Description

Technical Field

[0001] This utility model belongs to the field of municipal and water conservancy engineering technology, and specifically relates to a reinforced concrete pipe socket connection structure. Background Technology

[0002] Reinforced concrete pipes are widely used in municipal drainage, water conservancy projects, and other fields due to their high strength and durability. Socket connection is one of the main connection methods, where pipes are joined by the fit between the socket (enlarged end) and the spigot (plain end), relying on sealing materials to prevent leakage. With the development of engineering technology, flexible socket connection structures have gradually become more common, using rubber ring seals. These seals utilize the elastic deformation of rubber to compensate for pipe displacement, improving impermeability and seismic performance. However, existing rubber ring socket structures still have shortcomings, such as the rubber ring's susceptibility to aging, high installation precision requirements, and the potential for seal failure under high water pressure or complex geological conditions. Furthermore, in the socket connection of large-diameter pipes, uneven compression of the rubber ring may lead to localized leakage, affecting the overall reliability of the project.

[0003] Traditional socket connections, in addition to using rubber ring socket structures, also use cement mortar or asphalt hemp fiber filling, which are rigid connections. Although the cement mortar is mostly sealed and smoothed manually during construction, this method is slow and requires high technical skills from the workers, making it impossible to carry out a standardized process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reinforced concrete pipe socket connection structure.

[0005] The technical solution adopted to solve the above technical problems is: a reinforced concrete pipe socket connection structure, including a sealing member, the top of the sealing member is provided with a feed port, the feed port penetrates the sealing member, several closing plates are provided on both the left and right sides of the sealing member, the closing plates are symmetrically arranged, several opening and closing devices are provided between the sealing member and the closing plates, and a smoothing device is provided on the upper part of the interior of the sealing member.

[0006] Furthermore, the sealing member has a socket tube inside, which penetrates the sealing member. The socket tube has a socket on the right side and an insertion port on the left side. The insertion port and the socket are correspondingly arranged, and a rubber ring is provided on the outside of the insertion port.

[0007] Furthermore, magnetic strips are fixedly connected to the sides of the closing plates that are close to each other, a sealing gasket is fixedly connected to the side of the closing plate that is close to the socket tube, the sealing gasket abuts against the socket tube, and a handle is fixedly connected to the side of the closing plate that is away from the sealing element.

[0008] The above method involves placing a rubber ring on the spigot of one socket tube and inserting the spigot and rubber ring into the socket of another socket tube. A sealing material is then placed at the connection between the socket tubes. By pulling the handle, the closing plate is moved with the assistance of an opening and closing device, causing the magnetic strips on the two closing plates to attract each other. The sealing gasket on the inner side of the closing plate contacts the socket tube. Prepared concrete mortar is then poured in through the inlet and smoothed at the socket tube connection using a smoothing device. After the mortar has cured, the closing plate is opened again with the opening and closing device to proceed with the mortar smoothing and curing work at the next connection. This method quickly seals the gaps between socket tubes, is simple and efficient, and facilitates streamlined operations.

[0009] Furthermore, the smoothing device includes a rotating rod, a support block is rotatably connected to the outside of the rotating rod, the support block is fixedly connected to the sealing component, a drive gear is fixedly connected to the right end of the rotating rod, a gear ring is meshed with the outside of the drive gear, the gear ring is rotatably connected to the sealing component, and a smoothing plate is circumferentially fixedly connected to the left side of the gear ring.

[0010] The above method involves manually rotating a rotating rod, which in turn drives a drive gear to rotate. This drive gear rotates a gear ring connected inside the sealing component, which in turn rotates a sizing plate fixed to its left side. The rotation of the sizing plate then smooths the mortar injected into the sealing component at the socket joint, thus sealing the socket.

[0011] Furthermore, the opening and closing device includes a first connecting member, which is fixedly connected to the sealing member. A rotating member is rotatably connected to the side of the first connecting member away from the sealing member. A second connecting member is rotatably connected to the end of the rotating member away from the sealing member. The second connecting member is fixedly connected to the closing plate. Fixing members are fixedly connected to both the front and rear sides of the rotating member. Several springs are fixedly connected to the side of the fixing member near the sealing member. The springs are fixedly connected to the sealing member.

[0012] The above scheme involves moving the closing plate by pulling the handle, which in turn causes the rotating component to rotate and drives the fixing component to rotate. This causes the spring on the fixing component to be in a state of tension on one side and contraction on the other, so that the closing plate seals the gap between the socket tube and the sealing component, preventing mortar from overflowing during grouting. When the closing plate is open, the spring state is the opposite of when it is closed. Opening the closing plate facilitates the movement of the sealing component along the direction of the socket tube, preventing the sealing component from scraping the newly cured mortar and affecting the mortar sealing effect.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model features a sealing component with closing plates on both sides, an opening and closing device between the closing plates and the sealing component, and a smoothing device inside the sealing component. The closing plates seal the gap between the socket tube and the sealing component to prevent mortar from overflowing during grouting, and the smoothing device smooths the mortar at the socket tube connection. This design can quickly seal the gap between the socket tubes, and is simple, efficient, and easy to streamline. Attached Figure Description

The top of the sealing member 1 has an inlet 3 that penetrates the sealing member 1. Several closing plates 4 are provided on both the left and right sides of the sealing member 1, symmetrically arranged. The closing plates 4 are used to seal the gap between the socket pipe 2 and the sealing member 1 to prevent mortar overflow during grouting. Several opening and closing devices 7 are provided between the sealing member 1 and the closing plates 4. Each opening and closing device 7 includes a first connecting member 701, which is fixedly connected to the sealing member 1. A connecting member 701 is rotatably connected to a rotating member 702 on the side away from the sealing member 1. A second connecting member 703 is rotatably connected to the end of the rotating member 702 away from the sealing member 1. The second connecting member 703 is fixedly connected to the closing plate 4. Fixing members 704 are fixedly connected to both the front and rear sides of the rotating member 702. Several springs 705 are fixedly connected to the side of the fixing member 704 near the sealing member 1. The springs 705 are fixedly connected to the sealing member 1. The springs 705 are used to switch the closing plate 4 between open and closed states by changing their own characteristics.

[0024] A smoothing device 6 is provided on the upper part of the interior of the sealing component 1. The smoothing device 6 includes a rotating rod 601. A support block 602 is rotatably connected to the outside of the rotating rod 601. The support block 602 is fixedly connected to the sealing component 1. A drive gear 603 is fixedly connected to the right end of the rotating rod 601. A gear ring 604 meshes with the outside of the drive gear 603. The gear ring 604 is rotatably connected to the sealing component 1. A smearing plate 605 is fixedly connected to the left side of the gear ring 604. The smearing plate 605 is used to smooth the mortar injected in the sealing component 1 at the connection of the socket tube 2, so as to seal the socket tube 2.

[0025] The sealing element 1 has a socket tube 2 inside, which penetrates the sealing element 1. The socket tube 2 has a socket 11 on the right side and a spigot 10 on the left side. The spigot 10 and the socket 11 are arranged correspondingly. The spigot 10 has a rubber ring 12 on the outside. The rubber ring 12 is used to make the socket 11 and the spigot 10 of the socket tube 2 fit together to prevent the liquid inside the tube from leaking out. Magnetic strips 9 are fixedly connected to the sides of the closing plates 4 that are close to each other. Magnetic strips 9 are used to eliminate the gaps between the closing plates 4. A sealing gasket 8 is fixedly connected to the side of the closing plate 4 that is close to the socket tube 2. The sealing gasket 8 abuts against the socket tube 2. A handle 5 is fixedly connected to the side of the closing plate 4 that is away from the sealing element 1.

[0026] The working principle of this embodiment is as follows: When in use, a rubber ring 12 is put on the spigot 10 of the socket tube 2, and the spigot 10 and the rubber ring 12 are inserted into the socket 11 of another socket tube 2. Then, the sealing member 1 is placed at the connection between the socket tubes 2. By pulling the handle 5, the closing plate 4 is moved with the cooperation of the opening and closing device 7, so that the magnetic strips 9 set on the two closing plates 4 attract each other. The sealing gasket 8 set on the inner side of the closing plate 4 abuts against the socket tube 2. Then, the prepared concrete mortar is poured in through the feed port 3, and it is smoothed at the connection of the socket tube 2 by the smoothing device 6. After the mortar is cured, the closing plate 4 is opened with the cooperation of the opening and closing device 7 to carry out the mortar smoothing and curing work at the next connection.

[0027] The working principle of the opening and closing device 7 is as follows: the handle 5 pulls the closing plate 4 to move, and the rotating part 702 rotates, which in turn drives the fixing part 704 to rotate. This causes the spring 705 on the fixing part 704 to be in a state of tension on one side and contraction on the other side, so that the closing plate 4 seals the gap between the socket tube 2 and the sealing part 1, preventing the mortar from overflowing when grouting. When the closing plate 4 is open, the state of the spring 705 is the opposite of when it is closed. When the closing plate 4 is open, it is easy for the sealing part 1 to move along the direction of the socket tube 2, preventing the sealing part 1 from scraping the newly cured mortar and affecting the mortar sealing effect.

[0028] The working principle of the smoothing device 6 is as follows: by manually rotating the rotating rod 601, the rotating rod 601 drives the drive gear 603 to rotate. The drive gear 603 drives the gear ring 604 rotatably connected inside the sealing component 1 to rotate. The rotation of the gear ring 604 drives the smoothing plate 605 fixedly connected to its left side to rotate. The rotation of the smoothing plate 605 smooths the mortar injected in the sealing component 1 at the connection of the socket tube 2, so as to seal the socket tube 2.
