[0020] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0021] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0022] Embodiment 1: This embodiment provides a dual-purpose urban river system, which has river embankments on both sides of the river. The river bank slope from the top of the embankment to the river channel is provided with green area slopes, revetments and hydrophilic trails in sequence.

[0023] In this case, a dike road is set up on the top of the river bank. Following the principle of river road and park integration, the connection between the dike road on the shore and the municipal roads and community entrances and exits is optimized. It is used as a garden road for leisure and entertainment in daily life. When an emergency occurs, the dike road can provide guarantee for traffic in urban emergency situations.

[0024] In this example, the slope of the green area is set between the revetment and the embankment road. Trees, shrubs, etc. can be planted outside the opening line, and herbaceous plants are mainly used within the opening line.

[0025] In this embodiment, the revetment adopts slope revetment, vertical revetment or compound revetment according to the spatial planning, site status and the premise of meeting flood control safety. The revetment types include ecological gabions, self-embedded retaining wall slope protection, vegetation-type ecological concrete, pine piles, etc.

[0026] In this embodiment, the hydrophilic trail takes into account hydrophilicity and smoothness, and adopts the method of connecting the entire urban river. On the basis of ensuring that flood control meets the standards, the elevation of the hydrophilic trail should take into account the impact of the common flood water level, and it is preferably 20cm-50cm above the normal water level. At the same time, the impact of the common flood water level should be taken into account to reduce the burden of later operation and maintenance. The hydrophilic trail can create a rich and diverse hydrophilic experience space for the public on a daily basis, and serve as a flood channel during the flood season.

[0027] In this case, the embankment road and the hydrophilic trail below are connected through a connecting channel that crosses the slope of the green area. The connecting channel is an important channel connecting the shore and the bottom of the shore. It follows the principle of integration and uses steps, barrier-free ramps or life-saving ladders to achieve convenient connection between the embankment road on the shore and the hydrophilic trail, which serves as an emergency channel for escaping from the river during flood season.

[0028] In this embodiment, the riverbed of the river channel adopts ecological riverbed such as grouted block stones or natural riverbed. Based on the existing conditions of the riverbed and to meet the flood discharge requirements of the entire river channel, the river channel is ecologically improved to enrich the ecological diversity of the river channel, the diversity of water flow patterns, improve the resilience and elasticity of the river channel under extreme climatic conditions, improve the self-purification ability of the river channel, and improve the water quality of the river.

[0029] In this embodiment, a shallow beach connecting the hydrophilic trail is provided in the river channel. The shallow beach is the transition zone between the hydrophilic trail and the ecological riverbed. It is located above the normal water level to meet the daily needs of the public for water enjoyment and planting of aquatic plants.

[0030] In this case, by setting up the main river channel, revetments, slopes, water-friendly trails, dike roads, connecting passages, etc., it is possible to ensure the stability of the riverbed and revetments during floods, as well as emergency escape in emergencies. In daily operations, it is possible to meet people's water-friendly needs and enrich the river service functions.

[0031] Embodiment 2: This embodiment is basically the same in structure as Embodiment 1, except that the revetment in this embodiment is stepped according to the spatial planning and site conditions.

[0032] The following is an example of an urban river system with parks, paths and setbacks:

[0033] The left bank of the river uses retreating steps as revetments and connecting passages to connect the top garden road with the waterfront trail. The right bank uses the park road as the top road, and the revetment adopts vertical concrete retaining walls in combination with flood control and site conditions; the slope greening area adopts grass slope protection.

[0034] This section of the river adopts an ecological riverbed or a natural riverbed to meet safety and ecological requirements. Water-friendly trails are set up on both sides of this section of the river. The water-friendly trails should be 20cm~50cm higher than the normal water level to meet the needs of water-friendliness. Steps down to the river are set up at the bridge head to connect the water-friendly trail under the bank with the municipal roads and bridges on the bank to meet the daily traffic needs of the people along the line; shallows are set up in the ecological riverbed beside the water-friendly trail to meet the needs of daily water-friendliness and planting aquatic plants.

[0035] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
