Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, in the present embodiment, the revetment structure of only one side bank slope is taken as an example:
the invention relates to a sponge type bank protection structure for two banks of a harbor canal water system, which comprises: two water storage ecological embankments 1 arranged on two banks of the harbor canal water system;
each water storage ecological embankment 1 is arranged inside a corresponding bank slope along the length direction of the water system;
the interior of each water storage ecological embankment 1 is of a hollow structure, one side, close to a water system, of each water storage ecological embankment 1 is provided with an openable and closable opening structure, and the opening structures are communicated with the water system;
and a collecting device capable of collecting and filtering rainwater is arranged on one side of each water storage ecological embankment 1, which is far away from the water system.
The ecological water storage embankment arranged in the bank slopes on the two banks is hollow, and has a water storage function. And the opening structure of the ecological water storage embankment can be opened and closed, so that the invention ensures that surplus rainwater is effectively collected and stored, and when the upper limit of the water storage capacity of the water storage embankment at the edge of the harbor lake is reached, the surplus rainwater is discharged into the harbor lake through the pipeline, thereby effectively preventing the phenomena of water accumulation, water logging and the like generated after the water storage embankment is saturated, and further reducing the negative influence caused by the water accumulation and the water logging. In addition, a collecting device capable of collecting and filtering rainwater is arranged on one side, away from the water system, of each water storage ecological bank, so that rainwater entering the water storage ecological banks is filtered in advance.
Further, the opening structure comprises a third communication duct 12 and a corresponding check valve 9;
one end of each third communication pipeline 12 is communicated with the interior of the water storage ecological embankment 1, and the other end of each third communication pipeline is communicated with a water system;
the check valve 9 is provided on the other end of the third communication pipe 12.
The check valve 9 functions to open and close the opening structure. When the water system is in a flood season, the check valve 9 is closed, so that water in the water system cannot flow backwards into the revetment structure; when the water system is in drought, the check valve 9 can be opened, so that rainwater stored in the revetment structure flows into the water system.
Still further, the collecting device comprises: an overflow well system for collecting rainwater, said overflow well system being made up of a plurality of overflow wells 6;
each overflow well 6 is arranged in a sunken green land 7 near the bank slope;
the overflow well 6 is of a top opening structure;
the overflow well 6 is communicated with the interior of the water storage ecological embankment 1.
Still further, the collecting device further comprises: the water storage well system is used for filtering rainwater and consists of a plurality of water storage wells 5 which are communicated with each other;
the water storage well system and the water storage ecological embankment 1 are arranged in parallel inside the corresponding bank slope;
each water storage well 5 is communicated with the corresponding water storage ecological embankment 1.
As can be seen from fig. 2, in the water storage well system, not every water storage well 5 is connected with an overflow well 6. Since the overflow well 6 is provided according to the sunken green land 7 for collecting rainwater collected in the sunken green land 7.
Of course, only the overflow well system or the water storage well system is arranged in the collecting device, so that the function of collecting rainwater can be realized.
Furthermore, the water storage well system is positioned between the corresponding water storage ecological embankment 1 and the overflow well 6;
one side of the water storage well system is communicated with each corresponding overflow well 6, and the other side of the water storage well system is communicated with the corresponding water storage ecological embankment 1.
When the collecting device comprises both an overflow well system and a water storage well system, the overflow well system is more effective in collecting rainwater, and the water storage well system is more effective in filtering rainwater. Although both the overflow well system and the water storage well system have the function of collecting and filtering rainwater.
Still further, each water storage well 5 is communicated with the corresponding water storage ecological embankment 1 through a first communication pipeline 2;
each overflow well 6 is communicated with the corresponding water storage well 5 through a second communication pipeline 11, so that the communication with the water storage well system is realized.
Preferably, in the water storage well 5 communicating with the overflow well 6:
the elevation of the second communication pipeline 11 at the outlet of the water storage well 5 is higher than the elevation of the corresponding first communication pipeline 2 at the inlet of the water storage well 5;
a partition wall 3 is vertically inserted at the bottom of the water storage well 5;
the two surfaces of the partition wall 3 respectively face the second communicating pipeline 11 at the outlet of the water storage well 5 and the first communicating pipeline 2 at the inlet of the water storage well 5;
the height of the partition wall 3 is lower than that of the water storage well 5, and the length of the partition wall 3 is the same as that of the water storage well 5.
In the storage well 5 communicating with the overflow well 6, the partition wall 3 is provided to further filter the rainwater flowing from the overflow well 6 into the storage well 5. As shown in fig. 1, the bottom of the overflow well 6 is generally at a higher elevation than the bottom of the storage well 5. Rainwater collected by the overflow well 6 can flow into the water storage well 5 through the second communication pipe 11. The second communicating pipe 11 is arranged higher at the outlet of the water storage well 5 than at the inlet of the first communicating pipe 2 at the water storage well 5, and then the partition wall 3 is vertically inserted between the outlet and the inlet, so that the rainwater flowing out of the outlet can be settled for a period of time. Thus, due to the action of the partition wall 3, the rainwater flowing out of the outlet is slowly precipitated, and sediments (such as silt) in the rainwater are deposited at the bottom of the water storage well 5 and are blocked by the partition wall 3. When the water flows into the water storage well 5 from the outlet and slowly increases and submerges the partition wall 3, the settled rainwater flows into the corresponding water storage ecological embankment 1 through the first communication pipeline 2.
Preferably, a water purifying device 4 is arranged at the top opening of each overflow well 6; so that rainwater entering the overflow well 6 can be filtered by the water purification device 4 in advance.
The top of each water storage well 5 is communicated with the bank slope ground, and a water purifying device 4 is arranged at the top of each water storage well 5; it is understood that the water storage well 5 not communicating with the overflow well 6 has a rainwater collecting ability.
And a water permeable structure 8 is arranged on the land slope ground, and the water permeable structure 8 covers the top of the water storage ecological embankment 1 and the top of each water storage well 5 and extends to the surface of the sunken green land 7 near the land slope.
Because the permeable structure 8 extends to the surface of the sunken green land 7 near the bank slope, water can be accumulated in the sunken green land 7 and passes through the permeable structure 8 and the preliminary filtration of soil in advance.
In the technical scheme, each water storage ecological embankment 1 is divided into a plurality of water storage ecological embankment units along the length direction;
each water storage ecological embankment unit is correspondingly communicated with at least one water storage well 5.
As shown in fig. 2, the ecological water storage embankment 1 is divided into a plurality of ecological water storage embankment units by the partition boards 14. Therefore, the independence of the water storage cabins in the water storage ecological embankment 1 can be ensured, and the water storage performance of each water storage ecological embankment unit is not influenced mutually.
As shown in fig. 1, a small bioretention strip assembly 10 is provided at the outlet of the open structure. The small bioretention belt assembly 10 also has a rainwater purification effect, which forms the last purification step of rainwater into a water system.
As shown in fig. 2, a plurality of top through holes 13 are formed at the top of the water storage ecological bank 1, so that the water storage ecological bank 1 itself has a function of collecting rainwater. Because the top of the water storage ecological embankment 1 is covered with the permeable structure 8, the rainwater directly entering the water storage ecological embankment 1 is primarily filtered.
In the invention, the water storage ecological embankment 1, the water storage well 5 and the overflow well 6 are all made of reinforced concrete structures.
The working process of the embodiment is as follows:
1. the rainwater passes through the permeable structure 8 and the sunken greenbelt (rainwater garden) 7, is biologically retained for first purification, and the water flow direction is controlled by utilizing the downward gradient of the permeable layer, so that the rainwater flows into the overflow well 6 in the sunken greenbelt 7;
2. the water purifying device 4 on the overflow well 6 carries out secondary purification on the rainwater flowing into the overflow well 6; meanwhile, the water purifying device 4 on the water storage well 5 also purifies the rainwater directly entering the water storage well 5;
3. rainwater after secondary purification enters the water storage well 5 through the second communicating pipeline 11, and the partition wall 3 for the water storage well is separated, so that mud and sand in the rainwater can be precipitated, and the water storage effect can be achieved, so that the rainwater flows into the water storage well 5 for third purification;
4. rainwater purified for the third time enters the water storage ecological embankment 1 through the first communication pipeline 2, the water storage ecological embankment 1 is of a reinforced concrete structure, water is stored under the condition that the flood fighting capacity is guaranteed, and the space of a large embankment is effectively utilized;
5. after rainwater in a certain water storage ecological embankment unit is saturated, the rainwater is drained from the harbor channel lake through a third communication pipeline 12, a check valve 9 is arranged on the third communication pipeline 12 to prevent rainwater from flowing backwards due to rising of a water surface in a flood season, and meanwhile, a small biological retention belt assembly 10 is arranged at a position, close to the lake, of the third communication pipeline 12 to filter the rainwater.
According to the invention, the sponge is implanted into the flood control system, the water storage embankment is arranged along the whole line of the harbor canal lake, and the water-proof retaining wall is arranged at a proper distance, so that the independence of the water storage cabins is ensured. The large water storage dike really plays a role in regulation and storage, namely rainwater around the flood season firstly enters the water storage pool for storage, and then enters the harbor channel lake after saturation, so that the water flow pressure of the harbor channel lake caused by sudden increase of the rainfall is reduced, and meanwhile, the rainwater in the water storage cabin is pumped out for irrigation in dry seasons.
The invention can play a role in rapid seepage and rapid flow for rainfall, ensures that surplus rainwater is effectively collected and stored, and can effectively prevent the phenomena of water accumulation, waterlogging and the like generated after the water storage embankment is saturated after the surplus rainwater is discharged into the harbour channel lake through the pipeline after the water storage capacity of the water storage embankment at the harbour channel lake is reached, thereby reducing the negative influence caused by the water accumulation and the waterlogging. The invention combines the sponge idea with harbour canal lake water area management, has the advantages of ecological environmental protection, rainwater purification and utilization, good flood control effect and the like, and is worthy of popularization and application.
With the rise of the sponge concept, the ecological embankment technology and the rainwater purification and recycling are carried forward at the same time, so that the flood control effect is achieved, and the sponge concepts of seepage, stagnation, storage, purification, use and drainage can be realized. The invention combines the sponge city construction idea with the harbor canal lake protection dike, can contain a part of water body to reduce the water surface elevation in the flood season, and can store and utilize the collected rainwater in dry seasons. In the rainwater infiltration and collection process, a water permeable structure 8, a sunken greenbelt 7 and a water purifying device 4 are adopted; the water storage well 5 and the biological detention zone 10 are used for multi-stage purification to ensure the water quality. Compared with the traditional revetment embankment body form, the structure is buried in the embankment body to improve the overall stability and the anti-overturning capacity.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
