[0005] The top end of the T type sealing strip is arc structure, the arc structure is attached on the sealing groove at the connecting place of the main part, and is used for completely covering the sealing groove,
[0006] The bottom end of the T type sealing strip is designed with angle barb, and the barb is located in the sealing groove and is used for preventing falling off.
[0007] The main part of the T type sealing strip is connected with the top end and the bottom end.
[0008] Further, the longest length of the arc structure is 28mm.
[0009] Further, the longest length of the barb is 9mm.
[0010] Further, the distance from the top of the main part to the bottom of the bottom end is 9mm.
[0011] Further, the total height of the T type sealing strip is 12mm, that is, the distance from the top of the arc structure to the bottom of the barb is 12mm.
[0012] Compared with the prior art, the utility model has the beneficial effects that:
[0013] The T-shaped sealing strip is not only ensured not to leak slurry in the production process, but also enhances the protection of the sealing strip, making it more durable. By reducing the breakage and replacement frequency of the T-shaped sealing strip, the service life and production efficiency are improved, successfully solving the problems of easy falling off, damage and frequent replacement of the automatic cover plate sealing strip, providing reliable protection for efficient production and pipe product quality.

[0017] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.
[0018] The specific implementation of the utility model is described in detail below in combination with specific examples.
[0019] As shown in Figure 1 and Figure 2 , a T-shaped sealing strip provided by one embodiment of the utility model is installed in the inner arc surface of the automatic cover plate 01 to form a sealing area, and is tightly combined with the outer edge of the mold to realize sealing. The T-shaped sealing strip 02 is composed of a top end 021, a main body 022 and a bottom end 023.
[0020] The top end 021 of the T-shaped sealing strip 02 is in an arc structure, and the longest length of the arc structure is 28 mm. The connection between the arc structure and the main body 022 is attached to the sealing groove, completely covers the sealing groove firmly, prevents impurities such as concrete from entering the sealing groove, and plays the roles of sealing and not being easy to be turned up.
[0021] The bottom end 023 of the T-shaped sealing strip 02 is designed with a certain angle of barb, and the longest length of the barb is 9 mm. The barb is located in the sealing groove, effectively prevents the T-shaped sealing strip 02 from falling off, and enhances the connection stability between the T-shaped sealing strip 02 and the sealing groove.
[0022] The main body 022 of the T-shaped sealing strip 02 connects the top end 021 and the bottom end 023, and the distance from the top of the main body 022 to the bottom of the bottom end 023 is 9 mm. The main body 022 ensures the stability and structural integrity of the entire T-shaped sealing strip 02.
[0023] The total height of the T-shaped sealing strip 02 is 12 mm, that is, the distance from the top of the arc-shaped structure to the bottom of the barb is 12 mm.
[0024] In the embodiment of the utility model, after the automatic cover plate 01 with the installation groove is ready, the T-shaped sealing strip 02 is installed in the inner arc surface of the automatic cover plate 01 to form a sealing area, and the mold outer edge is stressed to be tightly sealed. The top end 021 of the T-shaped sealing strip 02 adopts an arc-shaped structure, which can be firmly attached to the sealing groove and completely cover the sealing groove, preventing impurities such as concrete from entering the sealing groove and achieving the effects of sealing and not easy to turn up. The lower end is designed with an angle barb, which effectively prevents the T-shaped sealing strip 02 from falling off. This design not only ensures that there is no slurry leakage during production, but also enhances the protection of the T-shaped sealing strip 02, making it more durable. By reducing the damage and replacement frequency of the T-shaped sealing strip 02, the service life and production efficiency are improved, successfully solving the problems of easy falling off, damage and frequent replacement of the sealing strip of the automatic cover plate 01, and providing reliable protection for efficient production and segment product quality.
[0025] The above is only the preferred embodiment of the utility model, and it should be pointed out that for those skilled in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which should also be considered as the protection range of the utility model, and these will not affect the effect and practicality of the utility model.
