Description

Technical Field

[0001] The utility model relates to the field of pipeline repair, in particular to an inner lining structure for repairing a drainage pipeline based on reinforced concrete. Background Art

[0002] Pipeline is one of the main devices for transporting various fluids and other substances. Therefore, it is widely used in various fields of people's life and production. The pipes used are different for different usage scenarios. For example, the drainage pipes used in some large-scale projects are made of reinforced concrete. However, during the application process, due to problems such as service life, the pipes will be damaged to a certain extent. In order to ensure subsequent use, such situations are generally repaired.

[0003] At present, there are many ways to repair reinforced concrete drainage pipes. For large pipes such as reinforced concrete, the inner lining is mostly used for repair to ensure the overall strength after repair. Due to the uncertainty of the damaged length of the pipe during the repair process, some groups of liners will be welded on site to form a longer lining part. Since the damaged part is completely covered, the assembly by welding requires the arrangement of welding machines and other equipment on site, and the welding operation takes a long time, which causes a large workload for the staff and easily slows down the repair progress.

[0013] As a further solution of the utility model: the central axis of the double-headed screw coincides with the central axis of the nut, and the double-headed screw and the nut are threadedly connected.

[0014] As a further solution of the utility model: the sliding structure includes a movable part, the movable part passes through the side of the installation groove close to the through hole, and the movable part extends to the inside of the through hole, an elastic part is connected between the movable part and the annular block, a covering part is installed on the side of the movable part close to the through hole, and a pressing ring is installed on the side of the cover close to the double-headed screw.

[0030] See also Figure 1-Figure 4 As shown, a lining structure for repairing a reinforced concrete drainage pipe comprises: a plurality of groups of annular lining steel plate bodies 2 arranged in a reinforced concrete drainage pipe body 1, a pouring port 3 is opened on one side of the top of the outer wall of the annular lining steel plate body 2, the annular lining steel plate body 2 is a steel sheet, and when in use, the plurality of groups of annular lining steel plate bodies 2 need to completely cover the damaged part inside the reinforced concrete drainage pipe body 1;

[0031] An extrusion mechanism for positioning the annular lining steel plate body 2 is provided, and the extrusion mechanism includes a plurality of fixed plates 4, and the fixed plates 4 are evenly installed on the outside of the annular lining steel plate body 2, and an extrusion screw body 5 is penetrated through the top of the fixed plate 4, and the extrusion screw body 5 penetrates the annular lining steel plate body 2, and the central axis of the extrusion screw body 5 is perpendicular to the central axis of the annular lining steel plate body 2, and the extrusion screw body 5 is threadedly connected to the fixed plate 4.

[0032] After the annular lining steel plate body 2 is moved to the designated position to cover the damaged part inside the reinforced concrete drainage pipe body 1, the extrusion screw body 5 can be twisted so that the end of the extrusion screw body 5 away from the annular lining steel plate body 2 is fully fitted with the inner wall of the reinforced concrete drainage pipe body 1 to generate sufficient pre-tightening force, so that the annular lining steel plate body 2 can be positioned at the designated position, and an elastic part can be further provided at the end of the extrusion screw body 5 to ensure that it has sufficient pre-tightening force.

[0033] Annular blocks 6 are installed on the outer sides of the annular lining steel plate main body 2 near both ends, and through holes 7 are evenly opened on the outer sides of the annular lining steel plate main body 2 near both ends. Receiving grooves 8 are evenly opened on the inner side walls of the annular blocks 6, and the receiving grooves 8 are connected with the through holes 7. A double-headed screw 9 passes through one side of the interior of the receiving groove 8, and nuts 10 are sleeved on the outer sides of the double-headed screw 9 near both ends.

[0034] After the staff has assembled and positioned the multiple groups of annular lining steel plate bodies 2, they can insert the double-headed screw rod 9 into the through holes 7 on the two adjacent groups of annular blocks 6, and limit the two ends of the double-headed screw rod 9 through two groups of nuts 10, so that the multiple groups of annular lining steel plate bodies 2 are limited and fixed together, and then resin or concrete or other adhesives are poured between each group of annular lining steel plate bodies 2 and the reinforced concrete drainage pipe body 1 through the pouring port 3 for repair;

[0035] See also Figure 1 , Figure 2 and Figure 4 As shown, a mounting groove 11 is evenly provided at one end of the annular block 6 away from the through hole 7, and a sliding structure for protecting the nut 10 is arranged inside the mounting groove 11, and the sliding structure includes a movable part 12, the movable part 12 passes through the side of the mounting groove 11 close to the through hole 7, and the movable part 12 extends to the inside of the through hole 7, an elastic part 13 is connected between the movable part 12 and the annular block 6, a covering part 14 is installed on the side of the movable part 12 close to the through hole 7, and a pressing ring 15 is installed on the side of the covering part 14 close to the double-headed screw 9, the cross-sectional shape of the movable part 12 is "T" shaped, and the movable part 12 is slidably connected to the annular block 6.

[0036] After the staff pours the filler between the annular lining steel plate main body 2 and the reinforced concrete drainage pipe main body 1, the filler will squeeze the movable part 12 after filling the space between the annular lining steel plate main body 2 and the reinforced concrete drainage pipe main body 1, thereby driving the covering part 14 to cover the outside of the nut 10 and at the same time fit and extrude the stud screw 9. The further pressing ring 15 can fit and extrude the nut 10, thereby fully protecting the nut 10 and the stud screw 9, and at the same time limiting the loosening direction, thereby ensuring the stability of the connection.

[0037] The device is suitable for various large concrete pipes that can be entered by personnel. Multiple groups of annular lining steel plate bodies 2 are moved into the reinforced concrete drainage pipe body 1 and assembled until the damaged part of the reinforced concrete drainage pipe body 1 can be completely covered. Then, each group of extrusion screw bodies 5 are respectively screwed until the extrusion screw bodies 5 are fully fitted and extruded with the inner wall of the reinforced concrete drainage pipe body 1 and sufficient pre-tightening force is generated, thereby fixing the annular lining steel plate body 2 in the adjusted position.

[0038] Then, multiple groups of double-headed screws 9 are respectively inserted into the corresponding holes inside the through holes 7 on the two adjacent groups of annular blocks 6, and two groups of nuts 10 are respectively screwed to the two ends of the corresponding double-headed screws 9, so as to connect and fix the multiple groups of annular lining steel plate bodies 2.

When the annular lining steel plate main bodies 2 and reinforced concrete drainage pipe main bodies 1 are filled with fillers, the fillers further squeeze the movable parts 12, so that the movable parts 12 drive the covering parts 14 to cover the corresponding stud screws 9 and nuts 10. At the same time, the covering parts 14 complete the fitting and extrusion of the stud screws 9, and the pressing rings 15 further complete the fitting and extrusion of the nuts 10, thereby limiting the loosening of the stud screws 9 and nuts 10 and protecting them at the same time. Finally, the pouring ports 3 can be closed after the fillers are completely dry.
