Technical Field
[0001] This utility model relates to the field of sealing application technology, and in particular to a concrete pipe joint connection interface that facilitates sealing connection. Background Technology
[0002] Reinforced concrete pipes are widely used in drainage engineering, mainly for the discharge of rainwater and sewage. These pipes can be classified in different ways. According to the joint type, reinforced concrete pipes can be divided into four types: plain end, tongue and groove, double spigot, and steel socket. According to the manufacturing process, these pipes can also be divided into roller-driven pipes, centrifugal pipes, core-mold vibrating pipes, radially extruded pipes, and vertically vibrating pipes.
[0003] Steel-socket reinforced concrete pipes, as a type of reinforced concrete pipe, play a crucial role in municipal construction projects. However, during use, steel-socket reinforced concrete pipes are prone to leaks due to sealing problems; in severe cases, mud and sand may even flow into the pipe, causing ground subsidence and leading to more serious safety accidents. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a concrete pipe joint connection interface that is convenient for sealing and connection. This water-stop interface can effectively seal the pipe and prevent water leakage accidents; furthermore, it can prevent the problem of mud and sand from flowing into the pipe and causing ground subsidence.
[0005] To solve the above-mentioned technical problems, the solution of this utility model is as follows:
[0006] A concrete pipe joint connection interface for convenient sealing includes a rigid annular connection port A connected to one end of the concrete pipe joint and a rigid annular connection port B connected to the other end of the concrete pipe joint. The rigid annular connection port A has an annular sealing groove A and an annular retaining groove A on its inner side. The rigid annular connection port B has an annular sealing groove B corresponding to the annular sealing groove A and an annular retaining groove B corresponding to the annular retaining groove A on its outer side.

An injection hole communicating with the annular sealing groove A is provided on the rigid annular connection port A. A support and anti-reverse retaining strip is provided inside the annular retaining groove A and the annular retaining groove B.
[0007] The sealing strip and the supporting anti-reverse strip have a C-shaped structure.
[0008] The sealing strip includes a steel sealing strip and a rubber sealing layer disposed on the outside of the steel sealing strip.
[0009] It also includes sealant injected into the annular sealing groove A and the annular sealing groove B through the injection hole.
[0010] Both the annular sealing groove A and the annular sealing groove B have corresponding semi-circular hole structures in their cross sections.
[0011] Both the annular slot A and the annular slot B have correspondingly designed square structures in cross-section.
[0012] The cross-section of the support anti-reverse strip is a wedge-shaped structure or a right-angled trapezoidal structure.
[0013] The support anti-reverse strip is a rigid structure made of rigid material.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] This application connects rigid annular connection ports A and B by embedding sealing strips inside annular sealing grooves A and B, and inserting support and anti-reverse strips inside annular slots A and B, thereby connecting and sealing adjacent concrete pipe sections together. Furthermore, by injecting sealing material into annular sealing grooves A and B through injection holes, the sealing between concrete pipe sections is further ensured, effectively preventing water leakage. Simultaneously, the support and anti-reverse strips not only effectively prevent displacement between rigid annular connection ports A and B, ensuring the integrity of the concrete pipe sections, but also provide support for rigid annular connection ports A and B, enhancing their rigidity and effectively preventing water leakage and collapse accidents caused by pipe sections.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0023] like Figure 1-6 As shown; a concrete pipe joint connection interface for convenient sealing connection includes a rigid annular connection port A1 connected to one end of the concrete pipe joint and a rigid annular connection port B2 connected to the other end of the concrete pipe joint. The inner side of the rigid annular connection port A1 is provided with an annular sealing groove A3 and an annular retaining groove A4. The outer side of the rigid annular connection port B2 is provided with an annular sealing groove B5 corresponding to the annular sealing groove A3 and an annular retaining groove B6 corresponding to the annular retaining groove A4. A sealing strip 7 is provided inside the annular sealing groove A3 and an injection hole 10 communicating with the annular sealing groove A3 is provided on the rigid annular connection port A1. A support and anti-reverse retaining strip 11 is provided inside the annular retaining groove A4 and annular retaining groove B6.
[0024] In this application, by connecting the rigid annular connection port A1 and the rigid annular connection port B2, and by embedding the sealing strip 7 inside the annular sealing groove A3 and the annular sealing groove B5, two adjacent concrete pipe sections can be connected and sealed together. Furthermore, by injecting sealing material into the annular sealing groove A3 and the annular sealing groove B5 through the injection hole 10, the sealing between the concrete pipe sections is further prevented, effectively preventing water leakage. At the same time, due to the setting of the support anti-reverse strip 11, during application, displacement between the rigid annular connection port A1 and the rigid annular connection port B2 is effectively prevented, ensuring the integrity between the concrete pipe sections. Moreover, the support anti-reverse strip 11 can also support the rigid annular connection port A1 and the rigid annular connection port B2, enhancing their rigidity.
[0025] Furthermore, multiple annular sealing grooves A3 and B5 can be provided to further enhance the sealing performance; and multiple injection holes 10 can be provided on each annular sealing groove A3 to facilitate the rapid filling of injection molding material.
[0026] The sealing strip 7 and the support anti-reverse strip 11 have a C-shaped structure. The C-shaped structure facilitates installation and insertion.
[0027] The sealing strip 7 includes a steel sealing strip 8 and a rubber sealing layer 9 disposed on the outside of the steel sealing strip 8. The steel sealing strip 8 has a rigid function, which can support and protect the rigid annular connection A1 and the rigid annular connection B2. This reduces the possibility of ground subsidence and effectively ensures construction quality.
[0028] It also includes the injection of sealant into the annular sealing grooves A3 and B5 through the injection hole 10. The sealant, in conjunction with the sealing strip 7, further seals the rigid annular connection A1 and rigid annular connection B2, ensuring the airtightness between the concrete pipe sections.
[0029] Both annular sealing grooves A3 and B5 have corresponding semi-circular hole structures in their cross-sections. The semi-circular hole structure of annular sealing grooves A3 and B5 facilitates the quick installation of sealing strip 7.
[0030] Both annular slots A4 and B6 have corresponding square cross-sections. The square structure mainly facilitates the installation of the anti-reverse strip 11 and effectively prevents displacement between the rigid annular connection port A1 and the rigid annular connection port B2. During the production process, an insertion port communicating with the annular slot B6 is provided on the inner side of the rigid annular connection port B2 to facilitate the insertion support of the anti-reverse strip 11, thereby facilitating installation.
[0031] The cross-section of the support anti-reverse strip 11 is a wedge-shaped structure or a right-angled trapezoidal structure. The support anti-reverse strip 11 with a wedge-shaped or right-angled trapezoidal cross-section can be easily inserted and prevented from retraction, effectively preventing displacement between the rigid annular connection A1 and the rigid annular connection B2, ensuring the stability between the rigid annular connection A1 and the rigid annular connection B2, thereby ensuring the stability between the concrete pipe sections.
[0032] The support and anti-reverse strip 11 is a rigid structure made of rigid material. The rigid support and anti-reverse strip 11 can effectively provide support, further ensuring the cross-sectional strength of the rigid annular connection A1 and rigid annular connection B2, and preventing accidents such as water leakage and collapse caused by pipe cutting.
[0033] In application, this application uses sealing strips 7 embedded inside annular sealing grooves A3 and B5, and support anti-reverse strips 11 inserted into annular slots A4 and B6, to connect rigid annular connection ports A1 and B2, further connecting and sealing adjacent concrete pipe sections together. Furthermore, sealing material is injected into annular sealing grooves A3 and B5 through injection holes 10, further ensuring the sealing between concrete pipe sections and effectively preventing leakage. Simultaneously, the support anti-reverse strips 11 not only effectively prevent displacement between rigid annular connection ports A1 and B2, ensuring the integrity of the concrete pipe sections, but also support rigid annular connection ports A1 and B2, enhancing their rigidity and effectively preventing leakage and collapse accidents caused by pipe sections.
[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
