Description

Technical Field

[0002] An ecological retaining wall is a form of retaining wall that combines engineering structures with ecological environmental protection. It aims to prevent soil erosion while promoting vegetation growth and improving environmental quality. It is usually used in slope stability projects such as highway, railway slopes, and river revetments.

[0003] To ensure the stability of these slopes, traditional retaining walls are usually built by piling up stones and mortar. However, due to limited stone production, difficulty in finding labor, many late-stage diseases, and difficulty in ecological greening, it is becoming increasingly unsuitable for modern transportation construction. Existing ecological retaining walls are usually prefabricated, and multiple retaining wall modules are spliced to form a retaining wall, which is simple and efficient in construction. However, during the splicing process of existing ecological retaining walls, only the retaining wall modules on the same layer are in a mutually clamped relationship, and there is usually no connection relationship between the retaining wall modules on the upper and lower layers, and the multi-layer retaining wall modules cannot be integrally reinforced. If the foundation in some areas collapses, the retaining wall in this area is likely to become unstable and collapse, and the supporting strength and bearing capacity of the retaining wall are low.

Detailed Description of the Invention

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the specific embodiments of the present invention in detail with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 , an assembled ecological retaining wall, including a support base 1, and further including a retaining unit 2, the retaining unit 2 is arranged on the support base 1, the retaining unit 2 includes a plurality of precast retaining blocks 21, and the plurality of precast retaining blocks 21 are in contact with each other horizontally and are spliced in a stepped manner vertically to form a retaining wall (as shown in Figure 3 and Figure 4 ), a planting cavity 211 for planting plants is provided on the precast retaining block 21, two symmetrically distributed limiting convex blocks 213 are integrally formed at the lower end of the front side wall and the upper end of the rear side wall of the precast retaining block 21, a bottom sealing member 215 for covering the bottom of the planting cavity 211 is integrally formed at the lower end of the precast retaining block 21, the lower end of the bottom sealing member 215 is provided with an inclined surface, and a reinforcing rib is arranged at the connection between the bottom sealing member 215 and the rear side wall of the precast retaining block 21.

[0035] Refer to Figure 2 ,Figure 5 and Figure 6 A stepped joint 216 is formed between the bottom sealing member 215 and the lower limiting convex block 213 on the same precast retaining block 21. A positioning convex block 11 is integrally formed at the upper end of the support base 1, and the positioning convex block 11 is connected to a plurality of stepped joints 216 at the lowermost side at the same time.

[0036] During specific operation, the precast retaining blocks 21 are precast in a precast yard, and then the precast precast retaining blocks 21 are transported to the assembly site by transportation equipment. Subsequently, the ground is excavated for a foundation trench, the foundation is treated, and a cushion layer is laid according to the requirements of conventional retaining wall construction. Then, the support base 1 is poured with concrete. After pouring, the positioning convex block 11 is integrally formed at the upper end of the support base 1 and a position for subsequent pipe fitting installation is reserved. Then, a plurality of precast retaining blocks 21 are selected and placed closely on the support base 1 in sequence. The positioning convex block 11 on the support base 1 is connected to the stepped joint 216 on the precast retaining block 21. The connection can be carried out by means of plug-in fit or cement connection to realize the function of supporting and limiting a plurality of precast retaining blocks 21.

[0037] Refer to Figure 1 、 Figure 5 and Figure 6 A supporting part 22 for supporting the precast retaining block 21 is connected to the rear end of the precast retaining block 21. The supporting part 22 includes a supporting plate 221 integrally formed at the rear end of the precast retaining block 21. A receiving groove 222 is formed on the supporting plate 221. A pressing member 223 is placed in the receiving groove 222. A slope surface that cooperates with the lower inclined surface of the bottom sealing member 215 is provided at the upper end of the pressing member 223.

[0038] Refer to Figure 5 and Figure 6 A foundation reinforcement member 23 is provided at the rear side of a plurality of the precast retaining blocks 21 in each layer. The foundation reinforcement member 23 is placed in a plurality of receiving grooves 222 corresponding to the layers at the same time. The pressing member 223 that cooperates with the plurality of receiving grooves 222 is used to limit the foundation reinforcement member 23.

[0039] During specific operation, after connecting multiple precast retaining blocks 21 in the bottom row to the support base 1, a crushed stone soil cushion layer is laid on the foundation, flush with the supporting plates 221 at the rear ends of the lower precast retaining blocks 21. Subsequently, a foundation strengthening step is carried out. One end of the foundation reinforcement member 23 is placed in the plurality of receiving grooves 222 of the plurality of supporting plates 221. The foundation reinforcement member 23 is a geogrid. The foundation reinforcement member 23 is laid on the crushed stone soil cushion layer. Then, the corresponding plurality of pressing members 223 are placed in the corresponding receiving grooves 222 to press and limit the foundation reinforcement member 23. The pressing member 223 can be an inverted T-shaped structure or a plate-shaped structure. Then, the foundation reinforcement member 23 is tensioned from its free end and fixed with U-shaped nails, so that the foundation reinforcement member 23 is closely attached to the lower crushed stone soil cushion layer. After that, the excavator unloads the crushed stones and soil onto the foundation reinforcement member 23, and manual or mechanical equipment is used for spreading. The foundation reinforcement member 23 improves the connection strength between the multiple precast retaining blocks 21 and the foundation, and water is sprinkled according to the optimal water content of the filler.

[0040] Refer to Figure 1 、 Figure 5 and Figure 6 , the space between two limiting protrusions 213 on the same side is a clamping groove 214, and the clamping groove 214 is in plug-in fit with the two side walls of the two precast retaining blocks 21 that are in contact with each other.

[0041] Refer to Figure 1 、 Figure 5 and Figure 6 , the stepped splicing joint 216 is connected and matched with the two clamping grooves 214 and the two limiting protrusions 213 that abut against the upper ends of the two adjacent lower precast retaining blocks 21.

[0042] During actual operation, in accordance with the steps for installing the first-layer precast retaining blocks 21, a plurality of precast retaining blocks 21 are successively connected to the precast retaining blocks 21 of the first layer. During the splicing process of the upper-layer precast retaining blocks 21, the stepped splicing interfaces 216 on the upper layer are connected to the two clamping grooves 214 at the upper ends of two adjacent precast retaining blocks 21 on the lower layer and the two closely attached limiting protrusions 213. The connection can be carried out by means of plug-in cooperation or cement connection, so that the upper-layer precast retaining blocks 21 are located between two adjacent precast retaining blocks 21 on the lower layer. At the same time, under the combined action of the cooperation between the two closely attached limiting protrusions 213 at the upper ends of two adjacent precast retaining blocks 21 on the lower layer and the stepped splicing interfaces 216, and the plug-in connection between the clamping grooves 214 at the lower ends of the upper-layer precast retaining blocks 21 and the two side walls of two adjacent precast retaining blocks 21 on the lower layer that are in contact, the connection strength between two adjacent precast retaining blocks 21 is effectively improved. The two limiting protrusions 213 at the lower end of the upper-layer precast retaining block 21 cooperate with the bottom sealing member 215 to limit the limiting protrusions 213 at the upper end of the lower-layer precast retaining block 21. The three cooperate with each other to effectively transfer and evenly distribute the load borne, effectively increasing the support strength of the precast retaining blocks 21 after splicing of the upper and lower layers. The slope on the pressing member 223 located on the lower layer supports the inclined surface of the bottom sealing member 215 at the lower end of the upper-layer precast retaining block 21, further strengthening the stress strength of the spliced precast retaining blocks 21. After a plurality of precast retaining blocks 21 are spliced onto the precast retaining blocks 21 of the first layer, the foundation strengthening step is carried out. The precast retaining blocks 21 are prefabricated components, and only need to be spliced on the construction site, and the splicing operation is simple, effectively shortening the construction period.

[0043] Carry out the splicing construction of the upper-layer other-layer precast retaining blocks 21 according to the steps of splicing the first-layer precast retaining blocks 21 and the second-layer precast retaining blocks 21 of the retaining wall, and at the same time carry out the foundation strengthening step to form an ecological retaining wall.

[0044] Refer to Figure 6 , pipe connection channels 212 are provided on both the left and right side walls of the precast retaining block 21.

The irrigation unit 3 includes a porous irrigation pipe 31 that is respectively connected to the pipe connection channels 212 on a plurality of precast retaining blocks 21 of each layer and is used for irrigating the plants in the planting cavity 211. At the same time, a plurality of porous irrigation pipes 31 are used to support a plurality of precast retaining blocks 21, and both ends of a plurality of porous irrigation pipes 31 are simultaneously connected with a connecting member 32 for limiting a plurality of the porous irrigation pipes 31.

[0046] Refer toFigure 1 and Figure 2 The irrigation unit 3 further includes a connecting pipe 34 respectively connected to the ends of a plurality of porous irrigation pipes 31, and a water supply pipe 33 is commonly installed and connected to the lower ends of the plurality of connecting pipes 34.

[0047] During specific operation, after the ecological retaining wall is formed, a plurality of porous irrigation pipes 31 are sequentially selected and respectively inserted into a plurality of pipe connection channels 212 of each layer. The porous irrigation pipes 31 of each layer simultaneously integrally connect a plurality of precast retaining blocks 21 of the corresponding layer. Subsequently, two connectors 32 are fixedly connected to the two ends of the plurality of porous irrigation pipes 31 by welding or fixing devices to realize the integral connection of the plurality of porous irrigation pipes 31, further enhancing the overall support strength and bearing capacity of the ecological retaining wall, effectively avoiding the phenomenon that part of the wall of the ecological retaining wall sinks or the whole collapses due to slight subsidence of the local foundation, and the plurality of pipe connection channels 212 support the porous irrigation pipes 31 at multiple points, effectively avoiding the phenomenon that the porous irrigation pipes 31 are bent and improving the stability of the use of the porous irrigation pipes 31. After the installation of the plurality of porous irrigation pipes 31 is completed, the plurality of connecting pipes 34 are sequentially connected to the ends of the plurality of porous irrigation pipes 31 through existing pipe fittings connectors. The structures of the plurality of connecting pipes 34 are the same except for the dimensions. Subsequently, the water supply pipe 33 is arranged at the reserved installation position of the foundation and the support base 1 inside the ecological retaining wall, and then the plurality of connecting pipes 34 are welded or connected to the water supply pipe 33 through pipe fittings connectors. Subsequently, the plurality of connecting pipes 34 and the water supply pipe 33 are filled with soil and compacted. The water supply pipe 33 is provided with a valve by itself and is connected and communicated with an existing water pipe at the lower end.

[0048] After the pipeline is laid, the prepared cultivated soil is filled into the planting cavity 211, and green landscape plants are planted. According to the growth situation of the plants, replanting, watering, fertilizing, and pest control are carried out until the vegetation grows stably, and the ecological retaining wall is assembled and completed.

[0049] In addition, the present invention also provides an assembly construction method for an assembled ecological retaining wall, which specifically includes the following steps: S1: Precast the precast retaining blocks 21 and the supporting parts 22 in a prefabrication yard, and perform post-curing to ensure the strength.

The multiple precast retaining blocks 21 are in close contact with each other. Subsequently, lay a crushed stone and soil cushion on the base, flush with the supporting plate 221 at the rear end of the lower precast retaining block 21. Then, lay the foundation reinforcement member 23 on the crushed stone and soil cushion and place it in the accommodating groove 222. Next, place the pressing member 223 in the accommodating groove 222 to limit the foundation reinforcement member 23, and invert and mechanically compact the backfill to limit the upper end of the reinforcement member.

[0052] S4: Carry out the splicing construction of the other upper layers of precast retaining blocks 21 according to the steps of splicing the first layer of precast retaining blocks 21 of the retaining wall. The precast retaining blocks 21 of the upper and lower adjacent layers are placed staggeredly.
