Description

A concrete crack repair structure for sewage treatment plant structures Technical Field

[0001] This application relates to the field of concrete repair technology, and in particular to a structure for repairing concrete cracks in sewage treatment plant structures. Background Technology

[0002] Concrete, or simply "concrete," is a type of artificial stone widely used in civil engineering. It is typically made by mixing and pouring a mixture of materials such as cement, water, sand, and stone.

[0003] After concrete is poured, cracks may appear for various reasons. In particular, cracks in the concrete can easily lead to problems such as leakage and corrosion in sewage tanks of sewage treatment plants.

[0004] Chinese patent CN222140805U discloses a structure for preventing cracks on the surface of concrete buildings. It includes a covering trough connected to the surface of the concrete structure layer and set above the crack along its development direction. The crack and the covering trough are filled with repair material. Several traction members are set at intervals in the covering trough and distributed along the development direction of the crack. The concrete structure layer is provided with mounting holes for accommodating fixing rods. A tubular expansion member is sleeved on the outer periphery of the fixing rod. Several expansion joints extending to the bottom of the expansion member are provided axially around its lower part.

[0005] The above-mentioned technology requires drilling holes on both sides of the concrete crack and then pouring expansion joints into the concrete to repair the crack. However, during the drilling process, the concrete may develop secondary cracks at the drilling location due to the pressure during drilling, resulting in poor concrete repair and other shortcomings. Summary of the Invention

[0006] To address the issue of secondary cracks in concrete structures that may result from drilling, this application provides a concrete crack repair structure for sewage treatment plant structures.

[0007] This application provides a technical solution for repairing concrete cracks in sewage treatment plant structures, using the following method:

[0008] A concrete crack repair structure for a sewage treatment plant includes a cast-in-place slab and an anchoring assembly. A rectangular cross-section repair groove is formed at the crack in the concrete. A grouting valve for communicating with the repair groove is provided on the cast-in-place slab. The anchoring assembly is used to fix the cast-in-place slab at the repair groove in the concrete. The anchoring assembly includes an anchor rod and an anchor plate. The cross-section of the anchor plate is arc-shaped. One arc-shaped end of the anchor plate is rotatably mounted on the anchor rod. A torsion spring is provided between the anchor rod and the anchor plate. The outer arc-shaped end of the anchor plate away from its rotation center abuts against the sidewall of the repair groove. A locking element for fixing the cast-in-place slab is provided on the anchor rod.

[0009] By adopting the above technical solution, workers first excavate a repair groove based on the cracks in the concrete using specialized grooving equipment. Then, workers place anchor rods and anchor plates into the repair groove. Under the action of a torsion spring, the end of the anchor plate facing away from the anchor rod will abut against the side wall of the repair groove. Through friction, the end of the anchor plate in contact with the cross-section is prevented from sliding backward. Then, workers fix the pouring slab in the concrete repair groove using locking devices. Finally, repair slurry is injected into the repair groove through a grouting valve. After the injected repair slurry solidifies, workers remove the pouring slab to complete the repair of the concrete cracks. This process does not require drilling, reducing the possibility of secondary cracks in the concrete.

[0010] Optionally, the outer arc of the anchor plate is provided with anti-slip texture.

[0011] By adopting the above technical solution, the friction between the anchor plate and the repair groove is increased, further reducing the possibility of reverse slippage of the anchor plate.

[0012] Optionally, two anchor plates are rotatably mounted on the anchor rod, with the two anchor plates rotating in opposite directions on the anchor rod. A pull rope is provided between the two anchor plates, and the pull rope slides through the anchor rod. A rope-cutting tube is coaxially slidably mounted on the anchor rod, and the rope-cutting tube is used to cut the pull rope.

[0013] By adopting the above technical solution, after the worker places the anchor rod in the repair groove, the worker pushes the rope cutting tube, which cuts the rope. Under the action of the torsion spring restoring deformation force, the two anchor plates rotate in opposite directions. The end of the anchor plate facing away from its rotation center will abut against the side wall of the repair groove, thereby fixing the anchor rod in the concrete repair groove. At the same time, the two anchor plates can adapt to a wider repair groove, making it convenient for workers to operate.

[0014] Optionally, the rope-cutting tube is provided with a plurality of reinforcing rods in the circumferential direction.

[0015] By adopting the above technical solution, on the one hand, the reinforcing rod makes it easier for workers to push the cutting tube in the repair trench; on the other hand, the reinforcing rod can improve the structural strength and repair effect of the solidified repair mud in the repair trench.

[0016] Optionally, the locking element includes a screw rod detachably mounted on the anchor rod, the casting plate is slidably sleeved on the screw rod, and a locking nut is threaded onto the screw rod on the side of the casting plate facing away from the concrete.

[0017] By adopting the above technical solution, after the anchor rod is fixed in the repair groove, the worker installs the screw on the anchor rod, and then puts the casting plate on the screw and fixes the casting plate with the locking nut. This improves the solidification strength of the repair slurry poured in the repair groove and completes the fixing of the casting plate without additional drilling.

[0018] Optionally, a crossbar is provided on the side of the casting slab facing away from the concrete, the screw slides through the crossbar, and the locking nut is used to abut against the crossbar.

[0019] By adopting the above technical solution, the crossbar reduces the possibility of the cast slab bending at the screw, which helps to improve the overall flatness of the concrete surface at the repair groove.

[0020] Optionally, multiple anchor rods are arranged in the repair groove of the concrete, and a connecting bar is provided between two adjacent anchor rods. Several anchor rods are provided on the connecting bar along its length, and all anchor rods are located in the repair groove.

[0021] By adopting the above technical solution, the repair slurry poured into the repair trench solidifies into a whole, which helps to improve the effect of repairing concrete cracks.

[0022] Optionally, a sealing strip is provided on the side of the casting slab closest to the concrete.

[0023] By adopting the above technical solution, the possibility of the repair slurry injected into the repair trench flowing out from the position between the pouring slab and the concrete is reduced.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Workers first excavate a repair groove based on the cracks in the concrete using specialized grooving equipment. Then, workers place anchor rods and anchor plates into the repair groove. Under the action of torsion springs, the end of the anchor plate facing away from the anchor rod will abut against the side wall of the repair groove. Through friction, the end of the anchor plate in contact with the cross-section is prevented from sliding in the opposite direction. Then, workers fix the pouring plate in the concrete repair groove using locking devices. Finally, repair slurry is injected into the repair groove through a grouting valve. After the injected repair slurry solidifies, workers remove the pouring plate to complete the repair work on the concrete cracks.

[0026] 2. After the worker places the anchor rod in the repair groove, the worker pushes the rope cutting tube, which cuts the rope. Under the action of the torsion spring restoring deformation force, the two anchor plates rotate in opposite directions. The end of the anchor plate facing away from its rotation center will abut against the side wall of the repair groove, thereby fixing the anchor rod in the concrete repair groove. At the same time, the two anchor plates can adapt to a wider repair groove, making it easier for workers to operate.

[0027] 3. After the anchor rod is fixed in the repair trench, the worker installs the screw on the anchor rod, then puts the casting plate on the screw and fixes the casting plate with the locking nut. This improves the solidification strength of the repair slurry poured in the repair trench and completes the fixing of the casting plate without additional drilling. Attached Figure Description

[0033] The present application will be further described in detail below with reference to Figures 1-4.

[0034] This application discloses a concrete crack repair structure for sewage treatment plant structures.

[0035] Referring to Figures 1, 2, and 3, a concrete crack repair structure for a sewage treatment plant includes a casting slab 2 and an anchoring component 3. A repair groove 4 with a rectangular cross-section is provided at the crack in the concrete 1. A grouting valve 5 for communicating with the repair groove 4 is arranged on the casting slab 2. A sealing strip 13 is adhered to the side of the casting slab 2 near the concrete 1. The sealing strip 13 is made of flexible rubber material. The anchoring component 3 is used to fix the casting slab 2 to the repair groove 4 in the concrete 1.

[0036] Referring to Figures 2 and 3, the anchoring assembly 3 includes an anchor rod 31 and an anchor plate 32. Two anchor plates 32 are rotatably connected to the anchor rod 31. A torsion spring 33 is arranged between the anchor rod 31 and the anchor plate 32. The cross-section of the anchor plate 32 is arc-shaped. The outer side of the arc of the anchor plate 32 is integrally formed with anti-slip texture 6. One arc end of the anchor plate 32 is rotatably connected to the anchor rod 31. The outer side of the arc of the anchor plate 32 away from its rotation center is used to abut against the side wall of the repair groove 4.

[0037] Referring to Figure 3, two anchor plates 32 are located on both sides of the anchor rod 31 and rotate in opposite directions on the anchor rod 31. A pull rope 7 is tied between the two anchor plates 32. The pull rope 7 slides through the anchor rod 31. The anchor rod 31 has a hole for the pull rope 7 to pass through. A rope cutting tube 8 is coaxially slidably sleeved on the anchor rod 31. Several reinforcing rods 9 are welded circumferentially on the rope cutting tube 8. The rope cutting tube 8 is used to cut the pull rope 7.

[0038] Workers use specialized grooving equipment to create grooves in the cracks of concrete 1, forming a repair groove 4 that communicates with the cracks. Then, after placing the anchor rod 31 in the appropriate position within the repair groove 4, the worker pushes the reinforcing rod 9. The reinforcing rod 9 drives the rope cutting tube 8 to cut the pull rope 7. Under the action of the torsion spring 33 restoring the deformation force, the two anchor plates 32 rotate in opposite directions, and the end of the anchor plate 32 facing away from its rotation center will abut against the side wall of the repair groove 4.

[0039] Referring to Figures 1 and 2, a locking member 34 for fixing the casting plate 2 is arranged on the anchor rod 31. The locking member 34 includes a screw rod 341 bolted to the anchor rod 31. The casting plate 2 is slidably sleeved on the screw rod 341. A crossbar 10 is arranged on the side of the casting plate 2 facing away from the concrete 1. The screw rod 341 slides through the crossbar 10. A locking nut 342 is threaded onto the screw rod 341 on the side of the crossbar 10 facing away from the concrete 1. The locking nut 342 is used to abut against the crossbar 10.

[0040] Referring to Figure 4, multiple anchor rods 31 are arranged in the repair groove 4 of concrete 1. A connecting bar 11 is welded between two adjacent anchor rods 31. A connecting cap 14 is bolted to the anchor rod 31 with the connecting bar 11. The connecting bar 11 is welded to the connecting cap 14. Several anchor rods 12 are welded to the connecting bar 11 along its length. All anchor rods 12 are located in the repair groove 4.

[0041] Workers install multiple anchor rods 31 in the repair groove 4 in the same way, then weld connecting bars 11 between two adjacent anchor rods 31. At the same time, according to the size of the cast slab 2, select and install screw rods 341 on some of the anchor rods 31. Then, workers drill holes in the cast slab 2 according to the positions where the screw rods 341 are installed, and then put the cast slab 2 on the screw rods 341. Finally, workers tighten the locking nut 342 so that the sealing strip 13 is pressed into the concrete 1.

[0042] After the workers prepare the repair slurry, they inject the slurry into the repair tank 4 through the grouting valve 5. After a period of time, the repair slurry solidifies and the pouring slab 2 is removed to complete the repair work on the crack in the concrete 1.

[0043] The implementation principle of a concrete crack repair structure for a sewage treatment plant structure according to an embodiment of this application is as follows: Workers use professional grooving equipment to groove the crack in the concrete 1, thereby forming a repair groove 4 that communicates with the crack. Then, after placing the anchor rod 31 in a suitable position in the repair groove 4, the worker pushes the reinforcing rod 9. The reinforcing rod 9 drives the rope cutting tube 8 to cut the pull rope 7. Under the action of the torsion spring 33 restoring the deformation force, the two anchor plates 32 rotate in opposite directions, and the end of the anchor plate 32 facing away from its rotation center will abut against the side wall of the repair groove 4.

[0044] Workers install multiple anchor rods 31 in the repair groove 4 in the same way, then weld connecting bars 11 between two adjacent anchor rods 31. At the same time, according to the size of the cast slab 2, select and install screw rods 341 on some of the anchor rods 31. Then, workers drill holes in the cast slab 2 according to the positions where the screw rods 341 are installed, and then put the cast slab 2 on the screw rods 341. Finally, workers tighten the locking nut 342 so that the sealing strip 13 is pressed into the concrete 1.

[0045] After the workers prepare the repair slurry, they inject the slurry into the repair tank 4 through the grouting valve 5. After a period of time, the repair slurry solidifies and the pouring slab 2 is removed to complete the repair work on the crack in the concrete 1.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
