The urgent flood discharge of a kind of rain flood
The present invention relates to municipal sewage rain flood pipe-line system field, refer to the urgent flood discharge of a kind of rain flood particularly.
For a long time, the many cities of China are all faced with the problems of the rain flood aspects such as flood.First, along with the continuous propelling of city process, city sclerosis area constantly increases, and rainwater infiltration amount constantly reduces, and causes Rainfall runoff to surge.From runoff coefficient, urbanization makes runoff coefficient sharply be increased to 0.8 ~ 0.9 after exploitation from 0.2 ~ 0.3 before exploitation.Meanwhile, the increase of sclerosis area also makes the flow velocity of ground rainwater faster, accelerates the time of rainwater catchment, causes sharply rising in the run-off short time.In addition, the limitation of the many urban rainwater pipelines of China at the design initial stage by development eye, design flow is often on the low side, does not consider large-scale or super-huge precipitation event.
When running into this kind of situation of heavy showers, municipal water treatment systems is limited in one's ability, and a large amount of rainwater converges and can not drain off floodwaters in time, causes sewer pipe cruelly full, forms urban waterlogging, has both caused serious economic loss, and also usually caused casualties.And be limited by current urban architecture, road and underground pipeline system and built up, the underground space is limited, rebuilds or carry out large-scale redevelopment to existing pipe-line system, can cause extreme influence to road along the line and building, also very large investment is needed, so be difficult in a short time realize.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As Fig. 1 ~ 2, the urgent flood discharge of a kind of rain flood, comprise pond 1, overflow wall 3 is provided with in pond 1, pond 1 is divided into the pipe duct 4 of side and the regulating reservoir 5 of opposite side by overflow wall 3, and pipe duct 4 one end is provided with water inlet 6, and the other end is provided with delivery port 7, wherein the caliber of water inlet 6 is greater than the caliber of delivery port 7, and the caliber of delivery port 7 is arranged according to the disposal ability of the Wastewater Treatment Plant be communicated with it.
When rainwater discharge capacity is excessive, delivery port 7 discharges not in time, and current overstock in pipe duct 4, and when current exceed the height of overflow wall 3, current enter in regulating reservoir 5, and current distribute by regulating reservoir 5 further.
In order to increase current by area of passage during overflow wall 3, floating box type weir gate is also provided with in pipe duct 4, floating box type weir gate comprises bearing 15 and two ends and is rotatably connected to the second axis of rotation 14 on pipe duct 4 wall, bearing 15 one end is fixed on the second axis of rotation 14, the other end is connected with door-plate 16, door-plate 16 is provided with buoyancy tank 17, buoyancy tank 17 and bearing 15 are positioned at door-plate 16 homonymy, when the current in regulating reservoir 5 flood buoyancy tank 17, be subject to hydraulic action, buoyancy tank 17 promotes door-plate 16 and rotates around the second axis of rotation 14, the current of door-plate 14 lower end in channel 4 lower than during overflow wall 3 and overflow wall 3 be close to towards the wall of regulating reservoir 5 side.
When current exceed the height of overflow wall 3, floating box type weir gate has certain cumulative effect to current, after buoyancy tank 17 receives buoyancy, upwards overturn, current flow through overflow wall 3 rapidly and enter into regulating reservoir 5, increase floating box type weir gate and effectively increase current by area of passage during overflow wall 3, be conducive to the process of regulating reservoir 5.
Be provided with storage pond 2 below regulating reservoir 5, storage pond 2 is positioned at the below in pond 1, can make full use of limited soil space, makes whole system take less spatial surface.Regulating reservoir 5 sidepiece body of wall offers the first through hole 9 be communicated with between natural water 8, bottom body of wall offers the second through hole 10 be communicated with storage pond 2, bottom body of wall is provided with door-plate 11, is communicated with storage pond 2 by this gate control and regulation pond 5 or is communicated with natural water 8.
Door-plate 11 both side ends is provided with the first axis of rotation 13, first axis of rotation 13 two ends and is rotatably articulated and connected on the wall of regulating reservoir 5 both sides, and door-plate 11 can overturn in a vertical and horizontal direction.The wall of storage pond 2 is provided with oil cylinder 12, the wall of storage pond 2 is provided with cylinder support, oil cylinder 12 end is rotatably articulated and connected with on cylinder support, the piston rod end of oil cylinder 12 is rotatably articulated and connected on door-plate 11, door-plate 11 being driven by piston rod when the first axis of rotation 13 turn to vertical state, covers the first through hole 9, to covering the second through hole 10 during level, realizing the control folding in both direction.
When oil cylinder 12 drives the first axis of rotation 13 to make door-plate 11 turn to level, door-plate 11 lid is sealed and matched with the second through hole 10 and is connected, current now in regulating reservoir 5 flow in natural water 8, when door-plate 11 turn to vertical direction, door-plate 11 and the first through hole 9 are connected, now, the current in regulating reservoir 5 enter in storage pond 2.
Submersible sewage pump 18 is provided with in storage pond 2, submersible sewage pump 18 is positioned at the bottom of storage pond 2, for the effluent discharge of storage pond 2 bottom is carried out advanced treating to Wastewater Treatment Plant, submersible sewage pump 18 is provided with first row waterpipe 20, the bottom that the port of export of first row waterpipe 20 is positioned at pipe duct 4 is communicated with delivery port 7.
Storage pond 2 is also provided with water pump 19, water pump 19 is positioned at the upper strata of storage pond 2, for by the upper strata storm-water drainage of storage pond 2 in natural water 8, water pump 19 is provided with second row waterpipe 21, the port of export of second row waterpipe 21 is communicated with natural water 8, be provided with passage 22 in pond 1, second row waterpipe 21 is communicated with by passage 22 with natural water 8.
During use, rainwater enters in pipe duct 4 from water inlet 6, part water enters into Wastewater Treatment Plant from delivery port 7, when the water yield is excessive, the rainwater that cannot enter into delivery port 7 enters in regulating reservoir 5 by overflow wall 3, sewage in regulating reservoir 5 is disposed to natural water 8 by the first through hole 9 under normal circumstances, and now door-plate 11 covers the second through hole 10.When the waterline of natural water 8 is higher than takeoff line, door-plate 11 turn to vertical direction and covers the first through hole 9, second through hole 10 and open, and the sewage in regulating reservoir 5 enters in storage pond 2, after rainfall stops, by submersible sewage pump 18 and water pump 19, the water in storage pond 2 being emitted.
