Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a tunnel embedded metal conduit connector. Background Technique

[0002] Since there is no effective fixing measure at the interface between the metal pipe and the junction box during the installation of the embedded metal pipe, when pouring the secondary lining concrete after the installation of the embedded metal pipe is completed, the part of the embedded pipe extending into the junction box falls into the concrete under the influence of the concrete pressure and the vibration rod, resulting in the blockage of the embedded pipe. When the embedded pipe is blocked, it is often necessary to re-install the pipeline by grooving. This method not only causes great economic losses, but also affects the appearance quality of the secondary lining concrete and the overall quality of the tunnel. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tunnel embedded metal conduit connector to solve the problems put forward in the above background technique.

[0005] A connector structure is arranged on the connecting pipe. The connector structure is used to connect the connecting pipe and the junction box, and a clamp is arranged on the connector structure;

[0006] The clamp is used to fix the connector structure on the connecting pipe.

[0007] Preferably, the connecting pipe is in a circular tube shape. The connector structure includes a front-end connector and a tail-end connector, and the front-end connector and the tail-end connector are respectively arranged at one end of the connecting pipe.

[0008] Preferably, the number of the clamps is two. The two clamps are respectively sleeved on the front-end connector and the tail-end connector. The front-end connector is used to connect with the junction box, and the tail-end connector seals one end of the connecting pipe.

[0009] Preferably, the junction box is provided with an outward-expanded bayonet, and the outward-expanded bayonet meshes with the front-end connector.

[0010] Compared with the prior art, the beneficial effect of the utility model is: This tunnel embedded metal conduit connector realizes the fixation at the joint of the embedded pipe and the junction box, and the linear deviation of the pipeline, etc., and solves the problems of insufficient fixation, linear deviation of the pipeline, and too long pipeline reservation in the traditional process during pipeline embedding.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 shown, the present invention provides a technical solution: a tunnel pre-embedded metal conduit connector, which is arranged on the connecting pipe 1 and connects the connecting pipe 1 and the junction box, including: a connector structure is arranged on the connecting pipe 1, and the connector structure is used to preliminarily connect the connecting pipe 1 and the junction box, and can seal one end of the connecting pipe 1 to prevent cement from entering the connecting pipe 1 during pouring. The connector structure is used to stably connect the connecting pipe 1 and the junction box. The connector structure is the basic structure of the device. A clamp 11 is arranged on the connector structure. The clamp 11 is a detachable screw connection sleeve ring, which is used to sleeved on the connector structure to fix the connector structure. The clamp 11 is used to fix the connector structure on the connecting pipe 1.

[0020] As Figures 2 - 4As shown, the connecting pipe 1 is circular tubular. The connector structure includes a front-end connector 2 and a tail-end connector 3. The front-end connector 2 and the tail-end connector 3 are respectively arranged at one end of the connecting pipe 1. The front-end connector 2 is a bayonet-type metal pipe, which can be meshed and sealed with the outward-expanded bayonet on the junction box. The number of clamps 11 is two, and the two clamps 11 are respectively sleeved on the front-end connector 2 and the tail-end connector 3, which can effectively fix the connection of the front-end connector 2 and the tail-end connector 3 with the connecting pipe 1 and prevent the front-end connector 2 and the tail-end connector 3 from falling off. The tail-end connector 3 forms a sealing ring by pasting a 5mm-thick rubber sheet inside the connecting pipe 1. The front-end connector 2 is used to connect with the junction box, thereby fixing the connecting pipe 1 on the junction box, and the situation that the part of the embedded pipe extending into the junction box falls into the concrete during the casting of the secondary lining concrete due to the concrete pressure and the working of the vibrating rod as proposed in the background technology, resulting in the blockage of the embedded pipe, will not occur. The tail-end connector 3 seals one end of the connecting pipe 1, which can effectively prevent the concrete from pouring back into the connecting pipe 1 during pouring. The junction box is provided with an outward-expanded bayonet, and the outward-expanded bayonet meshes with the front-end connector 2, which can achieve a sealed connection. While ensuring that the connecting pipe 1 will not fall off, it can also seal the connection part and prevent the intrusion of concrete.

[0021] As described above, in this embodiment, the connecting pipe 1 and the front-end connector 2 are connected by a clamp 11. The front-end connector 2 extends into the connecting pipe 1 from the junction box interface, and the clamp 11 is tightened to complete the installation of the front-end joint. The tail-end connector 3 forms a sealing ring by pasting a 5mm-thick rubber sheet inside the connecting pipe 1. After pasting, it is inserted into the embedded pipe, and the clamp 11 is tightened to complete the installation of the tail-end connection.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
