[0002] With the development of large-scale infrastructure renewal in my country, more and more tunnels need to be built in water diversion projects, hydropower projects, and municipal projects. Due to the high requirements for construction speed and quality, traditional construction methods can no longer meet current needs. TBM is widely recognized and applied due to its fast construction progress.

[0003] In the existing technology, tunnel boring machines / shield machines are usually used in highway and railway tunnel construction, and are rarely used in the milling and expansion of laid pipes. According to the characteristics of pipeline laying in current water conservancy projects and municipal engineering projects, traditional TBMs have poor applicability, especially in the key core process of support shoes, which usually occupy a large space and cause difficulties in the transportation of materials and personnel maintenance during construction.

[0020] Furthermore,

[0021] The driving oil cylinder is connected to the two support shoes by a detachable pin shaft connection.

[0022] The pinning method of the pin shaft connection is to insert the pin from top to bottom;

[0023] After the driving cylinder is separated from any one of the gripping shoes, the driving cylinder can be deflected in the horizontal direction around the connection point between the other gripping shoe and the driving cylinder.

[0024] Furthermore,

[0025] The cross section of the support shoe toward the central axis of the device body is a concave shape, and the connection between the driving cylinder and the support shoe is located at the lowest point of the concave shape;
