Description

Technical Field

[0001] The invention relates to the technical field of concrete retaining wall construction, and in particular to a concrete retaining wall and a construction method thereof. Background Art

[0002] In water conservancy and hydropower engineering projects, mortar-paved pebbles on the surface of concrete retaining walls are a key decorative and protective structure. It means that pebbles are inlaid on the surface of the wall by mortar-paving on the exterior facade of the concrete retaining wall to form a unique decorative layer. It combines the advantages of concrete and pebbles, making the wall not only beautiful but also durable and resistant to erosion.

[0003] The traditional method of concrete retaining wall surface mortar-laid cobblestone construction is usually to complete the pouring of the concrete retaining wall and remove the formwork, and then according to the appearance requirements, the construction workers will carry out the mortar-laid cobblestone work on the facade of the concrete retaining wall. However, the traditional construction method not only has the problem of asynchronous construction of the concrete retaining wall and the mortar-laid cobblestone, forming a new and old bonding interface between the two, resulting in a weak bonding problem, but also because the thickness of the mortar-laid cobblestone is relatively thin, during installation, the bonding surface between the cobblestone and the concrete retaining wall is limited, which reduces the bonding strength between the two, making the concrete retaining wall and the mortar-laid cobblestones weak. Pebbles are easy to separate, so under the influence of long-term water scouring, weathering erosion and other natural forces, mortar-laid pebbles are prone to cracking and falling off, which not only affects the aesthetics and stability of the overall structure, but also poses a potential threat to the durability and safety of the project. In addition, when the cobblestone masonry reaches a certain height, the construction is difficult, and construction workers need to build scaffolding for high-altitude operations, which poses a safety hazard. Moreover, due to the small thickness of the pebbles, as the masonry height increases, the masonry thickness needs to be increased, resulting in a waste of resources and high construction costs. Summary of the invention

[0004] The purpose of the present invention is to provide a scaffolding support structure for a sloping roof, so as to solve the problems in the prior art of the conventional concrete retaining wall surface mortar-laid cobblestone construction method, such as the cobblestones are not firmly bonded to the wall, are easy to separate and fall off, have great safety hazards, have high construction costs and waste resources.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A concrete retaining wall, comprising:

[0007] A concrete retaining wall body, wherein at least one reinforcing rib is embedded in the concrete retaining wall body to enhance its structural strength;

[0008] A finishing layer, the finishing layer covers the outer facade of the concrete retaining wall body, the finishing layer comprises at least one prefabricated board, each of the prefabricated boards is continuously or discontinuously installed on the outer facade of the concrete retaining wall body from bottom to top along the height direction of the concrete retaining wall body;

[0009] Each of the prefabricated panels comprises a consolidation layer and a plurality of decorative parts, a portion of each decorative part not exceeding half of its height is embedded in the consolidation layer, and the remaining portion of each decorative part can be embedded in the outer facade of the concrete retaining wall body.

[0010] According to the above technical means, by using at least one prefabricated panel as a decorative layer to cover the facade of the concrete retaining wall body, the construction is simple and quick, and the construction period is reduced. Under the bonding effect of the consolidation layer, each decorative part can be prefabricated to form a stable small unit, which improves the construction efficiency and the stability of the connection. At the same time, by embedding at most one-half of each decorative part in the consolidation layer, and the remaining part is embedded in the facade of the concrete retaining wall body, the design not only enhances the bonding strength between the decorative part and the concrete retaining wall body, but also avoids the problems of weak bonding, easy separation and falling off of new and old materials in the traditional mortar-laid cobblestone construction method. Moreover, because the decorative part is at least partially retained in the consolidation layer, it not only ensures its decorative and protective effects, high aesthetics and stability, but also reduces the need for high-altitude operations, reduces construction difficulty and safety hazards, saves construction costs, avoids waste of resources, and complies with the concept of green construction and sustainable development. In addition, by embedding at least one reinforcing rib in the concrete retaining wall body, the structural strength of the concrete retaining wall is significantly enhanced, its ability to resist external loads and natural environmental erosion is improved, and the stability and durability of the concrete retaining wall are ensured.

[0011] Furthermore, the decorative element is a pebble.

[0012] According to the above technical means, the use of pebbles as decorative parts not only has unique aesthetic value and environmental protection characteristics, but also has the advantages of strong durability, convenient construction and high cost-effectiveness. It not only improves the overall performance of concrete retaining walls, but also promotes the green development and sustainable development of the construction industry.

[0013] Furthermore, the consolidation layer is a foam adhesive layer.

[0014] According to the above technical means, a foam adhesive layer is used as a consolidation layer. The foam adhesive not only has good adhesion and sealing properties, and can consolidate multiple pebbles into a small unit, but its lightweight characteristics also reduce the weight of the overall structure, making it easier to transport and install. After the prefabricated panels are installed, the exposed foam adhesive layer can be easily removed to expose the pebbles, ensuring the decorative and protective effects, improving construction efficiency, enhancing the stability of the concrete retaining wall, and maintaining its aesthetics and environmental protection.

[0015] Furthermore, a construction method of the concrete retaining wall as described above comprises the following steps:

[0016] S1, preparing prefabricated panels;

[0017] S2, constructing a concrete retaining wall formwork, and installing at least one reinforcing rib in the concrete retaining wall formwork;

[0018] S3, after the installation of a section of the concrete retaining wall formwork is completed, the consolidation layer of the precast panel is installed on the inner side of the outer facade of the concrete retaining wall formwork from bottom to top along the height direction of the concrete retaining wall formwork;

[0019] S4, pouring concrete;

[0020] S5. After the concrete solidifies, the concrete retaining wall formwork is removed, and a wire brush is used to clean the exposed consolidation layer between the decorative parts.

[0021] According to the above technical means, firstly, by preparing prefabricated panels, pebbles are embedded in the foam rubber layer to form a stable and beautiful prefabricated unit, which is convenient for controlling the quality of the prefabricated panels and improving the construction efficiency; then, reinforcing bars are installed while building the concrete retaining wall formwork, so that during pouring, the reinforcing bars can be firmly combined with the concrete, thereby enhancing the structural strength of the concrete retaining wall, and after the formwork is installed, the consolidation layer of the prefabricated panels is installed on the inner side of the outer facade of the concrete retaining wall formwork in the height direction, thereby realizing the synchronous construction of the pebbles and the concrete retaining wall body, avoiding the problem of weak combination of new and old materials in traditional methods. , and then pour the concrete. Under the squeezing effect of the concrete, the consolidation layer of the precast panel is tightly attached to the inner side of the outer facade of the concrete retaining wall formwork. At the same time, the unembedded part of the pebbles is also completely embedded in the poured concrete. After the concrete is solidified, the formwork is removed, the pebbles are firmly combined with the concrete, and then a wire brush is used to remove the exposed consolidation layer on the surface of the outer facade of the concrete retaining wall to expose the pebbles, ensuring the beauty and cleanliness of the concrete retaining wall. It not only improves the construction efficiency, has a firm combination and good stability, but also reduces the difficulty of construction. Construction workers do not need to build additional scaffolding for high-altitude operations, thus avoiding safety hazards.

[0022] Furthermore, the preparation of the prefabricated board in step S1 includes the following steps:

[0023] S11. Select a flat prefabrication site and lay the prefabricated frame flat on the prefabrication site;

[0024] S12, placing each decoration piece in the prefabricated frame according to the predetermined decoration requirements;

[0025] S13, filling the bottom of the prefabricated frame with a consolidation layer, and the filling height of the consolidation layer shall not exceed one-half of the total height of the decorative element;

[0026] S14. After the consolidation layer is consolidated, the prefabricated frame is removed to obtain the prefabricated panel.

[0027] According to the above technical means, first, a flat prefabrication site is selected and the prefabricated frame is laid flat, which provides a stable foundation for the subsequent placement of decorative parts and filling of consolidation layers, making it easy to control the flatness of the appearance of each decorative part to improve the appearance quality; then, according to the predetermined decoration requirements, each decorative part (such as pebbles) is placed in the prefabricated frame, ensuring that the layout of the decorative parts is beautiful and meets the design requirements; then, the bottom of the prefabricated frame is filled with foam glue as a consolidation layer, and the filling height is controlled within one-half of the total height of the decorative parts, which not only ensures the stability and integrity of each decorative part, but also avoids the influence of the excessive thickness of the consolidation layer on the fit between the decorative parts and the concrete; after the consolidation layer is fully consolidated, the prefabricated frame is removed to obtain the prefabricated board; the prefabricated production of decorative parts is realized, the construction efficiency is improved, and the close combination between the prefabricated board and the concrete retaining wall body is ensured, laying a solid foundation for the subsequent concrete retaining wall construction.

[0028] Furthermore, the concrete retaining wall formwork includes at least three formwork bodies, each of which is installed on the ground and together forms a casting cavity, and two relatively arranged formwork bodies are connected by at least one reinforcing rib, the consolidation layer is installed on the inner side of the formwork body located on the outer surface of the concrete retaining wall, and the concrete is filled in the casting cavity.

[0029] According to the above technical means, a concrete retaining wall formwork is composed of at least three formwork bodies, and each formwork body together forms a casting cavity, which provides space for pouring concrete, and the two relatively arranged formwork bodies are detachably connected by at least one reinforcing rib, which enhances the stability of the formwork body and ensures that the formwork body is not easily deformed and tilted during the pouring process, thereby ensuring the structural strength of the concrete retaining wall. Specifically, when in use, after the installation of each formwork body is completed, the prefabricated parts are first installed on the inner side of the formwork body located on the outer surface of the concrete retaining wall, and then concrete is poured into the casting cavity. The parts of each decorative part (such as pebbles) that are not embedded in the consolidation layer are tightly combined with the concrete. After the concrete solidifies, an integrated concrete retaining wall structure is formed, which not only simplifies the construction process, but also avoids the problem of loose combination of new and old materials in traditional methods, thereby ensuring the beauty and durability of the retaining wall.

[0030] Furthermore, the prefabricated frame is a rectangular frame.

[0031] According to the above technical means, a rectangular frame is used as the prefabricated frame, not only because of its regular shape, easy processing and installation, but also can ensure the accuracy and consistency of the size of the prefabricated board.

[0032] Furthermore, the rectangular frame includes four connecting plates, and two ends of each connecting plate are embedded in sequence.

[0033] According to the above technical means, the rectangular frame is composed of four connecting plates, and the two ends of each connecting plate are embedded in each other, so that the assembly and disassembly of the rectangular frame are simple and quick. When in use, it is only necessary to embed the four connecting plates together in sequence according to a predetermined order and direction to quickly form a complete rectangular frame; and the disassembly process will neither damage the prefabricated panels nor affect the reuse of the connecting plates, thereby improving the preparation efficiency and quality of the prefabricated panels and reducing construction costs.

[0034] Furthermore, each of the connecting plates is a steel plate.

[0035] According to the above technical means, a steel plate is used as a connecting plate. The steel plate has high strength, high toughness and good processing performance, and can ensure the stability and durability of the rectangular frame.

[0036] Furthermore, each of the connecting plates has a thickness of 5 mm and a width of 10 cm.

[0037] According to the above technical means, the thickness of 5mm ensures the strength and stability of the steel plate, so that it can withstand various external forces and pressures in the preparation process of the prefabricated board and is not prone to deformation or damage; at the same time, the width of 10cm provides sufficient connection area, making the connection between the connecting plates tighter and more stable, which not only enhances the overall structural strength of the rectangular frame and ensures its ability to resist deformation and vibration, but also facilitates the standardization and mass production of prefabricated frames, reduces production costs, improves production efficiency, ensures that the quality and size of each prefabricated board are consistent, and provides a good foundation for the subsequent concrete retaining wall construction.

[0038] Beneficial effects achieved by the present invention:

[0039] 1. The present invention adopts at least one prefabricated panel as a decorative layer to cover the outer facade of the concrete retaining wall body, which is not only simple and quick to construct, but also reduces the construction difficulty, improves the construction efficiency, shortens the construction period, reduces the need for high-altitude operations, reduces the construction difficulty and safety hazards, saves construction costs, avoids waste of resources, and complies with the concepts of green construction and sustainable development.

[0040] 2. Under the combined effect of the consolidation layer, each decorative part of the present invention can form a stable prefabricated small unit with good integrity, improved construction efficiency and connection stability, convenient construction, transportation and storage. After the decorative parts are consolidated with the concrete retaining wall body, the surface consolidation layer is removed to expose part of the decorative parts, thereby ensuring its decorative and protective effects, and high aesthetics and stability.

[0041] 3. The present invention embeds each decorative part not exceeding one-half of its height in the consolidation layer, and the remaining part is embedded in the outer facade of the concrete retaining wall body. This not only ensures the stability and integrity of the connection between the decorative parts, but also avoids the influence of the consolidation layer being too thick that affects the embedding of the decorative parts and the concrete, enhances the bonding strength between the decorative parts and the concrete retaining wall body, and avoids the problem of loose bonding, easy separation and falling off of new and old materials in the traditional mortar-laid cobblestone construction method.

[0042] 4.
