Description

Technical Field

[0001] The present invention relates to the technical field of pipelines, in particular to a production process and device for a prestressed carbon fiber plate-wound composite steel cylinder concrete pipe. Background Art

[0002] Prestressed concrete cylinder pipe (PCCP), with its unique prestressed structural design, offers significant economic advantages in large-diameter, medium-to-high-pressure water supply and drainage projects. However, PCCP also has inherent drawbacks. In particular, the lack of prestressing in the mortar protective layer makes the pipe susceptible to microcracks during operation. In corrosive environments, the penetration of corrosive ions can cause corrosion and fracture of the steel wire, further leading to rupture of the steel cylinder and pipe bursts, disrupting pipeline operations and causing significant losses.

[0003] The application of composite materials in piping technology has significantly improved their resistance to internal pressure, while maintaining the same wall thickness and weight. The widespread use of carbon fiber materials in recent years has significantly enhanced their ability to withstand internal pressure. However, carbon fiber materials offer limited anti-leakage capabilities. Therefore, combining existing pipes with composite materials to enhance their resistance to internal pressure has become a pressing technical challenge. Summary of the Invention

The specific steps of preparing the steel cylinder concrete pipe are:

[0010] S1.1 Weld a plurality of studs to the outer wall of the inner steel pipe and the inner wall of the outer steel pipe. The studs are arranged in a plurality of rings spaced apart along the axis of the inner steel pipe, and the studs on the outer wall of the inner steel pipe and the inner wall of the outer steel pipe are staggered with respect to each other.

[0011] S1.2 Pour concrete between the outer wall of the inner steel pipe and the inner wall of the outer steel pipe.

[0012] Optionally, the steel cylinder concrete pipe in step S1 includes an inner steel pipe and an outer steel pipe coaxially sleeved, a concrete layer is filled between the inner steel pipe and the outer steel pipe, a corrugated steel ring is provided on the outer wall of the inner steel pipe and the inner wall of the outer steel pipe, and a plurality of longitudinal ribs are further provided in the concrete layer. The specific steps of preparing the steel cylinder concrete pipe are:

[0013] S1.1 Weld several corrugated steel rings on the outer wall of the inner steel pipe and the inner wall of the outer steel pipe in sequence, and arrange longitudinal reinforcements between the inner and outer corrugated steel rings;

[0014] A plurality of longitudinal ribs are arranged in a circular array along the axis of the inner steel pipe, and the corrugated steel ring on the outer wall of the inner steel pipe and the corrugated steel ring on the inner wall of the outer steel pipe are staggered in the axial direction;

[0015] S1.2 Pour concrete between the outer wall of the inner steel pipe and the inner wall of the outer steel pipe.

[0016] Optionally, the specific steps of winding the carbon fiber plate on the outer wall of the steel cylinder concrete pipe in step S2 are:

[0017] S2.1: Apply glue to the outer wall of the concrete cylinder pipe at the starting end of the winding, and glue the starting end of the carbon fiber plate to the starting end of the winding;

[0018] S2.2: After the carbon fiber sheet is evenly coated with glue from the glue coating box, it is spirally wound along the length of the steel cylinder concrete pipe from the winding starting end;

[0019] S2.3: After the winding is completed, glue is applied to the end of the winding, and the end of the carbon fiber plate is bonded to the end of the winding by glue.

The front end of the carbon fiber plate reel passes through the guide wheel group, the tension stabilizing device and the glue coating box in sequence and is fixed to the winding starting end of the steel cylinder concrete pipe.

[0029] Due to the adoption of the above technical solution, the present invention has the following advantages:

[0030] 1. Compared to prestressed steel wire, carbon fiber sheets are stronger and more corrosion-resistant. Even in corrosive environments for long periods of time, there is no need to worry about corrosion and fracture. Therefore, steel cylinder concrete pipes produced with prestressed carbon fiber sheets have better durability and longer service life. This avoids the risk of pipe bursting due to corrosion and fracture of prestressed steel wire reinforced steel cylinder concrete pipe (PCCP).

[0031] 2. This application uses a double-layer steel pipe with an inner steel pipe and an outer steel pipe, which has better anti-seepage ability than a single steel pipe. Especially under high working pressure, the inner and outer steel pipes have double anti-seepage ability.

[0032] 3. This application uses an inner steel pipe with studs, an outer steel pipe and concrete between them to form a double steel pipe sandwich concrete cylinder. The studs are wrapped under the concrete. The studs can make the inner and outer steel pipes tightly combined with the concrete. Coupled with the prestressed carbon fiber plate wrapped around the outside, such a composite structure forms a better arch structure with better resistance to external pressure. It can adapt to the deeper burial depth of the buried pipeline and adapt to more complex geological conditions.

[0033] 4. This application uses an inner steel pipe with studs, an outer steel pipe and concrete between them to form a double steel tube sandwich concrete cylinder. Unlike traditional prestressed steel cylinder concrete pipe (PCCP), which requires relatively thick concrete, the thickness of the concrete can be greatly reduced, which helps to significantly reduce the weight of the pipeline and facilitates transportation, installation and other operations.

DETAILED DESCRIPTION

[0043] The present invention will be further described below with reference to the accompanying drawings and examples.

[0044] Example 1:

[0045] like Figure 2 and Figure 4 The carbon fiber plate steel cylinder concrete pipe shown includes a steel cylinder concrete pipe 1, a carbon fiber plate 2 is spirally wound on the outer wall of the steel cylinder concrete pipe 1, the outer wall of the carbon fiber plate 2 is wrapped with glass fiber cloth, and the outer wall of the glass fiber cloth is filled with a protective layer 3.

[0046] The steel cylinder concrete pipe 1 includes an inner steel pipe 101 and an outer steel pipe 102 that are coaxially sleeved, and a concrete layer 103 is filled between the inner steel pipe 101 and the outer steel pipe 102. A number of stud modules are arranged at intervals along the axial direction on the outer wall of the inner steel pipe 101 and the inner wall of the outer steel pipe 102. The stud modules include a number of studs 104 arranged in a circular array along the axis of the inner steel pipe 101, and the number of studs 104 are all located in the concrete layer 103.

[0047] like Figure 1 The production process of a prestressed carbon fiber plate wrapped composite steel cylinder concrete pipe shown in the figure has the following specific steps:

[0048] S1: Prepare a concrete cylinder pipe and install connecting components at both ends of the concrete cylinder pipe 1; the specific steps are as follows:

[0049] S1.1 Weld a plurality of studs 104 to the outer wall of the inner steel tube 101 and the inner wall of the outer steel tube 102. The studs 104 are arranged in a plurality of rings spaced apart along the axis of the inner steel tube. The studs 104 on the outer wall of the inner steel tube 101 and the inner wall of the outer steel tube 102 are staggered relative to each other.

[0050] S1.2 pouring a concrete layer 103 between the outer wall of the inner steel pipe 101 and the inner wall of the outer steel pipe 102;

[0051] S1.3 Install connection components at both ends of the steel cylinder concrete pipe 1.

[0052] In this embodiment, the connection assembly is a bolted connection assembly. As one embodiment of the present invention, the bolted connection assembly includes connection flanges 4 provided at both ends of a concrete cylinder pipe 1. The connection flanges 4 are provided with a plurality of bolt holes 401 arranged in an annular array along their axis. When connecting the pipes, the connection flanges 4 of adjacent pipes are connected by bolts.

[0053] S2: Wrap the carbon fiber plate 2 on the outer wall of the steel cylinder concrete pipe 1 using a prestressed winding device; the specific steps are:

[0054] S2.1: Apply glue to the winding starting end on the outer wall of the concrete cylinder pipe 1, and glue the starting end of the carbon fiber plate to the winding starting end;

[0055] S2.2: After the carbon fiber sheet 2 is evenly coated with glue from the glue coating box 10, it is spirally wound along the length of the steel cylinder concrete pipe 1 from the winding starting end;

[0056] S2.3: After the winding is completed, glue is applied to the end of the winding, and the end of the carbon fiber plate is bonded to the end of the winding by glue.

[0057] In this embodiment, the spiral winding angle is greater than 85° and less than 90°, and the spiral winding method can be any of single-layer sparse winding, single-layer tight winding, multi-layer tight winding, and plate-type overlapping winding. The winding method can be selected based on the pipeline's pressure requirements. Single-layer sparse winding refers to single-layer winding with a winding spacing between the side walls of the spiral carbon fiber sheet 2; single-layer tight winding refers to single-layer winding with no winding spacing between the side walls of the spiral carbon fiber sheet 2; and multi-layer tight winding refers to multi-layer winding with no winding spacing between the side walls of the spiral carbon fiber sheet 2. During multi-layer winding, the spiral winding is first wound from the starting end to the end, then from the end to the starting end, repeating these steps until the number of winding layers reaches a predetermined number, after which step S2.3 is performed. Plate-type overlapping winding refers to spirally wound adjacent carbon fiber sheets 2 partially overlapping, with the overlap width between the sheets being between 2 and 3 mm. This overlap width improves the overall sealing of the pipeline and the mechanical properties of the carbon fiber layer, resolving the technical problem of weak compressive strength at the seams between adjacent carbon fiber sheets 2 or carbon fiber filaments during tight winding, leading to easy breakage. In this embodiment, when the glue is completely dry, the pressing plate 5 can be removed or retained.

[0058] S3: Wrapping a filling protective layer on the outside of the wound carbon fiber plate 2, the specific steps are as follows:

[0059] S3.1 Wrap glass fiber cloth around the outer side of the wound carbon fiber plate 2;

[0060] S3.2 Fill and wrap the outside of the glass fiber cloth with a flexible protective layer 3.

[0061] In this embodiment, the flexible protective layer 3 is a filled ordinary foam barrier layer, which effectively prevents the carbon fiber layer from being damaged by collision during transportation or installation, thereby affecting its mechanical properties.

[0062] Example 2:

[0063] like Figure 3 and Figure 5 The carbon fiber plate steel cylinder concrete pipe shown includes a steel cylinder concrete pipe 1, a carbon fiber plate 2 is spirally wound on the outer wall of the steel cylinder concrete pipe 1, and a protective layer 3 is filled on the outer wall of the carbon fiber plate 2;

[0064] The steel cylinder concrete pipe 1 comprises an inner steel pipe 101 and an outer steel pipe 102 which are coaxially sleeved. A concrete layer 103 is filled between the inner steel pipe 101 and the outer steel pipe 102. A plurality of corrugated steel rings 105 are arranged at intervals along the axial direction on the outer wall of the inner steel pipe 101 and the inner wall of the outer steel pipe 102.

[0065] The corrugated steel ring 105 on the outer wall of the inner steel pipe 101 and the corrugated steel ring 105 on the inner wall of the outer steel pipe 102 are staggered in the axial direction. Several of the corrugated steel rings 105 are located in the concrete layer 103. Several longitudinal ribs 106 are also provided in the concrete layer 103. The axis of the longitudinal rib 106 is parallel to the axis of the inner steel pipe 101. Several of the longitudinal ribs 106 are arranged in a circular array along the axis of the inner steel pipe 101.

[0066] like Figure 1 The production process of a prestressed carbon fiber plate wrapped composite steel cylinder concrete pipe shown in the figure has the following specific steps:

[0067] S1: Prepare a concrete cylinder pipe 1 and install connecting components at both ends of the concrete cylinder pipe 1;

[0068] S1.1 Weld a plurality of corrugated steel rings 105 to the outer wall of the inner steel pipe 101 and the inner wall of the outer steel pipe 102 in sequence, and arrange longitudinal ribs 106 interspersed between the inner and outer layers of corrugated steel bars 105;

[0069] A plurality of longitudinal ribs 106 are arranged in a circular array along the axis of the inner steel pipe 101, and the corrugated steel rings 105 on the outer wall of the inner steel pipe 101 and the corrugated steel rings 105 on the inner wall of the outer steel pipe 102 are staggered in the axial direction;

[0070] S1.2 pouring a concrete layer 103 between the outer wall of the inner steel pipe 101 and the inner wall of the outer steel pipe 102;

[0071] S1.3 Install connection components at both ends of the steel cylinder concrete pipe 1.

[0072] In this embodiment, the connection assembly is a spigot-and-socket connection assembly. As one embodiment of the present invention, the spigot-and-socket connection assembly includes a male connector 51 and a female connector 52, respectively disposed at both ends of a concrete cylinder steel pipe 1. An annular sealing ring is sleeved on the outer wall of the male connector 52. When connecting the pipes, the male connector 51 of one pipe is inserted into the female connector 52 of the other pipe.

[0073] S2: Wrapping the carbon fiber sheet 2 on the outer wall of the steel cylinder concrete pipe 1; the specific steps are:

[0074] S2.1: Apply glue to the winding starting end on the outer wall of the concrete cylinder pipe 1, and glue the starting end of the carbon fiber plate to the winding starting end;

[0075] S2.2: After the carbon fiber sheet 2 is evenly coated with glue from the glue coating box 10, it is spirally wound along the length of the steel cylinder concrete pipe 1 from the winding starting end;

[0076] S2.3: After the winding is completed, glue is applied to the end of the winding, and the end of the carbon fiber plate is bonded to the end of the winding by glue.

[0077] In this embodiment, the spiral winding angle is greater than 85° and less than 90°, and the spiral winding method can be any of single-layer sparse winding, single-layer tight winding, multi-layer tight winding, and plate-type overlapping winding. The winding method can be selected based on the pipeline's pressure requirements. Single-layer sparse winding refers to single-layer winding with a winding spacing between the side walls of the spiral carbon fiber sheet 2; single-layer tight winding refers to single-layer winding with no winding spacing between the side walls of the spiral carbon fiber sheet 2; and multi-layer tight winding refers to multi-layer winding with no winding spacing between the side walls of the spiral carbon fiber sheet 2. During multi-layer winding, the spiral winding is first wound from the starting end to the end, then from the end to the starting end, repeating these steps until the number of winding layers reaches a predetermined number, after which step S2.3 is performed. Plate-type overlapping winding refers to spirally wound adjacent carbon fiber sheets 2 partially overlapping, with the overlap width between the sheets being between 2 and 3 mm. This overlap width improves the overall sealing of the pipeline and the mechanical properties of the carbon fiber layer, resolving the technical problem of weak compressive strength at the seams between adjacent carbon fiber sheets 2 or carbon fiber filaments during tight winding, leading to easy breakage. In this embodiment, when the glue is completely dry, the pressing plate 5 can be removed or retained.

[0078] S3: Wrapping a filling protective layer on the outside of the wound carbon fiber plate 2.

[0079] In this embodiment, the protective layer is a flexible foam protective layer 3, which effectively prevents the carbon fiber layer from being damaged by collision during transportation or installation, thereby affecting its mechanical properties.

[0080] This application realizes the production of steel cylinder concrete pipe 1 through welding and concrete pouring, and uses glue to bond and wrap the carbon fiber plate 2 around the outer wall of the steel cylinder concrete pipe 1, thereby realizing a close combination of the steel cylinder concrete pipe and the carbon fiber plate 2. The wrapped carbon fiber plate 2 steel cylinder concrete pipe greatly improves the compressive resistance of the pipeline.

[0081] Example 3:

[0082] like Figure 6 The device for producing a prestressed carbon fiber plate-wound composite steel cylinder concrete pipe is used to implement the process for producing a prestressed carbon fiber plate-wound composite steel cylinder concrete pipe described in Example 1 or 2, and includes a prestressed winding device;

[0083] The prestressed winding device includes a carbon fiber plate reel 7 and a rotating device 6, and the steel cylinder concrete pipe 1 is installed on the rotating device 9;

[0084] A guide wheel group 8, a tension stabilizing device 9 and a glue coating box 10 are sequentially arranged between the carbon fiber plate reel 7 and the rotating device 6. The carbon fiber plate 2 at the front end of the carbon fiber plate reel 7 passes through the guide wheel group 8, the tension stabilizing device 9 and the glue coating box 10 in sequence and is fixed to the winding starting end of the steel cylinder concrete pipe 1.

[0085] In this embodiment, when the carbon fiber plate 2 is wound, the downward traction of the tension stabilizing device 9 and the rotation of the rotating device 6 itself form a counter-tension, forming prestress on the carbon fiber plate 2 and bonding it to the steel cylinder concrete pipe 1 at the same time. The prestress of the carbon fiber plate 2 is preferably controlled to 5% to 60% of the standard value of the tensile strength.

[0086] In this embodiment, when winding the carbon fiber sheet 2, the steel cylinder concrete pipe 1 is mounted on the rotating device 6. The carbon fiber sheet 2 at the front end of the carbon fiber sheet reel 7 is bonded to the steel cylinder concrete pipe 1 using glue. The carbon fiber sheet reel 7 unwinds the sheet at a constant speed, and the rotating device 6 drives the steel cylinder concrete pipe 1 to rotate and move horizontally, completing the winding of the carbon fiber sheet 2. In this embodiment, the adhesive is evenly applied to the carbon fiber sheet 2 using a glue coating box 10.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
