Description

Technical Field

[0001] This invention belongs to the field of roadbed and pavement technology, and particularly relates to a flexible ecological reinforced retaining wall with heavy galvanized steel mesh and its construction method. Background Technology

[0002] In the construction of flexible ecological reinforced retaining walls, the use of heavy-duty galvanized steel mesh walls presents multi-dimensional technical challenges: First, traditional rigid retaining wall structures have high requirements for foundation bearing capacity and lack flexible deformation coordination capabilities. Under soft soil foundations or differential settlement conditions, they are prone to wall cracking, tilting, or even instability, making them difficult to adapt to complex geological environments. Second, conventional reinforced retaining walls often use precast concrete blocks or mortar-grouted rubble masonry, which are not only heavy and have long construction cycles, but also lack ecological compatibility, making it difficult to meet the needs of green highways, sponge cities, and other construction concepts for vegetation restoration and landscape integration. Third, traditional reinforced structures lack systematic and refined design in aspects such as the connection between reinforcement and wall panels, reinforcement tension control, and wall drainage. Connection nodes are prone to stress concentration, reinforcement relaxation, or anchorage failure, directly affecting the overall stability and long-term service performance of the structure.

[0003] Traditional reinforced retaining wall construction methods in such scenarios generally face bottlenecks such as excessive structural rigidity, poor ecological adaptability, and insufficient joint reliability, often leading to a passive situation when dealing with complex foundation conditions and high environmental protection requirements. In addition, existing technologies lack systematic research on the collaborative stress mechanism between galvanized steel mesh wall surface, reinforcement materials, and backfill soil, making it difficult to achieve an organic unity between structural safety and ecological function.

[0004] Therefore, there is an urgent need to develop a flexible ecological reinforced retaining wall with heavy-duty galvanized steel mesh, integrating flexible structural design, ecological wall construction, refined node connection, and life-cycle durability assurance, as well as its construction method. By deeply integrating the rapid assembly technology, reinforcement pre-tensioning system, and multi-layer composite waterproofing and drainage structure mentioned above, the entire process from foundation treatment and reinforcement laying to wall installation can be optimized collaboratively. This has become an urgent need to break through the current technical bottleneck of reinforced retaining walls and promote the development of geotechnical engineering towards a green and low-carbon direction.

[0021] Example 1 As one embodiment, a construction method for a flexible ecological reinforced retaining wall with a galvanized steel mesh facade is proposed, such as... Figure 1-6 As shown, it includes the following steps: S1. Vertically install L-shaped steel mesh panel 1 on foundation 3, and parallelly install connecting mesh plate 6 on foundation 3, connecting the two; use a reinforcement tensioner 9 to hook the reinforcement in L-shaped steel mesh panel 1 and connecting mesh plate 6, and tension the connecting mesh plate 6; specifically, as follows Figure 1-3 As shown, steel mesh panel sealing ends 2 are provided at the ends of L-shaped steel mesh panel 1 and connecting mesh panel 6 respectively; a diagonal tie rod 5 is connected between connecting mesh panel 6 and L-shaped steel mesh panel 1; when implementing the reinforcement pre-tensioning and tightening technology system, a fixing block 11 is provided at the lower part of the reinforcement tensioner 9 to provide stable support during the tensioning process; the left and right ends of the reinforcement tensioner 9 are respectively threaded with a first hook 10 and a second hook 13. By adjusting the rotating threads 12 provided on the first hook 10 and the second hook 13, the extension and retraction length of the hooks is controlled to precisely adjust the tension amount, and the two hooks are driven to move towards or away from each other, thereby completing the reinforcement pre-tensioning and tightening operation; More specifically, such as Figure 5As shown, a rapid assembly technology system for galvanized L-shaped steel mesh panels is implemented. During implementation, L-shaped steel mesh panels 1 are vertically installed on foundation 3, and connecting mesh plates 6 are set parallel to foundation 3 to form a rigid connection structure between the two. To enhance overall stability, steel mesh panel sealing ends 2 are set at the ends of L-shaped steel mesh panels 1 and connecting mesh plates 6, and diagonal tie rods 5 are added between connecting mesh plates 6 and L-shaped steel mesh panels 1 to form a triangular support system. S2. Use the reinforcement tensioner 9 to hook the reinforcement in the L-shaped steel mesh panel 1 and the geogrid 7, and tension the geogrid 7. Install the geogrid 7 at the tail of the connecting mesh panel 6; specifically, as follows... Figure 2 and Figure 3 As shown, a fixing block 11 is provided at the lower part of the reinforcing bar tensioner 9; a first hook 10 and a second hook 13 are threadedly connected to the left and right ends of the reinforcing bar tensioner 9, respectively; the reinforcing bar tensioner 9 is provided on the left side of the connecting mesh plate 6, and a first positioning ruler 15 is provided on the lower right side of the reinforcing bar tensioner 9 to provide an initial positioning reference; a tensioning limit ruler 14 is provided above the first positioning ruler 15 to limit the maximum tensioning stroke; a second positioning ruler 17 is provided on the right side of the connecting mesh plate 6, and is connected to the geogrid 7 through the hook 16 on the second positioning ruler 17; thus, a precise and controllable force transmission path is formed between the reinforcing bar tensioner 9 and the geogrid 7, completing the stable connection between the reinforcing bar and the L-shaped steel mesh panel 1; S3. Backfill the backfill layer 8 in the space formed by the L-shaped steel mesh panel 1, the connecting mesh plate 6, and the tensioned geogrid 7; so that the L-shaped steel mesh panel 1, the connecting mesh plate 6, and the geogrid 7 form an integral reinforced retaining structure that works together to bear the load.

[0022] Example 2 As another embodiment, this second embodiment, based on the first embodiment, proposes a more specific construction method for a flexible ecological reinforced retaining wall with a heavy-duty galvanized steel mesh wall, such as... Figure 1-6 As shown, it includes the following steps: S1. Vertically install L-shaped steel mesh panel 1 on foundation 3, and parallelly install connecting mesh plate 6 on foundation 3, and connect the two; use a reinforcing bar tensioner 9 to hook the reinforcing bars in L-shaped steel mesh panel 1 and connecting mesh plate 6, and tension the connecting mesh plate 6. S2. Use the reinforcing bar tensioner 9 to hook the reinforcing bars in the L-shaped steel mesh panel 1 and the geogrid 7, tension the geogrid 7, and install the geogrid 7 at the tail of the connecting mesh panel 6. S3. Backfill the backfill layer 8 in the space formed by the L-shaped steel mesh panel 1, the connecting mesh panel 6, and the tensioned geogrid 7. S4. Assemble prefabricated trough blocks 30 in the water catchment area behind the wall on the back side of the L-shaped steel mesh panel 1 to form the main body 33 of the diversion channel; specifically, such as Figure 5 and Figure 6 As shown, the prefabricated trough 30 is equipped with a rainwater guide trough 29, and the top of the prefabricated trough 30 is equipped with a drainage cover plate 28, which has drainage holes 27. The splicing surface of the prefabricated trough 30 is equipped with an internal rubber waterstop strip 31. The side wall of the prefabricated trough 30 is equipped with a fastening hinge 32, which is a split structure, consisting of a latch 34 and a locking body 35, to achieve quick assembly and ensure the sealing of the splicing seam. The splicing surfaces of adjacent prefabricated trough 30 are fitted together, and the adjacent latches 34 and locking bodies 35 are locked. A drainage cover plate 28 with drainage holes 27 is installed on the top of the main body 33 of the guide trough, and drainage holes 27 are opened on the drainage cover plate 28 so that the surface rainwater flows into the rainwater guide trough 29 through the drainage holes 27 and is discharged in an orderly manner. More specifically, such as Figure 5 and Figure 6 As shown, the L-shaped steel mesh panel 1 is located on the outermost side of the retaining wall, i.e., the side exposed to the air. The water collection area behind the wall is located directly behind the L-shaped steel mesh panel 1, i.e., the side closest to the soil. The L-shaped steel mesh panel is the wall surface, and the top surface of the backfill soil is the ground behind the wall. When it rains, the water falling on the wall surface flows down along the wall surface and flows directly onto this ground behind the wall. The water falling on the ground behind the wall also collects here. The rainwater diversion trough 29 is installed at the root position where this wall surface and the ground behind the wall meet. S5. Lay a road surface layer 19 and a settlement road surface layer 25 on the backfill layer 8. The settlement road surface layer 25 is adjacent to the main body of the diversion channel 33. The road surface layer 19 and the settlement road surface layer 25 are connected by a rigid support frame and waterproofed. Specifically, as shown in the figure... Figure 4 As shown, the rigid support frame includes a stainless steel sliding plate 18 and a platform-type steel frame 24; two symmetrical platform-type steel frames 24 are set between the road surface layer 19 and the settlement road surface layer 25, and the stainless steel sliding plate 18 is fixed between the tops of the platform-type steel frames 24 to form a rigid support frame; the bottom of the platform-type steel frame 24 is provided with a grooved fixing connection 20, and a waterproof strip 23 is installed between the grooved fixing connection 20 on both sides; a sealant adhesive layer 22 is applied to the side walls of the road surface layer 19 and the settlement road surface layer 25 below the waterproof strip 23; between the road surface layer 19 and the settlement road surface layer 25 with the sealant adhesive layer 22 applied, a polyethylene foam board filling layer 26 and a sealant filling layer 21 are poured from bottom to top to form a multi-layer composite waterproof sealing structure, which is used to eliminate the deformation stress of the platform-type steel frame 24 and block the water seepage channel; More specifically, such as Figure 1 and Figure 4As shown, the flexible ecological mat 4 is laid on the outer facade of the heavy-duty galvanized L-shaped steel mesh panel 1, ensuring a tight fit between the ecological mat and the steel mesh panel surface, forming a three-in-one ecological protection layer of "wall protection - vegetation growth - soil stabilization". The flexible ecological mat 4 is composed of a biodegradable fiber base layer, a mixed grass seed layer, and a nutrient and water-retaining layer. Anchor strips are installed at its bottom, and its top is anchored to the connecting mesh panel 6 or the shoulder structure. The flexible ecological mat 4 is laid after the S4 prefabricated rainwater drainage ditch is installed, i.e. After the rainwater drainage channel 29 and drainage cover 28 are installed and the drainage path is formed, the ecological mat is laid with netting to ensure that the ecological mat is not damaged by rainwater and to provide a stable attachment environment for grass seed germination. After the ecological mat is laid, planting soil is covered on its surface and water is sprinkled for maintenance, so that the roots of the vegetation can extend into the backfill layer 8 along the gaps in the steel mesh panel, forming a synergistic anchoring effect with the geogrid 7 and L-shaped steel mesh panel 1, which can further enhance the overall stability of the retaining wall while achieving rapid greening of the wall.

[0023] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 1 can be referred to each other, and will not be repeated in this application.

[0024] Example 3 As another embodiment, this third embodiment proposes, based on the second embodiment, a flexible ecological reinforced retaining wall with a galvanized steel mesh wall, such as... Figure 1-6 As shown, it includes a rapid assembly technology system for galvanized L-shaped steel mesh panels, a pre-tensioning and tightening technology system for reinforcing bars, a connection technology system for reinforcing bars and L-shaped steel mesh panels, a deformation prevention technology system for the lower platform steel frame of roadbed filling engineering, and a prefabricated assembly-type diversion rainwater trough technology system.

[0025] like Figure 1 As shown, the rapid assembly technology system for heavy-duty galvanized L-shaped steel mesh panels involves vertically installing L-shaped steel mesh panels 1 on the foundation 3, and parallelly installing connecting mesh plates 6 on the foundation 3, forming a rigid connection structure between the connecting mesh plates 6 and the L-shaped steel mesh panels 1. Steel mesh panel sealing ends 2 are respectively installed at the ends of the L-shaped steel mesh panels 1 and the connecting mesh plates 6 to seal the panel ends and enhance overall stability. Diagonal tie rods 5 are installed between the connecting mesh plates 6 and the L-shaped steel mesh panels 1 to form a triangular support system. Geogrid 7 is laid at the tail of the connecting mesh plates 6, and backfill layers 8 are backfilled in layers on the geogrid 6, so that the L-shaped steel mesh panels 1, the connecting mesh plates 6, and the geogrid 7 form a synergistically stressed integral reinforced retaining structure.

[0026] like Figure 2As shown, the pre-tensioning and tightening technology system for reinforcing bars provides a reinforcing bar tensioner 9; a fixing block 11 is provided at the lower part of the reinforcing bar tensioner 9 to provide stable support during the tensioning process; a first hook 10 and a second hook 13 are respectively provided at the left and right ends of the reinforcing bar tensioner 9 to hook the two ends of the reinforcing bar to be tensioned; both the first hook 10 and the second hook 13 are provided with a rotating thread 12, and the extension and retraction length of the hook is controlled by adjusting the rotating thread 12 to precisely adjust the tension amount; under the adjustment action of the rotating thread 12, the first hook 10 and the second hook 13 are driven to move towards or away from each other, thereby completing the pre-tensioning and tightening operation of the reinforcing bar.

[0027] like Figure 3 As shown, the connection system between the reinforcing bar and the L-shaped steel mesh panel 1 includes a reinforcing bar tensioner 9 on the left side of the connecting mesh panel 6, and a first positioning ruler 15 on the lower right side of the reinforcing bar tensioner 9 to provide an initial positioning reference during tensioning. A tensioning limit ruler 14 is set above the first positioning ruler 15 to limit the maximum tensioning stroke of the reinforcing bar tensioner. A second positioning ruler 17 is set on the right side of the connecting mesh panel 6, and a detachable connection is formed between the second positioning ruler 17 and the geogrid 7 through the hook 16 on the second positioning ruler 17. This creates a precise and controllable force transmission path between the reinforcing bar tensioner 9 and the geogrid 7, thus completing the stable connection between the reinforcing bar and the L-shaped steel mesh panel 1.

[0028] like Figure 4 As shown, the subgrade steel frame anti-deformation technology system of the reinforced roadbed filling project consists of two symmetrical steel frames 24 set between the road surface layer 19 and the settlement road surface layer 25. The steel frames 24 are fixed in preset positions by stainless steel sliding plates 18 to form a rigid support skeleton. The steel frames 24 are provided with grooved fixing connection points 20, and waterproof strips 23 are installed at the grooved fixing connection points 20 on the left and right sides. At the bottom of the waterproof strips 23, a sealant filling layer 21, a polyethylene foam board filling layer 26 and a sealant adhesion layer 22 are set in sequence to form a multi-layer composite waterproof sealing structure to eliminate the deformation stress of the steel frames 24 and block the seepage channels.

[0029] like Figure 5 , Figure 6As shown, the prefabricated assembled rainwater drainage system provides a drainage channel body 33, and a rainwater drainage channel 29 is set inside the drainage channel body 33 to form a rainwater collection and discharge channel. The drainage channel body 33 is composed of multiple assembled channel blocks 30 spliced ​​together. Fastening hinges 32 and built-in rubber waterstop strips 31 are set at the splicing points of adjacent assembled channel blocks 30. The fastening hinges 32 are locked by a locking buckle 34 and a locking body 35 to achieve quick assembly and ensure the sealing of the splicing seam. A drainage cover plate 28 is set on the upper part of the rainwater drainage channel 29, and drainage holes 27 are opened on the drainage cover plate 28 so that surface rainwater flows into the rainwater drainage channel 29 through the drainage holes 27 and is discharged in an orderly manner.

[0030] It should be noted that the parts in this embodiment that are the same as or similar to those in Embodiment 2 can be referred to each other, and will not be repeated in this application.
