[0021] See also Figure 1-Figure 5 As shown, an anti-seepage component for a steel socket jacking pipe comprises a jacking pipe body 1, a steel socket 2 being installed at one end of the jacking pipe body 1, a socket 8 being provided at the other end of the jacking pipe body 1, the steel socket 2 of the jacking pipe body 1 being plugged into the socket 8 on the adjacent jacking pipe body 1, a rubber ring 3 being installed at the end of the jacking pipe body 1 facing the steel socket 2, one end of the rubber ring 3 being in contact with one of the jacking pipe bodies 1, and the other end of the rubber ring 3 being in contact with the socket 8 of the other jacking pipe body 1, a groove 4 being provided in the middle of the rubber ring 3, a fixing ring 5 being engaged in the groove 4, and the fixing ring 5 being fixed to the jacking pipe body 1 by a plurality of expansion bolts 7.

[0022] As a technical optimization solution of the present invention, the cross-section of the steel socket 2 is an "L"-shaped structure, one end of the steel socket 2 is arranged inside the outer wall of the jacking pipe body 1, and the other end of the steel socket 2 extends toward the end of the jacking pipe body 1 to form a socket; the strength of the socket of the jacking pipe body 1 is increased, and the socket of the jacking pipe body 1 is effectively prevented from being broken.

[0023] As a technical optimization solution of the present invention, the overall cross-section of the rubber ring 3 is a "concave"-shaped structure, and the side of the rubber ring 3 that contacts the steel socket 2 is a trapezoidal structure. The outer diameter of the rubber ring 3 is larger than the outer diameter of the fixing ring 5, and the inner diameter of the rubber ring 3 is smaller than the inner diameter of the fixing ring 5; since the cross-section of the rubber ring 3 facing the steel socket 2 is a trapezoidal structure, when the socket 8 drives the rubber ring 3 to move toward the first jacking pipe body 1, the contact area between the rubber ring 3 and the steel socket 2 is in an increasing state, thereby making the rubber ring 3 and the steel socket 2 tightly connected, thereby making the sealing performance of the rubber ring 3 better, and achieving a good anti-leakage effect.

[0024] As a technical optimization solution of the present invention, the cross-section of the fixing ring 5 is a rectangular structure, and the thickness of the fixing ring 5 is less than the thickness of the rubber ring 3; the thickness of the fixing ring 5 is less than the thickness of the rubber ring 3, thereby avoiding the inability of the socket 8 to contact the rubber ring 3 due to the excessive thickness of the fixing ring 5, thereby avoiding the presence of gaps and leakage at the connection between the two jacking pipe bodies 1.

[0025] As a technical optimization solution of the present invention, a plurality of countersunk holes 6 are provided on the fixing ring 5, and the plurality of countersunk holes 6 are distributed in a circular array about the center of the fixing ring 5; one end of the expansion bolt 7 is arranged inside the top pipe body 1, and the other end of the expansion bolt 7 is arranged inside the countersunk hole 6; the setting of the countersunk hole 6 facilitates the installation of the expansion bolt 7, so that the expansion bolt 7 is installed inside the fixing ring 5, avoiding the expansion bolt 7 affecting the sealing of the rubber ring 3.

[0026] When the utility model is in use, first install the fixing ring 5 in the groove 4 in the middle of the rubber ring 3, then place the rubber ring 3 on the end of the jacking pipe body 1 where the steel socket 2 is installed, and then press the fixing ring 5 in the direction of the jacking pipe body 1, so that the fixing ring 5 drives the rubber ring 3 to press against the end face of the jacking pipe body 1, and then use the expansion bolt 7 to fix the fixing ring 5 and the rubber ring 3 on the jacking pipe body 1, so that the fixing ring 5 is fixed and cannot slide out of the groove 4, thereby fixing the rubber ring 3. The installation of the fixing ring 5 has a shaping and supporting effect on the rubber ring 3, so that the rubber ring 3 is pressed against the inner wall of the steel socket 2 to the outside, and the rubber ring 3 and the fixing ring 5 are fixed by the expansion bolt 7, so that the installation of the rubber ring 3 is more stable and the sealing is better; the thickness of the fixing ring 5 is required to be not greater than the thickness of the rubber ring 3, so as to avoid the socket 8 being unable to contact with the rubber ring 3 due to the thickness of the fixing ring 5 being too thick, thereby avoiding the gap at the connection between the two jacking pipe bodies 1 and leakage; the setting of the countersunk hole 6 is convenient for installing the expansion bolt 7 , so that the expansion bolt 7 is installed inside the fixing ring 5 to prevent the expansion bolt 7 from affecting the sealing of the rubber ring 3; then the socket 8 of the second jacking pipe body 1 is pushed into the steel socket 2 of the first jacking pipe body 1, and when the socket 8 conflicts with one end of the rubber ring 3, the socket 8 drives the rubber ring 3 to move toward the first jacking pipe body 1, and makes the other end of the rubber ring 3 further press against the first jacking pipe body 1, so that the two jacking pipe bodies 1 are tightly connected and have good sealing performance; when the rubber ring 3 conflicts with the socket 8 on the second jacking pipe body 1 and the end of the first jacking pipe body 1, the side wall of the rubber ring 3 conflicts with the inner wall of the steel socket 2, and because the cross-section of the side of the rubber ring 3 facing the steel socket 2 is a trapezoidal structure, when the socket 8 drives the rubber ring 3 to move toward the first jacking pipe body 1, the contact area between the rubber ring 3 and the steel socket 2 is in a progressively increasing state, so that the rubber ring 3 and the steel socket 2 are tightly connected, thereby making the sealing performance of the rubber ring 3 better and achieving a good anti-leakage effect.

[0027] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
