Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology, and in particular to a sealing and water-stopping ring structure for pipe joints in pipe jacking construction. Background Technology

[0002] Pipe jacking is a trenchless pipeline laying technology used in municipal construction. Its advantages include minimal or no impact on the surrounding environment, small construction site size, and low noise. Furthermore, it allows for deep underground operations, an advantage unmatched by open-cut pipe laying. During pipe jacking construction, due to variations in geological conditions, environmental protection requirements for surface buildings, and congestion from existing underground pipelines, the jacking route is often forced to be curved. In such cases, pipe jacking construction guides the centerline of the pipe section along a designed arc, forming a curved pipe jacking system.

[0003] The essence of curved pipe jacking construction is to control the deflection of multiple straight pipe sections at a certain angle at the joints, thereby achieving the curved jacking process of the pipe sections. Compared with straight pipe jacking construction, the curved jacking process of curved pipe jacking places higher performance requirements on the pipe joints, because the overlapping parts of the joints between the preceding and following pipe sections will deflect at a certain angle. Therefore, the waterproof performance of the joints after deflection must be guaranteed. Traditional flat-end pipe joints are prone to lateral slippage and misalignment, causing the pipe section to deviate from the designed pipeline, rendering the sealing measures of the wire mesh concrete lining ineffective. Structures such as spigot and socket pipes are prone to problems such as failure of the seal formed by the socket or the sealing structure using sealing rings when subjected to local stress or relative deflection of the joints. Therefore, it is necessary to further ensure the sealing and water-stopping effect of the pipe joints in the construction of curved pipe jacking.

[0004] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a sealing and water-stopping ring structure for pipe joints in pipe jacking construction. Utility Model Content

[0005] The purpose of this invention is to provide a sealing and water-stopping ring structure for pipe joints in pipe jacking construction that can still ensure the sealing effect between pipe joints even when the joint area undergoes angular deflection.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The present invention relates to a sealing and water-stopping ring structure for pipe joints in pipe jacking construction, comprising a steel socket pipe, wherein the steel socket pipe is provided with a spigot and a socket at both ends, and a steel socket is provided on the socket of the steel socket pipe, and further comprising: an inner pressing buckle structure, wherein the inner pressing buckle structure consists of multiple sets of identical structures and is evenly distributed circumferentially on the inner side of the steel socket.

[0008] The inner clamping structure includes a connecting steel sheet, one end of which is fixedly connected to the inner surface of the steel socket, and the other end is connected to an elastic clamping steel sheet.

[0009] Two sets of elastic rubber rings are connected to the inner side of the steel socket. The two sets of elastic rubber rings are respectively disposed on both sides of the connecting steel sheet. The two ends of the elastic rubber rings are respectively connected to the inner surface of the steel socket and the elastic pressing steel sheet.

[0010] Furthermore, the two adjacent steel socket pipe end faces are pressed against both sides of the connecting steel sheet.

[0011] Furthermore, the elastic clamping steel sheet is used to press against the inner wall of the steel socket pipe.

[0012] Furthermore, the middle part of the elastic clamping steel sheet is fixedly connected to the connecting steel sheet, and the connection part between the elastic clamping steel sheet and the connecting steel sheet has an arc-shaped ridge so that the two ends of the elastic clamping steel sheet are elastically pressed against the inner wall of the steel socket pipe.

[0013] Furthermore, both ends of the elastic clamping steel sheet are provided with curved edges that curve in the opposite direction to the inner wall of the steel socket pipe.

[0014] Furthermore, the connection position between the elastic rubber ring and the inner surface of the steel socket is located close to the position where the connecting steel sheet is located;

[0015] The connection between the elastic rubber ring and the elastic clamping steel sheet is located away from the location of the connecting steel sheet.

[0016] This utility model has the following beneficial effects.

[0017] In this invention, the steel socket and the inner clamping structure form a sealing and water-stopping ring structure. The elastic clamping steel sheet of the sealing and water-stopping ring structure and the steel socket prevent misalignment during pipe section deflection.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, a further detailed description of this utility model will be provided below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1 to 7 As shown;

[0030] This embodiment discloses a sealing and water-stopping ring structure for pipe joints in pipe jacking construction, including a steel socket pipe 1. The steel socket pipe 1 has a spigot and a socket at both ends, which is a commonly used steel socket pipe structure. A steel socket 2 is provided on the socket of the steel socket pipe 1, which is the same as the steel socket 2 in the prior art. The steel socket pipe 1 used to seal the joint also includes an inner pressing buckle structure. The inner pressing buckle structure consists of multiple sets of identical structures that are evenly distributed circumferentially inside the steel socket 2, so that the steel socket 2 is more stably fixed at the joint position of the pipe joint to maintain a good sealing effect.

[0031] The inner clamping structure includes a connecting steel plate 3. One end of the connecting steel plate 3 is fixedly connected to the inner surface of the steel socket 2, and the other end is connected to an elastic clamping steel plate 4. After the pipe joint is connected, the elastic clamping steel plate 4 supported by the connecting steel plate 3 is pressed against the inner wall of the steel socket pipe 1 by its own elasticity to ensure the stability of the steel socket 2 at the pipe joint connection position.

[0032] Two sets of elastic rubber rings 5 ​​are connected to the inner side of the steel socket 2. The two sets of elastic rubber rings 5 ​​are respectively set on both sides of the connecting steel plate 3. The two ends of the elastic rubber rings 5 ​​are respectively connected to the inner surface of the steel socket 2 and the elastic pressing steel plate 4. Based on the steel socket 2 of the conventional steel socket pipe 1, in order to further ensure the sealing effect and improve the sealing and water-stopping effect of the pipe joint in the construction of curved pipe jacking, the pipe joint is further sealed by the inner pressing buckle structure combined with the two sets of elastic rubber rings 5. The two sets of elastic rubber rings 5 ​​seal the position of the pipe joint. When the pipe joint is connected, it is pressed on both sides of the elastic rubber rings 5 ​​to achieve the seal. More importantly, when the pipe joint is deflected at an angle, the elastic rubber rings 5 ​​use their elasticity to always remain pressed on the pipe joint with the deflection of the pipe joint, thus still ensuring the sealing effect between the pipe sections.

[0033] Furthermore, the end faces of the two adjacent steel socket pipes 1 are pressed tightly against both sides of the connecting steel sheet 3.

[0034] Furthermore, the elastic clamping steel sheet 4 is used to press against the inner wall of the steel socket pipe 1.

[0035] The working positions of the connecting steel plate 3 and the elastic clamping steel plate 4 enable the steel socket 2 to maintain stability at the pipe joint mating position by combining the connecting steel plate 3 with the elastic clamping steel plate 4.

[0036] Furthermore, the middle part of the elastic clamping steel sheet 4 is fixedly connected to the connecting steel sheet 3. The connection part between the elastic clamping steel sheet 4 and the connecting steel sheet 3 has an arc-shaped bulge so that the two ends of the elastic clamping steel sheet 4 are elastically pressed against the inner wall of the steel socket pipe 1. The arc-shaped bulge of the elastic clamping steel sheet 4 provides elastic deformation space for the elastic clamping steel sheet 4. Combined with the fact that both ends of the elastic clamping steel sheet 4 are pressed against the inner wall of the steel socket pipe 1, the two ends of the elastic clamping steel sheet 4 are elastically deformed and pressed against the inner wall of the steel socket pipe 1 to form an elastic clamping effect.

[0037] Furthermore, both ends of the elastic clamping steel sheet 4 are provided with curved edges that curve in the opposite direction to the inner wall of the steel socket pipe 1. These curved edges make it easier to insert the pipe joint.

[0038] Furthermore, the connection position between the elastic rubber ring 5 and the inner surface of the steel socket 2 is set close to the location of the connecting steel sheet 3;

[0039] The connection position between the elastic rubber ring 5 and the elastic clamping steel sheet 4 is set away from the location of the connecting steel sheet 3.

[0040] Specifically, the connection positions at both ends of the elastic rubber ring 5 are such that, in its natural state, the elastic rubber ring 5 is tilted relative to the connecting steel plate 3. During the pipe joint assembly process, the pipe joint rests against the elastic rubber ring 5, causing most of the elastic rubber ring 5 to adhere tightly to the connecting steel plate 3, forming a seal between the pipe joint and the joint. Simultaneously, the elastic rubber ring 5 undergoes elastic deformation. Therefore, if an angular deflection occurs at the pipe joint, one side of the pipe joint will separate from the connecting steel plate 3. At this time, the elastic rubber ring 5 uses its elasticity to remain wrapped around or pressed tightly against the pipe joint. (See [reference needed] for this state.) Figure 5 , Figure 6 , Figure 7 This ensures that the pipe sections can still have a good sealing and water-stopping effect even if the joint area of ​​the pipe section is deflected at an angle.

[0041] In the above technical solution, the sealing and water-stopping ring structure for pipe joints in pipe jacking construction provided by this utility model has the following beneficial effects:

[0042] In this invention, the steel socket and the inner clamping structure form a sealing and water-stopping ring structure. The elastic clamping steel sheet of the sealing and water-stopping ring structure and the steel socket prevent misalignment during pipe section deflection. The elastic rubber ring dynamically and effectively seals and stops water leakage between pipe sections, thus ensuring a sealing effect even when angular deflection occurs at the pipe section joint.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
