Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, and in particular to an ecological self-healing prefabricated retaining wall. Background Technology

[0002] In slope engineering, retaining walls made of cast-in-place concrete are mostly used. However, with the rapid development of the social economy and the rapid advancement of urbanization in various places, the construction and renovation of municipal engineering projects are also accelerating. Traditional cast-in-place concrete retaining walls have gradually shown their drawbacks in actual construction: cast-in-place concrete structures have high requirements for construction sites, the concrete pouring period is too long, and the project cost is high.

[0003] Prefabricated retaining wall panels, manufactured using standardized factory prefabrication and installed on-site, offer unique advantages. Furthermore, in areas with poor foundation conditions and a lack of stone, prefabricated retaining walls are the optimal choice due to requirements for lightweight, compact walls, small footprints, and low foundation bearing capacity. However, existing buttress-type prefabricated retaining walls suffer from problems such as excessive assembly steps, unstable foundations, and poor overall integrity. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a prefabricated ecological retaining wall with stable structure and strong integrity.

[0005] This utility model provides an ecological self-healing prefabricated retaining wall, including a cast-in-place base plate, a prefabricated vertical plate, and a prefabricated back plate. The inclined surface of the prefabricated vertical plate supports the prefabricated back plate, and the bottom of the prefabricated vertical plate is provided with a front toe and a rear toe. It also includes a prefabricated toe plate and a post-cast heel plate. The prefabricated toe plate is fixed to the cast-in-place base plate. The rear part of the prefabricated toe plate is provided with multiple toe grooves. The front toe of the prefabricated vertical plate is inserted into the toe groove. The post-cast heel plate is used to fix the bottom and rear toe of the prefabricated vertical plate by casting.

[0006] As an improvement, the post-cast heel slab is made of reinforced concrete. Multiple reinforcing bars are arranged in two rows at the bottom of the precast slabs. A portion of the main reinforcing bars of the reinforced concrete post-cast heel slab pass through these reinforcing bars on the same axis as the precast slabs, while another portion passes through the gap between the front and rear toes of the precast slabs. The stirrups of the reinforced concrete post-cast heel slab are tied between adjacent precast slabs. This arrangement, with some main reinforcing bars passing through the reinforcing bars of the precast slabs and another portion passing through the gap between the front and rear toes, and the stirrups tied between adjacent precast slabs, creates a more stable integrated structure with the louvered precast slabs, the post-cast heel slab, and the cast-in-place base slab, resulting in stronger overall integrity.

[0007] As an improvement, the top beam is a precast capping slab with multiple grooves at the bottom. The top of the precast vertical slab is embedded in the grooves, and the precast capping slab is bonded and fixed to the precast vertical slab. This ensures a firm connection and good stability between the precast capping slab and the precast vertical slab.

[0008] As an improvement, a plastic steel plate is anchored to the inclined surface of the precast vertical slab that abuts the precast back slab using screws. This is used to position each precast vertical slab after the reinforced concrete is poured and before the heel slab is poured, preventing relative movement.

[0009] Preferably, the precast back panel is placed on the rear toe of the precast upright panel, and the precast back panel and the rear toe of the precast upright panel are fixed together by filling the gap with dry hard concrete and bonding it to secure the precast back panel.

[0010] Preferably, the top beam of the precast vertical slab is set as a precast top block that can be detachably connected to each other. The number of precast top blocks is the same as the number of front toes and rear toes of the precast vertical slab. One side wall of the precast top block is provided with a T-shaped protrusion, and the other side wall is provided with a T-shaped groove that matches the T-shaped protrusion.

[0011] Preferably, the bottom of the precast top block has a groove that matches the thickness of the precast vertical slab, and a rod is installed in the groove. The upper part of the precast vertical slab has a slot for inserting and engaging with the rod. The connection between the precast top block and the precast vertical slab is secure through the insertion and engagement of the rod with the slot on the precast vertical slab.

[0012] Preferably, the top of the precast back panel is provided with limiting protrusions at intervals, and the spacing between the limiting protrusions is the same as the spacing between adjacent precast vertical panels.

[0013] As a preferred option, the top of the precast top block is also equipped with a hook.

[0014] Beneficial effects: 1. Compared with the prior art, the advantages of this utility model are that a precast toe plate is used to cooperate with the front toe of the bottom of the precast vertical plate to initially fix the precast vertical plate, and then the precast vertical plate, the cast-in-place pad plate and the cast-in-place heel plate are integrated through the pouring of the post-cast heel plate, which has strong integrity and stable structure.

[0015] 2. The modular design of prefabricated toe slabs, vertical slabs, back slabs and top beams enables standardized factory production and rapid on-site assembly, which has the advantages of high assembly efficiency and less constraint from the on-site environment. Attached Figure Description

Detailed Implementation

[0024] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0025] like Figures 1-3The first embodiment of an ecological self-healing prefabricated retaining wall is shown, including a cast-in-place base plate 1, a prefabricated vertical plate 2, and a prefabricated back plate 3. The inclined surface of the prefabricated vertical plate 2 supports the prefabricated back plate 3. The bottom of the prefabricated vertical plate 2 is provided with a front toe and a rear toe. It also includes a prefabricated toe plate 4 and a post-cast heel plate 5. The prefabricated toe plate 4 is fixed to the cast-in-place base plate 1. The rear part of the prefabricated toe plate 4 is provided with multiple toe grooves. The front toe of the prefabricated vertical plate 2 is inserted into the toe groove. The post-cast heel plate 5 is used to cast and fix the bottom and rear toe of the prefabricated vertical plate 2. Among them, the precast vertical slab 2 has a louvered design with gaps between them, providing growth space for aquatic animals and plants. Fish nest bricks and microbial carriers can also be placed in the gaps to effectively enhance the ecological function. The precast back slab 3 is preferably a permeable back slab made of sand-free concrete, which has a high permeability while bearing soil pressure, which is conducive to water and soil exchange, enhances the ecological interaction function between the river and the soil, and achieves water permeability but not soil permeability, effectively preventing soil erosion. The precast toe slab 4 is fixed to the cast-in-place pad 1 by multiple short steel bars. The short steel bars are driven into the cast-in-place pad 1 through the pre-reserved holes on the side teeth of the precast toe slab. The precast toe slab 4 can also be fixed to the cast-in-place pad 1 in other ways.

[0026] As an improvement, the post-cast heel slab 5 is a reinforced concrete post-cast heel slab; the bottom of the precast vertical slab 2 is provided with multiple reinforcing bar holes arranged in two rows. A portion of the main reinforcing bars of the reinforced concrete post-cast heel slab passes through the reinforcing bar holes on the same axis of multiple precast vertical slabs 2, and another portion of the main reinforcing bars of the reinforced concrete post-cast heel slab passes through the gap between the front and rear toes below multiple precast vertical slabs 2. The stirrups of the reinforced concrete post-cast heel slab are tied between two adjacent precast vertical slabs 2.

[0027] As an improvement, its top beam 6 is a precast top plate, and the bottom of the precast top plate is provided with multiple grooves 60. The top of the precast vertical plate 2 is embedded in the grooves 60, and the precast top plate and the precast vertical plate 2 are bonded and fixed by dry hard concrete.

[0028] As an improvement, the precast vertical slab 2 is attached to the inclined surface of the precast back slab 3 by screws anchoring the plastic steel plate 7.

[0029] In this embodiment, the precast back plate 3 rests on the rear toe of the precast upright plate 2, and the precast back plate 3 and the rear toe of the precast upright plate 2 are fixed together by dry-hardened concrete grout 8. Of course, the precast back plate 3 and the post-cast heel plate 5 can also be fixed together by dry-hardened concrete grout 8 at the same time.

[0030] like Figures 4-8The diagram shows a second embodiment of an ecological self-healing prefabricated retaining wall. Based on the first embodiment, the top beam 6 of the prefabricated vertical slab 2 is set as a prefabricated top block that can be detachably connected to each other. Compared with the prefabricated top slab, the prefabricated top block has the advantages of small size and light weight, and is more efficient to assemble with the prefabricated vertical slab 2. The number of prefabricated top blocks is the same as the number of front toes and rear toes of the prefabricated vertical slab 2. One side wall of the prefabricated top block is provided with a T-shaped protrusion 61, and the other side wall is provided with a T-shaped groove 62 that matches the T-shaped protrusion 61. During assembly, the T-shaped protrusion 61 and the T-shaped groove 62 slide and cooperate, thereby realizing efficient connection between adjacent prefabricated top blocks.

[0031] As an improvement, the bottom of the precast top block is provided with a groove 60 that is adapted to the thickness of the precast vertical slab 2, and a rod 63 is provided in the groove. The upper part of the precast vertical slab 2 is provided with a insertion groove 21 that is inserted and matched with the rod 63. Through the insertion and matching of the rod 63 with the insertion groove 21 on the precast vertical slab 2, the precast top block and the precast vertical slab 2 are firmly connected.

[0032] As an improvement, the top of the precast back plate 3 is provided with limiting protrusions 31 at intervals. The spacing between the limiting protrusions 31 is the same as the spacing between adjacent precast vertical plates 2. After the precast vertical plate 2 is installed in the groove 60 of the precast top block, the lower end of the precast back plate 3 rests on the rear toe of the precast vertical plate 2. The precast back plate 3 and the inclined surface of the precast vertical plate 2, as well as the limiting protrusions 31 and the back of the precast top block, are bonded and fixed by dry hard concrete grout 8, thereby further fixing the precast top block.

[0033] As an improvement, a hook 64 is also provided on the top of the precast top block, which facilitates the hoisting of the precast top block.

[0034] The prefabricated components of this prefabricated ecological retaining wall are produced under controlled conditions, ensuring the quality and precision of the components. They are also less affected by rain and snow, requiring only on-site transportation for installation, greatly improving construction efficiency and shortening the construction period. The overall construction process reduces construction waste and wastewater generation, helping to alleviate dust and noise pollution at the construction site and minimizing environmental impact. The post-cast heel slab 5 is constructed using a cast-in-place method, making the foundation of this prefabricated ecological retaining wall a unified structure with strong integrity and good stability.

[0035] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
