Abstract
The utility model discloses a double-pool type accident pool for road leakage, comprising a slow flow pool and an emptying pool communicated with a water outlet at the lower part of the slow flow pool. The slow flow pool is communicated with a water outlet on the rod surface, and is internally provided with slow flow cavities which are arranged in parallel along the water draining direction and are formed by the dividing of at least one slow flow baffle, and the slow flow baffle is provided with a throttle hole along the water draining direction. In the utility model, a structure combining the slow flow pool and the emptying pool is adopted, when leakage accident occurs on the road suddenly, accident water flows into the slow flow pool firstly, the structure of the slow flow pool results in the slow flowing of the accident water, the accident pool is used for storing the accident water (liquid) temporarily so as to help persons handling the accident to obtain time for site processing, and slow down the spreading of toxic and harmful substances, thus effectively protecting water resources and surrounding environment; simultaneously, the accident pool precipitates rainwater, regulates and stores rainwater when in rainstorm, and decreases the peak flow of water discharged to downstream; and the double-pool type accident pool for the road leakage has simple structure and low construction cost, and is easy for maintenance.
Description
Technical field
The utility model relates to a kind of highway supporting facility, and particularly a kind of highway leaks two ponds formula accident pool.
Background technology
Highway is owing to have stronger flexibility, thereby more and more becomes pillar of economy.Along with market economy increasing development, highway mileage constantly increases, and particularly speedway is especially to promoting that local development plays irreplaceable effect.Because the flexibility of highway itself is inevitably by water body and conservation of nature zone.The highway transportation of chemical substances such as poisonous and harmful also is a means of transportation comparatively efficiently.These danger are poisonous, hazardous substances has constituted a potential threat that tool is big to water body and conservation of natural environment.And transportation has big possibility generation leakage, if poisonous, the hazardous substances polluted-water of leakage just may cause the downstream resident to poison, urban water supply is interrupted, and causing than great society influences.
In the prior art, for poisonous, the hazardous substances that prevents to leak pollutes natural environments such as water sources, highway operated by rotary motion accident pool, the accident pool normality is in emptying state, when having an accident, by manually the surface drainage water route being switched to accident pool.When accident took place, scene of the accident personnel can initiatively not go to switch the draining water route of highway in the practice, and the highway administration personnel reach the spot and switch hysteresis on can time of occurrence, and poisonous and harmful substance is entered in water source or the environment, cause negative consequence.
Therefore, need improve existing highway accident pond, during burst leakage accident on occurring in highway, can alleviate the diffusion of poisonous and harmful substance, and be used for temporarily storing accident water (liquid), provide buffer time for handling leak materials, prevent poisonous, hazardous substances polluted source and surrounding environment.
The utility model content
In view of this, the utility model provides a kind of highway to leak two ponds formula accident pool, during burst leakage accident on occurring in highway, can alleviate the diffusion of poisonous and harmful substance, and be used for temporarily storing accident water (liquid), provide buffer time for handling leak materials, prevent poisonous, hazardous substances polluted source and surrounding environment.
Highway of the present utility model leaks two ponds formula accident pool, comprise unhurried current pond and the blow-down pit that is communicated with unhurried current pond lower drain port, described unhurried current pond is communicated in the highway pavement outfall, be set up in parallel the unhurried current chamber that forms by at least one unhurried current barrier partitions along drainage direction in the unhurried current pond, the throttle orifice along drainage direction is set on the described unhurried current baffle plate.
Further, described highway pavement outfall is over against first chamber upper opening that flows slowly along drainage direction;
Further, the throttle orifice on the described unhurried current baffle plate is provided with a row from the bottom to top at least;
Further, the throttle orifice between the adjacent unhurried current baffle plate is along the setting of staggering up and down;
Further, described blow-down pit bottom is provided with the blow-down pit outfall that is communicated in road surface rainwater treatment system, and the blow-down pit outfall is provided with the blow-down pit valve;
Further, described unhurried current pond lower drain port is provided with unhurried current pond valve;
Further, the shared pool wall of described unhurried current pond and blow-down pit, shared pool wall upper end is provided with overfall;
Further, unhurried current baffle plate upper surface is lower than unhurried current pond pool wall.
The beneficial effects of the utility model: highway of the present utility model leaks two ponds formula accident pool, adopt unhurried current pond and blow-down pit structure combining, during burst leakage accident on occurring in highway, accident water flows into the unhurried current pond earlier, because the structure in unhurried current pond causes accident water to flow slowly, and be used for temporarily storing accident water (liquid), for carrying out in-situ processing, the accident treatment personnel gain time, can alleviate the diffusion of poisonous and harmful substance, thereby effectively protect water source and surrounding environment, simultaneously, accident pool also can precipitate rainwater, when heavy rain, rainwater is regulated and stored, reduce the peak flow of draining downstream; The utility model is simple in structure, cheap, be easy to safeguard.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the highway of present embodiment leaks two ponds formula accident pool, comprise unhurried current pond 1 and the blow-down pit 2 that is communicated with unhurried current pond 1 lower drain port 11, described unhurried current pond 1 is communicated in highway pavement outfall 5, be set up in parallel the unhurried current chamber 3 that is separated by at least one unhurried current baffle plate 4 along drainage direction in the unhurried current pond 1, according to the size of unhurried current pond 1 volume, unhurried current chamber 3 quantity can be for a plurality of, and present embodiment adopts the structure in six unhurried current chambeies 3; Throttle orifice 41 along drainage direction is set on the described unhurried current baffle plate 4, and the direction of arrow is drainage direction among the figure; Discharge liquid by throttle orifice 41 substeps, can effectively alleviate the flow velocity of liquid, guarantee buffering effect, prolong efflux time.
In the present embodiment, described highway pavement outfall 5 makes full use of the effect in unhurried current pond over against along first unhurried current chamber upper opening of drainage direction.
In the present embodiment, the throttle orifice 41 on the described unhurried current baffle plate 4 is provided with a row from the bottom to top at least; Size according to unhurried current pond 1 is provided with row's number of throttle orifice 41, and present embodiment is provided with three rows, accident water is moved successively on gradually according to the flow size discharge from throttle orifice from down to up, prevents overflow.
In the present embodiment, the throttle orifice 41 between the adjacent unhurried current baffle plate 4 is along the setting of staggering up and down.
