Abstract
Description
Technical Field
[0001] This utility model relates to the fields of water conservancy engineering and geotechnical engineering technology, specifically to a prefabricated concrete retaining wall for water conservancy projects with high stability. Background Technology
[0002] In water conservancy projects, concrete retaining walls or retaining slabs are widely used to resist earth pressure and prevent soil erosion. Traditional retaining walls are mostly cast in place, which has disadvantages such as long construction period, great susceptibility to climate, difficulty in quality control, and significant environmental impact.
[0003] Currently, prefabricated retaining walls are beginning to be used. They are usually prefabricated in a factory and then transported to the site for assembly, which improves construction efficiency.
[0004] However, existing prefabricated retaining walls still have some problems:
[0005] Insufficient stability: The connection between the boards is weak, mainly relying on simple mortise and tenon joints or embedded parts. When subjected to greater soil or water pressure, it is prone to misalignment and overturning.
[0006] Poor drainage performance: The drainage system is not tightly integrated with the retaining wall structure, which can easily cause blockages, leading to the accumulation of water pressure behind the wall and increasing the structural load.
[0007] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a prefabricated concrete retaining wall for water conservancy projects with high stability, in order to achieve a more practical value. Utility Model Content
[0008] The purpose of this invention is to provide a prefabricated concrete retaining wall for water conservancy projects with high stability, so as to solve the problems mentioned in the background art.
[0009] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete retaining wall for water conservancy projects with high stability, comprising a rectangular plate body, wherein a left convex side plate and a right convex side plate are respectively provided on the left and right sides of the rectangular plate body, and the adjacent left convex side plates and right convex side plates are fitted together; the top of the rectangular plate body is provided with an upwardly protruding tenon, and the bottom is provided with a tenon groove that matches the shape and size of the tenon;
[0010] Drainage grooves are provided on both sides of the bottom inner side of the rectangular plate.
[0011] When the left and right convex side plates are horizontally fitted together, they form a rectangular groove, and a pre-embedded rod is inserted inside the rectangular groove.
[0012] A drain plate is installed at the bottom of the rectangular plate of the composite structure. A connecting plate is provided at the top of one end of the drain plate, and an insertion pipe that matches the size of the drain groove hole is provided on the outside of the connecting plate.
[0013] Furthermore, sound-insulating foam board may be pasted on the outer side of the rectangular plate.
[0014] Furthermore, the connecting plate is connected by a plug-in connection between the insert pipe, the drainage groove hole and the rectangular plate body.
[0015] Furthermore, the drainage plate is designed with a sloping structure.
[0016] Furthermore, reinforcing ribs can be pre-embedded inside the rectangular plate.
[0017] Furthermore, a water-swellable rubber sealing strip is provided on the contact surface of the tenon and the mortise.
[0018] Furthermore, the tenon is an outwardly protruding trapezoidal protrusion, and the tenon groove is an inwardly recessed trapezoidal groove.
[0019] This utility model provides a prefabricated concrete retaining wall for hydraulic engineering with high stability, which has the following beneficial effects:
[0020] 1. This utility model achieves vertical interlocking through the mortise and tenon structure of the upper and lower layers; and in conjunction with the side plates on both sides, the left and right convex side plates can engage with the pre-embedded rod body when horizontally attached, thereby cooperating with the tenon and mortise groove to form a three-dimensional stable connection system with extremely strong integrity and resistance to shearing and overturning.
[0021] 2. In this utility model, drainage grooves are provided on both sides of the inner side of the rectangular plate, forming an efficient drainage channel that can actively collect and guide water flow, while effectively preventing soil loss and drainage hole blockage, and reducing water pressure behind the wall.
[0022] The rectangular grooves within the rectangular slab can be filled with sandbags or directly poured with concrete grout, depending on the load-bearing requirements, which greatly improves the overturning resistance of the entire retaining slab.
[0023] 3. This utility model features a modular design for the entire retaining plate, making installation as easy as "building blocks," resulting in high construction efficiency. The bottom plate and anchor bolt design allow for flexible installation and adjustment, effectively adapting to various complex foundation conditions. All structures are prefabricated, ensuring quality control. The built-in reinforcing ribs save materials, reduce costs, and extend service life while maintaining strength. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-5This utility model provides a technical solution: a prefabricated concrete retaining plate for water conservancy projects with high stability, including a rectangular plate 1, with a left convex side plate 101 and a right convex side plate 102 respectively provided on the left and right sides of the rectangular plate 1, the adjacent left convex side plates 101 and right convex side plates 102 are fitted together, the top of the rectangular plate 1 is provided with an upward protruding tenon 4, and the bottom is provided with a tenon groove 5 that matches the shape and size of the tenon 4;
[0033] Drainage grooves 103 are provided on both sides of the bottom inner side of the rectangular plate 1;
[0034] When the left convex side plate 101 and the right convex side plate 102 are horizontally fitted together, they form a rectangular groove, and a pre-embedded rod 3 is inserted inside the rectangular groove.
[0035] A drain plate 6 is installed at the bottom of the combined rectangular plate 1. A connecting plate 601 is provided at the top of one end of the drain plate 6. An insert 602 that matches the size of the drain hole 103 is provided on the outside of the connecting plate 601. A sound insulation foam board 2 can be pasted on the outside of the rectangular plate 1. The connecting plate 601 forms a plug-in connection with the rectangular plate 1 through the insert 602, the drain hole 103 and the insert 602. The drain plate 6 adopts a sloping structure. Reinforcing ribs can be pre-embedded inside the rectangular plate 1. A water-swellable rubber sealing strip is provided on the contact surface of the tenon 4 and the tenon groove 5. The tenon 4 is an outwardly protruding trapezoidal protrusion and the tenon groove 5 is an inwardly recessed trapezoidal groove.
[0036] Vertical interlocking is achieved through the mortise and tenon structure of the upper and lower layers; and in conjunction with the side plates on both sides, the left convex side plate 101 and the right convex side plate 102 can engage with the pre-embedded rod body 3 when they are horizontally attached, thereby cooperating with the tenon 4 and the mortise groove 5 to form a three-dimensional stable connection system with extremely strong integrity and resistance to shearing and overturning.
[0037] Drainage grooves 103 are provided on both sides of the inner side of the rectangular plate 1, forming an efficient drainage channel that can actively collect and guide water flow, while effectively preventing soil loss and drainage hole blockage, and reducing water pressure behind the wall.
[0038] The rectangular groove inside the rectangular plate 1 can be filled with sandbags or directly poured with concrete grout according to the load-bearing requirements, which greatly improves the overturning resistance of the entire retaining plate.
[0039] The entire retaining wall features a modular design, making installation as easy as assembling building blocks, resulting in high construction efficiency. The bottom plate and anchor bolt design allow for flexible installation and adjustment, effectively adapting to various complex foundation conditions. All structures are prefabricated, ensuring quality control. The built-in reinforcing ribs save materials, reduce costs, and extend service life while maintaining strength.
[0040] Install the pre-embedded rods 3 at a specified interval, and then stack multiple sets of rectangular plates 1 within the interval between adjacent pre-embedded rods 3, so that the convex side plates on both sides of the rectangular plates 1 cooperate to form a rectangular groove, and make the rectangular groove and the pre-embedded rods 3 fit together in a rectangular fit, thereby limiting and fixing the horizontal position of the rectangular plates 1.
[0041] During the installation of the rectangular plate 1, the tenon 4 at the upper end of the rectangular plate 1 and the adjacent tenon 5 are engaged to form a whole. After assembly, the drain pipe 602 of the drain plate 6 can be inserted at the bottom of the rectangular plate 1, so that the drain pipe 602 and the drain hole 103 are engaged to form an efficient drainage channel. This also avoids water from contacting the base of the wall during drainage, which could cause the bottom to become soft and reduce the water pressure behind the wall.
