Abstract
A kind of efficient water drainage curb, comprises road kerb body, parallelly on road kerb body offers the drain hole that water (flow) direction is tended at multiple angle of inclination, all offers air equalizer opening above each drain hole; The sidewall of drain hole and road axis between angle a be 45 ° ~ 53 °.The efficient water drainage curb that the utility model provides, can solve the problem that drainage efficiency is low, substantially increase the drainage efficiency of drainage rock.
Description
Technical field
The utility model relates to a kind of water drainage curb, especially a kind of efficient water drainage curb.
Background technology
These several years, a lot of urban waterlogging of China was very serious, and the draining of underground pipeline is saturated to cause the main cause of this present situation to be, thus causes the large area ponding on ground.But when amount of precipitation is not very large, within the drainability of subsoil drain, there is large-area excess surface water equally, by analysis, find that main cause is that existing curb drainage system does not give full play to its maximum functionality, especially water drainage curb drainage efficiency is not high.In road drainage system, the drain hole of existing curb draining kerbstone is perpendicular to road kerb front surface (namely the angle of road kerb drain hole axis and road axes is 90 degree), and for the road that longitudinal gradient is larger, the single poor efficiency of angle, is unfavorable for surface drainage.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of efficient water drainage curb, can solve the problem that drainage efficiency is low, substantially increase the drainage efficiency of drainage rock.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of efficient water drainage curb, comprises road kerb body,
Parallelly on road kerb body offer the drain hole that water (flow) direction is tended at multiple angle of inclination, above each drain hole, all offer air equalizer opening;
The sidewall of drain hole and road axis between angle a be 45 ° ~ 53 °.
Air equalizer opening is opened in the middle of the cross section of drain hole.
Road kerb body length is 1m, width is 0.2m, highly for being 0.25m, the quantity of drain hole is four.
The efficient water drainage curb that the utility model provides, on the basis of existing water drainage curb, by being optimized the drain hole angle of water drainage curb, make the drain hole angular slope after improving and optimizating in water (flow) direction, be of value to draining, improve the drainage efficiency of drainage rock admirably; The design balance of air equalizer opening road kerb inner and outer air pressure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is that the A-A of the utility model Fig. 2 is to sectional view;
Fig. 4 be to different drain hole sidewalls and road axis between angle a test and show that a is 45 ° ~ experimental data curve map that 53 ° of drainage efficiencies are the highest.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of efficient water drainage curb, comprises road kerb body 3,
Parallelly on road kerb body 3 offer the drain hole 1 that water (flow) direction is tended at multiple angle of inclination, above each drain hole 1, all offer air equalizer opening 2;
The sidewall of drain hole 1 and road axis between angle a be 45 ° ~ 53 °.
Air equalizer opening 2 is opened in the middle of the cross section of drain hole 1.
Road kerb body 3 length is 1m, width is 0.2m, highly for being 0.25m, the quantity of drain hole 1 is four.
The utility model be to existing water drainage curb by making the modeling experiment of different angles, change drain hole 1 sidewall and road axis between the size of angle a draw.
Experiment obviously can change the drainage efficiency of drain hole 2 after finding the optimization of drain hole 1 Sidewall angles, finally carry out a large amount of contrast experiments and show that optimum optimization angular interval is 45 ° ~ 53 °, experimental data curve as shown in Figure 3.
Data analysis by experiment, when road gradient 2%, 3%, 5%, the drainage efficiency after optimization is relative to the raising respectively 8%, 20% and about 30% do not optimized, and improved effect is obvious.
The course of work of the present utility model is as follows:
After rainfall, the longitudinal gradient on road surface and the guiding function of crown slope, make rainwater collect to both sides curb, then enter sewer pipe by draining.Due to the flow direction of current and drain hole 1 towards at 45 ° ~ 53 °, be acute angle, drainage efficiency is high.
The efficient water drainage curb that the utility model provides, on the basis of existing water drainage curb, by being optimized the drain hole angle of water drainage curb, make the drain hole angular slope after improving and optimizating in water (flow) direction, be of value to draining, improve the drainage efficiency of drainage rock admirably; The design balance of air equalizer opening road kerb inner and outer air pressure.
