Detailed Description

A city compound river channel structure, as shown in figure 1, comprises a river channel upper space 1, a river channel middle space 2 and a river channel lower space 3. And determining the river channel section according to the urban drainage standard and the conventional river channel flow rate. The height of the upper space of the river channel is 1.0-1.5 m, wherein the depth of the landscape water of the river channel is 0.5-1.0 m, and the height of the river channel is 0.5 m. The riverway landscape water is positioned in the riverway upper space, and a sealing isolation layer 8 is arranged between the riverway upper space and the riverway middle space; a rainwater pipe communicated with the outside is arranged in the lower-layer space of the river channel; a pipeline platform 4 for placing a pipeline 9 is arranged between the middle-layer space and the lower-layer space of the river channel; an inlet and outlet 5 for serving the space under the river channel is arranged in the middle space of the river channel. The inlet and outlet are arranged at the outer side of the river channel every 200-300 meters, and are used for the inlet and outlet of personnel and materials for pipeline installation and maintenance. The pipeline interface of the access river course sets up the below at pipeline platform.

In this embodiment, pipeline platforms are disposed on both sides. The width of the platform is determined according to the scale of the pipeline and the maintenance requirement; the height above the platform is determined according to the pipeline hoisting requirement, and is generally not less than 3.0 m; the distance between the platforms at the two sides is not less than the maximum pipe diameter of the pipeline connected to the river channel; the height of the lower part of the platform is determined by calculation according to the daily average rainfall of the city; and a trestle is arranged between the platforms at the two sides every 200-300 meters.

The upper space of the river channel is connected with a front pool of an urban flood drainage pump station at the downstream of the river channel and is provided with a water level control facility, when raining, the water level control facility is opened, and rainwater in the upper space of the river channel is lifted and drained into the urban flood control river channel through the flood drainage pump station; when the rainfall is absent, the water level control facility is closed, and the riverway landscape water is stored in the upper space of the riverway. The middle layer space and the lower layer space of the river channel are directly communicated with a front pool of an urban flood drainage pump station at the lower reaches of the river channel, and during rainfall, rainwater in the middle layer space and the lower layer space of the river channel is lifted and drained into the urban flood control river channel through the pump station. Rainwater in the river channel flows in corresponding space in the rainfall and non-rainfall periods, and the use requirements are met.

The utility model has the following characteristics:

1. the traditional river course in the city is a layer, and the river course is wider, so that a large amount of urban land needs to be occupied. The urban compound riverway is divided into three layers, underground space is fully utilized, the width of the riverway can be greatly reduced, and urban land is greatly saved.

2. The rainfall of the urban year is generally distributed in a specific time period, the rainfall is different in different time periods, and the scale of the urban river is determined according to the short-term and strong rainfall. In the traditional urban river channel, most of the space in the river channel cannot be effectively utilized in the rainless or light-rain time period. The urban compound riverway utilizes the riverway space when the urban compound riverway does not rain, and realizes the efficient utilization of the urban space.

3. Urban pipelines are generally laid in urban roads, the safety of the pipelines is poor, and the roads need to be dug repeatedly when the pipelines are built and replaced. And city compound river course, partial space is used for laying the pipeline, has formed the utility tunnel in city in fact, has made things convenient for the construction of pipeline, has strengthened the safety of pipeline, has reduced "road zip fastener" phenomenon.

4. In the traditional urban riverway, the water level is controlled from top to bottom according to a high water level, a normal water level and a low water level, the normal water level is generally 1.5-2.0 meters away from the ground, the landscape water level is set according to the normal water level of the riverway, and the hydrophilicity of the riverway is poor. The urban compound riverway has the advantages that the landscape water level is arranged on the upper layer of the riverway and is 0.5 m away from the ground, and the hydrophilicity of the riverway is strong.

5. In the traditional urban riverway, the depth of landscape water is generally 1.5-2.0 meters, and in the non-rainy period, rainwater cannot be supplemented in the riverway, so that a large amount of urban reclaimed water is needed for supplementing. The depth of the landscape water in the urban compound riverway is generally 0.5-1.0 m, thus greatly saving the water for the urban reclaimed water.
