Description of the embodiments

In order to make the object technical scheme and the beneficial effects of the present utility model clearer, the following detailed description of the preferred embodiments of the present utility model will be given with reference to the accompanying drawings, so as to facilitate understanding of the skilled person.

Referring to fig. 1 to 4, an urban river section structure comprises an ecological frame retaining wall, a plain concrete retaining wall 8 and a slope protection 10. The ecological frame retaining wall sets up in the river course both sides, and as shown in fig. 2 ecological frame retaining wall is by a plurality of ecological frame 2 transversely through side direction connecting bolt 11 interconnect, piles up in the river course both sides in the longitudinal direction for it forms linear river course, not only reduces the river water and erodees the side slope, and linear river course increases the aesthetic property again. As shown in fig. 3, the crushed stone and soil 12 are compacted and backfilled in the ecological frame 2, so that the gravity of the ecological frame 2 is increased, the side slope is stabilized, aquatic plants are planted in the backfilled soil, and not only can habitat of aquatic animals be provided, but also the attractiveness of a river channel is improved. The ecological frame base 1 is further arranged at the bottom of the ecological frame 2, the dry masonry block 3 is further arranged on one side facing the river channel, the gabion 4 parallel to the horizontal line 15 of the river channel is arranged above the dry masonry block 3, the thicknesses of the dry masonry block 3 and the gabion 4 are respectively 70CM and 50CM, flushing of the river channel can be effectively reduced, foot protection of the dry masonry block 3 can be further protected, corrosion of soil in the river channel is prevented, and accordingly river channel safety is guaranteed.

The plain concrete retaining wall 8 is arranged above the rear side slope of the ecological frame 2 retaining wall back to the river course, the plain concrete retaining wall 8 and the ecological frame 2 retaining wall are filled with soil in a layered mode and compacted to form a slope protection 10, a soil bag 14 is further piled up on the upper surface of the slope protection 10 and between the soil layer 13 and the ecological frame 2 retaining wall, a layer of geotechnical cloth 7 is coated between the soil layers 13, turf is further paved on the slope surface of the slope protection 10, water and soil loss of the slope protection 10 and two sides of the river course can be reduced, and stability of the river course is guaranteed.

The slope protection 10 shown in fig. 1 is arranged between the top surface of the slope protection 10 and the plain concrete retaining wall 8 to form a embankment top road 5 on the top surface, households near the river can walk and sightseeing in the embankment top road 5, and the ecological environment of the river is protected, and meanwhile, people are closely contacted with the natural environment, so that a leisure and entertainment platform is practically provided. The dyke top way 5 is faced to river course one side and is set up guardrail 6, protects the resident of sightseeing, avoids falling into the river course, and guardrail 6 bottom is provided with guardrail base 9 and improves the stability of guardrail 6.

As shown in fig. 4, which is a partially enlarged schematic view of the position of the drain pipe 801 of the plain concrete retaining wall 8, it can be seen that the water seepage direction 18 seeps from the soil layer 13 into the drain pipe 801 of the plain concrete retaining wall 8, the large-particle crushed stone 17 is arranged near the water seepage direction 18 from small to large, and the anti-filtration geotechnical cloth 16 is coated in the particles with different sizes of each layer, thereby playing an anti-filtration role and preventing the soil layer 13 of the slope protection 10 from losing into the drain pipe 801.

The river section structure has the characteristics of simplicity, practicability, flexibility, economy, safety, reliability and convenience in construction, ensures the necessary requirements of river transformation, and effectively protects and promotes the ecological protection of cities.

Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the utility model, and that, although the utility model has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the utility model as defined by the appended claims.
