Description
Technical field
The invention belongs to underpass technical field of auxiliary facilities, and in particular to a kind of underpass flood reverse-filling row
Water system.
Background technology
In recent years, as urban development, the use of aboveground space are approached to saturation, the underground space is gradually utilized, increasingly
More market place builet below the ground, underground parking, underground storehouse and underground pedestrian walk etc. occur and built extensively in succession, and this is in very great Cheng
Urban land resource scarcity is alleviated on degree, alleviates traffic above-ground pressure.The exploitation of China's underground space is started late, for
Aspect of taking precautions against natural calamities is paid attention to not enough, especially controlling flood.The invasion of underground space flood causes the direct injures and deaths such as equipment loss, casualties,
The indirect injures and deaths such as social communication's interruption can also be caused.It is not clear and definite to the flood control standard of the underground space in current specification and standard
Regulation and requirement, be typically all using earth's surface flood control specification, and spatial surface and underground space structure etc. in the design process
The otherness of aspect, earth's surface flood control specification is set to be not necessarily suitable the underground space.
In original underpass inlet drain scheme such as underground parking design, generally risen in track at slope and set a gradient
For 10-30 degree, it is higher by grade about 80-200mm slope, and sets first to catchment bright ditch in highest point, then again with 10-
30 degree of gradient slope aspect grade, rainwater is directly discharged into Storm Sewer Network in bright ditch, and the bright ditch uses and sets steel or cast iron castor
Son is passed through with sharp vehicle and people, still, because sewerage system is poor, is had once heavy rain to attack when the situation of waterlogging occurs for city
Occur, above-mentioned underpass entrance, which relies solely on the batter drainage method for being higher by grade 80-200mm, to be present substantially 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.

Embodiment
In order to further illustrate the present invention, below in conjunction with the accompanying drawings and the present invention is described in detail embodiment, but not
They can be interpreted as limiting the scope of the present invention.
Embodiment 1
As shown in figs. 1 and 3, whole flood reverse-filling drainage system is vertical with underpass direction, is put down with the length direction of road 20
Row is set；Underpass top surface 18 is preferentially consistent with the gradient of stair 13, underpass entrance ground 1 and outside road 20
Flush, and keep appropriate safe distance, excavate groove 4 and water storage lowland 15 at underpass entrance ground 1, outside groove 4
Portion sets foot-operated protective cover 2 and vertical supporting 3, the equidistantly distributed of vertical supporting 3, and the sectional dimension of water storage lowland 15 is protected with foot-operated
The sectional dimension of shield 2 is consistent, and the height of water storage lowland 15 and walkway 14 are highly consistent, and water storage lowland 15 and groove 4
Opening is corresponding to be connected, and the inwall of groove 4 and water storage lowland 15 smear waterproof layer 5, and the bottom of groove 4 sets the branch for being fixed on bottom surface
Strut 10, support bar 10 are hinged and connected with being arranged on the reverse-filling water-stop sheet 9 of the opening of groove 4, permeable protection cap 6 and reverse-filling
Water-stop sheet 9 is connected with connecting line 11, reaches the effect of two level flood reverse-filling.
Embodiment 2
As in Figure 3-5, groove 4 is excavated on underpass entrance ground 1, the outside of groove 4 sets foot-operated protective cover 2 and vertical branch
Support 3, the inwall of groove 4 smear waterproof layer 5, and the bottom of groove 4 sets support bar 10, and support bar 10 is with being arranged on the opening of groove 4
Reverse-filling water-stop sheet 9 is connected, and permeable protection cap 6 is connected with reverse-filling water-stop sheet 9 with connecting line 11, so as to reach flood reverse-filling
Effect.
Embodiment 3
As seen in figs, two level flood backward flowing preventing device top is provided with permeable protection cap 6, and the permeable specification of protection cap 6 is than groove 4
The slightly wide 1-2cm of specification, bottom are provided with dmp filter layer 7, and side wall is rigid sidewalls water fender 8, two level flood backward flowing preventing device bottom
There is certain space in portion with the bottom of groove 4, is connected with sewer water inlet 12, sewer water inlet 12 has certain slope, is easy to rain
Water smoothly imports blowdown vertical shaft 16 along sewer water inlet 12, is excluded from sewer branch road 17, the duct orientation of sewer branch road 17
It is consistent with road direction of traffic, one-level backward flowing preventing device 19 is set in blowdown vertical shaft 16, and one-level backward flowing preventing device 19 still sets anti-
Pour in down a chimney water-stop sheet 9 and connecting line 11, thin portion structural principle is identical with the two level backward flowing preventing device in groove 4, and one-level is anti-down filling
19 are put as the first line of defence for preventing the counter-current of sewage of sewer branch road 17.
Embodiment 4
As shown in Figures 4 and 5, rainwater enters drainage system from permeable protection cap 6, one-level backward flowing preventing device 19, plays a role first
Ensure normal drainage works, cause one-level backward flowing preventing device 19 to fail if current are excessive, water level persistently rises, with groove 4
Interior water level rises, and two level flood backward flowing preventing device is risen simultaneously using buoyancy, and the connecting line 11 in permeable protection cap 6 drives anti-down
Fill water-stop sheet 9 gradually to close, prevent that water level is too high in sewer 12, pour in down a chimney phenomenon more than inlet of sewer ground 1；This
When side wall water fender 8 risen simultaneously with two level flood backward flowing preventing device, unnecessary precipitation is trapped among in water storage lowland 15, played in short-term
Dash flood act on, pedestrian can walkway 14 by, outside road 20 is normally open to traffic, and is not interrupted using sexual function,
Treat that water level gradually reduces in sewer 12, two level flood backward flowing preventing device is slowly dropped in groove 4, and reverse-filling water-stop sheet 9 is beaten
Open, current normal discharge again.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
