Description

Technical Field

[0001] The utility model relates to the technical field of steel-plastic pipes, in particular to a socket-and-spigot type large-diameter steel-plastic pipe. Background Art

[0002] The socket-and-spigot type pipe is made up of many pipe sections. One end of the pipe section is a spigot and the other end is a socket. The diameter of the socket end is partially enlarged, and its inner diameter is larger than the outer diameter of the spigot end. The installation connection is to insert the spigot of the pipe section into the socket of another pipe section. The annular gap between the two ends is filled with interface materials. The interface materials can generally be rubber rings, expansive or asbestos cement. In special cases, lead-coated steel-plastic pipes can also be used.

[0003] At present, when multiple pipelines are being butt-jointed and laid, the large-diameter socket-type steel-plastic pipe is lifted up by a crane and then slowly lowered to align with the pipelines laid in the tunnel. When the two steel-plastic pipes are in the same straight line, the lifted steel-plastic pipe needs to be moved toward the pipeline laid in the tunnel until it is tightly pressed against the pipeline. However, due to its heavy weight, the stability of the steel-plastic pipe is difficult to control when it is lowered by a crane, making it difficult to accurately align the two steel-plastic pipes, resulting in difficulty in butt-jointing and laying. Utility Model Content

[0005] Therefore, the purpose of the utility model is to provide a large-diameter steel-plastic pipe with a socket type, which solves the problem of the current large-diameter steel-plastic pipe with a socket type. When multiple pipes are to be butt-jointed and laid, the steel-plastic pipe is lifted up by a crane and then slowly lowered to be aligned with the pipes laid in the tunnel. When the two steel-plastic pipes are in the same straight line, the lifted steel-plastic pipe needs to be moved toward the pipes laid in the tunnel until it is tightly joined. However, due to its heavy weight, the stability of the steel-plastic pipe is difficult to control when it is lowered by a crane, so that the two steel-plastic pipes are not easy to be accurately aligned, resulting in difficulty in butt-jointing and difficulty in laying.

[0006] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0007] A socket-and-spigot type large-diameter steel-plastic pipe comprises a steel-plastic pipe body, one end of which is provided with a docking ring.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] The utility model provides a socket-type large-diameter steel-plastic pipe. Figure 1-3 It includes a steel-plastic pipe body 1, one end of which is provided with a docking ring, which is smaller than the size of the semicircular ring. Therefore, when the steel-plastic pipe body 1 is docked, it can be directly docked and laid in the up and down directions, thereby increasing the pipeline docking speed and improving the pipeline laying efficiency.

[0028] The docking ring is set as a first arc ring 2, and a first sealing ring 3 is provided at one end of the steel-plastic pipe body 1 close to the first arc ring 2. Specifically, a first annular groove 11 is opened at one end of the steel-plastic pipe body 1 close to the first arc ring 2, and the first sealing ring 3 is embedded in the first annular groove 11; therefore, when the crane lifts up the steel-plastic pipe body 1 to be laid, the steel-plastic pipe body 1 is lowered, as long as the end of the steel-plastic pipe body 1 away from the first arc ring 2 is placed on the first arc ring 2 of the steel-plastic pipe body 1 in the tunnel, the docking can be quickly completed.

[0029] During specific use, after the crane lifts up the steel-plastic pipe body 1 to be laid, it lowers the steel-plastic pipe body 1 so that the end of the steel-plastic pipe body 1 away from the first arc ring 2 is placed on the first arc ring 2 of the steel-plastic pipe body 1 in the tunnel, and the lowered steel-plastic pipe body 1 is driven to press against the steel-plastic pipe body 1 in the tunnel, thereby quickly completing the docking, thereby quickly realizing the laying of the steel-plastic pipe body and improving the efficiency of pipeline laying.

[0030] Embodiment 2:

[0031] See attached Figure 4-5 , which is different from Example 1: a first plug-in block 12 is provided at the bottom of the end of the steel-plastic pipe body 1 away from the first arc ring 2, and a first plug-in groove 21 is provided on the bottom wall of the first arc ring 2. When the two steel-plastic pipe bodies 1 are docked, the first plug-in block 12 is inserted into the first plug-in groove 21, which can effectively ensure that the steel-plastic pipe bodies 1 are tightly docked.

[0032] During specific use, after the crane lifts up the steel-plastic pipe body 1 to be laid, the steel-plastic pipe body 1 is lowered so that the end of the steel-plastic pipe body 1 away from the first arc ring 2 is placed on the first arc ring 2 of the steel-plastic pipe body 1 in the tunnel, and the first plug-in block 12 at the bottom of the lowered steel-plastic pipe body 1 is inserted into the first plug-in groove 21 on the steel-plastic pipe body 1 in the tunnel, so as to quickly complete the docking, thereby quickly realizing the laying of the steel-plastic pipe body and improving the efficiency of pipeline laying.

[0033] Embodiment 3:

Specifically, a second annular groove 13 is opened at the end of the steel-plastic pipe body 1 close to the second arc ring 4, and the second sealing ring 5 is embedded in the second annular groove 13; at this time, when the crane releases and lowers the steel-plastic pipe body 1 to be laid, the end of the released steel-plastic pipe body 1 away from the second arc ring 4 is pressed on the end of the steel-plastic pipe body 1 laid in the tunnel close to the second arc ring 4, and one end of the two second arc rings 4 is pressed together, and the second sealing ring 5 is compressed.

[0035] During actual use, the crane releases and lowers the steel-plastic pipe body 1 to be laid, and the end of the released steel-plastic pipe body 1 away from the second arc ring 4 is pressed on the end of the steel-plastic pipe body 1 laid in the tunnel close to the second arc ring 4, and one end of the two second arc rings 4 are pressed together, and the second sealing ring 5 is tightened.

[0036] Embodiment 4:

[0037] See attached Figure 8 , which is different from Example 1: a second plug-in block 14 is provided at the bottom of the end of the steel-plastic pipe body 1 away from the second arc ring 4, and a second plug-in groove 41 is opened on the bottom wall of the second arc ring 4. When the two steel-plastic pipe bodies 1 are docked, the second plug-in block 14 is inserted into the second plug-in groove 41.

[0038] During specific use, the crane releases and lowers the steel-plastic pipe body 1 to be laid, and the end of the released steel-plastic pipe body 1 away from the second arc ring 4 is pressed on the end of the steel-plastic pipe body 1 laid in the tunnel close to the second arc ring 4, and one end of the two second arc rings 4 is pressed together, and the second sealing ring 5 is tightened, and at the same time, the second plug-in block 14 on the lower steel-plastic pipe body 1 is inserted into the second plug-in groove 41 of the steel-plastic pipe body 1 in the tunnel, thereby ensuring that the two steel-plastic pipe bodies 1 will not rotate relative to each other, thereby improving the docking stability of the steel-plastic pipe body 1, thereby quickly realizing the laying of the steel-plastic pipe body and improving the efficiency of pipeline laying.
