Description

A sponge rural ecological landscape drainage ditch structure

Technical Field

The utility model belongs to the technical field of landscape drainage facilities, and in particular relates to a sponge rural ecological landscape drainage ditch structure.

Background technique

Rural development and construction have destroyed the natural sponge body, resulting in flooding every time it rains and drought after rain, and at the same time causing a series of problems such as water pollution, water resource shortage, lack of water safety, and disappearance of water culture; Sponge villages refer to villages that can adapt to environmental changes and respond to natural disasters like sponges, absorbing water, storing water, infiltrating water, and purifying water when it rains, and releasing and utilizing the stored water when needed; during the construction of existing projects, drainage ditches will be built in low-lying areas prone to water accumulation, so that the water collected in low-lying areas near the roadbed, crops, and houses is led into the ditch, thereby ensuring the normal use of the road. However, the appearance of traditional drainage ditches is relatively rigid, the design structure is simple, the ecological effect is relatively lacking, and the collected rainwater is usually directly discharged into the rainwater and sewage pipe network, which is not beneficial to the ecological environment.

In order to solve the above problems, the existing Chinese utility model patent with application number 201920904017.8 discloses a sponge city concept ecological landscape drainage ditch structure, which is different from the traditional drainage ditch and is a ground drainage channel that adopts plant measures or plant measures combined with engineering measures. The drainage ditch structure is provided with a concrete pool wall, a planting box is laid on the concrete pool wall, a ceramsite filter layer is provided on the lower layer of the planting box, and green plants are provided on the upper layer of the planting box, which not only filters and purifies the water source but also improves the ornamental value.

However, the planting boxes of this drainage ditch structure are directly laid in the concrete pool wall. After the rainwater flows into the planting boxes, it needs to be filtered through the lower expanded clay filter layer before it can be discharged. When the rainfall is heavy, the water seepage function of the expanded clay filter layer in the planting boxes is weak and cannot filter out the rainwater in time. The excess rainwater will spread and remain on the ground.

The bottom of the concrete layer 1 is a gravel cushion layer 6, and the bottom of the gravel cushion layer 6 is a plain soil ramming layer 7. A drainage pipe 8 is connected between the trough 2 and the gravel cushion layer 6. Rainwater flows into the planting box 3, passes through the planting soil layer 5 and the ceramsite filter layer 4, and is discharged to the gravel cushion layer 6 at the bottom through the drainage pipe 8.

The concrete layer 1 is provided with a cavity 9 on both sides of the pit 2, an opening 10 is provided between the cavity 9 and the pit 2, a drainage pipe 8 is connected between the bottom of the cavity 9 and the gravel cushion layer 6, a ceramsite filter layer 4 is provided at the lower layer of the cavity 9, a counterweight 11 is provided in the cavity 9, the weight of the counterweight 11 is greater than the weight of the planting box 3 after planting green plants, and the weight of the counterweight 11 is less than the weight of the planting box 3 after being soaked in rainwater, a traction rope 12 is connected to the counterweight 11, and the traction rope 12 is connected to the lower part of the side wall of the planting box 3 after being guided by the opening 10. Under the traction of the counterweight 11, the planting box 3 is suspended and covers the opening 10, and the top surface of the seed box is flush with the top surface of the concrete layer 1.

The sum of the distance from the bottom edge of the opening 10 to the top surface of the concrete layer 1 and the height of the planting box 3 is equal to the depth of the groove 2. When the rainfall is too heavy, the planting box 3 does not have time to penetrate the rainwater, and the rainwater will be retained in the planting box 3. When there is too much rainwater in the planting box 3, the weight of the end of the planting box 3 is greater than the weight of the counterweight 11, and the planting box 3 drops. When the bottom of the planting box 3 contacts the groove 2, the top of the planting box 3 is located below the opening 10 to ensure that the opening 10 is exposed. After the opening 10 is exposed, the rainwater flows into the cavity 9 through the opening 10, and is filtered through the expanded clay filter layer 4 in the cavity 9 and then discharged, thereby improving the filtering effect of rainwater and avoiding waterlogging on the road.

Specifically, a mesh frame 13 is provided at the top of the drain pipe 8 , and the mesh frame 13 can support the expanded clay filter layer 4 to prevent the expanded clay filter layer 4 from being blocked in the drain pipe 8 .

Specifically, a support column 14 is provided in the cavity 9 , and the support column 14 can play a supporting role to prevent the cavity 9 from collapsing.

Specifically, the bottom edge of the opening 10 is in an arc shape, the arc edge and the traction rope 12 have a larger force-bearing area, and there are no sharp edges, which can prevent the traction rope 12 from being scratched or broken.

Specifically, a folded edge is provided on the top of the side wall of the planting box 3, and the folded edge is slidably connected to the groove pit 2. An arc groove 15 matching the traction rope 12 is provided at the bottom of the folded edge. When the bottom of the planting box 3 contacts the groove pit 2, the traction rope 12 can be located in the arc groove 15 to avoid a gap between the folded edge and the opening 10. A rubber layer can also be provided at the bottom of the folded edge to improve the sealing effect.

The method of using the utility model is as follows: after planting green plants in the planting box 3, place it in the groove pit 2. Under the action of the counterweight block 11, the planting box 3 is suspended and the opening 10 is covered. When it rains, rainwater flows into the planting box 3 and is filtered by the planting soil layer 5 and the expanded clay filter layer 4. It is then discharged to the gravel cushion layer 6 at the bottom through the drain pipe 8, thereby achieving a filtering effect. When there is too much rainwater, the rainwater will be retained in the planting box 3. After the weight at one end of the planting box 3 is greater than the weight of the counterweight block 11, the planting box 3 descends, exposing the opening 10, and the rainwater flows into the cavity 9 through the opening 10. It is filtered by the expanded clay filter layer 4 in the cavity 9 and then discharged, thereby improving the filtering effect of the drainage ditch structure and avoiding the occurrence of waterlogging on the road.
