[0002] With the continuous expansion of urban scale and the continuous improvement of environmental protection requirements, the construction of urban pipelines has increasingly higher requirements for the sealing of concrete pipe interfaces. Among them, concrete pipe interfaces with good corrosion resistance, pressure resistance and water-stopping effects are very necessary for current pipeline construction.

[0003] The joints of traditional concrete pipes are usually made of carbon steel, which has poor corrosion resistance and the cost of the carbon steel plate itself is also relatively high. In addition, the current common concrete pipe waterproofing structure has a waterproof gasket or a water-stopping rubber strip on the inner side of the plug-in joint. However, due to problems with the interface structure itself, the joints are prone to low fit or interface misalignment, and the sealing gasket may also be uneven or partially peeled off, resulting in poor water-stopping effect.

[0008] Preferably, a plurality of threaded steel nails are radially arranged on the left half of the plastic sleeve, and the threaded ends of the threaded steel nails pass through the plastic sleeve and are buried in the concrete pipe.

[0009] Preferably, at least two water stop rings are arranged on the inner wall of the left half of the plastic sleeve, the water stop ring is buried in the concrete pipe, the cross section of the water stop ring is a T-shaped structure, and the water stop ring and the plastic sleeve are arranged as an integrated structure.

[0011] Preferably, the modified rubber block is made of a rubber material that is in a clay-like state and has high elasticity, high compressibility and high adhesion.

[0012] The utility model provides a concrete pipe interface connection structure. It has the following beneficial effects: a plastic sleeve is used to replace the carbon steel sleeve structure in the prior art, thereby solving the problem of carbon steel corrosion and reducing the cost of the concrete pipe interface connection structure. And by setting a lateral modified rubber sealing ring, when two concrete pipes are butt-jointed, the lateral modified rubber sealing ring can be squeezed, so that the sealing and water-stopping effect of the interface position of the two concrete pipes can be effectively enhanced by the lateral modified rubber sealing ring.

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0019] Embodiment 1, as Figure 1-2 As shown, a concrete pipe interface connection structure includes a plastic sleeve 1, the left half of the inner ring wall of the plastic sleeve 1 is fixedly sleeved on the right end surface of the concrete pipe 2, specifically, a step recess can be provided on the outer surface of the right end of the concrete pipe 2, and the left half of the plastic sleeve 1 is embedded in the step recess; the right half of the plastic sleeve 1 extends outside the right end surface of the concrete pipe 2 to form a receiving interface;

[0020] A lateral modified rubber sealing ring 3 is fixedly mounted on the right end face of the plastic sleeve 1. When the two concrete pipes 2 are butt-jointed, the lateral modified rubber sealing ring 3 is in sealing contact with the side wall of the plug-in interface at the left end of the concrete pipe 2 to achieve a sealing and water-stopping effect.

[0021] Working principle:

[0022] In this embodiment, a plastic sleeve 1 is fixedly embedded on the right end of the concrete pipe 2, and the right half of the plastic sleeve 1 is used as a receiving interface. The plastic sleeve 1 replaces the carbon steel sleeve structure in the prior art, thereby solving the problem of carbon steel corrosion and reducing the cost of the concrete pipe interface connection structure.

[0023] When the two concrete pipes 2 are butt-jointed, a lateral modified rubber sealing ring 3 is fixedly embedded on the right end face of the plastic sleeve 1. When the plug-in interface of the concrete pipe 2 is close to the receiving interface of the right half of the plastic sleeve 1, the lateral modified rubber sealing ring 3 can be squeezed, thereby achieving effective sealing of the outer contact surfaces of the two concrete pipes 2. Therefore, it can also effectively prevent external rainwater, gravel, etc. from penetrating into the interface gap between the two concrete pipes 2, thereby causing corrosion and wear of the internal rubber sealing ring.

[0024] Embodiment 2, as a further preferred solution of embodiment 1, a plurality of threaded steel nails 4 are radially arranged on the left half of the plastic collar 1, and the threaded ends of the threaded steel nails 4 pass through the plastic collar 1 and are buried in the concrete pipe 2. By arranging the threaded steel nails 4, the threaded steel nails 4 can be buried in the concrete pipe 2 when pouring concrete, thereby ensuring the stability of the connection between the plastic collar 1 and the concrete pipe 2, and preventing the plastic collar 1 from falling off the concrete pipe 2.

[0025] Embodiment 3, as a further preferred embodiment of embodiment 1, at least two water stop rings 5 ​​are arranged on the inner wall of the left half of the plastic collar 1, the water stop ring 5 is buried in the concrete pipe 2, the cross section of the water stop ring 5 is a T-shaped structure, and the water stop ring 5 and the plastic collar 1 are arranged as an integrated structure. By arranging the water stop ring 5 and burying the water stop ring 5 in the concrete pipe 2, the stability of the connection between the plastic collar 1 and the concrete pipe 2 can be ensured, and at the same time, the water stop sealing performance of the connection part between the plastic collar 1 and the concrete pipe 2 can be ensured by the water stop ring 5 of the T-shaped structure, which effectively prevents the sewage in the concrete pipe 2 from seeping out from the position where the plastic collar 1 and the concrete pipe 2 are connected.

[0026] Embodiment 4, as a further preferred embodiment of embodiment 1, the lateral modified rubber sealing ring 3 includes a fixed rubber 31 and a modified rubber block 32, a fixed convex ring 33 is provided on one side of the fixed rubber 31, an annular notch 11 is provided on the right end face of the plastic sleeve 1, the fixed rubber 31 is fixedly installed in the annular notch 11 through the fixed convex ring 33, a hollow cavity 34 is provided in the middle of the fixed rubber 31, an installation groove is provided on the other side of the fixed rubber 31, the modified rubber block 32 is fixedly installed in the installation groove, and the modified rubber block 32 is in sealing contact with the side wall of the plug-in interface of the concrete pipe 2.

[0027] In this embodiment, the fixed rubber 31 can be made of a general rubber material, while the modified rubber block 32 is made of a rubber material that is in a clay-like state, highly elastic, highly compressible and highly adhesive, so as to ensure that the modified rubber block 32 can be stably fixed in the mounting groove of the fixed rubber 31. In this embodiment, the modified rubber block 32 is made of dimethyl silicone rubber. Therefore, when the two concrete pipes 2 are butt-jointed, the modified rubber block 32 can be squeezed, so that the water-stopping effect of the concrete pipe interface position can be effectively ensured by the highly elastic and highly compressible modified rubber block 32. And by setting the hollow cavity 34, when the lateral modified rubber sealing ring 3 is squeezed, the fixed rubber 31 can also have a certain deformation amount, thereby further ensuring the sealing effect of the pipe end face connection part.
