Description

Technical Field

[0001] This invention belongs to the field of road construction technology, and in particular relates to a flexible mold for making curved ramp retaining walls. Background Technology

[0002] In the construction of highways, interchanges, and other road projects, ramps are a crucial component connecting routes at different heights or in different directions. To protect the stability of the ramp subgrade and prevent slope erosion and collapse, retaining walls are typically constructed on the outer side of the subgrade. Traditional retaining walls are mostly straight or composed of simplified, zigzag-shaped precast panels.

[0003] However, the complex and varied planar curves of ramps make it impossible for straight revetment panels to fit tightly to the actual ramp orientation after splicing. This results in noticeable triangular gaps between panels and between panels and the roadbed. These gaps not only affect aesthetics but, more seriously, provide channels for rainwater and soil erosion. Over time, this can lead to the erosion of the roadbed, creating voids and posing a serious threat to the long-term safety and durability of the road.

[0004] In existing technologies, the formation of the curvature of the retaining wall largely relies on manual adjustment and experience-based judgment, making it difficult to precisely control and perfectly match the complex design curves, resulting in insufficient shaping accuracy. Secondly, when the curvature of the ramp changes, the adjustment process of the template is cumbersome and inefficient, and may even require remaking or significantly modifying the mold system, resulting in poor adaptability and high costs. Furthermore, traditional methods often form the curvature by forcibly bending rigid templates with external force, which will generate continuous stress on the template material, easily leading to fatigue damage and shortening its service life.

[0005] To address this, a flexible mold for fabricating curved ramp retaining walls is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a flexible mold for manufacturing curved ramp retaining walls to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides the following solution: A flexible mold for manufacturing an arc-shaped ramp retaining wall includes: an adjustment mechanism electrically connected to a control system, wherein the adjustment end of the adjustment mechanism is provided with the flexible mold; The adjustment mechanism includes multiple extension components, which are arranged sequentially at intervals along the length of the arc-shaped ramp retaining wall, and the extension components are electrically connected to the control system. The flexible mold includes a flexible panel, which is disposed at the extended ends of the plurality of elongation components, and the arc-shaped ramp retaining wall is located on the top surface of the flexible panel. The control system controls the extension length of the elongation component based on the preset curvature of the arc-shaped ramp retaining wall.

[0008] Preferably, the flexible panel is made of PVC.

[0009] Preferably, the extension component includes a storage box with an opening at the top, a lifting bar inside the storage box, and a drive component inside the storage box for driving the lifting bar to move up and down, the drive component being electrically connected to the control system.

[0010] Preferably, the drive assembly includes two drive motors, which are electrically connected to the control system. The two drive motors are symmetrically arranged on two opposing inner sidewalls inside the storage box. The drive motors are located near the top opening of the storage box. A drive gear is coaxially fixed to the output shaft of the drive motor. The drive gear meshes with a rack, which is vertically fixed to the sidewall of the lifting bar.

[0011] Preferably, each of the two opposite sides of the lifting bar is provided with a retaining plate, the retaining plate extending into the tooth groove of the rack, and the retaining plate abutting against the top surface of the storage box.

[0012] Preferably, the bottom surface of the flexible panel is provided with two base plates, which are located on opposite sides of the flexible panel. Each of the two base plates has a sliding groove on the side away from each other. A sliding rod is slidably connected in the sliding groove. A limiting member is detachably connected between the sliding rod and the sliding groove. The two sliding rods are respectively connected to the left template and the right template. Both the left template and the right template are in contact with the flexible panel.

[0013] Preferably, the bottom surface of the flexible panel is provided with multiple intermediate modules, which are arranged sequentially at intervals along the length of the arc-shaped ramp retaining wall. The bottom ends of the left template, the right template, and the multiple intermediate modules are provided with inserts. The inserts correspond one-to-one with the multiple lifting bars. The inserts are adapted to the slots at the top of the lifting bars and can be detachably connected to the slots.

[0014] The left template has multiple protrusions on the side near the flexible panel, and the multiple protrusions are arranged along the length direction of the left template. The right template has multiple grooves on the side near the flexible panel, and the multiple grooves are arranged along the length direction of the right template.

[0015] A method for manufacturing an arc-shaped ramp retaining wall, based on the aforementioned flexible mold for manufacturing arc-shaped ramp retaining walls, comprises the following steps: Based on the required length of the curved ramp retaining wall, a flexible panel is selected and placed on top of multiple extension components. The control system controls the extension length of the extension components based on the preset curvature of the curved ramp retaining wall. Reinforcing steel bars are installed on top of the flexible panel and concrete is poured to produce the curved ramp retaining wall. After the curved ramp retaining wall has been cured for a set time, the curved ramp retaining wall and the flexible panel are separated, and the curved ramp retaining wall is moved to the curing room for another set time of curing.

[0016] Preferably, the curing time for the curved ramp retaining wall is 48 hours before separating it from the flexible panel.

[0017] Compared with the prior art, the present invention has the following advantages and technical effects: First, the operator inputs the design curvature parameters of the curved ramp retaining wall into the control system. Based on this preset curvature, the control system automatically calculates and generates instructions to control the extension length of each of the multiple elongation components spaced at intervals along the length of the retaining wall in the adjustment mechanism. Then, the flexible panel laid on top of all the elongation components hangs naturally under gravity, smoothly fitting onto the adjustment ends of the elongation components at different heights, thus automatically forming a continuous curved working surface that perfectly matches the design curvature. Finally, the construction workers can then tie the reinforcing bars and pour concrete on this precisely formed curved flexible panel, ultimately creating a curved ramp retaining wall that perfectly matches the ramp's orientation.

[0018] By implementing precise digital control of the adjustment mechanism through a control system, the traditional work mode, which relied on manual experience, involved tedious adjustments, and resulted in inaccurate shaping, has been transformed, achieving automation and high precision in the production of curved facing walls. Utilizing the natural deformation characteristics of the flexible panel, discrete adjustable support points are transformed into smooth, continuous curved surfaces. This not only avoids forced bending damage to the mold and extends its service life, but also allows a single mold to quickly adapt to production needs with different curvatures, greatly improving construction efficiency and project quality, and significantly reducing the customization and modification costs of the mold.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 4 The present invention discloses a flexible mold for making an arc-shaped ramp retaining wall, characterized in that it includes: an adjustment mechanism 3, which is electrically connected to a control system 4, and the adjustment end of the adjustment mechanism 3 is provided with a flexible mold 2; The adjustment mechanism 3 includes multiple extension components, which are arranged sequentially at intervals along the length of the arc-shaped ramp retaining wall 1. The extension components are electrically connected to the control system 4. The flexible mold 2 includes a flexible panel 2-4, which is disposed at the extended ends of multiple elongation components, and the arc-shaped ramp retaining wall 1 is located on the top surface of the flexible panel 2-4. The control system 4 controls the extension length of the extension component based on the preset curvature of the arc-shaped ramp retaining wall 1.

[0023] The control system 4 includes a computer, which controls the operation of the elongation component through a control program. The control program is existing technology and will not be described in detail here.

[0024] First, the control system 4 calculates the target extension length of each elongation component based on the preset curvature of the curved ramp retaining wall 1 and issues commands. Next, multiple elongation components, spaced apart along their length, move synchronously or sequentially according to the commands, raising their adjustment ends to different heights. The flexible panel 2-4, laid above the adjustment ends of all the elongation components, naturally sags under its own weight and adheres to these discrete height support points, thus forming a smooth, continuous curved working surface. Finally, construction workers perform rebar tying and concrete pouring operations on this formed curved flexible panel 2-4, thereby creating a curved ramp retaining wall 1 with a curvature perfectly consistent with the design. The technical advantage of this solution lies in the organic combination of the programmable control adjustment mechanism 3 and the flexible panel 2-4, achieving rapid and precise conversion from digital design parameters to a physical curved mold. This allows a single mold to flexibly adapt to the production needs of retaining walls with different curvatures, greatly improving production flexibility, precision, and efficiency, while reducing the cost of traditional custom molds.

[0025] In one alternative, the flexible panel 2-4 can be made of PVC. The flexible panel 2-4 can also be made of flexible reinforced asphalt board.

[0026] In use, the PVC flexible panel 2-4 has good flexibility and extensibility, which can smoothly adapt to the complex curved surface formed by the adjustment mechanism 3 below. At the same time, its surface is smooth and waterproof, which can not only ensure the molding quality of the facing wall 1, but also effectively prevent concrete slurry leakage, facilitate demolding and cleaning, and extend the service life of the mold.

[0027] In one alternative embodiment, the extension assembly includes a storage box 3-1 with an opening at the top. A lifting bar 3-3 is provided inside the storage box 3-1, and a drive assembly for driving the lifting bar 3-3 to rise and fall is provided inside the storage box 3-1. The drive assembly is electrically connected to the control system 4.

[0028] The lifting bar 3-3 is made of ABS hard plastic, but it can also be replaced with stainless steel or other rigid and high-strength materials.

[0029] In use, the control system 4 commands the drive component to operate, smoothly raising and lowering the lifting bar 3-3 located within the storage box 3-1. The storage box 3-1 provides stable support and protection for the entire component, making the movement trajectory of the lifting bar 3-3 precisely controllable. This structure ensures the accuracy of the height of each support point, forming the basis for a precise arc, while also being compact and easy to maintain.

[0030] In one alternative embodiment, the drive assembly includes two drive motors electrically connected to the control system 4. The two drive motors are symmetrically arranged on opposite inner side walls inside the storage box 3-1. The drive motors are located near the top opening of the storage box 3-1. A drive gear 3-2 is coaxially fixed to the output shaft of the drive motor. The drive gear 3-2 meshes with a rack 3-4, which is vertically fixed to the side wall of the lifting bar 3-3.

[0031] The drive motor is a servo motor.

[0032] During operation, the two drive motors receive signals from the control system 4 and rotate synchronously, driving the drive gear 3-2 to rotate. This meshes with the rack 3-4, which is vertically fixed to the side wall of the lifting bar 3-3, thus achieving the vertical movement of the lifting bar 3-3. The symmetrically arranged drive mechanism effectively balances the lateral forces during the lifting process, preventing the lifting bar 3-3 from jamming or tilting, ensuring smooth and reliable transmission and accurate positioning.

[0033] In one alternative, a retaining plate 3-5 is provided on both sides of the lifting bar 3-3. The retaining plate 3-5 extends into the tooth groove of the rack 3-4 and abuts against the top surface of the storage box 3-1.

[0034] Once the lifting bar 3-3 reaches the preset height under the action of the drive assembly, the clamping plate 3-5 is inserted into the tooth groove of the rack 3-4 and abuts against the top surface of the storage box 3-1. This mechanical self-locking method effectively prevents the lifting bar 3-3 from accidentally falling due to the load above or its own weight after the drive motor is powered off, ensuring the stability of the mold's arc shape during concrete pouring and vibration, and enhancing the overall system's operational safety.

[0035] In one alternative embodiment, the bottom surface of the flexible panel 2-4 is provided with two base plates, which are located on opposite sides of the flexible panel 2-4. Each base plate has a groove 2-5 on the side away from each other. A sliding rod is slidably connected in the groove 2-5. A limiting component is detachably connected between the sliding rod and the groove 2-5. The two sliding rods are respectively connected to the left template 2-1 and the right template 2-3. Both the left template 2-1 and the right template 2-3 are in contact with the flexible panel 2-4.

[0036] The left template 2-1 and the right template 2-3 are installed by sliding a rod connected in the slide groove 2-5 and then fixed with a limiting component. This design allows the overall length of the mold to be flexibly and precisely adjusted according to the design length of the retaining wall 1, ensuring that the mold size matches the requirements perfectly. This avoids material waste or unqualified retaining wall size due to length errors and enhances the adaptability of the mold.

[0037] In one alternative scheme, the bottom surface of the flexible panel 2-4 is provided with multiple intermediate modules 2-2, which are arranged sequentially at intervals along the length of the arc-shaped ramp retaining wall 1. The bottom ends of the left template 2-1, the right template 2-3, and the multiple intermediate modules 2-2 are all provided with inserts. The multiple inserts correspond one-to-one with the multiple lifting bars 3-3. The inserts are adapted to the slots at the top of the lifting bars 3-3, and the inserts can be detachably connected to the slots.

[0038] The middle module 2-2, the left template 2-1, and the right template 2-3 are all made of wood and are bonded to the flexible panel 2-4 with waterproof adhesive.

[0039] By setting a left template 2-1, a right template 2-3, and multiple intermediate modules 2-2 on the bottom surface of the flexible panel 2-4, and quickly connecting them to the slots at the top of the lifting bar 3-3 via insert blocks, modular assembly of the bottom support system is achieved. This design allows the mold to quickly adjust the number of modules used according to the length requirements of the facing wall 1, making assembly and disassembly convenient, greatly improving construction efficiency, and facilitating transportation and storage.

[0040] In one alternative embodiment, the left template 2-1 has a plurality of protrusions 2-6 on the side near the flexible panel 2-4, and the plurality of protrusions 2-6 are arranged along the length direction of the left template 2-1. The right template 2-3 has a plurality of grooves 2-7 on the side near the flexible panel 2-4, and the plurality of grooves 2-7 are arranged along the length direction of the right template 2-3.

[0041] The protruding block 2-6 on the left template 2-1 cooperates with the groove 2-7 on the right template 2-3. This design plays a crucial role in the production and use of the retaining wall 1: First, when fabricating a single retaining wall 1, the ends of the prefabricated arc-shaped longitudinal steel bars can accurately engage with the groove 2-7 or abut against the protruding block 2-6, precisely positioning the steel bars and ensuring the forming quality of the steel reinforcement skeleton. Second, and most importantly, when multiple prefabricated arc-shaped retaining walls 1 are transported to the construction site for assembly, the protruding block 2-6 on one retaining wall 1 can naturally embed into the groove 2-7 on the adjacent retaining wall 1, forming a mortise and tenon connection. This connection method not only allows for quick alignment and simplifies construction but also effectively improves the stability and continuity of the overall retaining wall after assembly, enabling each individual wall panel to work together better and enhancing the protection of the ramp roadbed.

[0042] A method for manufacturing an arc-shaped ramp retaining wall, based on a flexible mold for manufacturing the arc-shaped ramp retaining wall, includes the following steps: Based on the required length of the curved ramp retaining wall 1, a flexible panel 2-4 is selected and placed on top of multiple elongation components. The control system 4 controls the extension length of the elongation components based on the preset curvature of the curved ramp retaining wall 1. Reinforcing bars for the retaining wall are set on top of the flexible panel 2-4 and concrete is poured to produce the curved ramp retaining wall 1. After the curved ramp retaining wall 1 has been cured for the set time, the curved ramp retaining wall 1 and the flexible panel 2-4 are separated, and the curved ramp retaining wall 1 is moved to the curing room for curing again for the set time.

[0043] In one alternative, the curing time for the curved ramp retaining wall 1 is 48 hours before separating it from the flexible panels 2-4.

[0044] Detailed working process: The operator first inputs the design parameters of the ramp, namely the curvature and length of the required arc-shaped ramp retaining wall 1, into the control system 4. The control system 4 automatically calculates based on these preset parameters, accurately determining the number of extension components to be arranged along the length of the retaining wall, as well as the target extension height that the lifting bar 3-3 in each extension component needs to achieve, and generates corresponding control commands.

[0045] After the parameters are set, the physical assembly and arc forming stage of the mold begins. Following the prompts from the control system 4, the operator selects the appropriate number of modules for assembly. Specifically, the left template 2-1, right template 2-3, and the required number of intermediate modules 2-2 are inserted sequentially into the slots at the top of the pre-positioned lifting bars 3-3 via their bottom inserts, completing the rapid assembly of the bottom mold. Subsequently, a flexible panel 2-4 of the selected length, such as PVC material, is laid and adhered to the top surface of all modules. At this point, the mold assembly is complete.

[0046] Next comes the crucial power execution and curved surface shaping stage. The control system 4 sends commands to each extension component, and the drive components begin to work. Specifically, the two drive motors located on the inner wall of the storage box 3-1 start synchronously, driving the coaxially fixed drive gear 3-2 to rotate. The drive gear 3-2 meshes with the rack 3-4 vertically fixed to the side wall of the lifting bar 3-3, thereby converting the rotational motion of the motor into the precise vertical lifting motion of the lifting bar 3-3. Each lifting bar 3-3 is raised to its preset different height according to the command. To ensure that the height is stable and accurate during subsequent load-bearing operations, the operator immediately inserts the locking plate 3-5 into the tooth groove of the rack 3-4 on both sides of the lifting bar 3-3, so that its top end abuts against the top surface of the storage box 3-1, realizing mechanical self-locking and effectively preventing accidental fall. As all the lifting bars 3-3 are positioned and locked, the flexible panel 2-4 above them hangs down naturally under the action of gravity, smoothly adhering to these discrete height support points, automatically forming a smooth, continuous, and perfectly designed curved working surface.

[0047] After the arc-shaped mold is formed, the process moves to the precast concrete production stage for the facing wall. Construction workers first prefabricate the arc-shaped reinforcing bars on a rebar processing machine according to the arc shape, and then tie the bars inside the formed mold. The two ends of the longitudinal reinforcing bars are positioned by inserting them into the groove 2-7 of the right template 2-3 and the protrusion 2-6 of the left template 2-1, respectively. Then, the vertical reinforcing bars are tied to form a stable reinforcing steel skeleton. Next, C30 concrete is poured into the mold and thoroughly vibrated to ensure compaction.

[0048] After pouring, the curing and demolding process begins. The concrete is left to cure in the mold for approximately 48 hours until it reaches the early strength required for demolding, at which point the demolding operation is carried out. Operators loosen the limiting components connecting the sliding rod and the slide groove 2-5, and slide the left formwork 2-1 and right formwork 2-3 along the slide groove 2-5 to both sides, thus lifting the formed curved ramp retaining wall 1 away from the mold. Afterwards, retaining wall 1 is sent to a standard curing room for further curing for approximately 14 days.

[0049] Finally, the system is reset for future use. After demolding, the operator removes all the retaining plates 3-5, and the control system 4 instructs the drive motor to reverse, lowering each lifting bar 3-3 back to its initial position in the storage box 3-1. The disassembled modules and flexible panels 2-4 are cleaned and maintained. During disassembly, a hot air blower is used to heat the flexible panels 2-4 from above, melting the waterproof adhesive to detach the flexible panels 2-4 from the modules. The entire mold system can then quickly reset its parameters for use in creating the next retaining wall with a different curvature. Finally, by using the protrusions 2-6 at both ends of each retaining wall 1 and the grooves 2-7 for tenon and mortise joints, a continuous, dense, and highly protective curved retaining wall can be assembled on-site at the ramp.
