[0031] like Figure 1-5 As shown, an embodiment of the present application discloses a novel prefabricated maintenance well-in-well, comprising a well body 1, an L-shaped block 2, a trapezoidal baffle 3 and a fixing assembly 4.

[0032] The well body 1 has a rectangular cross section, a groove 11 is provided at the intersection between the bottom of the well body 1 and the inner wall of the well body 1, a convex groove 12 matching with the groove 11 is provided at the intersection between the top of the well body 1 and the side wall of the well body 1, a clamping groove 13 is provided at the intersection between the inner wall of the well body 1 and the top of the well body 1, and an expansion groove 14 connected with the clamping groove 13 is provided at the intersection between the inner wall of the well body 1 and the top of the well body 1. The L-shaped block 2 is a block structure with an L-shaped cross section, the L-shaped block 2 is plugged into the clamping groove 13, and a fixing groove 21 is provided on the side wall of the L-shaped block 2. The trapezoidal baffle 3 is a plate structure with a right-angled trapezoidal cross section, the trapezoidal baffle 3 is hinged on the inner wall of the well body 1, and is used for closing and expanding, the side wall of the trapezoidal baffle 3 close to the L-shaped block 2 is provided with a mounting groove 31 matching with the fixing groove 21, and the side wall of the trapezoidal baffle 3 is provided with a sliding groove 32 connected with the mounting groove 31.

[0033] The fixing assembly 4 is installed on the trapezoidal baffle 3 and is used to fix the trapezoidal baffle 3 and the L-shaped block 2.
