Problems solved by technology

[0004] (1) The constant water level of the current ecological river type needs to ensure a certain water level to meet the ecological requirements. When heavy rainfall and typhoons come, this constant water level will cause insufficient drainage capacity of the river.
When the water level of the river channel is too high due to the lack of flexible adjustment properties, it will put pressure on the municipal pipe network and cause many problems such as urban waterlogging
[0005] (2) In the heavy rainfall typhoon area, after a heavy rainfall and drainage, the ecological construction measures in the current ecological river type need to be re-arranged, resulting in a waste of resources
[0006] (3) The current ecological river channel type only relies on the height difference between the upstream and downstream water heads to control the drainage efficiency, and the drainage guarantee capacity is insufficient
[0007] (4) After the current ecological river channel type is drained by heavy rainfall, the water flow slows down and sedimentation occurs
Bottom mud cleaning requires manual dredging to lower the water level of the river during the non-flood season. During the non-rainfall season, the river water will be polluted twice due to the river bottom silt, which is not conducive to the continuous development of the ecological capacity of the river.
[0008] (5) For the reconstruction of rivers in urban construction areas, the range of the blue line of the original rivers is relatively narrow, and the current type of rivers is not conducive to the construction of narrow river lands, so it is not conducive to the comprehensive functions of river drainage, ecological functions and landscape functions reflect

Embodiment Construction

[0023] The present invention will be described below in conjunction with the accompanying drawings.

[0024] The present invention is composed of a river bank slope 1, a guide wall 2 for a river channel functional zone, a bottom slope capsule 3, a water filling port 4 and a water discharge port 5. The cross-section of the river course is divided into three areas: flow area I, ecological landscape area II, and bottom slope capsule water-filled area III. The bank slope 1 of the river course is made up of soil and stones; the guide wall 2 of the functional division of the river course is formed by pouring concrete; the capsule body 3 of the bottom slope is made of rubber, and the capsule body is hollow and can be filled with water to make it expand. In the non-drainage period, the water-filled zone III of the bottom slope capsule is full of water, and the bottom slope is relatively slow; the water flow in the flow zone I area is slow; the ecological landscape zone II area is comp...

Abstract

The invention relates to an ecological artificial channel with a variable water-crossing section. The ecological artificial channel comprises a channel body, a bottom slope and a channel bank slope and is characterized in that channel function division guide walls are arranged on the two sides of the channel body, a bottom slope bag is placed on the bottom slope, a water charging opening and a dewatering opening are formed in the bottom slope bag, and ecological landscape partitions are arranged on the channel bank slope.

Description

technical field [0001] The invention relates to an ecological artificial river channel with variable cross section. Background technique [0002] At present, the construction of ecological river courses is generally carried out from two aspects: on the one hand, the construction of flowing water ecology in the river course is mainly composed of aquatic biological systems in the river, including decomposers, producers and consumers, and other aquatic organisms that affect them. Survival environmental conditions, material metabolism raw materials and other factors. On the other hand, it is the construction of river bank ecology. The river revetment is the transition zone between the river and the land, which closely connects the land and water belts. It is the outer boundary condition of the water movement of the ecological river and the key zone for the stability of the ecological river. The river revetment belt is mainly composed of slope protection, small animals, aquatic ...
