[0002] Concrete socket pipes are mostly used in municipal pipeline projects, mainly for transporting industrial and domestic water supply, sewage, and rainwater discharge. The water supply and drainage pipeline project is an important part of the project drainage system. Among them, concrete socket pipes are widely used in construction because of their mature construction technology, low price, and convenient construction. Socket pipes are mainly classified according to the diameter of the pipe. One end of a pipe is a enlarged part as the socket, and the other end is the spigot. The spigot of one pipe is inserted into the socket of another pipe to complete the installation of the pipe. However, in this construction process, the sealing at the socket and spigot positions is not tight, and the space at the support angle position under the socket and spigot is limited and it is difficult to carry out secondary sealing. The socket and spigot often have poor sealing effects, which are prone to rainwater and sewage leakage, polluting the environment. Seriously, it will also cause the pipe foundation to be soaked and scoured, resulting in ground settlement and collapse, posing a safety hazard. Content of the Utility Model

[0027] The following further describes the present utility model in detail with reference to embodiments.
[0028] Specific embodiments of the multi-channel leak-proof structure concrete socket pipe provided by the present utility model:
[0029] Please refer to Figures 1-4 , a multi-channel leak-proof structure concrete socket pipe, comprising a socket end 1 and a spigot end 2, the socket end 1 is inserted into the inner side of the spigot end 2 of an adjacent concrete socket pipe; the concrete socket pipe is formed by a mold; the socket end 1 and the spigot end 2 are the two ends of the socket pipe, and one end of the socket pipe has an enlarged portion, and this end is the spigot end 2; during construction, the socket pipes are connected end to end and inserted.
[0030] In this embodiment, the outer side of the port part of the socket end 1 has a first annular groove 101, and the inner side of the port part of the socket end 2 has a second annular groove 201. The inner diameter of the outer circumferential surface of the second annular groove 201 is slightly larger than the outer diameter of the socket end 1 of the socket and spigot pipe at the non-first-annular-groove 101 position, so that the socket end 1 can be inserted into the second annular groove 201. The axial span of the first annular groove 101 is smaller than the axial span of the second annular groove 201, so that the first annular groove 101 can completely extend into the second annular groove 201.
[0031] A first sealing ring 3 and a second sealing ring 4 are arranged at intervals between the outer ring side of the socket end 1 and the inner side of the socket end 2. The inner side of the first sealing ring 3 is in contact with both the outer ring side of the socket end 1 and the outer edge of the end face of the socket end 1; in this embodiment, the cross-sectional shape of the first sealing ring 3 is V-shaped, and the two annular side faces on the inner side of the V-shaped opening of the first sealing ring 3 are respectively in contact with the outer ring side of the socket end 1 and the outer edge of the end face of the socket end 1.
[0032] The cross-sectional shape of the second sealing ring 4 is triangular. A shoulder for limiting the second sealing ring 4 is arranged on the outer ring side of the socket end 1, and this shoulder is formed by the first annular groove 101.
[0033] The outer ring side of the socket end 1 and the inner ring side of the socket end 2 squeeze the first sealing ring 3 and the second sealing ring 4 to achieve ring-side sealing; at the same time, the first sealing ring 3 and the second sealing ring 4 can also play a part in preventing the pipeline from falling off and shifting.
[0034] A third sealing ring 7 is connected to the inner ring side of the first sealing ring 3. In this embodiment, the third sealing ring 7 and the first sealing ring 3 are integrally connected; the third sealing ring 7 is located between the end face of the socket end 1 and the socket end 2. During the plug-in installation, the socket end 1 enters the socket end 2, and the end face of the socket end 1 and the side ring surface of the second annular groove 201 of the socket end 2 squeeze the third sealing ring 7, that is, the plugging is in place, and the third sealing ring 7 realizes the sealing at the end face of the socket end 1. The third sealing ring 7 can fill the gaps formed due to pipeline structure size errors and improper installation.
[0035] In this embodiment, the first sealing ring 3, the second sealing ring 4 and the third sealing ring 7 are all made of rubber sealing rings. The cross-section of the third sealing ring 7 can be circular or oval. Before installation, first sleeved the sealing ring on the corresponding position of the socket end 1, and then carry out the plug-in installation.
[0036] The socket end 1, the socket end 2, the first sealing ring 3 and the second sealing ring 4 enclose an annular cavity 5 for accommodating the filler.
[0037] In this embodiment, the filler is cement slurry, which is not shown in the figure. A number of filling holes 6 corresponding to the cavities 5 are provided on the socket end 2. The filling holes 6 are evenly distributed in a circumferential manner. In this embodiment, the number of filling holes 6 is four, which are respectively located in the four directions of up, down, left and right. One filling hole 6 at the lower part serves as a grouting hole; three filling holes 6 at the upper part serve as overflow holes. The overflow of slurry through the overflow holes can be used to judge whether the cavities 5 are filled densely. In some other embodiments, the filler can be foam, such as polyurethane foam.
[0038] Compared with the traditional socket pipe, the socket pipe of this embodiment has multiple leak-proof structures, which solves the disadvantages of the traditional socket pipe such as poor sealing and improper socketing, and at the same time can also reduce the workload of secondary pipe orifice plugging and improve work efficiency.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
