It for 10-30 degree, is higher by the slope of grade about 80-200mm, and catchments bright ditch in highest point setting first, then again with 10-
30 degree of gradient slope aspect grade, rainwater is directly discharged into Storm Sewer Network in bright ditch, which uses and set steel or cast iron castor
Son is passed through with sharp vehicle and people, and still, since sewerage system is poor, once heavy rain, to attack city, there is a situation where have during waterlogging
Occur, above-mentioned underpass entrance, which relies solely on the batter drainage method for being higher by grade 80-200mm, to be existed significantly not
Foot, especially severe is it occur frequently that some basements are steeped in rainwater, huge property loss may be brought to the people, even
Appearance allows the situation that above ground structure and life are in danger, so providing a kind of effective underpass waterproof system ten
Divide necessary and important.

Specific embodiment：
In order to further illustrate the utility model, the utility model is retouched in detail with reference to the accompanying drawings and embodiments
It states, but they cannot be interpreted as to the restriction to scope of protection of the utility model.
Embodiment 1
As shown in figs. 1 and 3, entire flood reverse-filling drainage system is vertical with underpass direction, with 20 length side of road
To being arranged in parallel；Underpass top surface 18 is preferentially consistent with 13 gradient of stair, underpass entrance ground 1 and external horse
Road 20 flushes, and keeps appropriate safe distance, and groove 4 and water storage lowland 15, groove are excavated at underpass entrance ground 1
The foot-operated protective cover 2 of 4 outside settings and vertical supporting 3,3 equidistantly distributed of vertical supporting, the sectional dimension and foot of water storage lowland 15
The sectional dimension for stepping on protective cover 2 is consistent, and the height of water storage lowland 15 and walkway 14 are highly consistent, and water storage lowland 15 with it is recessed
4 opening of slot is correspondingly connected with, and 4 inner wall of groove and water storage lowland 15 smear waterproof layer 5, and bottom surface is fixed in the setting of 4 bottom of groove
Supporting rod 10, supporting rod 10 is hinged and connected with being arranged on the reverse-filling water-stop sheet 9 of 4 opening of groove, permeable protection cap 6 with it is anti-
Pour in down a chimney water-stop sheet 9 to be connected with connecting line 11, reach the effect of two level flood reverse-filling.
Embodiment 2
As in Figure 3-5, in the excavation groove 4 of underpass entrance ground 1,4 outside setting of groove is ridden protective cover 2 and is erected
To support 3,4 inner wall of groove smears waterproof layer 5,4 bottom of groove setting supporting rod 10, and supporting rod 10 is open with being arranged on groove 4
The reverse-filling water-stop sheet 9 at place is connected, and permeable protection cap 6 is connect with the connecting line 11 of reverse-filling water-stop sheet 9, is prevented so as to reach flood
Pour in down a chimney effect.
Embodiment 3
As seen in figs, two level flood backward flowing preventing device top is equipped with permeable protection cap 6, permeable 6 specification ratio of protection cap
The slightly wide 1-2cm of 4 specification of groove, lower part are equipped with dmp filter layer 7, and side wall is rigid sidewalls water fender 8, and two level flood is anti-down filling
There is certain space in bottom set portion with 4 bottom of groove, is connected with sewer water inlet 12, sewer water inlet 12 has certain slope, just
Blowdown vertical shaft 16 is smoothly imported along sewer water inlet 12 in rainwater, is excluded from sewer branch 17,17 pipeline of sewer branch
Direction is consistent with road direction of traffic, and setting level-one backward flowing preventing device 19 in blowdown vertical shaft 16, level-one backward flowing preventing device 19 is still set
Reverse-filling water-stop sheet 9 and connecting line 11 are put, thin portion structural principle is identical with the two level backward flowing preventing device in groove 4, and level-one is anti-down
Filling device 19 is as the first line of defence for preventing 17 counter-current of sewage of sewer branch.
Embodiment 4
As shown in Figures 4 and 5, rainwater enters drainage system from permeable protection cap 6, and level-one backward flowing preventing device 19 plays first
Effect ensures normal drainage works, level-one backward flowing preventing device 19 is caused to fail if flow is excessive, water level persistently rises, with recessed
Water level rises in slot 4, and two level flood backward flowing preventing device is risen simultaneously using buoyancy, and the connecting line 11 in permeable protection cap 6 drives
Reverse-filling water-stop sheet 9 is gradually closed, and prevents water level in sewer 12 excessively high, is poured in down a chimney more than inlet of sewer ground 1 existing
As；Side wall water fender 8 rises simultaneously with two level flood backward flowing preventing device at this time, and extra precipitation is trapped among in water storage lowland 15, rises
It is acted on to water blocking flood in short-term, pedestrian can pass through in walkway 14, and external road 20 is normally open to traffic, and is not occurred using sexual function
Interruption, treats that water level continuously decreases in sewer 12, two level flood backward flowing preventing device is slowly dropped in groove 4, reverse-filling water proof
Plate 9 is opened, flow normal discharge again.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
