DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the urban road slope protection design structure in this embodiment includes a main drainage ditch 1 and an auxiliary drainage ditch 2 which are alternately spaced and longitudinally arranged on the slope surface, a planting area is arranged between the main drainage ditch 1 and the auxiliary drainage ditch 2, a first shoulder block 3 is arranged at the top of the planting area and at the top of the slope, a second shoulder block 4 is detachably arranged at the top of the auxiliary drainage ditch 2 and at the top of the slope, and a drainage channel 5 is arranged horizontally at the bottom of the slope.

[0027] By setting the main drainage ditch 1, the auxiliary drainage ditch 2 and the planting area on the slope surface, when the rainfall is small, the rainwater on the top of the slope flows into the drainage channel 5 through the main drainage ditch 1. When the rainfall is heavy, the second shoulder block 4 is removed, and the rainwater on the top of the slope flows into the drainage channel 5 through the main drainage ditch 1 and the auxiliary drainage ditch 2, thereby effectively improving the drainage efficiency of the slope.

[0028] In this embodiment, the planting area includes a planting frame 6 fixed on the slope surface and a plurality of branch ditches 7 obliquely arranged between the main drainage ditch 1 and the auxiliary drainage ditch 2. Plants are planted in the planting frame 6. Both ends of the branch ditches 7 are connected with the main drainage ditch 1 and the auxiliary drainage ditch 2, and one end of the branch ditch 7 close to the auxiliary drainage ditch 2 is lower than the other end, so that rainwater in the main drainage ditch 1 is diverted to the auxiliary drainage ditch 2 through the branch ditch 7, thereby reducing the drainage pressure of the main drainage ditch 1.

[0029] By setting up the branch ditch 7, when the rainfall is heavy, if there is no time to remove the second shoulder block 4, the rainwater in the main drainage ditch 1 can be diverted to the auxiliary drainage ditch 2 through the branch ditch 7, and then flow into the drainage channel 5, thereby reducing the drainage pressure of the main drainage ditch 1.

[0030] In the present utility model, if Figure 2 , Figure 3 As shown, the planting frame 6 includes an outer frame 8 that is continuously or independently arranged, and the outer frame 8 is provided with a drainage hole 9. Specifically, in the present embodiment, the planting frame 6 between adjacent main drainage ditches 1 and auxiliary drainage ditches 2 includes two rows of continuously arranged outer frames 8, and the planting frame 6 between two adjacent branch ditches 7 is in a parallelogram structure. A ground nail 13 is fixed to the bottom of the outer frame 8, and an anti-slip barb (not shown in the figure) is arranged on the outer side of the lower end of the ground nail 13. The ground nail 13 is inserted into the slope body, thereby fixing the planting frame 6 on the slope surface. By providing a drainage hole 9 on the planting frame 6, rainwater can enter or be discharged from the planting frame 6 through the drainage hole 9. On the one hand, when the rainfall is small, it is convenient for rainwater to enter the planting frame 6 to irrigate the plants, and the rainwater is effectively utilized; on the other hand, when the rainfall is large, it is convenient for rainwater to flow out of the planting frame 6 to prevent the plants from being soaked by rainwater, which affects the growth of the plants.

[0031] In this embodiment, a fixing frame is fixed inside the outer frame 8, and the fixing frame includes a fixing sleeve 10 and a connecting rod 11 fixed to the outside of the fixing sleeve 10. The connecting rod 11 is fixedly connected one by one with the edge of the outer frame 8 surrounded by the outside of the fixing sleeve 10. Preferably, the connecting rod 11 is fixed to the middle of the outer frame 8, so that the lower surface of the connecting rod 11 is suspended in the air, which is convenient for rainwater to pass through, and the lower surface of the fixing sleeve 10 abuts against the slope surface. An anchor rod 12 is inserted into the fixing sleeve 10, and the fixing frame is fixedly connected to the slope surface through the anchor rod 12. Preferably, an anti-slip barb (not shown in the figure) is provided on the outer side of the lower end of the anchor rod 12. By providing a fixing frame and an anchor rod 12, the stability and safety performance of the planting frame 6 can be effectively improved.

[0032] In practical applications, when the planting frames 6 at the top and bottom of the slope surface are not complete, the outer frame 8 can be spliced ​​with the first shoulder block 3 or the bottom of the slope.

[0033] In this embodiment, if Figure 4As shown, a clamping block 18 is fixedly provided on both sides of the second shoulder stopper 4 near the first shoulder stopper 3, and the clamping block 18 extends to the upper and lower end surfaces of the second shoulder stopper 4 and is flush with the upper and lower end surfaces of the second shoulder stopper 4. A clamping slot is provided on the side of the first shoulder stopper 3 adjacent to the second shoulder stopper 4 near the second shoulder stopper 4, and the upper end of the clamping slot passes through the upper end of the first shoulder stopper 3, the height of the clamping slot is the same as the height of the clamping block 18, and the shape and size of the cross section of the clamping slot are adapted to the shape and size of the cross section of the clamping block 18. Specifically, the shape of the cross section of the clamping slot and the shape of the cross section of the clamping block 18 are both T-shaped structures. The second shoulder stopper 4 can be installed and removed by moving it up and down. When the second shoulder stopper 4 is in the installed state, the second shoulder stopper 4 is flush with the upper surface of the first shoulder stopper 3.

[0034] By setting a removable second shoulder block 4, when the precipitation is small, the second shoulder block 4 can block rainwater from flowing into the auxiliary drainage ditch 2 from the top of the slope, so that as much rainwater as possible flows into the main drainage ditch 1, and is diverted to the branch ditch 7 through the main drainage ditch 1. The rainwater in the main drainage ditch 1 and the branch ditch 7 enters the planting frame 6 through the leakage hole 9 as much as possible to water the plants. When the precipitation is large, the second shoulder block 4 is removed, and the rainwater on the top of the slope is directly discharged through the main drainage ditch 1 and the auxiliary drainage ditch 2, which speeds up the drainage efficiency, prevents rainwater from scouring the entire slope surface, and avoids affecting the service life of the urban road slope protection design structure.

[0035] In this embodiment, if Figure 5 As shown, the corresponding slope below the planting frame 6 is, from bottom to top, the original soil layer 14, the geotextile layer 15, the transition layer 16 and the planting soil layer 17. The upper surface of the original soil layer 14 is a wavy structure, and the geotextile layer 15 is laid on the original soil layer 14 in a wavy structure. The corresponding slopes below the main drainage ditch 1, the auxiliary drainage ditch 2 and the branch ditch 7 are, from bottom to top, the original soil layer 14, the geotextile layer 15, the transition layer 16 and the concrete layer (not shown in the figure). The bottoms of the ground nails 13 and the anchor rods 12 are inserted into the transition layer 16 above the geotextile layer 15. Specifically, the transition layer 16 can be a sandy protective layer or a gravel layer. The geotextile layer 15 adopts a waterproof geotextile to effectively prevent rainwater from seeping into the slope and causing landslides. The wavy structure of the upper surface of the original soil layer 14 can improve the stability between the geotextile layer 15 and the original soil layer 14 and prevent the waterproof geotextile from shifting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
