Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in the field without creative labor are within the scope of protection of the invention.
[40] Embodiment:
[41] This embodiment provides a river structure of the water system around the city that takes into account both the public welfare and the function, as shown in Figure 1, including: the bottom structure of the river channel 1, and the aquatic plant area 2, the riverside trail 3, the gravity retaining wall 4 and the terrestrial plant area 5 set from the river structure to both sides in turn;
[42] As shown in Figure 3 and Figure 4, the aquatic plant area 2 extends from the upper part of the syncline of the bottom structure 1 of the river channel to form the river slope 21; The aquatic plant area 2 comprises a block 22, a reinforcement bar 23, a gabion 24 and an aquatic plant planting soil 25 paved on the gabion 24. The block 1s set in the aquatic plant planting soil 25, and the reinforcement bar 23 is fixedly connected under the block 22 and passes through the gabion 24 and extends below the gabion 24;
[43] As shown in Figure 8, the gravity retaining wall 4 comprises a retaining wall body 41, an occluding member 42 and a retaining wall reinforcement 43. The riverside trail 3 has an occluding groove 31, the occluding member 42 1s arranged in the occluding groove 31, the lower part of the retaining wall body 41 1s arranged in the occluding member 42, and one end of the retaining wall reinforcement 43 extends into the lower part of the retaining wall body 41 and is fixedly connected with the retaining wall body 41. The other end of the retaining wall stiffener 43 passes through the bite member 42 and butts to the riverside trail 3;
[44] The terrestrial plant area 5 includes the terrestrial plant planting soil 51, which is paved on the side of the retaining wall body 41 away from the river slope 21.
[45] As shown in Figure 2, the river bottom structure 1 includes a solid clay 112 filled at the bottom, a wavy pressure groove 113 arranged on the upper surface of the solid clay 112, and a dry paved pebble 111 above the wavy pressure groove 113; The wavy pressing groove 113 cd:503725 increase the fixing effect of the solid clay 112 on the dry paving cobble 111. The dry-paved cobbles 111 are stacked on the wavy pressure channel 113, which are fixed by gravity without additional measures. The fixation method of the wavy pressure channel 113 and the dry-paved cobbles 111 is only applicable to the municipal water conservancy projects with the main function of landscape, and cannot be applied to the river structure with the main function of flood discharge. The gabion 24 is paved with graded crushed stone clay 26 under the gabion 24.
The gabion 24 is internally made of crushed stone and externally made of reinforcement cage welded by reinforcement mesh. The structure has a large dead weight and strong integrity, which is not easy to deform or flow down under the lasting impact of the river. Moreover, the setting of the crushed stone makes the gabion 24 an uncompacted structure, and the internal pores can provide the necessary space for the growth of the roots of aquatic animals and plants. The gabion 24 provides a good growth environment for aquatic plants, which is conducive to the growth and propagation of aquatic plant roots, thus stabilizing the overall structure. The reinforcement bar 23 is installed inside the gabion 24. The reinforcement bar 23 is of a curved reinforcement structure. The lower part of the reinforcement bar 23 is provided with a corner, and one end of the corner is inclined to the side away from the riverside trail 3. Its lower bending can enhance the lateral anti-sliding force of the gabion 24, enhance the stability of the gabion 24, thus strengthening the growth environment of aquatic plants, and thus ensuring the stability of the river structure. The block 22 is a steel structure. The block 22 is welded to the upper part of the reinforcement bar 23, which can effectively prevent the lateral sliding of the aquatic plant planting soil 25 in the initial stage of the structure, ensure the stability of the aquatic plant planting soil 1, provide a stable growth environment for the aquatic plants growing in the aquatic plant planting soil 1, and facilitate the growth of aquatic plants. When the hydrophyte in the hydrophyte planting soil 25 is successfully planted, the hydrophyte roots will extend downward, penetrate the hydrophyte planting soil 25, the gabion 24, and even enter the graded gravel clay 26. During the long-term operation of the river, the aquatic plant area 2 will form a solid whole through the hydrophyte action. The gravity retaining wall 4 gives full play to the position characteristics of each component and realizes the effective diversion of lateral pressure. The retaining wall main body 41 is arranged in the occluding member 42. The upper surface of the occluding member 42 is non-planar design, that is, the surface of the joint between the occludit&/503725 member 42 and the retaining wall main body 41 inclines downward to all directions, and the floating objects and garbage in the river are not easy to accumulate on the surface of the occluding member 42. The upper surface of the occluding member 42 can also be set as a conical surface to reduce the accumulation of floating objects on the occluding member 42. The bite member 42 is installed in the bite groove 31 on the upper side of the riverside trail 3, and the upper surface height of the bite member 42 is slightly higher than the riverside trail 3. The occluding member 42 is occluded with the riverside trail 3, and the retaining wall reinforcement 43 1s connected to the side of the riverside trail 3. The retaining wall reinforcement 3 can transmit and share the lateral pressure on the retaining wall body 41 to ensure the stability of the retaining wall body 1 structure. Aquatic plant area can provide stable growth environment for aquatic plants, provide sufficient space for the growth of aquatic plants, make full use of the solidification characteristics of the root development of aquatic plants and terrestrial plants on the river structure, and realize the function of improving the stability of the river structure; The blocks, reinforcement bars and gabions in this structure can maintain the stability of aquatic plant planting soil and ensure the flourishing growth of terrestrial plants, thus strengthening the stability of river slope; This channel structure ensures the stability of the channel structure and extends the service life of the channel structure. The ecological function of the river is taken into account while meeting the needs of urban greening and citizens' leisure.
[46] Preferably, as shown in Figure 1 and Figure 3, it includes self-stacked stone retaining 6, which is set at the bottom of the slope of the river slope 21. The self-stacked stone retaining 6 is fixed on the top of the graded gravel clay 26 under the action of gravity, and one side depends on the bottom structure of the river channel 1. The other side of the self-stacked stone retaining 6 is connected with the gabion 24 and the aquatic plant planting soil 25. Due to the oblique arrangement of the river slope, the gabion 24 and the aquatic plant planting soil 25 produce side sliding force, and the setting of the graded gravel clay 26 can block the gabion 24. The side of the aquatic plant planting soil 25 slides to the area of the bottom structure 1 of the river channel.
The stability of the gabion 24 and the hydrophyte planting soil 25 is guaranteed, and the stability of the hydrophyte growing environment is also guaranteed.
[47] Preferably, as shown in Figure 10, the terrestrial plant area 5 includes the first terrestrial plant area 52 and the second terrestrial plant area 53. The first terrestrial plant area 52 and th&/503725 second terrestrial plant area 53 are both paved with terrestrial plant planting soil 51. The first terrestrial plant area 52 includes gravel foundation 521 and vent pipe 522. One end of the vent pipe 522 is set in the gravel foundation 521, and the other end is set in the terrestrial plant planting soil 51. The second terrestrial plant area 53 is located at the side of the first terrestrial plant area 52 away from the riverside trail 3. The setting of the first terrestrial plant area 52 can use the position space of the gravity retaining wall 4 and the second terrestrial plant area 53 to propagate terrestrial plants, so as to improve the ecological environment of the river slope; Trees can be planted above the second terrestrial plant area 53, which can not only beautify the landscape of the environment, but also achieve the effect of purifying the air environment. At the same time, the roots of the terrestrial plants continue to flourish with their growth, which can achieve the reinforcement function of the riverside highway 9 and the terrestrial plant area 5. The compactness of the gravel foundation 521 is greater than 0.93. The vent pipe 522 is a PVC (Polyvinylchlorid) pipe with a diameter of 25~40mm. The vent pipe 522 can provide a channel for the root development of the terrestrial plants in the terrestrial plant planting soil 51. With the growth of the terrestrial plants in the terrestrial plant planting soil 51, the roots of the terrestrial plants gradually flourish. The roots of the terrestrial plants will pass through the ventilation pipe 522 to the plain soil compaction layer 11, thus strengthening the structure of the terrestrial plant area 5.
[48] Preferably, as shown in Figure 7, it also includes a diversion pipe 7. One end of the diversion pipe 7 1s set in the retaining wall body 41 and higher than the upper surface of the riverside trail 3. The other end of the diversion pipe 7 is gradually lowered and connected with the main drainage pipe 8. The buried height of the diversion pipeline 7 depends on the water surface control elevation of the river. When the water flow in the river is large, the water in the river will be discharged back to the main drainage pipeline 8 through the diversion pipeline 7 in time to achieve the flood control and flood fighting effect.
