Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a formwork structure for a low-height concrete retaining wall of a water conservancy embankment. Background Technology

[0002] For low-height concrete retaining walls in water conservancy embankments, precast concrete formwork or cast-in-place steel formwork is typically used. Factory-prefabricated gravity-type, reinforced concrete, or cantilevered formwork is commonly employed, offering high dimensional accuracy and a smooth surface. Suitable for large-volume concrete structures, it is frequently used for low-height retaining walls, such as riverbank wave walls. Formwork for these walls combines steel flat plates and curved plates, assembled with bolts, resulting in high strength and resistance to deformation even after repeated use. Cast-in-place steel formwork is often used for low-height retaining walls, such as riverbank wave walls and flooded retaining walls, where both wave protection and structural stability must be considered.

[0003] For example, application CN214615404U discloses a formwork structure for a low-height concrete retaining wall in a hydraulic embankment, including multiple first formworks, multiple second formworks, multiple reinforcing members, multiple tie rods, multiple locking elements, and multiple movable tubes. The first and second formworks form a casting cavity. The reinforcing members include first and second reinforcing blocks, with the first reinforcing blocks connected to the multiple first formworks and the second reinforcing blocks connected to the multiple second formworks. The tie rods sequentially pass through the first reinforcing blocks, the first formworks, the second formworks, and the second reinforcing blocks, with one end of the tie rod extending out of the first reinforcing block and the other end extending out of the second reinforcing block. The ends of the tie rods are all connected to the locking elements. The movable tubes are sleeved on the outside of the tie rods and are located between the first and second formworks. This application effectively reduces the waste of tie rods.

[0004] However, in this application, after the concrete of a section of retaining wall reaches the demolding strength, it is impossible to move multiple templates one by one after disassembling the fixed reinforcement parts. This may cause damage and deformation of the templates during the transportation process, resulting in low flatness and poor appearance of the poured concrete wall surface, as well as wasting template installation time and disassembly labor costs.

[0005] In view of this, there is an urgent need for a formwork structure for low-height concrete retaining walls in water conservancy embankments to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a formwork structure for a low-height concrete retaining wall in water conservancy embankments.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A first retaining wall template is attached to a second retaining wall template on one side. A second U-shaped mounting plate is fixedly installed on the outer surface of the first retaining wall template. A limit cylinder is provided on the outer surface of the second U-shaped mounting plate. A first U-shaped mounting plate is fixedly installed on the outer surface of the second retaining wall template. An installation sleeve is provided on the outer surface of the first U-shaped mounting plate. A limit groove is opened on the inner surface of the installation sleeve. A limit post is connected to the inner surface of the limit cylinder. A limit piece is provided on the upper surface of the limit post. An operating handle is fixedly installed on the upper surface of the limit piece.

[0008] Preferably, the lower surface of the second retaining wall formwork is fixedly connected with ground piles, and the inner surface of the second retaining wall formwork is provided with diagonal bracing plates.

[0009] Preferably, a casting cavity is provided on the upper inner surface of the second retaining wall template.

[0010] Preferably, the outer surface of the second retaining wall template is equipped with vertical rods, and the two sides of the vertical rods are provided with connecting seats.

[0011] Preferably, a clearance groove is provided on the inner surface of the center of the vertical rod, a top rod shaft is connected to the inner surface of the clearance groove, and a top rod is installed on the outer surface of the top rod shaft.

[0012] Preferably, a vertical rod pivot is connected to the lower surface of the vertical rod, and a base frame is installed on the outer surface of the vertical rod pivot.

[0013] Preferably, a threaded sleeve shaft is provided on the lower surface of the clearance groove, and a threaded sleeve is connected to the lower surface of the threaded sleeve shaft.

[0014] Preferably, the outer surface of the base frame is provided with a hexagonal head, the inner surface of the hexagonal head is connected with a lead screw, and the lower surface of the base frame is installed with an anchor rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: In this application, by installing a second U-shaped mounting plate on the outer surface of the first retaining wall template and a limiting cylinder on the outer surface of the second retaining wall template, the four retaining wall templates can be connected to form a rectangular groove for pouring concrete. This results in a concrete wall with high flatness and good appearance quality. Installing an installation sleeve on the outer surface of the first U-shaped mounting plate ensures that the lower installation sleeve is aligned vertically with the limiting groove at a uniform installation angle. Installing a limiting post aligns it with the limiting groove and the limiting cylinder, allowing it to be inserted vertically. At this point, the first retaining wall template... The formwork is fixedly connected to the second retaining wall formwork. The installation of limiting plates can prevent the limiting columns from sliding directly out of the limiting cylinder and falling off, which would cause the entire device to disintegrate. The installation of operating handles allows engineers to more easily pull the lower-connected limiting columns out from between the installation sleeve and the limiting cylinder, thus enabling quick disassembly. After the pouring is completed, the limiting columns can be directly pulled out to move the entire formwork to the next section of the retaining wall without disassembling the entire wall formwork for individual transport. This avoids damage and deformation of the formwork, saves labor costs for formwork installation and disassembly, and makes it convenient and economical. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see the appendix Figure 1-5A formwork structure for a low-height concrete retaining wall of a water conservancy embankment, comprising: A formwork structure for a low-height concrete retaining wall of a water conservancy embankment includes: a first retaining wall formwork 1; a second retaining wall formwork 2 connected to one side surface of the first retaining wall formwork 1; a second U-shaped mounting plate 7 fixedly installed on the outer surface of the first retaining wall formwork 1; a limiting cylinder 8 provided on the outer surface of the second U-shaped mounting plate 7; a first U-shaped mounting plate 6 fixedly installed on the outer surface of the second retaining wall formwork 2; an mounting sleeve 10 provided on the outer surface of the first U-shaped mounting plate 6; a limiting groove 9 opened on the inner surface of the mounting sleeve 10; a limiting post 13 connected to the inner surface of the limiting cylinder 8; a limiting piece 12 provided on the upper surface of the limiting post 13; and an operating handle 11 fixedly installed on the upper surface of the limiting piece 12. By installing a second U-shaped mounting plate 7 on the outer surface of the first retaining wall template 1 and a limiting cylinder 8 on the outer surface of the second retaining wall template 2, the four retaining wall templates can be connected to form a rectangular groove for pouring concrete. This results in a concrete wall with high flatness and good appearance quality. Installing an installation sleeve 10 on the outer surface of the first U-shaped mounting plate 6 ensures that the lower installation sleeve 10 is aligned vertically with the limiting groove 9 at a uniform installation angle. Installing a limiting post 13 aligns it with the limiting groove 9 and the limiting cylinder 8, allowing it to be inserted vertically. At this point, the first retaining wall template 1 and... The second retaining wall formwork 2 is fixedly connected. The installation of the limiting plate 12 can prevent the limiting column 13 from sliding directly out of the limiting cylinder 8 and falling off, which would cause the whole device to fall apart. The installation of the operating handle 11 allows the engineers to more easily pull the lower connected limiting column 13 out from between the installation sleeve 10 and the limiting cylinder 8, so that the connection can be quickly dismantled. After the pouring is completed, the limiting column 13 can be pulled out directly to move the formwork to the next section of the retaining wall body. There is no need to disassemble the entire wall formwork and carry it one by one, which avoids damage and deformation of the formwork and saves labor costs for formwork installation and dismantling, making it convenient and economical.

[0020] Specifically, ground piles 3 are fixedly connected to the lower surface of the second retaining wall formwork 2, and diagonal bracing plates 5 are provided on the inner surface of the second retaining wall formwork 2. By installing diagonal bracing plates 5, the pressure caused by impact on the formwork can be reduced, preventing loosening and shaking, and stabilizing the safety of the formwork. Inserting ground piles 3 into the soil can make the upper formwork more stable for installation and use, giving it protection and adaptability.

[0021] Specifically, a pouring cavity 4 is provided on the upper inner surface of the second retaining wall template 2. A rectangular groove formed by multiple templates can serve as the pouring cavity 4, which facilitates the pouring of concrete by engineers, thereby ensuring a relatively smooth and complete concrete wall surface, and giving it connectivity and practicality.

[0022] Specifically, vertical rods 14 are installed on the outer surface of the second retaining wall formwork 2, and connecting seats 15 are provided on both sides of the vertical rods 14. By providing multiple connecting seats 15 on both sides of the vertical rods 14, they can be fixedly installed on the outer surface of the formwork. The installation of the vertical rods 14 and the formwork can form an interconnected support function, giving them both fixation and support.

[0023] Specifically, a clearance groove 16 is provided on the inner surface of the center of the vertical rod 14. A top rod shaft 17 is connected to the inner surface of the clearance groove 16, and a top rod 25 is installed on the outer surface of the top rod shaft 17. By providing a clearance groove 16 on the surface of the vertical rod 14, the top rod 25 has sufficient space to rotate and adjust. The adjustment and movement of the top rod 25 can drive the top rod shaft 17 to rotate and be fixed inside the clearance groove 16, thereby allowing the vertical rod 14 to provide support for the template, making it adjustable and adaptable.

[0024] Specifically, a vertical rod pivot 22 is connected to the lower surface of the vertical rod 14, and a base frame 18 is mounted on the outer surface of the vertical rod pivot 22. By adjusting the movement of the top rod 25, the vertical rod pivot 22 can rotate on the inner surface of the base frame 18, thereby allowing the vertical rod 14 to form connecting support members at different angles. The cooperation between the base frame 18 and the vertical rod 14 ensures the stability of the template, giving it both connectivity and stability.

[0025] Specifically, a threaded sleeve shaft 24 is provided on the lower surface of the clearance groove 16, and a threaded sleeve 23 is connected to the lower surface of the threaded sleeve shaft 24. By installing the threaded sleeve 23 and moving it inside the base frame 18, it can drive the top rod 25 above to move and adjust, thereby allowing the threaded sleeve shaft 24 to rotate to adjust the support angle of the vertical rod 14, making it adaptable and practical.

[0026] Specifically, the outer surface of the base frame 18 is provided with a hexagonal head 21, the inner surface of the hexagonal head 21 is connected to a lead screw 20, and the lower surface of the base frame 18 is installed with an anchor rod 19. By installing the hexagonal head 21, the engineer can rotate the hexagonal head 21 to drive the lead screw 20 connected behind it to rotate, thereby driving the surface threaded sleeve 23 to adjust its position. Installing the anchor rod 19 can make the base frame 18 more firmly inserted into the ground, preventing loosening that would cause the vertical rod 14 to be unstable in supporting the template, thus giving it comprehensiveness and stability.

[0027] The implementation principle of the formwork structure embodiment for a low-height concrete retaining wall of a hydraulic embankment in this application is as follows: By installing a second U-shaped mounting plate 7 on the outer surface of the first retaining wall template 1 and a limiting cylinder 8 on the outer surface of the second retaining wall template 2, the four retaining wall templates can be connected to form a rectangular groove for pouring concrete. This results in a concrete wall with high flatness and good appearance quality. Installing an installation sleeve 10 on the outer surface of the first U-shaped mounting plate 6 ensures that the lower installation sleeve 10 is aligned vertically with the limiting groove 9 at a uniform installation angle. Installing a limiting post 13 aligns it with the limiting groove 9 and the limiting cylinder 8, allowing it to be inserted vertically. At this point, the first retaining wall template 1 and... The second retaining wall formwork 2 is fixedly connected. The installation of the limiting plate 12 can prevent the limiting column 13 from sliding directly out of the limiting cylinder 8 and falling off, which would cause the whole device to fall apart. The installation of the operating handle 11 allows the engineers to more easily pull the lower connected limiting column 13 out from between the installation sleeve 10 and the limiting cylinder 8, so that the connection can be quickly dismantled. After the pouring is completed, the limiting column 13 can be pulled out directly to move the formwork to the next section of the retaining wall body. There is no need to disassemble the entire wall formwork and carry it one by one, which avoids damage and deformation of the formwork and saves labor costs for formwork installation and dismantling, making it convenient and economical.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
