Description

Technical Field

[0001] This utility model mainly relates to the field of double-wall corrugated pipes, specifically to a splicable double-wall corrugated pipe. Background Technology

[0002] Double-wall corrugated pipes are widely used in municipal drainage, communication cable sheathing, and industrial water supply. Their outer wall has a ring-shaped corrugated structure, while the inner wall is smooth, combining excellent resistance to external pressure with smooth media flow. Traditionally, when extending the laying distance or forming a pipe network, double-wall corrugated pipes typically use a socket connection method, where the spigot end of one pipe is inserted into the socket end of another, and a sealing ring is used for sealing.

[0003] However, while this existing connection method performs well when laying straight pipes, in actual construction, especially in complex terrain conditions, pipelines often need to be laid at a certain angle. Under such bending conditions, the existing technology reveals significant drawbacks: the connection between the two corrugated pipes at the bend is subjected to complex and uneven forces. Axial tension and compression: When bending, the outer part of the pipe is stretched and the inner part is compressed. This uneven axial force will try to pull the socket apart or cause the spigot to shift within the socket.

[0004] Radial shear force: The bending deformation of the pipe will generate radial shear stress on the connection interface, attempting to cause the spigot end and the socket end to misalign and deform.

[0005] Torsional load: When there is non-planar bending or uneven terrain settlement, the connection may also be subjected to torsional load, which may further damage the concentricity and stability of the connection.

[0006] Under the combined effect of these uneven forces, traditional socket joints are prone to the following problems: First, the sealing ring may experience uneven compression or localized relaxation, leading to a decrease in its sealing performance; second, the spigot may be partially pulled out of the socket or undergo a slight angular deflection. Ultimately, this manifests as gaps appearing at the connection point.

[0007] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is: a splicable double-wall corrugated pipe, comprising a corrugated pipe structure, wherein connecting structures are provided at both ends of the corrugated pipe structure; A corrugated pipe structure includes a corrugated pipe body, which is arc-shaped. A partition is provided inside the corrugated pipe body, and the number of partitions is set to multiple. The multiple partitions are evenly distributed inside the corrugated pipe body, and the outer wall of the partition is provided with reinforcing ribs.

[0010] Furthermore, mounting flanges are provided at both ends of the bellows body, and the outer wall of the mounting flange is provided with a sliding groove.

[0014] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This invention pre-produces a bellows structure with the required curvature of two double-walled bellows, and connects the bellows structure to the two double-walled bellows. The pre-set arc-shaped bellows structure can reduce the repositioning of the bellows structure during installation, thereby reducing radial shear force, torsional load, and axial tensile and compressive force.

[0021] See attached document Figure 1-3 A splicable double-wall corrugated pipe includes a corrugated pipe structure 1, wherein the two ends of the corrugated pipe structure 1 are provided with connecting structures 2. A bellows structure 1 includes a bellows body 101, which is arc-shaped. Multiple partitions 102 are evenly spaced inside the bellows body 101. Reinforcing ribs 103 are provided on the outer walls of the partitions 102. Mounting flanges 104 are provided at both ends of the bellows body 101. Multiple sliding grooves 105 are formed on the outer walls of the mounting flanges 104, arranged in a circular array on the outer walls. Limiting grooves 106 are formed on both sides of the inner walls of the sliding grooves 105. The interior of 04 has a first insertion hole 107. The bellows body 101 is pre-produced. According to the arrangement and direction of the initially designed double-walled bellows, an arc-shaped bellows body 101 is produced between the double-walled bellows that need to be bent, fixing the shape of the bellows body 101. This avoids the bellows body 101 from generating large radial shear force, torsional load, and axial tensile and compressive force when directly bending it. At the same time, after the liquid enters the interior of the bellows body 101, the liquid is separated by the baffle 102, allowing the liquid to flow between the two baffles 102 or between the bellows body 101 and the baffle 102, preventing the liquid from scouring the outside of the bellows body 101 for a long time.

[0022] Furthermore, the connecting structure 2 includes a sliding hole 201 and a lifting plate 204. The sliding hole 201 is slidably connected to the inner wall of the sliding groove 105. Limiting strips 202 are provided on both sides of the sliding hole 201, and the limiting strips 202 are slidably connected to the inner wall of the limiting groove 106. A support strip 203 is provided at the top of one end of the sliding hole 201. A positioning groove 205 is provided in the middle of the lifting plate 204, and the positioning groove 205 is slidably connected to the outer wall of the support strip 203. Second insertion holes 206 are provided on both sides of the inner wall of the lifting plate 204. When it is necessary to connect the corrugated pipe body 101 with the double-wall corrugated pipe, the connection of the double-wall corrugated pipe is... The flange is aligned with the mounting flange 104, and a sealing ring is installed between them. Then, the sliding hole 201 is pushed inward, and the sliding hole 201 causes the limiting strip 202 to slide on the inner wall of the limiting groove 106. Then, the lifting plate 204 moves to the top of the connecting flange of the double-wall corrugated pipe, and then the lifting plate 204 is pushed downward, so that the lifting plate 204 slides downward on the outer wall of the support strip 203. Then, the second insertion hole 206 is aligned with the hole inside the double-wall corrugated pipe and the first insertion hole 107. Then, the bolt is inserted into the lifting plate 204 and the first insertion hole 107 for fastening, thereby connecting the double-glass corrugated pipe with the corrugated pipe body 101, thus realizing the splicing function.

[0023] Design and planning phase The curvature of the arc-shaped corrugated pipe structure 1 is determined based on the actual route and bending angle requirements of the pipeline.

[0024] Pre-produce the curved corrugated pipe structure to ensure that its curvature matches the bending requirements on site.

[0025] Manufacturing stage A corrugated pipe body 101 is manufactured, and multiple equally spaced partitions 102 are arranged inside.

[0026] Reinforcing ribs 103 are provided on the outer wall of each partition to enhance structural strength.

[0027] Mounting flanges 104 are provided at both ends of the bellows body. The outer wall of the flange has an annular array of sliding grooves 105 and limiting grooves 106, and the inner wall has a first insertion hole 107.

[0028] On-site installation preparation Prepare connection structure 2, including sliding hole 201, limiting strip 202, support strip 203, lifting plate 204, positioning groove 205 and second insertion hole 206.

[0029] Prepare auxiliary connecting parts such as sealing rings and bolts.

[0030] Installation and connection process Place the arc-shaped corrugated pipe structure 1 at the location where bending is required.

[0031] Align the connecting flange of the double-wall corrugated pipe with the mounting flange 104, and place the sealing ring in the middle.

[0032] The sliding hole 201 of the connecting structure 2 is pushed into the sliding groove 105, and the limiting strip 202 slides along the limiting groove 106 to achieve initial positioning.

[0033] Push the lifting plate 204 to slide downward along the support bar 203 so that the second insertion hole 206 is aligned with the first insertion hole 107 and the hole on the double-walled corrugated pipe.

[0034] Insert the bolts and tighten them to complete the connection.

[0035] Use and Maintenance When the liquid flows through the curved section, it is diverted by the baffle to avoid unilateral scouring.

[0036] Regularly check the sealing of connections and the integrity of the structure.

[0037] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent.
