Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline, in particular to an integrally formed socket and spigot hollow 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, the pipe jacking construction method is usually adopted to lay pipelines between drainage wells. Pipe jacking construction is to jack the pipeline unit into the soil in the working pit with the help of jacking equipment. Each pipeline unit usually has a spigot and a socket at both ends. After one pipeline unit is jacked into the soil layer, the spigot of the second pipeline unit is inserted into the socket of the previous pipeline unit, and then continue to jack, and so on to form a pipeline in a cycle.
[0003] In order to facilitate connection and improve the strength of the connection, the aperture of the socket in the pipeline unit is usually set larger than the aperture of the pipe body. However, when laying pipelines with this structure of pipeline unit, a guide hole with an aperture conforming to the aperture of the socket needs to be dug in advance. This will cause the pipe body not to be supported after the pipeline extends into the guide hole because the aperture of the guide hole is larger than the outer diameter of the pipe body. Therefore, the socket and spigot are prone to tilt or sink and cause deviation; when it is put into use later, the socket and spigot are more likely to be affected by ground vibration and break, resulting in pipeline leakage and short pipeline life. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide an integrally formed socket and spigot hollow pipe. After combination, the inner and outer side walls of the pipeline are basically flush at each position, the pipeline is more convenient to lay, and the pipeline is not easy to break and leak.
[0005] In order to solve the above technical problems, the following technical solutions are adopted:
[0006] The integrally formed socket and spigot hollow pipe includes a socket, a spigot and a pipe body. The socket is arranged at the front end of the pipe body, and the spigot is arranged at the rear end of the pipe body. It is characterized in that: it further includes at least one sealing rubber ring. The outer side wall of the socket is flush with the outer side wall of the pipe body, the inner side wall of the spigot is flush with the inner side wall of the pipe body, and the inner side wall of the socket corresponds to the outer side wall of the spigot in position; the inner side wall of the socket is smooth, and at least one annular groove is opened on the outer side wall of the spigot. The number of the annular grooves is the same as that of the sealing rubber rings and they correspond one by one. The sealing rubber rings are arranged in the corresponding annular grooves and the sealing rubber rings protrude from the annular grooves.
[0007] In the above-mentioned integrated socket and plug hollow pipe, by setting the outer side wall of the socket to be flush with the outer side wall of the pipe body and setting the inner side wall of the socket to be flush with the inner side wall of the pipe body, when the pipeline is laid and connected, the socket and the socket are convenient to connect and can be closely combined only by relying on the sealing rubber ring. After the sockets and sockets of adjacent pipeline units are connected, the inner side wall and the outer side wall of the connection part can be basically flush with the inner side wall and the outer side wall of the pipe body respectively. There will be no situation where some positions bulge or sink in the combined pipeline. Therefore, when laid underground, there is no need to dig a deeper pit to bear the connection part of the socket and the socket. The pipeline is more convenient to lay, will not shift, and can also ensure that the pressure on each position of the pipeline is uniform, is not easy to deform and break, and will not leak.
[0008] The above-mentioned inner and outer directions are determined according to the axis of the pipe body. The position close to the axis of the pipe body is the inner, and the position far from the axis of the pipe body is the outer. Usually, the socket and the socket are connected to the front and rear ends of the pipe body by means of fusion welding.
[0009] In a preferred embodiment, the sealing rubber ring includes an inner ring part and an outer ring part. The inner ring part matches the shape of the corresponding annular groove, the inner ring part is located in the corresponding annular groove, and the outer ring part protrudes from the annular groove.
[0010] In a further preferred embodiment, the outer ring part includes at least one elastic ring. The elastic ring is arranged around the outer side wall of the inner ring part, and the elastic ring inclines inward from back to front. In this way, when the socket is inserted into the socket, the elastic ring can be smoothly squeezed and enter the socket, and provides an outward tension force to make the socket tightly inserted into the socket.
[0011] In a further preferred embodiment, the number of the elastic rings is multiple. Usually, the inner ring part and the outer ring part are integrally made of rubber.
[0012] In a preferred embodiment, a first annular slope is provided at the rear end of the socket. The first annular slope inclines outward from back to front. The rear wall of the first annular slope is connected to the pipe body. A second annular slope matching the first annular slope is provided at the rear end of the socket.

The front wall of the third annular slope is connected to the pipe body. A fourth annular slope matching the third annular slope is provided at the front end of the socket. Usually, when the pipeline units are connected, they need to be pushed in with force. By providing the first annular slope, the second annular slope, the third annular slope and the fourth annular slope, it is not easy to cause damage to each other when the socket is pushed into the socket.
[0014] The beneficial effects of the present utility model are as follows: After the combination of this integrated socket and spigot hollow pipe, the inner and outer side walls of the pipe are basically flush at each position, making it more convenient to lay the pipe, and the pipe is not easily broken or leaked.
