Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The invention discloses a shield segment assembling type positioning tenon structure which comprises a positioning tenon body 6, wherein the positioning tenon body 6 comprises a first trapezoidal platform 1 and a second trapezoidal platform 2, the lower bottom surfaces of the first trapezoidal platform 1 and the second trapezoidal platform 2 are fixedly connected, and a connecting cavity 3 is axially arranged on the positioning tenon body 6. A plurality of annular adhesive grooves 4 are arranged on the outer side surface of the first trapezoidal platform 1 or the second trapezoidal platform 2. Preferably, first trapezoidal platform 1 or second trapezoidal platform 2 are fillet trapezoidal platform, and first trapezoidal platform 1 is not necessarily the same with the structure of second trapezoidal platform 2, can be according to the modification of the structure adaptability of shield structure section of jurisdiction. Preferably, both sides of the first trapezoidal platform 1 and the second trapezoidal platform 2 are cambered surfaces 5. Preferably, a steel sleeve is embedded in the positioning tenon body 6 and arranged around the connecting cavity 3, wherein the positioning tenon body 6 is a plastic positioning tenon. Preferably, the positioning tenon body 6 can also be a steel positioning tenon.
Example 1:
the invention discloses a shield segment assembling type positioning tenon structure which comprises a positioning tenon body 6, wherein the positioning tenon body 6 comprises a first trapezoidal platform 1 and a second trapezoidal platform 2, the lower bottom surfaces of the first trapezoidal platform 1 and the second trapezoidal platform 2 are fixedly connected, and a connecting cavity 3 is axially arranged on the positioning tenon body 6. A plurality of annular adhesive grooves 4 are arranged on the outer side surface of the first trapezoidal platform 1 or the second trapezoidal platform 2. The first trapezoid table 1 or the second trapezoid table 2 are both round-angle trapezoid tables.
