Description
Technical Field
The invention belongs to the technical field of rainwater treatment and reuse, and particularly relates to a viaduct rainwater utilization system.
Background
The viaduct bridges in cities are more and more, and the length of the viaduct bridges is longer and longer. On an elevated bridge floor, due to tire wear, tail gas pollution, dry and wet settlement of atmospheric air and the like, a large amount of pollutants are gathered on the surface of an elevated road, the pollutants are washed by rainwater to form bridge floor runoff, the bridge floor runoff is discharged into an urban river water system through a downspout and a collecting well without treatment through a rainwater pipe network, and the initial rainwater runoff carrying a large amount of pollutants brings serious pressure to the ecology of the urban water system. On the other hand, most of the elevated roads are shrub greenbelts, and because natural rainfall cannot be accepted, greening maintenance basically depends on manual irrigation of tap water, and high-frequency irrigation not only consumes a large amount of tap water resources, but also easily causes sudden hardening and is not beneficial to plant growth.

Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1, the rainwater collecting device comprises a rainwater collecting unit 1 and a rainwater storage unit 3, wherein the lower part of the rainwater collecting unit 1 is connected with a sewage intercepting hanging basket 2, the lower layer of the sewage intercepting hanging basket 2 is a pebble area 23, the bottom of the sewage intercepting hanging basket 2 is provided with a water outlet 22, the upper side wall of the sewage intercepting hanging basket is provided with an overflow port 21, and the water outlet 22 and the overflow port 21 are combined together by a water delivery pipe 24 to be communicated with the rainwater storage unit 3;
the rainwater storage unit 3 is arranged at the middle lower part of the bridge pier; the top of the rainwater storage unit 3 is provided with an overflow pipe 31, the middle part is embedded with a filling frame 33, and the bottom is provided with an emptying valve 34; the spraying pipe 32 penetrates through the side wall of the upper part of the rainwater storage unit 3, the spraying pipe 32 is a siphon elbow, a pipeline on one side of a water inlet of the spraying pipe penetrates through the filling frame 33 and is inserted into a cavity of the lower part of the rainwater storage unit 3, and a valve 36 and a spray head 35 are arranged on a pipeline on one side of a water outlet of the spraying pipe; the overflow pipe 31 is connected with the buried perforated pipe 4, and the rotating handle 37 arranged on the outer wall of the rainwater storage unit 3 is connected with the middle shaft of the filling material frame 33.
The rainwater collection unit 1 is a rainwater port and is arranged at the road expansion joint; the filling frame 33 adopts vermiculite as the filling material, and the vermiculite has the characteristics of loose soil, good air permeability, strong water absorption, small temperature change and the like.
The using process of the invention is as follows:
when raining, the emptying valve 34 and the valve 36 are closed, and rainwater generated by the viaduct flows into the rainwater collection unit 1 and the sewage interception hanging basket 2 through the road expansion joint. The rainwater entering the sewage intercepting hanging basket 2 is filtered by the pebble zone 23 and then flows into the rainwater storage unit 3 through the water outlet 22 and the water delivery pipe 24. Along with the increase of rainfall intensity and rainfall duration, the runoff flow discharged into the sewage interception hanging basket 2 exceeds the filtering flow of the pebble area 23, and untreated rainwater flows into the rainwater water storage unit 3 through the overflow port 21 and the water conveying pipe 24 of the sewage interception hanging basket 2. The rainwater drained into the rainwater storage unit 3 is further filtered by the filler frame 33 and then stored in the lower cavity of the rainwater storage unit 3. When more rainwater is drained into the rainwater storage unit 3, the rainwater which is not filtered by the filler frame 33 is accumulated in the upper cavity of the rainwater storage unit 3 and is connected with the buried perforated pipe 4 through the overflow pipe 31 to irrigate the trees in the green belt.
In the interval period of rainfall, when trees in the green belt need to be watered, the emptying valve 34 is closed, the valve 36 is opened, and the rainwater stored in the cavity at the lower part of the rainwater storage unit 3 is sprayed onto the plants under the viaduct through the spraying pipe 32 and the spray head 35 by utilizing the siphon action. After the rainwater in the lower cavity of the rainwater storage unit 3 is gradually drained, the rainwater accumulated in the upper cavity of the rainwater storage unit 3 is further filtered by the filler frame 33, and the filtered rainwater is sprayed onto the plants under the viaduct through the spraying pipe 32 and the spray head 35. When the rainwater in the rainwater storage unit 3 is not enough to be discharged by the siphon action, the emptying valve 34 is opened to discharge part of the rainwater remained in the lower cavity of the rainwater storage unit 3.
During later maintenance, the emptying valve 34 is opened, the valve 36 is closed, the rotating handle 37 is used for rotating the packing frame 33, pollutants accumulated on the packing frame 33 fall off from the packing frame 33 due to the action of gravity, and therefore the purpose of cleaning the packing frame 33 is achieved.
