In the isosceles trapezoid shape of big mouth upward.
The utility model has following advantageous effect：
1st, deck runoff central drainage is set in the river that the utility model can be limited in wellhead protection zone in landform
It applies concentrated water to collect, and what can be stablized is present in river and separates rainwash and deck runoff, keeps away
Exempt from deck runoff to pollute water head site.
2nd, can will be collected on bridge floor by being located at the adsorption cleaning layer of emergency lagoon bottom and concentrated on should for the utility model
Pollutant absorption and a degree of purified treatment in anxious pond, facilitate the later stage to focus on.
3rd, the utility model reduces the collection difficulty of bridge floor central drainage while water head site is protected, and has saved design
Construction cost has saved highway land, facilitates later stage centralized processing.

Specific embodiment
The utility model is made further instructions below in conjunction with attached drawing.
As shown in Figure 1, the utility model offer is a kind of suitable for collecting answering for deck runoff in wellhead protection zone
Anxious pond, the emergency lagoon outermost are bricklaying barricade 1, and effect is to keep apart emergency lagoon and external water head site runoff, and energy
Ensure that emergency lagoon can be stabilized in river；Layer 9 is filled in the inside of bricklaying barricade 1 for gravelly soil, mainly plays filling and makees
With；Gravelly soil fills the inside of layer 9 as Base with Sand Gravel Cushion 8, and main function is levelling before casting concrete to prevent damage antiseepage
Film 7；8 inside of Base with Sand Gravel Cushion is antiseepage film 7, and antiseepage film 7 uses 18 antiseepage films, and it acts as the pollutants prevented in emergency lagoon
It leaks；The inside making of antiseepage film 7 be 30cm cast-in-place concrete layer 6, main function be to be formed one have it is strong
Degree and the volume of certain leakproofness are used for accommodating pollutant；Someone's row is set in cast-in-place concrete layer 6 to mark time 2, it is convenient manually into
Enter to clear up emergency lagoon and replace pollutant adsorption cleaning layer 5；The pollutant absorption that emergency lagoon bottom is covered with 40cm thickness is net
Change layer 5, be 1 by volume ratio:1:It is laid with, pollutant can be adsorbed after 1 blue or green sand, more suction enclosure materials and sawdust mixing
And a degree of purification, later stage people is facilitated to focus on altogether；The outside of bricklaying barricade 1, mark time 2 position of face people's row are equipped with people
Row ladder 4, facilitates worker to enter, by prefabricated in bricklaying barricade 1Reinforcing bar is formed；1 upper end of bricklaying barricade, equipped with one circle every
From fence 3, be made of electrowelding net and segregator barriers diagonal brace 11, mainly prevent non-working person climb up bricklaying barricade 1 fall by mistake should
It has an accident in anxious pond, the position of circle 3 face people's row ladder 4 of segregator barriers facilitates worker to enter equipped with segregator barriers door 10.
The utility model is carried out explained further below：
The utility model is typically placed under bridge, and the selection of position can be avoided according to the selection of orographic condition adaptation to local conditions
Apart from bridge too far；If the shape of similary emergency lagoon can be also changed according to size and landform is remembered, to avoid favourable opposition is crossed
Brush is advisable.
Its volume can collect area according to local rainfall and bridge floor central drainage and carry out calculating selection, be held with design discharge
Design volume of the rainfall volume of continuous rainfall 20min as emergency lagoon, the calculation formula of the design discharge of deck runoff are：
Q=ψ Fq
In formula：ψ-runoff coefficient (asphaltic road-mix surface course takes 0.9)
F-catchment area (hm2)
Q-storm intensity, for the storm intensity (L/ (shm of time of concentration2))
The calculation formula of storm intensity can refer to following formula and be calculated：
In formula：P-repetition period of rainfall；
T-rainfall duration.
The volume of the utility model should meet the following conditions：
1st, hazardous materials transportation vehicle of the traveling on bridge all leaks the dangerous material loaded in accident, and passes through
Bridge floor central drainage facility is discharged into emergency lagoon, and the volume of dangerous material is about 5m3。
2nd, occur to undergo rainstorm weather while accident, rainwater is imported in emergency lagoon simultaneously.
By conditions above as it can be seen that while the least favorable condition during emergency lagoon use in the utility model is heavy rain
It loads HAZMAT vehicle and accident occurs, therefore its volume should be greater than the rainwater for being continued rainfall 20min with local heavy rain rainfall and being collected
Volume and pollutant volume and.
During the use of the utility model, pollutant adsorption cleaning layer 5 should be regularly replaced, leakage accident is not occurring
In the case of replace once within every 6 months, and must be cleared up and be replaced in time after accident every time.
