Prefabricated assembly box ecological retaining wall

Abstract

This invention relates to the field of prefabricated box wall technology, specifically a prefabricated prefabricated box-type ecological retaining wall. It includes a main component comprising a retaining wall body, vertically chiseled fixing holes, and a hoisting opening; a fixing component comprising a recessed platform and a docking platform located on the inner wall of the recessed platform; and an external protrusion opposite the recessed platform, the inner wall of which has an internal cavity, an internal plate, and an internal locking element on its end face. By using the inclined surface cooperation between the external protrusion and the recessed platform, and the precise alignment of the docking sleeve and the limiting sleeve, the traditional manual measurement and adjustment method is replaced, significantly shortening the positioning time of a single retaining wall section and avoiding misalignment between upper and lower layers due to human error. Simultaneously, the internal locking element is integrated within the internal cavity of the external protrusion, eliminating the need for additional external support components, reducing construction steps, and not occupying surface space of the retaining wall body.

Description

Technical Field

[0001] This invention relates to the field of prefabricated box wall technology, and in particular to a prefabricated box-type ecological retaining wall. Background Technology

[0002] Prefabricated modular ecological retaining walls are widely used in municipal slope and water conservancy revetment projects due to their advantages such as modular construction and eco-friendliness. However, existing technologies have the following problems: First, the horizontal alignment of multi-layered boxes is inefficient and inaccurate. Traditional assembly relies on manual measurement and adjustment of the horizontal position of upper and lower layers or adjacent boxes, which is not only time-consuming, but also difficult to guarantee stable accuracy when constructing in complex terrains (such as riverbanks and high slopes). Second, the temporary fixing methods of adjacent boxes can easily interfere with the ecological structure. Existing temporary fixing methods mostly use external supports or binding components, which are cumbersome to operate. Disassembly can easily obstruct or damage the ecological reserved structures (such as planting troughs and permeable holes) on the surface of the box, thereby affecting the uniformity of subsequent ecological media (topsoil, grass seeds, etc.) filling and the vegetation growth effect, thus restricting the assembly efficiency and the stability of ecological functions. Summary of the Invention

[0012] As a preferred embodiment of the prefabricated assembled box-type ecological retaining wall of the present invention, wherein: the inner wall of the outer protrusion is provided with an internal cavity and the internal plate is provided on the inner wall of the internal cavity; the outer wall of the internal plate is provided with a slider and the end of the slider extends to the inner wall of the groove opened in the inner wall of the internal cavity and slides with it; the end face of the internal plate is provided with a third elastic element and the third elastic element is sleeved on the outer wall of the movable sleeve.

[0013] As a preferred embodiment of the prefabricated assembled box-type ecological retaining wall of the present invention, wherein: the concave platform end face is provided with a first mounting plate and the first mounting plate end face is provided with a first mounting hole and is provided in the first mounting groove opened on the end face of the retaining wall body; the inner wall of the concave platform is provided with an inner inclined surface and the inner inclined surface cooperates with the outer inclined surface provided on the outer wall of the convex platform.

At the same time, the inner locking component is integrated into the inner cavity of the outer boss, eliminating the need for additional external support components, reducing construction steps, and not occupying the surface space of the retaining wall body. This avoids obscuring the vertical chisel marks and reserves complete space for subsequent ecological functions, balancing assembly efficiency and ecological compatibility. In terms of disassembly and structural reliability, the inner locking component can be automatically triggered by the pressure of the hoisting and lowering during assembly, and achieves stable engagement by relying on the elastic component and the inclined surface cooperation, ensuring a temporary locking effect. During disassembly, only the upper retaining wall needs to be hoisted, and the inner locking component can be automatically released by the reset of the third elastic component and the linkage between the moving sleeve and the inner inclined column, without additional operation, which is convenient for construction and adjustment. Furthermore, the outer boss and the inner concave platform are fixed by the mounting plate and the mounting groove, and the inner plate and the sliding groove are slidably connected, making the overall structure firmly connected and further improving the stability of the retaining wall after assembly.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0031] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a prefabricated assembled box-type ecological retaining wall.

[0032] Specifically, the main component 100 includes a retaining wall body 101, vertical chisel grooves 102 on the outer wall of the retaining wall body 101, fixing holes 103 on the end face of the retaining wall body 101, and lifting openings 104 on the outer wall of the retaining wall body 101.

[0033] The fixing component 200 includes a recessed platform 201 and a mating platform 202 disposed on the inner wall of the recessed platform 201;

[0034] The outer protrusion 203 is opposite to the inner concave platform 201. The inner wall of the outer protrusion 203 has an inner cavity 2034 and an inner plate 204 is provided on the inner wall of the inner cavity 2034. The end face of the inner plate 204 is provided with an inner locking component.

[0035] When the retaining wall body 101 is hoisted, the initial positioning is completed by aligning the outer protrusion 203 with the inner concave platform 201. During docking, the inner plate 204 is opposite to the docking platform 202 and the inner locking component is self-locked with the docking column 2022 located on the inner wall of the docking platform 202 to achieve temporary locking of the retaining wall body 101.

[0036] Specifically, the lifting equipment of the external hoisting equipment is precisely connected to the hoisting port 104 opened on the outer wall of the retaining wall body 101 to ensure that the lifting equipment and the hoisting port 104 fit tightly and are balanced under force. The dedicated hoisting port 104 provides a clear stress point, which avoids the retaining wall body 101 from tilting or overturning during hoisting due to the uncertainty of the stress point, reduces construction safety hazards, and at the same time reduces the impact damage to the vertical chisel grooves 102 on the outer wall of the retaining wall body 101, ensuring the integrity of the retaining wall's appearance.

[0037] The hoisting equipment is started to slowly and uniformly lower the retaining wall body 101. During the lowering process, the outer protrusion 203 on the retaining wall body 101 is observed and adjusted to align with the inner concave platform 201 on another retaining wall body 101 until the outer protrusion 203 can be smoothly aligned with the opening of the inner concave platform 201. During the lowering process, the initial positioning is achieved by relying on the structural adaptation of the outer protrusion 203 and the inner concave platform 201, which replaces the traditional method of manual measurement and adjustment using a tape measure and level. This shortens the positioning time of a single retaining wall and avoids misalignment of upper and lower retaining walls caused by manual measurement errors, laying the foundation for subsequent precise docking.

[0038] Continue to slowly lower the retaining wall body 101, so that the outer protrusion 203 gradually embeds into the cavity of the inner recess 201. Since the inner plate 204 is fixed in the inner cavity 2034 of the inner wall of the outer protrusion 203, the movement of the outer protrusion 203 synchronously drives the inner plate 204 to move, until the outer protrusion 203 is embedded into the inner recess 201 to the preset depth. At this time, the end face of the inner plate 204 is completely opposite to the docking platform 202 of the inner wall of the inner recess 201. At this time, through the embedding and cooperation of the outer protrusion 203 and the inner recess 201, the precise alignment of the inner plate 204 and the docking platform 202 is ensured, which provides positional guarantee for the self-locking of the inner locking component and the docking post 2022, and avoids self-locking failure due to alignment deviation.

[0039] The retaining wall body 101 is slowly lowered so that the inner locking component on the end face of the inner plate 204 contacts the docking column 2022 on the inner wall of the docking platform 202. As the lowering action continues, the inner locking component triggers the self-locking mechanism and stably engages with the docking column 2022. Then the hoisting equipment is stopped from lowering. After the lower part is completed, there is no need to install additional external support components, reducing construction steps. At the same time, the inner locking component is located in the inner cavity 2034 of the outer protrusion 203, which does not occupy the surface space of the retaining wall body 101. This avoids the external components from obstructing the vertical chisel grooves 102 and also reserves complete space for the subsequent ecological functions of the retaining wall, taking into account both engineering assembly efficiency and functional adaptability. Example 2

[0040] Reference Figures 5-7 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0041] Specifically, the inner locking component includes a movable column 205 movably disposed on the inner wall of the inner plate 204, with the end of the movable column 205 extending to the end of the inner plate 204 and provided with a limiting sleeve 2051. The inner wall of the limiting sleeve 2051 is provided with a mating cavity 2052, and the inner wall of the mating cavity 2052 is provided with a movable block 2053. The end of the movable block 2053 is also provided with a first elastic element 2054.

[0042] The movable column 205 and the limiting sleeve 2051 are an integral unit. The movable column 205 moves within the surface of the built-in plate 204 and drives the limiting sleeve 2051 to move as a whole.

[0043] The movable block 2053 is symmetrically arranged on the inner wall of the limiting sleeve 2051 and is pushed by the first elastic element 2054 installed on its outer wall to extend the front end of the movable block 2053 into the interior of the docking cavity 2052. When the limiting sleeve 2051 moves downward and the movable block 2053 touches the object, it will retract inward and squeeze the first elastic element 2054 to deform it. The elastic reset of the first elastic element 2054 pushes the movable block 2053 to reset.

[0044] Preferably, the end face of the built-in plate 204 is provided with an inner sleeve 2042 and the end of the movable column 205 is provided on the inner wall of the inner sleeve 2042. The outer wall of the inner sleeve 2042 is also provided with an outer sleeve 2044 and the inner wall of the outer sleeve 2044 is provided with a movable sleeve 206. The end of the movable column 205 is provided with a second elastic member 2055 and the other end of the second elastic member 2055 is in contact with the inner wall of the movable sleeve 206.

[0045] The upper surface of the built-in plate 204 has an array of multiple inner sleeves 2042, and the moving column 205 slides on the inner wall of the inner sleeve 2042.

[0046] The outer wall of the movable sleeve 206 is attached to the inner wall of the outer sleeve 2044 and is also sleeved on the outside of the inner sleeve 2042 and the movable column 205. The second elastic element 2055 at the top of the movable column 205 is located between the movable column 205 and the movable sleeve 206.

[0047] The inner wall of the movable column 205 is provided with an inner inclined column 2056 and the outer wall of the inner inclined column 2056 is provided with a protrusion 2057. The outer wall of the protrusion 2057 is provided with a convex sliding surface 2058 and the convex sliding surface 2058 is in contact with the outer wall of the inner inclined block 2061 provided on the inner wall of the movable sleeve 206.

[0048] The inner inclined column 2056 moves inside the moving column 205 and passes through the limiting groove 2043 on the surface of the inner sleeve 2042. Affected by the limiting groove 2043, the inner inclined column 2056 will only move laterally, and the moving column 205 will move up and down inside the inner sleeve 2042 through the lateral movement of the inner inclined column 2056.

[0049] like Figure 7 As shown, the inner wall of the movable sleeve 206 is provided with an inner inclined block 2061, and the inner inclined block 2061 is in contact with the convex sliding surface 2058 on the outer wall of the inner inclined column 2056 and slides together; when the movable sleeve 206 moves, through the cooperation of the inner inclined block 2061 and the convex sliding surface 2058 on the inner wall, the inner inclined column 2056 is driven to move laterally inside the limiting groove 2043, and the movable column 205 drives the limiting sleeve 2051 to move upward inside the inner sleeve 2042.

[0050] The retaining wall body 101 has a second mounting groove 106 at one end and a second mounting plate 2032 on the outer protrusion 203 and is mounted on the inner wall of the second mounting groove 106. The outer wall of the second mounting plate 2032 has a second mounting hole 2033.

[0051] The outer boss 203 is installed and fixed in the second mounting groove 106 by the second mounting plate 2032 on the top, and is screwed and fixed by the second mounting hole 2033 on the surface of the second mounting plate 2032.

[0052] During assembly, the lower surface of the bottom retaining wall body 101 does not need to be equipped with the outer protrusion 203. It can be directly hoisted and placed by the hoisting equipment. The bottom of the retaining wall body 101 that is hoisted and arranged later is then equipped with the outer protrusion 203 to achieve initial positioning and temporary fixation.

[0053] Preferably, the inner wall of the outer boss 203 has an inner cavity 2034 and an inner plate 204 is disposed on the inner wall of the inner cavity 2034. The outer wall of the inner plate 204 is provided with a slider 2041 and the end of the slider 2041 extends to the inner wall of the groove 2035 opened in the inner wall of the inner cavity 2034 and slides with it. The end face of the inner plate 204 is provided with a third elastic member 207 and the third elastic member 207 is sleeved on the outer wall of the movable sleeve 206.

[0054] The built-in plate 204 slides up and down inside the built-in cavity 2034 via the slider 2041 on the outer wall. Meanwhile, the third elastic member 207 is located between the upper surface of the built-in plate 204 and the top of the built-in cavity 2034. When the built-in plate 204 moves upward, the third elastic member 207 is compressed first. After the built-in plate 204 moves up to a certain height, it will touch the top of the movable sleeve 206 and bring the movable sleeve 206 closer to the surface of the built-in plate 204.

[0055] In summary, during assembly, the lower surface of the bottom retaining wall body 101 does not require the installation of the outer protrusion 203; it can be directly placed using hoisting equipment. Subsequently, the bottom of the upper retaining wall bodies 101 is embedded into the second mounting groove 106 at the end of the retaining wall body 101 via the second mounting plate 2032 at the top of the outer protrusion 203. Bolts are then used to secure the outer protrusion 203 to the retaining wall body 101, forming a unified structure. The end of the movable column 205 is located at the end of the built-in plate 204. The inner wall of the inner sleeve 2042 can slide along the inner sleeve 2042; the moving column 205 and the limiting sleeve 2051 are integral structures, and the moving blocks 2053 on the inner wall of the limiting sleeve 2051 are symmetrically distributed. They are pushed by the first elastic element 2054 at their ends, and the front end of the moving block 2053 extends into the docking cavity 2052; one end of the second elastic element 2055 at the top of the moving column 205 contacts the moving column 205, and the other end contacts the moving sleeve 206 on the inner wall of the outer sleeve 2044, and is in an undeformed state;

[0056] The built-in plate 204 is placed in the groove 2035 of the built-in cavity 2034 of the outer boss 203 via the outer wall slider 2041. The third elastic element 207 is sleeved on the outer wall of the movable sleeve 206, with one end in contact with the end face of the built-in plate 204 and the other end in contact with the top of the built-in cavity 2034, and is in an uncompressed state.

[0057] When the hoisting equipment is started to lower the upper retaining wall body 101, the outer protrusion 203 is gradually embedded into the inner recess 201 on the upper surface of the lower retaining wall body 101. As the outer protrusion 203 moves down, the limiting sleeve 2051 aligns with the docking sleeve 2021 on the docking platform 202 on the inner wall of the inner recess 201. The lowering continues until the limiting sleeve 2051 enters the docking sleeve 2021. The top block 2023 at the end of the docking column 2022 on the inner wall of the docking sleeve 2021 contacts the moving block 2053 in the docking cavity 2052 of the limiting sleeve 2051. The top block 2023 pushes the moving block 2053 into the docking cavity 2052 through its outer wall inclined sliding surface 2024. The moving block 2053 squeezes the first elastic element 2054 to deform it.

[0058] As the retaining wall body 101 continues to be lowered, the built-in plate 204 is pressed from below and slides upward along the groove 2035 on the inner wall of the built-in cavity 2034. The end face of the built-in plate 204 presses against the third elastic element 207 to compress it. When the built-in plate 204 moves up to the preset height, its end face contacts the bottom of the moving sleeve 206. The built-in plate 204 continues to move upward and pushes the moving sleeve 206 to move along the inner wall of the outer sleeve 2044 towards the inner sleeve 2042.

[0059] When the movable sleeve 206 moves, the inner inclined block 2061 on its inner wall slides against the convex sliding surface 2058 on the outer wall of the inner inclined column 2056 of the movable column 205. The inner inclined block 2061 applies a lateral thrust to the protrusion 2057 through the convex sliding surface 2058, which drives the inner inclined column 2056 to move laterally along the limiting groove 2043 on the surface of the inner sleeve 2042. When the inner inclined column 2056 moves laterally, it drives the movable column 205 to move upward along the inner wall of the inner sleeve 2042. The movable column 205 simultaneously drives the limiting sleeve 2051 to move upward.

[0060] At this time, the moving block 2053 is located below the top block 2023 and moves back to the inner wall of the docking cavity 2052. The end face of the moving block 2053 fits against the outer wall of the docking column 2022, locking the docking column 2022 in the docking cavity 2052, realizing the self-locking of the inner locking component and the docking column 2022, thereby completing the temporary locking of the retaining wall body 101. Example 3

[0061] Reference Figures 2-4 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0062] Specifically, the concave platform 201 has a first mounting plate 2011 on its end face, and the first mounting plate 2011 has a first mounting hole 2012 on its end face, which is located in the first mounting groove 105 opened on the end face of the retaining wall body 101. The inner wall of the concave platform 201 has an inner inclined surface 2013, and the inner inclined surface 2013 cooperates with the outer inclined surface 2031 on the outer wall of the outer protrusion 203.

[0063] The concave platform 201 is screwed and fixed inside the first mounting groove 105 on the upper surface of the retaining wall body 101. The inner inclined surface 2013 of the inner surface cooperates with the outer inclined surface 2031 of the outer wall of the outer protrusion 203 on the lower surface of the retaining wall body 101 to be installed. When installing from below, even if the initial hoisting position is incorrect, by fine adjustment, the lower end of the outer protrusion 203 can be made to contact the inner inclined surface 2031 of the inner wall of the concave platform 201, and the positioning installation can be achieved through the cooperation between the inclined surfaces.

[0064] Preferably, the docking platform 202 is fixed to the inner wall of the concave platform 201, and the inner wall of the docking platform 202 is provided with an array of docking sleeves 2021. The docking sleeves 2021 and the limiting sleeves 2051 are positioned opposite each other and are sleeved on the outer wall of the limiting sleeves 2051 when in contact.

[0065] The docking sleeve 2021 is fitted outside the docking column 2022 and is higher than the docking column 2022. It is level with the docking platform 202. When the retaining wall body 101 is installed and lowered, the built-in cavity 2034 at the bottom of the outer protrusion 203 is opposite to the docking platform 202. When it moves down, the docking platform 202 and the docking sleeve 2021 first contact the built-in plate 204 and push the built-in plate 204 to move upward inside the built-in cavity 2034. When the built-in plate 204 moves to a certain height, the inner wall of the built-in cavity 2034 touches the top of the moving sleeve 206 and causes the moving sleeve 206 to move relative to the surface of the built-in plate 204. At this time, the moving column 205 moves upward inside the inner sleeve 2042, and the lower limiting sleeve 2051 moves upward synchronously.

[0066] Preferably, the inner wall of the docking sleeve 2021 is provided with a docking post 2022 and the end of the docking post 2022 is provided with a top block 2023. The outer wall of the top block 2023 is provided with an inclined sliding surface 2024. The outer wall of the docking post 2022 is fitted with a moving ring 2025 and the end of the moving ring 2025 is provided with an upper sliding surface 2026 and a lower sliding surface 2027.

[0067] The upper end of the movable ring 2025 is provided with an upper sliding surface, and the lower end is provided with a lower sliding surface 2027. The movable ring 2025 can move freely up and down on the surface of the docking post 2022.

[0068] In summary, during use, when the retaining wall body 101 is hoisted and installed, the outer protrusion 203 on the lower surface of the retaining wall body 101 is first aligned with the inner concave platform 201. Then, the hoisted retaining wall body 101 is lowered. When the outer protrusion 203 moves down, the inner cavity 2034 is aligned with the docking platform 202. As it continues to be lowered, the limiting sleeve 2051 below the inner plate 204 is fitted onto the outside of the docking column 2022. At this time, the outer wall of the moving block 2053 on the inner wall of the docking cavity 2052 first touches the inclined sliding surface 2024 at the end of the top block 2023, causing the moving block 2053 to move inward and complete the downward movement of the limiting sleeve 2051. After passing the top block 2023, the moving block 2053 is pushed by the reset of the first elastic element 2054, so that its end contacts the outer wall of the docking column 2022.

[0069] The built-in plate 204 on the inner wall of the built-in cavity 2034 contacts the top of the docking platform 202 and the docking sleeve 2021. As the retaining wall body 101 is lowered, the built-in plate 204 is pushed upward. At this time, as the built-in plate 204 moves upward, it first squeezes the upper third elastic element 207, and then touches the top of the moving sleeve 206 and makes the moving sleeve 206 move relative to the built-in plate 204. At this time, the moving column 205 drives the limiting sleeve 2051 to move upward. The moving block 2053 on the inner wall of the limiting sleeve 2051 moves upward along the outer wall of the docking column 2022. When the retaining wall body 101 is completely lowered, the built-in plate 204 stops moving. The outer protrusion 203 and the inner concave platform 201 are assembled and locked by the internal structure, which strengthens the temporary fixation of the retaining wall body 101 and facilitates the subsequent fixation of the retaining wall body 101 through the fixing hole 103 on the surface.

[0070] When disassembly is required, the upper retaining wall body 101 is hoisted. As the upper retaining wall body 101 moves upward, the inner plate 204 is moved downward by the third elastic element 207. At this time, the moving sleeve 206 moves upward relative to the inner plate 204, causing the moving column 205 and the lower limiting sleeve 2051 to move downward. The moving block 2053 on the inner wall of the limiting sleeve 2051 contacts the upper sliding surface 2026, retracts backward, and moves to the lower part of the moving ring 2025. Then it extends again. As the retaining wall body 101 is hoisted and raised, the moving block 2053 rises with the limiting sleeve 2051 and drives the moving ring 2025 to move upward on the surface of the docking column 2022. When the moving ring 2025 is blocked by the top block 2023, the top of the moving block 2053 retracts inward along the lower sliding surface 2027 and causes the limiting sleeve 2051 to disengage from the docking sleeve 2021, thus separating the two.
