[0029] Please refer to the attached Figure 1-Figure 3 , shows a basic device for assembling a TBM in an inclined shaft provided in an embodiment of the present application, comprising: a first concrete layer 3, a second concrete layer 4, an embedded plate 6 and a track 7.

[0030] The first concrete layer 3 serves as a foundation hardening layer and is composed of a steel mesh and concrete. Concrete of ordinary strength can be used; the steel mesh includes vertical steel bars 1 and transverse steel bars 2. The vertical steel bars 1 and the transverse steel bars 2 are fixed by tying wires. The top of the vertical steel bars 1 is exposed from the first concrete layer 3 and is used to connect the embedded plate 6.

[0031] The second concrete layer 4 is fixed on the top of the first concrete layer 3 , that is, the second concrete layer 4 is poured with the upper surface of the first concrete layer 3 as the bottom.

[0032] The embedded plate 6 is embedded into the upper surface of the second concrete layer 4, and the embedded plate 6 is fixedly connected to the vertical steel bars 1 in the steel mesh of the first concrete layer 3 through the extended sleeve 5. The second concrete layer 4 is poured after the embedded plate 6 and the extended sleeve 5 are installed.

[0033] The track 7 is fixedly installed above the embedded plate 6, and a pin hole 8 is opened on the side of the track 7. When a backstop device is installed on the track 7 (the backstop device is used to brake the trailer on the track 7), a pin shaft is passed through the backstop device and the pin hole 8 for easy installation and use.

[0034] In one embodiment, a support leg 601 is fixedly connected to the bottom of the embedded plate 6, and the support leg 601 and the vertical steel bar 1 are respectively inserted into the interior of the extension sleeve 5 from both ends of the extension sleeve 5, and a plurality of fastening screws 9 are threadedly installed on the side of the extension sleeve 5, and the support leg 601 and the vertical steel bar 1 are fixed to the extension sleeve 5 by means of the fastening screws 9.

[0035] The plurality of fastening screws 9 are divided into two groups, corresponding to the supporting legs 601 and the vertical reinforcement 1 respectively. Each group of fastening screws 9 is provided with two fastening screws 9, thereby ensuring a more stable connection.

[0036] The top end of the lengthened sleeve 5 is against the bottom of the embedded plate 6, that is, the legs 601 are all located inside the lengthened sleeve 5, and the structure formed by the lengthened sleeve 5 and the legs 601 is not easily deformed.

[0037] The length of the extension sleeve 5 is generally greater than 2 / 3 of the thickness of the second concrete layer 4 , and the extension sleeve 5 also serves as the skeleton of the second concrete layer 4 .

[0038] In one embodiment, the second concrete layer 4 uses C60 and above compressive concrete. C60 and above compressive concrete has better density and smaller pores, which can make the second concrete layer 4 have higher strength and avoid cracking of the second concrete layer 4.

[0039] In one embodiment, a plurality of pin holes 8 are provided, and the plurality of pin holes 8 are evenly distributed along the length direction of the track 7, so that the backstop device can be installed at multiple positions of the track 7, and lubricating oil is applied inside the pin holes 8, and the pins are placed inside the pin holes 8 to get stuck.
