Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline, in particular to an integrally jointed steel strip wound pipe. Background Art
[0002] In recent years, due to the increasing number of urban underground pipelines and rural rainwater and sewage diversion projects, in order to improve the drainage efficiency, a large number of drainage wells need to be added, and the adjacent drainage wells also need to be connected by pipelines. In order to reduce the occupied space during construction and speed up the construction progress, currently, the pipeline jacking construction method is usually adopted to lay pipelines between drainage wells. Pipeline jacking construction means that in a working pit, with the help of jacking equipment, pipeline units are jacked into the soil. Usually, socket and spigot are respectively arranged at both ends of each pipeline unit. After one pipeline unit is jacked into the soil layer, the socket of the second pipeline unit is inserted into the spigot of the previous pipeline unit, and then continue to jack, and so on to form a pipeline in a cycle.
[0003] Due to the connection requirements, the socket and spigot of the pipeline unit are usually stronger in rigidity than the pipe body. Therefore, when the current pipeline unit is produced, the pipe body, socket and spigot need to be manufactured separately first, and then the socket and spigot are respectively welded to both ends of the pipe body. However, since the pipeline is buried underground all year round, the connection between adjacent pipeline units will bear a radial force vertically downward. When discharging sewage, the stress at this position will be further increased. Therefore, the connection between the pipe body and the socket and spigot is usually prone to deformation and fracture, resulting in water leakage, and the service life of the pipeline is not long. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an integrally jointed steel strip wound pipe, in which the connections between the pipe body, socket and spigot are not easily deformed and fractured, and the phenomenon of water leakage will not occur.
[0005] In order to solve the above technical problems, the following technical solutions are adopted:
[0006] The integrally jointed steel strip wound pipe includes a spigot, a socket and a pipe body. The spigot is arranged at the front end of the pipe body, the socket is arranged at the rear end of the pipe body, and the shapes of the spigot and the socket match. It is characterized in that: a reinforcing steel strip is arranged in the pipe body, and the reinforcing steel strip is spirally buried in the outer wall of the pipe body along the length direction of the pipe body, and the longitudinal section of the reinforcing steel strip along the axis is wavy; the spigot and the socket are respectively welded to the front and rear ends of the pipe body.
[0007] In the above integrated joint steel strip wound pipe, by arranging a reinforcing steel strip inside the pipe body, the overall strength of the pipe body is enhanced. Moreover, the socket and the spigot are respectively welded to the front and rear ends of the pipe body, which can improve the integrity of the socket, spigot and pipe body. When the integrated joint steel strip wound pipe is laid in the pipeline later, whether during the connection process or after being buried underground, the connection parts between the pipe body and the spigot and socket are not easily deformed or broken, and there will be no water leakage phenomenon, which can effectively extend the service life of the pipeline.
[0008] In a preferred embodiment, a part of the materials of the socket and the spigot extend and cover the corresponding ports of the pipe body and are welded to the pipe body.
[0009] The above-mentioned method of welding the socket and the spigot to the pipe body respectively can, after the pipe body is extruded, insert the end of the pipe body into the injection mold of the socket and the spigot. When the mold is clamped, the end of the pipe body is also clamped, so that the socket and the spigot can extend and cover the corresponding ports of the pipe body during injection molding and be directly welded to the pipe body.
[0010] In a preferred embodiment, the longitudinal section of the reinforcing steel strip includes a protruding section and two arc sections. The protruding section has a first protrusion protruding outward, and the two arc sections are respectively connected to both ends of the protruding section, and the two arc sections form a second protrusion protruding inward. With this structure, the reinforcing steel strip can form a shape with a longitudinal section similar to a wave shape, so that the reinforcing steel strip also has a certain longitudinal deformation ability and can better resolve the force during the connection of pipeline units.
[0011] In a further preferred embodiment, the number of the reinforcing steel strips is multiple, and the reinforcing steel strips are arranged in sequence along the length direction of the pipe body.
[0012] In a further preferred embodiment, the outer wall of the pipe body has a plurality of third protrusions that match the positions and shapes of the respective first protrusions. The first protrusions of each reinforcing steel strip support the outer wall of the pipe body, thereby forming each third protrusion. The third protrusions can form the reinforcing ribs of the pipe body and further improve the support ability of the integrated joint steel strip wound pipe during burial.
[0013] The beneficial effect of the present utility model is that in this integrated joint steel strip wound pipe, the connection parts between the pipe body and the spigot and socket are not easily deformed or broken, and there will be no water leakage phenomenon. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 is a longitudinal sectional view of the end of the pipe body in the embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:
[0017] As Figure 1-2 shown in the integrated joint steel strip wound pipe, which includes a socket 1, a spigot 2 and a pipe body 3. The socket 1 is arranged at the front end of the pipe body 3, the spigot 2 is arranged at the rear end of the pipe body 3, the shapes of the socket 1 and the spigot 2 are matched, a reinforcing steel strip 4 is arranged in the pipe body 3, and the reinforcing steel strip 4 is spirally embedded in the outer wall of the pipe body 3 along the length direction of the pipe body 3. The longitudinal section of the reinforcing steel strip 4 along the axis is wavy; the socket 1 and the spigot 2 are respectively welded to the front and rear ends of the pipe body 3.
[0018] In the above integrated joint steel strip wound pipe, by arranging the reinforcing steel strip 4 inside the pipe body 3, the overall strength of the pipe body 3 is enhanced, and the socket 1 and the spigot 2 are respectively welded to the front and rear ends of the pipe body 3, which can improve the integrity of the socket 1, the spigot 2 and the pipe body 3. When the integrated joint steel strip wound pipe is laid in the pipeline in the follow-up, whether during the connection process or after being buried underground, the connection parts of the pipe body 3 with the spigot 2 and the socket 1 are not easily deformed and broken, and there will be no water leakage phenomenon, which can effectively extend the service life of the pipeline.
[0019] Part of the materials of the socket 1 and the spigot 2 extend and cover the corresponding ports of the pipe body 3 and are welded to the pipe body 3.
[0020] In the above manner that the socket 1 and the spigot 2 are respectively welded to the pipe body 3, after the pipe body 3 is extruded, the end of the pipe body 3 can be inserted into the injection mold of the socket 1 and the spigot 2. When the mold is clamped, the end of the pipe body 3 is also clamped, so that the socket 1 and the spigot 2 can be directly welded to the pipe body 3 during injection molding.
[0021] The longitudinal section of the reinforcing steel strip 4 includes a protruding section 401 and two arc sections 402. The protruding section 401 has a first protrusion 4011 protruding outward. The two arc sections 402 are respectively connected to the two ends of the protruding section 401, and the two arc sections 402 form a second protrusion 4021 protruding inward. With this structure of the reinforcing steel strip 4, a shape with a longitudinal section similar to a wave shape can be formed, so that the reinforcing steel strip 4 also has a certain longitudinal deformation ability and can better resolve the force during the connection of pipeline units.
[0022] There are multiple third protrusions 301 on the outer wall of the pipe body 3 that are matched with the positions and shapes of the respective first protrusions 4011. The first protrusions 4011 of each reinforcing steel strip 4 support the outer wall of the pipe body 3, thereby forming the respective third protrusions 301. The third protrusions 301 can form the reinforcing ribs of the pipe body 3 and further improve the support ability of the integrated joint steel strip wound pipe during burial.
