Specific implementation mode

[0035] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments, but it shall not be used as a basis for any limitation on the utility model.

[0036] Refer to the attached Figure 1 As shown, an ecological pile-slab retaining wall includes a concrete column 1 and retaining plates located between adjacent concrete columns 1. A plurality of retaining plates are provided and arranged in sequence up and down.

[0037] The concrete column 1 includes an above-ground part 11 of the concrete column and an underground part 12 of the concrete column. As Figure 3 shown, the embedding depth of the underground part 12 of the concrete column is determined according to construction requirements, and its cross-section is rectangular; as Figure 2 shown, the cross-section of the above-ground part 11 of the concrete column is rectangular with a groove 13 provided on the side surface, and the grooves 13 of the above-ground parts of two adjacent concrete columns 1 are arranged oppositely. The groove 13 is provided for fixing the retaining plate, limiting the retaining plate front and back, and providing reliable support for the retaining plate.

[0038] Furthermore, the groove 13 extends along the height direction of the concrete column 1 in length and is inclined, forming an angle of 75° - 80° with the horizontal plane. The front and back width of the groove 13 is about 1.00 m, slightly larger than the front and back width of the retaining plate, and the depth of the groove 13 is 0.25 - 0.30 m.

[0039] The retaining plate is a trough-shaped retaining plate 2, which is a precast structure, and its shape and structure are as Figure 6 、 7 shown. The height of the front side plate of the trough-shaped retaining plate 2 is lower than the height of the rear side plate, and both the left and right sides of the trough-shaped retaining plate 2 are open. According to whether a drainage trough 221 is provided on the upper surface of the rear side plate of the trough-shaped retaining plate 2, the trough-shaped retaining plate 2 is divided into two types. The structure of the first type of retaining plate 21 is as Figure 6 shown, and the upper surface of its rear side plate is flat without a drainage trough provided; the structure of the second type of retaining plate 22 is as Figure 7 shown, and a plurality of drainage troughs are opened on the upper surface of its rear side plate.

[0040] Specifically, the total height of the front side plate of the trough-shaped retaining plate 2 is 0.45 - 0.50 m, the total height of the rear side plate is 1.2 - 1.25 m, and the total width of the front and rear is 0.95 m - 1.05 m. To facilitate the installation of the trough-shaped retaining plate 2, a clearance L1 = 0.05 m is left between the trough-shaped retaining plate 2 and the groove 13. The radius of the water discharge trough is 0.05 m.

[0041] Both ends of the described trough-shaped retaining plate 2 are respectively assembled in the grooves 13 of adjacent concrete columns 1, and multiple trough-shaped retaining plates 2 are installed one above the other in sequence. After assembly, as Figure 5 shown, the upper layer of trough-shaped retaining plate 2 supports on the rear side plate of the lower layer of trough-shaped retaining plate 2, forming multiple positions for planting plants arranged from top to bottom. And, the first type of retaining plate 21 is located at the top layer, and the rest are the second type of retaining plate 22. The water discharge trough 221 of the second type of retaining plate 22 contacts the bottom surface of the upper layer of retaining plate, forming a water discharge hole. The seepage water in the soil behind the trough-shaped retaining plate 2 flows into the trough of the corresponding trough-shaped retaining plate 2 through the water discharge trough 221 to irrigate the plants therein. As Figure 9 、 10 shown, 0.20 - 0.25 m of planting soil 5 is laid in the trough of each trough-shaped retaining plate 2 for planting suitable plants 4.

[0042] After the trough-shaped retaining plates 2 between adjacent concrete columns 1 are assembled, the angle between the front side plate or the rear side plate of each trough-shaped retaining plate 2 and the horizontal plane is the same as the inclination angle of the groove 13.

[0043] To ensure that groundwater flows into the trough-shaped retaining plate 22 through the water discharge trough 221, a layer of gravel soil 31 with a width of 0.5 m is first laid behind the concrete retaining plate 2. To ensure that the water discharge trough 221 is not blocked by gravel and soil, the gravel soil 31 is wrapped with a geotextile 32, and the back of the gravel soil 31 is ordinary backfill soil 33.

[0044] On the basis of the above embodiments, the described water discharge trough can also be provided on the rear side plate of each trough-shaped retaining plate. In this case, there is no need to distinguish the types of retaining plates, which is conducive to improving the installation efficiency of the retaining plates. Or, the water discharge trough is no longer provided on the rear side plate of the trough-shaped retaining plate, but on the lower surface of the bottom plate of the trough-shaped retaining plate. After the bottom plate of the upper layer of trough-shaped retaining plate supports on the rear side plate of the lower layer of trough-shaped retaining plate, a water discharge hole can also be formed at the position of the water discharge trough.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those of ordinary skill in the art should understand that the specific implementation manners of the present invention can be modified or equivalently replaced with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of the claims pending for approval.
