Example 2
A shield segment assembling method is based on the shield segment with a connecting device in the embodiment 1.
The method comprises the following steps of:
s1, positioning and installing a splicing duct piece 12;
S2, installing a basic duct piece 11 and a right transition duct piece 14 along two ends of the plugging duct piece 12 in the circumferential direction through first connecting components respectively;
S3, installing the residual foundation duct piece 11 through a first connecting assembly sequentially at one end, far away from the splicing duct piece 12, of the foundation duct piece 11 in the circumferential direction;
S4, installing a left transition duct piece 13 along one end of the finally installed base duct piece 11 in the circumferential direction;
S5, sliding the capping segment 15 through the second groove 22 and installing the capping segment between the left transition segment 13 and the right transition segment 14 through the first connecting assembly to form a layer of annular pipeline;
S6, installing the segment body through the second connecting component 4 along the axial direction of the annular pipeline according to the installation steps of S1-S5, and forming a tunnel after installing a plurality of annular pipelines.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
