Problems solved by technology

During the construction process of this river channel ecological slope protection scheme, there are problems of large engineering volume and severe soil disturbance caused by large-scale excavation. The water resources of the trees planted on the embankment cannot be guaranteed naturally, their growth and development are slow, and their ability to resist rain and flood erosion is relatively weak. Weak, usually need hand watering and seedling filling

Embodiment 1

[0028] Example 1: Such as figure 1 The ecological slope protection monitoring system established for urban rivers is shown on the slope side of the slope protection on both sides of the river protection, with stagnant aquatic breeding areas 5 arranged at intervals. The stagnant aquatic breeding area 5 needs to be reasonably distributed according to the direction of the river bank and the topography.

[0029] Specifically, such as figure 2 Any stagnant aquatic breeding area 5 shown in the figure is to excavate the slope protection soil foundation 8 outwards to form a recessed area. Different stagnant aquatic breeding areas 5 have different longitudinal spans, usually in slow water areas. span. The scope and scale of stagnant aquatic breeding area 5 should be reasonably arranged according to the needs of ecological construction. By setting stagnant aquatic breeding areas, the river can be formed into multiple stagnant areas, and multiple stagnant areas can be used to establish an...

Embodiment 2

[0036] Embodiment 2: On the basis of the scheme of embodiment 1, a seepage diversion tube 23 is further laid along the slope above the slope anti-seepage membrane, such as Figure 4 As shown, the side wall of the seepage guide tube 23 has seepage holes, and the upper end of the seepage guide tube 23 is inserted into the fiber aquifer 18. With the help of the diversion pipe 23 and the seepage holes on its side wall, the water stored in the water storage ditch 3 is diverted to the rest of the slope protection slope of the river course to increase the water storage and penetration effect.

Embodiment 3

[0037] Embodiment 3: On the basis of the scheme of Embodiment 1, the underground well cover 17 of the rainwater catchment tank 10 is designed as a hollow structure, which is used to collect road rainwater in time and prevent rainwater from being directly discharged into the river channel through the river slope protection. When the net cover 22 is matched and fitted in the rainwater catchment tank 10, the net cover 22 can be pulled out from the rainwater catchment tank 10 as a whole. Workers take out the net cover regularly to clean up the sundries in the net cover and improve the storage capacity and smooth performance. In addition, the rainwater catchment tank 10 may be further provided with an underground catchment channel 11 that is laterally connected to the street well. In order to facilitate the transportation of road stagnant water to the rainwater catchment tank 10 through the confluence, the utilization effect of the rainwater catchment tank 10 is improved. And incre...

Abstract

The invention discloses a monitoring system for ecological slope protection of an urban river. stagnant aquatic breeding areas are arranged at intervals on one side of a river slope protection surface; the stagnant aquatic breeding areas are depression areas formed by excavating a slope protection soil foundation outward horizontally; the surrounding sidewalls of the depression areas are built with stones and cementing materials in a masonry way to form stone masonry depression area protection slopes; a stagnant shallow bank is laid at the bottom of one side, which communicates with the river,of the stagnant aquatic breeding area to maintain minimum ecological water use; the upper side of the shallow bank is fixedly provided with a horizontal net for filtering river floating substances; the meshes of the horizontal net should allow small zooplanktons to pass through; the height of the horizontal net is a little higher than the perennial mean water level of the river; and an external water level sensor, a water quality detector and an oxygen detector are arranged below the water level of the stagnant aquatic breeding areas. The monitoring system disclosed by the invention adopts atreatment technology based on aquatic biological measures, combines terrestrial vegetation ecology with aquatic animal and plant ecology, makes the urban river ecosystem be more complete and more complex, and improves the stability and sustainability of the ecosystem.

Description

Technical field [0001] The invention belongs to the technical field of river ecological monitoring, and specifically relates to a monitoring system applied to perfect ecological slope protection construction and sustainable development of urban rivers. Background technique [0002] At present, river slope protection, especially urban river slope protection, is still a treatment technology based on engineering measures. It only focuses on increasing slope stability, reducing slope exposure, and controlling erosion and collapse through measures. It not only ignores the construction factors of river ecological construction, but also has a strong influence and destruction on the ecological functions of the soil, which cannot meet the requirements of environmental sustainable development. [0003] Traditional mortar-masonry slope protection is to lay the stones flat on the ditch slope, and the pores between the stones are filled with cement mortar to make the entire ditch slope form a w...
