolled the noise when satisfying rainwater grate load bearing stength, still can reach the grate vibrations when reducing to be rolled by the wheel.
Description
Technical field
The utility model belongs to urban road facility technical field, relates to urban road sewer drainage system, especially relates to a kind of double-deck rain grid structure.
Background technology
Unimpeded for ensureing the draining of town road, usually at the sewer mouth of road edge, rain grid is installed, by urban sewerage and drainage system, rain sewage is discharged road, ensure that urban road is unobstructed.The rain grid used in current China town road is of a great variety, and main Types has the types such as concrete rain grate, polymer matrix composite rain grid, ductile iron rain grid, steel fibre reinforced concrete rainwater grid.
Along with Urbanization in China is constantly accelerated, Reconstruction of City Road constantly rises, and the demand of rain dirty engineering in city to catch-basin, rain grid increases day by day, and requires also more and more higher to the function, quality etc. of rain grid.Traditional rain grid is generally reinforced concrete structure, although intensity is high, but the rigidity of its integral material is larger, again because mounted drain cover generally all exists certain height difference with road plane, make vehicle pass through rain grid time easily produce vehicle body and beat and noise, have impact on stability and the comfortableness of driving, too increase vehicle vibration to the wearing and tearing of rain grid and destruction.
Utility model content
In order to solve the problem, the utility model provides a kind of double-deck rain grid structure, thus reach higher than common rain grid intensity, noise is little, good springiness, life-span are long effect.
The utility model is achieved by following technical solution.
A kind of double-deck rain grid structure, comprise pedestal, also comprise the grate main body be arranged on described pedestal, described grate main body comprises grate lower floor and grate upper strata, described grate lower floor is slotted disk shape, described grate upper strata is nested in grate lower floor, and grate upper strata and grate lower floor are respectively equipped with the upper limbers and lower limbers that communicate.
Further, the face, hole of described lower limbers is greater than the face, hole of limbers, and lower limbers and upper limbers are axially aligned.
Further, described lower limbers and upper limbers are strip.
Further, be provided with perpendicular to lower limbers bearing of trend the reinforcing rib running through grate lower floor two sides in the middle part of described lower limbers.
Further, the diameter of section of described reinforcing rib is at least the half of grate lower floor bottom thickness, and reinforcing rib quantity is at least 2.
Further, described grate lower floor adopts high strength reinforced concrete manufacture.
Further, described grate upper strata adopts the manufacture of rubber grain concrete.
The beneficial effects of the utility model are:
The double-deck rain grid structure of one described in the utility model, by arranging double-deck grate structure, lower floor is the grooved dish structure adopting high strength reinforced concrete to manufacture, be mainly used in load-bearing, upper strata is the panel construction adopting rubber grain concrete to manufacture, there is certain elasticity, be mainly used in bearing vehicle and roll; Such structure, while meeting rain grid load bearing stength, also reaches and reduces the effect that vehicle rolls noise, and also can reach the grate reduced when being rolled by wheel and shake, its intensity is high, good springiness, good endurance, longer service life.

Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Fig. 1 ~ 5, the double-deck rain grid structure of one described in the utility model, comprise the pedestal 4 being fixedly installed in road surface sewer mouth, also comprise the grate main body 5 be arranged on described pedestal 4, described grate main body 5 comprises grate lower floor 1 and grate upper strata 2, described grate lower floor 1 is slotted disk shape, and described grate upper strata 2 is nested in grate lower floor 1, and grate upper strata 2 and grate lower floor 1 are respectively equipped with the upper limbers 201 and lower limbers 101 that communicate; Grate main body 5 can be taken off from pedestal 4, and grate upper strata 2 can not from grate lower floor 1 in overall pulling down.
Described lower limbers 101 and upper limbers 201 are strip, the face, hole of lower limbers 101 is greater than the face, hole of limbers 201, and lower limbers 101 is axially aligned with upper limbers 201, when rainwater flows into from upper limbers 201, because the face, hole of lower limbers 101 is larger, make not hinder in hole path, can be unblocked.
Owing between the end face of lower limbers 101 being the stress concentration point of grate lower floor 1, the most easily rupture, therefore in the middle part of lower limbers 101, be provided with perpendicular on the bearing of trend of lower limbers 101 reinforcing rib 3 running through grate lower floor 1 two sides, solid and reliable to guarantee grate lower floor 1; The diameter of section of reinforcing rib 3 is at least the half of grate lower floor 1 bottom thickness, and reinforcing rib 3 quantity is at least 2, and reinforcing rib 3 adopts round steel cutting herein.
Described grate lower floor 1 adopts high strength reinforced concrete manufacture, is mainly used in load-bearing; Described grate upper strata 2 adopts the manufacture of rubber grain concrete; there is good elasticity, be mainly used in bearing wheel and roll, grind the out-of-date effect playing damping, noise reduction at wheel; compare the rain grid of conventional reinforced concrete structure, there is better resistance to pressure and abrasion resistance.
During installation, first pedestal 4 be fixedly mounted on the other sewer mouth of road and ensure concordant with pavement of road, then the grate upper strata 2 of grate main body 5 is installed in pedestal 4 upward, rap surrounding to compress and can complete installation, simple to operation, do not steal value, without the need to special anti-theft device or structure; When rain flows into sewer from upper limbers 201, due to large little under double-hole, be not vulnerable to resistance and even block; When wheel roll from grate upper strata 2 out-of-date; because grate upper strata 2 is for having the manufacture of flexible rubber grain concrete; buffering can be formed to wheel; reduce the vibrations of grate lower floor 1; thus reduce the noise that wheel grinds out-of-date generation; improve the colleague in the application life of grate, also improve the comfortableness of vehicle driver and crew.
